The problem to be solved by the invention

The method of blowing out the formed container from the double-type (blank) includes the cold blank method or the so-called two-stage method, and the hot blank method, as well as the stage method. In any case, the spot injection molding necessary for the capacity group blow molding must have at least the injection socket filling of the specified spot outer wall and the injection core of the specified embedded inner wall. In addition, it will be more than the injection surface filling and injection. Shenqitian press,. After molding a prototype by injection_lThe state of the French chess must be maintained, and the type-finding must be cooled to a temperature where it can be removed.

Especially in terms of the cold blank (two-stage) method, the de-filling temperature of this type finding must be very low, so as to increase the expansion time of injection molding and cause the deterioration of production efficiency. That is, after the injection of the overfill and the injection of the S chess to unfill the molding, press the pile type. When taking out, the embedded type must be cooled to a sufficiently low release temperature, so that the garbage type and other components will not be smashed. shape.

The pile is made in the cold and vigorous material method, divided into the form-finding forming step field, and the step of forming the forming container from the spot type.^：However, in terms of cold embryo method, it is necessary to reheat the bamboo when it reaches room temperature to find the shape. It is efficient to seal the sound in the skull, and the spot hot embryo is continuous color.

On the other hand, from the stretch that maintains the heat of injection molding, the injection extension of the hot material (one-stage) method of blowing out the molded bottle, the injection molding process is determined by the time-consuming injection molding cycle time of the whole finger to detect the middle rock. The device is fully locked. W forming preparation time. Therefore, if it takes a long time for the injection to match the shape, it includes the intermediary of the sinking of the bear in the whole ceremony of the generating device. ,

In terms of stacking with hot blanks, although the bulk temperature of blanks is higher than that of cold blanks, the de-filling temperature has its own precision and cannot speed up the injection molding finger filling as fast as possible. Therefore, increase the release temperature of the mold-finding, and when the loose mold is released from the injection core, the embedded mold is tightly attached to the core filling, and defective removal such as interlude occurs. But after the ejection core is out of the game, the eye-shaped and loose-shaped bracts no longer exist. Due to the partial temperature or the heat-retracting rule, the shape cannot be taken out to find the shape according to the needle setting. In addition, due to insufficient cooling of the injection molding, especially the spotted inner wall, crystallization due to insufficient cooling, including the spotted hole with unclear removal.

In addition, when the mold-finding is taken out before the injection core is filled and the injection cavity is completely cooled (the mold is kept at a temperature that can be molded), and then blown out, the following problems are involved.

(A) Those who do not catch Takauchida (maintain the power of the shot field) will be stained in the spot-type shot nest as usual, and cannot get the type finding of the uniform sentence temperature. Therefore, this spot type cannot lead to molded products with uniform thickness distribution during blow molding.

(B) For those who increase the inner seat (except for the ejection force), the interface part and the spotted end part (m such as the spine part) are combined with the Kyosei Maruza" to become Gaozhuangs model-finding remnant whale with a strong bottom force. Type finding_：. Therefore, in the quotient of blow molding, a molded product with a uniform thickness cannot be obtained.

(C) The spot type flexes when the injection core filling and the injection socket filling are cooled. When the cooling is in progress, attach the Changbi brand to the direction of the injection socket surface. Because of the change, the "outer wall surface of the embedded mold" is the part that is in contact with the injection socket and the part that is not in contact with the injection socket. The sentence of "uneven warming" is formed due to the difference in the degree of mold-finding and cooling. Therefore, it is impossible to obtain molded products of uniform thickness when the splinter type is blow-molded.

In the same way, if the conventional hot blank material is not used to fully cool the bulk by injection nest filling and injection waste filling, it will not be able to get the carded blow-out holding or bottle character. Therefore, release injection molding When set, the output of the device is also reduced.

As the hot blank material injection extension reflects other problems of the forming ladder, the following inserting problems have been solved.

One is that in order to improve the production efficiency, such as increasing the injection molding pattern and simultaneously forming the eagle inlay H, it is necessary to form and inlay H nests relative to the shape of the bottle in the blowing cavity. Among the gold solid structures used in Geng Chu Shaping Ladder, although Geng Chu Wo Kou Liang is the real gold structure, the price of piles increases approximately in proportion to the commercial inlays. Even if Kunshi Jintian is very cost-effective as long as the operation rate is increased, as mentioned above, the cycle time of the entire device is limited by the injection molding cycle time and cannot be shortened. Therefore, the operation rate of the simple blow-out mask will naturally decrease._.In addition, if the number of simultaneous blow moldings is increased, not only will the blow out of the nest filling be justified, but the extension distance, blow out S filling, and supporting or distance-moving inlay structures will also be increased, leading to larger devices and higher prices.

Other well-known problems are that if the injection core cannot be completely pulled out from the release mold, that is, the prototype cannot be taken out, and the release mold cannot be transported from the injection molding part to the next step with a rotary injection molding device. At this time, when the model is completely pulled out from the injection mechanism, the length of the drawing surface is increased, and the height of the stringer of the device is increased.

In addition, there is another question that the hot blanks are reflected in the rotary transfer type blow molding street._：At the time of molding, the projected shape finding is rotated and conveyed to the blow-out molding section. Therefore, for example, when an abnormality occurs in the blow-out forming part, it is not necessary to stop the form-finding work-out forming. However, once the injection molding part stops, it takes a long time to prepare for the ear activation. Because the injection device, the hot filter channel type, etc. all need a lot of connection and modification of the finger heating connection structure.

Therefore, as mentioned above, in addition to the fact that the full-finger production tool of the device cannot be improved, once an abnormality occurs, the preparation of the device takes a lot of time, which results in a lower production efficiency.

Therefore, the purpose of the great invention is to provide an injection stretch blow molding method that can fully ensure the cooling time of the prototype, while shortening the injection molding life time, thus shortening the pointing time of the device.

The second purpose of the invention is to provide a high-efficiency injection-stretching blow molding method, which can reduce the number of blow-out pockets to reduce costs, and at the same time increase the blow-out operating vehicle.

Another purpose of the invention is to provide an injection stretch blow molding method, which produces the thermal energy efficiency of the hot blank method and the stability of the temperature distribution of the cold blank method.

Another purpose of the great invention is to provide a one-shot stretch blow molding method, even if the mold-finding removal temperature from the injection die is increased, it can still prevent partial temperature or shape-fitting, and in the mold-finding self-injection S It can be sufficiently cooled before filling, and then stabilized in the blow molding process for blow molding.

Another purpose of the great invention is to provide an injection-stretching blow molding method, which can use the injection core mold and the injection cavity to fill the bulk inner and outer wall with the temperature difference and the state, and then blow the molding.

The great invention is to provide an injection stretch blow molding method, which can blow out common medium-sized containers with a capacity of 1 to 3 liters with high efficiency.

Another object of the great invention is to provide a method of injection stretch blow molding, which does not perform blow molding indiscriminately when the device is ready to start, or when there is an abnormality in the blow molding part, it is not necessary to stop the device and refer to the operator.

Soya solves the problem of spot enrichment and B-glycation of frame head

The first item of patent application is an injection stretch blow molding method using a prototype blow molding container that retains the heat of injection molding. De-filling step spot: While the type-finding is kept in the state of shooting and filling, use the method to shoot S-filling to cool down the string type-finding, and at the same time transport the shot core chess to the step of taking out the way along the stack. Spot: At the pressing and taking out part, the string ejection core is filled and demolded from the spot to take out the spot for finding the spot: Then, the spot for forming the string container is reflected by the string spot that keeps the injection molding heat.

According to the invention of the first item of the patent application, the spot shape is injected in the injection molding part, and the injection cavity is filled and the injection core is cooled.^'Only the ejaculate waffle escapes from the patch type. Then the mold is filled with the injection core and sent to the mold-finding and take-out part. During this transportation and in the mold finding and extraction part, the injection core is used to cool the position pattern, and then the mold finding is carried out. Therefore, even after the injection cavity is filled and unfilled in the injection molding part, when the injection is cooled by S times, the cooling time for the mold finding can be sufficiently ensured. Therefore, when the injection molding part is pressed and released in the injection molding part, the release temperature of the insert type can be increased, the injection molding time of the ring can be shortened, and the settling time of the entire device can be reduced. , It can also prevent the inlaid type from being shaped like an S chess_.However, because the spot type is cooled and shrinks, it is closely attached to the injection core, which can improve the cooling efficiency. Prevent eye crystallization and unevenness caused by insufficient cooling. Due to the stabilization of the cooling step, the heat and stability of the mold-finding can be maintained, and the thickness distribution of the blown-formed containers can be stabilized.

The invention described in item 2 of the patent application is an injection-stretched projection molding method, which consists of a spot-shaped blow-molded container that retains the heat of injection molding, and is characterized by including: at least H of the injection structure and the injection cavity structure are used. (Ng2) The spot shape, the step of filling the mold by the injection quotient: In the state where the mold is filled with the injection core, use the string injection core mold to cool the mold, and at the same time, the injection core is filled along The first finger filling conveying path, the step of conveying to the take-out part: in the take-out part, the injection 8 is taken out of the form-finding to take it out. The embedding according to the prototype step: the taken form-finding is transferred to The step of controlling the disengaged conveying member along the second-time shuttle route: the conveying member supporting the push-pull type is conveyed to the blow-out forming part along the second embedding route of the string: in the blow-out forming part, In relation to_nOne (1gn(H) is blown out and filled according to the spot-shaped foot-filling, and n spots are simultaneously reflected and shaped according to the type found into n spots according to the container.

According to item 2 of the scope of patent application, it has the invention of item 1 in the scope of patent application and the following additional functions and effects_.That is, since the number of injection molding at the same time, n is set to be less than the number of injection molding at the same time, so the simple number of injection molding can be reduced, and the cost of consumables can be greatly reduced. In addition, the blow-out wiping mold, the extension pinch, and the support or distance ladder structure can be reduced, and the device can be miniaturized and low in price. In addition, in the short and short ring shaped ring,-will find the shape of the same shape, each time n. (n(H) is divided into multiple blow molding, so increase the number of reflections of the nest mold. Operate the car.

In contrast, in the second inserting path, a heating part can be provided to heat the t-string that is conveyed to the string blowing and forming part. In this way, the use of injection molding metal filling and cooling, and cooling spot type reheating, can make the bulk type reach the appropriate temperature for forming, and improve the temperature stability of each backup ring. In addition, H mold-finding for injection molding at the same time, even if every time_nIt is divided into (H/n) times to reflect the forming, and it is also easy to control the temperature of each blow-out forming with very little variation.

In addition, when the heated string type-finding gauge rotates at the center of the axis, there is little uneven heating, and the temperature difference in the circumferential direction can be based on the less spot type.

In addition, the second circulating conveying part has a re-conveying add-on, which can be embedded and conveyed at an interval on the second conveying path. Each conveying part has a supporting part, which can support the string-finding in an inverted or upright state. At this time, the arrangement spacing of the retrieving commercial inserts on the second conveying path is preferably set to be equal to the retrieving nest arrangement spacing P of Geng Chutian. It is caused by infrequently changing the spacing during transportation. In this way, the spot spacing of the heating part of the present invention is well known in the art. In the case of the two-stage type, the bleed spacing of the heating part is configured to be large. However, in addition to the heat retained after injection molding, the present invention adds a little heat energy. That is enough, so the heating time can be shortened, and there is no need to lengthen the full length of the heating part like cold blanks._.

In addition, the method of the great invention is shown in item 3 of the patent application. After the core is ejected and the molding step starts to be blown out, the temperature difference between the inner and outer walls of the mold is connected and found, and sufficient time can be ensured. Look for the cool spot. When the method of the present invention is dragged here, the cooling time of the injection S filling of the close-fitting and loose-type inner wall can be used to ensure that the longer is known. Therefore, a more preventive temperature gradient occurs on the cross-section of the release wall, and the temperature near the outer wall The vicinity of the inner wall is high. Since the phosphorus mold is removed from the injection core mold and transferred, the temperature of the inner wall of the release mold rises due to the heat transfer from the outer wall, but the temperature of the outer wall decreases due to the heat transfer. Therefore, the temperature gradient of the cross section of the prototype can be alleviated, and the inner and outer walls of the release can reach the proper temperature for blowing.

In addition, the method of the present invention uses n (ng2) blow sockets arranged at the blow molding pitch P in the blow molding step spot, and at the same time_nThe aforementioned type-finding blow molding n containers, and the type-finding inspection and delivery spot on the second conveying path is to maintain the arrangement spacing of the conveying members equal to the shell spacing P to convey the baby spot type, which is in the embryonic form. The transfer step spot is to transfer n type finding to the step field of n conveying members at the same time, and it is better to repeat it many times.

In this way, in addition to the difference between the conveying distance on the second conveying road, the simultaneous injection molding and transportation can be increased._nWhen the number H is transferred at the same time, it is small, and it is easy to accurately determine the position on the conveying member, so there is no need to adopt a complicated description.

The invention of No. 7 of Shen Yu's patent is an injection-stretching molding method. The injection-molded insert is transferred from the spot-shaped forming magic transfer station to the blow-out forming station. The pattern is transformed and formed into a container, and its characteristics are: at the string-pattern forming station, the pattern is collapsed into an upright state with the opening and the lock part facing upwards: at the string transfer station, the pattern-finding in the upright state Inverted and transferred to the press blow molding station in the inverted state: at the string blow molding station, the container is blown and molded from the inverted state of the loose-type blow molding station.

Patent application room_-Item 7_lThe invention J is that the grid is shaped into an upright state with the maggot facing upward. Therefore, the injection field fill is a perfect fill, which can save space. Since the street finger is usually filled from the bottom side of the type-finding, a stable configuration is adopted, which is arranged under the inclination of the injection device and the injection supplier, and filled in the upper side of the injection 8. When it is transported to the blow molding station, the drawing system is in an inverted state.^'By using the neck opening, the connector can easily stand on its own. In addition, the extension kneading core mold is located below the Dai type, which can be configured using the space in the machine to reduce the full finger height of the blow molding part.

The eighth invention of Cheli Jiangu has been applied for, and its characteristics are: using at least injection core filling and injection molding supplier filling, and at the same time H inserts made of ethylene terephthalate inlay type injection molding. The step of demolding the mold from the injection cavity mold: and the current string-finding in the injection S pseudo-cooling, and at the same time conveying to the ejecting part. The step of removing the inlay-finding from the inlay-shooting endurance and taking out 3: The step of heating the removed string-finding to the normal temperature: Then, by_nAt the same time, the stack type is blown out and formed into a solid container of Auda: Among them, H and n are simultaneously formed and embedded respectively, which is set to H:n:3:1.

According to the mother of the great invention, when the market is about 1~3 liters than the commonly used medium-sized container with the mouth (the opening diameter of the head 2 is about 28-38nn), the inlay H and the_nThe ratio is most suitable to be set as N:n:3:1. That is to say, after the wood invention is released from the injection line, the reward is in the injection core to cool the embedded type._rThen when reflecting and forming, usually medium-sized_：：Allow_：The time required to find the shape of the device is compared with the conventional injection extension and the shape is shortened by about 3/4. It can be seen that the injection molding ring time is about 10-15 silicon. On the other hand, the blowing molding ring time It is about 3I6~4.0 seconds. Therefore, suppose the injection molding cycle time is T1, and the blowing molding ring time is T2, which is about Tl:T2:3:1 to solidify. When the medium-sized capacity group is commonly used for forming with good efficiency, the units H, n are formed at the same time, according to the above The ratio setting is most suitable.

The mth invention of the patent application is the simultaneous injection molding of H (H giant 2) mold-finding spots, and n (1S)_nH_ln, let HIn be the distance cause.

H/_nFor finger placement, for example, the H prototypes that are formed at the same time in the first ring are injected, and the H/n distance is completely blown out every time, which is not compatible with the H positions that are formed at the same time in the second cycle. Any mixing and blowing out at the same time. If it is mixed with different spot patterns of the injection-molded ring and the reflection molding, its conveying top sequence is different from the mold-finding of the same injection-molding ring molding at the same time. The control and structure are repeated. borrow.

The nth invention of Shenqing Patent Jiangu is an injection stretch blow molding method. The injection molding is found in the bulk molding part, and the specific insert is checked to the blow molding part. It is formed into a container, and its characteristics are: it has the air-speaking forming action mode, and the inlay forming action mode. Gong Huanzhi Auda: When the award is changed to the string-finding forming action mode, the string-finding forming part is changed. To find the shape of repeated forming, in the spot-shaped street conveying path toward the string blowing forming part, and the one that is discharged outside the child conveying path^.

According to the invention of the first item in the scope of the patent application, the defective shape-finding can be discharged at the beginning of forming without conveying to the blow-out forming part, and unnecessary blow-out forming is not necessary. In addition, when the forming part is abnormal or slightly growing, even without stopping the operation of the prototype forming part, maggots can be repaired and the fingers can be adjusted to blow out the forming part. Once the insert forming part is powered off, various heating configurations will be able to be formed. It takes a lot of time to embed, but in accordance with this limitation, there is no need for useless embed time.

Therefore, when moving the first cylinder 82, the head seat_：6_j5 and the pre. part fixed press 64, the long-distance is from the first piston stroke 82a, the socket distance stroke 88 and the driven stroke 68, resisting the biasing force of the recovery spring 74 and lowering the distance movement. Therefore, as shown in Figure 10 , Form-finding 1 held by the head socket 2 by the head socket 60 can be driven by the S lock 52 of the injection core filling 50. Moreover, in this bitter case, the lock 52 that shoots the core game 50 does not need to be completely unlocked from the open end of the search type I, at least between the S lock 52 and the inner wall of the ball type 1, there is a gap for air to enter. However, the fungus drag is still to set the descending stroke of the head fixing plate 64, that is, the de-constructing stroke of the core lock 52 (the length L shown in the figure 0), set at 50 (ao

Next, a description will be given of the horizontal open-distance moving part 100. This blocking open-distance moving part 100 has, for example, a second cylinder 102 as shown in Figs. 1 and 8. As shown in FIG. 11, the second cylinder 102 means that the second pillar 104a is fixed to the second cylinder fixing plate 104b supported by the first lifting plate 86. Therefore, the first re-licensing board 86 can use the first cylinder 82 to re-licens the license, and the second cylinder 102 is also driven by lifting. Longer than the second cylinder 102, the second lifting plate 106 is moved by the second movable continuous pinch l02a at a different interval, and the second lifting plate 106o is rolled and opened. The lower end of the visual chess opening convex H108 forms a supply shape, which is equivalent to the exchange holes 64d provided in the partition plates 64a, 64b of the fixed neck plate 64. Therefore, when the second cylinder 102 is moved, the visual chess is opened and convex and 108 is lowered to move, and its front end arch can be inserted into each beam hole 64d of the head fixing root 64, so a pair of partition plates 64a, 64b can be used. Open precession. Therefore, a pair of openings 62 fixed to the pair of partition plates 64a, 64b respectively_a, 62b is the open drive, and the loose type 1 can be taken out from the head socket by pressing 60. In the wooden embodiment, the driving timing of the second cylinder 102 is set after the first cylinder 82 is indeed activated.

Next, the operation of the bulk forming station 10 in the apparatus of the above-mentioned embodiment will be described.

<u style="single">The injection is refracted by the shape part 14 to form the connection</u>

Utilize the cylinder 28 for pitch movement to lower the upper seat filling 22 to move it, and the injection core filling 50 and the neck socket filling 60 can fill the injection socket 42 with a pitch movement. After setting the squeezing state shown in solid 4, replace the injection device 12 in the forward and rotating drive, then the injection molding material of bulk 1, such as embedded ethyl terephthalate (PET), that is, it is cleaned by heat. The mouth 40 is filled in the sockets specified by 42, 50, and 60 of the gold peripherals, and the ball-shaped l injection molding is carried out.

<u style="single">The cooling step of Sheshan forming part I4</u>

The injection socket press 42, injection core filling 50 and head filling 60 can be filled with cold coal, such as room temperature water, to directly cool the street fingers filled in the business.

<u style="single">mm out of mm1Ldmm quotient according to 42m cast first</u>

Press the cylinder 28 for starting, press the upper field button 22 to rise and start, press the 11th solid opening state, shoot the magic fill 50 and the head quotient button 60 to move upward relative to the shot nest chess 42. At this time, the neck 2 of the spot type 1 forms a bottom gap with respect to the disengagement direction, and the injection molding-finding 1 is held on the side of the injection S filler 50 and the head socket 60, and is discharged from the injection socket horizontal 42.

At the beginning of the uncoupling of the injection molding part 14, the sugar can be fully described earlier than when the decoupling started in the conventional art. In other words, in the prototype 1 of the injection molding part 14, the cooling time can be shortened. In this way, even if the injection socket 42 is removed from the spot type 1, and the core stroke is 50 bends, the core lock 52 can increase the pressure. Maintain the state of inserting the search type 1, so as to prevent the hot wire of the intermittent type 1 Award shape. Therefore, the pure type 1 unfilling temperature in the injection molding part 14 is to form a surface layer on the surface of the prototype 1, and the shape can be maintained after the injection nest is unfilled. It is better, and the conventional unfilling temperature can be used. Even with such a high stripping temperature, the type finding 1 shrinks on the close side of the lock 52 of the injection mandrel 50 due to cooling, and it can be counted to expand from the injection socket filling 42, so that type finding 1 does not occur. Because the core lock 52 is not pulled out in the injection molding part 14, even if the release 1 is demolded at a high demolding temperature, the lower end of the mold 1 together with the 8 lock 52 will be bent.

In addition, the ejection core press 50 and the head fill 60 to fill the ejection socket very 42 and the type finding 1 is in a fully filled state, and the recovery bullet 74 is used to maintain the 8 fixed plates 56 and the head seat plate 65 in a tightly connected state. . The state of the injection S data 50 and the head expansion 60 of the field, refers to the subsequent prototype l transport step, and waits until the bulk take-out part 16 releases the injection S expansion 50 to overdrive. Therefore, during the filling state of the stacking injection core press 50 and the socket socket 60, the type 1 can be cooled.

The form-finding 1 is embedded and fed from the injection molding part 14 to the form-finding extraction part 16. It uses the distance of the rotary actuator 32 to rotate the rotation range 30 of the first finger conveying part 180^'In the number of expansion steps of this type 1, the cold expansion of the injection core filling 50 and the head socket width 60 planting ring can be used for the cooling of the fiber field stacking type 1.

Among them, when the prototype 1 is deviated at high temperature, due to insufficient cooling, it contains crystallization sites, resulting in an unknown defect on the wall of the group 1, especially when using PET to form a transparent container, which becomes a fatal defect. The g-connection of the aluminum alloy according to the present invention, the crystallization and non-condensation of the group type 1 accompanied by insufficient cooling, is more problematic on the inner wall side of the type 1. It is sold because of the filling of the terminal surface of the Jin Gu chess. There are less school on the inner wall side of the type 1, and the inner wall is more insufficiently cooled than the outer wall. In the conventional injection molding part, the injection socket structure 42 and the injection S are filled 50: when disconnected from the loose type 1. The heat dissipation surface of the inner wall side of the spot type 1 is less, and the inside of the search type 1 contains heat, so that the inside The wall side is more undercooled than the outer wall.

In this example of dragging, even when the mold-finding 1 is unfilled at a higher temperature in the injection molding part 14, in the subsequent feeding step, the left injection mold 50 and the neck socket 60 can be injected to increase the spot pattern 1. cool down. Especially by using the S lock 52 of the injection core to press 50, it can be added back to cool the inner wall of the group type l, ensuring that the female bears prevent insufficient cooling and cause crystallization and unevenness. The head is 2 thick, the heat capacity is straight and it is easy to crystallize, and the head socket is 60 to cool it, which can prevent crystallization_'

<u style="single">Find the type-finding cooling spots in the release section 16</u>

Even if the in-position type 1 transports the person-finding and taking out part 16, and the shots 50 and the remnant socket filling 60 are maintained in the position-to-position type 1, the type-finding 1 can still be cooled in the same way as the above-mentioned transportation step. At this time, in the injection molding part 14, even if the seat cylinder 28 is driven to move the upper mold plate 22 for the next spot injection molding, the above-mentioned distance filling state can be maintained in the mold extraction part 16, and the search is increased. Type 1 cooling.

<u style="single">The head quotient increased by 60 from the ejection x finger of 50 off the increased square spot</u>

The bulk type 1 is cooled by the core lock 52 of the injection core filling 50. In order to prevent the crystallization caused by insufficient cooling of the inner wall of the type 1 and prevent the deformation of the injection prototype 1, it is advisable to have a sufficient cooling time, and vice versa. When the core lock 52 is used for moderate cooling, it is difficult to drive the core lock 52 out. At this time, in the group-type take-out part 16, the core filling 50 is relatively driven off from the beach-type 1 in the past. Todays towing order can fill 60 to the head socket of the type-finding 1, which is relative to the shooting distance of 50.

The demolding distance movement of the head simple filling 60 is to forcefully seal the fixed plate 56 of the main part by using the movement of the reversing principle to hold the fixed plate 56 to stack the head seat plate 65 in the close state, and use the head stripping distance moving part 80 to lower the distance. verb: move. When the first cylinder 82 of the head moving part 80 is driven, the first movable joint 82a, the first lifting waste 86, the drag distance 88 and the driven distance 68 are used as the applied distance power, as shown in the sixth As shown in Fig. 10 and Fig. 10, the head fixing plate 64 can be applied to the head seat 65 to drive it down. At this time, the head 2 of the phosphorus type 1 is held by the head socket horizontal 60, and the type-finding 1 also moves with the head fixing plate 64 and the head socket 60. Therefore, using the relative displacement of the head chess 60 and the ejection core dummy 50, the ejection core 50 can be deconstructed from the spot type 1.

The ejection of the core filling 50 relative to the unfilling stroke of this type finding 1, in a well-known manner, in order to send back the type finding l inspection, the core lock 52 is not completely unfilled from the open end of the prototype 1, at least in the core lock 52 and It is advisable to form a gap where air can enter between the inner walls of type 1. Therefore, the de-filling process of the injection core filler 50 depends on the push-pull angle formed by the core lock 52 and the inner wall of the prototype 1. The larger the push-pull angle, the smaller the de-construction balance process should be. In this way, because the ejection stroke of the injection core 50 can be shortened, the installation height of the first cylinder 82 can be reduced, and the initial height of the injection molding device can be reduced, which is advantageous in terms of device connection and installation.

<u style="single">Left fold, 1R gnaw pull type 1 for light emission</u>

Look for the head of the type 1. Because the head socket 60 is formed by holding the molds 62a and 62b on the side, it will be driven out of the head socket 60, and the prototype can be taken out. Therefore, the horizontal opening of the distance movement The second cylinder 102 of the part 100 is pitch-moving. Compared with the second cylinder 102, it is more powerful than the second cylinder 102. The second piston pinches 102a and the second lifting plate 106 is passed to the mold opening convex cadmium 108. The lowering distance of the spacer opening convex wax 108, as shown in Figure 11, is the front end Insert into the control hole 64d formed by a pair of partition plates 64a, 64b, and the opening drive of the partition plates 64a, 64b is to open a pair of partitions 62a, 62bo._a62b, if the head 2 of the prototype 1 moves in close contact, as long as the S lock 52 of the injection core filling 50 stays in the position type 1, the lateral movement of the search type 1 can be restricted, and the use type 1 does fall down .

In addition, in the state before the mold opening convex station 108 is lowered and moved, in order to avoid the dry pressing of the rotating scale 30 during the rotation and precession, the front end must be stopped within the thickness of the upper seat template 22. On the other hand, by using this step to open the convex lock 108 to open the moving head fixing plate 64, when the position of the rotating connection 30 is opened, the descending distance of the opening convex lock 108 is lengthened. In the case of the fungus, the distance will be here. The second cylinder 102 of the opening protrusion 108 is fixed to the first lifting plate 86 that uses the first cylinder 82 to move. Before the opening of the protrusion and the lock 108 are moved, Lowering the distance of another lifting waste 86 can shorten the substantial descending range of the apparently open convex cadmium 108. This vehicle can also reduce the installation height of the second cylinder 102, increase the height according to the finger of the injection molding machine, and provide a device that is advantageous in terms of general connection and installation.

After this group type 1 take-out step is completed, the first and second cylinders 82 and 102 are in the initial state. As a result, the head seat 65 is closely attached to the fixed plate 56 of the S part by the 74th recovery projectile._a3 can provide the value of injection core horizontal 50 and head cyanide. Fill 60 pressure filling state, ready for the next injection molding.

The cooling and de-filling in the above-mentioned connecting mold take-out part 16 will result in the injection molding part 14 before the next scattered injection molding is completed, that is, within the timing of the injection molding of the ring. The cooling time of the spot type 1 depends on the thickness of the tube of the type 1 part. For the bulk type 1 to be thick, the cooling time must be long. In the case of parallel cargo dragging, the investigation of the cooling time and the adjustment of the cooling time in the injection molding section 14 can be done by setting the timing of the ejection of the shot chess 50 in the position-type extraction section 16. Therefore, even if the release temperature of the injection molding part 14 is increased and the injection molding ring is shortened, because the cooling time is easy to adjust, a general-purpose scattered injection molding station can be provided.

After the injection molding of the prototype l of the injection molding part 14 is completed, the application and shot 30 are rotated by the rotary actuator 32 by 180°, which is formed by the injection core filling 50 and the neck socket 60 sealing the two parts l4 and l6. In this cargo towing example, the rotary actuator 32 is constituted by a reversible delivery mechanism that changes the direction of rotation and conveying each time. Therefore, take over the shooting magic 50 and the neck socket 60 that are rotating and conveying, and connect the cooling pipe for the refrigerant ring. Therefore, the connection of the cooling pipe to the gold and business horizontal can be carried out without a rotary joint, and the structure is not complicated.

At this time, Push Type 1 is trapped in uniform temperature or proper temperature distribution based on the above reasons, so a bottle of the required thickness can be formed. It can also prevent daily chemical crystallization of the bottle, and obtain a high-transparency bottle. The invention is not limited to the above-mentioned blow molding method of hot blanks. Once the bulk l is piled back to room temperature, and then heated to blow out, any cold blank blow molding method is of course also applicable. In this case, it also has the effect of shortening the timing of the prototype injection molding ring.

Secondly, about the composition and operation of the transfer god 200, please refer to the Guzheng drawing, the 12th to 14th drawings and the 21st to 22nd drawings for explanation. The 12th to the 15th drawings are not equivalent to the first solid eye towing device. , But it shows the mechanism that is opposite to the embodiment of Figure 21_.Figure 21 shows the above simultaneous forming of H and n respectively H: 6 and_n: In the case of 2, therefore, each mechanism of the transfer station 200 shown in Figures 12 and 15 can be transferred at the same time_n: 2 spot type 1. While the n:1 type finding 1 is the same as the case of n:2, except that the transfer pitch described later remains unchanged.

This transfer station 200 greatly includes a receiving and lowering mechanism 210 that takes the spot 1 from the extraction part 16 of the spot forming station 10 and accepts the sag, and Tango reverses the spot 1 and transfers it to the receiving part 304 of the blow-out forming station 300.

Figures 12 and 13 respectively show the rising position and the sag position of the sinking projection structure 210. The descending ladder structure 210 has a bottom holding part 214 for holding the bottom of the type 1 and a supporting environment 2 existing at the lower end of the head 2 of the supporting group 1._aThe holding portion 218 below the head. The bottom holding portion 214 is fixed to the distance 212a of the first lifting distance moving device 212 formed of a cylinder or the like, and can be raised and lowered between the rising position shown in FIG. 12 and the sinking position shown in FIG. 13. This lifting stroke b is shown in the circle.

On the other hand, the lower head holding portion 218 can be lifted and lowered together with the bottom holding portion 214, and only the horizontal movement stroke shown in Figure 4_aCan be moved with water)_#Therefore, the first sliding portion 220 is configured to be able to slide freely along the rail 222. Therefore, the first sliding part 220 can use the first retreat distance moving device 216 formed by the gas field, etc._a, Move in the direction of water. The lower neck holding portion 218 has a small diameter shaft portion 218 in the lower area_a, The upper area has a large-diameter curved portion 218b, and the small-diameter sleeve portion 218a penetrates the stop member 220 fixed to the first sliding portion 220_a. Therefore, the lower end of the small diameter cocoon milk 218a protruding downward from the stop member 220a is fixedly provided with a flange 218c. In addition, the small-diameter shaft portion 218 protruding upward from the bottom holding portion 214_a, It is equipped with bullet 218d. Because the bi-pump 218d is arranged between the bottom holding part 214 and the great warp part 218b, the peripheral bottom holding part 214 rises, and the big Jing curving part 218b, that is, the long shenfeng 218d is seated upward, and the holding part 218 under the head can be raised. . In addition, when the first stack retractor 216 moves, it transmits the curved parts 218a, 218b to the first sliding part 220, which is the horizontal distance power, so that the holding part 218 under the head can be slid in the horizontal direction. a As shown in Figure 4.

Next, refer to Figure 4, Figure 12 and Figure 13 to explain the function of this bearing lowering mechanism 2f0. In the take-out part 16 of the ball forming station 10, before the head business chess 60 is opened to move, the bottom holding part 214 and the lower head holding part 218 are arranged at the position shown in the figure 12_.In the state shown in FIG. 12, the upper limit position of the lower neck holding portion 218 is determined by the position where the flange 218c at the lower end hits the stopper 220a. The bottom holding part 214 is after the holding part 218 under the neck reaches its upper limit position, it presses the bullet 218d into the line and then stops at the rising position. At this time, the lower head holding portion 218 is set at the position directly below the support ring 2a of the loose type 1, and then retracts to the right side of Figure 4 and Figure 12, and then the head socket 60 is opened. The distance is moved, the shape is 1 direction, and the bottom part 3 is received by the bottom holding part 214. At this time, like the twelfth solid one, the loose type 1 is not completely dephosphorized core lock 52, and the core lock 52 is partially inserted in its original state to maintain the prototype 1 in an upright state.

Then, the first forward and backward driving device 216 is driven, and the lower part of the head 218 faces the left side of Figure 12, and only moves the distance a distance phosphorus (see 14 solid). Therefore, the lower neck holding part 218 is arranged in the prototype 1 Support to fill in the position directly below 2a,

Subsequently, the first lifting driving device 212 is assembled and drawn into its stroke 212a, and the bottom holding portion 214 starts to move downward. In this initial state of the sag movement, before the spring 218d elastically recovers, the lower neck holding portion 218 stops at its upper limit position. Therefore, in the initial state of the confirmation movement, the bottom holding portion 214 pulls away the bottom 3 of the prototype 1, on the other hand, look for the support ring 2 of the model 1._aThat is, it is set on the holding part 218 under the head. After blocking, the first re-resisting driving device 212 is then driven. In addition, the bottom holding part 214 and the lower holding part 218 of the milling part are connected to the form-finding 1 by using a member with low thermal conductivity, such as synthetic street fingers. The beach type 1 supporting the holding part 218 under the enlarged part is sent to the position shown in Fig. 13 from the fold down.

Next, the structure of the inverted transfer mechanism 230 will be described with reference to Fig. 4 and Figs. 13-15. This inverted transfer mechanism 230 and Figure 21 only blow out the forming part 310 at the same time to blow out n pieces: 2 corresponding, with two head holding mechanisms 232-. (See Figure 14). Each head holding machine_iThe structure 232t has a pair of heads. The holding member 234 can hold the head 2 of the bulk type 1, so it can be closed freely. The two neck holding mechanisms 232 are set on the support white 236 as shown in FIG._ao Therefore, the two-head holding mechanism 232 can lift and drag only the lifting and moving stroke as shown in Figure 4_e(See Figure 4). In order to facilitate the lifting and moving of the source, for example, two guide pinches 240 can be provided, which are guided by the guide 242 (see Figure 15).

The above-mentioned second lifting driving device 238 and the guide portion 242 are arranged on the second sliding portion 244 as shown in FIG. 15. Therefore, the second sliding part 244 is provided in the horizontal driving device 246, and can move along the arrangement direction of H, for example, four prototypes 1 that are simultaneously injection molded in the injection molding part 14. The horizontal distance device 246 can be, for example, a screw search 246_a, Make the second sliding part 244 horizontally move. Furthermore, the horizontal actuation device 246 is arranged on the third sliding portion 248, and the third sliding portion 248 is arranged on the second forward and retreat driving device 250, so that the forward and backward balance process of Fig. 4 can be moved forward and backward._co As shown in Figure 14, the stroke 250a of the second advancing and retreating device 250 is connected to the third sliding part 248o

In addition, an upside-down installation device 252 is provided to keep the two heads of the ladder structure 232 horizontally fired to assist in rotating 180. Compared with the 180. rotation stroke d of the inverted head moving device 252, as shown in Fig. 4. As a result, the spot type 1 with the head 2 upright in an upright state can be driven upside down so that the head 2 is upside down.

Secondly, the function of this reverse transfer mechanism 23o will be explained. As shown in FIG. 13, when the release 1 reaches its lowered position, the head holding mechanism 232 in the standby position shown in the string is connected to the head holding mechanism 232, which is driven by the reverse head moving device 252 to rotate 180°. In addition, the use of the head holding mechanism 232 Uchita's worm-closed distance moving mechanism, a pair of head holding members 234 can be found_：With the lock drive, the head 2 of the loose type 1 can be held by using the pair of head holding members 234. Then, perform the upside-down movement of the prototype 1. Prior to this, in order to prevent other members of the spot type 1 dry pole, the lower head holding part 218 was retreated from the state shown in Figure 13, and only the moving stroke a (see Figure 4) was used to retreat, and the third sliding part 248 was facing The left retraction moves only the stroke c (see Figure 4), so that the second head holding mechanism 232 moves to the left. After the gate, the prototype 1 is rotated 180 by the inverted distance moving device 252, and the prototype 1 reaches the position shown in the virtual entertainment in the 13th figure. Then, the second lifting drive device 238 is used to sink the two head holding cards according to 232. stroke_eAt a distance from the phosphor (see Figure 4), the form finding 1 can be placed on the conveying member 330 arranged on the receiving part 304 of the blow-out forming station 300. After the brake, open the neck holding mechanism 232 to move, and then move it longitudinally as shown in the figure._eAccording to the distance from the lateral movement stroke c, the head holding mechanism 232 is retracted from the prototype 1, and the standby position is set as shown in the virtual view of Fig. 13 in the case.

The above-mentioned transfer action is to simultaneously form n:2, as shown in Figure 21, drag the example device, that is, transfer n:2 prototype 1 at the same time. The transferred 2 spots l are transferred to the conveying button 330 at the second receiving position 260 shown in Figure 14. At this time, the pre-part holding and weighing mechanism 232 uses the bearing and descending mechanism 210 to bear the two spot 1 hour distance P2, The distance P3 is different from the time when the conveying member 330 is received. At this time, when the inlay type 1 is transferred, the spacing is changed by the spacing assembly driving device 254, which will be described in detail later. As shown in Fig. 1, n pieces are simultaneously formed: 1. For the embodiment device, the prototype 1 is at the second receiving position 260 shown in Fig. 14_LThe middle position of, is transferred to the conveying member 330. Therefore, whenever_： Shape H: one injection of 4 is completed, i.e., the transfer operation of the prototype 1 is repeated four times.

Next, referring to Figure 19 and Figure 20, the heating part 366 is described.

The heating part 306 is inside the heating box cover 350 which is commercialized, and uses the apparent radiation heat to heat the type-finding 1. As described above, in the wooden embodiment device, the search 1 is transported from the injection core 50 to the take-out part 16, and in the take-out part 16, the injection head 50 is de-formed from the spherical shape 1, and the search can be removed. Type 1 is fully cooled. Therefore, even with hot blanks, the embryonic form can be fully cooled to a lower temperature than the suitable temperature for blowing. At this time, the Kiru dragging device can heat the prototype 1 at the heating part 306 provided in the blow molding station 300 to a suitable temperature for blow molding.

Inside the heating box cover 350 of the heating part 306, there are first to fourth birch heaters with reversible configurations. 352a to 352d constitute the first heater_：The group is separated by 1 cocoon in the loose type. Each of the connecting heaters 352a to 352d may form, for example, a buckle external view heater, which extends in the bulk 1 conveying direction in the heating box cover 350. The first and second regular heaters 352a, 352b consolidate and condense the reflector 354_aFor the prototype 1, especially the vicinity of the bottom 3, use radiant heat to heat it. On the other hand, the third and fourth connecting heaters 352c and 352d consolidate the light-collecting reflector 354b, and heat the vicinity of the cylindrical portion 4 of the model 1 with spot heat. As shown in FIG. 19, in the beach-type 1 transportation route area, a reflecting plate 356 is arranged at a position opposite to the first to fourth connecting heaters 352a to 352d.

In addition, as shown in Figure 19, on both sides of the conveying path holding the prototype 1, the fifth and sixth regular heaters 352e and 352f are arranged to form a second heater group. The vertical height positions of the columnar heaters 352e and 352f are located opposite to the area near the head 2 of the prototype 1 extended and guided by the blow molding part 310. The heating areas of the fifth and sixth law-like heaters 352e and 352f are the area directly below the head 2 when the prototype 1 is in the upright state, and the lower joint portion lower area 4a.

The area 4a below the head is a shoulder area corresponding to the blow-out molded bottle 6. Therefore, when the prototype 1 is configured in the blow-out filling 378, the area below the head 4_aThat is, it is placed in the closest position to the blowhole surface. Therefore, the area below the neck 4_aThose with thick walls can easily lower the horizontal axis guide car, stacking the area below the head 4_aFully heated, it can be shaped into the required wall. Therefore, in the case of the fungus dragging in the area 4a and the opposite position under the head of the type finding 1, the fifth and sixth configuration heaters 352e and 352f are arranged. The device is closer to the area under the head 4aT

Inside the heating box cover 350 of the heating part 306, as shown in FIG. Since_/The rotation lock 348 of the rotating connection 358 and the conveying member 330 in the heating part 306 is only combined, so that when the rotation distance moving key 358 is actuated, the rotation lock 348 is the rotation, and the rotation force is borrowed from the cylinder. 342 transmission connection type 1, find type 1 namely rotary drive.

Therefore, when the spot type 1 is sent to the heating part 306, the bottom 3 and the tube part 4 of the bulk type 1 are respectively affected by the regular heaters 352a to 352e arranged on the one side of the conveying path and the reflecting plate 356 arranged on the other side. Radiation heat, at the same time, in the rotation of the type l, it receives approximately uniform apparent radiation heat in the solid circumferential direction, and it can be uniformly heated in the circumferential direction. Furthermore, the lower neck area 4 of the prototype 1_a, The fifth and sixth connecting heaters 352e and 352f arranged on both sides of the transport path close to the bulk f are fully heated, and due to the rotation of the bulk 1, it can be heated more evenly in the solid circumferential direction.

Here, as shown in FIG. 20, the conveying direction of the spot type 1 is set to A, and the rotation start 358 is at the position only with the rotation lock wheel 348 of the conveying member 330. The proceeding direction is B, which is opposite to the A direction. The reason is as follows.

That is, when the conveying hanger 322 and the rotation distance movable lock 358 move together in the same A direction with the same continuous degree, the relative positions of the self-reversing lock 348 and the rotation distance movable lock 358 on the side of the conveying member 330 are not rewarded, and the group type l It does not rotate at all. Even if only the conveying speed of the conveying rotation 322 and the rotation distance moving key 358 are modified, depending on the speed, the rotation of the prototype 1 will become extreme or reverse. In this case, the rotation drive 558 uses the conveying money 522 to increase the speed. It will not happen during rotation. It is usually said that the plateau rotation is in the torque brake system. It is not suitable to connect type 1 when rotating at high speed.^'Containing boundary music, when subjected to strong force for a short time, the interlude is greater, which becomes the reason for the partial temperature during heating, and has an unfavorable effect on the thickness distribution of the bottle 6.

Therefore, according to the embodiment shown in Figure 20, when the travel direction of the conveying lock 322 and the rotation distance movable lock 358 are opposite to each other, the bulk type 1 is drawn in the direction A, and its rotation direction is fixed in the direction of the arrow C of the fixed 20. , You can solve the above problems. In addition, when the ball type 1 is being transported, the rotation degree of the prototype 1 at the stop position can be gradually increased.

Furthermore, the prototype 1 in the wooden embodiment is between the heating zones located inside the heating box cover 350, and the prototype 1 can be set to an integer number of rotations. Type-finding 1 is located between the heating zones. Take the fungus drag example 1, as shown in Figure 20, that is, the movement time of each distance from the phosphorus L1, L2, L3 (L1+L2+L3: heating zone length L). Figure 26 shows the two positions between stops. L1 represents the distance between the insert type 1 sent into the heating zone and the first stop position, L2 represents the distance between the two stop positions, and L3 is the conveyance distance from the second stop position to the sending out of the heating zone. . In this example, the delivery time and the stop time are set at approximately the edge of the bulk 1 mesh revolving time, so that the spot type 1 solid circumference direction can be subject to the same sentence on both sides of the ball 1 transportation path. Heat can prevent the temperature variation of the bulk type 1 in the circumferential direction.

Furthermore, according to the water drag example, the heating effect of the bulk type 1 in the heating part 306 can make the temperature difference between the inner wall and the outer wall of the bulk type 1 fully dragged before this. For example, the stone-finding forming station 10 uses the injection S fan 50 to fully cool the spot 1 from the inner wall side. Therefore, the 16_：The degraded T taken out is in a state where the temperature of the inner wall is low and the temperature of the outer wall is high. However, this connection type 1 is in the case of the hot blank method or the requested general method device, during the Cheng Duanpu conveying period, it is not the Jing conveying heating part, but the conveying function of the conveying station 2w and the segmented conveying function of the conveying member 330. After that, it is sent into the heating part 306. Therefore, the spot type 1 is sent into the heating part 6 after being released from the mold and after a cooling time longer than any stage. Therefore, the temperature difference between the inner and outer walls of the bulk type 1 can be fully residual. When there is no temperature difference between the inner and outer walls, although the device is the same as any cold blank method or the requested two-stage method, the stack is compared with this device. In the Taiqi embodiment, the blank material 1 that maintains the injection molding heat can be blown into a bottle 6. Therefore, the drill has less heating energy for dragging, which can save energy beforehand.

However, according to the wooden embodiment, the bulk type l cooled to a temperature lower than the temperature suitable for blow molding (the stack is still high enough) is heated and empty, which can improve the bulk temperature stability of each molding finger filling, and at the same time inject The formed complex pattern type l is divided into the different temperature variations during blow molding, which can also be reduced. In addition, in the jellyfish embodiment device, a certain distance can be maintained by using the second ring conveying part 302 to send the type 1 conveying distance. In contrast, in the well-known cold blank method or the two-stage method of forming, the conveying distance when the heating part is heated for the search is small, and the conveying distance when the conveying person blows out of the forming part is large. The mold must be reheated to reflect the appropriate temperature for forming, and the prototype that can be introduced into the heating section can achieve the maximum shooting effect, which can save the space of the device. It must be larger than the maximum width of the minimum molded product. In addition, the bulk shape before sending out the molding part and the shape finding after sending it out must be outside the reflection pressure filling device of the reflection molding part._-spare. Thus, in_：Xi is like a section of the party. For a high-speed forming machine, the conveying distance must be changed in the middle, which complicates the device.

In the opposite position, the wood embodiment device maintains the state of injection molding heat in the injection molding part 14, and the bottle is blown and molded from the beach type 1, and the heat energy to be heated in the heating part 306 is less than that of the two-stage method. Therefore, even if the number of bulk molds arranged in the heating section 306 increases, the company commander can reheat the mold-finding 1 to a suitable temperature for blowing, and it is not necessary to change the conveying pitch in the middle.

<u style="single">Special Machine Department 308</u>

As shown in FIG. 1, in the middle of the conveying path between the heating part 306 and the blow-out forming part 310, the special machine part 308 ensures that the prototype 1 stops once in the normal conveying sequence in which the interval movement is performed. With this spare part 308, it can be connected to the temperature distribution of the synthetic gang finger dispersion type 1 with poor heat conduction column. In the water retention device, as in the heating of the heating part 306, the heat sealing group type 1 heating by the finger radiation on the outer wall surface is used. Therefore, the visibility of the inner wall of the bulk type 1 is lowered by the temperature of the outer wall. In the Kime dragging device, after the heating part 306 sends out the searcher 1, it is sent to the blow-out forming part 310, and the searcher 1 stops at the standby part 308 at least. Once, it can be connected to the temperature difference between the inner and outer walls, so that the reflection and formability of the bottle 6 can be constant. .

During the temperature connection time of the standby part 308, the temperature of the type 1 can be actively reduced. When the standby part 308 actively adjusts the temperature of the type-finding 1, the obtained temperature distribution is that the bulk type 1 cannot be connected by only one heating of the heating part 306.

The temperature regulating member arranged in the standby part 308, as shown in Figure 23, for example, find.: Insert under the type 1 into the inside of the type 1, and in the temperature regulating area S bowl, as the inner wall side of the temperature regulation The temperature-regulating core part 400 of this temperature-regulating core part 400 has a first temperature-regulating core part 402, which faces the area under the head of the bulk type 1 from its wall side: 4_aIn addition, the temperature adjustment core 400 has a second temperature adjustment core 404, and can adjust the temperature of the cylindrical portion 4 other than the pre-part lower region 4a. According to the above, the area under the head 4_aThe temperature must be adjusted to be higher than other areas. As shown in Figure 23, the diameter of the first temperature-regulating portion 402 is larger than the second temperature-regulating core portion 404. It is also possible to coat a layer of material on the first temperature-regulating core 402, which can radiate heat data of a wavelength that is easily absorbed by a shaped fat material (such as PET).

As shown in Figure 24, the temperature control member can be used with a slightly warm poison 410 that is arranged around the fixed cylinder part of the type 1. 414a, 414d, each of the blocks 414a-414d has an independent temperature regulating flow finger passage 416, which independently controls the temperature of each zone. The temperature regulating cover 410 can be equipped with a pressed type 1, and the phased temperature distribution can be accurately obtained in the loose axial direction. Therefore, the area under the head can be increased by 4_aTemperature, and lower the bottom 3 temperature. As shown in the 24th solid, the air is introduced from the direction of arrow 420 in the search 1 and applied in the patch 1, and the outer wall of the scattered type 1 and the block 414_a~414d touch, you can adjust the temperature'

In addition, this kind of temperature-regulating component can also be located at one or more places along the circumference of the shape-finding 1, extending along the axial direction of the loose type 1 and trapping the temperature distribution of the prototype 1 along the circumference. For example, as shown in FIG. 25, on both sides of the bulk type 1, for example, a pair of cooling members 430 are arranged along the axial direction of the prototype 1, and the cylinder 432 can be used to contact the side wall of the cylinder of the bulk type 1. In this way, the temperature distribution of the prototype 1 can be provided along the circumference, as shown in Fig. 26, which can sufficiently ensure the thickness of the flat bottle 6 in the region with high horizontal axis elongation. This measure is not limited to flat containers, such as angled containers can also be applied. When the temperature distribution of the bulk type 1 is distributed along the circumference, it is not limited to contact with the cooling member, and it can also be arranged near the heating unit.

<u style="single">Mountain m forming part 310</u>

The reflection forming part 310 has two blowing fixed types 370 on both sides of the conveying path of the clamping prototype 1, and is fixed on the machine table 8. As shown in Figure 4, between the two blowing fixed connections 370, for example, the four support process 372' can be connected. Therefore, between the blowing fixed sugar 370, there is a two blowing pressure horizontal connection 374, which can be along the four press process 372. Move horizontally. The two blowing pressure horizontal strokes 374 can use the reflection pressure mechanism 376, such as a hydraulic piston, which is arranged on the blowing fixed disk 370, to move the wire on both sides of the vertical line.

The two blowing out makes the sugar filling 374 fixed on the one that constitutes the blowing out nest mold 378, the pair of road troubles 378_a, 378b. Taking the embodiment device shown in Figure I, due to simultaneous forming_nA: 1. Therefore, a pair of partitions 378a and 378b form a bottle socket. As shown in Figure 2f, both of the examples are shown. Because of the simultaneous formation of n-direction: 2, placed on a pair of partitions 378_a, 378b formed the second bottle quotient.

At the middle position of the upper second chord 372, a fixed cylinder pole 380 is fixed, and the bottom transverse distance moving cylinder 382 is approximately doubled here. The bottom horizontal distance moving cylinder 382 is used for the lifting distance moving bottom filling 384. In the wooden embodiment, the prototype 1 in the inverted state is blown out to form the bottle 6, and the bottom cross 384 can be prematurely sinked above the form-finding 1.

According to this example, in the injection molding section 14 of the prototype molding station 10, H:4 prototypes can be simultaneously molded to improve production efficiency. At the same time, in the blow molding section 3l0, n: 1 The prototype 1 is formed into a bottle 6, and the operation rate of blowing out the nest mold 378 can be improved. The number of nests that Jiayin Jinma fills 378 is actually blown out, which can reduce the cost of metal film for consumables. In addition, according to the wooden embodiment device, after the prototype forming station 10 is sufficiently cooled, the prototype 1 is released, and then the temperature difference between the inner and outer walls of the prototype 1 is relaxed. The prototype 1 maintains the uniformity of heat and straight temperature distribution, and especially improves the stability of the reflection forming.

<u style="single">Bottle take-out part 312</u>

In the delivery path of the conveying member 330 conveyed by the second circulating conveying part 302, between the blow-out forming part 310 and the receiving part 304, a bottle take-out part 312 is arranged, as shown in Figures 1 and 4.^’As shown in the figure, this bottle take-out portion 312 can adopt a neck holding profile 390, which has the same structure as the neck holding line 232 used in the inverted transfer mechanism 230, for example. The head holding card structure 390 uses a pair of holding members to hold the neck of a bottle 6 in an inverted state. As shown in Fig. 3 and Fig. 4, there is a lifting distance moving device 392 that drives the neck holding mechanism 39o by lifting and sinking, and the neck holding mechanism 390 is turned upside down and rotated at an angle of 180^'The inverted drive device 394. The head holding mechanism 390 is raised by the lifting distance moving device 392, and the neck of the bottle 6 is also disengaged from the upper side by the conveying lock 346 of the conveying member 330. Then, the neck holding mechanism 390 is rotated 180 by the inverted driving device 394^', The bottle 6 is standing upright on the side of the machine table 8. Then the clip that drives the neck holding mechanism is opened, and the bottle 6 is discharged out of the device.

<u style="single">Forming the same song H: 6" n: 2</u>

Figure 21 shows the number of simultaneous forming H and n connected to the f-plane value of the embodiment device set above, and the embodiment device shown in the 21st solid_iDifferent from the embodiment shown in Figure 1, the drill is as follows.

First, the blow-out forming part 310 is formed by simultaneously forming n:2 prototypes and simultaneously blowing and forming two bottles 6, so the blow-out nest mold 378 has two nests, arranged at a pitch P3. In addition, the arrangement pitch of the conveying members 330 conveyed and driven by the second circulating conveying part 302 is the same as the blow socket arrangement pitch P3 of the projection forming part 310. Furthermore, the number of transporting locks 522 that constitute the second ring transporting portion 302 and the number of fixed transporting members 330 is a multiple of that of the embodiment device shown in Figure 1, that is, 20. Also, in the heating section 306, there is a number of secondary blow molding prototypes, namely 2X_n: 4 prototypes 1 stop. In the spare part 308, there is one blow molding_n: 2 bulk spares_.The conveying sugar 322 and conveying member 330 used in the embodiment device shown in Fig. 21 are the same as the embodiment device shown in Fig. 1, except that the installation position and installation distance of the conveying member 330 to the conveying lock 322 are changed.

In the g-towing device shown in Figure 21, the projection forming part 310 can be simultaneously formed at the transfer station 200_nPieces: 2 spot 1 transfer'Therefore, there must be the transfer pitch replacement action described in the 22nd solid'. In the figure, the spot forming station 10 injection molding section 14 simultaneously injection-molded six scattered 1s, respectively. Bulk 1_aShown in 1f. The state shown in the first row on the right in FIG. 22 shows the arrangement pitch of the spot patterns 1 that are injection molded at the bulk molding station 10. At this time, the arrangement pitch of each prototype 1 is the same as the arrangement pitch P1 of the core 52 of the injection molding part 14. The second row state of FIG. 22 shows the state before the inverted transfer mechanism 230 of the transfer station 200 accepts the release l. At this time, the type finding 1 arrangement pitch is also P1. The third row in FIG. 22 shows the state of receiving the Ertan type 1 at the receiving part 304 of the barking forming station 300. The transfer of the two mat type 1 is carried out by using a pair of head holding members 234 of the second block shown in FIG. same.

At the transfer station 20o, a pair of head holding members 234 of two blocks is used to transfer the loose type l ladder, and the first and fourth release types 1a, 1d' are first held, that is, to skip the two block type 1b, 1_cIn the state of, the two-spray type 1a and 1d are maintained. Therefore, at this time, the arrangement pitch of the pre-holding member 234 is P2:3XP1. As a result, the pitch P2 becomes P3, and the pitch motion of the pitch motion device 254 as shown in Fig. 14 is used to convert the arrangement pitch of the two head holding mechanism 232. The same applies to the second and fifth prototypes 1b. , Le transfer, and then transfer the third and sixth bulk t at the same time_c, 1f, and the transfer operation of the six inserts 1 that were injection molded at the same time is completed.

Simultaneous forming number H: 4,_n: At 2 o'clock, the transfer action of the moving station 300 is the reward-change interval, which is sent from the interval P2: 2XP1 to P3. It is advisable to skip a loose shape while maintaining the second prototype.

Taking the embodiment device shown in Figure 21, the number of simultaneous forming H and_nThe ratio (H/n): 3. According to the research of the inventor of Mu, for a commonly used medium-sized container with a narrow mouth of about 1 to 3 liters (the second diameter of the head is about 28-38mn), it can be known that the ratio of the number of simultaneous forming H and n is best set at H :n:3:1. The reason is as follows. The size of the beach for the forming of commonly used medium-sized containers depends on the purpose. The elongation factor necessary for the elongation characteristics of the polyethylene terephthalate (PET) resin and the elongation factor necessary for the stability of the forming determine the size of the bulk. Due to the use of various containers, there is a certain degree of discrepancy. According to researches such as the invention of wood, it can be seen that the maximum thickness of the tube 4 of the prototype 1 used in medium-sized containers is about 3,0~4.0mn.

Generally speaking, the blow molding cycle time required by the blow molding machine for blow molding (in the blow molding section 310, the time required from the delivery of prototype 1 to the delivery of prototype 1) is about 3.6 to 4.0 seconds.

The wood embodiment is deviated from the injection line 42, and is connected to the injection core filling 50 to cool the prototype 1 and then blow it out. These commonly used medium molding molding takes time. Compared with the conventional injection extension blow molding machine, it can be It can be shortened by about 3/4, and it can be seen that the injection molding cycle time is about 10~15 seconds.

Therefore, set the specific injection molding cycle time (about 10-15 seconds) as T1, and the blowing molding ring time (3,6-4.0 seconds) as T2, which is about T1:T2:3:1. When the common medium-sized container is formed with good efficiency , Please set the above ratio to find the best H and n at the same time. In contrast, when forming a large container from a thicker prototype, the injection molding cycle time is about 16%, which can be set at H:_n:4:1 etc. In addition, when forming small containers from a layer prototype, the injection molding cycle time is shortened, and H:n:4:2 can be set.

In this way, once setting H/n: 3, the injection molding cycle and blow molding cycle suitable for the molding of medium-sized containers with the largest market demand can be set, and the reflection molding machine with little molding cycle waste can be realized.

<u style="single">The discharge line connection in the embryonic residual baking coating</u>

In the wood inverting device, as shown in Figs. 2 and 3, in the transfer station 200 arrangement area of the machine 8, an opening forms a prototype knot opening 8a. The prototype drop port 8a communicates with the said chute 8b inside the machine table 8, and this chute 8b communicates with the bulk discharge port 8c opened on the side of the machine table 8.

In this blow-out forming method of hot blank material, the bulk forming station 10 is connected to the formed prototype 1, and various conveying situations occur in the blow-out forming station 300. For example, when the entire projection molding machine is modified, it is necessary to prevent the defective prototype 1 from being supplied to the projection molding station 300 until the injection molding characteristics of the prototype 1 are stabilized. 300 operation, non-stop prototype forming station 10, connect the prototype 1 to form. Since there are various heating parts in the prototype forming station 10, once the power is cut off, the start-up time is quite time-consuming.

The wooden embodiment connects the injection-molded prototype 1 at the prototype forming station 10, and passes through the above-mentioned lower port 8a, chute 8b, and discharge port 8 before the transfer station 200 transfers to the blow-out forming station 300_c, Discharge on the side of machine 8. The ejection action of this prototype 1 can also be, for example, a pair of head holding cards 234 of the left-reverse transfer mechanism 230 holding the prototype 1, and then an inversion action of 180° can be performed, and the prototype 1 can be moved horizontally to a selected position, for example. So far, set the drop port 8 that opens on the top of the machine 8_aAt the opposite position, the holding state of the neck holding member 234 is then released.

The sequence control mode of the Taimu drag example is to set the bottle forming horizontal type in which the bulk 1 is transferred to the blow molding station 300 for blow molding into the bottle 6, and the shape finding and forming operation horizontal mode that does not transfer the prototype 1 to the blow molding station 300 Mode. The two horizontal modes are automatically switched when the detector detects abnormal conditions, or the operator can switch manually with a manual switch to switch from the normal bottle forming operation to the group forming operation mode.^'. When switching to the prototype molding operation pseudo-type, the operation at the transfer station 200 is an operation that guides the prototype 1 to the above-mentioned drop port 8a. Switching, and the lock type 1 is prohibited from being transferred to the blow molding station 30n side.

In addition, the great invention is not limited to the above-mentioned embodiments, but various alternative embodiments are available within the scope of the summary of the invention.

The above example of tea dragging uses the rotary joint 30 to transport the injection core 50 and the head socket 60. For example, when the shape of the head 2 does not form a bottom hole relative to the unfilling direction, the head socket 60 does not need to be used. In this case, after the injection molding part 14 has unfilled the injection card 42, the bulk 1 can be transported to the prototype take-out part 16 only by the injection core filling 50. The prototype 1 shrinks and deforms due to cooling, so as to be densely connected to the injection On the core lock 52 side of the core mold 50, the ejection of the conjunctiva 42 can be smoothly demolded. Even if the head 2 has no bottom, the mold 1 can be transported by the injection core 50.

At the mold-finding part 16, the ejection core mold 50 is detached from the prototype 1. For example, the following measures can be used. Function. In this case, in the beach-shaped take-out part 16, the prototype 1 is cooled by the injection core 50, and air is blown out by the core lock 52, and the prototype 1 can be dropped downward by using this air pressure.

According to the inventions in Sections 1 to 6 of the Tianqi Patent Section, in addition to shortening the injection molding cycle time and shortening the cycle time of the entire device, the stabilization of the cooling step can make the preservation heat of the release form stable and also Stabilize the thickness distribution of each container that is connected and blown out. Setting the number n of simultaneous blow molding to be less than the number H of simultaneous injection molding can reduce the degree of blown film and greatly reduce the metal filling cost of consumables. In addition, the H prototypes formed at the same time in the shortened forming cycle are blown out in several times, which can increase the operation rate of blowing out the nests and filling the n nests.

According to the invention of item 7 in the scope of patent application, the prototype is injected and formed in a prototype upright state, which can save space. Because the injection device can be directly configured on the machine, it becomes a stable configuration. In addition, in the blow-out forming section, the bulk is transported in an inverted state, and the head opening can be used to easily support the bulk. The extension distance, blow-out cores, etc. can be placed in the machine space below the prototype conveying path.

According to the inventions of items 8 and 9 in the scope of patent application, the injection molding ring time and the reflection molding cycle time required for the molding of medium-sized containers can be appropriately blown and molded with high efficiency.

According to the m-th invention from the patent application, the prototypes that are simultaneously formed in one blow molding cycle can be completely used for reflection molding in several times._lIt does not contain mixed blow molding with the prototype molded in the next injection molding cycle, so molding stability can be ensured.

According to the 11th invention in the scope of patent application, when the release in the heating part stops and when the conveying is moving, the loose type is surely rotated to prevent temperature unevenness.

According to the invention of item 12 of the scope of patent application, the phosphorus mold is discharged from the outside of the device before being transported to the blow-out forming section, which prevents poor mold finding due to unstable quality when the device is released, and blows out and forms into a container uselessly, and blows out the forming section. In case of abnormalities, even if the spot-shaped forming part is not stopped due to a power failure, and the operation of the device starting time is wasted, it can be divided.
