The transfer device 12 extends the rod 36 of the holding cylinder 34 of the component mounting portion 30 of the mounting portion 28, and mounts the jig 13 in the holding recess 33, that is, in the component mounting portion 30. Further, the transfer device 12 extends the rod of the slide cylinder 17 of the drop-off restricting portion 15 of the jig 13 and sandwiches the bus bar 3 and the terminal fitting 4 between the main body portion 14 and the moving holding plate 16. The bus bar 3 and the terminal fitting 4 are held by the jig 13.
Then, the transfer device 12 drives the robot arm 27 to position the mounting portion 28 between the molds 22 and 23 separated from each other as shown in FIG. At this time, of course, the component mounting portion 30 faces the fixed mold 22, and the molded product mounting portion 31 faces the moving mold 23. At this time, the box body 2 as it is molded is attached to the moving mold 23.
Then, as shown in FIG. 4, the robot arm 27 brings the molded product mounting portion 31 of the mounting portion 28 closer to the moving mold 23 in a state where the rods of the chuck cylinder 37, that is, the chuck members 38 are separated from each other. The box body 2 is positioned between the pair of chuck members 38. After that, as shown in FIG. 5, the rods of the chuck cylinders 37, that is, the chuck members 38 are brought close to each other, and the box body 2 is sandwiched between the pair of chuck members 38.
Then, as shown in FIG. 6, the transfer device 12 drives the robot arm 27, and while the box body 2 is sandwiched between the chuck members 38, the component mounting portion 30 of the mounting portion 28 is attached to the fixed mold 22. Get closer. After that, as shown in FIG. 7, the rod of the slide cylinder 17 of the jig 13 is reduced to stop sandwiching the bus bar 3 and the terminal fitting 4 between the main body portion 14 and the moving holding plate 16.
After that, the transfer device 12 reduces the rod 45 of the pressing cylinder 42 of the component pressing portion 32, and presses the bus bar 3 and the terminal fitting 4 toward the fixing die 22 with the pressing rod 47 of the pressing member 43. , As shown in FIG. 8, the bus bar 3 and the terminal fitting 4 are attached to the fixing mold 22. Then, as shown in FIG. 9, the transfer device 12 extends the rod 45 of the pressing cylinder 42 of the component pressing portion 32 to drive the robot arm 27 to position the mounting portion 28 on the carry-out unit 11. In the transfer device 12, the chuck members 38 of the chuck cylinder 37 are separated from each other, the box body 2 is placed on the carry-out unit 11, the rod 36 of the holding cylinder 34 is reduced, and a jig is placed on the carry-out unit 11. Place 13 on it.
In this way, the transfer device 12 mounts the jig 13 supplied from the second transport unit 9, and mounts (supplies) the bus bar 3 and the terminal fitting 4 attached to the jig 13 to the fixing mold 22. In addition, the jig 13 from which the bus bar 3 and the terminal fitting 4 have been removed and the box body 2 formed by the molds 22 and 23 are conveyed to the carry-out unit 11. Further, as described above, the transfer device 12 mounts the bus bar 3 and the terminal fitting 4 on the fixed mold 22, and removes the box body 2 formed by the molds 22 and 23 from the moving mold 23.
Further, before and after the transfer device 12 places the jig 13 and the box body 2 on the carry-out unit 11, the injection molding device 10 brings the moving mold 23 closer to the fixed mold 22 to open the cavity. After sealing, the cavity is filled with a plasticized synthetic resin. Then, in the injection molding apparatus 10, after the synthetic resin in the cavity is solidified and the box body 2 is molded, the mold 22 is pressed against the moving mold 23 by the extrusion pin 25. , 23 separate from each other. At this time, of course, the box body 2 is attached to the moving mold 23. In this way, the molded product manufacturing apparatus 5 described above molds the box body 2.
According to the present embodiment, since the component mounting portion 30 is provided on one surface 29a side of the main body portion 29 of the mounting portion 28 and the molded product mounting portion 31 is provided on the other surface 29b side, the mounting portion 28 is made of gold. By positioning between the molds 22 and 23, the bus bar 3 and terminal fitting 4 as parts for insert molding are attached to the fixed mold 22, and the box body 2 as a molded product is taken out from the moving mold 23. be able to. Therefore, the bus bar 3 and the terminal fitting 4 can be attached to the fixed mold 22, and the box body 2 can be taken out from the moving mold 23 in a continuous operation.
Further, since the mounting portion 28 mounts the bus bar 3 and the terminal fitting 4 on the fixing mold 22 and takes out the box body 2 from the moving mold 23, the mounting portion 28 moves to the fixing mold 22 of the bus bar 3 and the terminal fitting 4. It is not necessary to provide a transfer device for mounting the box body 2 and a transfer device for taking out the box body 2 from the moving mold 23, respectively.
Therefore, the work efficiency can be improved, and the cost and space required for the molded product manufacturing apparatus 5 can be suppressed.
Since the jig 13 is provided with a dropout restricting portion 15 for restricting the detachment of the bus bar 3 and the terminal fitting 4, and the component mounting portion 30 of the mounting portion 28 is provided with a jig holding portion 41 for holding the jig 13. When the mounting portion 28 is positioned between the molds 22 and 23, the jig 13 and the jig 13 from the mounting portion 28 may be positioned regardless of the posture in which the jig 13 to which the bus bar 3 and the terminal fitting 4 are mounted is positioned. It is possible to prevent the bus bar 3 and the terminal fitting 4 from falling off.
Further, since the mounting portion 28 includes a component pressing portion 32 that presses the bus bar 3 and the terminal fitting 4 from the jig 13 toward the fixed mold 22, the bus bar 3 and the terminal fitting 4 mounted on the jig 13 are provided. Can be securely attached to the fixed mold 22.
Therefore, even if the bus bar 3 and the terminal fitting 4 and the box body 2 can be mounted on the mounting portion 28 of one transfer device 12, the bus bar 3 and the terminal fitting 4 are not dropped and the bus bar 3 and the terminal fitting 4 are attached. It can be attached to the fixed mold 22. Therefore, the box body 2 can be reliably molded.
Since the molded product manufacturing apparatus 5 includes the transfer apparatus 12 described above, it is possible to improve work efficiency and reduce the cost and space required for installation.
In the above-described embodiment, the box body 2 of the electrical junction box in which the bus bar 3 and the terminal fitting 4 of the wiring block 1 are insert-molded is shown. However, in the present invention, not only the bus bar 3 and the terminal fitting 4 but also various articles may be insert-molded (that is, they may be parts for insert molding), and various articles are not limited to the box body 2 of the electrical connection box. May be molded. In short, in the present invention, insert molding may be sufficient.
It should be noted that the above-described embodiment merely shows a typical embodiment of the present invention, and the present invention is not limited to the embodiment. That is, it can be modified in various ways without departing from the gist of the present invention.
