Injection molding system with insertable insulating ring
Abstract
An injection molding system having a heated nozzle (10) seated in a well (30) in the mold with an insulative air space (42) therebetween. The nozzle has a resilient sealing and locating flange (48) which extends outward to bridge the air space rearward of a nose portion (26) of the nozzle. The flange (48) abuts against a cylindrical insulating ring (52) which is seated in the mold. The insulating ring (52) is made of a titanium alloy and has grooves (96) in its outer surface which form air spaces (98) to reduce heat loss from the nozzle (10) through the sealing and locating flange (48).
