Abstract

An injection molding apparatus and process for forming a plurality of first parts and a plurality of complementary second parts during a single molding cycle has a system for removing parts molded during each cycle and for assembling the parts into finished articles. The system includes a plurality of rotatable suction cups for removing the parts and for aligning them with and inserting them into a series of loading ports in a central mold member so as to mate respective ones of the first parts with respective ones of the second parts. The central mold member further has internal chute assemblies for conveying assembled articles away from the mold. A novel system for driving the rotatable suction cups uses a rotatable member mounted to various mold halves and a camming arrangement whereby relative movement of the mold halves during the mold closing and opening motions causes rotation of the suction cups.
