ABSTRACT:
The present invention relates to an improved injection molding machine and process. The injection molding machine includes a first mold half with at least one mold cavity or mold core and a rotatable turret means rotatable on an axis for rotating a pair of mating mold halves into alignment with the first mold half. Each mating mold half includes at least one mold core or mold cavity matable with the first mold half for forming a mold for forming at least one molded article. The turret block is movable so that a first one of the mating mold halves can be brought into contact with the first mold half. The machine also includes an injection system for injecting molten material into the mold to form the molded article(s). After the injection cycle is completed, the turret block with the molded article(s) thereon is moved away from the first mold half and is rotated by 180 degrees to align a second one of the mating mold halves with the first mold half and to bring the molded article(s) to an ejection position. Thereafter, the molded article(s) are allowed to be dropped via gravity onto a molded article receiving device.
