Abstract:
A method of injection molding a layered plastic component comprising:providing a sealing structure around the periphery of a mold cavity formed between first and second mold halves to contain plastic material in the cavity during injection; closing the first and second mold halves to a first gap therebetween; injecting a first plastic material into the cavity; closing the first and second mold halves together to a full closure position; holding the first and second mold halves together for a period of time sufficient to partially solidify the first plastic material; opening the first and second mold halves to a second gap therebetween; moving by lateral actuation at least one stop member into position between the first and second mold halves by providing the stop member laterally moveable with respect to one of the first and second mold halves, and moving the step member between a first position in alignment with a corresponding pocket on the other mold half and a second position out of alignment with the pocket and abutting the other mold half to form a gap between the first and second mold halves; injecting a second plastic material into the mold cavity; and closing the first and second halves together against said stop member, and maintaining the mold halves against the stop member for solidification of the second plastic material to form the layered plastic component.
