Injection molding apparatus for accommodating various sizes of molding die inserts

Abstract

An apparatus for accommodating various sizes of molding die inserts in an injection molding machine using a pair of injection die support frames to hold either injection molding die inserts fitting directly into corresponding recesses in confronting faces of the die support frames or second injection molding die inserts combined with respective injection die insert adaptors fitting into the recesses in the die support frames. An adjustable stop for the confronting faces of the die supports is provided in confronting face of one of the die support frames to maintain a uniform parting line between the die support frames and the die inserts by providing a selectively elevatable contact surface above the parting line facing surface of the one die support frame. The selectively elevatable contact surface is located on the head of a threaded screw held in the one die support frame and is adjusted to contact the confronting face of the other die support frame when the confronting faces of the die inserts are in contact.
