Abstract:
A slide retainer for a mold having mating segments that are movable relative to each other and together form a mold cavity, and a linearly movable slide mounted in one of the mold segments that traverses a predetermined stroke to move a core element relative to the mold cavity, the slide retainer comprising:(a) a wear plate including a latch detent and configured to be received in a corresponding recess in the slide wherein the length of the wear plate in the direction of travel of the slide is no less than the length of stroke of the slide, the wear plate being made of a material having a greater hardness number than the material from which the slide is made; and (b) a spring-loaded plunger mounted adjacent the wear plate, such that the plunger remains in contact with the wear plate throughout the stroke of the slide and engages the latch detent when the slide moves to the end of its stroke that corresponds to an open mold condition.
