ABSTRACT:
An injection mold with a female mold portion and a male mold portion has a locking ring with beveled inner centering surfaces which, in a mold-closed position, embrace respective outer centering surfaces of the two mold portions for holding them precisely aligned for molding a thin-walled cup between a tapered core of the male portion and a cavity wall of the female portion. The core is surrounded by a stripper ring which rests on an internal shoulder of the locking ring concentric therewith and is entrainable with the latter by a stripper plate when the mold is opened. The two concentric rings may be interconnected by screws, by a snap ring, or by radially extending pins lodged in coplanar bores of the locking ring and engaging in a peripheral groove of the stripper ring, these pins having flattened faces or eccentric ends held in contact with one of the groove walls by mounting bolts which traverse the channels and secure the locking ring to the stripper plate.
