ABSTRACT:
An injection mold with a female mold portion and a male mold portion has a locking ring consisting of two releasably interconnected annular members with respective tapering 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 is received with a certain amount of axial play between internal shoulders of the locking-ring members for joint entrainment by a stripper plate when the mold is opened.
