ABSTRACT:
A mold construction for allowing molding of parts having elements with a helical configuration. The helically configured portion is formed by a portion of the mold that is freely rotatable relative to the rest of the mold about the axis of the helically configured portion. The extraction of the molded component from the mold along a path coextensive with the axis of the helically configured portion produces driven rotation of the rotatable mold portion thereby releasing the molded component.
