Abstract
The invention generally discloses an apparatus and method for removing threaded, molded articles from an injection mold. A cam system and linear drive/following gear mechanism engages a finely resolved retraction of a threaded mold core, under substantially full mold clamp pressure, prior to rotational disengagement of the core from the molded article. The invention also describes a system for the reduction of galling that may otherwise occur when mold components experience relative rotation with respect to each other. Moreover, the invention describes an apparatus and method for substantially reducing periodic maintenance checks and interruptions in production.
