APPARATUS FOR THE FABRICATION OF INJECTION-MOLDED OR DIE-CAST ARTICLES

摘要

An apparatus for the fabrication of injection-molded or die-cast articles equipped with a thread, e.g. such articles as screw-closing caps. The apparatus comprises an injection-molding tool unit including forming sets for the articles to be injection-molded and a driving unit which includes at least one drive pinion. A threaded core is disposed on the side of the injection-molding tool unit. The drive pinion serves for the removal of the threaded core. The driving unit is designed as an independent drive set, separate from the injection-molding tool unit and useable independently. The drive pinion is releasably connectable together with the threaded core provided separately on the side of the injection-molding tool from the drive set by coupling means.
