ABSTRACT:
An injection mold has a pair of die plates upon which two mold parts are mounted and are mutually guided for relative movement. One of the mold parts comprises a pair of die jaws which are separable transversely to the direction of relative movement of the two mold parts with the jaws being guided on the respective die plate by guide assemblies disposed externally of the mold. Each guide assembly comprises a guide bar forming a groove in which a ridge of the jaws is slidable and which is affixed to a retaining bar so that the two parts abut one another in the plane of the junction of the mold part with its die plate. The retaining bar is fastened to the die plate and surfaces of the bars can be machined to compensate for wear.
