ABSTRACT:
A method of loading a moldset having a core plate and a cavity plate into an injection molding machine. The method comprises the steps of latching a cavity plate to a core plate using a removable latch, guiding the core plate into an open mold along a face in the mold while maintaining separation between the face and the core plate and maintaining the cavity plate spaced from hot runner nozzles in a hot runner in the mold, closing the mold to engage the cavity plate with the hot runner nozzles, securing the cavity plate to the hot runner, removing the latch between the cavity plate and the core plate, and opening the mold. The face may be a face of a movable platen or a back surface of a hot runner.
