<p>REAR OPENING MOLD A mold, typically an injection mold, comprises a cavity member and a core member relatively movable between open and closed positions to define a first parting line and a molding chamber between the core and cavity members in the closed position. A sprue aperture is provided, communicating with the molding chamber to provide molding compound to the chamber. In accordance with this invention the cavity member defines forward and rearward portions movable between open and closed positions and proportioned whereby objects molded in the molding chamber can be removed from between the forward and rear portions when the cavity member is in its open position.</p> |
