ABSTRACT:
A cut-off nozzle system is mounted on the melt conduction duct of the center, sectioned mold clamping plate of an injection molding machine, in such a way that in addition to rapid accessibility of the individual parts of the nozzle system, the center, section mold clamping plate can be easily and quickly separated from the associated screw unit as required for the removal of the molded parts from the molds. The nozzle system has a spacing ring with a torpedo as well as a right-angled adapter and a cut-off nozzle, which parts are exchangeably joined with each other to form one rigid unit. With a high-speed clamping device, this unit is fastened on the movable center, sectioned mold clamping plate. For the upward removal of the molded parts, the screw unit is displaced sideways while the cut-off nozzle system remains mounted on the center mold clamping plate.
