INTEGRATED MULTIPLE EDGE GATE

摘要

The present invention is an improved injection molding nozzle. The improved nozzle includes a nozzle body having a central melt channel and a terminal end. A distributor block is formed on the terminal end of the nozzle body, the distributor block having a nozzle melt channel and a series of distributor melt channels radiating from the nozzle melt channel. The nozzle melt channel is coupled to the central melt channel and each distributor melt channel terminates in a melt well. The improved nozzle further includes a nozzle ring which is forme d on the end of the terminal end of the nozzle. The nozzle ring surrounds the distributor block and has a plurality of gate feeders, each of said gate feeders being in communication with a melt well. The distributor melt channels radiate symmetrically from the nozzle melt channel to feed the melt wells. The distributor block is made of a highly thermally conductive alloy such as BeC u and a heating mantle is provided on the nozzle body for keeping the nozzle at a suitable melt temperature.
