Abstract:
1. An injection molding machine for low-melting point metallic material comprising: an injection mechanism comprising a melting cylinder, an injection means and a driving device; said melting cylinder having a supply port for a metal material disposed on an upper side of an intermediate portion, a metering chamber formed within a tip portion, the metering chamber having a selected length in communication with a nozzle member; said injection means comprising an injection rod disposed within the melting cylinder so as to advance and retreat freely, and an injection plunger attached to a tip of the injection rod, the injection plunger being inserted into the metering chamber freely slidable; and said driving device disposed on a rear end of the melting cylinder for driving said injection means so as to advance or retreat; a pedestal supporting said injection mechanism obliquely with the nozzle member directed downwardly to a mold clamping mechanism, the pedestal provided on an upper surface of a base so as to advance and retreat freely; wherein: a nozzle touch block is provided on a tip end portion of the pedestal and touched by said nozzle member obliquely; a frame is provided on a rear portion of the pedestal and supports a rear portion of said injection mechanism and the driving device obliquely; a nozzle touch device is provided for nozzle touching an injection nozzle attached to the front of the nozzle touch block to a mold in the mold clamping mechanism by moving the pedestal with said injection mechanism toward the mold clamping mechanism.
