Patent ID: 7926546

Claim:
A device for melting, storing, and feeding a metal material from a bar-shaped metal material intended for an injection apparatus for molding a metal product, the device being arranged on an injection cylinder having an injection plunger inside, and feeding a molten metal material into the injection cylinder one shot at a time, the device comprising: a storage unit for the molten metal material, including: an upper molten metal cylindrical storage tank; a lower material temperature control barrel having a diameter smaller than an inside diameter of the cylindrical storage tank; the material temperature control barrel being perpendicularly arranged under a bottom of the storage tank so as to communicate through an opening formed in a center of the bottom of the storage tank; a lower inner wall of the material temperature control barrel being gradually reduced in inside diameter narrowing toward an outlet in a bottom center thereof; the outlet communicating with a feed opening formed in a top of the injection cylinder; a lid member fixed to an open top rim of the storage tank; and heating means arranged around peripheries of the storage tank and the material temperature control barrel, and a plurality of melting barrels having respective barrel bodies having an inside diameter and a length appropriate to accommodate the bar-shaped metal material; heating means being arranged around peripheries of the barrel bodies, the barrel bodies being vertically arranged in parallel on the lid member with bottom ends thereof inserted into a corresponding plurality of holes formed in both side areas within a surface of the lid member so that bottom openings thereof open into the storage tank.
