ABSTRACT:
A device for melting, storing, and feeding a metal material is provided which can store a large amount of molten metal material corresponding to molding cycles with a compact configuration, using barrels to melt bar-shaped metal materials and a tank-and-barrel storage unit to store the molten metal material. The storage unit for the molten metal material is composed of an upper storage tank and a lower material temperature control barrel having a smaller diameter, the barrel being perpendicularly arranged under and in communication with the bottom center of the tank. The melting barrels for bar-shaped metal materials are made of barrel bodies having an inside diameter and a length appropriate to accommodate the bar-shaped metal materials. A more than one melting barrel is vertically arranged in parallel on a lid member of the storage tank, with their bottom openings facing the inside of the storage tank.
