PURPOSE:To remarkably save heat energy and also to improve the working atmosphere by charging metal pieces in order by circulating plural crucibles arranged annularly and pouring molten metal in order into the injection apparatus by melting in a heating furnace. CONSTITUTION:The crucible 12 is respectively held to plural rotating arms 10 arranged radially to the rotary axis 9, and the crucible 12 is annularly circulated by rotating the rotary axis 9 by a motor 8. The metal pieces are charged in order in the crucibles 12 and an arc-like passage 15 of heating furnace 12 is passed to melt the metal pieces. Next, when the crucible 12 come to just above the pouring hold 3 of injection apparatus 1, a hook part 20 of hanging-up lever 23 is engaged with a projection 19 of the crucible 12 and the hanging lever 23 is drawn up by driving a cylinder 22. In this way, the crucible 12 is turned and tilted as becoming supporting point 13 to the center, and the molten metal in the crucible 12 is flowed into the plunger sleeve 2 through the pouring hole 3. In this way, the molten metal for die casting is automatically and continuously supplied into the injection apparatus 1.
