PROBLEM TO BE SOLVED: To supply molten metal so as to reduce impurities and improve fluidity in manufacturing multiple articles. SOLUTION: Four cavities 5 are arranged on a concentric circle C relative to the center O of flow dividers 15 and molten metal sleeves 13, and are connected to sleeve stamp parts with four mold side runners 6 each radially formed and independent from adjacent runners and with stamp side runners 16. A half-arc shaped storage part 21 is formed on the lower half sides of the flow dividers 15 and the molten metal sleeves 13, and the storage part 21 is connected to the sleeve stamp parts. A semi-solidified layer formed by an injection of molten metal into the sleeves is filled in the storage part 21, and the molten metal separated from the semi-solidified layer is directly supplied from the stamp runners 16 through the mold side runners 6 sides to be filled into the cavities 5 simultaneously and evenly.
