In order to inject and fill the melt into the cavity of the mold, the amount of melt injected into the injection sleeve is measured with high accuracy to correct the injection conditions of the die casting machine. A die-casting machine with a casting spoon (4), which draws molten metal from a melting furnace; an injection sleeve (7), which is injected with molten metal drawn through the casting spoon (4); an injection plunger (8) that advances or retreats in an injection sleeve; an injection cylinder (9) that advances or retreats the injection plunger (8); the injection plunger (8) is advanced through the injection cylinder (9), thereby injecting and filling the metal melt contained in the injection sleeve into the cavity of the mold of the closed mold; the molten surface height (h) of the molten metal injected into the injection sleeve from the casting spoon (4) is measured by the molten surface detection sensor (10), and the molten metal supply amount of the molten metal is measuredby calculation to correc
