Title: DIE CASTING MACHINE
Abstract:
[Problem] To measure with high accuracy the amount of a melt poured into an injection sleeve in order to inject and fill a mold cavity with the melt. [Solution] A die cast machine comprises a ladle 4 that scoops up molten metal from a melting furnace, an injection sleeve 7 into which the molten metal scooped up by the ladle 4 is poured, an injection plunger 8 that advances and retreats inside the injection sleeve, and an injection cylinder 9 that causes the injection plunger 8 to advance and retreat, the molten metal inside the injection sleeve being injected and charged into the cavity of a closed mold by the injection cylinder 9 advancing the injection plunger 8, wherein said die cast machine comprises a magnetostriction type melt surface sensor 10 that measures the melt surface height h of the molten metal poured into the injection sleeve from the ladle 4.
