PURPOSE:To prevent clogging of a molten metal injecting nozzle, and also to prevent a molten metal from leaking, by moving a metallic mold unit directly by a rod of an oil pressure cylinder. CONSTITUTION:A moving metallic mold 25 and a fixed metallic mold 24 are clamped with a rod 30 by operating the first oil pressure cylinder 31. Subsequently, the second oil pressure cylinder 32 is operated, a metallic mold unit 17 is moved, and a nozzle 21 of a molten metal injecting device 16 is made to communicate with a sprue runner 22 of the fixed metallic mold 24. A molten metal is injected into a cavity 26, and when casting is finished, a rod of the second oil pressure cylinder 32 is shrunk, and the metallic mold unit is moved backward. Subsequently, the rod 30 of the first oil pressure cylinder 31 is shrunk, the moving metallic mold 25 is detached from the fixed metallic mold 24, the rod 30 is projected, a product of the moving metallic mold 25 is removed by an extruding pin 27, and after that, the moving metallic mold 25 is moved and is clamped together with the fixed metallic mold 24. Subsequently, the tip of the extruding pin 27 is moved backward from the inside of the cavity 26 and is drawn out by operating the first oil pressure cylinder 31. |
