A die casting device (30) includes a die (1 ) including a cavity (4); an injection. sleeve (2) including a feeding orifice (6) and communicating with the cavity; an injection tip (3) provided at the distal end of a support shaft, and is configured to be slidable in an axial direction within the injection sleeve by inserting the support shaft into the injection sleeve; a decompression device (21, 22) communicating with the cavity; a molten-metal holding furnace (50) including a space to store molten metal; a pump (40) pumping up the molten metal from the molten-metal holding furnace; and a feeding pipe (41, 42) including a first end connected to the pump and a second end communicating with the feeding orifice. The feeding pipe (41, 42) is joined to the injection sleeve through a relay pipe (61) including a vibration absorption portion, the molten metal is fed into the injection sleeve (2) from the molten-metal holding furnace through the feeding pipe by the pump, and is pushed out of the injection sleeve (2) by the injection tip, and the molten metal is injected into the cavity (4) decompressed by the decompression device (21, 22), thereby casting is conducted. |
