DIE CASTING APPARATUS AND DIE CASTING METHOD

WIPO Patent Application WO/2006/001325

A1

A die casting apparatus capable of easily casting a molding without causing shrinkage cavities and inclusion of gases by rapidly filling a molten metal in a metal mold cavity and effectively pressurizing the molten metal in the closed cavity, excellent in working efficiency, easily maintainable, and manufacturable at low cost, and a die casting method using the apparatus. The apparatus comprises an apparatus body having a fixed mold (1) and a movable mold (2) capable of forming the metal mold cavity, a casting sleeve (5) installed on the fixed mold (1) and communicating with the metal mold cavity (C), and a plunger (6) sliding in the casting sleeve (5) to fill the molten metal fed to the casting sleeve (5) into the metal mold cavity (C) and a casting means feeding and filling, from the underside, the molten metal into the casting sleeve (5) through a molten metal feedout opening (51) formed in the casting sleeve (5). The casting means further comprises a gas-pressurized molten metal pouring cradle (7) attachable to and detachable from the apparatus body.
