A metal forming apparatus (1000) includes a smelting device (5), a molding device (10), an injection device (8) and a vacuumizing device (3). The smelting device (5) defines a smelting chamber (501), and includes a rotatable crucible (502) and a heating unit (003) both disposed within the smelting chamber (501). The molding device (10) defines a molding chamber sealedly communicated with the smelting chamber (501). The injection device (8) includes a charging barrel assembly (81) sealedly disposed at a joint between the molding device (10) and the smelting device (5) and an injection unit sealedly connected with the smelting device (5). The vacuumizing device (3) is sealedly connected with the smelting device (5) and the molding device (10) respectively so as to vacuumize the smelting chamber (501) and the molding chamber. The space volume which needs to be vacuumized is greatly reduced, thereby being favorable for guaranteeing the leakproofness and the pressure maintaining performance of a vacuum space. |
