Claim Text:
1. A die casting apparatus comprising: a mold having a cavity; a plunger sleeve having a molten metal feed port, the plunger sleeve being communicated with the cavity; a plunger tip provided at a distal end portion of a support shaft, the plunger tip configured to be slidable in the plunger sleeve in an axial direction of the plunger sleeve when the support shaft is inserted into the plunger sleeve; a molten metal holding furnace in which molten metal is stored; and a pump that feeds the molten metal from the molten metal holding furnace into the plunger sleeve, wherein casting is performed through an injecting operation in which the molten metal fed into the plunger sleeve is extruded by the plunger tip to be injected into the cavity, the pump includes a pump body and a connecting pipe, the pump body being disposed at an end portion of the molten metal holding furnace, the end portion being located on the plunger sleeve side, the connecting pipe being connected to the pump body and the plunger sleeve to provide communication between the pump body and the molten metal feed port, and the connecting pipe being separable from the pump body, and the die casting apparatus further comprises a moving mechanism configured to allow the pump body to move between an inclined state where the pump body is inclined with respect to a horizontal plane in the molten metal holding furnace and an upright state where the pump body is perpendicular to the horizontal plane in the molten metal holding furnace, with the pump body and the connecting pipe separated from each other.
