To efficiently discharge molten metal remaining after supplying into a mold.
An apparatus 11 for feeding the molten metal, is provided with; a molten metal feeding vessel 13 for feeding the molten metal fed from a molten metal supplying vessel 12, into the mold 25, with a molten metal feeding cylinder 23; a connecting vessel 15 for feeding the remained molten metal; a discharge vessel 16 for discharging the molten metal; a communicating tube 32 arranged so that the one end is proximately opposite to the bottom surface of the molten metal feeding vessel 13 and the other end is proximately opposite to the bottom surface of the connecting vessel 15; a communicating tube 33 arranged so that the one end is proximately opposite to the bottom surface of the connecting vessel 15 and the other end is proximately opposite to the bottom surface of the discharge vessel 16; a supply/discharge device 37 for supplying/dischaging gas into the upper part of a cover part in the molten metal feeding vessel 13; a supply/discharge device 41 for supplying/discharging gas into the communicating tube 32; and a supply/discharge device 45 for supplying/discharging gas into the communicating tube 33. The molten metal remaining in the molten metal feeding vessel 13 is fed into the discharge vessel 16 having lower molten metal surface by utilizing a siphon phenomenon while evacuating the communicating tubes 32, 33 with the supply/discharge devices 41, 45.
