A molten metal feeding device is provided to improve safety and productivity by rapidly and accurately feeding molten metal. A molten metal feeding device includes a molten metal reservoir(10), a stainless pipe, a transfer pipe(20), a pressing unit(40), an air pipe(50), and a control panel. The molten metal reservoir includes a rectangular body(11) and a cover(12). The body is cased by a ceramic insulating board and a silica fire-resisting board, and receives molten metal. The cover is separable and covers the body. The stainless pipe is adhered on a side of the molten metal reservoir. The transfer pipe is a ceramic pipe embedded dual pipe and installed inside the stainless pipe for sucking and discharging the molten metal. The pressing unit feeds compressed air. The air pipe is connected to the pressing unit above the molten metal reservoir, and has a three-way solenoid valve(45) dividing the air pipe into a pressing line(A) and a vacuum line(B). The control panel controls the air pressure pumped from the pressing unit by opening and closing a valve which is electrically connected thereto.
