PROBLEM TO BE SOLVED: To easily keep up with the variation of molten metal supplying quantity while securing the molten metal supplying quantity into a horizontal injection sleeve in a high accuracy. SOLUTION: Molten metal 29 held in a metal melting furnace 31 is fed into a fixed quantity holding chamber 46 in a cylinder 45 from a molten metal supplying tube 33 through a discharging passage 59 in a switch valve 53 by driving a solenoid pump 35. The molten metal quantity necessary for a single injection work is weighed by detecting the raised position of a float 47 with a stroke sensor 51. The switch valve 53 can be shifted in the orthogonal direction to the paper surface in the picture, and a regulated quantity of the molten metal in the fixed quantity holding chamber 46 is supplied into the horizontal injection sleeve 25 by gravity by communicating the fixed quantity holding chamber 46 with the horizontal injection sleeve 25 with this shifting.
