Abstract
An injection device of a light metal injection molding machine includes: a first inert gas storage part creating an inert gas atmosphere around a plunger insertion portion of an injection cylinder; a second inert gas storage part housing surplus molten metal in a melting cylinder and creating an inert gas atmosphere above the molten metal; and a first pressure adjustment part adjusting a pressure in the first inert gas storage part to a pressure equal to or less than a pressure obtained by adding a pressure, which is determined based on a value obtained by multiplying a specific gravity of the molten metal by a height difference between a highest position and a lowest position of the molten metal in a part that includes the inside of the injection cylinder and communicates with the inside of the injection cylinder, and a pressure in the second inert gas storage part.
