<P>PROBLEM TO BE SOLVED: To prevent air from infiltrating into a cylinder when a die casting component is cast by a hot chamber die casting machine. Ž<P>SOLUTION: The hot chamber die casting machine includes a molten metal tank 10 in which molten metal of a fused metal material is put in, a cylinder 31 arranged so that molten metal can be supplied from the molten metal tank through a molten metal feed path 12, a plunger 40 arranged freely slidably in the cylinder, and a molten metal feed path (goose neck) 32 that guides molten metal inside the cylinder to a nozzle by sliding of the plunger. With the nozzle 50 connected to casting dies 61, 62, the molten metal flowed out from the nozzle by the sliding of the plunger 40 is filled in the dies for casting. In the present invention, the volume of the molten metal feed path 32 is made larger than the volume change quantity inside the cylinder 31 when the plunger 40 is slid for the purpose of filling the molten metal in the casting dies.
