PROBLEM TO BE SOLVED: To perform multi cavity mold while adoviding the increase of the fastening force and the enlargement of forming apparatus. SOLUTION: In a die casting machine, an intermediate die 36 is arranged between a fixed die 40 and a movable die 42. A transmitting device transmits the shifting of the movable die 42 with a die fastening device to the intermediate die 36 while permitting the approach and the separation in a fixed distance. The movable die 42 and the intermediate die 36 approach the fixed die 40 to form two cavities 60, 62 in series in the dies 40, 36, 42 kept in close contact with respective parting surface 50, 52, 54, 56. The lower end parts of the cavities 60, 62 are set to communicate with sleeves 114, 116 having a sprue through runners 110. The sleeves 114, 116, plunger tips 124 moving slidably in the sleeves 114, 116 and injecting devices 130, 132 containing cylinders for driving the plungers, are arranged so as not to be relatively moved to a fixed plate 16. Molten metal is injected into the cavities 60, 62 with the injecting devices 130, 132, and after solidifying the molten metal, the dies 36, 40, 42 are opened and the formed products are pushed out with ejecting devices 136.
