PROBLEM TO BE SOLVED: To provide a casting method with a die casting machine by which the spouting accident of molten metal from a gap between an injection nozzle and a die is prevented and also, high productivity and high yield of a good product is obtained. SOLUTION: In the casting method with the die casting machine containing a process for detaching/joining the injection nozzle from/to the die in each injection of the metal by using the die casting machine, after injecting the molten metal into the die by descending an injection plunger in an injection process, the injection plunger is started to ascent on and after the pressure in a goose neck becomes the atmospheric pressure, and the die is detached from the injection nozzle in the atmospheric pressure state inside the goose neck.
