Die casting machine and die casting method

A die casting method in which molten metal is injected from a plunger sleeve section provided in a metallic mold and the injected molten metal is filled in a cavity product section via a runner so as to produce a die casting product, comprising the steps of:

• decompressing the product cavity section and the plunger sleeve section before molten metal is injected from the plunger sleeve section when a powder mold releasing agent is supplied to the product cavity section and the plunger sleeve section;
• advancing a powder discharging pin, which is arranged in the runner in a retractable state and has a powder introducing passage connected with a powder supply source, into the runner;
• opening a first opening section provided in the powder introducing passage of the powder discharging pin toward the product cavity section and also opening a second opening section provided in the powder introducing passage toward the plunger sleeve section;
• and
• discharging the powder mold releasing agent from the first and the second opening section.
