PROBLEM TO BE SOLVED: To provide a die apparatus for injection molding which facilitates the supply of a raw material for efficiently producing a molded part having a thin part. SOLUTION: A die for metal powder injection molding is disclosed in which a plastic raw material M composed of metal powder and a binder is injection-filled into a cavity provided at the inside of a die composed of a fixed die 10 and a movable die 20 from a gate 51 provided at least either the fixed die or movable die. At least either the fixed die or movable die is split into a plurality of dies, the plastic raw material composed of the metal powder and the binder is injected-filled into the cavity, and thereafter, the dies split into two or more are driven, consequently the volume of the cavity is made fixed to deform the cavity, and further, the plastic raw material filled into the cavity is deformed at a fixed volumes to mold a molded body P.
