MOLDING DIE FOR POWDER MOLDING

摘要

PROBLEM TO BE SOLVED: To provide a molding die for powder molding to produce a powder molded product in which the wall thickness of a given section is made to be thick while the wall thickness of other section is almost uniform. SOLUTION: A molding die 1 is constituted of a female mold 3 and a holding member 11. A molding section 4 for manufacturing a molded product by making thermoplastic resin powder in the molten state adhering to the inner wall is formed on the female mold 3, and a power introduction opening 5 for introducing the thermoplastic resin power is formed in one side. A holding member 11 for holding the female mold 3 is provided on the peripheral edge of the powder introduction opening 5 of the female mold 3. The female mold 3 is formed in the almost uniform thickness (t), and the thickness T of the given sections is thicker than that of the other sections. When the molding die 1 is heated up to the melting temperature of the thermoplastic resin powder and the thermoplastic resin powder is introduced into the female mold 3, the melting temperature of the given sections can be kept thanks to the wall thickness thicker than that of the other sections, and the thickness of molten resin layers adhering to the inner walls of the given sections can be formed thicker than that of the other sections.
