Title:
DIE AND METHOD FOR POWDER COMPRESSION MOLDING
Document Type and Number:
Japanese Patent JPH06179098
Kind Code:
A
Abstract:

PURPOSE: To improve air-vent property in powders by constituting the powder contact part of a die of a porous body having pores communicating with the inside and the outside of the mold.

CONSTITUTION: A powder compression molding die 10 is constituted of a mortar 11 and upper and lower rods 12, 13. After filling powders in the mortar 11 for which the lower rod 13 is inserted and arranged in a prescribed position, the upper rod 12 is inserted into the mortar 11 for the compression molding of the powders, and a molded article is pushed up by the lower rod 13 outside the mortar 11 to be discharged. Here, the mold 10 is constituted of a metallic porous body 15 for the whole body including the powder contact part 11A of the mortar 11. At the unfilled time of powders into the die 10, a pressurized fluid is applied through a pressure chamber 17 to the outside surface of the die that is constituted of the porous body 15, and the powders filling the pores of the porous body 15 are blown away inside the die. Consequently, the positional relation to constitute the die, e.g. between the mortar and the rods is set freely.
