GREEN COMPACT MOLDING DIE DEVICE FOR PLATE-LIKE COMPONENT

PROBLEM TO BE SOLVED: To provide a green compact molding die device for a plate-like component capable of preventing a crack having an inner corner part of a die as a start point from being generated, even when carrying out compression molding at high pressure, and allowing exact molding even when using raw material powder of high hardness.SOLUTION: A core member 20 for forming two cavities 50 by partitioning an inside of a die hole into two is inserted in the center of the inside of the die hole of a die 10, and raw material powder supplied into each cavity 50 is compressed, by upper and lower punches 40 inserted freely slidably into each cavity 50, to form a green compact of a plate-like component. A stress at compression molding applied to an inner corner part is leaked to a junction boundary face between an inner wall face and an outer wall face 21, by forming the right-angled inner corner part of the cavity 50 of the inside face of the mold hole and the outer wall face 21 of the core member 20, and a crack having the inner corner part of the die as a start point is thereby prevented from being generated, to allow molding at high pressure.
