As the size of the compact increases, the powder filled in the mold tends to have a higher packing density in the lower part due to its own weight and a lower packing density in the upper part. For this reason, the upper portion of the molded body has a large amount of compressive deformation and sometimes becomes complicated such as being distorted. However, by providing the cap-shaped rubber mold according to the present invention, the shape retention of the molding die is enhanced. The effect of preventing such deformation can also be obtained.

い。In the present invention, if the height of the wall portion of the cap-shaped rubber mold is too small, the effect of the present invention due to the provision of the cap-shaped rubber mold cannot be sufficiently obtained, and if it is too large, it is difficult to mount. In addition, the pressure applied during CIP molding is changed, and the thickness of the mold is undesirably increased. The height of the wall-shaped portion is appropriately determined in consideration of the amount of deformation at the time of pressurization according to the size and shape of the molded body to be molded, but in the normal case, the thickness of the filled powder S ( 1, 2), the length (H in FIGS. 1 and 2) of the portion of the outer peripheral surface of the first outer die which is covered by the wall-shaped portion is 50 to 150.
It is preferable to set the height of the wall-shaped portion so as to be about%.
