Claims

[Claims for Utility Model Registration] Powder in which the outer shape of a molded product is formed using a die, and the metal powder filled into a metal powder filling cavity formed by the die and lower punch is compression-molded using an upper punch and a lower punch. 1. The upper punch has a concave part for forming the convex part of the molded product, and the lower punch has an outer punch for forming the flat part of the molded product and an inner punch for forming the convex part of the molded product. The outer punch consists of a punch and has a notch with a horizontal top surface at the bottom of the molding. When filling the metal powder, the outer punch is pushed up until it comes into contact with a stopper attached to the punch plate, and during compression molding The lower punch is fixed to the lower punch holder which abuts the punch plate located below, while
A collar-shaped portion with a horizontal upper surface is provided on the lower side wall of the inner punch, and an elastic body is disposed between the upper surface of the notch for the outer punch and the upper surface of the collar-shaped portion of the inner punch. 1. A powder molding mold characterized in that the inner punch is always urged downward to form a metal powder filling cavity when filling the metal powder with a die, an outer punch, and an inner punch.
