の加圧成形装置。[Scope of Claim for Utility Model Registration] In an apparatus for pressure forming a disk-shaped powder molded product having a thin disk portion between a boss portion and a rim portion, a lower punch inserted into a die and a lower punch and an upper punch that faces the rim and is driven up and down by a press ram, and the lower punch moves downward together with a first lower punch that forms the rim part and a die during pressure forming, and that moves downwardly to form the disc part. and a third lower punch that forms the boss portion.The upper punch is fixedly supported by an upper holder that is driven up and down by a press ram, and is opposed to the first lower punch. A second upper punch, which is supported by the upper holder so as to be able to move up and down, and which is opposed to the second lower punch and is provided with an auxiliary force in the pressing direction by a cushion cylinder during pressure forming; movably elastically supported and the third
A pressure forming apparatus for a powder molded product for sintering, comprising a lower punch and a third upper punch opposed to the lower punch.
