Abstract
PURPOSE:To easily compact cavity having optional hole diameter and depth size in the producing sintered body by constituting under assembling a cylindrical cavity block of the compacting die into a die holder combined with upper and lower punches as inserting type. CONSTITUTION:The cylindrical cavity block of the powder alloy using super hard powder as raw material is assembled into the die holder 9b as inserting type, so as to combine the upper punch 10 with the lower punch 11 to constitute the die for producing small-sized parts. The cylindrical cavity block 9a packs the powdery raw material 16 for super hard material into a pressing die providing a core 15, which selects the dimensional shape having a little larger than the finishing dimensional shape in the cavity 8 by shrinkage size caused by sintering, and after compacting by pressurizing, the core 15 is taken out to produce the compact by vacuum-sintering. By this method, the cavity having the optional hole diameter and depth size is easily compacted and the durability of the die is improved.
