摘要

A powder molding machine capable of uniforming a density of molding powder packed into an extrusion space of a die and improving the strength of a molded article. The machine is provided with a die (2), punches (13, 14) and a feeder (7), and further with feeder driving means for reciprocatingly moving a feeder shoe (1) between an advancing position at which molding powder is fed and a retreating position at which compression operations of the punches are not hindered. Furthermore, this feeder driving means is provided with a driving mechanism for passing the feeder shoe (1) on the die (2) while being swung to the right and left when the feeder shoe (1) is moved back.
