PURPOSE:To enable quick forming of powder molded articles of different materials by connecting correspondingly plural feeders placed freely slidably on a supporting table which is flush with the top of the die plate in a die set to the same number of hoppers. CONSTITUTION:A driving mechanism 4 disposed on a press side is started and a feeder 21a is advanced from above a rotary table (supporting table) 20 onto the die 12 of a die plate 13. Powder 3 for molding is beforehand fed from the corresponding hopper, via a hose 26, into a feeder 21a. The feeder 21a arriving at the part above the die 12 supplies automatically the internal powder 3 smoothly and surely into the die 12 and is again moved backward onto the above table 20 by the mechanism 4 and is stopped in a prescribed position. The powder 3 is molded by being compressed by a top punch 16 and bottom punch 11 which are lowered by the operation of an upper ram 19'' and is knocked out onto the plate 13 when the plate 13 descends. |
