ABSTRACT:
A material supplying apparatus for a powder molding machine including a press table, a charger frame movable to reciprocate on the press table, a device for reciprocating the charger frame, a material inputting device provided on the charger frame into which a powder material is supplied, a scaling device for previously scaling the powder material to a predetermined weight, the device for scaling including a load cell, and rotary blades attached to a vertical shaft positioned in order to stir the material supplied to the material inputting device. The reciprocating device for the charger frame coupled to the material inputting device comprises a first cylinder which is reciprocated on the press table. A shutter plate is arranged between the material inputting device and the table in slide contact with both the material inputting device and the table through dust seals for opening and closing openings of the material inputting device. A second cylinder is interposed between the shutter plate and the charger frame.
