PURPOSE:To obtain a powder molding which is uniform in height size accuracy and compression density by supplying the raw material powder housed in a feeder by circularly moving the feeder in the upper part of a cavity into the cavity. CONSTITUTION:The feeder 26 can be circularly moved around the arbitrary position on the cavity 56 and, therefore, the unequal packing is eliminated so as to obtain the good product while the packing state or the state of the powder molding is checked. The side face of the feeder 26 is formed to an arc shape in such a manner that the feeder 26 is oscillated around a spherical bearing 38 part to accelerate the falling of the raw material powder 28 at the time when the feeder 26 moves circularly. The raw material powder is, therefore, packed uniformly in the respective parts of the cavity 56 and as a result, the powder molding which is press-molded to the good height size accuracy and the uniform compression density is obtd. |
