動作の一行程を完了する（第４図(d)）。Conventionally, molding of a powder compact by this type of powder compacting apparatus has been performed using a plurality of upper punches and lower punches and a die having the same number of holes. The operating state of the molding section of this powder molding apparatus will be described in the order of steps with reference to the sectional views of FIGS. 4 (a) to 4 (d). First, the powder supply box 4 on the die 2 is swung or vibrated so that the powder A in the powder supply box 4 is inserted into the plurality of holes 2a of the die 2 and the same number of lower punches 3 which are fitted into the holes 2a.
The hole formed by the upper end surface 3a of the
Figure (a). Next, after the powder supply box 4 is slid and retracted, the same number of upper punches 1 as the holes 2a of the die 2 are lowered and the die 2 is moved.
The powder A is inserted into the holes 2a from the upper side to compress the powder A from the upper surface (FIG. 4 (b). Next, the lower punch 3 is lifted to compress the powder A from the lower surface to a desired external dimension. A molded body B is formed (FIG. 4 (c)). Next, the upper punch 1 is lifted to pull out the tip of the upper punch 1 from the hole 2a of the die 2 and then with a slightly delayed operation. The lower punch 3 in the hole 2a of the die 2 is lifted to eject the compact B from the die 2. Next, the powder supply box 4 is moved forward onto the die 2 and molded at the outer peripheral portion of the tip of the powder supply box 4. After discharging the body B from the die, the lower punch 3 is lowered to complete one step of the powder molding operation (FIG. 4 (d)).
