Abstract:
PROBLEM TO BE SOLVED: To provide a powder feeding device which can stably feed a fixed amount of powder to a mold cavity.SOLUTION: A powder feeding device 1 to feed powder P to a mold cavity 15 comprises a powder box 31, a storage chamber shutter 32 and a control part 50. The powder box 31 includes a storage space 310 storing the powder P, and can move between a retreat position where an upper surface 1113 of a die 11 faces the storage space 310 and a powder feeding position where the storage space 310 communicates with the mold cavity 15. The storage chamber shutter 32 can perform switching between a closed state in which the storage space 310 is partitioned into a first storage chamber 313 and a second storage chamber 315 and an open state where the first storage chamber 313 and the second storage chamber 315 communicate with each other. The first storage chamber 313 is arranged on an upper side in a vertical direction, and the second storage chamber 315 is arranged on a lower side in the vertical direction and has a volume larger than the volume of the mold cavity 15. The storage chamber shutter 32 can divide and feed the powder P of the storage space 310 into the first storage chamber 313 and the second storage chamber 315.SELECTED DRAWING: Figure 1
