FORMING DIE ASSEMBLY FOR MICROCOMPONENTS

PROBLEM TO BE SOLVED: To efficiently obtain a molded article by facilitating supply of raw material powder into a pressing die in a die assembly allowing the raw material powder having plasticity to be compress-molded in the pressing die.SOLUTION: A raw material storage part 21 is formed at the upper die 20 of the pressing die 10, an upper punch hole 22 allowing the raw material storage part 21 to communicate with a cavity 11 is formed thereat, and an upper punch 50 slidably inserted into the upper punch hole 22 and opening/closing a gate 23 between the raw material storage part 21 and the upper punch hole 22 is slidably inserted into a plunger 40 with which the raw material powder P in the raw material storage part 21 is pressed and injected into the cavity 11. When the plunger 40 is pressed in while the upper punch 50 is lifted and the gate 23 is opened, the raw material powder P in the raw material storage part 21 is injected into the cavity 11 through the gate 23. When the upper punch 50 is lowered to close the gate 23 and is further lowered, the raw material powder P in the cavity 11 is compress-molded.
