Mold and method for micro part machining

Abstract

The invention discloses a mold and method for micro part machining. The die comprises an upper punch and a lower forming die which are oppositely arranged, a workpiece male die is arranged on the endface, facing the lower forming die, of the upper punch, a workpiece female die is arranged on the end face, facing the upper punch, of the lower forming die, and a flange lower die is arranged in thelower forming die in a sleeved mode; the top end face of the flange lower die abuts against the bottom end of the female die to jointly form a groove structure with an opening facing the male die, a matching hole is formed in the top of the supporting cover, the upper punch moves in the axial direction, penetrates through the matching hole and then is matched with the lower forming die to be usedfor enabling the male die and the female die to be matched to conduct punch forming on materials, punch forming is conducted through cooperation of plates of different thicknesses and a special punchdie, and the forming precision of micro parts is directly controlled by the precision of the die. Compared with traditional injection molding, powder forming and other modes, higher machining precision and machining efficiency can be provided, and therefore the existing precision requirement for micro parts is met.
