CN205386591U - Flip -chip of T type stamping workpiece compound mould of blanking that punches a hole - Google Patents

Abstract

The utility model discloses a compound mold for flip-chip punching and blanking of T-shaped stamping parts. The stamping compound mold includes an upper mold base and a lower mold base. The upper mold base is provided with a punching punch and a concave mold, and the convex and concave molds are fixed on the lower mold. On the seat, during the downward process of the pressure bed, the punching and blanking of the T-shaped stamping part can be completed at one time through the cooperation of the punching punch and the die and the punch and die. The mold leaks, and the workpiece is easier to pull out when pushed down from the upper mold. The operation is convenient and safe, and the requirements for materials are not strict. Leftover materials can be used, which reduces the production cost and solves the problem caused by one workpiece being stamped and formed on two sets of molds. The problem of high cost and low efficiency.
