Progressive die for hasps

Abstract

Provided is a progressive die for hasps. The progressive die for the hasps comprises an upper die and a lower die. Connecting holes are formed in the upper die, connecting holes are formed in the lower die, guide pillar holes are formed in the upper die, the guide pillar holes are made through wire-electrode cutting, a stripper plate is arranged between the upper die and the lower die, vent holes are formed in the stripper plate, the vent holes can exhaust air between the upper die and the lower die, the stripper plate is coated with a lubricating grease layer, and lubricating grease adopts composite lithium-base lubricating grease; by means of the vent holes, pressure air between the dies is emptied without forming static pressure, the upper die and the lower die are prone to detachment, the stripper plate is provided with connecting buckles, a lock catch between the upper die and the lower die can be firmer, displacement does not occur, the accuracy of punching is increased, a counter is arranged, counting of stamping parts can be facilitated, and the production efficiency of the die can be clearer.

Description

technical field [0001] The invention relates to a mold, in particular to a continuous mold for buckles. Background technique [0002] The frequency of use of the mold is very high. During the use of the mold, the mold is often cracked, and it is not easy to remove the mold after use, which increases the probability of the mold being scrapped. The place where the mold is used is often a relatively harsh workplace. It often needs to accept many times of stamping. In the process of stamping, the force is often uneven due to too much impact, which makes the mold easy to break, which increases the convenient capital investment of the mold and increases the cost pressure of the mold user enterprise. Long-term stamping in the process of use leads to serious bonding of the mold, which cannot be easily demolded, affects the performance of the mold, and shortens the service life of the mold. Contents of the invention [0003] The object of the present invention is to provide a cont...
