Problems solved by technology

[0002] At present, in the trimming and punching of the same part in the automobile cold stamping die, the structural design needs to be designed in the same sequence. There are many separate punching dies for wheel cover parts, which will cause the upper presser and the overall force of the die to be uneven. The knife edge is damaged too quickly, the punch is easy to undercut and the parts have burrs, etc. The parts often need to be reworked, which consumes a lot of manpower and material resources

Abstract

The invention discloses a stamping mould used for automobile parts. The stamping mould comprises an upper mould pressing core and a lower mould, wherein the lower mould further comprises a lower mouldbase, at least four balance blocks and four lifting parts; height of a polyurethane column body is greater than height of a steel sleeve; a left notch slot and a right notch slot are separately formed in the two ends of the lower mould base; at least two guide columns are arranged in each of the left notch slot and the right notch slot; a lower slide plate is arranged on each of the inner side wall, the front side wall and the rear side wall of each of the left notch slot and the right notch slot; a plurality of through holes are uniformly formed in each lower slide plate in a spaced mode, and graphite columns are embedded into the through holes; the two ends of the upper mould are separately equipped with a left convex slide block and a right convex slide block, and slide sleeves which are fitted to the guide columns are arranged in the left convex slide block and the right convex slide block; upper slide plates which are matched with the lower slide plates are arranged on the outerside wall of the left convex slide block and the outer side wall of the right convex slide block; and a plurality of through holes are uniformly formed in each upper slide plate in a spaced mode, andgraphite columns are embedded into the through holes. Integral balance and buffer of the stamping mould is improved, damages, on materials, of vibrations and strong impact force are reduced, balancedstress during contact is kept, and damage speed of the mould is also reduced.

Description

technical field [0001] The invention relates to a stamping die used for automobile parts, belonging to the technical field of stamping dies. Background technique [0002] At present, in the trimming and punching of the same part in the automobile cold stamping die, the structural design needs to be designed in the same sequence. There are many separate punching dies for wheel cover parts, which will cause the upper presser and the overall force of the die to be uneven. The knife edge is damaged too quickly, the punch is easy to undercut and the parts have burrs, etc. The parts often need to be reworked, which consumes a lot of manpower and material resources. Contents of the invention [0003] The object of the present invention is to provide a stamping die for automobile parts, which improves the overall balance and buffering of the stamping die, reduces the damage to the material caused by vibration and strong impact force, and at the same time, maintains the impact resi...
