Automobile roof part drawing die

Abstract

The invention relates to an automobile roof drawing die. The drawing die comprises a lower die assembly, a pressure plate and an upper die assembly. The pressure plate is arranged between the lower die assembly and the upper die assembly. The upper die assembly comprises an upper die base, an upper die core and a guide plate guide bush, wherein the upper die core and the guide plate guide bush are arranged on the upper die base; the upper die core is arranged below the upper die base, and is provided with a roof drawing female die; the lower die assembly comprises a lower die base, a lower die core, a guide plate guide post and an ejector pin, wherein the lower die core, the guide plate guide post and the ejector pin are arranged on the lower die base; the lower die core is arranged below the lower die base, the lower die core is provided with a roof drawing male die, and the guide plate guide post extends into the guide plate guide bush; and the pressure plate comprises a pressure plate body, a pressure plate balanced cushion block and an ejector pin cushion block, the ejector pin cushion block is arranged between the pressure plate body and the ejector pin, and the pressure plate balanced cushion block is arranged between the pressure plate body and the upper die base. Compared with the prior art, the die disclosed by the invention has the advantage that in the drawing process, the rate of finished products of workpieces is improved because of uniform moving of parts.

Description

Technical field [0001] The invention relates to a mold for automobile parts, in particular to a drawing mold for automobile roof parts. Background technique [0002] The current automobile market is frequently updated, and the research and development cycle and market life of automobiles are getting shorter and shorter, which poses severe challenges to the accompanying parts and molds. [0003] The upper molds of the drawing molds of the existing automobile roof parts are all used double-action presses, which puts forward high requirements on the manufacturing of the molds, which often lead to complex mold manufacturing processes, long manufacturing cycles, and high requirements for equipment , The maintenance is cumbersome and the interchangeability of the equipment is poor. On the other hand, the R angle and other materials are prone to picking, cracking, and dark cracking, and the scrap rate is high. Summary of the invention [0004] The purpose of the present invention is to p...
