Problems solved by technology

[0002] The structure of the hinge support parts on the automobile is complicated. At present, the production of this kind of parts needs to go through three punching times, such as punching side shaping, flanging shaping, and punching side shaping, which requires a large number of operators, high manufacturing cost and long manufacturing cycle. , the production efficiency is not high
The existing upper mold presser uses spring or nitrogen spring as the power source, and the spring or nitrogen spring will be damaged normally and require regular replacement, and the maintenance and replacement costs during the production process will be greatly increased

Description

technical field [0001] The invention relates to a mold for producing auto parts, in particular to a mold for an automotive upper hinge support part. Background technique [0002] The structure of the hinge support parts on the automobile is complicated. At present, the production of this kind of parts needs to go through three punching times, such as punching side shaping, flanging shaping, and punching side shaping, which requires a large number of operators, high manufacturing cost and long manufacturing cycle. , the production efficiency is not high. The existing upper mold presser uses a spring or nitrogen spring as a power source, and the spring or nitrogen spring will be damaged normally and requires regular replacement, and the maintenance and replacement costs during the production process will be greatly increased. Contents of the invention [0003] The object of the present invention is to provide a low production cost and easy maintenance part mold for the uppe...
