Abstract

The invention relates to a mold for a vehicle support part. The mold comprises a lower mold base and an upper mold base; a drawing unit, a trimming and punching unit, a flanging and shaping unit and a punching and separation unit are arranged between the upper mold base and the lower mold base in a strip moving direction in sequence; and the flanging and shaping unit includes a first flanging and shaping mechanism and a second flanging and shaping mechanism arranged in the strip moving direction in sequence. Compared with the prior art, four procedures of drawing, trimming and punching, flanging and shaping and punching and separation are combined, and can be synchronously performed in each punching, so that three pairs of molds are saved, three punching times are reduced, machine tools and staff are saved, the production cost and the maintenance cost are reduced, and the production efficiency is improved; and the structural machinability is excellent, so that the part production precision and stability are guaranteed, and the effects of safety and reliability are achieved.

Description

technical field [0001] The invention belongs to the technical field of auto parts production, and relates to a mold for supporting parts of an auto. Background technique [0002] Car support is an indispensable part of the car body, and its quality stability plays a particularly important role in car safety. Previously, this type of mold was divided into 4 processes, which were drawing, trimming and punching, flanging and shaping, and punching separation. During production, four punches were required, requiring a large number of operators, the production efficiency was not high, and the quality of the parts was not enough. Stablize. [0003] Authorized announcement number is the Chinese invention patent of CN103182445B has announced a kind of mold of automobile tailgate part, comprises lower mold and upper mold, and described lower mold comprises lower mold base, lower mold core and ejector, and described lower mold The core and the ejector are arranged on the lower mold b...
