Abstract

The invention belongs to the technical field of molds for automobile post-processing parts, and relates to a hump forming structure of an automobile post-processing cylinder. The bottom surface of the formwork surrounds the inner briquetting block of the upper mold and arranges a plurality of outer briquetting blocks of the upper mold evenly in a circular shape; A mounting groove is respectively provided on the board corresponding to each of the upper mold outer pressing blocks, and a first push-down block and a second push-down block are movable in the mounting grooves, and the first push-down block and the second push-down block are two The first return spring is arranged between them, the upper surface of the first lower fixing plate is provided with a lower outer forming slider and a lower inner forming slider, the first lower pushing block is fixedly connected with the lower outer forming slider, and the second The push-down block is fixedly connected with the lower inner forming slide block. The molding structure can ensure the consistency of the quality of the cylinder and greatly reduce the probability of defective products.

Description

technical field [0001] The invention belongs to the technical field of molds for automobile aftertreatment parts, and relates to a hump forming structure of an automobile aftertreatment cylinder. Background technique [0002] The car after-treatment cylinder is an important component of the car, and the hump structure on the cylinder has an important impact on the sealing effect of the cylinder. In the prior art, the cylinder hump is formed by spinning. This processing method cannot meet the sealing requirements of the cylinder hump. It is urgent to develop a new cylinder hump forming structure. Contents of the invention [0003] In view of the above problems, the present invention provides a hump forming structure of an automobile post-processing cylinder, which can ensure the consistency of the quality of the cylinder and greatly reduce the probability of defective products. [0004] According to the technical solution of the present invention: a hump forming structure ...
