Description

Technical Field

[0001] The utility model belongs to the technical field of mold parts processing fixtures, in particular to a processing fixture with a shock-absorbing structure. Background Art

[0002] In production and processing, molds are often used for batch production to improve production efficiency and production quality. Molds are assembled from related mold parts. Therefore, mold parts need to be processed in production to manufacture corresponding production molds. In the manufacturing of mold parts, they need to be clamped and fixed to prevent offset and other situations during the processing, resulting in processing deviations. Most common processing fixtures for clamping mold parts only clamp and fix the mold parts on both sides, and the shapes of mold parts are different. This will lead to insufficient clamping firmness in actual production. The special shape of the mold parts may cause unstable clamping at both ends, resulting in processing deviations during the processing, requiring multiple processing corrections, thereby reducing production efficiency. It may also directly lead to the scrapping of raw materials and their inability to continue to be used, which will also reduce overall production efficiency and increase corresponding production costs.

[0003] In summary, there are some problems in the use of a processing fixture that only clamps and fixes the two ends, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
