Description

Technical Field

[0001] The utility model belongs to the technical field of molds, and in particular relates to a cold heading mold for an end cover of a shock absorber. Background Art

[0002] The shock absorber end cap is an important part of the shock absorber. It usually has the following functions: first, it acts as a seal to prevent the oil inside the shock absorber from leaking; second, it provides a foundation for the installation and fixation of other parts of the shock absorber; third, it protects the internal structure of the shock absorber from the influence of external debris to a certain extent. The quality and performance of the shock absorber end cap have an important impact on the overall effect and service life of the shock absorber. It is usually made of metal materials and needs to have certain strength, corrosion resistance and wear resistance.

[0003] The problem with the prior art is that some small molds do not have a mechanism such as a cylinder to drive the upper mold to separate from the lower mold. Therefore, when the work is completed, the upper mold and the lower mold are generally separated manually to demold the workpiece. Although this method can also complete the separation operation, the operation process is too cumbersome and does not save time and effort for the staff. Therefore, we propose a cold heading mold for the shock absorber end cover. Utility Model Content
