Description

Technical Field

[0001] This utility model belongs to the technical field of tire mold base mold processing tooling, and specifically relates to a processing tooling with a repeatable positioning structure. Background Technology

[0002] The tire mold base mold is the fundamental mold component used to form tires in tire production. It is typically made of high-quality steel and designed to withstand the high temperatures and pressures of the vulcanization process. The base mold contains the inner and outer contours of the tire, ensuring that the new tire achieves the correct dimensions and structure during vulcanization. The tire mold base mold requires multiple machining steps during production. To improve processing efficiency, various machining fixtures are often used to clamp and fix it. However, most common machining fixtures lack repeatable positioning structures. During the processing of tire mold base molds in the same batch, operators need to repeatedly move the clamping parts, and each move results in different positions. This leads to inconsistent clamping forces on the tire mold base mold. Over-clamping may consume excessive force, and similarly, excessive force is required during subsequent loosening. Insufficient clamping force may cause the tire mold base mold to shift during processing, resulting in quality issues.
