Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a combined clamping tooling for mold processing. Background Technology

[0002] In traditional machining, assembly, and inspection fields, workpiece clamping usually relies on special tooling. This type of tooling is designed for specific products or processes and has a fixed and simple structure. When products are updated or different specifications of workpieces need to be processed, the original special tooling is often unable to adapt and must be redesigned, manufactured, and debugged. This results in long production preparation cycles, high costs, complex tooling management, and a large amount of storage space. Therefore, a clamping solution that can quickly adapt to different workpiece shapes, sizes, and process requirements is needed.

[0003] Traditional mold processing relies on specialized fixtures, and repeated customization for specific molds is time-consuming and labor-intensive. Faced with molds with varied shapes and small-batch trial production, there is an urgent need for efficient and universal clamping solutions that can be flexibly reconfigured and adapted to different sizes and structures. However, although existing modular tooling improves versatility, the accuracy error between modules is large and the reconfiguration efficiency is still low, making it difficult to meet the high-precision, efficient production changeover and stable clamping requirements of complex irregular parts.
