[0002] An injection mold is a tool for producing plastic products. It is also a tool that gives plastic products a complete structure and precise dimensions. Injection molding is a processing method used in mass production of certain parts with complex shapes. Specifically, it refers to the process of injecting heated and melted plastic into the mold cavity under high pressure by an injection molding machine, and obtaining a molded product after cooling and solidification.

[0003] Generally speaking, multiple holes such as injection holes, mounting holes, exhaust holes, cooling water holes, guide post holes, lifting holes and ejector holes need to be opened on the injection mold. Therefore, holes may need to be opened on the top surface, bottom surface, both side surfaces and both end surfaces of the injection mold. At present, the existing drilling positioning tooling is all for horizontal positioning and clamping of mold components, which is extremely inflexible to use. It often takes a lot of time to adjust for different drilling positions of the mold, which has low work efficiency and is time-consuming and labor-intensive. Summary of the invention
