AI Technical Summary

Technical Problem

In the existing technology, the wax molding efficiency of gate valve body is not high. Traditional mold cooling methods consume manpower and time, the equipment is prone to wear and tear, there are safety risks, and the accuracy of the wax mold is affected.

Method used

A gate valve body wax mold forming mold system is provided, which uses a cooling pipe to directly spray the cooling medium. After the cooling medium absorbs heat on the mold surface, it flows into the mold support plate and merges into the sedimentation tank. Combined with the sliding seat and guide rod structure, the mold is cooled in a fixed position, reducing manual handling and equipment transfer.

Benefits of technology

It improves the efficiency of wax mold forming, reduces the efficiency loss of manual handling, lowers the risk of equipment wear, ensures the accuracy and safety of wax molds, and enhances production efficiency and economic benefits.
