AI Technical Summary

Technical Problem

Traditional mechanical parts casting molds have low venting efficiency and lack effective backflow prevention, which makes the castings prone to defects such as porosity, insufficient positioning accuracy, unreasonable connection structure, high maintenance cost, and serious environmental pollution.

Method used

A mold structure including a lower template, a lower mold frame, an upper template, an upper mold frame, an overflow component, and an exhaust box is designed. Through the combination of overflow grooves, overflow columns, and an exhaust box, efficient exhaust and one-way backflow prevention are achieved. Threaded connections and an integral molding structure are used to improve the stability of the components, and a mesh filter is set to prevent contamination.

Benefits of technology

It improves the forming quality of castings, reduces porosity and shrinkage, lowers scrap rate and production costs, enhances the structural stability and service life of molds, and ensures environmental performance and positioning accuracy.
