AI Technical Summary

Technical Problem

In the existing cemented carbide extrusion molding process, when the ejector structure exerts a large force, it is easy to leave indentations on the molded part, and secondary processing is required later.

Method used

A cemented carbide extrusion molding device is used to achieve the rotation and flipping of the lower mold through a combination of height adjustment component, damping rotation structure and magnetic ejection structure. The gravity of the molded part is used to assist demolding, reducing the force of the magnetic ejection structure.

🎯Benefits of technology

It effectively reduces the possibility of indentations on molded parts, lowers the defect rate, and simplifies the demolding process.
