AI Technical Summary

Technical Problem

Existing hot-press casting molds are prone to porosity defects during the manufacturing process of ceramic heating elements. This is because air is squeezed and agglomerated into bubbles when the fluid fills the mold cavity, and existing technologies are unable to effectively eliminate this problem.

Method used

A mold structure was designed, comprising a support part, a base platform, a base body, a first middle plate, a second middle plate hinge, and a cover plate body. By setting inclined surfaces and grouting grooves in the mold, gas is discharged through the inclined surfaces when grout is injected, thus eliminating air bubbles.

Benefits of technology

This technology effectively eliminates air bubbles during the manufacturing process of ceramic heating elements, improves product quality, and facilitates mold disassembly and cleaning.
