AI Technical Summary

Technical Problem

Sulfur glass is prone to excessive thickness deviation during the molding process. The existing solutions require additional grinding processes to reduce production efficiency and waste materials.

Method used

A sulfur-based glass molding mold is designed. By determining the size of the upper mold according to the size of the peripheral heating cavity, calculating the minimum height of the upper mold, determining the height of the upper mold, and designing the corresponding mold sleeve and lower mold size according to the size of the upper mold, so as to reduce the chance of the upper mold tilting or offset during the pressing mold.

Benefits of technology

It effectively reduces the thickness deviation after the pressure of sulfur-based glass, improves the thickness deviation accuracy, avoids additional grinding processes, improves production efficiency and reduces the loss rate of the material.
