Abstract

Glass molding technology has become a popular solution for the precision manufacturing of the lens. Because of the shortcomings of traditional technology, my teachers team is developing a non-isothermal glass molding precision based on silicon mold, thus introducing a new problem - silicon mold has plastic deformation, affect the final product. In this paper, through the glass is the only contact with silicon and silicon itself research, found that the relationship between the respective temperature - pressure curve, discover the cause of the deformation of silicon is that the pressure is stronger than it can bear. By comparing the pressure values corresponding to silicon and glass at special temperature points, it is concluded that the temperature distribution of glass in non-isothermal glass molding process is not uniform, and the temperature value of glass molded must be above the Tg temperature value of glass. The conclusion that the temperature range of K9 glass should be above Tg temperature is explained from a new aspect.
