A high-efficiency ultra-precision glass lens non-isothermal molding equipment and molding method

Abstract

The invention discloses a high-efficiency ultra-precision glass lens non-isothermal molding equipment and molding method. The purpose is to solve the problem of long molding cycle, low molding efficiency and production efficiency caused by the isothermal molding equipment for hot-molded precision aspheric glass lenses at home and abroad. Short service life of molds, low utilization rate, and high manufacturing cost of workpieces. It includes workbench, lower mold base, upper mold base, pressurized pan-tilt, vacuum cover, vacuum connecting pipe, etc. The present invention has the characteristics of parallel heating, molding, annealing and cooling processes, increases the production efficiency to 2 to 3 times the original, and can reduce the temperature difference fluctuation of the mold in each cycle from more than 500 degrees Celsius to 80 degrees Celsius, effectively Reduce the cold and heat fatigue of the mold, significantly prolong the service life of the mold, improve the utilization rate of the mold, greatly reduce the processing cost of the workpiece, and advance the mass production of aspheric glass lenses a big step forward, with significant economic value and Social benefits, broad market prospects.

Description
