Abstract

Aspheric optical elements are increasingly developing towards miniaturization. In the manufacturing process of aspheric lens, it is easy to produce warpage, deformation and other phenomena that affect the optical performance. In this paper, CAE technology is used to model it, and then finite element software is used to analyze its molding process. The effects of melt temperature, mold temperature, injection time, dwell pressure and cooling time on the internal stress of plastic parts are obtained, and the optimal injection parameters are obtained by optimizing the process parameters through orthogonal test. The lens quality is the best when the melt temperature is 300℃, the mold temperature is 80℃, the injection time is 1s, the dwell pressure is 60MPa, and the cooling time is 20s. The simulation results show that the maximum residual stress is 10.18MPa, which meets the requirements of the evaluation index and improves the product quality.
