Precision injection-molded plastic optical lenses are extensively utilized in imaging optical systems. Surface deviations produced during the injection molding of plastic optical lenses will immediately result in imaging quality issues. Conventional injection molding often employs an orthogonal experimental procedure to validate the chosen process parameter combination post-molding, necessitating substantial raw materials and time for numerous processes. Therefore, this article proposes a multi section method based on warpage and shrinkage behavior for deformation analysis of optical plastic lens precision injection molding. The deformation of precision injection-molded aspherical plastic optical lens utilized in imaging optical systems was examined via simulation and experimental. The findings demonstrate that the suggested method successfully performs deformation analysis of plastic optical lenses post-injection molding.
精密注塑成型的塑料光学透镜在成像光学系统中得到广泛应用。塑料光学透镜注塑成型过程中产生的表面偏差会直接导致成像质量问题。传统注塑成型通常采用正交实验程序在成型后验证所选工艺参数组合，这需要大量原材料以及大量工序的时间。因此，本文提出一种基于翘曲和收缩行为的多截面方法，用于光学塑料透镜精密注塑成型的变形分析。通过模拟和实验研究了用于成像光学系统的精密注塑成型非球面塑料光学透镜的变形情况。研究结果表明，所提出的方法成功地对注塑成型后的塑料光学透镜进行了变形分析。
