摘要
非球面透镜以其优越的性能得到市场的青睐,使其制造技术的研究得到业界重视。非球面透镜的体积收缩影响面型精度,从而影响其光学性能。以非球面透镜体积收缩率为质量目标,选取模具温度、熔体温度、保压压力、保压时间、冷却时间5个关键成形工艺参数,设计了L16(45)正交实验矩阵,采用Moldflow分析软件进行虚拟实验研究,结果表明保压压力对制品的体积收缩率影响最大,得到了一组实验优化的工艺参数。
Aspheric surface lens becomes popular in many application fields because of it＇ s superior performance, consequently, the development of aspheric surface lens manufacture technology becomes concerned very much, volumetric shrinkage affects the surface contour of the molded lens and leads to bad optical performance. In this paper, select the volumetric shrinkage of the aspheric surface lens as the research object. The five key factors that affect the volumetric shrinkage of the aspheric surface lens, such as mould temperature, melt temperature, holding pressure, hold pressure time and cooling time are analyzed in Moldflow virtual experiments combined with an L16（45） orthogonal array. The study shows that holding pressure is the principal factor affecting the volumetric shrinkage of the part, and the optimum combinations of processing parameters were also been found in the virtual experiments.
