摘　　要：采用信噪比法,以非球面透镜的翘曲变形、折射指数变化、体积收缩率为实验目标,注射时间、保压时间、冷却时间、压缩距离、压缩力、压缩时间、压缩延时时间为实验因素,对透镜的注射压缩成型过程采用Moldflow 2015软件进行模拟与透光率测试。结果表明:最优工艺参数组合为A2B2C3D3E2F1G3,经过优化后透镜的最大翘曲变形量为0.0125 mm,透镜折射指数变化和体积收缩率比优化前分别减小63%和39%,优化前透镜的透光率76.3%,优化后透光率81.8%,通过信噪比法对注射压缩成型工艺参数的优化,可以有效提高非球面透镜的成型质量和光学性能。Using signal-to-noise ratio method, warpage deformation, refractive index variation and volume shrinkage of aspheric lens as experiment objective ,and injection time,holding time,cooling time, compression distance, compression force, eompression time and compression delay time as experiment factor, injection compression molding process for leus was simulated through Moldflow 2015 software, including light transmittance test. The results showed that optimum process parameter was A2B2C3D3E2F1G3, maximum warpage deformations alter optimization was O. 0125 mm respectively, and refractive index variation and volume shrinkage reduced 63% and 39% respectively in comparison with those belore optimization. Light transmittances before optimization and after optimization were 76.3% and 81.8% respectively. Processing quality and opticai property of aspheric lens were improved effeetively through the optimization of signal-to-noise ratio methtul for injection compression molding process parameter.
