针对注射成型微透镜特征阵列的复制程度和成型异性,以具有微透镜阵列特征的薄壁导光板为例,运用数值模拟和正交试验法对其进行了翘曲分析.结果表明,中间区域的微透镜特征表现出沿轮廓曲线均匀缩小的变形趋势,而边侧微透镜特征表现出向中心偏移的变形趋势;依据不同的复制程度特征指标,发现熔体温度、进胶流率和模具温度对微透镜特征阵列的复制程度影响较大.%For replication fidelity and anisotropic formation of microlens feature array during injection molding processes,a thin-walled light guide panel with a microlens feature array was taken as an example to perform a warpage analysis by using numerical simulation and orthogonal experiment methods.The results indicated that the deformation trend of microlens features in the middle region exhibit a homogeneous decrease along the contour curve,whereas the deformation tendency of the side microlens features presented a deviation toward the center.According to the different replication characteristics,the melt temperature,flow rate and mold temperature were found to have a great effect on the reproduction fidelity of microlens feature array.
