摘　　要：PLC控制器塑料化设计开发中,重点是控制平面度和安装孔轴线偏离。采用仿真模拟技术计算PLC控制器注塑成型后的平面度和轴线偏离,设计正交试验,探究工艺参数的影响及优化方案。正交试验结果表明:不同工艺参数组合下的PLC控制器平面度和轴线偏离的极大值是极小值的2.5倍和1.8倍,说明工艺参数的影响较大。综合考虑平面度及轴线偏离,最优的工艺参数为A_(2)B_(2)C_(3)D_(1)。优化工艺的仿真模拟结果表明:主要外观面上的缩痕估算、气穴满足要求,注射压力及锁模力也在正常范围,验证了优化工艺的可行性。In the plastic design and development of PLC controllers,the key is to control the flatness and deviation of the installation hole axis.The article uses simulation technology to calculate the flatness and axis deviation of the PLC controller after injection molding,and designs orthogonal tests to explore the influence of process parameters and optimization schemes.The orthogonal test results indicate that the maximum values of the flatness and axis deviation of the PLC controller under different combinations of process parameters are 2.5 times and 1.8 times of the minimum values,respectively,indicating that the influence of process parameters is significant.Taking into account the flatness or axis deviation,the optimal process parameter is A_(2)B_(2)C_(3)D_(1).The simulation results of the optimized process show that the shrinkage estimation and gas cavity on the main appearance surface meet the requirements,and the injection pressure and clamping force are also within the normal range,verifying the feasibility of the optimized process.
