采用计算机仿真技术对某网络安全控制器的注塑成型进行模拟，并对平面度进行优化分析。对比分析中心进胶、长边进胶和短边进胶3种进胶方案的注塑成型结果，确定最优进胶方案为短边进胶。以工艺参数为自变量，平面度为目标变量设计正交试验并进行数据分析。结果表明：保压时间对平面度的影响为极显著，熔体温度与模腔温度对平面度的影响为显著，注射时间对平面度的影响为不显著。最优工艺参数组合为A₃B₁C₃D₁。通过工艺优化，平面度降至1.070 7 mm，相比初始工艺下降28.2%，实际试模结果为合格，验证了此优化工艺的可行性。

Computer simulation technology is used to simulate the injection molding of a network security controller, and the flatness is optimized and analyzed. By comparing and analyzing the injection molding results of three injection schemes: center injection, long-side injection and short-side injection, the optimal injection scheme is short-side injection. Taking process parameters as independent variables and flatness as objective variables, orthogonal test was designed and data was analyzed. The results show that the influence of holding time on flatness is extremely significant, the influence of melt temperature and cavity temperature on flatness is significant, and the influence of injection time on flatness is not significant. The optimum combination of process parameters is A₃B₁C₃D₁. Through process optimization, the flatness is reduced to 1.070 7 mm, which is 28.2% lower than that of the initial process. The actual mold test results are qualified, which verifies the feasibility of this optimized process.
