摘要
对注塑模具冷却系统进行传热分析,得出了影响模具冷却的3个主要因素:冷却道的直径、相邻冷却道之间的距离及冷却道距模具表面的距离;改进了传统冷却设计方法,提出了模具随形冷却的"以面到体"设计方法;以台灯后壳为例,设计了模具冷却的均匀性试验和正交试验,并应用Moldflow软件对各组试验进行仿真分析,用直观对比法与极差分析法分析仿真结果,得出最佳试验数据,并同传统冷却进行比较,结果表明,模具温度降低11.40%,翘曲变形量降低9.32%。因此该方法可以明显提高模具冷却系统的冷却效果。
Heat transfer analysis of injection mold cooling system was carried out, the main factors that affected the cooling of the mold were obtained：the diameter of the cooling channel, the distance between the adjacent cooling channel and the distance between the cooling channel and the mold surface. The method of traditional design of cooling was improved and the method of design of＂ face to body＂ was proposed. Take the case of desk lamp shell for example, the uniformity experiment and orthogonal experiment of mold cooling were designed. Simulation experiment were carried out by using Moldflow software. The simulation results were analyzed by visual contrast method and range analysis method, and the best experimental data were obtained. Comparing with the traditional cooling, the results showed that the die temperature was reduced by 11.04% , and the warp deformation was reduced by 9. 32%. Therefore, the method could significantly improve cooling effect of the mold cooling system.
