摘要
基于CFD数值模拟软件Solidworks Flow Simulation,采用流固耦合传热分析方法对吹塑浮子模具冷却水路进行数值模拟,解决了模具冷却系统结构设计问题。结合响应面优化方法,分析了冷却水入口温度、冷却水入口速度、水路直径3个参数对浮子温度的影响规律,以浮子脱模时的温度最小为目标,得到了最佳的冷却系统参数组合。结果表明:当冷却水入口温度为13℃,冷却水入口速度为2m/s,水路直径为0.012m时,浮子脱模时的最大温度为41.19℃,与原始方案相比,温度降低了30.6%,内表面最大温度为37.12℃,比原始方案降低了28.9%。经生产验证,使用该冷却系统参数可以提高生产效率,缩短了产品成型周期与模具开发周期.
The design problem with the cooling system of the extrusion blow molding float mould was solved by using the fluid-solid coupled heat transfer analysis method based on CFD software - Solidworks Flow Simulation. The relationships between three parameters including inlet temperature, inlet speed of cooling water, diameter of waterway and float outtemperature were simulated. Combined with response surface analysis method , target with minimum float out-temperature, the best combination of cooling system parameters was achieved. The result showed that when the inlet temperature was 13 %, the inlet velocity was 2 m/s and the diameter of the waterway was 0. 012 m , the out-temperature of the float was 41.19 t , which was 30. 6% lower than the original temperature, and the maximum internal surface temperature was 37. 12 ℃, which was 28. 9% lower than the original temperature. The actual production showed that the combination of parameter could increase the production efficiency and shorten the molding cycle.
