Optimization of Injection Mould Cooling Channel Process Parameters

结合响应曲面法和粒子群优化算法研究了注塑模冷却水道的工艺参数优化,使塑料件在一定的模壁温差下,冷却时间最短。将手机后盖的3D模型导入Moldflow中进行网格划分并对其冷却过程进行模拟,结合BoxBehnken试验设计和响应曲面法得到冷却水道工艺参数与冷却时间和模壁温差之间拟合的回归方程,再通过粒子群优化算法,得到最佳冷却水道工艺参数组合即冷却水道距模具型腔表面的距离为8.851 3 mm、冷却水道直径为12 mm,冷却水道之间的距离为11.054 2 mm,通过对优化的组合参数进行模拟,验证了其可行性。

Optimization of injection mould cooling channel process parameters was researched with the response surface method and particle swarm optimization(PSO).The purpose is that cooling time of the plastic part is the shortest in the range of die wall temperature difference.The3D model of the mobile phone cover was introduced into the Moldflow to simulate the cooling process.The regression equations about cooling time and die wall temperature difference with the process parameters were established,through combining a Box-Behnken design and the response surface method.And then the optimum process parameters combination of cooling channel was obtained by PSO.The distance between the cooling channel and the mould cavity surface is8.8513mm,the cooling channel diameter is12mm and the distance between the cooling water channels is11.0542mm.Simulating the combination was to verify feasibility.
