摘要:

通过对塑料熔体在型腔中流动行为的分析,基于合理的假设建立了等温条件下前峰面熔体在给定时间段内流动长度和型腔厚度的函数关系,并提出了快速预测熔体充填模式的方法,即等效流长法.该法将熔体前峰面的追踪问题转换为带权曲面上任意两点间近似最短路径的求解.短射实验证明,该算法预测的充填模式与实际产品的充填模式符合较好.

Abstract:

Through the analysis of the flow behavior of plastic melt in the cavity, the functional relationship between the flow length and cavity thickness of the front peak melt in a given time period under isothermal conditions is established based on reasonable assumptions, and a method for quickly predicting the melt filling mode is proposed, namely the equivalent flow length method. This method converts the tracking problem of the peak surface before the melt into the solution of the approximate shortest path between any two points on the weighted surface. Short-shot experiments show that the filling mode predicted by the algorithm is in good agreement with the filling mode of the actual product.
