- 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.
