Computer-implemented composite simulation method and non-transitory computer medium for use in molding process

摘要

A computer-implemented method for use in a molding process by a computer processor includes specifying a simulating domain having a cavity part and a runner part; setting a filling condition of the cavity part without taking into consideration the runner part, wherein the filling condition includes gate pressures and filling rates of the cavities of the cavity part; and performing a steady state analysis to calculate flow conditions of a plurality of runner designs for the runner part by taking into consideration the filling condition of the cavity part, wherein the flow conditions include flow rates of a molding material in the runners of the runner part.

1. A computer-implemented simulation method for use in a molding process by a computer processor, comprising:
specifying a simulating domain having a cavity part and a runner part, wherein the cavity part comprises a first cavity and a second cavity, and the runner part comprises a first runner connected to the first cavity through a first gate and a second runner connected to the second cavity through a second gate; setting a filling condition of the cavity part without taking into consideration the runner part, wherein the filling condition comprises a first gate pressure of the first gate and a first filling rate of the first cavity, and a second gate pressure of the second gate and a second filling rate of the second cavity; performing a steady state analysis to calculate flow conditions of a plurality of runner designs for the runner part by taking into consideration the filling condition of the cavity part, wherein the flow conditions comprise a first flow rate of a molding material in the first runner and a second flow rate of the molding material in the second runner; and setting the filling condition and the flow conditions to on an injection machine using a controller, wherein the setting of the filling condition of the cavity part comprises performing a transient state analysis; the transient state analysis comprises generating a first correlation between the first gate pressure and the first filling rate and generating a second correlation between the second gate pressure and the second filling rate; the transient state analysis comprises setting a filling time of the cavity part by taking into consideration a first minimum pressure of the first correlation and a second minimum pressure of the second correlation; and the transient state analysis comprises changing at least one of the first correlation and the second correlation by taking into consideration that the cavity part has at least one redundant runner.
