Injection Mold Running System Optimal Design of Lampshade Part Based on Moldflow

2012 
In order to solve the questions of long cycle, high cost, one time success rate and etc during the mold design, polymer rhelolgy theory is introduced. Power-law equation is used to describe the rheological behavior of pseudoplastic fluid. The location of gate is optimized in Moldflow and several modeling schemes are listed. With the help of the filling time analysis, cavity pressure analysis, injection mouth pressure curve analysis and flow front temperature analysis, scheme with best gate location and runner system is confirmed.
