Analysis of injection molding process of paint barrel cap based on Moldex3D
The mold flow analysis software Moldex3D was used to simulate the injection molding process of the paint barrel lid,and the difference between the valve-type hot runner and the open-type hot runner for lid mold was studied to design the hot runner combined with simulation results.The factors and levels of Taguchi DOE experiment were designed to optimize the injection molding process parameters.The results show that when the process parameters are set as melt temperature of 250℃,holding time of 2 s and cooling time of 18 s,the product has no appearance quality problems such as short shot and air traps.The optimized injection molding process parameters effectively reduce the cooling time of the product.
