Dong Xiangrfiong, Li Nianwei, Shen Honglei (Sichuan University, Chengdu 610065)
The hot runner technique and the gas-assisted injection molding technique were summarized at first, then a large-scale in- jection mold, producing the front bumper of AOTUO oar, was designed optimally with CAE tool C-MOLD. After the geometry model of 3D including runner system, nozzles and meshes were built, the injection material, machine and process were all assigned. Next, a successful resin injection molding CAE analysis had been accomplished. The results showed that the hot runners, 4 gates, 4 gas channels and 4 nozzles were the best design. In the end, these results also illustrated that the hot runner technique and the gas-assisted injection molding technique can be used in large-scale injection molds completely.
