09-08-13 Design of Injection Mould for DVD Door Panel Based on CAE Technology HUANG Gui-jian~, HONG Jian-ming, LIANG Xiong, WU Xiao-yu, LI Ji-bin （1. College of Mechatronics and Control Engineering, Shenzhen University, Shenzhen 518060, China; 2. School of Mechanical and Electrical Engineering, Shenzhen Polytechnic, Shenzhen518055, China; 3. Shenzhen Key Laboratory of Advanced Mould Manutacturing Technology, Shenzhen University, Shenzhen 5 t 8060, China）
Abstract： The structural feature and forming technology of the DVD door panel were analyzed. By using Moldflow/MPI software, the feed system of the mould was ascertained. The angle pin core-pulling mechanism was adopted and the mechanism set inside the core-pulling slide preventing the plastic parts from adhering to the side core of the mould was designed, so the smooth demoulding of the plastic parts was realized. The structure of the injection mould and working process were discussed. The mould was already in mass production and the plastic parts could meet the customers＇ technical requirements.
