Injection molding process analysis and mould design for charger surface-cover
andbottom-cover PENGGuang-wei
Abstract;Based on the product requirements of the charger face-cover and bottom-cover, a reasonable forming scheme was determined, and an injection mould was designed with four cavities for two products of the chargcr face-cover and bottom-cover respectively. Non-equi librium gating systcm was adopted, and the forming parameters were determined through CAE simulation analysis. With the designed forming scheme and mould, the quality of product and the cfficiency can be guaranteed. The CAE method greatly shortened the product developmentcycle

工程塑料ABS是由A(丙烯腈,20%~ 30%)、B(丁二烯,25%~30%)和S(苯乙烯, 40%~50%)组成的多组分共聚物,其特性主要取决于三种单体的比率及两相中的分子结构,在成分设计上具有很大的灵活性。丙烯使塑料具有较高硬度、耐磨性和耐热性;丁二烯具有

加强柔顺性,保持塑料弹性及耐冲击强度;而苯乙烯使得ABS保持良好的成型性(")。总体说来,ABS具有良好的综合机械性能、电绝缘性能及耐腐蚀性好,易于成型和机械加工,其缺点是不耐有机溶剂,耐气候性差。ABS应用很广,适于制作一般机械零件、仪表外壳及各类电器外壳等。
