编号： 毕业设计说明书 题 目： 5号电池充电器外壳 底座注塑模设计 学 院： 机电工程学院 专 业： 机械设计制造及其自动化 学生姓名： 韦毅 学 号： 0600110226 指导教师： 刘海浪 职 称： 讲师 题目类型： 理论研究 实验研究 工程设计 工程技术研究 软件开发 2010年 5 月 30 日  摘 要 目前，在模具行业中随着以塑料代钢、以塑代木的发展和产品零件的精度和复杂程度的不断提高，塑料模的比例将不断提高，其精度和复杂程度也将随着相应提高moldflow仿真塑料熔体在型腔内的充模流动和冷却过程分析，更直观的找出设计中可能存在的缺陷，优化了工艺方案及工艺参数，降低了缺陷出现的可能性。利用参数化实体造型的方法，为更加高速、快捷的造型、生产提供了一种切实可行的办法。moldflow仿真 Abstract At present, the plastic mold industry with plasticl instead of the steel, to the development of plastic instead of wood and product parts precision and complexity of the continuous improvement，Plastic Will continue to increase the proportion of plastic molds, the precision and complexity will increase with the corresponding as will,thus, the future of the plastic mold will be very broad. This graduate that design is:The shell of AA battery charger injects the mold. This design primarily passeses to piece viability assessment for request for of shape, size and its accuracy coming proceeding injecting type craft. the piece the wall for of type craft primarily including the piece is thick, slope and circle angle and whether to have core-pulling or not mechanism.Pass the above analysis to come the certain molding tool cent the type the surface, type the number, gate the form, place the size; The among them and most important is a certain type core and the construction of the type. In addition and still analyzed the molding tool to suffer force, mold that design that the design of the pattern draw mechanism, match the design etc. to lead to the mechanism, cooling system. This design used moldflow simulation of plastic melt in the cavity of the mold filling and cooling process analysis, The more intuitive to find the design flaws that may exist, Process and optimized process parameters. Key words：The shell of AA battery charger
