摘 要
模具是工业生产的基础装备,是制造业的基础产业.塑料制品生产企业设备自动化程度高低也成了衡量企业综合实力的重要标志之一,机械手及其自动化成套设备是国内外极受重视的高新技术应用领域。
针对塑料茶杯盖的机构特点,利用大型CAD软件对其进行造型设计,并给出了其相应的模具结构,冷却系统,浇注系统,顶出机构等,最终选择了合适的注塑机。设计过程采用了计算机辅助模具设计,极大地缩短了产品的研发周期,同时也降低了生产成本。分析了塑料茶杯的结构,设计了成型方案,模具成型零件和其他部分的结构,最后完成了模具结构的设计。通过对模具结构分析,结合生产车间现有的设备,对模具结构进行了优化,从而保证了零件加工质量,降低了成本,增加了模具对加工设备的适应性。
本设计针对注塑模具设计与应用的实际状况,从工程实用角度出发,归纳和总结了薄壁塑件注塑模具,精密塑件注塑模具,全自动端子注塑模具,大型注塑模具,叠层注塑模具,自动脱螺纹注塑模具,侧向抽芯注塑模具,气辅注塑模具和双色注塑模具9种典型模具的设计经验与技巧。

Abstract
Mold is the basic equipment of industrial production and the basic industry of manufacturing industry. The degree of equipment automation in plastic products production enterprises has also become one of the important symbols to measure the comprehensive strength of enterprises. Manipulator and its automation complete sets of equipment are highly valued high-tech application fields at home and abroad.
According to the mechanism characteristics of plastic teacup cover, the large CAD software is used to design it, and the corresponding mould structure, cooling system, pouring system, ejection mechanism and so on are given. Finally, the suitable injection molding machine is selected. The design process adopts computer aided die design, which greatly shortens the R & D cycle and reduces the production cost. The structure of plastic teacup is analyzed, the forming scheme, the structure of mould forming parts and other parts are designed, and the design of mould structure is finally completed. Through the analysis of the die structure and the existing equipment in the production workshop, the die structure is optimized, which ensures the processing quality of the parts, reduces the cost and increases the adaptability of the die to the processing equipment.
In view of the actual situation of the design and application of injection mould, this design summarizes and summarizes the design experience and skills of 9 typical molds: thin-walled plastic injection mould, precision plastic injection mould, automatic terminal injection mould, large injection mould, laminated injection mould, automatic de-thread injection mould, lateral core-pulling injection mould, gas-assisted injection mould and two-color injection mould.
