武汉纺织大学 毕业设计（论文） 课题名称： 三通管注塑模具设计 姓 名： 宋先伟 院 系： 机械工程与自动化 专 业： 机械设计制造及其自动化 班 级： 机械类11109班 指导教师: 肖晓峰 摘 要 模具工业是国民经济的基础工业，而塑料模具又是整个模具行业的霸主。本次设计的是聚氯乙烯塑件（三通管），三通管作为一种连接件在日常生活中得到广泛应用。本文主要介绍了三通管注塑模具的设计过程。通过对塑件的工艺分析，确定其主要成型工艺参数，设计了三通管注塑模具中的各个系统，如浇注系统、导向与定位机构、侧向分型和抽芯机构、脱模机构、分型面、冷却系统及排气系统等，并对所选用的注塑机参数进行了校核，最后绘制出模具的装配总图，完成本文的编写。该注塑模具为双分型面结构，一模一腔，利用推杆将塑件脱出，结构合理，运行可靠。整个设计过程不仅使用了传统的设计方法，还运用了CAD、PRO/E等技术，大大提高了设计的效率，符合实际应用，能够生产结构合理、精度高、表面质量好的塑料模具；并能加强对注塑模具成型原理的理解，同时锻炼了注塑模具设计和制造能力。 关键词：三通管； 注射模； 型腔； 型芯； CAD ABSTRACT The mold industry is the national economical foundation and the plastic mold is also the overlord in the entire mold industry. The design is plastic parts of HPVC. Three-way Pipe Injection Mold Design Abstract. The three-way pipe as a connection in daily life is used widely. This paper introduces the process of the three-way pipe injection mold design. Through to the analysis of the technology of plastic parts, determine its main molding process parameters, the design of injection mould three-way pipe each of the system, such as gating system, orientation and the position of the institutions, side parting and core-pulling mechanism, ejection mechanism, the parting surface, cooling systems and exhaust slot. And checked the selected injection molding machine parameters, finally draw mold assembly drawing, completes the preparation. This injection mold is two joint surfaces structure, dying structure adopted one module one cavity ,using the push rod plastic parts prolapse. It is a reasonable structure, reliable operation. The whole design process not only using traditional design method, still use of the CAD, PRO / E improving the design efficiency. The design is reasonable and it can produce right construction, high precision, well surface quality plastic mold. And the design of injection mould can strengthen the understanding of forming principle, while exercising the injection molding design an
