塑料端盖注射模具设计（含全套CAD图纸）精品.doc

本科毕业设计(论文) 题目：塑料端盖注射模设计 塑料端盖注射模设计 摘要 随着社会的发展，不同品种和功能的塑料的出现，塑料产品与我们的日常生活越来越密切。塑料模具设计对生产与生活也越来越重要。 本次毕业设计的课题为塑料端盖注塑模具设计，主要在对塑件从材料上进行工艺分析，确定分型面及型腔数；完成浇注系统的设计，浇口采用侧浇口；抽芯机构采用斜导柱实现塑件的侧孔成型；脱模机构采用顶杆推出。同时通过合理地选择注射机并对注塑压力、最大注塑量、锁模力、开模行程等相关方面进行校核，进一步保证设计的合理型，并设计温度调节系统和阐述模具装配等方面。 本次设计完成了塑料端盖的生产，此次设计不仅结构简单，生产效率高，而且运动可靠生产成本低。最重要的是适用于人们的生活中。 关键词：端盖注塑模具；分型面；注塑模具；注射机 Plastic end cap injection mold design Abstract With the development of society different varieties and function plastic appearance in our lives, plastic productions have closer to our daily lives. Plastic mold design is more and more important to the production and life. The topic of this graduation design for the plastic end cover injection mold design, mainly in based on the analysis of the molding for plastic parts are made from the raw material analysis, forming characteristics, parting surface selection, the design of the gating system, cooling system design, the core and cavity structure design, launch reset structure design, design of side core-pulling mechanism and the design of steering mechanism and other aspects detailed in this paper, the design of the end cover injection mold process. At the same time, through the rational selection of the injection machine and check the injection pressure, the maximum injection quantity, clamping force, mold opening stroke and other related aspects, further ensuring reasonable design, and design the temperature control system and elaborated the mold assembly. This design completed the production of plastic end cover, it not only has simple structure, but also has high production efficiency and the movement is reliable low production cost.The most important it is suitable for peoples life.
