注塑水杯注塑模具论文.docVIP

中文摘要 本次毕业设计课题来源于我们日常生活中用得最多的水杯，本文详细记录水杯注塑模具的设计过程。设计过程包括塑件材料、注塑机、分型面等的选择、塑件结构的分析，注塑模具浇注系统、注塑模具成型零件和模体、注塑模具侧抽芯机构、注塑模具顶杆脱模机构、注塑模具温度调节系统等的设计。综合水杯塑件的结构特点，该模具设计采用了直接浇口、顶针脱模的形式。在粗步设计完注塑模具之后还要对注塑机各项参数进行校核，其中包括注塑机的锁模力、注射机的装模厚度、注射压力、注射机最大开模行程等内容，校核的目的是保证让注射机可以配合模具顺利地工作。本次设计中让我可以综合应用到以前学习到的专业知识，加深我对注射模具设计原理的理解，设计中除了应用传统的计算方法，我还多次使用AuToCAD、soliworks等软件，简化了设计过程，提高了设计精度和效率。 关键词：注塑水杯；浇口；收缩率；脱模 Abstract The graduation design topic originates from the cup is most commonly used in everyday life. The design process of this paper records cup injection mold in detail. The design process includes plastic material selection , plastic parts structure analysis, injection molding machine selection , die joint selection , injection mold for plastics injection system design, plastic injection molding parts and die design , plastic injection mold side core pulling mechanism design, plastic injection mold ejection mechanism design , plastic injection mold temperature control system design , etc. Comprehensive cup plastic structure parts, the design of the mold adopt the form of direct gate and demolding thimble. After designing a mold , all parameters of injection molding section is checked.The contents of checking includes the clamping force of injection molding machines, injection molding machine mold thickness, injection pressure, the maximum opening stroke etc .The purpose of checking is in order to ensure that the injection machine can be matched with the mold to work .This design makes me comprehensive application Ive learned knowledge ,to deepen my understanding of the principles of the design of injection mold .In the design ,I am not only use the traditional calculation method of application but use the software of AutoCAD and SolidWorks times ,which simplify the design process and improve the precision and efficiency of design.
