毕业设计说明书 题 目：插座注塑成形工艺制定及模具设计 学 号： 姓 名： 班 级：2007级（1）班 专 业：机械设计制造及其自动化 指导教师： 学 院：机械工程学院 答辩日期：2011年 月 日 摘 要 目前，随着汽车及轻工业的迅速发展，模具设计制造日益受到人们的广泛关注，已成为一个行业。将高新技术应用于模具设计与制造，已成为快速制造优质模具的有力保证：1）、CAD/DAE/CAM的广泛应用，显示了用信息技术带动和提升模具工业的优越性。在欧美，CAD/DAE/CAM已成为模具企业普遍应用的技术。在CAD的应用方面，已经超越了甩掉图板、二维绘图的初级阶段，目前3D设计已达到了70℅--89℅，PRO/E、UG、CIMATRON等软件的应用很普遍。2）、为了缩短制造周期，提高市场竞争力，普遍采用高速切削加工技术。3）、快速成型技术与快速制模技术获得普遍应用。有SLA、SLS、FDM、LOM等各种类型的快速成型设备。 本文系统介绍了塑件的成形工艺及模具成型结构对塑件质量的影响分析，浇注系统的设计，模具成型部分和总装结构的设计。介绍了PE插座注塑模具设计时要注意的要点，并较多的考虑了模具结构的调整性、易更换性及模具成本。从控制制件尺寸精度出发，对PE插座注塑模的各主要尺寸进行了理论计算，以确定各工作零件的尺寸，从模具设计到零部件的加工工艺以及装配工艺等进行详细的阐述，并应用CAD、CAE等软件进行各重要零件的设计和分析。 关键词：工艺分析 塑件成型 浇注系统 模具结构 Abstract At present, develop with the automobile and the light industry promptness, design for die and mould creates the broad attention accepting people gradually , already becomes a industry. Apply the high and new technology to design for die and mould and fabrication , already become the forceful guarantee making the high grade mould rapidly: CAD/DAE/CAM extensive use 1), the superiority having demonstrated the industry and hoisting to use IT to set a mould in motions. Already become the technology that mould enterprise applies commonly in Europe and America , CAD/DAE/CAM. In the field of the CAD application, have already exceeded the junior stage throwing away drawing board , two-dimensional plotting, 3 D design that the application having already reached 70%- 89% , softwares such as PRO/E , UG , CIMATRON is very common at present. Adopt the quick-cutting processing technology commonly 2), for shortening a manufacturing cycle , improving marketplace competition. 3), the fleetness molding technology and the fleetness moulding technology gain common application. Fleetness molding equipment having various types such as SLA , SLS , FDM , LOM. The molding process of plastic parts, the effect analysis to plastic parts quality caused by molding structure, as well as the casting system desig
