[摘 要]

本课题是江苏省普通高等院校模具设计与制造专业，专题综合实践项目之一。是对模具专业学生的一次综合考察。
设计者需通过课题的CAD二维工程图纸，进行模具设计。其中包括：产品材料、工艺、结构、尺寸精度分析，成型零件尺寸计算，合理选择注塑机及标准模架。并用CAD2006完成模具总装图及成型零件图的绘制，完成成型零件的加工工艺卡编写等。
本设计主用软件CAD2006，通过CAD2006完成相关元件的二维工程图纸。并结合Pro/ENGINEER4.0进行辅助设计。经过反复修改，最终完成课题设计。

前言

模具制造是我国经济建设中的一项重要产业，起着振兴和发展我国模具工业的重要作用，正日益受到人们的重视和关注。“模具是工业生产的基础工艺装备”也已经成为广大业内人士的共识。在电子、汽车、电机、电器、仪器、仪表、家电和通信等产品中，60%～80%的零部件都要依靠模具成形。用模具生产制件,具备高精度、高复杂程度、高一致性、高生产率和低消耗，是其他加工制造方法所不能比拟的。模具又是“效益放大器”，用模具生产的最终产品的价值，往往是模具自身价值的几十倍、上百倍,尤其是在冲压技术相对落后的中国，制造出优质的模具以及生产出高质量的产品势在必行。
经过本次的课题研究主要掌握模具设计的方法及工序，巩固和加深对机械二维、三维的制图能力。设计过程中锻炼查阅文献和资料、自我设计的能力，培养和提升自己的创新能力，增强独立思考问题和解决问题的能力。在对模具设备的结构设计和理论计算上，掌握模具设备的主要结构与性能、工艺适应性与技术参数。从而能根据成型的生产要求、模具结构等因素，经济、有效的使用设备，合理的选择工艺，正确的设计模具，保证成型生产能够经济、合理的进行，提高自身在成型工艺和模具方面的综合着机水平，提高自身解决实际问题的能力。
   在这次毕业设计过程中，我得到了袁小江老师的指导，他给了我很多意见和建议，使我的设计更加完善，在此特别的感谢他。同时也感谢那些曾经授课的老师，他们使我学习、获得了专业知识，对设计起了重要作用。也要感谢那些帮过我的同学，他们给我提了很多好的建议。

第一章 材料工艺分析

1.1材料特性
ABS无色、无味、呈微黄色。密度为1.02~1.05g/cm³（注射注射级密度为1.05g/cm ³）。具有优越的综合性能：强度高、刚性好，硬度、耐冲击性、制品表面光泽性好，耐磨性好。具有有良的成型加工性，尺寸稳定性好，着色性能、电镀性好。
1.2在模具设计方面需注意：
⑴需要采用较高的料温与模温，浇注系统的流动阻力要小。
⑵注意选择浇口位置，避免浇口与熔接痕位于影响制品外观的部位。
⑶合理设计顶出脱模结构，推出力过大时，制品表面易“发白”、“变混”（顶白）。
