（毕业设计论文）肥皂盒的塑料注塑模具的设计.doc

摘 要 本文是关于肥皂盒的塑料注塑模具的设计，在正确分析塑件的结构，技术要求及企业的生产实际情况后进行塑件的注射模设计。分别对聚苯乙烯的性能，塑件结构特点分析后，采用了侧浇口进行浇注，以及注射机的选用，分型面的选择，型腔数目的确定，成型零部件的结构设计以及相关的计算，并配有图例来加以说明。采用CAD软件对模具进行辅助设计、分析、绘图。其核心知识是塑料成型、材料成型技术基础、塑料成型工艺、计算机辅助设计、模具CAD等。 通过本次设计，可以对注射模具有一个初步完整的认识，注意到设计中的一些细节问题，如制作的结构、成型零部件的尺寸计算，了解模具结构及工作原理；设计中对注射机相关重要参数进行验证，包括模具闭合厚度、模具安装尺寸、模具开模行程、注射机的锁模等。校核合格后，进行成型零件加工工艺过程的制定，既要保证塑件的质量，又要兼顾经济性。 关键字：聚苯乙烯（PS），注射模，肥皂盒，浇注系统，分型面 ABSTRACT This article is about the soapbox mold design, plastic parts in the correct analysis of the structure, technical requirements and actual situation of production after the injection mold plastic parts design. Respectively Polypropylene performance analysis of structural characteristics of plastic parts, the use of points for pouring gate, as well as the choice of injection machine, the choice of parting surface, the determination of the number of cavity, forming the structural design of components, with a legend to be described. The use of CAD software for mold design, analysis, graphics. The core knowledge is the plastic mold, molding material and technological base, and mechanical design, plastic molding technology, computer-aided design, CAD, such as mold. Through this design may to cast the mold to have a preliminary understanding, notes in the design certain detail question, understands the mold structure and the principle work, The design should be certification, Primarily related to the injection machine of important parameters the certification including die close thickness sizes, the name distance, injection machine of the die drae force and so on. After checking qualified , the molding parts machining process design must ensure that the quality of Supervision taking into account the economy. KEY WORDS：polystyrene，injection mold, soapbox , pouring system, parting surface 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc328000502 第1章 绪 论 PAGEREF _Toc328000502 \h 1 HYPERLINK \l _Toc328000503 1.1塑料的组成及特性 PAGEREF _Toc328000503 \h 3 HYPERLINK \l _Toc3280005
