四通接头注塑成型工艺与模具设计.docx

PAGE PAGE I 摘 要 从注塑模具的发展趋势可以看出，在未来模具市场中，注塑模具的发展将远高于其他模具。人类生活已经离不开塑料，随着塑料注塑模具行业的新技术不断涌现，研究塑料制品的成型将会变得十分有意义。 本文研究的是四通接头注塑模具的设计、注塑成型及模流分析。首先分析产品的成型工艺，然后根据产品结构，设计如何分型，及型腔数目，进胶方式。过程中要充分考虑到零件的加工方法，尽量简便精准，并进行相关尺寸的计算和校核，再设计浇注系统，冷却系统，排气系统，脱模机构，侧抽芯机构，导向机构，以及模架的选取。通过CAD，UG ，Moldflow等软件辅助分析设计是否合理，选择合理的工艺参数和设计方案。 关键词：注塑模具；成型工艺；结构设计；加工工艺，侧抽芯机构。 PAGE II PAGE II Abstract From the development trend of plastic mold can be seen, the development of injection mold will be much higher than other mold in the future. Human being can’t be separated from plastic and along with new technologies of plastic injection mold industry constantly emerging, the research on the formation of plastic products will become very meaningful. In this paper, I study the injection molding of the Carrying handle and its moldflow analysis. Firstly, I will analyse the forming process of the product, and then according to the product structure, design how to type, and the number of cavity, and the way of the glue inlet. In the above process must to take the processing methods into account fully, making it as far as possible simple and accurate, calculating and checking the related dimensions. Next, I will determine the design of gating system, cooling system, exhaust system, demoulding mechanism, guiding mechanism, and make a choice about mold. Making the ues of the CAD, UG, Moldflow and other aided analysis software to ensure that the designs is reasonable, and select the reasonable process parameters and design scheme. Key Words：Injection mold; Molding process; Structure design; Processing technology; side core pulling mechanism. 目录 TOC \o 1-3 \h \z \u 摘 要 I Abstract II 1 绪 论 1 1.1 注塑模具设计在国内、外发展的趋势 1 1.2 CAD／CAE／CAM一体化在注塑模具开发中的应用 1 1.3 课题研究的内容及意义 2 1.4 课题研究的方法与措施 3 2 塑件的结构与工艺性能分析 4 2.1塑件设计的基本内容 4 2.1.1 塑件的设计任务 4 2.1.2 塑件设计的要求 5 2.1.3 塑件材料的选取及主要用途 5 2.2 塑件的结构分析 5 2.2.1 脱模斜度 6 2.2.2 塑件的壁厚 6 2.2.3 塑件尺寸及精度 7 2.2.4 塑件表面粗糙度 7 2.3 塑件的成型工艺分析 7 2.3.1
