模具毕业设计——基于Moldflow塑料旋钮成型分析.doc

【摘要】 Moldflow软件是美国Moldflow公司的产品，Moldflow的产品用于优化制件和模具设计的整个过程，提供了一个整体解决方案。为了了解塑料制品流动分析的流程、方法及操作技巧，本文通过导入模型、划分网格及网格处理、浇注系统与冷却系统设计、选择分析类型和材料、设置工艺参数、结果分析及优化等方面的内容，结和实际详细介绍了充填分析。流动分析、冷却分析、翘曲分析、收缩分析流道平衡分析等。本课题以实际用的塑料旋钮为研究对象可以培养学生对有限元软件的了解，能通过注塑模拟软件对塑件成型过程进行模拟分析，从而熟悉模流分析的方法，更重要的是让学生学会自己去分析塑料件，从分析结果中查找出现各种缺陷的原因，并且找到解决问题的思路及方法。 【关键词】：塑料旋钮；Moldflow；模流分析；优化 Based on analysis of forming the Moldflow plastics knob Abstract Moldflow software Moldflow in the United States companys products, products are used in optimization of Moldflow parts and the whole process of mold design, provides a whole solution. In order to understand the plastic flow analysis process, method and operation skill, grid and grid was divided by importing the model in this paper, processing, design of gating system and cooling system, type and material selection analysis, setting processing parameters, the results analysis and optimization of content, and actual filling analysis was introduced in detail. Flow, cooling analysis, buckling analysis, contraction flow balance analysis, etc. This topic as the research object in actual use plastic knob can cultivate students understanding of the finite element software, can through the simulation software for plastic injection molding process simulation analysis, to be familiar with the mold flow analysis method, more important is to let students learn to analysis of plastic parts, from the analysis results to find the reasons for various defects, and find the thought and method to solve the problem. 【key words 】: plastic knob; MoldflowFlow analysis;optimization 目录 引言 1 一、零件分析 2 二、软件简介与功能 2 2.1软件简介 2 2.2软件功能 3 三、模型导入 4 四、网格划分 5 4.1网格的类型 5 4.2网格的划分 6 五、网格诊断与修复 7 5.1网格诊断 7 5.2网格修复 8 六、型腔布局 10 七、最佳浇口位置分析 11 7.1交口位置及其特点 11 7.2浇口位置分析 11 八、浇注系统的创建 13 8.1浇注系统介绍 13 8.2浇口的设计 14 8.3点浇口的创建 17 九、成型窗口分析 20 9.1选择分析类型 20 9.2设置注射位置 20 9.3设置工艺参数 20 9.4成型窗口分析结果 21 十、充填分析 22 10.1充填分析简介 22 10.2充填分析的目的 23 10.3充填分析 23 10.4充填分析结果解读 23 10.5充填分析总结 25 十一、流道平衡分析 26 11.1流道平衡分析简介 26 11.2流道平衡分析
