基于ProE的液晶显示器底座注射模具设计（机械CAD图纸）.doc

图书分类号： 密 级： 摘要 塑料工业飞速发展，塑料制品在日常生活中占据着非常重要的地位。而塑料模具已成为衡量一个国家制造业水平高低的重要标志，并在很大程度上决定着产品的质量，公司的效益。所以主要依靠经验的传统注塑模具设计方法已经无法满足市场的要求。模具CAD/CAM/CAE技术已经成为一种解决设计和制造中各种难题的手段，必将代替传统的模具设计方法。 本次设计过程中，在参考国内外大量文献的基础上基于三维工程软件Pro/E和模流分析软件MoldFlow进行了液晶显示器底座的模型重构以及整套模具设计，并进行了相关的模流分析。本文主要在以下几个方面进行了较为详细的研究： 利用Pro/E进行液晶显示器底座造型设计； 运用Pro/E进行分型面设计，并生成成型零件； 运用Pro/E外挂工具EMX进行标准模架设计包括浇注系统、冷却系统等一系列设 计； 运用MoldFlow对模型进行冷却分析、流动分析、翘曲分析，并根据分析结果对设 计进行优化，最终获得比较合理的设计结果； 在相关计算和分析的基础上完成了液晶显示器底座整幅模具设计。 关键词 Pro/E；模具设计；液晶显示器底座；模流分析 Abstract With the rapid development of the plastics industry, plastic products in daily life occupy a very important position. The plastic mold has become an important indicator of the level of the countrys manufacturing industry and largely determines the quality of the product, the companys benefit. Therefore, the traditional injection mold design mainly rely on the experience does not meet the market demands. Die CAD/CAM/CAE technology has become a solution to various problems in the means of design and manufacture, will replace the traditional mold design. The design process, in reference to the extensive literature at home and abroad based on three-dimensional engineering software Pro/E and mold flow analysis software MoldFlow reconstruct and design the model of the liquid crystal display base and carry out the related mold flow analysis. This article in the following aspects of a more detailed study: 1) Using Pro/E modeling to design the liquid crystal display base; 2) Using Pro/E to sub-surface to design and produce molded parts; 3) Using Pro/E plug-in tool for standard EMX mold design includes gating system, cooling system and a series of design; 4) Using MoldFlow obtain the cooling analysis, flow analysis and warping analysis. Based on the results of the analysis to optimize the design obtain a more reasonable design results; 5) Based on the relevant calculations and analysis, LCD base mold design is completed.
