基于ProE的液晶显示器底座注射模具设计 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.
