【摘要】 介绍了一种基于逆向工程技术的塑料制品模具数字化设计方法,并以某电风扇外壳模具设计为例进行说明.在模具设计过程中,先借助三维扫描仪采集电风扇外壳表面点云数据,然后应用Geomagic Studio软件和UG软件进行数据处理、曲面重构和模型重建,最后用UG软件中MoldWizard模块完成该产品的成型工艺与模具设计.实践表明,此方法对于曲面形状复杂、缺少原始几何数据的塑料产品模具设计具有参考意义,能提高设计的效率和可靠性.更多还原

【Abstract】 Taking the shell of an electrical fan as example,a kind of digital design method of plastic mold based on reverse engineering technology is introduced.In the process of mold design,by means of 3dscanner,the surface point cloud data collection work is completed.The point cloud data processing and surface reconstruction are finished by Geomagic and UG.Finally,the injection mold is designed by UG and its MoldWizard module.The result shows that the efficiency and reliability can be improved,especially for the plastic products with complex shape and original geometrical data.更多还原
