摘　　要：为快速响应市场、提高研发效率,对某铝合金信号放大器外壳进行逆向建模和压铸模具设计。首先采用ATOS蓝色激光扫描系统进行测量,然后应用Geomagic Design X(杰魔)软件对测量所得点云数据进行处理和逆向建模;根据逆向所得原型进行压铸工艺分析后,结合压铸模具设计理论及经验对该产品进行压铸模具设计。研究过程表明,采用基于激光扫描和杰魔结合的逆向建模方法建模快捷、尺寸准确,通过产品逆向设计和经验的模具设计方法能快速研发出新产品及其压铸模具。In the study,reverse modeling of an aluminum alloy signal amplifier shell and its die-casting die design were carried out to respond quickly to the market and improve R&D efficiency.Firstly,the measurement was done by using the ATOS blue laser scanning system,and then the point cloud data was processed and reverse modeling was carried out by the Geomagic Design X software.After the die casting process was analyzed,the die casting die was designed according to the reverse-derived prototype combining with the die casting die design theory and experience.The study process shows that the reverse modeling method based on the combination of laser scanning and Geomagic is effective and accurate,and the new product and its die casting die can be quickly developed through product reverse design and experienced method of die design.
