The low pressure casting die manufacturing of impeller of high-speed fan which has complex curved face and is needed to high precision is so difficult that traditional machining is hard to work and even more hard to reach specification.
高速风扇叶轮曲面复杂,精度要求高,其低压铸造模具制造难度大,传统的切削加工难以进行,更难以达到技术要求。
In order to raise the accuracy rate of mould design, and curtail the mould design cycle, Pro/E which is the professional software of CAD/CAM, is used to set forth the design and research technique of solid model and mould of impeller of high-speed fan by applying solid feature of part module and curved face feature of manufacturing module of powerful three-dimensional model of Pro/E.
为提高模具设计的准确率和缩短模具设计周期,以专业CAD／CAM软件Pro／E为工具,利用其强大三维造型功能中的零件模块实体特性和制造模块曲面特性,阐述了高速风扇叶轮实体模型及模具的设计和研究方法,并解决了利用Pro／E进行高速风扇叶轮模具设计存在的问题。
Be sure of at least 25 mm (0 inches) between tips of fan blades and fan shrou
确认风扇叶轮与风扇罩之间至少有25公厘（0英寸）的间隙。
