摘　　要：针对薄壁风扇叶片在注射成型过程中容易产生熔接痕和气穴等问题,先对风扇叶片的三维结构进行分析,采用对称3点测浇口进胶的方式,运用MoldFlow模流分析软件仿真模拟注射过程中塑料熔体的流动,对流道结构进行优化设计,将熔接痕和气穴减到最小值,为风扇叶片的模具制造和生产工艺提供了参考。In view of the thin wall fan blade is easy to produce the problem, such as weld marks and air pockets in the injection molding process, first, the three-dimensional structure of the fan blade was analyzed, with the use of symmetric triple test runner into glue, injection molding process of plastic melt flow simulation was analyzed by using MoldFlow mold flow analysis software, the runne structure was optimized design, to reduce the weld mark and air pockets to the minimum,to provide the reference for fan blade mold manufacturing and production process.
