Aiming at the problems in difficult to precisely control the shape in injection molding process of compressor resin blade

which was used in aero-engine compressor low-speed test bench

the optimization of mould cavity was perfomed.The injection process of compressor resin blade was simulated by the Moldflow software

and the warping deformation displacement of the resin blade was presented.Furthermore

using the anti-deformation method with introducing the weight

optimization of the mould cavity and simulation verification were carried out.The results show that it can significantly improve the precision of compressor resin blade in injection molding process by using the anti-deformation method based on the weight way.
