Abstract：According to the practical requirement and the structural feature of the hanging rack on a type aircraft and the casting properties of Al alloy ZL205,the sand casting process of the hanging rack made of ZL205 was discussed and analysed.The results show that vertical casting make the parts have a unified property and chemical composition.Chilling with semimetalic mould lining chiller matched with reasonable riser,make the casting have a compact microstructure and high quality;the 1:3:5 cross sectional area ratio of the sprue,runner and gate and the rational fissure with cushion structure make the molten metal fill stably in the mould cavity,that reduce the secondary oxide inclusion and the invading gas;designing the sand core in entirety make the casting have a stable structure.
