The invention discloses a casting method of an integrated automobile aluminum alloy chassis and the automobile aluminum alloy chassis, and belongs to the technical field of 3D printing. S2, parting and designing a sand mold; s3, sand mold printing; s4, sand mold treatment and mold closing; s5, closing the sand mold; s6, smelting and casting; and S7, cleaning and detecting the casting. According to the casting process, the 3D sand mold printing technology is combined with traditional gravity casting, casting of the integrated automobile aluminum alloy chassis is achieved, and the casting process of the integrated automobile aluminum alloy chassis is perfected; the problems that a large thin-wall part cannot be cast and formed under the action of gravity, and the size precision and the assembly precision cannot be guaranteed in the casting and forming process are solved. The cost is effectively reduced, the production period is shortened, the production efficiency is improved, and large-scale production is facilitated.

    本发明公开了一体化汽车铝合金底盘的铸造方法及汽车铝合金底盘,属于3D打印技术领域,包括以下步骤:S1、工艺分析和设计;S2、砂型分型和设计;S3、砂型打印;S4、砂型处理和合箱;S5、砂型合模;S6、熔炼铸造;S7、铸件清理、检测。本发明通过3D打印砂型技术结合传统重力铸造,实现一体化汽车铝合金底盘的铸造,完善了一体化汽车铝合金底盘的铸造工艺,解决了大型薄壁件在重力作用下无法铸造成型以及解决了铸造成型过程中无法保证尺寸精度和装配精度的难题。本发明还有效降低成本和减少生产周期,提升生产效能和提高生产效率,有利于实现大规模生产。
