[0014] The near-net shape casting production method for aluminum alloy parts for automobiles of the present invention adopts semi-continuous casting molds consistent with the shape and size of forged products, that is, semi-continuous casting molds are designed according to the size requirements of forged products, and are prepared by semi-continuous casting. Produce ingots with the shape close to the same shape as the forged product. Each type of near-net-shaped billet is only for forged products with similar cross-sectional dimensions. The ratio of the cross-sectional area of the ingot to the cross-sectional area of the forged product is 1.35: 1~1.05:1. After the ingot is sliced, it is directly formed by one or two die forgings, which reduces the pre-forging billet using other deformation methods, simplifies the production process and obtains aluminum alloy forged products. In the forging forming stage, the comprehensive utilization rate of aluminum alloy material, that is...
