The invention relates to a semi-solid aluminum alloy steering knuckle, a manufacturing method and a vehicle, and the manufacturing method comprises the following steps: injecting slurry of semi-solid aluminum alloy into a mold, and carrying out die-casting molding to obtain a steering knuckle blank; wherein a sealing plate is arranged on the mold, so that a mounting arm connecting hole in the steering knuckle blank becomes a blind hole with one open end and the other closed end; the steering knuckle blank is machined, so that the blind hole becomes a through hole; and after-treatment continues to be conducted, and the semi-solid aluminum alloy steering knuckle is obtained. In order to overcome the welding defect of the steering knuckle connecting hole, the die is improved to a certain degree, so that an original die-cast through hole is changed into a semi-closed blind hole, slurry of the semi-solid aluminum alloy at the position does not have large-area intersection at a part body, but is pushed forwards in sequence, and the welding quality of the steering knuckle connecting hole is improved. In this way, welding defects are avoided and even eliminated.
本申请涉及一种半固态铝合金转向节、制造方法及车辆,其包括如下步骤:将半固态铝合金的浆料压射到模具中,并压铸成型,以得到转向节毛坯;其中,在所述模具上设置封板,以使所述转向节毛坯上的安装臂连接孔成为一端开口且另一端封闭的盲孔;对所述转向节毛坯进行机加工,以使所述盲孔成为通孔;继续进行后处理,以得到半固态铝合金转向节。针对转向节连接孔出现焊合缺陷,本申请对模具进行了一定的改进,使得原来压铸成型的通孔变成了半封闭的盲孔,使得此处半固态铝合金的浆料未在零件本体处有大面积交汇,而是顺序向前推进,通过这种方式避免形成甚至消除焊合缺陷。
