The invention belongs to the technical field of aluminum alloy wheels and discloses a metal net composite casting aluminum alloy wheel. The alloy wheel comprises a hub blank, wherein a metal net is arranged in the hub blank, an upper film limiting block and a lower film limiting block are arranged on the upper surface and the lower surface of the metal net respectively, and an installation ring is fixedly connected to one side of the surface of the hub blank; a waterproof panel is installed on the outer surface of the installation ring, the waterproof panel is fixedly connected with the installation ring through a plurality of installation screws, and the metal diameter of the metal net is 3-8 mm. By means of the arrangement of the metal net, the wall thickness of a casting blank can be reduced by 2-3 mm on the year-on-year basis, and a problem of internal looseness of a composite part is solved; production efficiency is improved, the product pass rate is improved, and meanwhile, the waterproof panel is installed on the surface of the installation ring, and the waterproof effect on the hub is achieved.
本发明属于铝合金车轮技术领域,公开了一种金属网复合铸造铝合金车轮,包括有轮毂毛坯,所述轮毂毛坯的内部设有金属网,所述金属网的上下表面分别设置有上膜限位块和下膜限位块,所述轮毂毛坯表面的一侧固定连接有安装圈,所述安装圈的外表面安装有防水面板,所述防水面板与安装圈之间通过多个安装螺钉固定连接,所述金属网的金属直径为3mm‑8mm,本发明通过金属网的设置可以使铸坯的壁厚同比减薄2mm‑3mm,有利于减低了复合部位的内部疏松问题,同步提升了生产效率、提高产品合格率,同时在安装圈的表面安装有防水面板,对该轮毂起到防水作用。
