[0002] A wheel hub, also known as a rim, is a cylindrical part inside the tire used to support the tire and is centrally assembled on the shaft. Common automotive wheel hubs include steel wheel hubs and aluminum alloy wheel hubs. Steel wheel hubs have high strength and are commonly used in large heavy-duty vehicles. However, steel wheel hubs are heavy in mass and have a single appearance, and are gradually being replaced by aluminum alloy wheel hubs. The casting of wheel hubs generally adopts a casting method of die pressing, which is more conducive to the overall forming of the wheel hub.

[0003] In the existing low-pressure casting molds for aluminum alloy wheel hubs, generally, the pressed parts are not easy to demold due to pressing, and generally, external force is used to push the pressing, and direct forming has an impact on the material. Therefore, the utility model provides a low-pressure casting mold for aluminum alloy wheel hubs. Content of the Utility Model
