Embodiment 1
[0023] figure 1 It is a structural schematic diagram of the low-pressure casting mold for an aluminum wheel hub of an automobile provided in this embodiment. As shown in the figure, the low-pressure casting mold for an aluminum wheel hub of an automobile includes an upper mold 1, a lower mold 2, a side mold 3 and a cooling system for cooling the mold. The cooling system includes an upper mold cooling device, a lower mold cooling device and a hot joint cooling device used for cooling the positions of casting hot joints. Among them, the positions of casting hot joints include the front hanger, the rear hanger, the front safety flange, and the rear safety flange. Heat section cooling devices can be arranged near the front suspension and / or the rear suspension and / or the front safety flange and / or the rear safety flange.
[0024] In this embodiment, the hot section cooling device includes the upper mold rear hanging cooling device 4 , the side mold rear hanging complete ring coo...

The invention relates to the technical field of automobile wheel hub dies, and discloses a low-pressure casting die for an automobile aluminum wheel hub. The low-pressure casting die is designed for solving the problems that an existing die is long in casting period and an aluminum wheel hub is poor in mechanical performance. The low-pressure casting die for the automobile aluminum wheel hub comprises an upper die, a low die, a side die and a cooling system. The cooling system comprises an upper die cooling device and a lower die cooling device, and further comprises a hot section cooling device close to a front hanging part and / or a back hanging part and / or a front safe flange and / or a back safe flange. The low-pressure casting die for the automobile aluminum wheel hub can meet the progressive solidification condition of a casting under the situation that the number of spokes is not increased and the temperature at the sprue position is not increased, and accordingly the casing period of the aluminum wheel hub is shortened, production efficiency is improved, and the cooling rate of the casting is high, the crystal becomes small, the mechanical performance of the casting is improved, and the structural strength of the aluminum wheel hub can be enhanced.
Description
technical field [0001] The invention relates to a low-pressure casting mold for an aluminum wheel hub of an automobile. Background technique [0002] Automobile wheels are auto parts with safety features, so the requirements for their internal quality are quite strict. During the casting process of the automobile wheel hub, the wall thickness of the spoke corner heat joint and the rear hanger are thick and there are corners, so the heat dissipation is slow during the solidification process. [0003] Existing low-pressure casting molds for automotive aluminum wheels do not have a cooling system at the hot joints of the spoke corners and the rear hanger. Cycle time, low production efficiency; In addition, due to the long solidification time of the internal structure of the product, the crystal grains are large and the mechanical properties are poor, which affects the structural strength of the product. Contents of the invention [0004] The object of the present invention ...
