[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-6 As shown, a cooling structure for a wheel hub casting mold includes a clamping mold 1, which is part of the cooling structure and is used to fix and support other parts of the mold. During the casting process, the clamping mold 1 ensures the stability and accuracy of the mold. The clamping mold 1 has an internal vortex channel 2, a structure designed inside the clamping mold 1 to guide the cooling liquid to flow in a vortex manner. The vortex can more effectively mix the cooling liquid and improve cooling efficiency. A liquid inlet atomizing nozzle 3 is installed at one end of the vortex channel 2 to atomize the cooling liquid and spray it into the vortex channel 2. The atomized cooling liquid can be more evenly distributed on the mold. In order to improve the cooling effect, a molding mold 4 is installed on both sides of the clamping mold 1. The molding mold 4 is the part used to form the shape of the wheel hub during the casting process. It is located on both sides of the clamping mold 1 and includes part of the cooling structure. An S-shaped cooling groove 5 is opened inside the molding mold 4. A side atomizing nozzle 6 is provided at one end of the S-shaped cooling groove 5 to atomize the cooling liquid and spray it into the S-shaped cooling groove 5. This helps to further improve the cooling efficiency and uniformity. A combination connecting plate 7 is installed on one side of the clamping mold 1 to connect and fix the internal molding frame 8. It ensures the integrity and stability of the mold. The internal molding frame 8 is assembled on the combination connecting plate 7 to further define and shape the internal structure of the wheel hub.

[0024] The clamping mold 1 has edge molding grooves around its perimeter. This design is likely to enhance the mold's ability to form the wheel hub edge during the casting process, ensuring the shape and dimensional accuracy of the wheel hub edge. The clamping mold 1 has an output connection groove on its outer side. An atomizing guide pipe 101 is embedded in the center of the clamping mold 1. The atomized cooling liquid can more effectively absorb and remove heat, improving cooling efficiency. The atomizing guide pipe 101 is interconnected with the vortex groove 2. The vortex helps to increase the mixing and flow efficiency of the cooling liquid, further improving the cooling effect.

[0025] The mold 4 has an internal arc-shaped plastic surface designed to match the external shape of the wheel hub, ensuring accurate molding of the wheel hub shape during the casting process. The arc-shaped plastic surface may vary depending on the specific design of the wheel hub to meet different production needs. The side atomizing nozzle 6 is fixedly connected to one end of the S-shaped cooling tank 5, allowing the atomized cooling liquid to be distributed more evenly within the S-shaped cooling tank 5, improving cooling efficiency and ensuring uniform cooling of the mold. The other end of the S-shaped cooling tank 5 is fitted with an output connection pipe 501, designed to export the cooling liquid from the S-shaped cooling tank 5 for recycling or discharge. The output connection pipe 501 may be connected to other parts of the cooling system, such as a cooling liquid recovery device or a discharge pipe.

[0026] The vortex groove 2 has threaded connection holes on both sides. This connection method is both strong and reliable, helping to ensure smooth flow of cooling liquid and system stability. The combined connecting plate 7 has a Taiji connecting groove 701 inside, with guide connection holes on both sides. These holes are used to connect and connect different cooling channels. A connecting threaded tube 702 is internally threaded into the guide connection hole. The connecting threaded tube 702 is threadedly connected to the connecting threaded hole. These connecting threaded tubes 702 are fixedly connected to the guide connection hole by threaded connection and extend into the connecting threaded hole of the vortex groove 2, realizing the connection between the vortex groove 2 and the Taiji connecting groove 701. Guide connections are evenly distributed on the outer side of the connecting threaded tube 702. The connecting hole, the guide connecting hole, and the Taiji connecting groove 701 are fixedly connected to each other. The Taiji connecting groove 701 has connecting output holes on both sides. The internal threads of the connecting output holes are connected to the threaded connecting pipe 703. The internal threads of the threaded connecting pipe 703 are installed with the sealing threaded pipe 704. The outer side of the threaded connecting pipe 703 is evenly provided with circulation connecting holes, which pass through the sealing threaded pipe 704. The design details in this description demonstrate the complexity and precision of the cooling system. Through the ingenious combination and connection of components such as the vortex groove 2, the Taiji connecting groove 701, the connecting threaded pipe 702, the threaded connecting pipe 703, and the circulation connecting holes, the efficient circulation and uniform distribution of the cooling liquid are achieved. This design not only improves the cooling efficiency of the casting process, but also helps to ensure the quality and performance of the final product.

[0027] The internal molding frame 8 has a double-layer spiral guide tube 801 fixedly installed inside. One end of the double-layer spiral guide tube 801 is fixedly connected to each other. Both ends of the double-layer spiral guide tube 801 are designed with connecting positioning tubes 802. Fixed installation holes are opened on both sides of the internal molding frame 8. The connecting positioning tube 802 is embedded in the fixed installation hole. The connecting positioning tube 802 is threadedly connected to the threaded connecting tube 703. Flow connection holes are uniformly designed on the outside of the connecting positioning tube 802. The flow connection holes are connected to the circulation connection holes. The design of the internal molding frame 8 and its double-layer spiral guide tube 801 further enhances the complexity and efficiency of the cooling system. Through ingenious component combination and connection method, the uniform distribution and efficient circulation of cooling liquid inside the mold are achieved. This design not only improves the cooling efficiency of the casting process, but also helps to ensure the quality and performance of the final wheel hub product.

[0028] The clamping mold 1 includes a lower mold 11 and an upper mold 12.
