In other embodiments, the track assembly 3 can be connected to the bed 1 by screws or bolts.

[0022] See also Figure 1 and Figure 2 A supporting plate 41 is rotatably connected to the supporting platform 4, and the rotation axis of the supporting plate 41 is horizontal. The rotation axis of the supporting plate 41 is perpendicular to the distribution direction of the corresponding track assembly 3 and the cooling pool 2. The rotation axis of the supporting plate 41 is located on the side of the center of gravity of the supporting plate 41 close to the cooling pool 2. A supporting surface is formed on the supporting platform 4, and the supporting surface is located on the side of the supporting plate 41 rotation axis away from the cooling pool 2. The supporting surface abuts the supporting plate 41 to limit the rotation direction of the supporting plate 41. The supporting plate 41 supports the wheel hub blank, and the end of the supporting plate 41 close to the cooling pool 2 is located on the side of the supporting platform 4 close to the cooling pool 2. The supporting plate 41 is rotated downward in the direction close to the cooling pool 2 until it is tilted, and the wheel hub blank on the supporting plate 41 can be poured out.

[0023] Reference Figure 1 and Figure 2 The support platform 4 is provided with an installation chamber 43. The support plate 41 is located above the installation chamber 43 and covers the upper end of the installation chamber 43. The support plate 41 is provided with a plurality of through holes 411 at equal intervals, which are in communication with the installation chamber 43. A fan 412 is fixed to the support plate 41 and is located below the support plate 41. The fan 412 is located on the side of the rotation axis of the support plate 41 away from the cooling pool 2. The fan 412 is located in the installation chamber 43. The air inlet and air outlet of the fan 412 extend in directions perpendicular to each other. The air inlet of the fan 412 is located on the side of the fan 412 away from the support plate 41. The fan 412 is used to pre-cool the wheel hub blank.

[0024] See also Figure 1, a number of water taps 21 are fixed on the cooling pool 2, and the water taps 21 are arranged around the outer circumference of the cooling pool 2. The position and number of the track assembly 3 correspond to the position and number of the water taps 21. The track assembly 3 includes a cooling channel 31 and a guide rail 32. The cooling channel 31 is placed on the bed 1. The cooling channel 31 is positioned by the friction between the bed 1 and the cooling channel 31. The cooling channel 31 is used to hold the cooling liquid. The cooling channel 31 is located below the corresponding water tap 21. A water outlet 211 is provided on the water tap 21, and the water outlet 211 connects the cooling pool 2 and the cooling channel 31. The guide rail 32 is located above the cooling channel 31, and the guide rail 32 is fixedly connected to the cooling channel 31. The projection of the guide rail 32 in the vertical direction is located in the cooling channel 31. The support platform 4 is located above the guide rail 32, and the support platform 4 is slidably connected to the guide rail 32.

[0025] See also Figure 1 and Figure 2 The air inlet of the fan 412 is close to the coolant, and a plurality of ventilation holes 44 are opened on the side of the support platform 4 close to the cooling channel 31. The ventilation holes 44 are connected with the inside of the cooling channel 31, so that the fan 412 can transfer the cold air near the cooling channel 31 to the hub blank to improve the pre-cooling effect.

[0026] During actual production, the track assembly 3 is installed according to the location and number of casting presses, allowing the cast wheel hub blank to land on the support plate 41. The drive assembly 5 drives the support platform 4 to move, driving the wheel hub blank toward the cooling pool 2. During this movement, the fan 412 is activated to pre-cool the wheel hub blank, which helps reduce the thermal stress generated during the quenching process and, in turn, reduces the deformation and cracking tendency of the parts. Furthermore, when attachments on the wheel hub blank surface fall off, they can be swept off the support plate into the cooling channel 31 using tools for later centralized processing. Providing multiple track assemblies 3 helps improve production efficiency.

[0027] See also Figure 1 The position and number of the drive components 5 correspond to the position and number of the support platforms 4, and the drive components 5 drive the corresponding support platforms 4 to move. The drive component 5 includes a drive member 51 and a reciprocating screw 52. The drive member 51 is fixed to the cooling pool 2 and is located above the bed 1. The reciprocating screw 52 is coaxially connected to the drive member 51. The reciprocating screw 52 passes through the corresponding support platform 4 and is threadedly connected to the support platform 4. The drive member 51 drives the reciprocating screw 52 to rotate, thereby driving the support platform 4 to move. In this embodiment, the drive member 51 is a drive motor. In other embodiments, the drive component 5 can also be a telescopic cylinder and a connector.

[0028] See also Figure 1 and Figure 2A driving plate 413 is fixed to the support plate 41. The driving plate 413 is located below the support plate 41. The driving plate 413 is located on the side of the support plate 41 whose rotation axis is close to the water tap 21. The fan 412 is located on the side of the support plate 41 whose rotation axis is away from the water tap 21. The water tap 21 protrudes from the cooling pool 2 and is located in the movement path of the driving plate 413. The water tap 21 is used to abut the driving plate 413 to cause the support plate 41 to flip. The end of the support plate 41 close to the cooling pool 2 is located on the side of the driving plate 413 close to the cooling pool 2. The distance between the support plate 41 and the driving plate 413 is greater than the length of the water tap 21. When the support plate 41 is horizontal, the end of the driving plate 413 away from the faucet 21 is spaced apart from the support platform 4. When the support plate 41 rotates, the end of the driving plate 413 away from the faucet 21 abuts against the support platform 4 to limit the rotation angle of the support plate 41, while the end of the support platform 4 closer to the faucet 21 abuts against the driving plate 413. The faucet 21 in this embodiment is equipped with an on / off valve.

[0029] After the wheel hub blank is moved closer to the cooling pool 2, the water outlet tap 21 abuts the drive plate 413, and at this time the support plate 41 partially extends above the cooling pool 2; the driving member 51 drives the reciprocating screw 52 to rotate and drives the support platform 4 to continue to move forward, and the water outlet tap 21 abuts the drive plate 413 to drive the support plate 41 to tilt downward in the direction close to the cooling pool 2, thereby causing the wheel hub blank to fall into the cooling pool 2 under the action of gravity for cooling, which is beneficial to reduce the contact between people and the wheel hub blank and improve safety.

[0030] The implementation principle of a cooling device for wheel hub casting in an embodiment of the present application is as follows: in the actual production process, the wheel hub blank after casting is placed on a support plate 41 for transportation. Compared with using a clamping mechanism, the overall force is evenly distributed, which makes the wheel hub blank less likely to be damaged and is conducive to improving product quality.

[0031] The above embodiment is only one of the preferred embodiments of the present invention and is not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes made based on the shape, structure, and principle of the present invention should be included in the scope of protection of the present invention.
