[0002] This is one of the main usage scenarios. During the wheel hub casting process, the casting temperature is high, and a cooling structure is needed to control the temperature to ensure the quality and shape of the wheel hub casting. The cooling structure is usually arranged inside the wheel hub, and cooling water is provided to the casting wheel hub through a water spray system or other cooling devices to prevent overheating and deformation. Some wheel hub foundries may improve the casting process to improve production efficiency and product quality. By optimizing the cooling structure of the wheel hub inner rim casting, more uniform and effective cooling can be achieved, thereby reducing casting time, saving energy, and improving the internal structure and performance of the wheel hub.

[0025] The bottom of the two insertion plates 12 are provided with a snap-fitting hole 13, and the insertion plates 12 can be fixed by fixing the snap-fitting holes 13. The adjacent sides of the two snap-fitting plates 9 are respectively snap-fitted with the inside of the two snap-fitting holes 13, and the insertion plates 12 can be fixed by snapping the snap-fitting holes 13. An air collecting box 14 is fixedly connected to the middle end of the bottom of the mounting plate 4, and an air pipe 15 is fixedly connected to the bottom of the air collecting box 14, so that the air collecting box 14 can collect the blown-in cooling air, and the air pipe 15 can transport the cooling air. The tops of the two pressing plates 7 respectively penetrate the top inner walls of the two cavities 5 and extend outward, and the bottom of the air pipe 15 penetrates the top of the upper mold 3 and extends inward, so that the cooling air can be input into the interior of the lower mold 2 through the air pipe 15.

[0026] like Figure 1 and Figure 3As shown: a ventilation hole 16 is provided at the top of the rear side of the lower mold 2, so that the internal hot air of the lower mold 2 can be exchanged with the outside for cooling. The front and rear sides of the top of the placement table 1 are fixedly connected with mounting plates 17, so that the placement table 1 can provide support for the mounting plates 17, and the adjacent sides of the two mounting plates 17 are fixedly connected with clamping assemblies, so that the mounting plates 17 can provide support for the clamping assemblies, and the clamping assemblies include two hydraulic rods 18, and the bottoms of the two hydraulic rods 18 are respectively fixedly connected to the tops of the two mounting plates 17.

[0027] Therefore, the mounting plate 17 can provide support for the hydraulic rod 18, and the output ends of the two hydraulic rods 18 are fixedly connected to the clamping plate 19, and then starting the hydraulic rod 18 can make the output end of the hydraulic rod 18 drive the clamping plate 19 to move, and the left and right sides of the top of the placing table 1 are fixedly connected with hydraulic rods 20, so that the placing table 1 can provide support for the hydraulic rods 20, and the tops of the two hydraulic rods 20 are fixedly connected with lifting plates 21, and then starting the hydraulic rod 20 can make its output end drive the lifting plates 21 to move, and the adjacent sides of the two lifting plates 21 are respectively fixedly connected to the left and right sides of the upper mold 3.

[0028] Compared with some existing technologies, the above content enables the device to start the fan 11 during use, so that the fan 11 can blow cooling air into the interior of the air collecting box 14 mounting plate 4, so that the cooling air can enter the interior of the lower mold 2 through the interior of the air supply pipe 15 to cool the wheel hub casting, and the fan 11 can be disassembled and repaired, thereby increasing the service life of the device, and by starting the hydraulic rod 18, the output end of the hydraulic rod 18 can drive the clamping plate 19 to clamp and fix the lower mold 2, thereby preventing the mold from shaking when the wheel hub casting is processed, and by lifting the upper mold 3, it is convenient for the staff to take out the wheel hub casting inside the lower mold 2.

[0029] Working principle: First, when the hub casting inside the lower mold 2 needs to be cooled, the fan 11 can be started to blow cooling air into the air collecting box 14, so that the cooling air will enter the air pipe 15 through the air collecting box 14, and then the cooling air will enter the lower mold 2 through the air pipe 15, so that the hub casting inside the lower mold 2 can be cooled, and the ventilation holes 16 can be used to exchange and cool it with the outside air.

[0030] When the fan 11 has too much dust on the outside due to long-term use, the pressing plate 7 can be pressed to compress the spring 6, so that the pressing plate 7 will drive the connecting plate 8 to move, and the connecting plate 8 will drive the engaging plate 9 to move when moving, and then the engaging plate 9 will disengage from the inside of the engaging hole 13 when moving, so that the insertion plate 12 can be taken out from the inside of the insertion slot 10, and then the fan 11 can be disassembled from the top of the mounting plate 4, which is convenient for the staff to inspect, clean or replace it.
