Therefore, the surface temperature of the centrifugal casting machine is relatively high during operation. In order to quickly form the metal parts, a water-cooling structure is required to cool the centrifuge. For example, a multi-station centrifugal casting machine with announcement number CN220992756U relates to the field of centrifugal casting technology, including a casting mechanism, a water-cooling mechanism is fixedly connected to the top of the casting mechanism, and with the cooperation of the casting mechanism, three centrifuges can be installed on the rotating table for simultaneous processing, effectively improving the casting efficiency. The rotating table can also drive the three centrifuges to rotate, making it convenient for staff to monitor the device. A barrel is installed on the top to simultaneously transport raw materials to the bottom, and the centrifuge can be filled at one time to reduce the occurrence of separation. The device is simple and easy to operate.

In addition, the power of the centrifuge's high-speed rotation is not utilized, resulting in a waste of resources.

[0005] 2. After the cooled liquid is collected, its temperature is still high. Due to the lack of a cooling mechanism, the recovered liquid cannot be recycled, and the centrifuge cannot be cooled during recycling.

[0016] Preferably, the output shaft of the motor is driven by meshing with the stirring shaft through a bevel gear set, and the stirring shaft rotates through the storage box, and a cam is fixedly sleeved on the bottom of the output shaft of the motor.

The specific contents are as follows:

[0021] 1. The liquid enters the discharge pipe and is sprayed out from the nozzle, spraying at equal angles on the outside of the forming cylinder to cool it. When the carrier plate rotates at high speed, it can drive the guide block to rotate synchronously. When rotating, it contacts the bottom of the discharge pipe and pushes it up. Since a rubber tube is provided at the upper end of the discharge pipe, its position will change after being pushed. Therefore, when the liquid is sprayed for cooling, the movement of the discharge pipe will increase the liquid spraying range;

[0022] 2. The gas generated by the rotation of the fan blades is transmitted to the outer tube through the gas pipe, and then transmitted to different exhaust pipes respectively, and finally discharged from the air outlet to the outside of the forming cylinder to further cool it. At the same time, the bottom of the exhaust pipe can also contact with the rotating guide block, so that the exhaust pipe can also move up and down during exhaust, thereby increasing the spray range of the gas;

[0023] 3. The motor drives the cam to rotate, and during the rotation, it contacts the fixed block and pushes the fixed plate to move. During the movement, on the one hand, it drives the connecting plate to move, so that the heat dissipation port is open to facilitate the discharge of hot air. On the other hand, it drives the movable plate to move. After the movement, the fixing hole is driven to coincide with the connecting hole on the water tank. The liquid in the storage box can flow into the water tank for recycling. When the fixing hole and the connecting hole are intertwined, the liquid delivery is stopped. In this way, by intermittently delivering part of the liquid to the water tank, the cooling of the heated liquid can be accelerated for subsequent recycling. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See also Figures 1-10 , the present invention provides the following technical solutions:

[0037] Embodiment 1: In order to solve the problems existing in the prior art, this embodiment adopts the following technical scheme: a centrifuge circulating water cooling mechanism for copper casting, comprising a support frame 1, a motor 2 is installed on the side of the support frame 1 by bolts, and the output shaft of the motor 2 is connected to the lower end surface of the carrying plate 3 by a pulley mechanism, a forming cylinder 4 is fixedly provided on the upper end surface of the carrying plate 3, and a sealing cover 5 is provided on the top of the forming cylinder 4, and a feeding port is opened at the center of the sealing cover 5; it also includes: a fixed cylinder 6, which is sleeved on the outside of the forming cylinder 4, the bottom of the fixed cylinder 6 is fixed on the support frame 1, and a liquid cooling mechanism is provided below the fixed cylinder 6, and the liquid cooling mechanism cools the forming cylinder 4 by spraying water; an air cooling mechanism is provided below the motor 2, and the air cooling mechanism further cools the forming cylinder 4 by blowing air; as Figure 1-Figure 3 As shown, the liquid metal is first poured into the interior of the forming cylinder 4 from the feed port in the center of the sealing cover 5, and then the motor 2 drives the supporting plate 3 and the forming cylinder 4 to rotate at high speed through the pulley mechanism, so that the liquid metal is distributed on the inner wall of the forming cylinder 4 and is formed into a copper tube after cooling.

[0038] Most of the existing water cooling mechanisms use water spraying to cool the centrifuge. The cooling efficiency of water spraying alone is low, and there is no combination of water spraying and air blowing to achieve more efficient cooling. Figure 5-Figure 8 and Figure 10As shown, the liquid cooling mechanism includes a water tank 9 fixed to the inner side of the support frame 1, and a water pump 10 is installed inside the water tank 9, and the water pump 10 is communicated with the inner tube 12 through the infusion tube 11, and the inner tube 12 is fixed to the inner top surface of the fixed cylinder 6, the inner tube 12 is annular in structure, and is grid-shaped at the position close to the fixed cylinder 6 and the sealing cover 5; a drainage pipe 13 is fixed at an equal angle below the inner tube 12, and the disconnection at the upper end of the drainage pipe 13 is connected by a rubber tube 14, and the inner tube 12 is communicated with the rubber tube 14 through the drainage pipe 13, and nozzles 15 are arranged at equal intervals on the side of the drainage pipe 13; a storage box 8 is fixed on the upper end surface of the water tank 9, and the top of the storage box 8 is communicated with the inside of the fixed cylinder 6 through the fixed tube 7, a guide block 31 is fixed at the edge of the upper end surface of the supporting plate 3, and the cross-section of the guide block 31 is a right-angled triangle structure; when the forming cylinder 4 rotates at high speed During the process, the water pump 10 runs to transfer the liquid in the water tank 9 to the inner tube 12 through the infusion tube 11, and then the liquid enters the discharge pipe 13 and is sprayed out from the nozzle 15, spraying at equal angles on the outside of the forming cylinder 4 to cool it. When the supporting plate 3 rotates at high speed, it can drive the guide block 31 to rotate synchronously. When the guide block 31 rotates, it can contact the bottom of the discharge pipe 13 and push the discharge pipe 13 to rise. Since a rubber tube 14 is provided at the upper end of the discharge pipe 13, its position will change after being pushed. When the guide block 31 does not contact the discharge pipe 13, the rubber tube 14 can drive the discharge pipe 13 to return to its original position through its own rebound. Therefore, when the liquid is sprayed for cooling, the movement of the discharge pipe 13 can increase the liquid spraying range, and the excess liquid after spraying can flow to the bottom of the fixed cylinder 6 and flow to the storage box 8 through the fixed pipe 7 for temporary storage and cooling for subsequent recycling.

[0039] Example 2: The existing cooling mechanism does not utilize the power of high-speed rotation of the centrifuge, resulting in a waste of resources. Therefore, this embodiment adopts the following technical solutions, such as Figure 4-Figure 8As shown, the air cooling mechanism includes a fan blade 16 fixedly mounted on the output shaft of the motor 2, and a protective cover 17 is provided on the outer side of the fan blade 16, and the protective cover 17 is fixed to the support frame 1, and the protective cover 17 is connected to the outer tube 19 through the air pipe 18; the outer tube 19 is fixed to the inner top surface of the fixed cylinder 6, the outer tube 19 is an annular structure, and an exhaust pipe 20 is fixed at an equal angle below the outer tube 19, and air outlet holes 21 are reserved at equal intervals on the side of the exhaust pipe 20, and a rubber tube 14 is also provided at the disconnection point of the upper end of the exhaust pipe 20, and the bottom of the exhaust pipe 20 and the drain pipe 13 are both connected to the upper end surface of the carrier plate 3. Leave a gap; when the motor 2 is running, it can drive the fan blades 16 to rotate synchronously, and the generated gas can be transmitted to the outer tube 19 through the gas pipe 18, and then transmitted to different exhaust pipes 20 respectively, and finally discharged from the air outlet 21 and blown to the outside of the forming tube 4 to further cool it down. The cooling efficiency can be improved by spraying water and blowing air, and the fan blades 16 are driven by the power of driving the forming tube 4, so that resources can be used reasonably. At the same time, the bottom of the exhaust pipe 20 can also contact with the rotating guide block 31, so that the exhaust pipe 20 can also make a lifting movement when exhausting, thereby improving the spraying range of the gas.

[0040] Example 3: After the liquid is collected after being cooled by the existing water cooling mechanism, the temperature of the liquid is still high. The lack of a cooling mechanism causes the recovered liquid to be unable to be recycled, and the centrifuge cannot be cooled when recycled. Therefore, this embodiment adopts the following technical solutions, such as Figure 5 and Figure 9As shown, the output shaft of the motor 2 is meshed with the agitator shaft 23 through the bevel gear set 22, and the agitator shaft 23 rotates and passes through the storage box 8, and a cam 24 is fixed on the bottom of the output shaft of the motor 2; a fixed block 25 is provided on the side of the cam 24, and the fixed block 25 slides through the side of the storage box 8, and a fixed plate 26 is provided on the end of the fixed block 25 away from the cam 24, and a connecting plate 27 is fixed on the top of the fixing plate 26; the connecting plate 27 slides in contact with the inner top surface of the storage box 8, and the top of the connecting plate 27 The storage box 8 is provided with a heat dissipation vent 81, and a spring is provided between the storage box 8 and the fixed plate 26, and the lengths of the fixed plate 26 and the connecting plate 27 are both less than the width of the storage box 8, and the fixed plate 26 is slidably sleeved on the outside of the stirring shaft 23; a movable plate 28 is fixed to the bottom of the fixed plate 26, and the movable plate 28 slides in contact with the upper end surface of the water tank 9, and the interior of the movable plate 28 is uniformly reserved with fixing holes 281, and the top of the water tank 9 is uniformly provided with connecting holes 91, and the fixing holes 281 and the connecting holes 91 are staggered. The storage box 8 is connected to the water tank 9 through the fixing hole 281 and the connecting hole 91; when the motor 2 is driven, the stirring shaft 23 can also be driven to rotate by the meshing transmission of the bevel gear set 22. The stirring shaft 23 stirs the high-temperature liquid temporarily stored in the storage box 8, which can increase the speed of heat dissipation. At the same time, the motor 2 drives the cam 24 to rotate, and during the rotation process, it contacts the fixed block 25, pushing the fixed block 25 and the fixed plate 26 to move. During the movement, it drives the connecting plate 27 to move, so that the heat dissipation port 81 is open for heat dissipation. On the one hand, the air is discharged, and on the other hand, the movable plate 28 is driven to move, and after the movement, the fixing hole 281 is driven to coincide with the connecting hole 91 on the water tank 9. After the coincidence, the liquid in the storage box 8 can flow into the water tank 9 for recycling. When the fixed block 25 is not pushed, the spring resilience drives the connecting plate 27 to seal the heat dissipation port 81, and at the same time, the fixing hole 281 and the connecting hole 91 are staggered, and the liquid delivery is stopped. In this way, by intermittently delivering part of the liquid to the water tank 9, the cooling of the heated liquid can be accelerated for subsequent recycling.
