Description

Technical Field

[0001] This utility model relates to the field of wheel hub casting technology, specifically to a rapid solidification casting cooling device for aluminum alloy wheel hubs. Background Technology

[0002] A wheel hub is the rotating part of a tire, connected to the inner rim of the tire by a column. It's the metal component that supports the tire and is mounted on the axle; it's also called a rim, wheel, or tire rim. Wheel hubs come in many varieties depending on their diameter, width, forming method, and material. They are typically formed using low-pressure casting, a method that ensures good feeding, resulting in a dense casting structure. This method facilitates the casting of large, thin-walled, and complex parts without the need for risers. After casting, the mold needs to be cooled and cooled.

[0003] Publication No. CN220407066U discloses a cooling device for casting aluminum alloy wheel hubs. By installing a water inlet pipe, cooling water can be injected into the main body to cool the wheel hub inside the cavity. A small refrigeration unit fixed to the top of the starter cover can be activated, allowing cold air to be delivered into the cavity through a cold air pipe, directly and rapidly cooling the wheel hub. The simultaneous cooling of the wheel hub by the cooling water and the cold air generated by the small refrigeration unit effectively improves the cooling efficiency. However, this patent still has the following problems in practical use:

[0004] Cooling water can be injected into the main body through an inlet pipe to cool the hub inside the cavity. A small refrigeration unit fixed on the top of the start-up cover can be installed to deliver cold air into the cavity through a cold air pipe, which can directly and quickly cool the hub. The cooling water and the cold air generated by the small refrigeration unit can effectively improve the cooling efficiency of the hub inside the cavity. However, the cold air blown out by the small refrigeration unit continuously blows on the coolant, which may cause the coolant to freeze.

[0005] A rapid solidification casting cooling device for aluminum alloy wheel hubs is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a rapid solidification casting cooling device for aluminum alloy wheel hubs, to solve the problems mentioned in the background art. Currently, cooling water is injected into the main body through an inlet pipe to cool the wheel hub inside the cavity. A small refrigerator fixed on the top of the start-up cover can be used to deliver cold air into the cavity through a cold air pipe, which can directly and rapidly cool the wheel hub. By using both cooling water and the cold air generated by the small refrigerator to cool the wheel hub inside the cavity at the same time, the cooling efficiency can be effectively improved. However, the cold air blown out by the small refrigerator continuously blows onto the coolant, which may cause the coolant to freeze.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rapid solidification casting cooling device for aluminum alloy wheel hubs, comprising a base, wherein a main body is fixedly installed in the middle of the top surface of the base;

[0008] A liquid inlet pipe is connected through one side surface of the main body near the bottom, and a liquid outlet pipe is connected through the other side surface of the main body near the bottom. Valves are fixedly installed inside the liquid inlet pipe and the liquid outlet pipe, and a cover plate is fixedly installed on the top surface of the main body.

[0009] Also includes:

[0010] A drive motor is fixedly installed on one side surface of the main body near the bottom;

[0011] Among them, a rotating rod is fixedly connected to the output end of the drive motor through one side surface of the main body;

[0012] The rotating rod is rotatably connected to the main body.

[0013] Preferably, a plurality of stirring blades are connected through the surface of the rotating rod, and a perforated plate is fixedly connected to the surface of the stirring blades.

[0014] Preferably, a small refrigerator is fixedly installed in the middle of the top surface of the cover plate, and a sealing ring is fixedly installed on the bottom surface of the cover plate.

[0015] Preferably, the sealing ring is fitted and connected to the main body.

[0016] Preferably, mounting blocks are symmetrically installed on both sides of the cover plate and the main body, and a threaded rod is connected through the middle of the interior of each mounting block.

[0017] Preferably, nuts are threaded onto both sides of the threaded insert.

[0018] Preferably, the main body has symmetrically installed placement blocks inside, the top surface of the placement blocks is fitted with a support frame, and the top surface of the support frame is symmetrically installed with handles.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This rapid solidification casting cooling device for aluminum alloy wheel hubs, through the cooperation of a drive motor, rotating rod, stirring blade, and perforated plate, enables the coolant to be stirred, thereby allowing the coolant to flow within the cylinder and accelerating heat transfer between different parts of the coolant. This avoids excessively low local temperatures in the coolant, resulting in a more uniform overall temperature and reducing the possibility of freezing due to localized low temperatures. Furthermore, the cooperation between the small refrigeration unit and the coolant allows for better cooling of the aluminum alloy wheel hubs. The specific details are as follows:

[0020] 1. By incorporating a drive motor, rotating rod, stirring blades, and perforated plate, after the coolant is poured into the main body, the drive motor is activated via the control terminal. The output of the drive motor drives the rotating rod, which in turn drives the stirring blades, which in turn drive the perforated plate. This agitates the coolant inside the main body, creating flow within the cylinder and accelerating heat transfer between different parts of the coolant. This prevents localized excessively low coolant temperatures, resulting in a more uniform overall coolant temperature and reducing the likelihood of freezing due to localized low temperatures. Simultaneously, the agitation increases and evenly distributes the contact area between the coolant and the cold air, improving heat exchange efficiency. On one hand, it allows the cold air to cool the coolant more effectively, rapidly reducing the coolant temperature to a stable state close to but not below its freezing point. On the other hand, it prevents the cold air from concentrating on localized areas of the coolant, causing localized overcooling and freezing. The flow generated by the agitation also interferes with the formation and growth of ice crystals. Even in low-temperature environments, when tiny ice crystals begin to appear in the coolant, the stirring action prevents these ice crystals from accumulating and growing, thus avoiding the formation of large ice masses and maintaining the liquid state of the coolant, which allows for better cooling of the aluminum alloy wheel hub.

[0021] 2. By setting up a main body, inlet pipe, outlet pipe, valve, cover plate, small refrigerator and sealing ring, after the coolant enters the main body through the inlet pipe, the small refrigerator is started through the control terminal, so that the cold air of the small refrigerator enters the main body. Through the cooperation between the cold air and the coolant, the cooling efficiency of the aluminum alloy wheel hub can be improved. At the same time, the sealing gasket can prevent leakage.

[0022] 3. By using threaded inserts and nuts, frequent separation of the main body and cover plate is facilitated. Compared to bolts and screw holes, using threaded inserts and nuts allows for simpler and more convenient disassembly of the main body; simply unscrew the nut and pull out the threaded insert. Moreover, the threaded insert and nut can usually be replaced or repaired separately. If only the nut or threaded insert is faulty, it does not require repairing or remachining the entire screw hole as is often the case with bolts and screw holes. This makes disassembly and installation of the main body more convenient and can reduce costs to some extent. Attached Figure Description

[0029] 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.

[0030] Please see Figure 1-5 This utility model provides a technical solution: a rapid solidification casting cooling device for aluminum alloy wheel hubs, including a base 1, a main body 2 fixedly installed in the middle of the top surface of the base 1; an inlet pipe 3 is connected through one side surface of the main body 2 near the bottom, and an outlet pipe 4 is connected through the other side surface of the main body 2 near the bottom; valves 5 are fixedly installed inside the inlet pipe 3 and the outlet pipe 4; a cover plate 6 is fixedly installed on the top surface of the main body 2; it also includes: a drive motor 12 fixedly installed on one side surface of the main body 2 near the bottom; wherein, the output end of the drive motor 12 passes through one side surface of the main body 2 and is fixedly connected to a rotating rod 13; wherein, the rotating rod 13 is rotatably connected to the main body 2, such as... Figure 1-5 As shown, by setting up the cooperation between the drive motor 12, the rotating rod 13, the stirring blade 14 and the perforated plate 15, the coolant can be stirred, thereby enabling the coolant to flow in the cylinder and accelerating the heat transfer between different parts of the coolant. This can prevent the coolant from being too cold in some areas, making the overall temperature of the coolant more uniform and reducing the possibility of freezing due to local low temperature. At the same time, the cooperation between the small refrigeration unit 7 and the coolant can better cool the aluminum alloy wheel hub.

[0031] Several stirring blades 14 are connected through the surface of the rotating rod 13, and a perforated plate 15 is fixedly connected to the surface of the stirring blades 14, such as... Figure 2 , 3As shown, the drive motor 12 is started by the control terminal, which causes the output of the drive motor 12 to drive the rotation of the rotating rod 13. The rotation of the rotating rod 13 causes the stirring blade 14 to rotate, which in turn causes the perforated plate 15 to rotate. This allows the coolant inside the main body 2 to be stirred, thereby enabling the coolant to flow in the cylinder and accelerating the heat transfer between different parts of the coolant. This can prevent the local temperature of the coolant from being too low, making the overall temperature of the coolant more uniform and reducing the possibility of freezing due to local low temperature.

[0032] A small refrigeration unit 7 is fixedly installed in the middle of the top surface of the cover plate 6, and a sealing ring 8 is fixedly installed in the bottom surface of the cover plate 6. The sealing ring 8 is fitted and connected to the main body 2. Figure 3 As shown, the small refrigerator 7 is existing technology and its working principle is the same as existing technology. The model of the small refrigerator 7 is ND11-HT-188. The sealing ring 8 can prevent leakage.

[0033] Mounting blocks 9 are symmetrically installed on both sides of the cover plate 6 and the main body 2. A threaded rod 10 is threaded through the center of the mounting block 9, and nuts 11 are threadedly connected to both sides of the threaded rod 10. Figure 1 As shown, by setting the threaded rod 10 and nut 11, it is easy to frequently separate the main body 2 and the cover plate 6. At the same time, by using the threaded rod 10 and nut 11, compared with bolts and screw holes, when disassembling the main body, you only need to unscrew the nut 11 and then pull out the threaded rod 10. Relatively speaking, the operation is simpler and more convenient. Moreover, the threaded rod 10 and nut 11 can usually be replaced or repaired separately. If only the nut 11 or the threaded rod 10 has a problem, it is not necessary to repair or re-machine the entire screw hole as with bolts and screw holes. This makes the disassembly and installation of the main body more convenient and can also reduce the increase in costs to a certain extent.

[0034] Inside the main body 2, placement blocks 16 are symmetrically installed. A support frame 17 is attached to the top surface of the placement blocks 16. Handles 18 are symmetrically installed on the top surface of the support frame 17. Figure 3 , 4 As shown, this facilitates the removal of the support frame 17, thereby allowing the aluminum alloy wheel hub placed inside the support frame 17 to be retrieved.

[0035] Working principle: Before using this type of rapid solidification casting cooling device for aluminum alloy wheels, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5As shown, by first setting up a drive motor 12, a rotating rod 13, a stirring blade 14, and a perforated plate 15, after the coolant is poured into the main body 2, the drive motor 12 is started through the control terminal, so that the output end of the drive motor 12 drives the rotating rod 13 to rotate. The rotation of the rotating rod 13 drives the rotation of the stirring blade 14, and the rotation of the stirring blade 14 drives the rotation of the perforated plate 15, thereby stirring the coolant inside the main body 2. This allows the coolant to flow in the cylinder, accelerating the heat transfer between different parts of the coolant. This can prevent the local temperature of the coolant from being too low, making the overall temperature of the coolant more uniform and reducing the possibility of freezing due to local low temperature. At the same time, stirring increases and makes the contact area between the coolant and the cold air more uniform, improving the heat exchange efficiency. On the one hand, it allows the cold air to cool the coolant more effectively, so that the coolant temperature drops quickly to a stable state close to but not below its freezing point. On the other hand, it also prevents the cold air from acting on a local coolant, causing local overcooling and freezing. The flow generated by stirring can interfere with the formation and growth of ice crystals. Even in low-temperature environments, when tiny ice crystals begin to appear in the coolant, the stirring action prevents these ice crystals from accumulating and growing, thus avoiding the formation of large ice clusters and maintaining the coolant's liquid state. This allows for better cooling of the aluminum alloy wheel hubs.

[0036] Secondly, by setting up the main body 2, inlet pipe 3, outlet pipe 4, valve 5, cover plate 6, small refrigerator 7 and sealing ring 8, after the coolant enters the interior of the main body 2 through the inlet pipe 3, the small refrigerator 7 is started through the control terminal, so that the cold air of the small refrigerator 7 enters the interior of the main body 2. Through the cooperation between the cold air and the coolant, the cooling efficiency of the aluminum alloy wheel hub can be improved. At the same time, through the function of the sealing gasket, leakage can be prevented.

[0037] Finally, by setting the threaded rod 10 and nut 11, it is easy to frequently separate the main body 2 and the cover plate 6. At the same time, by using the threaded rod 10 and nut 11 compared with bolts and screw holes, when disassembling the main body, you only need to unscrew the nut 11 and then pull out the threaded rod 10. Relatively speaking, the operation is simpler and more convenient. Moreover, the threaded rod 10 and nut 11 can usually be replaced or repaired separately. If only the nut 11 or the threaded rod 10 has a problem, it is not necessary to repair or re-machine the entire screw hole as with bolts and screw holes. This makes the disassembly and installation of the main body more convenient and can also reduce the increase in costs to a certain extent.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
