Description

Technical Field

[0001] The present invention belongs to the technical field of water mist cooling structures for casting molds, and more particularly, to a water mist cooling structure for a low-pressure casting mold of an aluminum alloy wheel. Background Art

[0002] Currently, wheels are generally produced by casting, especially low-pressure casting. The molds used for casting wheels mainly include an upper mold, a lower mold, and a side mold. After the upper mold, the lower mold, and the side mold are combined, a casting cavity for the wheel to be cast is formed. The water mist cooling structure for a low-pressure casting mold of an aluminum alloy wheel is an efficient and innovative cooling system that combines the advantages of low-pressure casting and water mist cooling, providing a more efficient and reliable solution for the manufacture of aluminum alloy wheels.

[0003] During the existing low-pressure casting process of aluminum alloy wheels, a water mist cooling system is usually set up separately. When the mold temperature rises, the system starts, sprays water mist on the mold surface. After the water mist contacts the mold surface, it quickly evaporates, taking away a large amount of heat, thereby achieving rapid cooling. This separate design increases the use cost. And during casting, the condensed water flows through the surface of the forging table through the condensate pipe, taking away a large amount of heat, causing the wheel to cool rapidly in the mold. However, the condensed water cannot be automatically replaced after each stamping, resulting in waste and increasing energy consumption. Summary of the Invention

[0014] The present invention has the following beneficial effects compared with the prior art:

[0015] 1. A water mist cooling structure for a low-pressure casting mold of an aluminum alloy wheel proposed by the present invention drives a moving plate and an upper mold to move through a driving cylinder, synchronously realizes the extrusion of water inside the air cylinder, sprays the water through a fog cooling nozzle to fully contact the surface of the mold and quickly evaporates, realizing rapid cooling. This design not only shortens the casting cycle and improves production efficiency, but also effective cooling can prevent the mold from overheating and deforming, thereby prolonging the service life of the mold. In addition, through the design of the internal circulation mechanism, the automatic circulation and replacement of condensed water during the forging process are realized, further improving the cooling efficiency and ensuring the rapid cooling of the wheel sample after forging.

[0016] 2. The internal circulation mechanism in the present invention is ingeniously designed. By driving the plate and the rod through the moving plate, and using structures such as the return spring and the pressing plate, the automatic circulation and replacement of the condensed water are realized. During the stamping test, the condensed water under the pressing plate enters above the pressing plate through the water outlet hole. At the same time, the one-way control valve is used to ensure that the condensed water cannot flow into the second condensing pipe and can only be exchanged at the water outlet hole. After the test is completed, the return spring drives the structure to reset. At the same time, the self-gravity of the condensed water and the tension of the spring are used to close the water outlet hole by the sealing cover plate, and the condensed water above is pushed into the first condensing pipe and then pushed into the cooling box for cooling. When the stamping test is carried out again, negative pressure is generated in the water tank, the one-way control valve opens, and the cooled condensed water is sucked into the water tank, realizing the automatic circulation and replacement of the condensed water. There is no need to use an electric structure, reducing energy consumption.

[0017] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the invention with reference to the accompanying drawings in the embodiments of the invention. Obviously, the described embodiments are only a part rather than all of the embodiments of the invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the invention without creative efforts shall fall within the protection scope of the invention.

[0028] In the description of the present invention, it should be understood that the terms "open hole", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0029] Please refer to Figures 1-6 As shown, the present invention is a water mist cooling structure for a low-pressure casting mold of an aluminum alloy wheel, including an operating table 1. A driving cylinder 2 is arranged above the operating table 1. The output shaft of the driving cylinder 2 penetrates through the top of the operating table 1 and is fixedly installed with a moving plate 3. The moving plate 3 is fixedly installed with an upper die 4. The moving plate 3 is fixedly installed with an air rod 5. The air rod 5 is fixedly installed with a sealing plug 6. The sealing plug 6 is slidably connected inside an air cylinder 7. One end of the air cylinder 7 is fixedly communicated with one end of a first conveying pipe 8. The other end of the first conveying pipe 8 is communicated inside a water tank 9. A first one-way valve is arranged between the first conveying pipe 8 and the water tank 9. One end of the air cylinder 7 is fixedly communicated with one end of a second conveying pipe 28. The other end of the second conveying pipe 28 is communicated with a mist cooling nozzle 10. A second one-way valve is arranged between the second conveying pipe 28 and the mist cooling nozzle. The operating table 1 is provided with an internal circulation mechanism for recycling the condensed water inside the forging table 11.

[0030] The working principle of the water mist cooling structure for a low-pressure casting mold of an aluminum alloy wheel proposed by the present invention is to start the driving cylinder 2, thereby driving the moving plate 3 and the upper die 4 to move, and then forging the wheel.

[0031] It should be noted that when the moving plate 3 moves downward, it synchronously drives the air rod 5 to move, thereby driving the sealing plug 6 to move along the inside of the air cylinder 7, and then squeezing the water inside the air cylinder 7. At this time, the first one-way valve closes and the second one-way valve opens, so that the water inside the air cylinder 7 is transmitted to the inside of the fog cooling nozzle 10 through the second delivery pipe 28, and is ejected to fully contact the surface of the mold and quickly evaporate, thus realizing rapid cooling, shortening the casting cycle, improving the production efficiency, and effective cooling can prevent the mold from overheating and deformation, thereby prolonging the service life of the mold.

[0032] Furthermore, when the moving plate 3 moves downward, it synchronously drives the internal circulation mechanism to move, thereby realizing the automatic circulation and replacement of the condensed water during the forging process, not only ensuring the rapid cooling of the wheel sample after forging, but also improving the cooling efficiency.

[0033] In one embodiment, for the above-mentioned driving cylinder 2, the driving cylinder 2 is fixedly installed on the top of the operating table 1, the air cylinder 7 is fixedly installed on the forging table 11, the forging table 11 is fixedly installed on the operating table 1, the water tank 9 is fixedly installed on the operating table 1, and one end of the fog cooling nozzle 10 is fixedly installed with a connecting rod 29, and the other end of the connecting rod 29 is fixedly installed on the operating table 1.

[0034] In one embodiment, for the above-mentioned forging table 11, a lower mold 30 is fixedly installed above the forging table 11, and the internal circulation mechanism includes a pipeline 13 opened inside the operating table 1, and a first partition 14 and a second partition 15 are fixedly installed inside the pipeline 13.

[0035] In one embodiment, for the above-mentioned first partition 14, one end of the first partition 14 is fixedly communicated with one end of the first condensing pipe 16, the other end of the first condensing pipe 16 is fixedly communicated with the cooling box 17, one end of the second condensing pipe 18 is fixedly communicated with the cooling box 17, the other end of the second condensing pipe 18 is fixedly communicated with the second partition 15, and a one-way control valve 19 is fixedly installed on the second partition 15. A water tank 31 is formed between the first partition 14 and the second partition 15.

[0036] In one embodiment, for the above-mentioned first condensing pipe 16, the first condensing pipe 16 and the second condensing pipe 18 are laid inside the pipeline 13.

[0037] In one embodiment, for the above-mentioned operating table 1, a plate 20 is slidably connected to one side of the operating table 1, a rod 21 is fixedly installed on the plate 20, the rod 21 is slidably connected inside the forging table 11, a return spring 22 is sleeved on the rod 21, one end of the return spring 22 is fixedly installed on the inner wall of the water tank 31, and the other end is fixedly installed on the connecting member 23.

[0038] In one embodiment, for the above-mentioned connecting member 23, the connecting member 23 is fixedly installed on the pressing plate 24, and the pressing plate 24 is slidably connected inside the water tank 31.

[0039] In one embodiment, for the above-mentioned pressing plate 24, the pressing plate 24 is provided with a water outlet hole 25, and a sealing cover plate 26 is slidably connected to the water outlet hole 25. One end of a spring 27 is fixedly installed on the sealing cover plate 26, and the other end of the spring 27 is fixedly installed on the connecting member 23.

[0040] The working principle of the water mist cooling structure of the low-pressure casting mold for aluminum alloy wheels proposed by the present invention is that by moving the moving plate 3 downward, the plate 20 is driven to move, thereby driving the connecting rod member 21 to move, and further causing the return spring 22 to deform and maintain a certain tension. At this time, the connecting member 23 and the pressing plate 24 continue to move. Since there is condensed water below the pressing plate 24, a resistance that hinders the downward movement of the pressing plate 24 will be generated. The generated resistance will open the sealing cover plate 26. At this time, the spring 27 deforms and maintains a certain tension, so that the condensed water below the pressing plate 24 enters above the pressing plate 24 through the water outlet hole 25. Due to the presence of the one-way control valve 19, the condensed water cannot flow into the inside of the second condensing pipe 18 and can only enter above the pressing plate 24 through the water outlet hole 25.

[0041] After the stamping test is completed, the return spring 22 is used to drive the connecting rod member 21 to reset. At this time, the condensed water above the sealing cover plate 26 generates a downward resistance on the sealing cover plate 26 by its own gravity, so that the sealing cover plate 26 covers the water outlet hole 25 and is in a closed state. The condensed water above the sealing cover plate 26 is lifted into the first condensing pipe 16, and then the tested condensed water in the first condensing pipe 16 is pushed into the cooling box 17 for cooling.

[0042] It should be noted that when the pressing plate 24 moves upward, a negative pressure state is generated in the water tank 31, thereby generating suction, so that the one-way control valve 19 is opened, and the condensed water cooled inside the cooling box 17 is sucked into the water tank 31 by using the second condensing pipe 18. When the stamping test is performed again, the above steps are repeated, so that the condensed water in the first condensing pipe 16 is automatically replaced when used next time, without the need to use an electric structure, reducing energy consumption.
