Description

Technical Field

[0001] The present invention relates to the technical field of casting processing, and specifically, it is a rapid cooling device for casting processing. Background Art

[0002] A casting is a metal formed object obtained by various casting methods, that is, the smelted liquid metal is injected into a pre-prepared mold by pouring, injection, suction or other casting methods. After cooling and subsequent processing means such as grinding, an object with a certain shape, size and performance is obtained. Castings have a very wide range of uses and have been applied to the hardware and the entire mechanical and electronic industries, etc. When processing castings, it is necessary to cool them, which plays a role in promoting solidification, controlling crystal grains, reducing defects and improving quality.

[0003] According to the "Rapid Cooling Device for Processing Aluminum Alloy Castings" provided by the Chinese patent authorization announcement number CN117483733B, the above-mentioned document can set a coolant circulation mechanism to make the coolant flow through the throttle pipe in a split flow to achieve the purpose of natural cooling. However, when the coolant flows back into the cooling tank, the cooled coolant is mixed with the high-temperature coolant again, and the natural cooling effect after the coolant is mixed is not ideal.

[0004] In common mechanized cooling devices, generally, mechanical claws are used to clamp the casting and then place it in the cooling tank. This cooling method causes the bottom of the casting not to be cooled by the coolant, resulting in a slower cooling rate at the bottom of the casting and affecting the overall cooling rate. At the same time, after the casting is placed in the cooling tank, the coolant inside is in a static state, resulting in an unsatisfactory heat absorption effect of the coolant far from the casting. Therefore, we provide a rapid cooling device for casting processing to solve the above problems. Summary of the Invention

[0005] To solve the above problems, that is, to solve the problems raised in the above background art, the present invention proposes a rapid cooling device for casting processing, including a base. A cooling tank is integrally formed on the top of the base, and a box body is integrally formed on one side of the inner cavity of the base. A pump body is installed on the outside of the through hole. The input end of the pump body extends fixedly to the bottom of the inner cavity of the box body, and the output end of the pump body is connected to a refrigerator. The output end of the refrigerator is communicated with the cooling tank through a delivery pipe; A cooling mechanism is provided outside the cooling tank. The cooling mechanism includes a gear pump. The input end of the gear pump is connected through the bottom of the side wall of the cooling tank. The output end of the gear pump is connected to a diverter. The output end of the diverter is communicated with a connecting pipe. The connecting pipe penetrates through the outer wall of the base and is connected to a heat dissipation box. The heat dissipation box is installed on one side of the top of the base corresponding to the box body. The heat dissipation box is communicated with the box body through a communicating pipe. A control valve is installed on the communicating pipe. A fan is installed in a penetrating manner on the side wall of the base corresponding to the diverter; A second motor is installed at the bottom of the cooling tank. The output shaft of the second motor is rotationally connected to the cooling tank through a sealed bearing. A connecting frame is arranged at the output end of the second motor. The connecting frame includes a connecting rod and a heat conduction plate. A plurality of the connecting rods are fixedly arranged at the output end of the second motor, and the heat conduction plate is fixedly arranged at the top of the plurality of connecting rods. A plurality of through holes are formed inside the heat conduction plate, and a plurality of flow guiding plates are annularly arranged at the top of the heat conduction plate.

[0006] Preferably, the flow divider includes a flow guiding pipe, a heat dissipation pipe and a support rod. The two flow guiding pipes are respectively communicated with the gear pump and the connecting pipe. A plurality of the heat dissipation pipes are communicated between the two flow guiding pipes. The heat dissipation pipes are arranged in a serpentine spiral shape. The support rod is arranged on the heat dissipation pipes in a serpentine shape and is fixedly connected to the inner cavity of the base.

[0007] Preferably, a gas exchange pipe is connected between the heat dissipation box and the box body. The top end of the gas exchange pipe extends to the top of the inner cavity of the heat dissipation box. A plurality of equally spaced heat conduction fins are fixedly inserted into the inner cavity of the heat dissipation box. There is a certain gap between the heat conduction fins and the bottom end of the inner cavity of the heat dissipation box. A filter screen is fixedly arranged at the top end of the heat dissipation box. An observation window is arranged on the side wall of the base corresponding to the box body.

[0008] Preferably, an installation frame is arranged on the top of the base corresponding to the cooling tank. The installation frame is fixedly connected to the base through a plurality of columns. A clamping mechanism is arranged inside the installation frame. The clamping mechanism includes an electric sliding table. The electric sliding table is fixedly arranged inside the installation frame. A sliding plate is fixedly arranged on the moving part of the electric sliding table. Cylinders are installed through both sides inside the sliding plate. The moving ends of the two cylinders are fixedly provided with a connecting plate. An installation shell is fixedly arranged at the bottom of the connecting plate. Two mutually meshing gears are rotatably arranged inside the inner cavity of the installation shell. A first motor is installed on the outer wall of the installation shell. The output end of the first motor is fixedly connected to the shaft end of one of the gears. Claw jaws are correspondingly arranged on the outer walls of the two gears. The claw jaws rotate outside the bottom opening of the installation shell.

[0009] Preferably, a sliding block is integrally formed on the outer wall of the sliding plate corresponding to the installation frame. A sliding groove is formed on the inner wall of the installation frame corresponding to the sliding block. The sliding block is slidably arranged on the inner wall of the sliding groove.

[0010] The beneficial technical effects of the present invention are as follows: Driven by the gear pump, the coolant can enter the flow divider, and several diversion pipes of the flow divider can separately transport the coolant, enabling the coolant to increase the heat exchange area with the outside air through the diversion pipes. At the same time, a fan is used to increase the air flow velocity outside the diversion pipes, enabling the coolant to achieve cooling without the intervention of a refrigerator. Moreover, the cooled coolant can continue to dissipate heat through the radiator. When the coolant in the cooling tank needs to be replaced, the coolant is transported into the cooling tank through the pump body. When the coolant in the box is emptied, the cooled coolant in the radiator is drained into the box. This setting can avoid the direct circulation of the cooled coolant, thereby increasing the cooling efficiency of the coolant.

[0011] By arranging a connecting frame in the cooling tank, the casting can be placed on the heat conducting plate, and the coolant at the bottom of the heat conducting plate can still cool the bottom of the casting, realizing the all-round cooling treatment of the casting.

[0012] By arranging a flow guiding plate in the cooling tank, the operation of the second motor can drive several flow guiding plates to rotate, and the inclined flow guiding plates can fluctuate the flow of the coolant, thereby accelerating the heat and cold exchange of the coolant with the casting and improving the cooling efficiency of the casting.

[0013] The operation of the first motor can drive two clamping jaws to clamp the casting, and under the drive of the electric sliding table, the casting can be moved to the inner cavity of the cooling tank. Starting the cylinder can lower the casting into the cooling tank, and at the same time, the casting can be taken out after cooling is completed, eliminating the need for manual handling of the casting, which is relatively convenient.

Detailed implementation manners

[0020] The preferred implementation manners of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0021] The present invention provides a rapid cooling device for casting processing, including a base 1. A cooling tank 11 is integrally formed on the top of the base 1, and a box body 12 is integrally formed on one side of the inner cavity of the base 1. A pump body 121 is installed on the outside of the box body 12. The input end of the pump body 121 extends fixedly to the bottom of the inner cavity of the box body 12, and the output end of the pump body 121 is connected to a refrigerator 122. The output end of the refrigerator 122 is communicated with the cooling tank 11 through a delivery pipe 123. This design enables the high-temperature coolant in the cooling tank 11 to be isolated from the low-temperature coolant. A temperature reduction mechanism 2 is arranged outside the cooling tank 11. The temperature reduction mechanism 2 includes a gear pump 21. The input end of the gear pump 21 is connected through the bottom of the side wall of the cooling tank 11. The output end of the gear pump 21 is connected to a diverter 22. The output end of the diverter 22 is communicated with a connecting pipe 23. The connecting pipe 23 penetrates through the outer wall of the base 1 and is connected to a heat dissipation box 24. The heat dissipation box 24 is installed on one side of the top of the base 1 corresponding to the box body 12. The heat dissipation box 24 is communicated with the box body 12 through a communicating pipe 241. A control valve 2411 is installed on the communicating pipe 241. A fan 25 is installed on the side wall of the base 1 corresponding to the diverter 22 in a penetrating manner. After the coolant enters the diverter 22, the coolant can increase the heat exchange area with the outside air through the diverter 22. At the same time, the air flow velocity outside the diversion pipe is increased by using the fan 25, so that the coolant can be cooled without the intervention of the refrigerator 122, and the cooled coolant can continue to dissipate heat through the heat dissipation box 24. This setting can prevent the directly circulating of the cooled coolant, thereby increasing the cooling efficiency of the coolant. At the bottom end of the cooling tank 11, a second motor 111 is installed. The output shaft of the second motor 111 is rotationally connected to the cooling tank 11 through a sealed bearing. A connecting frame 112 is arranged at the output end of the second motor 111. The connecting frame 112 includes a connecting rod 1121 and a heat conduction plate 1122. A plurality of connecting rods 1121 are fixedly arranged at the output end of the second motor 111, and the heat conduction plate 1122 is fixedly arranged at the top of the plurality of connecting rods 1121. A number of through holes are formed inside the heat conduction plate 1122, and a number of flow guide plates 113 are annularly arranged on the top of the heat conduction plate 1122. By arranging the connecting frame 112 in the cooling tank 11, the casting can be placed on the heat conduction plate 1122, and the coolant at the bottom of the heat conduction plate 1122 can still cool the bottom of the casting, realizing the all-round cooling treatment of the casting. At the same time, by arranging the flow guide plates 113 in the cooling tank 11, the operation of the second motor 111 can drive a number of flow guide plates 113 to rotate. The inclined flow guide plates 113 can fluctuate the flow of the coolant, thereby accelerating the heat exchange between the coolant and the casting and improving the cooling efficiency of the casting.

[0022] Specifically, the flow divider 22 includes a flow guide pipe 221, a heat dissipation pipe 222 and a support rod 223. The two flow guide pipes 221 are respectively communicated with the gear pump 21 and the connecting pipe 23. A number of heat dissipation pipes 222 are communicated between the two flow guide pipes 221. The heat dissipation pipes 222 are arranged in a serpentine shape. The support rod 223 is arranged on the serpentine heat dissipation pipes 222 and is fixedly connected to the inner cavity of the base 1. The serpentine design of the heat dissipation pipes 222 can extend the natural cooling process of the coolant, thereby ensuring the cooling efficiency of the coolant.

[0023] Specifically, an air exchange pipe 242 is connected between the heat dissipation box 24 and the box body 12. The top end of the air exchange pipe 242 extends to the top of the inner cavity of the heat dissipation box 24. A number of equally spaced heat conduction fins 243 are fixedly inserted into the inner cavity of the heat dissipation box 24. There is a certain gap between the heat conduction fins 243 and the bottom end of the inner cavity of the heat dissipation box 24. A filter screen 244 is fixedly arranged at the top end of the heat dissipation box 24. An observation window 124 is arranged on the side wall of the base 1 corresponding to the box body 12. The heat conduction fins 243 can increase the contact area with the coolant. After heat transfer, the outside of the heat conduction fins 243 further contacts the device body to realize the cooling of the coolant.

[0024] Specifically, a mounting frame 13 is provided corresponding to the cooling tank 11 at the top of the base 1. The mounting frame 13 is fixedly connected to the base 1 through a plurality of columns 131. A clamping mechanism 3 is arranged inside the mounting frame 13. The clamping mechanism 3 includes an electric slide table 31. The electric slide table 31 is fixedly arranged inside the mounting frame 13. A slide plate 32 is fixedly arranged on the moving part of the electric slide table 31. Both sides inside the slide plate 32 are installed in a penetrating manner with air cylinders 33. The moving ends of the two air cylinders 33 are fixedly provided with a connecting plate 34. The bottom of the connecting plate 34 is fixedly provided with a mounting shell 35. Two mutually meshing gears 37 are rotatably arranged in the inner cavity of the mounting shell 35. And a first motor 36 is installed on the outer wall of the mounting shell 35. The first motor 36 is a waterproof self-locking motor. The working principle mainly includes electromagnetic induction and a self-locking mechanism. The output end of the first motor 36 is fixedly connected to the shaft end of one of the gears 37. Claw jaws 38 are correspondingly arranged on the outer walls of the two gears 37. The claw jaws 38 rotate outside the bottom opening of the mounting shell 35. A slider 321 is integrally formed on the outer wall of the slide plate 32 corresponding to the mounting frame 13. A sliding groove 132 is opened on the inner wall of the mounting frame 13 corresponding to the slider 321. The slider 321 is slidably arranged on the inner wall of the sliding groove 132. By the operation of the first motor 36, the two claw jaws 38 can be driven to clamp the casting. And under the drive of the electric slide table 31, the casting can be moved to the inner cavity of the cooling tank 11. Starting the air cylinder 33 can lower the casting into the cooling tank 11. At the same time, the casting can be taken out after cooling is completed. There is no need for manual taking and placing of the casting, which is relatively convenient.

[0025] For those skilled in the art, all the electrical components and parts in this case are common standard parts or parts known to those skilled in the art. Their structures and principles can all be known by those skilled in the art through technical manuals or obtained through conventional experimental methods. As long as the models are adapted to this solution and can operate normally, all the electrical components in this case are connected to their adapted power supplies through wires. And according to the actual situation, a suitable controller is selected to meet the control requirements. For the specific connection and control sequence, the electrical connection should be completed according to the sequence of the successive operations among the electrical components in the following working principle. The detailed connection means are well-known techniques in the art, and no further description of the electrical control will be given.

[0026] Working principle: When it is necessary to cool the casting, first open the control valve 2411, inject an appropriate amount of coolant into the box body 12 from the top of the heat dissipation box 24, and at the same time inject an appropriate amount of coolant into the cooling tank 11. Then place the casting on the top of the base 1, drive the two jaws 38 to swing electrically by the first motor 36, and clamp and fix the casting. Then start the cylinder 33 to reset, drive the casting to move horizontally to the top of the cooling tank 11 by the electric slide table 31. At this time, start the cylinder 33 again to lower the casting to the top of the heat conduction fin 243. At this time, the coolant in the cooling tank 11 can cool the casting. At the same time, start the second motor 111. The work of the second motor 111 can drive the guide plate 113 to rotate, so that the coolant in the cooling tank 11 can be guided and mixed for heat exchange, accelerating the cooling rate of the casting. At the same time, since through holes are provided inside the heat conduction plate 1122 and a certain amount of coolant is stored at the bottom, the bottom end of the casting can also be quickly cooled. When the cooling is completed, take out the casting, and then start the gear pump 21 to transport the coolant in the cooling tank 11 into the shunt pipe, so that the coolant can increase the heat exchange area with the outside air through the shunt pipe. At the same time, use the fan 25 to increase the air flow rate outside the shunt pipe, so that the coolant can be cooled without the intervention of the refrigerator 122. Then the coolant enters the heat dissipation box 24 through the connecting pipe 23 for secondary natural cooling. When the coolant in the cooling tank 11 is emptied, the pump body 121 can be started, and it is determined whether to start the refrigerator 122 according to the actual situation, so that the coolant in the box body 12 can be transported into the cooling tank 11. After the coolant in the heat dissipation box 24 is naturally cooled, the control valve 2411 can be opened to discharge it into the inner cavity of the box body 12. By circulating in this way, the consumption of resources can be further reduced, and the cooling rate of the casting can be accelerated.
