Description

Technical Field

[0001] This utility model relates to the field of steel casting technology, and in particular to a high-efficiency cooling device for casting large steel castings. Background Technology

[0002] In the casting process of large steel castings, chills are often used to quench the castings to optimize the solidification sequence. In order to improve cooling efficiency, a water-cooling device with cooling channels inside the chill has emerged in the prior art, which continuously removes heat through circulating coolant.

[0003] Chinese patent application number 202320778600.5 discloses a high-efficiency cooling device for casting large steel castings, comprising: a cooling box with a mounting hole on its top surface and a fixing frame fixedly connected inside the mounting hole; a placement plate fixedly connected inside the fixing frame, and a plurality of liquid inlet holes on one side of the cooling box; and a heat-conducting component disposed on the top surface of the fixing frame for conducting heat from the steel casting.

[0004] The water cooling device usually has a fixed external structure, and the matching relationship between its heat absorption components and the chill mold is fixed. This means that a set of devices can only be used for the production of castings of specific shapes and sizes. When the dimensions of the casting chills are different, the original fixed water cooling device cannot be effectively matched, resulting in poor versatility and difficulty in flexible application in a multi-variety, small-batch production environment. Therefore, this utility model proposes a high-efficiency cooling device for casting large steel castings to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the problem that water cooling devices typically have a fixed external structure, and the matching relationship between their heat-absorbing components and chill molds is fixed. This results in a single device being applicable only to the production of castings of specific shapes and sizes. When the dimensions of the chill castings are different, the original fixed water cooling device cannot be effectively fitted to them, resulting in poor versatility and difficulty in flexible application in multi-variety, small-batch production environments. Therefore, this invention proposes a high-efficiency cooling device for casting large steel castings.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-efficiency cooling device for casting large steel castings includes a base, a support frame fixedly mounted on the top of the base, an opening on the top of the support frame, and an electric push rod fixedly mounted inside the opening. The high-efficiency cooling device for casting large steel castings also includes:

[0008] An adjustment mechanism is located at the bottom of the electric push rod and is used to facilitate the cooling of different chilled iron molds.

[0009] A cooling mechanism is located on top of the support frame and is used to cool the chilled iron mold.

[0010] As a preferred embodiment of this utility model, the adjustment mechanism includes: a movable box, a motor, a first bevel gear, a second bevel gear, a lead screw, a threaded sleeve, and a water-cooling head;

[0011] The output shaft of the electric push rod is fixedly connected to the moving box. The top of the inner cavity of the moving box is fixedly connected to the first motor. The output shaft of the first motor is fixedly connected to the first bevel gear. All four corners of the first bevel gear mesh with the second bevel gear. The end of the second bevel gear away from the first bevel gear is fixedly connected to the lead screw. There are four lead screws. The end of the lead screw away from the second bevel gear is rotatably connected to the inner cavity of the moving box. The surface of the lead screw is movably connected to the inner cavity of the threaded sleeve. There are four threaded sleeves. The bottom of the threaded sleeve passes through the moving box and is fixedly connected to the water cooling head. There are four water cooling heads.

[0012] As a preferred embodiment of the present invention, the cooling mechanism includes: a water storage tank, a water pump, a delivery pipe, a first return water pipe, a branch pipe, a guide pipe, and a second return water pipe;

[0013] The water storage tank is fixedly installed on the top of the support frame. The rear side of the water storage tank is connected to the water pump, and the rear side of the water pump is connected to the delivery pipe. The end of the delivery pipe away from the water pump is connected to the base. The left side of the rear side of the base is connected to the first return water pipe. The end of the first return water pipe away from the base is connected to the water storage tank. The front side of the delivery pipe is connected to the distribution pipe. The distribution pipe is connected to one end of the water cooling head. One end of the water cooling head, located at the bottom of the distribution pipe, is connected to the guide pipe. One end of the guide pipe is connected to the second return water pipe. The end of the second return water pipe away from the guide pipe is connected to the water storage tank.

[0014] As a preferred embodiment of this utility model, the front and rear sides of both sides of the inner cavity of the support frame are provided with sliding grooves, and the front and rear sides of both sides of the movable box are provided with sliding rails, with the sliding grooves cooperating with the sliding rails.

[0015] As a preferred embodiment of this utility model, cooling fans are connected to both sides of the support frame.

[0016] As a preferred embodiment of this utility model, openings are provided at the four corners of the bottom of the movable box, and the openings are matched with threaded sleeves.

[0017] As a preferred embodiment of this utility model, the end of the lead screw away from the second bevel tooth is rotatably connected to the inner cavity of the moving box via a rotating shaft.

[0018] Beneficial effects:

[0019] 1. By setting an electric push rod, the moving box can be raised and lowered. By setting a motor to drive the first bevel gear to rotate, the first bevel gear drives the four second bevel gears to rotate synchronously, the second bevel gears drive the lead screw to rotate, and the lead screw drives the threaded sleeve and water cooling head to move horizontally, thereby realizing the adjustment of the spacing of the four water cooling heads, so that the water cooling heads can fit tightly against the surface of chills of different sizes, effectively improving the adaptability of the device to molds of different specifications.

[0020] 2. A water pump is installed to pump the coolant in the water tank into the distribution pipe through the delivery pipe. The distribution pipe distributes the coolant to each water head. The coolant flows in the water head and absorbs the heat transferred by the chill. After absorbing heat, the coolant is collected through the guide pipe to the second return pipe and flows back to the water tank. At the same time, the cooling fan cools the chill. The delivery pipe also delivers the coolant to the inner cavity of the base to further absorb heat energy. Then it flows back to the water tank from the first return pipe, accelerating heat dissipation and enabling the coolant to maintain its cooling capacity, thus achieving continuous and efficient cooling of the chill.

[0021] In this invention, the spacing between the water cooling heads is adjusted to accommodate chills of different sizes, and the combination of circulating liquid cooling and air cooling provides continuous and efficient cooling of the chills, overcoming the shortcomings of fixed cooling devices in terms of poor versatility.

[0031] The cooling mechanism is located on top of the support frame 2 and is used to cool the chilled iron mold.

[0032] The adjustment mechanism includes: a movable box 4, a motor 5, a first bevel gear 6, a second bevel gear 7, a lead screw 8, a threaded sleeve 9, and a water cooling head 10;

[0033] The output shaft of the electric push rod 3 is fixedly connected to the movable box 4. The top of the inner cavity of the movable box 4 is fixedly connected to the first motor 5. The output shaft of the first motor 5 is fixedly connected to the first bevel gear 6. All four corners of the first bevel gear 6 mesh with the second bevel gear 7. The end of the second bevel gear 7 away from the first bevel gear 6 is fixedly connected to the lead screw 8. There are four lead screws 8. The end of the lead screw 8 away from the second bevel gear 7 is rotatably connected to the inner cavity of the movable box 4. The surface of the lead screw 8 is movably connected to the inner cavity of the threaded sleeve 9. There are four threaded sleeves 9. The bottom of the threaded sleeve 9 is movably connected. Box 4 is fixedly connected to water cooling head 10. There are four water cooling heads 10. The moving box 4 can be raised and lowered by setting electric push rod 3. The first bevel tooth 6 is driven to rotate by setting motor 5. The first bevel tooth 6 drives the four second bevel teeth 7 to rotate synchronously. The second bevel teeth 7 drive the lead screw 8 to rotate. The lead screw 8 drives the threaded sleeve 9 and the water cooling head 10 to move horizontally, thereby realizing the adjustment of the spacing of the four water cooling heads 10. This allows the water cooling head 10 to fit tightly against the surface of chills of different sizes, effectively improving the adaptability of the device to molds of different specifications.

[0034] The cooling mechanism includes: a water storage tank 11, a water pump 12, a delivery pipe 13, a first return water pipe 14, a branch pipe 15, a guide pipe 16, and a second return water pipe 17;

[0035] The water storage tank 11 is fixedly installed on the top of the support frame 2. The rear side of the water storage tank 11 is connected to the water pump 12, and the rear side of the water pump 12 is connected to the delivery pipe 13. The end of the delivery pipe 13 away from the water pump 12 is connected to the base 1. The left side of the rear side of the base 1 is connected to the first return water pipe 14. The end of the first return water pipe 14 away from the base 1 is connected to the water storage tank 11. The front side of the delivery pipe 13 is connected to the branch pipe 15. The branch pipe 15 is connected to one end of the water cooling head 10. One end of the water cooling head 10, located at the bottom of the branch pipe 15, is connected to the guide pipe 16. One end of the guide pipe 16 is connected to the second return water pipe 17. The end of the second return water pipe 17 away from the guide pipe 16 is connected to the water storage tank 11. The tank 11 is connected, and the coolant in the water storage tank 11 is pumped into the distribution pipe 15 through the delivery pipe 13 by the water pump 12. The distribution pipe 15 distributes the coolant to each water cooling head 10. The coolant flows in the water cooling head 10 and absorbs the heat transferred by the chill. After absorbing heat, the coolant is collected through the guide pipe 16 to the second return water pipe 17 and flows back to the water storage tank 11. At the same time, the cooling fan 18 cools the chill. Meanwhile, the delivery pipe 13 also delivers the coolant to the inner cavity of the base 1 to further absorb heat energy. Then it flows back to the water storage tank 11 from the first return water pipe 14 to accelerate heat dissipation, so that the coolant can maintain its cooling capacity and achieve continuous and efficient cooling of the chill.

[0036] The sliding groove and the sliding rail are used to ensure that the lifting process of the moving box 4 is smooth and to prevent the water cooling head 10 from shifting. The front and rear sides of both sides of the inner cavity of the support frame 2 are provided with sliding grooves, and the front and rear sides of both sides of the moving box 4 are provided with sliding rails. The sliding groove and the sliding rail cooperate with each other.

[0037] The cooling fan 18 can accelerate the heat dissipation efficiency of the cool air. Both sides of the support frame 2 are connected to the cooling fan 18.

[0038] To provide guidance and space for the movement of the threaded sleeve 9 and the water cooling head 10, openings are provided at the four corners of the bottom of the movable box 4, and the openings are matched with the threaded sleeve 9.

[0039] To enhance the operational stability of the lead screw 8 and ensure transmission accuracy, the end of the lead screw 8 furthest from the second bevel tooth 7 is rotatably connected to the inner cavity of the moving box 4 via a rotating shaft.

[0040] It should be noted that all electrical equipment used in this application is powered by an external power source. The specific models of electric actuators 3, motors 5, and water pumps 12 used can be selected by those skilled in the art. Furthermore, the electric actuators 3, motors 5, and water pumps 12 mentioned above are all existing technologies and will not be described in detail in this solution.

[0041] The working principle of this utility model is as follows: During use, the operator starts the electric push rod 3, which pushes the moving box 4 downwards to a suitable height. Then, the motor 5 is started. The output shaft of the motor 5 drives the first bevel gear 6 to rotate. The first bevel gear 6 drives the four meshing second bevel gears 7 to rotate synchronously. The second bevel gears 7 drive the lead screw 8 to rotate within the moving box 4. The rotational motion of the lead screw 8 is converted into linear motion of the threaded sleeve 9 along the axis of the lead screw 8, thereby driving the four water cooling heads 10 to move towards the center or outwards until the end faces of the water cooling heads 10 are in close contact with the side surfaces of the chills placed on the base 1, completing the positioning and clamping. At this time, the water pump 12 and the cooling fan 1 are started. 8. The water pump 12 draws out the coolant from the water tank 11 and delivers it to the distribution pipe 15 and the base 1 through the delivery pipe 13. The distribution pipe 15 evenly distributes the coolant to the four water cooling heads 10. When the coolant flows through the water cooling head 10, it absorbs a large amount of heat transferred from the chill. After absorbing heat and heating up, the coolant is collected through the guide pipe 16 and flows back to the water tank 11 through the second return water pipe 17. At the same time, the cooling fan 18 continuously blows air onto the chill and its surroundings to accelerate the dissipation of heat from the surface of the chill into the air, thus completing the cooling of the coolant. The cooled coolant can be drawn out again by the water pump 12 for recycling, thereby achieving continuous, uniform and efficient circulating cooling of the chill.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
