Description

Technical Field

[0001] The utility model relates to the technical field of casting production, in particular to a cooling device used for the production of cast iron parts. Background Art

[0002] Casting cooling is a crucial step in the casting process. It involves cooling high-temperature metal castings to room temperature. Usually, the casting cooling process is more complicated and requires precise control to ensure the quality and performance of the castings. The correct cooling method and speed are crucial to avoiding casting defects, improving production efficiency and saving energy.

[0003] For example, in the patent document with application number 202320265762.9, a cooling device for processing cast iron parts is disclosed, and it is specifically disclosed that the cooling effect of the cast iron parts is improved by placing the cast iron parts on a loading plate and combining cold air and spray cooling.

[0004] In the above technical solution, when the cast iron part is placed on the loading plate, the bottom of the cast iron part and the bottom of the loading plate are in close contact, and the high-temperature cast iron part transfers part of the heat to the loading plate. At this time, the heat distribution of the cast iron part is initially uneven. When cooling is combined with cooling by cold air and spraying, the upper surface of the cast iron part is directly cooled. However, for the bottom of the cast iron part, the cold air and spraying water cannot act on its contact surface, and the cooling effect on the bottom of the cast iron part is not good, resulting in further uneven heat distribution of the cast iron part. For this cast iron part, its internal stress is uneven, affecting the quality of the finished product of the cast iron part. Utility Model Content

[0005] The technical problem solved by the utility model is to solve the problem in the prior art that when the cast iron part is placed on a loading plate, the contact area between the loading plate and the cast iron part is large, resulting in poor cooling effect on the bottom of the cast iron part and uneven cooling effect on the whole cast iron part.

[0006] The utility model can be implemented through the following technical scheme: a cooling device for the production of cast iron parts includes a loading base, which is installed on a lifting device through a lifting mechanism, the loading base is frame-shaped, and a loading platform for separately erecting cast iron parts of different shapes can be detachably installed on the loading base, and the middle position of the loading platform is hollow.

[0007] A further technical improvement of the utility model is that a mounting base is fixed on the inner side of the loading base, and a matching base for mounting on the mounting base is arranged on the side of the loading platform.

[0008] A further technical improvement of the utility model is that: the matching base and the mounting base are respectively provided with bolt mounting holes for realizing the connection between the matching base and the mounting base through bolts.

[0009] A further technical improvement of the utility model is that the hoisting mechanism includes a fixed base, the fixed base is fixedly installed on the side of the loading platform, the fixed base is fixed with a top rod by connecting the support rod, and the top rod is provided with a hoisting ring for cooperating with the hoisting equipment.

[0010] A further technical improvement of the utility model is that it also includes a spraying transverse plate for cooling the cast iron parts with cold air and coolant, the spraying transverse plate can move laterally, and the spraying transverse plate passes through the connecting support rod.

[0011] A further technical improvement of the utility model is that the spraying horizontal plate is fixedly installed on the output end of the movable telescopic rod through a movable push plate.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The present application adopts a frame-shaped loading base, so that loading platforms of different shapes can be installed in the middle of the frame-shaped loading base, for example, a frame-shaped loading platform or a circular loading platform can be installed, so that the loading platform can be suitable for installing cast iron parts of different shapes. Furthermore, since the middle position of the loading platform is hollow, the cast iron part can be mounted on the loading platform according to its shape. When the cast iron part is cooled by cold air or coolant, the cold air and coolant can contact various positions of the cast iron part respectively. In this process, the contact area between the cast iron part and the loading platform can be reduced, and the possibility of uneven cooling of the cast iron part as a whole can be reduced, thereby ensuring the quality of the finished cast iron part.

[0014] 2. The present application sets a fixed base on the side of the loading base and uses a connecting support rod to install the top rod. When the lifting equipment is hoisted on the lifting ring, the gravity of the cast iron part itself and the gravity of the loading base and the loading platform are utilized. At the same time, under the action of the connecting support rod, the center of gravity height of the cast iron part is lowered. When the lifting equipment drives the cast iron part to move, the stability of the cast iron part is guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0022] See also Figure 1-4 As shown, a cooling device for producing cast iron parts comprises a carrier base 1. In the present application, the carrier base 1 is frame-shaped, and a carrier platform is detachably mounted inside the carrier base 1. Usually, the carrier platform is arranged based on the shapes of different cast iron parts. For example, a frame-shaped carrier platform 5 or a circular carrier platform 6 is detachably arranged on the carrier base 1, wherein the frame-shaped carrier platform 5 and the circular carrier platform 6 are respectively arranged based on the shapes of different cast iron parts. The cast iron parts are selectively mounted on carrier platforms of different shapes according to their shapes. For example, when the cast iron part is square, First, a frame-shaped loading platform 5 of appropriate size is installed in the hollow position of the loading base 1, and then the cast iron parts are mounted on the frame-shaped loading platform 5. Under the action of gravity, the cast iron parts are pressed on the frame-shaped loading platform 5 to reduce the movement of the cast iron parts during the cooling process. Cold air or coolant can be sprayed on the top and bottom of the cast iron parts to cool them down. At the same time, the top and bottom of the cast iron parts are cooled down to reduce the contact area between the cast iron parts and the frame-shaped loading platform 5, and the generation of irregular stress is reduced, thereby ensuring the quality of the generated cast iron parts.

[0023] In order to achieve detachable installation of the loading platform, a mounting base 2 is fixed on the loading base 1, and a mating base 4 is arranged on the side of the loading platform. The mating base 4 is mounted on the mounting base 2. In order to further achieve the stability of the loading platform and the loading base 1, bolt mounting holes 3 are provided on the mounting base 2 and the mating base 4, which are used to limit the relative position of the mounting base 2 and the mating base 4 through threaded connection of bolts and nuts.

[0024] For conventional cast iron parts, after the initial cooling of the cast iron parts, in order to ensure the cooling rate, the cast iron parts usually need to be placed in a cooling pool and fully contacted with cooling water to quickly cool the cast iron parts. However, when the conventional loading plate drives the cast iron parts to land in the cooling pool, the cooling effect of the contact surface between the conventional loading plate and the cast iron parts is still lower than the non-contact surface between the loading plate and the cast iron parts. However, in the present application, by adopting the function of the frame-shaped loading platform 5 and the circular loading platform 6, the cast iron parts can be quickly and fully cooled by reducing the non-contact surface, thereby ensuring its cooling effect.

[0025] The present application replaces the cylinder controlling the height of the loading plate in the prior art with a method for controlling the height of the loading platform by hoisting, so that the hoisting of the loading platform facilitates the transfer of the loading platform, that is, the loading platform is installed on the hoisting equipment to achieve rapid transfer of the loading platform.

[0026] That is, a fixed base 7 is fixed on the side of the loading base 1, a connecting support rod 8 is fixedly installed on the fixed base 7, a top rod 9 is installed on the end of the connecting support rod 8, a lifting base 10 is fixed on the top rod 9, and a lifting ring 11 for lifting the loading base 1 is installed on the lifting base 10. In the present application, the lifting ring 11 and the loading base 1 are separated by utilizing the connecting support rod 8, so as to place large cast iron parts, so that the cast iron parts together with the loading base 1 are separated from the lifting ring 11, and the center of gravity of the loading base 1 and the cast iron parts are highly biased to the position near the loading base 1, thereby preliminarily ensuring the stability of the cast iron parts when they are moved, and realizing the stable transfer of the cast iron parts.

[0027] Since the cast iron part is located between the top rod 9 and the loading base 1, when the cast iron part is cooled by the cold air or coolant at its top or bottom by hoisting, the cold air or coolant at the top is directly sprayed onto the top rod 9, causing uneven distribution of coolant or uneven distribution of cold air at the position of the cast iron part corresponding to the top rod 9.

[0028] Therefore, the above technical problem is solved in the present application by horizontally arranging a spraying horizontal plate 12, that is, a plurality of groups of nozzles 15 are arranged on the spraying horizontal plate 12, and the nozzles 15 are divided into jet heads and water spray heads according to their functions, which are used to realize cooling treatment of the cast iron parts. At the same time, a movable push plate 13 is fixed on the spraying horizontal plate 12, and the movable push plate 13 is installed at the output end of the movable telescopic rod 14. By starting the movable telescopic rod 14, the lateral movement of the movable push plate 13 is controlled, so that the spraying horizontal plate 12 can enter between the two groups of connecting support rods 8, and then the cast iron parts are cooled by the cooling process. For example, the jet head is first started, and the jet head is used to realize continuous spraying of cold air, and the cold air is directly sprayed onto the upper surface of the cast iron part, and the lower surface of the cast iron part also has a corresponding jet head to perform jet cooling on its lower surface, and then the water spray head is activated at the same time, and the water spray head is used to cool the upper and lower surfaces of the cast iron part at the same time.

[0029] When the utility model is in use, the cast iron piece is selected and mounted on loading platforms of different shapes according to its shape. For example, when the cast iron piece is square, firstly, a frame-shaped loading platform 5 of an appropriate size is installed on the hollow position of the loading base 1. At this time, the matching base 4 is mounted on the mounting base 2. The matching base 4 and the mounting base 2 are relatively fixed by the matching action of bolts and nuts. Then, the cast iron piece is mounted on the frame-shaped loading platform 5. Under the action of the gravity of the cast iron piece, it is pressed on the frame-shaped loading platform 5. Then, the output end of the lifting device is lifted on the lifting ring 11 by the lifting device. The loading base 1 is driven to move horizontally by the movement of the lifting device. The loading base 1 is only moved to the cooling position. The movable telescopic rod 14 is started to control the movable push plate 1 3 moves horizontally, so that the spraying horizontal plate 12 can enter between the two groups of connecting support rods 8, and then the casting is cooled by the cooling process, for example, the jet end is first started, and the jet end is used to realize the continuous spraying of cold air, and the cold air is directly sprayed onto the upper surface of the casting, and the lower surface of the casting also has a corresponding jet end to spray and cool its lower surface, and then the water spray end is simultaneously activated, and the water spray end is used to cool the upper and lower surfaces of the casting at the same time; after the casting is sufficiently cooled, the spraying horizontal plate 12 or the spraying bottom plate located at the bottom of the carrier base 1 is moved out, and the height of the carrier base 1 is controlled by the lifting equipment, so that the carrier base 1 falls into the cooling water, and the casting is sufficiently cooled by the cooling water.

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention.
