Description

Technical Field

[0001] This utility model relates to the technical field of casting spraying devices, specifically a casting cooling spraying device equipped with multi-angle spray heads. Background Technology

[0002] Casting is a metalworking process in which molten metal is poured into a hollow mold made of high-temperature resistant material, and after solidification, a product of the desired shape is obtained. In the casting production process, the cooling stage of the casting plays a crucial role in product quality. After the casting is formed, its cooling rate and uniformity need to be controlled through effective cooling methods to reduce internal stress, avoid defects such as cracks and shrinkage cavities, and ensure the mechanical properties and dimensional accuracy of the casting. Currently, the casting industry widely uses spray cooling devices to cool castings. Traditional spray systems have fixed spray head positions, typically spraying castings from only a single direction or a limited angle. This leads to significant differences in cooling rates across different parts of the casting, especially for complex-shaped castings where corners and internal cavities are prone to insufficient cooling, while exposed surfaces may experience stress concentration due to overcooling, affecting casting quality. Furthermore, the height of the spray heads in traditional systems is not flexibly adjustable. For castings of different heights and sizes, it is difficult to ensure the optimal distance between the spray head and the casting surface. Too much distance results in low cooling efficiency, while too little distance causes localized overcooling, further exacerbating the uneven cooling problem. Therefore, a casting cooling spray system with multi-angle spray heads is needed. Utility Model Content

[0015] 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.

[0016] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0017] Example 1: Based on the existing problems of uneven cooling and low cooling efficiency, the present invention provides a preferred embodiment of a casting cooling spray device with multi-angle spray heads, for example... Figure 1-4 As shown: A casting cooling spray device with multi-angle spray heads includes a support base 1, a casting cavity 11 fixedly installed on the top of the support base 1, and four sets of outer support columns 12 fixedly installed on the top of the support base 1, located outside the casting cavity 11. A cooling spray support top plate 13 is fixedly installed on the top of the outer support columns 12. A control box 2 is fixedly installed on one side of the outer wall of the support base 1 through a support arm. A protective shell 3 is fixedly installed on the outer wall of the support base 1. A casting spray assembly 4 is disposed above the support base 1 and outside the protective shell 3. The casting spray assembly 4 includes: a rotating part 41, which is disposed above the support base 1; and a spraying part 42, which is disposed outside the protective shell 3 and above the support base 1, and above and on one side of the rotating part 41.

[0018] The rotating part 41 includes: a rotating gear 411, which is located above the cooling spray support top plate 13; a rotating column 412 is installed inside the rotating gear 411 through a bearing, and the rotating column 412 is located on the top of the cooling spray support top plate 13 through a rotating ring seat; a dustproof top cover 413 is fitted on the outer wall of the top of the rotating column, and the dustproof top cover 413 is located above the rotating gear 411; a motor 414 is fixedly installed on the top of the dustproof top cover 413, and the motor 414 is fixedly connected to the rotating column 412 through a rotating shaft, thereby driving the rotating gear 411 to rotate.

[0019] The bottom of the dustproof top cover 413 is fixedly installed with support columns 415, and there are two sets in total, which are symmetrically arranged and located on both sides of the rotating gear 411. The outer wall of the support column 415 is provided with a driving pinion 416 through a bearing, and the driving pinion 416 is connected to the rotating gear 411 through gear meshing. The outer wall of the driving pinion 416 is provided with an outer ring large gear 417 through gear meshing.

[0020] A fixing ring plate 418 is fixedly installed on the outer wall of the outer ring large gear 417, and the outer circumference of the fixing ring plate 418 is provided with slots 419 at equal intervals.

[0021] Furthermore, in this embodiment, a motor 414 drives a rotating column 412 to rotate a gear 411. Through meshing with the small gears 416 on both sides, the gear 411 is synchronously driven to rotate the outer ring large gear 417. This multi-stage gear transmission design can effectively reduce speed fluctuations, allowing the fixed ring plate 418 to drive the side L spray support plate 421 to make a smooth circular motion. This ensures that the spray heads 4211 are evenly distributed around the casting cavity 11, avoiding cooling dead zones. The dustproof top cover 413 prevents dust from entering the gear meshing part. At the same time, the fixed ring plate 418 is connected to the side L spray support plate 421 through a slot 419, which facilitates quick disassembly and maintenance, enhancing the flexibility of the device.

[0022] Example 2: Based on Embodiment 1, a preferred embodiment of the casting cooling spray device with multi-angle spray heads provided by this utility model is, for example... Figure 1-4 As shown: The spraying part 42 includes: a side L spraying support plate 421, which is fixedly installed inside the slot 419, and the inner side wall of the side L spraying support plate 421 is provided with a lifting sliding hole, which extends to the top of the casting cavity 11; a water storage tank 427, which is set on one side of the outer wall of the protective shell 3, and a delivery pump is fixedly installed inside the water storage tank 427; a hydraulic telescopic rod 422 is fixedly installed on the top of the inner wall of the side L spraying support plate 421, and a moving plate 423 is fixedly installed on the bottom of the hydraulic telescopic rod 422, and the moving plate 423 is slidably connected to the lifting sliding hole.

[0023] A spray mounting base 424 is fixedly installed on the inner side wall of the movable plate 423. An annular water box 425 is fixedly installed on the top of the side L spray support plate 421. An annular water inlet hole 426 is opened on the top of the annular water box 425. A water delivery pipe 428 is connected to the connection port of the delivery pump. The water delivery pipe 428 movably passes through the top of the water storage tank 427 and extends into the interior of the annular water inlet hole 426. A control valve 429 is sleeved on the outer wall of the water delivery pipe 428.

[0024] The bottom circumference of the annular water box 425 is equidistantly connected with a water supply pipe 4210, which extends into the interior of the spray mounting base 424. The other end of the water supply pipe 4210 is connected to a spray head 4211, which is fixedly installed at the bottom of the spray mounting base 424.

[0025] Furthermore, in this embodiment, the hydraulic telescopic rod 422, which is provided on the inner wall of the side L-shaped spray support plate 421, pushes the moving plate 423 to move along the lifting sliding hole, which can precisely adjust the height of the spray mounting base 424 and the spray head 4211, so that the spray head 4211 maintains the optimal distance between the casting surface and the casting. This can achieve efficient cooling for castings of different heights and avoid insufficient cooling or overcooling due to unsuitable distance. At the same time, the annular water box 425 receives the cooling water delivered by the water storage tank 427 through the annular water inlet 426, and then distributes it evenly to each spray head 4211 through the connecting water pipes 4210 distributed around the bottom circumference, ensuring that the water volume of each spray head 4211 is stable and the spray pressure is consistent.

[0026] In operation, the first step is to start and adjust the rotation of the device. After the control box 2 issues a command, the motor 414 on top of the dustproof top cover 413 starts, driving the rotating column 412 to rotate via the rotating shaft, which in turn drives the rotating gear 411 to rotate synchronously. The rotating gear 411 meshes with the driving pinion 416 on the outer wall of the two side support columns 415, causing the pinion 416 to rotate, and simultaneously driving the outer ring gear 417 meshing with it to rotate. The fixed ring plate 418 on the outer wall of the outer ring gear 417 rotates with it, driving the side L spray support plate 421 to make a circular motion through the slot 419, so that the spray head 4211 forms a ring-shaped coverage around the casting cavity 11, laying the foundation for all-round cooling. The dustproof top cover 413 can prevent dust from entering the gear meshing parts and ensure the long-term stable operation of the rotating structure.

[0027] Furthermore, based on the height of the casting within the casting cavity 11, the hydraulic telescopic rod 422 on the top of the inner wall of the side L-shaped spray support plate 421 is activated, pushing the moving plate 423 up and down along the lifting sliding hole, thereby adjusting the height of the spray mounting base 424 and the spray head 4211 at the bottom. This process ensures that the spray head 4211 maintains the optimal distance from the casting surface, improving cooling efficiency and avoiding insufficient cooling due to excessive distance or localized overcooling due to excessive proximity. Furthermore, in the cooling spray stage, the pump inside the water tank 427 on one side of the protective shell 3 is activated, pumping cooling water through the water pipe 428 into the annular inlet 426 of the annular water box 425. The control valve 429 can adjust the water flow rate according to the cooling demand to ensure a stable water supply. The cooling water in the annular water box 425 is delivered to the spray head 4211 in the spray mounting base 424 through the connecting water pipes 4210 distributed around the bottom circumference. The spray head 4211 sprays the casting surface at high pressure. Driven by the rotating part 41, the spray head 4211 rotates and sprays simultaneously. Combined with height adjustment, this achieves 360° cooling of the casting without dead angles, evenly removing heat from the casting and accelerating its solidification. During the cooling process, control box 2 can monitor parameters such as rotation speed and spray flow rate in real time, and automatically adjust them according to the casting material and cooling progress to ensure optimal cooling effect. After cooling is completed, motor 414 and conveying pump stop working, and hydraulic telescopic rod 422 drives spray head 4211 to reset, waiting for the next cooling operation.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
