Description

Technical Field

[0001] This utility model relates to the field of casting cooling technology, and in particular to a cooling device for castings with synchronous drying effect. Background Technology

[0002] Casting is one of the earliest metal heat treatment processes mastered by mankind, with a history of about 6,000 years. It is a method of pouring liquid metal into a casting cavity that conforms to the shape of the part, and then cooling and solidifying it to obtain the part or blank. The material being cast is mostly metal that was originally solid but was heated to a liquid state (e.g., copper, iron, aluminum, tin, lead, etc.), while the material of the mold can be sand, metal or even ceramic. After the casting is formed, it needs to be cooled down.

[0003] In existing technologies, castings need to be cooled after casting. However, when cooling with cooling water, the large temperature difference may affect the castings, such as causing cracks or even affecting the quality of the castings.

[0004] An existing patent (publication number: CN218517701U) discloses a cooling device for castings with a synchronous drying effect. The castings undergo initial air cooling in a casting drying box. When passing through the second air cooling zone, a cooling fan delivers cold air through ventilation pipes to various nozzles for further and deeper cooling of the castings. This gradual cooling air cooling prevents the castings from cracking due to excessive temperature difference caused by sudden application of cooling water. At the same time, by installing mesh screens at both ends and the bottom of the cooling basket, the castings can be completely immersed in the cooling water. Through a series of processes, the castings can be cooled quickly and stably, improving the efficiency of the cooling process.

[0005] To address the aforementioned issues, while existing patents offer solutions that prevent castings from cracking due to rapid cooling by allowing for gradual cooling, in practical use, the castings may tilt or fail to fully enter the sluice basket. Therefore, during the feeding process, they may be unable to be pushed out properly due to limiting mechanisms. Summary of the Invention

[0006] The purpose of this invention is to provide a cooling device for castings with synchronous drying effect, which can push the castings into the drying box for drying and avoid the castings from tilting or shifting, thus preventing them from being pushed into the drying box for drying, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a cooling device for castings with synchronous drying effect, comprising a cooling box, a cooling water tank fixedly installed at one end of the cooling box, and a drying box fixedly installed at the other end of the cooling water tank, a guide plate embedded in the outer wall of the cooling box facing the cooling water tank, and a pushing mechanism provided inside the cooling water tank;

[0008] The pushing mechanism includes a motor, which is embedded in the outer wall of the cooling water tank. The power output end of the motor is connected to a worm gear. One end of the worm gear that extends out of the cooling water tank is connected to a worm wheel. A threaded rod extends out of the inside of the worm wheel, and a pushing plate is slidably connected to one end of the threaded rod that extends out of the worm wheel. A sliding plate is sleeved on the bottom end of the pushing plate. A guide frame is fixedly installed on one side of the inside of the cooling water tank.

[0009] Preferably, the pushing mechanism further includes a bearing roller, which is rotatably connected to two axially opposite surfaces of the guide frame, and a roller is rotatably connected to the bottom end of the sliding plate.

[0010] Preferably, the threaded rod is threadedly connected to the push plate, and the push plate and the cooling water tank form a sliding structure.

[0011] Preferably, the roller is in close contact with the cooling water tank, and a sliding structure is formed between the cooling water tank and the roller.

[0012] Preferably, a cleaning mechanism is provided on one side of the guide frame. The cleaning mechanism includes a limiting plate, which is fixedly installed on the top of the guide frame. A vertical cleaning roller is rotatably connected to the opposite surfaces of the two limiting plates.

[0013] Preferably, the cleaning mechanism further includes a mounting frame, which is embedded inside the drying oven, and a transverse cleaning roller is rotatably connected inside the mounting frame. A damping spring is embedded at the top of the mounting frame, and a connecting frame is fixed to one end of the damping spring that passes through the mounting frame.

[0014] Preferably, the connecting frame has a U-shaped structure, and the connecting frame forms an elastic structure with the mounting frame through a damping spring.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Through the cooperation of motor, worm gear, worm wheel, threaded rod, push plate, sliding plate, guide frame, bearing roller and drum, the castings can be pushed into the drying box for drying, and the castings can be prevented from tilting or shifting, which would prevent them from being pushed into the drying box for drying.

[0017] 2. By using a limiting plate, vertical cleaning roller, mounting frame, horizontal cleaning roller, damping spring, and connecting frame, external moisture can be wiped off before the castings enter the drying oven, preventing marks and traces from appearing after drying and requiring secondary cleaning.

[0025] 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.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 2A cooling device for castings with simultaneous drying effect includes a cooling box 1, a cooling water tank 2 fixedly installed at one end of the cooling box 1, and a drying box 3 fixedly installed at the other end of the cooling water tank 2. A guide plate 4 is embedded in the outer wall of the cooling box 1 facing the cooling water tank 2. A pushing mechanism 5 is provided inside the cooling water tank 2. The pushing mechanism 5 includes a motor 501, which is embedded in the outer wall of the cooling water tank 2. A worm gear 502 is connected to the power output end of the motor 501. A worm wheel 503 is connected to one end of the worm gear 502 that extends out of the cooling water tank 2. A threaded rod 504 extends out of the inside of the worm wheel 503. A pusher plate 505 is slidably connected to one end of the worm gear 503. A sliding plate 506 is sleeved on the bottom end of the pusher plate 505. A guide frame 507 is fixedly installed on one side of the inside of the cooling water tank 2. The pusher mechanism 5 also includes a bearing roller 508. The bearing roller 508 is rotatably connected to the two axially opposite surfaces of the guide frame 507. A roller 509 is rotatably connected to the bottom end of the sliding plate 506. A threaded rod 504 is threadedly connected to the pusher plate 505. A sliding structure is formed between the pusher plate 505 and the cooling water tank 2. The roller 509 is tightly fitted with the cooling water tank 2. A sliding structure is formed between the cooling water tank 2 and the roller 509.

[0028] By adopting the above technical solution, the casting is first initially cooled in the cooling box 1 and then conveyed by the conveying equipment. It is then guided by the guide plate 4 to fall into the cooling water box 2 for deep cooling. After cooling, the motor 501 drives the worm gear 502, which in turn drives the worm wheel 503 to rotate the threaded rod 504. This causes the push plate 505 to drive the sliding plate 506, which slides stably along the cooling water box 2 via the roller 509. The push plate 505 and the guide plate 4 are on the same vertical line to prevent the casting from shifting and failing to enter fully, which would affect the feeding. The cooperation of the bearing roller 508 of the guide frame 507 improves the smoothness of the casting's movement and allows water to drip back into the cooling water box 2, making it easier for the casting to enter the drying box 3 for drying. When pushing the casting upward, the sliding plate 506 slides along the push plate 505 and retracts.

[0029] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, a cleaning mechanism 6 is provided on one side of the guide frame 507. The cleaning mechanism 6 includes a limiting plate 601, which is fixedly installed on the top of the guide frame 507. A vertical cleaning roller 602 is rotatably connected to the opposite surfaces of the two limiting plates 601. The cleaning mechanism 6 also includes a mounting frame 603, which is embedded inside the drying box 3. A horizontal cleaning roller 604 is rotatably connected inside the mounting frame 603. A damping spring 605 is embedded at the top of the mounting frame 603. A connecting frame 606 is fixed to one end of the damping spring 605 that passes through the mounting frame 603. The connecting frame 606 has a U-shaped structure. The connecting frame 606 and the mounting frame 603 form an elastic structure through the damping spring 605.

[0030] By adopting the above technical solution, the limiting plate 601 prevents the casting from shifting and enters the drying chamber 3. At the same time, the vertical cleaning roller 602 initially removes moisture from both sides of the casting. After entering the drying chamber 3, the horizontal cleaning roller 604 inside the mounting frame 603 removes moisture again. The connecting frame 606 is elastically pushed by the damping spring 605, so that the upper horizontal cleaning roller 604 elastically presses the casting. Under the push of the sliding plate 506, the moisture can be fully removed, avoiding the need for secondary cleaning after drying.

[0031] Working principle: After initial cooling by the cooling fan in cooling box 1, the casting is pushed by the conveying equipment to guide plate 4 and then falls into cooling water tank 2 for deep cooling. Subsequently, motor 501 drives the threaded rod 504 via worm gear 502 and worm wheel 503, which in turn drives the pushing plate 505. This causes the sliding plate 506 to slide along the cooling water tank 2 and guide frame 507 against the casting. The bearing roller 508 and roller 509 prevent excessive friction during movement. The casting moves upwards during the pushing process. 506 slides along the push plate 505 to avoid being limited, and finally enters the drying box 3 under the limit of the limit plate 601 and is dried by the drying fan. The limit plate 601 wipes the water droplets on both sides through the vertical cleaning roller 602 connected by rotation. At the same time, the top and bottom are wiped by the two horizontal cleaning rollers 604 inside the mounting frame 603. The connecting frame 606 is elastically pushed by the damping spring 605, which drives the horizontal cleaning roller 604 above to elastically resist and press the casting, and can be fully wiped.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
