Description

Technical Field

[0001] The utility model relates to the technical field of casting processing, in particular to a casting temperature reduction cooling device. Background Art

[0002] Castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and then cooled and polished to obtain objects with a certain shape, size and performance.

[0003] For example, the Chinese patent with authorization announcement number CN219648679U discloses a casting cooling device, including a cooling box, threaded rods are movably connected to the middle part of both sides of the cooling box, motors are installed at the lower ends of the threaded rods, limit plates are installed at the upper ends of the threaded rods, movable rings are threadedly connected to the outer sides of the threaded rods, mounting blocks are fixedly connected to the inner sides of the movable rings, limiting frames are installed on the inner sides of the mounting blocks, wire mesh is arranged on the inner sides of the limiting frames, and the limiting frames are installed on the inner sides of the mounting blocks.

[0004] The above-mentioned casting cooling device has the advantage of being able to clean the castings while cooling; however, the above-mentioned casting cooling device still has some disadvantages, such as: currently, large-scale casting processing is carried out continuously, and the casting processing time interval cannot be determined. Most casting cooling devices need to place a large number of castings to be cooled in a cooling box, cool them at the same time, and end the cooling at the same time. In this process, the generated castings cannot be cooled in time, and need to wait until the cooling of the previous batch of castings is completed before cooling can be carried out, resulting in a long cooling time, which reduces the cooling efficiency of the castings. At the same time, there is more moisture on the surface of the casting after cooling, and it cannot be cleaned in time, which makes the casting easy to rust and affects the quality. Utility Model Content

[0005] In view of the problems mentioned in the background technology, the purpose of the utility model is to provide a casting cooling device to solve the problems mentioned in the background technology.

[0015] By adopting the above technical solution, when the telescopic end of the servo electric cylinder moves, it drives the strip plate fixed on the Z-shaped plate to move vertically, so that the spraying height of the cooling nozzle on the spray bracket can be adjusted.

[0016] Preferably, a water pump is fixed on one side of the water tank, the water inlet of the water pump is connected to the water filter, and the water outlet is connected to the plurality of cooling nozzles through a pipeline.

[0017] By adopting the above technical solution, the water inlet of the water pump is connected to the water filter, so that the sucked water can be filtered and processed to improve the water quality so as to be transported to the cooling nozzle for spraying.

[0018] Preferably, an air pump is fixed to one side of the spray hood, and an air outlet of the air pump is connected to the air hood.

[0019] By adopting the above technical solution, when the wind force with relatively high pressure generated by the wind pump is transmitted to the wind hood, the moisture attached to the surface of the casting can be removed, thereby reducing the residual moisture.

[0020] Preferably, a valve is fixed at the bottom of the drain pipe.

[0021] By adopting the above technical solution, the water source can be replaced and impurities can be discharged when the valve fixed at the bottom of the drain pipe is opened.

[0022] Preferably, a barrier curtain is provided on one side of the feed chute, and the barrier curtain is fixed on one side of the spray hood.

[0023] By adopting the above technical solution, the water mist emission can be reduced through the curtain, and the moisture scattered in the surrounding air and on the ground can be reduced.

[0024] In summary, the utility model mainly has the following beneficial effects:

[0025] First, in the casting cooling device, the two rotating shafts installed on the frame facilitate the installation of the conveyor chain, so that the castings can be placed on the conveyor chain for transportation in time after processing. The water tank arranged under the frame provides a water source for the multiple cooling nozzles installed on the spray bracket, so that the multiple cooling nozzles spray water on the surface of the casting to quickly cool it down. When the conveyor chain is running, the castings can be placed directly and cooled in time without waiting for the same batch to be processed and cooled at the same time, which can greatly save time and improve the cooling efficiency of the castings.

[0026] Second, in the casting cooling device, the spray hood can reduce the diffusion of water to avoid making the ground slippery. Impurities can be sunk through the drainage pipe to ensure that there are fewer water impurities inside the connecting pipe. Impurities in the water can be filtered out through the water filter to improve the quality of cooling water and reduce pipeline blockage. The wind hood fixed on the bent plate can be used to air-dry the casting after cooling to remove a large amount of attached water, reduce rust stains on subsequent castings, and improve quality.
