Description

Technical Field

[0001] The present application relates to the technical field of casting production, and in particular to a casting sand cooling device. Background Art

[0002] Fused ceramsite sand, also known as gem sand, foundry sand, and bauxite ceramsite sand, is made of high-quality bauxite as raw material through calcination, electric melting, granulation, screening and other ceramsite sand processes. It is suitable for various metal castings. The cavity of the casting is formed inside the foundry sand, and then the metal solution is poured into the cavity. After cooling, the casting can be obtained.

[0003] The foundry sand needs to be cooled after use. The Chinese patent "CN216828503U" discloses "a boiling cooling bed", which can cool the molding sand and blow the molding sand to the sand outlet at the same time. The molding sand falling on the head end of the boiling plate is sprayed by a spray mechanism to improve the cooling effect of the molding sand. At the same time, the spray head atomizes and sprays the water in the spray pipe, so that the spray water is evenly sprayed on the molding sand to improve the cooling effect. However, the large-scale use of spray cooling will not only cause a waste of water resources, but also form a large amount of water vapor when the temperature difference is too large, which is also a big problem for the collection of water vapor.

[0043] Embodiment

[0044] After the foundry sand is used, it needs to be cooled. The Chinese patent "CN216828503U" discloses "a fluidized cooling bed", which can cool the molding sand and blow the molding sand towards the sand outlet at the same time. The spraying mechanism is used to spray the molding sand falling at the head end of the fluidized plate to improve the cooling effect of the molding sand. At the same time, the spray head atomizes and sprays the water in the spray pipe, so that the sprayed water is evenly sprayed on the molding sand to improve the cooling effect; however, a large amount of spraying for cooling not only causes waste of water resources, but also forms a large amount of water vapor in the case of too large a temperature difference, which is also a big problem for the collection of water vapor. To solve the above technical problems, the following technical solutions are provided in this embodiment:

[0045] Specifically, please refer to Figures 1-5, in this embodiment, he provides a casting sand cooling device, including a box body main body 10, a cooling component 20 slidably arranged in the box body main body 10, and a power component for driving the cooling component 20 to move;

When the casting sand passes through the heat conduction pipe 22, its heat is conducted to the heat conduction pipe 22, and then the heat is taken away by the flowing water, thereby realizing the cooling of the casting sand; there are multiple cooling components 20, that is, the casting sand will pass through the cooling of multiple cooling components 20 during the process from the feed port 11 to the discharge port 12, so as to effectively improve the cooling efficiency; in addition, this solution further uses the cooperation of the reciprocating drive component and the guide plate 40 to drive the outer frame 21 to move horizontally back and forth, which can avoid excessive accumulation of casting sand affecting its falling, thus ensuring the smoothness of the casting sand during the cooling process.

[0054] Specifically, the guide groove 41 is arranged in a straight line, and its straight extension direction is set at an angle with the horizontal direction;

[0055] In the above solution, the guide groove 41 is arranged obliquely, that is, when the guide plate 40 moves in the vertical direction, the guide post 23 under the limiting action will be affected by the guide groove 41 to realize horizontal movement at the same time.

In this way, when the rotary drive member 31 drives the rotary cam 33 to rotate, the rotary motion can be converted into the vertical reciprocating motion of the guide plate 40, and then the horizontal reciprocating motion of the outer frame 21 is realized through the cooperation of the guide groove 41, the limiting groove and the guide post 23.

The limiting block 421 cooperates with the sliding groove 42 to limit the sliding of the guide plate 40;

[0060] Furthermore, please refer toFigure 5 , the cross-section of the limiting block 421 is T-shaped;

[0061] In the above solution, the limiting block 421 and the sliding groove 42 cooperate to limit the guiding plate 40, so that the limiting plate can realize stable reciprocating movement in the vertical direction.

[0062] Specifically, the heat conduction tube 22 is a metal tube;

[0063] In the above solution, the heat conduction tube 22 is made of a metal tube, which can have good heat conduction performance, and at the same time has sufficient strength to extend the service life.

[0064] Specifically, please refer to Figure 3 , a metal mesh 26 is provided in the outer frame 21, and the metal mesh 26 is arranged above the heat conduction tube 22 and is adapted to abut against the heat conduction tube 22;

[0065] In the above solution, a metal mesh 26 is further provided on the outer frame 21 of this solution, which can realize the separation of the casting sand. Cooperating with the horizontal shaking of the outer frame 21, the caking problem of the casting sand can be effectively alleviated, and then the contact area between the casting sand and the metal mesh 26 or the heat conduction tube 22 can be increased, and the cooling efficiency of the casting sand can be increased.

[0066] Specifically, a material guiding plate 14 is provided at one end of the box body main body 10 close to the discharge port 12. A guiding slope is formed on the material guiding plate 14, and the material guiding plate 14 is used to guide the material to the discharge port 12;

[0067] In the above solution, the material guiding plate 14 can guide the material to be discharged from the discharge port 12, thereby improving the smoothness of the blanking.

[0068] Specifically, support feet 13 are provided at the bottom of the box body main body 10;

[0069] In the above solution, the support feet 13 are used to support the box body main body 10, so that the bottom of the box body main body 10 is suspended, and there is enough space below the blanking port to collect the casting sand.

[0070] Specifically, a first bus bar 50 and the second bus bar (not shown in the figure) are provided on the outer wall of the box body main body 10. The first bus bar 50 is communicated with the water inlet pipes 24 of a plurality of cooling assemblies 20, and the second bus bar is communicated with the water outlet pipes 25 of a plurality of cooling assemblies 20;
