DETAILED DESCRIPTION

[0025] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0026] In the description of this specification, the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or unit referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0027] like Figure 1 to Figure 7 As shown, a device for accelerating the cooling of a casting includes a box body 1 and a circulation component 2 arranged on the box body 1. The box body 1 is a metal box with a hollow interior. Cooling water for cooling the casting is injected into the box body 1. The metal box body 1 can better dissipate heat to the outside, thereby improving the cooling effect of the casting in disguise.

[0028] refer to Figure 1 to Figure 3 As shown, the liquid delivery pipe 23 of the circulation component 2 is connected to the liquid inlet hole 11 at the bottom of the box body 1, and the circulation component 2 is provided with a liquid extraction pipe 22 connected to the liquid delivery pipe 23, and the liquid extraction pipe 22 is connected to the liquid discharge hole 12 of the box body 1, and the liquid discharge hole 12 is opened on the side wall of the box body 1.

[0029] Specifically, the circulation component 2 includes a circulation pump 21 , the liquid extraction pipe 22 extracts the cooling water in the box body 1 through the circulation pump 21 , and the liquid delivery pipe 23 delivers the cooling water back into the box body 1 , so as to realize the circulation flow of the cooling water in the box body 1 .

[0030] refer to Figure 1 , Figures 4 to 7 As shown, a placement component 3 and a stirring component 4 are disposed inside the box body 1. The placement component 3, the stirring component 4, and the liquid inlet holes 11 are multiple in number and are distributed in a one-to-one correspondence.

[0031] The placement component 3 is provided with a plurality of columns 32 distributed on the periphery of the liquid inlet hole 11, and a net bag 33 is provided on the columns 32. The net bag 33 is located in the middle of the plurality of columns 32 and is fixedly connected to the columns 32. The net bag 33 is used to suspend the casting.

[0032] The columns 32 of this embodiment are vertically arranged up and down, and can also be tilted outwardly according to the actual size of the casting to increase the placement space of the casting.

[0033] The drainage hole 12 is arranged higher than the net bag 33, and when the casting is placed in the net bag 33, the height of the drainage hole 12 is also higher than the height of the casting, so that the cooling water in the box 1 can submerge the casting, so that the casting can be completely immersed in the cooling water for cooling.

[0034] The rotating plate 41 of the stirring component 4 is rotatably set on the placing component 3. Specifically, the placing component 3 is provided with a bottom plate 31 fixed on the box body 1, and the rotating plate 41 is rotatably set on the bottom plate 31. Furthermore, the bottom plate 31 and the rotating plate 41 are correspondingly provided with a groove 1 35 and a groove 2 412, and a plurality of balls 42 are arranged between the groove 1 35 and the groove 2 412. The rotating plate 41 can be better rotated on the bottom plate 31 through the balls 42. At the same time, a convex ring 34 is arranged on the bottom plate 31, and the inner diameter of the convex ring 34 is slightly larger than the outer diameter of the rotating plate 41. The rotating plate 41 is located on the inner side of the convex ring 34, that is, the rotating plate 41 is arranged close to the inner periphery of the convex ring 34.

[0035] A limiting member may also be provided on the bottom plate 31 to limit the rotating plate 41 from being separated from the bottom plate 31 during the rotation process, so that the rotation of the rotating plate 41 is more stable and reliable.

[0036] The rotating plate 41 is provided with a latching tooth 411, and the latching tooth 411 is engaged with a rotating tooth 45 for driving the rotating plate 41 to rotate. Specifically, a driving member 44 is fixed on the lower end surface of the base plate 31, and the driving member 44 can be a motor. The output shaft of the driving member 44 passes through the base plate 31 and is connected to the rotating tooth 45, and then the rotating tooth 45 rotates to drive the rotating plate 41 to rotate.

[0037] When the output shaft of the driving member 44 passes through the bottom plate 31 , a rotary seal is provided at a corresponding position of the bottom plate 31 to prevent the cooling water in the box body 1 from leaking outward.

[0038] The rotating plate 41 is provided with stirring blades 43 distributed on the outside of the columns 32. The stirring blades 43 extend obliquely upward and are distributed on the outer periphery below the net bag 33. The bottom plate 31 is provided with a conical tube 13 that is larger at the top and smaller at the bottom. The liquid inlet 11 is opened in the conical tube 13. The rotating plate 41 is annular as a whole. The columns 32 are distributed circumferentially on the bottom plate 31, and the columns 32 are distributed on the inner side of the rotating plate 41 to avoid interference of the columns 32 with the rotation of the rotating plate 41. At the same time, the annular rotating plate 41 also provides an escape space for the delivery of cooling water through the liquid inlet 11.

[0039] The liquid inlet hole 11 is arranged at the center of the tapered tube 13 and is located directly below the net bag 33. The liquid inlet hole 11 transports cooling water into the box body 1 through the liquid delivery pipe 23, and through the tapered tube 13 with a trumpet-shaped opening, the cooling water can flow to the casting placed on the net bag 33 over a larger range, so that there is always cooling water with a lower temperature around the casting for conduction and heat dissipation, thereby improving the cooling efficiency of the casting.

[0040] And through the setting of the stirring blades 43, the cooling water can be transported to the surrounding of the casting, that is, the cooling water originally diffused outward can be redirected to the surrounding of the casting through the stirring blades 43 to increase the utilization rate of the cooling water, and accelerate the flow and circulation of the cooling water around the casting, thereby accelerating the cooling speed of the casting.

[0041] At the same time, the stirring blades 43 also ensure that the cooling water around the casting has good fluidity, so as to avoid the cooling water with poor fluidity in the surrounding area of ​​the casting, which in turn leads to poor local cooling effect of the casting. That is, through the guiding and conveying cooling water setting of the stirring blades 43, the casting can be cooled more evenly and efficiently, thereby ensuring the production quality of the casting.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
