Description

Technical Field

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

[0002] Casting processing is the process of pouring liquid metal into a casting cavity with a shape and size that is suitable for the part, waiting for it to cool and solidify to obtain a blank or part. In the casting processing process, after the casting is formed, the molded casting needs to be cooled. The existing cooling device for castings usually uses a spray mechanism to spray and cool the casting, but the cooling effect is not good for the bottom end surface of the casting, and if the nozzle on the spray mechanism is not cleaned for a long time and becomes clogged, it will also cause poor cooling effect on the casting.

[0003] According to patent publication number CN217595881 U, a device for rapid cooling of castings for casting is disclosed, which relates to the technical field of cooling castings, including a cooling box, slots are respectively provided on both sides of the cooling box, and a transmission mesh belt is provided through two slots in the cooling box, and a cooling component is provided outside the top of the transmission mesh belt in the cooling box, and connecting columns are fixedly provided on both sides of the top of the cooling component, and the top of the connecting column is fixedly connected to the cooling box, and a cleaning component is provided inside the cooling component, and a water storage tank is provided at the bottom of the cooling box, and a filter screen is provided at the top of the water storage tank. The design structure of the utility model is reasonable. When the water pump works, the water in the water storage tank is pumped into the fixed frame, and then sprayed out through the nozzle. By setting the transmission mesh belt into a grid shape, the nozzle at the bottom can spray water to the bottom end face of the casting, so that the two end faces of the casting can be cooled at the same time, thereby improving the cooling effect of the casting. The following problems exist in the prior art:

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 As shown, the utility model provides a casting rapid cooling device for casting, including a box body 1, a water tank 2 and a conveying assembly 8, the lower surface of the box body 1 is fixedly connected to the upper surface of the water tank 2, a water outlet pipe 3 is fixedly connected to the lower right side of the water tank 2, a feed port 4 that passes through inside and outside is opened at the lower right side of the box body 1, a conveying device 5 is arranged inside the feed port 4, two fixed plates 6 are movably connected to the front and rear sides of the right side of the conveying device 5, the backs of the two fixed plates 6 are fixedly connected to the right side of the box body 1, and two heat exhaust pipes 7 are fixedly connected to the left and right sides of the upper surface of the box body 1;

[0027] The casting is placed on top through the arrangement of the conveying assembly 8 and the conveying device 5, so that the casting moves to the inside of the box body 1 through the feed port 4. The arrangement of the water outlet pipe 3 facilitates the discharge of water in the water tank 2, and a wooden plug is provided in the water outlet pipe 3 to prevent water from flowing out. When the water in the water tank 2 needs to be replaced, the wooden plug is pulled out, and the water inside it is discharged through the water outlet pipe 3.

[0028] like Figure 2As shown, the left side of the outer surface of the conveying device 5 extends to the interior of the box body 1, and two plates 21 are movably connected to the front and rear of the left side of the conveying device 5. The lower ends of the two plates 21 are fixedly connected to the lower surface of the inner wall of the water tank 2. The outer surface of the heat exhaust pipe 7 extends to the interior of the box body 1 from below. A cooling component 11 is fixedly connected to the upper right side of the interior of the box body 1. The outer surface of the heat exhaust pipe 7 runs through the interior of the cooling component 11. Two driving motors 12 are fixedly connected to the front and rear of the left side of the upper surface of the inner wall of the box body 1. The output shafts of the two driving motors 12 are fixedly connected to two fixing rods 13, and the two fixing Two threaded rods 23 are fixedly connected to the lower end of the rod 13, and the outer surfaces of the two threaded rods 23 are threadedly connected with a convex placement component 22, the bottom of the convex placement component 22 overlaps with the lower surface of the inner wall of the water tank 2, and the protruding part of the convex placement component 22 overlaps with the opposite surfaces of the two plates 21, and a discharge port 14 that passes through inside and outside is opened below the left inner wall of the box body 1, and a baffle 15 is fixedly connected to the inner wall side of the left side of the cooling component 11 near the discharge port 14, and a water inlet pipe 16 is fixedly connected to the front of the left side of the water tank 2, and the right end of the water inlet pipe 16 is in a horizontal position with the inner wall of the water tank 2;

[0029] When it is needed, the casting is placed on the conveying assembly 8 and moved to the conveying device 5 for transmission and movement, and the casting is initially cooled by the structural setting inside the cooling assembly 11 to prevent cracks caused by direct contact with water. After the conveying device 5 moves the casting to the appropriate position, it falls on the convex placement assembly 22, and the setting of the drive motor 12 is started to drive the fixed rod 13 and the threaded rod 23 to rotate clockwise, so that the convex placement assembly 22 moves downward. Due to the action of the water inside the water tank 2, the water submerges the casting when the convex placement assembly 22 moves downward, thereby completing the rapid cooling of the casting. After cooling, the fixed rod 13 and the threaded rod 23 are rotated counterclockwise by the setting of the drive motor 12, so that the convex placement assembly 22 moves upward, and the position of the convex placement assembly 22 is limited by the setting of the baffle 15, and then the operator takes out the cooled casting through the discharge port 14 to complete the operation.

[0030] like Figure 3 As shown, the convex placement component 22 includes a convex platform 221, and a plurality of through openings 222 connected to each other in a rectangular array are opened on the inner wall upper surface of the convex platform 221, three rollers 223 are movably connected to the right side of the upper surface of the convex platform 221 in the vertical direction, and a rubber plate 224 is fixedly connected to the left side of the upper surface of the convex platform 221 in the vertical direction;

[0031] The provision of the opening 222 facilitates the entry of water when the convex placement component 22 moves downward, and the provision of the roller 223 facilitates the convex placement component 22 to move upward after cooling and contact the baffle 15 to limit the position, while the roller 223 rolls on the surface of the conveying device 5 to prevent direct contact therewith, and the rubber plate 224 has a buffering and protective effect after contacting the baffle 15.

[0032] like Figure 4 - Figure 5 As shown, the cooling component 11 includes a cooling box 111, the upper surface of the cooling component 11 is provided with three ventilation holes 112 communicating with the inside and outside, the lower surface of the inner wall of the cooling box 111 is provided with a square opening 114 communicating with the inside and outside, three fan assemblies 113 are fixedly connected to the upper surface of the inner wall of the cooling box 111, and the three fan assemblies 113 include three motors and three fan blades, two cooling boxes 115 are fixedly connected to the left and right sides of the lower surface of the inner wall of the cooling box 111, and two heating boxes 116 are fixedly connected to the upper surfaces of the two cooling boxes 115, The interior of the heat box 116 is fixedly connected to the outer surface of the heat exhaust pipe 7, and a plurality of condensing tubes 117 are fixedly connected above the opposite surfaces of the two cooling boxes 115. Two heating copper plates 1161 are fixedly connected to the middle of the inner walls of the two heating boxes 116. A ventilation port 1162 connected up and down is opened in the middle of the upper surfaces of the two heating copper plates 1161. A plurality of semiconductor cooling sheets 1163 are fixedly connected to the lower surfaces of the inner walls of the two heating boxes 116 in a rectangular array, and the lower ends of the plurality of semiconductor cooling sheets 1163 extend to the interior of the cooling box 115.

[0033] The heating copper plate 1161 is heated to provide heat inside the heating box 116. The semiconductor cooling sheet 1163 is provided to convert the internal heat into cold air and cool the water inside the cooling box 115. The cooled water enters the interior due to the action of the condenser 117. The fan assembly 113 is provided to blow air so that the cold air on the surface of the condenser 117 is blown through the square opening 114 to perform preliminary cooling treatment on the casting. When there is a lot of heat in the heating box 116, it is discharged outside through the heat exhaust pipe 7. The ventilation port 1162 is provided to facilitate the heat generated by the semiconductor cooling sheet 1163 itself during operation to pass through the ventilation port 1162 and enter the interior of the heat exhaust pipe 7 for discharge.

[0034] The working principle of the casting rapid cooling device for castings is described in detail below.

[0035] The casting is transported by the setting of the conveying device 5, and the copper plate 1161 and the semiconductor refrigeration plate 1163 are heated by the structure inside the cooling component 11 to cool the cooling box 115, so that the cooled water passes through the setting of the fan component 113 in the condenser 117 to put cold air on the casting, thereby performing a preliminary cooling treatment on the casting. When the conveying device 5 moves the casting to the appropriate position, it falls on the convex placement component 22, and the setting of the driving motor 12 is started to drive the fixing rod 13 and the threaded rod 23, so that the convex placement component 22 moves downward. Due to the action of the water inside the water tank 2, the water floods the casting when the convex placement component 22 moves downward, thereby completing the rapid cooling of the casting.

[0036] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
