Description

Technical Field

[0001] The present invention relates to a cooling device, in particular to a cooling device for producing aluminum alloy castings which is applied in the field of aluminum alloy casting processing. Background Art

[0002] Aluminum castings refer to equipment and devices made of pure aluminum or aluminum alloys by casting. Generally, a sand mold or a metal mold is used to pour the heated liquid aluminum or aluminum alloy into the mold cavity to obtain aluminum alloy blanks of various shapes. After the aluminum alloy parts are cast, their temperature is often high. In order to improve production efficiency, a cooling device is required to cool them.

[0003] There are many methods for cooling aluminum alloys. If you want to cool it down quickly, water cooling is generally used. Water cooling is to put the cast casting into cold water to quickly cool it to room temperature. For example, the specification of patent application number CN202311080201.2 discloses a rapid cooling device for the production of aluminum alloy castings, including a base, a protective shell is fixedly connected to the top of the base, a cooling box is fixedly connected to the top of the base, a water inlet is provided at the bottom of the cooling box, a water passing device is fixedly connected to the bottom of the inner surface of the water inlet, a water outlet is provided on the inner surface of the cooling box, a connecting box is fixedly connected to the outer surface of the cooling box, and a water pump is fixedly installed on the outer surface of the connecting box. The rapid cooling device for the production of aluminum alloy castings quickly cools the aluminum alloy castings by placing the aluminum alloy castings into the cooling box.

[0004] However, after the cooling of the casting cooling device disclosed above is completed, the casting needs to be manually salvaged in the coolant, resulting in poor continuity of the cooling operation and low cooling efficiency. Based on this problem, after searching, for example, the specification of the patent application number CN202211257930.6 discloses a casting cooling device for aluminum alloy production and processing, including a device body, a cooling groove is opened in the device body, the cooling groove is filled with coolant, and a cooling mechanism is arranged in the device body; the cooling mechanism includes a first rotating shaft, a second rotating shaft, and a third rotating shaft, and the first rotating shaft, the second rotating shaft, and the third rotating shaft are all connected to the device body through bearings for rotation, one end of the first rotating shaft extends through the cooling groove and has an interference fit with a rotating column, and the other end extends through the outside of the device body and has an interference fit with a pulley II. The casting cooling device has a better cooling effect on the casting, and does not require manual salvage, thereby improving the processing efficiency.

[0005] However, although the above-mentioned casting cooling equipment does not require manual salvage and removal of the cooled castings, the multiple sets of unloading mechanisms used are relatively complex in structure and require additional electrical equipment to drive, which results in high energy consumption during operation of the equipment. In addition, the failure rate of the complex unloading mechanism and electrical equipment is relatively high, which is not conducive to continuous operation. Therefore, a cooling equipment for aluminum alloy casting production is proposed to improve the above-mentioned problems. Summary of the invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the structure of the unloading mechanism is relatively complex and requires additional electrical equipment to drive, resulting in high energy consumption during operation of the equipment; the failure rate of the complex unloading mechanism and electrical equipment is relatively high, which is not conducive to continuous operation.

The driving motor can be used to drive the rotating shaft to rotate the drainage baffle, and the aluminum alloy casting can be placed into the coolant in the cooling trough by using the drainage baffle. The cooled aluminum alloy casting is then pulled out through the drainage baffle. When the discharge inclined plate corresponding to the cooled aluminum alloy casting rotates to the topmost position, the cooled aluminum alloy casting slides off the discharge inclined plate to realize automatic unloading, thereby realizing stable and continuous operation of the cooling equipment and improving processing efficiency.

[0009] As a further supplement to the present application, the horizontal plane where the lowest side of a material discharge inclined plate located at the uppermost side is located is not lower than the horizontal plane where the upper end surface of the cooling box is located, ensuring that the aluminum alloy casting can slide smoothly away from the cooling device.

[0010] As a further supplement to the present application, a protruding structure is provided on the end surface of the unloading inclined plate away from the rotating shaft to prevent the aluminum alloy casting from being adsorbed on the surface of the unloading inclined plate due to water and being unable to slide down smoothly.

[0011] As a further supplement to the present application, the raised structure includes a plurality of auxiliary unloading rollers, which are arranged parallel to each other and are rotatably installed on the unloading inclined plate at equal intervals along the length direction of the unloading inclined plate; relative to the sliding friction between the aluminum alloy casting and the unloading inclined plate, the rolling friction between the auxiliary unloading rollers and the aluminum alloy casting makes the resistance during the unloading process of the aluminum alloy casting smaller, the unloading is smoother, and the overall operation of the equipment is more stable.

[0012] As a further supplement to the present application, the unloading inclined plate is hollowed out, and a slag discharge structure is provided on the side of the unloading inclined plate close to the rotating shaft; when the unloading inclined plate corresponding to the cooled aluminum alloy casting rotates to the topmost position, the metal slag attached to the surface of the aluminum alloy casting falls to the lower side of the hollowed-out unloading inclined plate and is discharged through the slag discharge structure.

[0013] As a further supplement to the present application, the slag discharge structure includes a slag collecting inclined plate, and the slag collecting inclined plate is arranged parallel to the material unloading inclined plate.

[0016] As a further supplement to the present application, the slag collecting inclined plate is an arc-shaped plate, and the concave surface of the slag collecting inclined plate faces one side of the unloading inclined plate, and a plurality of drainage holes are arranged on the slag collecting inclined plate; the arc-shaped slag collecting inclined plate has better elastic properties and better vibration effect.

[0017] As another improvement of the present application, the inner surface of the cooling trough is equidistantly and integrally provided with a plurality of arc-shaped ribs, and the side end of the drainage baffle close to the inner surface of the cooling trough is provided with a recess matched with the arc-shaped ribs; the plurality of arc-shaped ribs provided can support the aluminum alloy casting. On the one hand, it can prevent the aluminum alloy casting from being too close to the inner surface of the cooling trough during the cooling process, which may cause uneven cooling of the close surface of the aluminum alloy casting. The aluminum alloy casting is supported by the arc-shaped ribs, which can ensure that the aluminum alloy casting is in the middle of the cooling water and cools more evenly; on the other hand, the metal slag dropped from the surface of the aluminum alloy casting can be gathered in the gap formed by two adjacent arc-shaped ribs, which is not easy to cause wear to the aluminum alloy casting during the movement of the aluminum alloy casting.

[0018] In summary, through the coordinated arrangement of the arc-shaped cooling trough and the loading and unloading mechanism including the drainage baffle and the unloading inclined plate, the driving motor can be used to drive the rotating shaft to rotate with the drainage baffle, and the aluminum alloy casting can be placed into the coolant in the cooling trough by using the drainage baffle, and then the cooled aluminum alloy casting can be pulled out by the drainage baffle, and when the unloading inclined plate corresponding to the cooled aluminum alloy casting rotates to the topmost position, the cooled aluminum alloy casting slides off the unloading inclined plate to realize automatic unloading, thereby realizing stable and continuous operation of the cooling equipment and improving processing efficiency; by arranging a protruding structure including a plurality of auxiliary unloading rollers on the end face of the unloading inclined plate away from the rotating shaft, on the one hand, it can effectively prevent the aluminum alloy casting from being adsorbed on the surface of the unloading inclined plate under the action of water and unable to slide smoothly, and on the other hand, The sliding friction between the aluminum alloy casting and the unloading inclined plate, and the rolling friction between the auxiliary unloading roller and the aluminum alloy casting make the resistance in the unloading process of the aluminum alloy casting smaller, the unloading is smoother, and the overall operation of the equipment is more stable; in addition, when the unloading inclined plate corresponding to the cooled aluminum alloy casting rotates to the topmost position, the metal slag attached to the surface of the aluminum alloy casting falls to the lower side of the hollow unloading inclined plate, and the slag collecting inclined plate at the topmost position rotates with the vibration plate along with the drainage baffle.

There are multiple unloading inclined plates 6, and a unloading inclined plate 6 is installed between two adjacent drainage baffles 4. The unloading inclined plate 6 is inclined downward toward the side away from the driving motor 5.

[0025] Based on the above description, through the coordinated arrangement of the arc-shaped cooling trough 2 and the loading and unloading mechanism including the drainage baffle 4 and the unloading inclined plate 6, the driving motor 5 can be used to drive the rotating shaft 3 to rotate with the drainage baffle 4, and the drainage baffle 4 can be used to place the aluminum alloy casting into the coolant in the cooling trough 2, and then the cooled aluminum alloy casting is pulled out through the drainage baffle 4, and when the unloading inclined plate 6 corresponding to the cooled aluminum alloy casting rotates to the topmost position, the cooled aluminum alloy casting slides off the unloading inclined plate 6 to realize automatic unloading, thereby realizing stable and continuous operation of the cooling equipment and improving processing efficiency.

[0026] Among them, Figure 2 It is shown that the horizontal plane where the lowest side of the uppermost unloading inclined plate 6 is located is not lower than the horizontal plane where the upper end surface of the cooling box 1 is located, ensuring that the aluminum alloy casting can slide smoothly away from the cooling device.

[0027] Among them, a convex structure is provided on the end surface of the side of the material cutting inclined plate 6 away from the rotating shaft 3; to prevent the aluminum alloy casting from being adsorbed on the surface of the material cutting inclined plate 6 under the action of water and unable to slide smoothly, preferably, as Figure 4 It is shown that the raised structure includes a plurality of auxiliary unloading rollers 7, which are arranged parallel to each other and are rotatably installed on the unloading inclined plate 6 at equal intervals along the length direction of the unloading inclined plate 6; compared with the sliding friction between the aluminum alloy casting and the unloading inclined plate 6, the rolling friction between the auxiliary unloading rollers 7 and the aluminum alloy casting makes the resistance in the unloading process of the aluminum alloy casting smaller, the unloading is smoother, and the overall operation of the equipment is more stable.

[0028] Among them, the unloading inclined plate 6 is hollowed out (not shown in the figure), and a slag discharge structure is provided on the side of the unloading inclined plate 6 close to the rotating shaft 3; when the unloading inclined plate 6 corresponding to the cooled aluminum alloy casting rotates to the topmost position, the metal slag attached to the surface of the aluminum alloy casting falls to the lower side of the hollowed out unloading inclined plate 6 and is discharged through the slag discharge structure.

[0029] Specifically, Figure 5 and Figure 6It is shown that the slag discharge structure includes a slag collecting inclined plate 8, and the slag collecting inclined plate 8 is arranged parallel to the unloading inclined plate 6, a slag guiding hole 14 is arranged on the side end of the cooling box 1 away from the driving motor 5, and a slag collecting box 15 connected with the slag guiding hole 14 is fixed on the outer wall of the cooling box 1; the metal slag falls on the slag collecting inclined plate 8, and slides along the downward inclined side of the slag collecting inclined plate 8, and slides into the slag collecting box 15 through the slag guiding hole 14 for unified collection.

[0030] Further, such as Figure 7 As shown, a vibration plate 9 is provided on the side of the slag collecting inclined plate 8 away from the unloading inclined plate 6, a plurality of transmission rods 10 are evenly fixed between the vibration plate 9 and the slag collecting inclined plate 8, the vibration plate 9 does not contact the drainage partition plate 4, and a vibration structure is provided between the vibration plate 9 and the cooling box 1. Specifically, the vibration structure includes a movable block 11, a fixed ring 12 and a fixed block 13. The movable block 11 is fixed to the end surface of the vibration plate 9 away from the slag collecting inclined plate 8, the fixed ring 12 is fixed to the inner wall of the cooling box 1, and the output end of the driving motor 5 passes through the fixed ring 12, as shown in FIG. Figure 6 and Figure 8 As shown, a plurality of fixed and shifting blocks 13 are provided, and the plurality of fixed and shifting blocks 13 are fixed on the arc-shaped outer wall of the fixing ring 12 at equal intervals and contact the fixing ring 12 .

[0031] As the slag collecting inclined plate 8 at the top rotates with the vibrating plate 9 along with the drainage baffle 4, the movable block 11 on the vibrating plate 9 collides with multiple fixed blocks 13 on the surface of the fixed ring 12, causing the vibrating plate 9 to vibrate. The vibrating plate 9 then transmits the vibration to the slag collecting inclined plate 8 better through multiple transmission rods 10, causing the slag collecting inclined plate 8 to vibrate with a larger amplitude, allowing the metal slag on the upper surface of the slag collecting inclined plate 8 to roll down smoothly.

[0032] Among them, Figure 7 It is shown that the slag collecting inclined plate 8 is an arc-shaped plate, and the concave surface of the slag collecting inclined plate 8 faces one side of the unloading inclined plate 6, and a plurality of drainage holes are arranged on the slag collecting inclined plate 8; the arc-shaped slag collecting inclined plate 8 has better elasticity and better vibration effect.

When the unloading inclined plate 6 corresponding to the cooled aluminum alloy casting rotates to the topmost position, the cooled aluminum alloy casting slides off the unloading inclined plate 6 to realize automatic unloading, thereby realizing the stable and continuous operation of the cooling equipment and improving the processing efficiency. By providing a convex structure including a plurality of auxiliary unloading rollers 7 on the end surface of the unloading inclined plate 6 away from the rotating shaft 3, on the one hand, it can effectively prevent the aluminum alloy casting from being adsorbed on the surface of the unloading inclined plate 6 under the action of water and unable to slide smoothly.

By arranging a slag discharge structure and a vibration structure on the side of the feed inclined plate 6 close to the rotating shaft 3, when the feed inclined plate 6 corresponding to the cooled aluminum alloy casting rotates to the topmost position, the metal slag attached to the surface of the aluminum alloy casting falls to the lower side of the hollow feed inclined plate 6. In the process of the slag collecting inclined plate 8 at the topmost position carrying the vibration plate 9 with the drainage baffle 4, the movable block 11 on the vibration plate 9 and the multiple fixed blocks 13 on the surface of the fixed ring 12 collide with each other, causing the vibration plate 9 to vibrate.

On the one hand, it can prevent the aluminum alloy casting from being too close to the inner surface of the cooling groove 2 during the cooling process, which may cause uneven cooling of the close surface of the aluminum alloy casting. The aluminum alloy casting is supported by the arcuate ribs 16, which can ensure that the aluminum alloy casting is in the middle of the cooling water and the cooling is more uniform; on the other hand, the metal slag dropped from the surface of the aluminum alloy casting can be gathered in the gap formed by two adjacent arcuate ribs 16, and it is not easy to cause wear to the aluminum alloy casting during the movement of the aluminum alloy casting.

[0035] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection.
