Description

Technical Field

[0001] This utility model relates to the field of casting cooling devices, and more particularly to a cooling device for cast workpieces and a casting processing system. Background Technology

[0002] Casting is the process of pouring molten metal into a mold cavity that conforms to the shape and size of the part, allowing it to cool and solidify to obtain a blank or part. During casting, after the casting is formed, it needs to be cooled. However, existing methods of cooling castings result in a large amount of waste sand adhering to the surface. Cooling is primarily achieved through water spraying, which carries away the waste sand. This waste sand tends to accumulate in the lower tank, adhering to the tank and clogging the water holes. This necessitates temporary shutdowns during cooling to clean the water holes, leading to low cooling efficiency. Furthermore, because the waste sand disperses in various corners of the tank during cooling, it is difficult to clean afterward, resulting in high maintenance costs. Utility Model Content

[0036] like Figure 1-6 A cooling device for cast workpieces includes: a cooling water tank 1, a shelf 2, and a cooling water outlet pipe 3;

[0037] The cooling water tank 1 is provided with a cooling inner cavity 11 and a sand collection cavity 12; the bottom wall of the cooling inner cavity 11 is inclined downward and extends inclinedly to the sand collection cavity 12, and the cooling water tank 1 is provided with a drain outlet 13 at the sand collection cavity 12; the shelf 2 is installed in the cooling inner cavity 11; the shelf 2 is provided with multiple horizontal shelves 21, which are spaced apart and form a hollow opening 22; the output end of the cooling water outlet pipe 3 is located in the cooling inner cavity 11 and above the horizontal shelves 21.

[0038] This solution provides a cooling device for casting workpieces, which has a cooling inner cavity 11 and a sand collection cavity 12 in a cooling water tank 1, and a shelf 2 in the cooling inner cavity 11. The shelf 2 can hold the casting workpieces, and the cooling water tank 1 can spray water onto the casting workpieces to achieve rapid cooling. The sand collection cavity 12 collects the waste sand washed away from the casting workpieces. It has the effects of cooling, rinsing and sand collection on the cast workpieces after molding, which solves the problems of low cooling efficiency and high maintenance cost of large-scale cooling of casting workpieces.

[0039] Specifically, inside the cooling water tank 1, there are a cooling inner cavity 11 and a sand collecting cavity 12. The cooling inner cavity 11 is equipped with a storage rack 2. The storage rack 2 has multiple horizontal storage plates 21. The casting workpiece can be directly placed on one or more of the horizontal storage plates 21, and the horizontal storage plates 21 lift the casting workpiece upward. At the same time, the horizontal storage plates 21 are separated by hollow openings 22 from each other. Therefore, the water sprayed from above the horizontal storage plates 21 by the cooling water outlet pipe 3 can reach the casting workpiece. The water takes away the heat on the surface of the casting workpiece and falls through the hollow openings 22 to the bottom wall of the cooling inner cavity 11. The bottom wall of the cooling inner cavity 11 is inclined, and the water flow will flow downward along the inclined bottom wall. The lower position of the cooling inner cavity 11 is connected to the sand collecting cavity 12, so the water will fall into the sand collecting cavity 12. When the water passes through the casting workpiece, it will take away the waste sand on the surface of the casting workpiece, and the waste sand will fall to the bottom wall of the cooling inner cavity 11 under the action of gravity. Since the cooling water tank 1 is provided with a drain port 13 at the sand collecting cavity 12, the overall water flow is transmitted towards the drain port 13, and the waste sand will gather in the sand collecting cavity 12, thus achieving the effect of recovering the waste sand. Further, since the water in the cooling water tank 1 will flow out through the drain port 13, the water used in large-scale cooling is discharged in a timely manner, improving the heat exchange effect, and enabling a large amount of waste sand to gather in the sand collecting cavity 12 to reduce the subsequent maintenance cost. In this way, the water output by the cooling water outlet pipe 3 not only has a cooling function for the casting workpiece, but also can wash away the waste sand on the surface, and can also control the water flow direction by using the relative position of the drain port 13 in the sand collecting cavity 12 to gather the waste sand in the sand collecting cavity 12, solving the problems of low cooling efficiency of the casting workpiece and high maintenance cost for large-scale cooling.

[0040] Optimally, the cooling water outlet pipe 3 has an annular structure 30, and multiple water outlet openings 31 are provided on the side wall of the cooling water outlet pipe 3. Some of the horizontal storage plates 21 pass horizontally below the annular structure 30.

[0041] The cooling water outlet pipe 3 of this solution can be designed into an annular structure 30 as needed. The annular structure 30 can be a completely closed "square" shape or a semi-closed "U" shape with a ring opening. Based on the fact that multiple water outlet openings 31 are provided on the side wall of the cooling water outlet pipe 3, the annular structure 30 can increase the water outlet range. The casting workpiece is arranged on the horizontal storage plate 21 below the annular structure 30, and the surrounding water outlet openings 31 can spray water on the casting workpiece from multiple angles, improving the cooling effect.

[0042] Part or the whole of the cooling water outlet pipe 3 can be directly or indirectly arranged in the cooling inner cavity 11 in a known manner and located above the horizontal storage plate 21, such as ordinary placement, screw fixation, welding fixation, snap fixation, etc.

[0043] Optimally, the storage rack 2 is provided with a vertical support plate 23 below the annular structure 30;

[0044] The upper end of the vertical support plate 23 is provided with a plate groove 231, and the cooling water outlet pipe 3 is placed downward in the plate groove 231.

[0045] In one embodiment of this solution, it is not necessary to directly lock the cooling water outlet pipe 3 into the cooling inner cavity 11. To accommodate casting workpieces of different shapes, sizes, and dimensions on the horizontal placement plate 21, it can be replaced with ring structures 30 of different pipe lengths, inner ring sizes, and shapes as needed. Therefore, this solution optimizes the structure of the vertical support plate 23. The upper end of the vertical support plate 23 is provided with a plate groove 231, and the cooling water outlet pipe 3 only needs to be placed downwards into the plate groove 231 for fixation. The inner wall of the plate groove 231 limits the cooling water outlet pipe 3, preventing it from detaching.

[0046] Alternatively, one segment of the annular structure 30 may pass through the sidewall of the cooling cavity 11 and extend out of the outside of the cooling water tank 1.

[0047] The annular structure 30 of this design can simultaneously spray water onto a casting workpiece through multiple cooling water outlet pipes 3. Water only needs to be added to one end of one of the cooling water outlet pipes 3 of the annular structure 30. One end of the cooling water outlet pipe 3 passes through the side wall of the cooling inner cavity 11, which facilitates direct external water addition. Water can flow through the multiple cooling water outlet pipes 3 of the annular structure 30 and be sprayed out from the outlet 31. One of the cooling water outlet pipes 3 of the annular structure 30 can be connected to the inlet water pipe 51 using an adapter pipe.

[0048] Alternatively, the drain outlet 13 can be located above the sand collection chamber 12.

[0049] The sand collecting chamber 12 is mainly used to collect waste sand. In this design, a drain outlet 13 is preferably set above the sand collecting chamber 12, and a height difference is formed between the drain outlet 13 and the opening of the sand collecting chamber 12. The water flow can carry the waste sand towards the sand collecting chamber 12, and the waste sand will fall into the sand collecting chamber 12 under the action of gravity. During the mass cooling process of the casting workpiece, a large amount of water can be discharged from the drain outlet 13 above the sand collecting chamber 12, and the waste sand falls into the sand collecting chamber 12 without blocking the drain outlet 13 above.

[0050] Optimally, it also includes: sand collection mesh 4;

[0051] The sand collecting mesh 4 is detachably installed in the sand collecting cavity 12.

[0052] This solution facilitates the post-processing of waste sand. During the cooling process, the sand collecting mesh 4 can be installed in the sand collecting chamber 12. When the sand collecting chamber 12 is about to be filled with waste sand, the waste sand mainly accumulates in the sand collecting mesh 4. At this time, the sand collecting mesh 4 can be periodically removed from the sand collecting chamber 12, the waste sand cleaned, and then reinstalled. In this way, the waste sand will not directly accumulate on the inner wall of the sand collecting chamber 12, reducing the cleaning difficulty and meeting the requirements of large-scale cooling.

[0053] Optimally, multiple horizontal storage plates 21 are crisscrossed to form storage stations 211 with storage functions; multiple cooling water outlet pipes 3 are connected in sequence and surround to form a ring structure 30, and the multiple ring structures 30 are distributed along the length of the cooling inner cavity 11; each ring structure 30 is exposed in the storage station 211.

[0054] The scheme has multiple annular structures 30, which are distributed along the length of the cooling cavity 11. Each annular structure 30 exposes a placement station 211, and each placement station 211 can be used to place the casting workpiece. Therefore, the annular structures 30 at different positions can independently spray water to cool the casting workpiece at their respective positions. The cooling process of the casting workpiece can be carried out independently, which improves the flexibility of cooling.

[0055] Optimally, it also includes: water inlet component 5;

[0056] The water inlet assembly 5 includes: a water inlet branch pipe 51, a water inlet main pipe 52, a water inlet valve 53, and a pump body 54;

[0057] The input end of the annular structure 30 is connected to the output end of one of the water inlet pipes 51, and the input ends of multiple water inlet pipes 51 are connected to the same main water inlet pipe 52; each water inlet pipe 51 is equipped with the water inlet valve 53; the pump body 54 is installed on the main water inlet pipe 52.

[0058] This solution uses a single water inlet pipe 51 connected to a single ring structure 30, while the input ends of multiple water inlet pipes 51 are connected to the same main water inlet pipe 52. Therefore, water can be drawn in using the pump body 54 of the main water inlet pipe 52 and output to the ring structure 30 through different water inlet pipes 51. Each water inlet pipe 51 is equipped with a water inlet valve 53, and the water spraying effect of each storage station 211 can be controlled individually by controlling the water inlet valve 53.

[0059] A casting processing system includes a robot and a cooling device for a casting workpiece as described above.

[0060] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
