[0024] In the above specific embodiment, the supporting platform 4 is slidably installed on the workbench 1, and the casting is transferred to between the two groups of clamping mechanisms 8 through the supporting platform 4. When the surface of the casting is cleaned, the casting is clamped and fixed through the cooperation of the two groups of clamping mechanisms 8, and the casting is rotated while being clamped. The spray gun assembly 9 sprays water onto the surface of the casting to wash away the waste sand on the surface of the casting, thereby eliminating the need to manually move the casting, effectively improving the cleaning effect of the casting, and the water after cleaning will flow into the water tank 5 for recycling, reducing the waste of water resources.

[0025] In this embodiment, the supporting platform 4 is slidably mounted on the guide rod 6, and the guide rod 6 is fixedly mounted on the workbench 1. One end of the guide rod 6 is located at the end of the workbench 1 away from the hood 2, and a first hydraulic rod 7 is fixedly mounted on the end of the workbench 1 close to the hood 2. The push rod of the first hydraulic rod 7 is fixedly connected to the supporting platform 4 by bolts. The supporting platform 4 is driven by the first hydraulic rod 7 to slide along the guide rod 6 on the workbench 1. When loading and unloading, the supporting platform 4 is located outside the hood 2 to facilitate the staff to take the casting. When cleaning the casting, the casting is moved to the inside of the hood 2 through the supporting platform 4.

[0026] In this embodiment, a groove 41 is provided at the top of the supporting platform 4, and a guide surface 42 inclined to both sides is provided at the bottom of the groove 41. A drain port 43 is opened on the side wall of the supporting platform 4. A waterproof box 44 is fixedly installed in the middle of the guide surface 42, and a second hydraulic rod 45 is fixedly installed in the waterproof box 44. A mesh plate 46 is fixedly installed at the push rod end of the second hydraulic rod 45 by bolts. The casting is placed on the mesh plate 46. When the casting is transported, the top surface of the mesh plate 46 is flush with the top surface of the supporting platform 4 to facilitate the staff to take the casting. When cleaning the workpiece, the push rod of the second hydraulic rod 45 is retracted, and the mesh plate 46 is lowered into the inside of the groove 41 to prevent the casting from interfering with the mesh plate 46 during rotation. The water for cleaning the casting will flow into the groove 41 through the mesh plate 46, and the water in the groove 41 will flow into the water tank 5 through the drain port 43.

[0027] In this embodiment, the clamping mechanism 8 includes a mounting frame 81, which is fixedly mounted on the inner wall of the hood 2. A third hydraulic rod 82 is fixedly mounted on the mounting frame 81. A clamping seat 83 is fixedly mounted on the push rod of the third hydraulic rod 82 by bolts. A clamping plate 84 is rotatably mounted on the end of the clamping seat 83 away from the third hydraulic rod 82. A first motor 86 is fixedly mounted inside the clamping seat 83. The power output shaft of the first motor 86 is connected to the rotating shaft of the clamping plate 84. A support rod 87 is fixedly mounted on the top of the clamping seat 83. The support rod 87 is slidably mounted on the guide frame 3. The clamping seat 83 is suspended on the guide frame 3 through the support rod 87. The clamping seat 83 is driven by the third hydraulic rod 82 to approach the bearing platform 4, and the casting is clamped by the clamping plate 84. After the casting is clamped and fixed, the clamping plate 84 is driven to rotate by the first motor 86, and the clamping plate 84 drives the casting to rotate, thereby cooperating with the spray gun assembly 9 to clean the surface of the casting.

[0028] In this embodiment, a rubber pad 85 is attached to the end surface of the clamping plate 84. When the clamping plate 84 clamps the casting, the rubber pad 85 contacts the casting to increase the friction between the casting and the clamping plate 84 and prevent the casting from slipping.

[0029] In this embodiment, the spray gun assembly 9 includes a high-pressure water gun 91, which is rotatably mounted on a spray gun frame 92, and the spray gun frame 92 is fixedly mounted on the top wall of the hood 2. A second motor 93 is fixedly mounted on the side of the spray gun frame 92, and the power output shaft of the second motor 93 is connected to the rotating shaft of the high-pressure water gun 91. The high-pressure water gun 91 is driven to rotate on the spray gun frame 92 by the second motor 93, and the surface of the casting is cleaned with the cooperation of the high-pressure water gun 91 and the clamping plate 84.

[0030] In this embodiment, a water filter trough 51 and a water storage trough 52 are provided inside the water tank 5, and a filter screen 53 is provided between the water filter trough 51 and the water storage trough 52. The water filter trough 51 is located directly below the clamping assembly. After flushing the casting, the water first flows into the water filter trough 51. The water in the water filter trough 51 is filtered by the filter screen 53 and then flows to the water storage trough 52 for storage. The flushed waste sand is retained in the water filter trough 51 through the filter screen 53.

[0031] In this embodiment, a through groove 10 is opened on the workbench 1, and the through groove 10 is connected with the water filter tank 51. The water after flushing the casting flows into the water filter tank 5 through the through groove 10. A water pump 11 is fixedly installed on the workbench 1. The water inlet of the water pump 11 is connected to the guide pipe 12 through a water pipe (not shown in the figure). The guide pipe 12 is fixedly installed on the workbench 1. The bottom end of the guide pipe 12 is located in the water storage tank 5. The water outlet of the water pump 11 is connected to the high-pressure water gun 91 through a water pipe (not shown in the figure), and the water in the water storage tank 5 is transported to the high-pressure water gun 91 through the water pump 11.

[0032] In this embodiment, a door curtain 13 is fixedly installed at the outlet of the hood 2, and a closed space is formed inside the hood 2 through the door curtain 13 to prevent water from splashing out when the casting is cleaned.

[0033] The specific working process of the utility model is as follows: the push rod of the first hydraulic rod 7 is pushed out to push the bearing platform 4 to the outside of the hood 2, so that the staff can place the casting on the mesh plate 46, and then the push rod of the first hydraulic rod 7 is retracted, and the casting is moved to between the two sets of clamping plates 84 through the bearing platform 4, and the third hydraulic rod 82 drives the clamping seats 3 on the front and rear sides of the bearing platform 4 to approach each other, and the casting on the bearing platform 4 is clamped by the clamping plate 84. After the casting is clamped and fixed, the push rod of the second hydraulic rod 45 is retracted to make the mesh plate 46 drop into the inside of the groove 41, and then the first motor 86 drives the clamping plate 84 to rotate, and the clamping plate 84 drives the casting to The water pump 11 starts to transport the water in the water storage tank 5 to the high-pressure water gun 91 through the water pump 11, and the water is sprayed out from the high-pressure water gun 91. The second motor 93 can drive the high-pressure water gun 91 to rotate on the spray gun frame 92 to cooperate with the clamping plate 84 to clean the surface of the casting, so that there is no need to manually move the casting, which effectively improves the cleaning effect of the casting. The water for cleaning the casting will flow into the groove 41 through the mesh plate 46, and the water in the groove 41 will flow into the filter tank 5 through the drain port 43 and the through groove 10. The water in the filter tank 51 is filtered by the filter screen 53 and then flows to the water storage tank 52 for storage, so that the flushing water can be recycled to save water resources.
