[0025] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0026] like Figure 1-4 As shown, this utility model provides a technical solution: a sand-casting device for processing castings, including a body 1, a worktable 2 on one side of the body 1, a hydraulic plate 3 on one side of the body 1, and a leveling device 4 on one side of the body 1. The leveling device 4 includes a perforated plate 41, an adjusting device 5 between the perforated plate 41 and the body 1, a motor 42 fixedly connected to one side of the perforated plate 41, a perforated rod 43 fixedly connected to the output end of the motor 42, a round rod 44 slidably connected to the inner wall of the perforated rod 43, a spring 45 sleeved on the surface of the round rod 44, one end of the spring 45 fixedly connected to the round rod 44, and the other end of the spring 45 fixedly connected to the perforated rod 43. A scraper 46 is fixedly connected to one side. By setting a leveling device 4, after the hydraulic plate 3 flattens the sand inside the sand box, the motor 42 is started, which drives the round hole rod 43 to rotate, which in turn drives the round rod 44 to rotate, which in turn drives the scraper 46 to rotate. When the scraper 46 rotates to the position where it is in contact with the top layer of the sand box, under the extension and contraction of the spring 45, the scraper 46 can move up and down and come into contact with the surface of the top layer of the box. The scraper 46 slides against the surface of the top layer of the sand box and scrapes off the excess sand, thereby completing the leveling of the top layer of the sand box. This reduces the number of steps and time required to remove excess sand from the top layer of the sand box and improves the leveling efficiency of the sand box.

[0027] Specifically, such as Figure 2 and Figure 3As shown, a baffle 47 is fixedly connected to one side of the scraper 46. The cross-section of the baffle 47 is arc-shaped. By setting the baffle 47, the scraped sand can be intercepted, reducing the occurrence of scraped sand rolling over the surface of the scraper 46. A screw 48 is fixedly connected to the side of the round rod 43 near the round rod 44. A round hole pressure plate 49 is fitted on the surface of the screw 48. A threaded hole ring 410 is threaded onto the surface of the screw 48. The surface of the threaded hole ring 410 is larger than the inner wall of the round hole pressure plate 49. By setting the round hole pressure plate 49, the round hole pressure plate 49 is first fitted onto the surface of the screw 48 and fits against the round rod 44. At this time, the threaded hole ring 410 is manually rotated so that the threaded hole ring 410 moves along the surface of the screw 48. The downward movement causes the screw ring 410 to press and limit the round rod 44 through the round hole pressure plate 49, which in turn causes the round rod 44 to move the scraper 46 up and down, thereby achieving the positioning of the scraper 46 height. This allows the scraper 46 to be fixed in a designated position, making it easier to control the leveling height. A positioning block 411 is fixedly connected to one side of the round rod 44. The surface size and shape of the positioning block 411 are adapted to the size and shape of the inner wall of the round hole pressure plate 49. By setting the positioning block 411, it can enter the interior of the round hole pressure plate 49 to assist in limiting its movement, reducing the possibility of the round hole pressure plate 49 rotating or shaking during the pressing process of the screw ring 410.

[0028] Specifically, such as Figure 2 and Figure 4 As shown, the adjustment device 5 includes a rectangular frame 51, which is fixedly connected to the machine body 1. A bolt 52 is provided inside the rectangular frame 51. A screw hole block 55 is fixedly connected to one side of the circular hole plate 41. The surface of the screw hole block 55 is slidably connected to the inner wall of the rectangular frame 51. The surface of the bolt 52 is threadedly connected to the inner wall of the screw hole block 55. By setting the adjustment device 5, the circular hole plate 41 is first manually moved, so that the circular hole plate 41 drives the screw hole block 55 to move up and down along the inside of the rectangular frame 51. When the screw hole block 55 moves to the position where the inner wall coincides with the inner wall of any hole on the rectangular frame 51, the bolt 52 is manually rotated, so that the bolt 52 rotates into the position of the hole on the rectangular frame 51 and the inside of the screw hole block 55, fixing the position of the screw hole block 55 and the circular hole plate 41. This completes the height adjustment of the leveling device 4, so that the leveling device 4 can be adapted to various sand boxes of different sizes for leveling operations, improving the flexibility and practicality of the leveling device 4.

[0029] Specifically, such as Figure 2 and Figure 4As shown, a screw block 53 is fixedly connected to one end of the bolt 52. The surface of the screw block 53 has multiple grooves. By setting the screw block 53, the contact area of ​​the bolt 52 can be increased, allowing personnel to quickly rotate the bolt 52 by manually rotating the screw block 53, thus improving the convenience of manually rotating the bolt 52. A limit block 54 is fixedly connected to the inner wall of the rectangular frame 51. A limit groove 56 is opened on one side of the screw hole block 55. The surface of the limit block 54 is slidably connected to the inner wall of the limit groove 56. By setting the limit block 54 and the limit groove 56, the limit block 54 can be located inside the limit groove 56 to assist in limiting the screw hole block 55, reducing the shaking of the screw hole block 55 when it moves along the inside of the rectangular frame 51, and improving the stability of the screw hole block 55.

[0030] The working principle of this utility model is as follows:

[0031] S1. First, manually move the circular hole plate 41 so that the circular hole plate 41 drives the screw hole block 55 to move up and down along the inside of the rectangular frame 51. When the screw hole block 55 moves to the position where the inner wall coincides with the inner wall of any hole on the rectangular frame 51, manually rotate the screw block 53 so that the screw block 53 drives the bolt 52 to rotate, so that the bolt 52 rotates into the position of the hole on the rectangular frame 51 and the inside of the screw hole block 55 to fix the position of the screw hole block 55 and the circular hole plate 41, thereby completing the height adjustment of the scraping device 4.

[0032] S2. At this time, place the sand box on the workbench 2, and then fill the sand box. Use the hydraulic plate 3 above the machine body 1 to flatten the sand inside the sand box. At this time, start the motor 42, so that the motor 42 drives the round hole rod 43 to rotate, so that the round hole rod 43 drives the round rod 44 to rotate, so that the round rod 44 drives the scraper 46 to rotate. When the scraper 46 rotates to the position of contacting the top layer of the sand box, under the extension and contraction of the spring 45, the scraper 46 can move up and down and contact the surface of the top layer of the box. The scraper 46 slides against the surface of the top layer of the sand box and scrapes off the excess sand, thereby completing the flattening of the top layer of the sand box and achieving the shaping of the sand mold.

[0033] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components.

[0034] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
