Description

Technical Field

[0001] This utility model relates to the technical field of waste material removal and impurity removal devices, specifically a waste material removal and impurity removal device for casting risers and gating systems. Background Technology

[0002] In the casting process, gating and risers are essential components. Their main function is to guide the molten metal into the mold cavity during the filling process and to provide supplementary metal to the casting during solidification, preventing defects such as shrinkage cavities and porosity.

[0003] Riser gates need to be removed after casting is formed because they are not usually part of the final product. The process of removing risers gates is called "sand removal" or "cleaning". It is a labor-intensive and inefficient process, especially when dealing with large or complex castings. After removal, risers gates are usually recycled and re-enter the casting process. The reuse of recycled materials can significantly reduce production costs and improve resource utilization.

[0004] However, during the removal process, the gating system often accumulates a large amount of impurities, such as sand, oxide scale, and coatings. If these impurities are not effectively removed, they will cause quality problems in the subsequent casting process, such as sand inclusions and porosity. Traditional gating system cleaning mainly relies on manual operation, using tools such as hammers and chisels to knock and clean. This method is not only labor-intensive but also inefficient, making it difficult to meet the needs of large-scale production. Therefore, a casting gating system return material removal impurity device is proposed. Utility Model Content

This device has advantages such as reducing manual intervention and improving cleaning efficiency, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0016] Compared with the prior art, this utility model provides a device for removing impurities from the return material of casting gating and riser, which has the following beneficial effects:

[0017] This casting riser and gating return material impurity removal device effectively removes impurities adhering to the surface of the return material through mutual collision and friction between the return material and the collision and friction between the return material and the inner peripheral wall of the hexagonal rotating frame.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 The casting riser return material removal device in this embodiment includes a base 1, a support frame 2 fixed on the upper surface of the base 1, a removal component 3 on the base 1, a lifting component 4 on the support frame 2, and a material frame 5 placed on the left side of the upper surface of the base 1.

[0025] In this embodiment, the front and rear sides of the upper surface of the material frame 5 are fixed with first fixing rings, and the support frame 2 includes four support rods, with connecting plates fixed at the top of the four support rods.

[0026] Please see Figures 2 to 3 In this embodiment, the impurity removal component 3 includes a fixed frame 301 fixed on the upper surface of the base 1. Two fixed seats 302 are fixed on the fixed frame 301. A rotating column 303 is rotatably connected to the left side of the right fixed seat 302 via a bearing. A rotating rod 304 is rotatably connected to the inside of the left fixed seat 302 via a bearing. A hexagonal rotating frame 305 is fixed on the opposite side of the rotating column 303 and the rotating rod 304. A first motor 306 and a coupling 307 are arranged sequentially from front to back on the upper surface of the fixed frame 301. The left side of the rotating rod 304 is fixedly connected to the outer side of the output shaft of the coupling 307. A transmission wheel 308 is provided on the outer side of the output shaft of the first motor 306 and the outer side of the input shaft of the coupling 307. A belt is movably sleeved on the outer side of the transmission wheels 308 on both the front and rear sides. A fixing member is provided on the hexagonal rotating frame 305.

[0027] Specifically, the fasteners include a cover plate 309 that covers the upper surface of the hexagonal rotating frame 305. Multiple mounting holes 310 are provided at the edges of both the hexagonal rotating frame 305 and the cover plate 309. Bolts are fixed inside the mounting holes 310 on the upper and lower sides to fix the hexagonal rotating frame 305 and the cover plate 309. Multiple discharge holes 311 are provided through the upper surface of the cover plate 309. Second fixing rings are fixed on the left and right sides of the upper surface of the cover plate 309. The multiple discharge holes 311 are evenly distributed on the upper surface of the cover plate 309.

[0028] It should be noted that the casting riser return material is placed into the hexagonal rotating frame 305, and the hexagonal rotating frame 305 and the cover plate 309 are fixed together by the cover plate 309 and bolts. Then, the first motor 306 is started. The first motor 306 drives the rotating rod 304 to rotate through the transmission wheel 308, belt and coupling 307, thereby driving the hexagonal rotating frame 305 to rotate. During the rotation, the return material tumbles inside the hexagonal rotating frame 305. The hexagonal rotating frame 305 rotates at a low speed. The return material inside the hexagonal rotating frame 305 will not break. The return material collides and rubs against each other, and at the same time, the return material collides and rubs against the inner peripheral wall of the hexagonal rotating frame 305, causing the impurities attached to the outside of the return material to detach. Then the impurities are separated and discharged through multiple discharge holes 311. The impurities are discharged through multiple discharge holes 311 as the hexagonal rotating frame 305 rotates.

[0029] Please see Figure 4In this embodiment, the lifting assembly 4 includes a linear module 401 fixed to the top wall of the inner cavity of the support frame 2. A U-shaped frame 402 is provided on the linear module 401. A second motor 403 is fixed to the right side of the U-shaped frame 402. A rotating rod 404 is rotatably connected inside the U-shaped frame 402 through a bearing. The outer side of the output shaft of the second motor 403 rotatably passes through the U-shaped frame 402 and is fixedly connected to the right side of the rotating rod 404. A winding wheel 405 is provided on the outer side of the rotating rod 404, and a winding component is provided on the outer side of the winding wheel 405.

[0030] Specifically, the winding component includes a winding rope 406 disposed on the outside of the winding reel 405. A fixing rod 407 is fixed to the bottom end of the winding rope 406. Connecting ropes 408 are fixed to both the left and right sides of the lower surface of the fixing rod 407. Hooks 409 are fixed to the bottom ends of the connecting ropes 408 on both the left and right sides.

[0031] It should be noted that by starting the second motor 403 and the linear module 401, the hooks 409 on the left and right sides can be driven to move up and down and left and right, which can lift the material frame 5 and move it horizontally so that the hexagonal rotating frame 305 can be loaded. At the same time, the cover plate 309 is lifted by connecting the two hooks 409 to the two second fixed rings.

[0032] The working principle of the above embodiments is as follows:

[0033] In use, the casting riser return material is placed into the hexagonal rotating frame 305. The hexagonal rotating frame 305 and the cover plate 309 are fixed together by the cover plate 309 and bolts. Then, the first motor 306 is started. The first motor 306 drives the rotating rod 304 to rotate through the transmission wheel 308, belt and coupling 307, thereby driving the hexagonal rotating frame 305 to rotate. During the rotation, the return material rolls inside the hexagonal rotating frame 305. The return material collides and rubs against each other. At the same time, the return material collides and rubs against the inner peripheral wall of the hexagonal rotating frame 305, causing the impurities attached to the outside of the return material to detach. Then the impurities are separated and discharged through multiple discharge holes 311. By starting the second motor 403 and the linear module 401, the hooks 409 on the left and right sides can be driven to move up and down and left and right, which can lift the material frame 5 and move it horizontally so that the hexagonal rotating frame 305 can be loaded.
