In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0018] like Figure 1-2 As shown, a sand box suitable for slag basin molding: comprising a sand box body 1, a sand mold cavity 2 is arranged in the sand box body, a slag basin wooden mold 3 is arranged inside the sand mold cavity, a sand filling area 4 is formed between the outer wall of the slag basin wooden mold and the inner wall of the sand mold cavity, and a wooden mold limiting structure is arranged on the inner wall of the sand mold cavity; the side wall of the sand box body is an inclined surface corresponding to the slag basin wooden mold, and when in use, the slag basin wooden mold is stably fixed in the sand box body by the wooden mold limiting structure, and then the sand filling amount is reduced by the inclined side wall of the sand box body.

[0019] In this embodiment, for the sake of reasonable design, the sand box body includes an upper sand box 5, a middle sand box 6, and a lower sand box 7 which are overlapped in sequence from top to bottom. The construction of the sand box body is realized by three layers of sand boxes. At the same time, the lower sand box is overlapped on a bottom plate 8. The upper sand box, the middle sand box, and the lower sand box all include an inner frame wall 9. The upper and lower ends of the inner frame wall are horizontally bent outward to form an upper overlap plate 10 and a lower overlap plate 11. Ribs 12 connecting the upper overlap plate and the lower overlap plate are evenly distributed on the outer wall of the inner frame wall. The ribs are used to reinforce the structure. The lower overlap plate of the upper sand box is overlapped on the upper overlap plate of the middle sand box, and the lower overlap plate of the middle sand box is overlapped on the upper overlap plate of the lower sand box.

[0020] In this embodiment, transverse connecting columns 13 for lifting the sand boxes are symmetrically arranged on the left and right outer walls of the inner frame wall and the bottom plate to facilitate the movement of each layer of sand boxes.

[0021] In this embodiment, for the sake of reasonable design, the inner frame walls of the middle sand box and the lower sand box are both inclined walls with a larger upper opening and a lower opening, the inclination degree of the middle sand box and the lower sand box matches the outer wall of the wooden mold, the inner frame wall of the upper sand box is a vertical wall, the lower opening of the middle sand box is butt-jointed with the upper opening of the lower sand box, the lower opening of the upper sand box is butt-jointed with the upper opening of the middle sand box, the lower end surface of the lower sand box is overlapped on the bottom plate, the inner frame walls of the upper sand box, the middle sand box and the lower sand box and the bottom plate form a sand mold cavity, and since the upper sand box is already close to the bottom of the wooden mold, that is, close to the smallest size of the wooden mold, it does not need to be tilted additionally.

[0022] In this embodiment, in order to place the lower sand box, limiting grooves 14 are provided at the four corners of the bottom plate, and limiting blocks 15 are provided on the lower lap plate of the lower sand box corresponding to the limiting grooves to facilitate the positioning and placement of the lower sand box.

[0023] In this embodiment, the wooden mold limiting structure includes a plurality of vertical limiting plates 16, which are distributed on the inner wall of the sand mold cavity at intervals, that is, the vertical limiting plates are arranged around the inner wall of the sand mold cavity, and the inner edges of the vertical limiting plates are abutted against the outer wall of the slag basin wooden mold. Each vertical limiting plate is divided into upper, middle and lower three split limiting plates 17 corresponding to the upper sand box, the middle sand box and the lower sand box, and the outer edges of the split limiting plates are connected to the inner walls of the inner frame walls of the corresponding upper sand box, the middle sand box and the lower sand box. The middle wooden mold is limited by the vertical limiting plates so that the wall thickness of the filled molding sand is uniform. At the same time, since each vertical limiting plate is divided into upper, middle and lower three split limiting plates corresponding to the upper sand box, the middle sand box and the lower sand box can complete the overlap by sliding them onto the wooden mold through the corresponding split limiting plates after the molding sand 18 is filled in the sand box below.

[0024] In this embodiment, for the sake of reasonable design, the slag basin wooden mold is in the shape of a basin, with the basin mouth of the slag basin wooden mold facing downward and inverted on the bottom plate, and a yield groove 19 is provided on the bottom plate corresponding to the basin edge of the slag basin wooden mold, and a filling port 20 is provided on the bottom of the slag basin wooden mold.
