Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0020] The present utility model provides as Figures 1-3A sand mold for a pig iron accessory based on clay sand is shown, comprising a sand mold body 1, a limiting structure 2 is fixedly arranged at the end of the sand mold body 1, the limiting structure 2 comprises a first limiting sleeve 201 and a second limiting sleeve 202, the first limiting sleeve 201 is sleeved on the end of the sand mold body 1, a limiting groove 203 is provided at the top of the first limiting sleeve 201, the second limiting sleeve 202 is sleeved on the end of the sand mold body 1 away from the first limiting sleeve 201, a limiting block 204 is fixedly arranged on the end surface of the second limiting sleeve 202 away from the first limiting sleeve 201, the limiting block 204 and the inner cavity of the limiting groove 203 are movably interlaced, the first limiting sleeve 201 and the second limiting sleeve 202 are both made of any one of elastic rubber or elastic silicone, the first limiting sleeve 201 and the second limiting sleeve 202 are both provided with grooves on the end surfaces facing the sand mold body 1, the inner walls of the grooves are both serrated, the limiting groove 203 is annular, and the limiting block 204 is cylindrical.

[0021] like Figure 1 and Figure 2 As shown in, the first limiting sleeve 201 and the second limiting sleeve 202 are respectively sleeved on the two ends of the sand mold body 1 with the assistance of external force through their own elastic properties, so that when the sand mold body 1 is stacked, the first limiting sleeve 201 and the second limiting sleeve 202 can be used to make use of the arrangement of the first limiting sleeve 201 and the second limiting sleeve 202, so that the sand mold bodies 1 at adjacent positions above and below can make use of the friction between the first limiting sleeve 201 and the second limiting sleeve 202 to ensure the stability of the position alignment between the adjacent sand mold bodies 1 above and below, and the inner walls of the first limiting sleeve 201 and the second limiting sleeve 202 are both serrated, so that after the first limiting sleeve 201 and the second limiting sleeve 202 are sleeved on the ends of the sand mold body 1, the serrated inner walls can be used to increase the friction resistance with the outer wall of the sand mold body 1, thereby strengthening the first limiting sleeve 201 and the second limiting sleeve 202 sleeved on the sand mold body The stability of the end of the mold body 1 can also prevent the first limit sleeve 201 or the second limit sleeve 202 from falling off due to friction between the sand mold bodies 1 during stacking, and a limit groove 203 and a limit block 204 are respectively arranged on the end faces of the first limit sleeve 201 and the second limit sleeve 202 that are away from each other. The number of the limit blocks 204 is at least one, and the number of the limit blocks 204 is determined according to the needs of use. The limit blocks 204 and the limit grooves 203 are interlaced and connected when the upper and lower adjacent first limit sleeves 201 and second limit sleeves 202 are stacked, so that the first limit sleeve 201 and the second limit sleeve 202 can be horizontally limited by the interlacing of the limit blocks 204 and the limit grooves 203, avoiding left and right deviation when the sand mold bodies 1 are stacked, and effectively improving the stability of the stacked sand mold bodies 1.

[0022] like Figure 1 and Figure 2As shown in the figure, the limiting groove 203 is set in a circular ring shape, so that after the limiting block 204 is interlaced with the inner cavity of the limiting groove 203, it can also rotate along the inner cavity of the limiting groove 203 with the assistance of external force, so that after the sand mold main body 1 is stacked, before taking a single sand mold main body 1, a single sand mold main body 1 can be rotated by external force, so that the sand mold main body 1 can be observed from many aspects, and the subsequent damage to the sand mold main body 1 due to accidental use can be avoided, thereby avoiding reducing the effectiveness of taking and using the sand mold main body 1. Therefore, while effectively enhancing the stacking stability of the sand mold main body 1, it also improves the convenience of observing the damage of the sand mold main body 1.

[0023] A connecting structure 3 is arranged between the second limiting sleeve 202 and the limiting block 204, and the connecting structure 3 includes a connecting rod 301, a connecting groove 302 and a positioning assembly. The connecting groove 302 is opened on the outer wall of the second limiting sleeve 202, the connecting rod 301 is inserted and embedded in the inner cavity of the connecting groove 302, and the positioning assembly is arranged between the connecting rod 301 and the limiting block 204.

[0024] like Figure 2 and Figure 3 As shown in , the connecting rod 301 is a convex shape, and the interlacing engagement between the connecting rod 301 and the connecting groove 302 utilizes the elastic performance of the second limiting sleeve 202, so that the inner cavity of the connecting groove 302 can produce elastic deformation under the action of external force, thereby facilitating the entry of the connecting rod 301, and then after the connecting rod 301 enters the inner cavity of the connecting groove 302, the connecting groove 302 can restore its shape by utilizing the resilience performance of the second limiting sleeve 202, thereby ensuring the interlacing engagement degree between the connecting rod 301 and the connecting groove 302, and at the same time, the end of the connecting rod 301 away from the connecting groove 302 is movably interlaced with one side of the limiting block 204, and the setting of the positioning component is cooperated, so that the connecting rod 301 and the limiting block 204 can be fixed, so that the limiting block 204 can utilize the interlacing engagement between the connecting rod 301 and the connecting groove 302 to ensure the stability of the connection with the outer wall of the second limiting sleeve 202.

[0025] The positioning assembly includes a positioning rod 303, a positioning groove 306 and an elastic assembly. The positioning rod 303 is movably arranged on the outer wall of the positioning rod 303 through the elastic assembly. The positioning groove 306 is opened on the outer wall of the limit block 204. The inner cavity of the positioning rod 303 and the positioning groove 306 are movably interlaced. The elastic assembly includes a movable groove 304 and a spring 305. The movable groove 304 is opened on the outer wall of the connecting rod 301. The spring 305 is fixedly arranged between the connecting rod 301 and the positioning rod 303.

[0026] like Figure 3As shown in the figure, the bottom end of the positioning rod 303 is fixedly arranged with the top end of the spring 305. The positioning rod 303 is inserted into the inner cavity of the positioning groove 306 under the elastic support of the spring 305, so that the connection between the connecting rod 301 and the limiting block 204 can be restricted after being inserted, ensuring the firmness of the connection between the connecting rod 301 and the limiting block 204. At the same time, when the limiting block 204 needs to be disassembled, a downward pressure can be applied to the positioning rod 303 to make the positioning rod 303 move towards the inner cavity of the movable groove 304. After separating from the inner cavity of the positioning groove 306, the restriction on the connection between the limiting block 204 and the connecting rod 301 can be released, enabling the limiting block 204 to be quickly removed from the outer wall of the connecting rod 301. Thus, the disassembly of the limiting block 204 can be completed. On the contrary, the installation between the limiting block 204 and the connecting rod 301 can be quickly carried out, effectively improving the convenience and flexibility of the disassembly and assembly of the limiting block 204. Furthermore, the limiting block 204 can be disassembled and assembled independently, effectively reducing the cost of replacing the limiting block 204. Therefore, the cost of using the limiting structure 2 for the sand mold main body 1 is also reduced.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
