[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of 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 efforts shall fall within the protection scope of the present utility model.

[0029] Referring to Figure 1 and Figure 2 , an embodiment provided by the present utility model: a fixing device for a sand mold used in the production of refractory bricks, including a bottom plate 1. An electric motor 15 is fixedly connected to the outside of the bottom plate 1. A fixed groove 8 is opened inside the bottom plate 1. The inner top wall of the fixed groove 8 is rotatably connected to a turntable 12. Two connecting pieces 11 are rotatably connected to the outside of the turntable 12. The other end of the connecting piece 11 is rotatably connected to a slide block 10. The top of the slide block 10 is fixedly connected to an installation block 2. A clamping block 3 is fixedly connected to the outside of the installation block 2. A slide bar 9 is slidably connected to the outside of the slide block 10. The other end of the slide bar 9 is fixedly connected to a connecting piece 13. Two guide grooves 6 are opened at the top of the fixed groove 8. A top mold assembly is installed on the top of the bottom plate 1, and the top mold assembly is used for top molding of fused cast bricks.

[0030] Furthermore, first start the electric motor 15. The output end of the electric motor 15 drives the turntable 12 to rotate. Then, the turntable 12 drives the connecting pieces 11 to rotate simultaneously. Under the traction of the connecting pieces 11, the two slide blocks 10 approach each other along the outside of the slide bar 9. Then, the two installation blocks 2 drive the clamping blocks 3 to approach each other, and the mold body 14 is clamped and fixed by the two clamping blocks 3. Stably clamping the mold body 14 helps to ensure the consistency and quality of the fused cast bricks.

[0031] Referring to Figure 1 、 Figure 2and Figure 3 , the top mold assembly includes a connecting block 4. A moving groove 19 is formed on the outer side of the connecting block 4. A linkage block 18 is fixedly connected to the inner wall of the moving groove 19. A limiting plate 7 is rotatably connected to the outside of the linkage block 18. A spring 20 is fixedly connected to the bottom of the limiting plate 7. A T-shaped block 17 is rotatably connected to the top of the limiting plate 7. A mold body 14 is fixedly connected to the top of the connecting block 4. A support groove 16 is formed at the bottom of the mold body 14; A covering block 5 is slidably connected to the top of the connecting block 4. The covering block 5 is made of ferrosilicon; The longitudinal section of the support groove 16 is T-shaped. The outside of the T-shaped block 17 is slidably connected to the T-shaped block 17; One end of the spring 20 away from the limiting plate 7 is fixedly connected to the inner wall of the moving groove 19.

[0032] Furthermore, when the fused cast refractory is formed, the covering block 5 is removed. By pressing down one end of the limiting plate 7 exposed outside the connecting block 4, under the action of the linkage block 18, the other end of the limiting plate 7 moves upward, thereby driving the T-shaped block 17 to move upward, and then jacking up the fused cast refractory to perform top molding on the formed fused cast refractory. Removing the fused cast refractory in time can reduce the service time of the mold body 14 under high temperature and high pressure conditions and extend the service life of the mold body 14; The function of the covering block 5 is to ensure the tightness of the mold body 14. Ferrosilicon material has good refractory performance and thermal stability; The inner wall of the support groove 16 fits with the T-shaped block 17, making the mold body 14 more reliable and contributing to the stability of product quality; The spring 20 is limited by the limiting plate 7 and the moving groove 19. At the same time, after pressing the limiting plate 7, under the elastic force of the spring 20, the limiting plate 7 can quickly reset.

[0033] Refer to Figure 1 and Figure 2 , one end of the sliding rod 9 away from the connecting piece 13 is fixedly connected to the inner wall of the fixing groove 8. The output end of the motor 15 is fixedly connected to the bottom of the turntable 12; The longitudinal section of the mounting block 2 is square. The outside of the mounting block 2 is slidably connected to the inner wall of the guiding groove 6; The clamping block 3 is shaped like an arc. Anti-slip patterns are provided on the inner side of the clamping block 3.

[0034] Furthermore, the sliding rod 9 is fixed by the fixing groove 8, making the sliding rod 9 more stable and increasing the reliability of the sliding rod 9. The turntable 12 is driven to rotate by the output end of the motor 15; When the slider 10 drives the mounting block 2 to slide, the mounting block 2 slides along the inner wall of the guiding groove 6, further increasing the stability of the mounting block 2 and ensuring the stability of the clamping block 3; The clamping block 3 is designed to be arc-shaped to better fit the mold body 14, achieving a stable clamping effect. The function of the anti-slip patterns is to increase the friction of the clamping block 3 and is beneficial to improving the reliability of the clamping block 3.

[0035] Working principle: First, start the motor 15. The output end of the motor 15 drives the turntable 12 to rotate. Then, the turntable 12 drives the two sliders 10 to approach each other through the connecting member 11. Further, the two mounting blocks 2 drive the clamping blocks 3 to approach each other, clamping and fixing the mold body 14. By clamping and fixing the mold body 14, the mold body 14 always has stability during the process of making the fused cast brick.

[0036] In addition, when the fused cast brick is formed, remove the covering block 5 and press down the limiting plate 7, so that the other end of the limiting plate 7 moves upward. Then, drive the T-shaped block 17 to slide along the support groove 16. At this time, the T-shaped block 17 jacks up the fused cast brick to perform top mold on the formed fused cast brick. In this way, the fused cast brick can be quickly exposed to the air, thereby accelerating the cooling process of its surface and interior.

[0037] 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 recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
