During tundish production, a casting device is used to efficiently shape the refractory material for suitable rotation and subsequent use.

[0003] In the process of using casting equipment, the mold and cover plate form a sealed structure, and refractory material is injected into the mold through the through holes and nozzles on the cover plate. However, in existing casting equipment, the vibration of the mold to eliminate air bubbles during use makes it difficult to ensure the overall stability of the mold. Therefore, an auxiliary device for refractory material casting in an intermediate ladle is proposed to solve the above problems. Utility Model Content

[0006] The second movable block is provided with a support rod, and the other end of the support rod is connected to the limiting plate. The limiting plate is provided with a fixing frame on the top, and the fixing frame is also provided with a second silicone pad on the opposite side.

[0007] The fixing frame has a screw inserted inside, and a second slide rod is provided on one side of the screw. A third movable block is inserted on the screw and the second slide rod, and a pressure plate is provided on one side of the third movable block. A third silicone pad is provided on the lower end face of the pressure plate.

[0008] Preferably, the bidirectional screw, under the action of the servo motor, forms a linkage structure through the first synchronous pulley, the second synchronous pulley, and the synchronous belt, and the limiting plate, under the action of the servo motor, forms a bidirectional limiting sliding structure with the placement frame through the bidirectional screw, the first slide rod, the first movable block, and the placement frame.

[0009] Preferably, the support rod is an inclined structure, and both the support rod and the fixing frame are connected to the placement frame through a bidirectional screw, a first sliding rod, and a second movable block to form a bidirectional limiting sliding structure under the action of the servo motor.

Furthermore, the support rod and the fixing frame are both connected to the placement frame through a two-way screw, a first slide rod, and a second movable block under the action of the servo motor to form a two-way limiting sliding structure. This increases the stability of the limiting plate during operation by synchronously moving and limiting the tilting support rod, and squeezes and limits the two sides of the cover plate through the synchronously moving fixing frame. The pressure plate of this device forms a vertical limiting sliding structure with the cover plate through a screw, a second slide rod, and a third movable block. The height of the pressure plate can be adjusted by the screw assembly, so that the cover plate can be vertically limited by the pressure plate, further ensuring the stability of the cover plate during mold vibration.

[0017] 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.

[0018] Please see Figure 1-4 This utility model provides a technical solution: an auxiliary device for casting refractory tundish in an intermediate ladle, including a mold 14, with a cover plate 15 placed on top of the mold 14. Multiple sets of fixing rings are respectively provided on the outer walls of both sides of the mold 14 and the cover plate 15. An attached vibrator 16 is provided on the outer wall of the mold 14. The mold 14 is placed on a shelf 1, and a servo motor 2 is provided inside the shelf 1. One end of the output shaft of the servo motor 2 is connected to a bidirectional screw 3 via a coupling. A first synchronous pulley is fitted onto one end of the bidirectional screw 3. A second synchronous pulley is correspondingly provided on one side of the first synchronous pulley. A timing belt is fitted onto the second timing pulley, and a bidirectional screw 3 is inserted onto the second timing pulley. A first sliding rod 4 is provided on the outer side of the bidirectional screw 3, and a first movable block 5 and a second movable block 6 are respectively inserted at both ends of the bidirectional screw 3 and the first sliding rod 4. A limiting plate 7 is provided above the first movable block 5, and a first silicone pad is provided on the opposite side of the limiting plate 7. It should be noted that the inner wall of the timing belt in this device is provided with internal teeth that mesh with the external teeth of the first timing pulley and the second timing pulley, thereby ensuring that the first timing pulley and the second timing pulley can move synchronously through the timing belt.

[0019] Furthermore, under the action of the servo motor 2, the bidirectional screw 3 forms a linkage structure through the first synchronous pulley, the second synchronous pulley, and the synchronous belt. Under the action of the servo motor 2, the limiting plate 7 forms a bidirectional limiting sliding structure with the shelf 1 through the bidirectional screw 3, the first slide rod 4, the first movable block 5, and the servo motor 2. Thus, under the action of the synchronous belt, the servo motor 2, and other components, multiple sets of limiting plates 7 can be driven to move relative to each other, so as to squeeze and limit the mold 14 during the vibration casting process through the limiting plate 7, thereby ensuring the stability of the mold 14 during the working process.

[0020] The second movable block 6 is provided with a support rod 8, and the other end of the support rod 8 is connected to the limiting plate 7. The limiting plate 7 is provided with a fixing frame 9 on the upper side, and the fixing frame 9 is also provided with a second silicone pad on the opposite side.

[0021] Furthermore, the support rod 8 is an inclined structure, and the support rod 8 and the fixing frame 9 are both connected to the shelf 1 through the bidirectional screw 3, the first slide rod 4, the second movable block 6 under the action of the servo motor 2 to form a bidirectional limiting sliding structure. Thus, the synchronously moving support rod 8 can further increase the limiting effect of the limiting plate 7 on the mold 14 as a whole. At the same time, the fixing frame 9 and the second silicone pad can simultaneously squeeze and limit both sides of the cover plate 15.

[0022] A screw 10 is inserted inside the fixing frame 9, and a second slide rod 11 is correspondingly provided on one side of the screw 10. A third movable block 12 is inserted through the screw 10 and the second slide rod 11, and a pressure plate 13 is provided on one side of the third movable block 12. A third silicone pad is provided on the lower end face of the pressure plate 13. It should be noted that through holes are respectively opened at both ends of the fixing frame 9 at the screw 10, so as to ensure that the screw 10 can rotate normally. In addition, the multiple sets of movable blocks in this device are correspondingly opened with spiral holes and through holes to ensure that the movable blocks can slide normally with limit. Furthermore, protective plate assemblies of corresponding lengths are installed on the multiple sets of movable blocks according to the required mold size, so as not to affect the normal movement of the movable blocks while allowing the internal movement through the protective plates. The components, such as screws, are protected. In this solution, multiple electrical components are equipped with heat dissipation and vibration reduction structures during installation to ensure the normal operation of the electrical components. This utility model is an auxiliary device for casting refractory materials in an intermediate ladle. All components are standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. In this device, all the aforementioned electrical components refer to power elements, electrical components, and the matching monitoring computer and power supply, which are connected by wires. The specific connection method should refer to the working principle described above, and the electrical connection between each electrical component should be completed in the order of operation. The detailed connection method is a well-known technology in this field.

[0023] Furthermore, the pressure plate 13 forms a vertical limiting sliding structure with the cover plate 15 through the screw 10, the second slide rod 11, and the third movable block 12. Thus, the height-adjustable pressure plate 13 can further squeeze and limit the cover plate 15, thereby ensuring the stability of the cover plate 15 during the intermediate ladle casting process.

[0024] Working Principle: Using the intermediate ladle refractory casting auxiliary device, firstly, the hook on the lifting equipment is placed inside the fixing ring on the mold 14 and cover plate 15. This allows the lifting equipment to move the mold 14 and cover plate 15, placing the mold 14 on the upper surface of the shelf 1. The cover plate 15 is then aligned and placed on the mold 14, forming the shape of the intermediate ladle. This facilitates the subsequent injection of refractory material into the mold 14 through the opening in the cover plate 15. After the mold 14 and cover plate 15 are placed, the servo motor 2 inside the shelf 1 is activated by the control system. One end of the output shaft of the servo motor 2 drives a bidirectional screw 3 to rotate via a coupling. The bidirectional screw 3, in turn, drives another set of bidirectional screws 3 to rotate synchronously via a first synchronous pulley, a second synchronous pulley, and a synchronous belt. This rotation of the bidirectional screws 3 causes the first movable block 5 and the second movable block 6 to move bidirectionally. Simultaneously, the first sliding rod 4 limits the movement of multiple sets of movable blocks, allowing the limited sliding blocks to drive the limiting plates respectively. 7. The support rod 8 slides in both directions to limit the mold 14. The limiting plate 7 can squeeze and limit both sides of the mold 14. The inclined support rod 8 increases the overall limiting effect of the limiting plate 7. When the mold 14 vibrates later, the limiting plate 7 can increase its overall stability. At the same time, the rubber pad between the first silicone pad and the shelf 1 can reduce the impact of vibration on related components. During the operation of the limiting plate 7, the fixing frame 9 squeezes and limits both sides of the cover plate 15 through the second silicone pad. The operator can adjust the height of the third movable block 12 by rotating the screw 10, so that the pressure plate 13 can fit against the surface of the cover plate 15 to squeeze and limit it. This further ensures the overall stability of the cover plate 15 during the vibration of the mold 14. After the mold 14 and cover plate 15 are limited, refractory material can be injected into the casting equipment box. The attached vibrator 16 can prevent the material from generating air bubbles inside the mold, which would affect the subsequent molding effect. This is the usage process of the intermediate ladle refractory casting auxiliary device.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
