Description

Technical Field

[0001] This utility model relates to the technical field of mold fixing components, specifically a mold fixing component for electrofused alumina processing. Background Technology

[0002] Fused alumina is a high-performance refractory material widely used in industries such as steel, ceramics, and electronics. When processing fused alumina products, the design and use of mold fixing components are crucial to ensuring product quality and production efficiency.

[0003] Existing mold fixing components can be referenced from Chinese Utility Model Patent Publication No. CN219902083U, which discloses a mold fixing structure including a support plate and a base plate. The support plate is movably mounted on the base plate, and two positioning frames are symmetrically slidably mounted on the support plate. An auxiliary positioning block is movably mounted within each positioning frame. Universal wheels are installed at the four feet of the bottom of the base plate, and an anti-slip plate is movably mounted on the bottom of the base plate. This utility model facilitates the movement of the entire support device by providing universal wheels at the bottom of the base plate; the anti-slip plate is movably mounted on the bottom of the base plate; the two slidably mounted positioning frames on the support plate allow for positioning of the mold to be processed by moving the positioning frames; the movement of the auxiliary positioning blocks assists in positioning, thus better limiting and fixing the mold; and the movable mounting of the support plate on the base plate facilitates control of the height of the support plate after the mold is fixed.

[0004] The above-mentioned device has good performance, but it still has some shortcomings in actual use: The device can move the positioning frame by rotating the second screw, which facilitates the limiting and fixing of the mold. At the same time, the auxiliary positioning block can be moved by adjusting the first screw to better limit and fix the mold, making it highly practical. However, each time the mold is positioned, the operator needs to manually adjust the first and second screws. Since it is a manual adjustment, the operator's experience, force control, judgment errors, etc., will affect the final positioning accuracy, which may lead to the mold not being clamped properly or being clamped too tightly, thus affecting the consistency of product quality or even causing damage to the mold. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a mold fixing assembly for electrofused alumina processing, which has the advantages of automatic and flexible adjustment and good mold fixing effect. Through the cooperation of worm gear and worm, the bidirectional threaded rod is driven to rotate, so that the moving blocks on both sides move towards or away from each other, thereby causing the arc-shaped clamping plate fixed on it to move accordingly, achieving the purpose of clamping the workpiece. At the same time, the auxiliary positioning plate will automatically adjust to the optimal position according to the actual shape of the workpiece through the coordinated action of components such as connecting rods and sliders, ensuring that the workpiece is firmly clamped.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mold fixing assembly for electrofused alumina processing, comprising a mounting plate and a support plate disposed on its top, wherein mounting holes are provided at all four corners of the mounting plate, and the bottom of the support plate is slidably connected to the top of the mounting plate.

[0007] The support plate is provided with a clamping mechanism at its top. The clamping mechanism includes arc-shaped clamping plates on the left and right sides of the top of the support plate.

[0008] As a preferred embodiment of this utility model, each of the four corners of the top of the mounting plate is fixedly connected to an electric push rod. The top telescopic end of the electric push rod is fixedly connected to the four corners of the bottom of the support plate. Each of the left and right sides of the top of the mounting plate is fixedly connected to an L-shaped frame. A limit rod is fixedly connected between the top of the inner wall of the two L-shaped frames and the top of the mounting plate. The limit rod is slidably connected to the left and right sides of the support plate. A controller is fixedly connected to the outer wall of one of the L-shaped frames.

[0009] As a preferred embodiment of this utility model, the support plate is provided with movable blocks on both the left and right sides of its bottom, and the bottom of the two fixed rods is fixedly connected to the top of the two movable blocks respectively. A horizontally arranged bidirectional threaded rod is rotatably connected at the center of the bottom of the support plate, and the left and right sides of the surface of the bidirectional threaded rod are threadedly connected to the two movable blocks respectively.

[0010] As a preferred embodiment of this utility model, both ends of the bidirectional threaded rod are rotatably connected to mounting brackets, the tops of the two mounting brackets are fixedly connected to the bottom left and right ends of the support plate, and a guide rod is fixedly connected between the two mounting brackets on one side close to each other. The guide rod is slidably connected to the two moving blocks.

[0011] In a preferred embodiment of this utility model, a rectangular shell is fixedly connected to the center of the bottom of the support plate, and a worm gear is fixedly sleeved on the center of the inner surface of the rectangular shell. A worm is meshed with the bottom of the worm gear, and a power motor is fixedly connected to the front side of the inner wall of the rectangular shell. The output shaft of the power motor is fixedly connected to the front end of the worm, and the rear end of the worm is rotatably connected to the rear side of the inner wall of the rectangular shell.

[0012] As a preferred embodiment of this utility model, both of the arc-shaped clamping plates are provided with arc-shaped grooves. At least two auxiliary positioning plates are arranged in a circumferential array on the inner wall of each arc-shaped clamping plate. A connecting rod is fixedly connected to the side of each of the two auxiliary positioning plates near the inner wall of the arc-shaped clamping plate. The end of the connecting rod away from the connecting rod extends to the outside of the arc-shaped clamping plate and is slidably connected to the inner wall of the arc-shaped groove.

[0013] In a preferred embodiment of this utility model, an L-shaped plate is fixedly connected to each of the two arc-shaped clamping plates on the side away from each other, and a sliding rod is fixedly connected between the L-shaped plate and the arc-shaped clamping plate on the side closer to each other. A horizontally displaced slider is slidably connected to the surface of the two sliding rods, and an inclined fixed sleeve is rotatably connected to the front and rear ends of each slider. A telescopic rod is slidably connected inside each of the two fixed sleeves.

[0014] In a preferred embodiment of this utility model, the ends of the two telescopic rods away from the fixed sleeve are respectively rotatably connected to the ends of the connecting rod away from the auxiliary positioning plate. The tops of the two L-shaped plates on opposite sides are each fixedly connected to a horizontally arranged second electric push rod. The telescopic end of the second electric push rod is fixedly connected to the top of the slide rod. Each fixed sleeve is provided with a connecting spring that is fixedly connected to the fixed sleeve and the telescopic rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model achieves automated adjustment through the cooperation of the clamping mechanism, which greatly improves work efficiency. The use of a bidirectional threaded rod in conjunction with a worm gear transmission structure ensures that the arc-shaped clamping plate can move accurately towards the center and maintain synchronization, thereby improving clamping accuracy.

[0017] 2. This utility model is started by a power motor, which drives the worm gear to rotate. The worm gear meshes with the worm wheel, transmitting power to the bidirectional threaded rod. As the bidirectional threaded rod rotates, two moving blocks move towards each other along the guide rod under the action of the reverse threads at their left and right ends. The moving blocks drive the arc-shaped clamping plate to move closer to the center of the support plate through the fixed rod. The bottom of the arc-shaped clamping plate is inserted into the guide groove at the top of the support plate through the fixed rod, ensuring that it can only slide in the horizontal direction. When the arc-shaped clamping plate approaches the mold, it forms an initial clamping force to prevent the mold from shifting during subsequent processing. The inner wall of the arc-shaped clamping plate is provided with multiple auxiliary positioning plates distributed in a circle. The auxiliary positioning plates are connected to the slider through connecting rods. The slider is mounted on the sliding rod and can slide laterally between the L-shaped plates. The slider is connected to the telescopic rod through an inclined fixed sleeve and is pushed by the connecting spring, so that the auxiliary positioning plates fit tightly against the outer wall of the mold. This allows the clamping mechanism to adapt to molds of different specifications and improves its versatility. Attached Figure Description

[0027] Example 1

[0028] Reference Figure 1-4 This is the first embodiment of the present invention, which provides a mold fixing assembly for electrofused alumina processing, including a mounting plate 1 and a support plate 2 disposed on its top. The mounting plate 1 has mounting holes 101 at all four corners, and the bottom of the support plate 2 is slidably connected to the top of the mounting plate 1.

[0029] Furthermore, an electric push rod 3 is fixedly connected to each of the four corners of the top of the mounting plate 1. The top telescopic end of the electric push rod 3 is fixedly connected to the bottom four corners of the support plate 2. An L-shaped frame 4 is fixedly connected to the top left and right sides of the top of the mounting plate 1. A limit rod 5 is fixedly connected between the top of the inner wall of the two L-shaped frames 4 and the top of the mounting plate 1. The limit rod 5 is slidably connected to the left and right sides of the support plate 2. A controller 24 is fixedly connected to the outer wall of one of the L-shaped frames 4.

[0030] Specifically, mounting plate 1 is the basic support platform for the entire component, with mounting holes 101 at its four corners for fixing the entire component to the equipment base. Support plate 2 is positioned above the top of mounting plate 1 to support the mold. The bottom of support plate 2 is slidably connected to the top of mounting plate 1, allowing for stable vertical movement. Electric push rod 3 is installed at the four corners of the top of mounting plate 1, with its top telescopic end fixedly connected to the four corners of the bottom of support plate 2, enabling electric lifting control of support plate 2, replacing the traditional manual adjustment method, and improving efficiency and accuracy. L-shaped frame 4 is fixedly connected to the left and right sides of the top of mounting plate 1, providing support and guidance, and enhancing the overall structural stability. Qualitatively, the limiting rod 5 is fixedly connected between the top of the inner wall of the two L-shaped frames 4 and the top of the mounting plate 1. The support plate 2 is slidably connected to the limiting rod 5 through its left and right sides to form a guide and limiting structure, which prevents the support plate 2 from shifting or shaking during the lifting process. The controller 24 is fixed to the outer wall of one of the L-shaped frames 4 and can be used to control the action of the first electric push rod 3, which facilitates automated management. The use of the first electric push rod 3 improves the operating efficiency and positioning accuracy. The L-shaped frame 4 and the limiting rod 5 ensure that the support plate 2 maintains vertical movement during the lifting process, avoids tilting or jamming, and improves the stability of operation. The setting of the controller 24 reduces labor intensity and improves the intelligence level of the equipment.

[0031] Furthermore, the mold to be processed is first placed on the support plate 2. By operating the controller 24, the first electric push rod 3 can be started. The first electric push rod 3 pushes the support plate 2 up or down until it reaches the required height position. As the support plate 2 moves, the presence of the limit rod 5 ensures that the support plate 2 remains stable throughout the process and will not tilt or deviate from the track. Using the first electric push rod 3 not only improves work efficiency but also ensures the consistency and accuracy of each positioning. The positioning and fixing of the mold can be easily completed by simply using the controller 24, which greatly simplifies the operation process and reduces labor intensity.

[0032] Example 2

[0033] In the second embodiment of this utility model, a clamping mechanism is provided on the top of the support plate 2. The clamping mechanism includes arc-shaped clamping plates 6 disposed on the left and right sides of the top of the support plate 2. Horizontally arranged guide grooves 201 are opened on both the left and right sides of the center of the top of the support plate 2. A fixing rod 601 is fixedly connected to the center of the bottom of each of the two arc-shaped clamping plates 6. The bottom of the fixing rod 601 extends to the bottom of the support plate 2 and is slidably connected to the inner wall of the guide groove 201. The moving path of the two arc-shaped clamping plates 6 is to move from the left and right sides of the support plate 2 towards its center. Movable auxiliary components are provided on the inner wall of the two arc-shaped clamping plates 6. The auxiliary components include auxiliary positioning plates 15 arranged in a circumferential array on the inner wall of the arc-shaped clamping plates 6. The auxiliary positioning plates 15 are slidably connected along the inner wall of the arc-shaped clamping plates 6.

[0034] Furthermore, the support plate 2 has movable blocks 7 on both the left and right sides of its bottom. The bottom of the two fixed rods 601 is fixedly connected to the top of the two movable blocks 7 respectively. A horizontally arranged bidirectional threaded rod 8 is rotatably connected at the center of the bottom of the support plate 2. The left and right sides of the surface of the bidirectional threaded rod 8 are threadedly connected to the two movable blocks 7 respectively.

[0035] Furthermore, mounting brackets 9 are rotatably connected to both ends of the bidirectional threaded rod 8. The tops of the two mounting brackets 9 are fixedly connected to the bottom left and right ends of the support plate 2, respectively. Guide rods 10 are fixedly connected between the two mounting brackets 9 on one side close to each other. Guide rods 10 are slidably connected to the two moving blocks 7.

[0036] Furthermore, a rectangular shell 13 is fixedly connected to the bottom center of the support plate 2, and a worm gear 11 is fixedly sleeved on the inner surface center of the double-threaded rod 8. A worm 12 is meshed with the bottom of the worm gear 11. A power motor 14 is fixedly connected to the front side of the inner wall of the rectangular shell 13. The output shaft of the power motor 14 is fixedly connected to the front end of the worm 12, and the rear end of the worm 12 is rotatably connected to the rear side of the inner wall of the rectangular shell 13.

[0037] Furthermore, each of the two arc-shaped clamping plates 6 has an arc-shaped groove 602 with an arc structure. At least two auxiliary positioning plates 15 are arranged in a circumferential array on the inner wall of each arc-shaped clamping plate 6. A connecting rod 16 is fixedly connected to the side of the two auxiliary positioning plates 15 near the inner wall of the arc-shaped clamping plate 6. The end of the connecting rod 16 away from the connecting rod 16 extends to the outside of the arc-shaped clamping plate 6 and slides between it and the inner wall of the arc-shaped groove 602.

[0038] Furthermore, L-shaped plates 17 are fixedly connected to the two arc-shaped clamping plates 6 on the side away from each other, and slide rods 18 are fixedly connected between the L-shaped plates 17 and the arc-shaped clamping plates 6 on the side closer to each other. Horizontally displaced sliders 19 are slidably connected to the surfaces of the two slide rods 18. Each slider 19 is rotatably connected to inclined fixed sleeves 21 at both ends, and telescopic rods 22 are slidably connected inside the two fixed sleeves 21.

[0039] Furthermore, the ends of the two telescopic rods 22 away from the fixed sleeve 21 are rotatably connected to the ends of the connecting rod 16 away from the auxiliary positioning plate 15. The tops of the two L-shaped plates 17 on opposite sides are fixedly connected to horizontally arranged second electric push rods 20. The telescopic ends of the second electric push rods 20 are fixedly connected to the top of the slide rod 18. Each fixed sleeve 21 is provided with a connecting spring 23 that is fixedly connected between the fixed sleeve 21 and the telescopic rod 22.

[0040] Specifically, the arc-shaped clamping plates 6 are symmetrically arranged on the left and right sides of the support plate 2 to clamp the mold. The fixing rod 601 connects the arc-shaped clamping plates 6 and the moving block 7 with the guide groove 201, ensuring that the arc-shaped clamping plates 6 slide in the horizontal direction. The moving block 7 drives the arc-shaped clamping plates 6 to move with the bidirectional threaded rod 8. The bidirectional threaded rod 8 is driven by the power motor 14, which controls the arc-shaped clamping plates 6 to move synchronously towards or away from the center. The auxiliary positioning plate 15 is located inside the arc-shaped clamping plates 6 and can move along the inner wall of the arc-shaped clamping plates 6, further improving the clamping of molds of different sizes. The auxiliary positioning plate 15 and the slider 19 are connected by a connecting rod 16, which allows the auxiliary positioning plate 15 to automatically adjust its position according to the shape of the workpiece. The L-shaped plate 17, the sliding rod 18, and the slider 19 together form an adjustment mechanism that allows the auxiliary positioning plate 15 to move as needed. The second electric push rod 20 is used to drive the slider 19 to move along the sliding rod 18, thereby adjusting the position of the auxiliary positioning plate 15. The fixed sleeve 21, the telescopic rod 22, and the connecting spring 23 work together to enable the auxiliary positioning plate 15 to adapt to molds of different specifications.

[0041] Furthermore, when the controller 24 starts the power motor 14, its output shaft drives the worm 12 to rotate. The worm 12 meshes with the worm wheel 11, driving the bidirectional threaded rod 8 to rotate. The two moving blocks 7 on the bidirectional threaded rod 8 are respectively threaded with its left and right ends. The moving blocks 7 are limited by the guide rod 10 and can only slide in the horizontal direction. As the bidirectional threaded rod 8 rotates, the two moving blocks 7 move towards each other and drive the two arc-shaped clamping plates 6 to move closer to the center of the support plate through the fixed rod 601, thus achieving the initial clamping of the mold.

[0042] Each arc-shaped clamping plate 6 has multiple auxiliary positioning plates 15 arranged in a circular array on its inner wall. The auxiliary positioning plates 15 are connected to the sliders 19 via connecting rods 16. The sliders 19 are mounted on sliding rods 18 and can slide laterally between L-shaped plates 17. The sliders 19 are connected to the connecting rods 16 via inclined fixed sleeves 21 and telescopic rods 22. The end of the telescopic rods 22 is connected to the connecting rods 16 via a rotating shaft. At the same time, each fixed sleeve 21 has a connecting spring 23 inside to provide a rebound force for the telescopic rods 22. The second electric push rod 20 pushes the sliders 19 to move horizontally. When the arc-shaped clamping plate 6 gradually approaches the mold, the auxiliary positioning plates 15 are displaced through the structure of connecting rods 16 and sliders 19. The auxiliary positioning plates 15 can adaptively adjust their positions according to the actual shape to improve clamping stability.

[0043] Working principle:

[0044] This component is placed on the equipment base and fixed through the four mounting holes 101 on the mounting plate 1. The operator starts the first electric push rod 3 through the controller 24 and adjusts the height according to the required height of the mold. The L-shaped frame 4 and the limit rod 5 form a guide system to ensure that the support plate 2 remains stable and does not deviate during the lifting process. After the lifting is in place, the support plate 2 stops rising, the power motor 14 starts, and drives the worm gear 12 to rotate. The worm gear 12 meshes with the worm wheel 11 and transmits power to the bidirectional threaded rod 8. The bidirectional threaded rod 8 rotates, and the two moving blocks 7 move towards each other along the guide rod 10 under the action of the reverse threads at their left and right ends. The moving blocks 7 drive the arc-shaped clamping plate 6 towards the center of the support plate through the fixing rod 601. The bottom of the arc-shaped clamping plate 6 is inserted into the guide groove 201 at the top of the support plate 2 via a fixing rod 601, ensuring that it can only slide in the horizontal direction. When the arc-shaped clamping plate 6 approaches the mold, it forms an initial clamping force to prevent the mold from shifting during subsequent processing. The inner wall of the arc-shaped clamping plate 6 is provided with multiple auxiliary positioning plates 15 arranged in a circle. The auxiliary positioning plates 15 are connected to the slider 19 via a connecting rod 16. The slider 19 is mounted on the sliding rod 18 and can slide laterally between the L-shaped plates 17. The slider 19 is connected to the telescopic rod 22 via an inclined fixing sleeve 21 and is pushed by the connecting spring 23, so that the auxiliary positioning plates 15 fit tightly against the outer wall of the mold, making the clamping mechanism adaptable to molds of different specifications and improving versatility.

[0045] In summary, the clamping mechanism enables automated adjustment, greatly improving work efficiency. The use of a bidirectional threaded rod 8 in conjunction with a worm gear 11 and worm 12 transmission structure ensures that the arc-shaped clamping plate 6 can move precisely towards the center and maintain synchronization, thus improving clamping accuracy.
