Description

Technical Field

[0001] This utility model relates to the field of non-fired brick production technology, specifically to a blank forming device for aluminum silicon carbide carbon brick production. Background Technology

[0002] Silicon carbide alumina carbon bricks, as a high-performance composite refractory material, are widely used in high-temperature industries such as steel, non-ferrous metals, and chemicals due to their high strength, high thermal conductivity, excellent erosion resistance, and thermal shock resistance. They are used in critical components such as blast furnace hearths, furnace bottoms, and linings for non-ferrous metal smelting furnaces. As these high-temperature industries develop towards larger scale, higher efficiency, and longer service life, more stringent requirements are placed on the quality stability, dimensional accuracy, and production efficiency of silicon carbide alumina carbon bricks. The billet forming process, as a core step in the silicon carbide alumina carbon brick production process, directly determines the performance and quality of the final product. Therefore, the optimization and improvement of related forming equipment has become a key demand for industry development. However, existing aluminum silicon carbide carbon brick production billet forming equipment still has some problems in use: First, existing molding equipment generally lacks dedicated blank demolding components, and in actual production, it mostly relies on manual demolding operations. During manual demolding, uneven force applied by the operator can easily lead to problems such as edge and corner damage and internal cracking of the blank, which directly affects the production quality and finished product performance of subsequent aluminum silicon carbide carbon bricks. Secondly, the upper and lower molds of existing molding devices often use complex installation structures such as bolt fastening. This type of installation requires disassembling and calibrating multiple sets of bolts to complete mold replacement, which is not only cumbersome to operate, but also difficult to quickly adapt to the production needs of different specifications of blanks, resulting in excessive downtime for equipment adjustment, which in turn affects production efficiency. Utility Model Content

[0003] In order to solve the problems of poor demolding effect and cumbersome operation when changing molds in existing molding devices, the purpose of this utility model is to provide a molding device for aluminum silicon carbide carbon brick production blanks.

[0004] To solve the above technical problems, the present invention adopts the following technical solution: a blank forming device for producing aluminum silicon carbide carbon bricks, comprising a frame, a cylinder fixedly mounted on the upper surface of the frame, the output end of the cylinder penetrating the upper surface of the frame and fixedly connected to a mounting plate, an upper mold movably mounted on the lower surface of the mounting plate, a lower mold movably engaged with the inner wall of the frame, the lower mold and the upper mold respectively sharing a connecting assembly with the outer surface of the frame and the mounting plate, a demolding assembly sharing a demolding component with the inner cavity and outer surface of the frame, the demolding component comprising a guide shell, the guide shell fixedly mounted on one side of the frame, a DC motor fixedly mounted on the lower surface of the guide shell, the output end of the DC motor penetrating the lower surface of the guide shell and fixedly connected to a lead screw, the top end of the lead screw rotatably connected to the inner wall of the guide shell, a slider threaded on the outer surface of the lead screw, a connecting rod fixedly connected to one side of the slider, a guide groove opened on one side of the frame, the side of the connecting rod away from the slider penetrating the guide groove and fixedly connected to a support plate, and a demolding component movably mounted on the upper surface of the support plate.

[0005] Preferably, the connecting assembly includes symmetrically distributed first locking blocks, which are symmetrically fixedly installed on the upper surface of the upper mold and movably engaged with the lower surface of the mounting plate. A first magnetic pin is magnetically inserted between the upper mold and the mounting plate. Second locking blocks are symmetrically fixedly connected to both sides of the lower mold. The inner wall of the frame is symmetrically provided with slots for cooperating with the second locking blocks. Correspondingly, the second locking blocks are movably engaged with the slots. The second locking blocks and the outer surface of the frame are magnetically engaged with a second magnetic pin.

[0006] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This application adds a dedicated demolding component and uses electric drive to control the demolding component to be inserted into the lower mold. This design can realize the rapid and stable demolding of the molded blank, effectively avoid the damage to the edge corners or internal cracks of the blank caused by uneven force during manual operation, significantly reduce the production loss of aluminum silicon carbide carbon bricks, and thus ensure the production quality of the molding device and the performance of the final product. 2.

[0012] 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.

[0013] Example: Figure 1-3As shown, this utility model provides a blank forming device for producing aluminum silicon carbide carbon bricks, including a frame 1. A cylinder 4 is fixedly installed on the upper surface of the frame 1, and the output end of the cylinder 4 passes through the upper surface of the frame 1 and is fixedly connected to an mounting plate 5. An upper mold 7 is movably provided on the lower surface of the mounting plate 5, and a lower mold 6 is movably engaged with the inner wall of the frame 1. The upper mold 7 and the lower mold 6 are arranged vertically. The cylinder 4 can drive the mounting plate 5 to move the upper mold 7 up and down, realizing the mold closing and pressing with the lower mold 6. The lower mold 6 and the upper mold 7 are respectively provided with a connecting component 3 on the outer surface of the frame 1 and the mounting plate 5. The connecting component 3 facilitates the quick assembly and disassembly of the upper mold 7 and the lower mold 6. The inner cavity and the outer surface of the frame 1 are provided with a demolding component 2, which realizes automatic demolding. The overall structure is compact, and the coordinated work of each component ensures the efficient progress of the forming process.

[0014] The demolding assembly 2 includes a guide shell 202, which is fixedly installed on one side of the frame 1. A DC motor 27 is fixedly installed on the lower surface of the guide shell 202, and a bracket 28 for use with the DC motor 27 is fixedly installed on the lower surface of the guide shell 202. The DC motor 27 is fixedly installed on the inner wall of the bracket 28, which ensures that the DC motor 27 is firmly installed. The output end of the DC motor 27 passes through the lower surface of the guide shell 202 and is fixedly connected to a lead screw 201. The DC motor 27 drives the lead screw 201 to rotate. The top end of the lead screw 201 is rotatably connected to the inner wall of the guide shell 202 to ensure the stability of the rotation of the lead screw 201.

[0015] The outer surface of the lead screw 201 is threaded with a slider 29, and a connecting rod 22 is fixedly connected to one side of the slider 29. A guide groove 21 is provided on one side of the frame 1. The outer surface of the slider 29 is slidably connected to the inner cavity of the guide shell 202. The lead screw 201 drives the slider 29 to slide along the guide shell 202. The connecting rod 22 is slidably connected to the guide groove 21. The side of the connecting rod 22 away from the slider 29 passes through the guide groove 21 and is fixedly connected to a support plate 26. A demolding component 24 is movably installed on the upper surface of the support plate 26. Through the cooperation of the connecting rod 22 and the guide groove 21, the support plate 26 can be smoothly raised and lowered, thereby driving the demolding component 24 to complete the demolding action, replacing manual operation and reducing the damage to the blank.

[0016] The lower surface of the demolding component 24 is symmetrically and fixedly connected with guide strips 25. The guide strips 25 are movably inserted into the upper surface of the support plate 26. The insertion between the guide strips 25 and the support plate 26 has damping properties, which can increase the stability of the demolding component 24 during installation. A third magnetic pin 23 is magnetically inserted between the demolding component 24 and the support plate 26. The guide strips 25 ensure the precise docking of the demolding component 24 and the support plate 26. The third magnetic pin 23 enables the quick assembly and disassembly of the demolding component 24, which is convenient for adapting to the demolding requirements of different specifications of blanks.

[0017] The connecting component 3 includes symmetrically distributed first locking blocks 31, which are symmetrically fixedly installed on the upper surface of the upper mold 7. The first locking blocks 31 are movably locked onto the lower surface of the mounting plate 5, and the locking here also has damping properties. The cross-sectional shape of the first locking blocks 31 is T-shaped. A first magnetic pin 32 is magnetically inserted between the upper mold 7 and the mounting plate 5. The T-shaped first locking blocks 31 are locked onto the mounting plate 5. Combined with the magnetic fixation of the first magnetic pin 32, the upper mold 7 and the mounting plate 5 can be quickly positioned and connected, and the assembly and disassembly are convenient.

[0018] The lower mold 6 is symmetrically fixedly connected to two sides with second locking blocks 35. The inner wall of the frame 1 is symmetrically provided with locking slots 34 for use with the second locking blocks 35. The corresponding second locking blocks 35 are movably engaged with the locking slots 34. The engagement here is also damped. The second locking blocks 35 and the outer surface of the frame 1 are magnetically connected to the second magnetic pins 33. The engagement of the second locking blocks 35 and the locking slots 34, combined with the fixation of the second magnetic pins 33, makes the installation of the lower mold 6 and the frame 1 stable and easy to replace. The overall connection component 3 replaces the traditional bolt connection with plug-in and magnetic attraction, which greatly shortens the downtime for mold replacement and improves production efficiency.

[0019] Working principle: First, the upper mold 7 and the lower mold 6 are installed by connecting component 3. The T-shaped first locking block 31 on the upper surface of the upper mold 7 is inserted into the corresponding groove on the lower surface of the mounting plate 5. Then, the first magnetic pin 32 is inserted to fix the upper mold 7 and the mounting plate 5.

[0020] Align the second locking blocks 35 on both sides of the lower mold 6 with the locking slots 34 on the inner wall of the frame 1 and insert them. Insert the second magnetic pins 33 to fix the lower mold 6 to the frame 1. At this time, the upper mold 7 and the lower mold 6 are in an upper-lower corresponding state.

[0021] Then, the aluminum silicon carbide carbon brick blank is placed into the cavity of the lower mold 6, the cylinder 4 is started, the output end of the cylinder 4 pushes the mounting plate 5 to move the upper mold 7 downward, so that the upper mold 7 and the lower mold 6 are closed, and the blank is pressed and shaped.

[0022] During demolding, the DC motor 27 in the demolding assembly 2 is started. The DC motor 27 drives the lead screw 201 to rotate inside the guide shell 202. The lead screw 201 drives the slider 29 to slide along the inner cavity of the guide shell 202. The slider 29 pushes the support plate 26 upward through the connecting rod 22, so that the demolding part 24 on the support plate 26 is inserted into the bottom of the cavity of the lower mold 6.

[0023] As the support plate 26 continues to rise, the demolding component 24 pushes the formed blank out of the lower mold 6, completing the automatic demolding.

[0024] When it is necessary to change to a mold or demolding part 24 of different specifications, the first magnetic pin 32 and the second magnetic pin 33 can be pulled out to quickly disassemble and replace the upper mold 7 and the lower mold 6.

[0025] Pulling out the third magnetic pin 23 allows the demolding part 24, along with the guide strip 25, to be removed from the support plate 26 for replacement, adapting to the production needs of blanks of different specifications.

[0026] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
