Description

Technical Field

[0001] This utility model relates to the field of refractory brick molding, and more specifically, to a refractory brick molding vibration forming machine. Background Technology

[0002] Refractory bricks, also known as fire bricks, are refractory materials made from refractory clay or other refractory raw materials through firing. They are refractory materials with specific shapes and sizes. Classified by manufacturing process, they can be divided into fired bricks, unfired bricks, electrofused bricks (cast bricks), and refractory insulating bricks. Classified by shape and size, they can be divided into standard bricks, common bricks, and special-shaped bricks. They can be used as high-temperature building and structural materials for kilns and various thermal equipment, and can withstand various physicochemical changes and mechanical actions at high temperatures. Examples include refractory clay bricks, high-alumina bricks, silica bricks, and magnesia bricks. Refractory brick forming molds are mainly used to press the mixture (usually refractory raw materials and binders) into bricks with specific shapes and sizes.

[0003] Based on the above, the inventors have discovered that in the existing refractory brick pressing process, the raw material is mostly added directly into the mold, and then workers use hand tools to break up and smooth the material before pressing. Because the raw material accumulates unevenly after being added to the mold, manual breaking up and smoothing of the accumulated material is required, which is very tedious and reduces the efficiency of brick pressing. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a refractory brick molding vibration molding machine, aiming to achieve a more practical purpose.

An upper mold is fixedly installed at the bottom of the pressure plate via bolts. A lower mold is provided at the top of the pressing table. The positions of the upper mold and the lower mold correspond to each other. A pair of retaining rails are fixedly installed at the top of the pressing table, and a pair of retaining grooves are provided at the bottom of the lower mold. The retaining rails are engaged and installed inside the retaining grooves. A T-shaped fixing plate is fixedly installed on one side of the pressing table. A drive motor is fixedly installed on the back of the vertical end of the T-shaped fixing plate. The output end of the drive motor is connected to a linkage shaft via a coupling, and one end of the linkage shaft is connected via a through groove. A groove passes through the vertical end of the T-shaped fixing plate and is fixedly connected to a disc. A limit rod is fixedly installed on the outer wall of the disc. A rocker arm is installed on the outer wall of the vertical end of the T-shaped fixing plate via a rotating shaft. A toothed block is evenly fixedly installed on the outer edge of the fan-shaped end of the rocker arm. A reciprocating groove is opened on the outer wall of the rocker arm. One end of the limit rod is engaged and installed inside the reciprocating groove. A pair of fixing rings are fixedly installed on the outer wall of the horizontal end of the T-shaped fixing plate. A reciprocating rod is inserted into the inside of the pair of fixing rings. A toothed block is evenly fixedly installed on the outer wall of the reciprocating rod. An opening is opened at the horizontal end of the T-shaped fixing plate. A through groove is opened on the outer wall of the reciprocating rod. A screw is inserted into the through groove. A threaded groove is opened on one side of the outer wall of the lower mold. Handles are fixedly installed on both sides of the lower mold.

[0009] Furthermore, the top of each pair of rails is evenly provided with movable grooves, and ball bearings are movably installed inside the movable grooves.

[0010] Furthermore, one end of the rocker arm is fan-shaped, and the second toothed block on the outer wall of the reciprocating rod meshes with the first toothed block at the fan-shaped end of the rocker arm.

[0011] Furthermore, one end of the screw passes through the through-hole and is connected to the threaded groove on one side of the lower mold via a thread.

[0012] Furthermore, two pairs of fixing blocks are fixedly installed on the top of the pressing table. Each fixing block has a slot on its outer wall. A movable rod is inserted into the slot. A limit connecting block is fixedly installed at the end of each pair of movable rods that is close to each other. A return spring is sleeved on the outside of the movable rod. Limit grooves are opened at the bottom of both sides of the lower mold.

[0013] Furthermore, one end of the reset spring is fixedly connected to the outer wall of the fixing block, and the other end of the reset spring is fixedly connected to the outer wall of the limiting connecting block.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) In this scheme, by setting up a disc, a rocker arm, a reciprocating rod and a screw, after the device is put into use, the lower mold is placed on the top of the pressing table, and the slot at the bottom of the lower mold is engaged with the rail at the bottom of the pressing table. Then, the screw is inserted into the through slot on the reciprocating rod, and one end of the screw passes through the through-hole. The other end of the screw is tightened and fixed to the threaded groove on one side of the lower mold. Then, the worker adds the refractory brick material into the lower mold and drives the motor to work. The drive motor drives the disc to rotate, and the limiting rod on the disc moves back and forth in the reciprocating slot on the rocker arm, so that the rocker arm swings left and right. Then, the tooth block one and tooth block two at one end of the rocker arm mesh and connect, so that the reciprocating rod drives the lower mold to move back and forth left and right through the screw, so that the material inside the lower mold will be broken up and smoothed. When the lower mold stops moving, the hydraulic rod drives the upper mold to press down on the lower mold. This device can effectively improve the efficiency of refractory brick pressing and molding.

[0018] (2) In this solution, by setting up a movable rod, a limiting connecting block, a return spring and a limiting groove, when the lower mold stops moving left and right, the elasticity of the return spring pushes the limiting connecting block so that the position of the lower mold on the pressing table corresponds to the position of the upper mold. This avoids the phenomenon of the upper mold pressing into the lower mold and getting stuck due to the movement of the lower mold. At the same time, by using the limiting connecting block to lock into the inside of the limiting groove, it is possible to facilitate the separation and connection of the lower mold and the limiting connecting block by the staff, thereby improving the convenience of removing the lower mold from the pressing table.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Example:

[0028] Please see Figures 1-5A refractory brick molding vibration molding machine includes a pressing table 1. A fixed table 2 is fixedly installed above the pressing table 1 via a support arm. A hydraulic rod 3 is fixedly installed at the top of the fixed table 2. The telescopic end of the hydraulic rod 3 passes through the fixed table 2 via a through groove and is fixedly installed with a pressure plate 4. An upper mold 5 is fixedly installed at the bottom of the pressure plate 4 by bolts. A lower mold 6 is provided at the top of the pressing table 1. The positions of the upper mold 5 and the lower mold 6 correspond to each other. A pair of retaining rails 7 are fixedly installed at the top of the pressing table 1, and a pair of retaining grooves 8 are opened at the bottom of the lower mold 6. The retaining rails 7 are engaged and installed inside the retaining grooves 8. A hydraulic rod 3 is fixedly installed on one side of the pressing table 1. A T-shaped fixing plate 11 is provided, and a drive motor 12 is fixedly installed on the back of the vertical end of the T-shaped fixing plate 11. The output end of the drive motor 12 is connected to a linkage shaft through a coupling, and one end of the linkage shaft passes through the vertical end of the T-shaped fixing plate 11 through a through groove and is fixedly connected to a disc 13. A limit rod 14 is fixedly installed on the outer wall of the disc 13. A rocker arm 15 is installed on the outer wall of the vertical end of the T-shaped fixing plate 11 through a rotating shaft, and toothed blocks 16 are evenly fixedly installed on the outer edge of the fan-shaped end of the rocker arm 15. A reciprocating groove 17 is opened on the outer wall of the rocker arm 15, and one end of the limit rod 14 is engaged and installed inside the reciprocating groove 17. A pair of fixing rings 18 are fixedly installed on the outer wall of the transverse end of the T-shaped fixing plate 11. A reciprocating rod 19 is inserted into the inner of the pair of fixing rings 18. Tooth blocks 20 are evenly fixedly installed on the outer wall of the reciprocating rod 19. A through-hole 21 is opened at the transverse end of the T-shaped fixing plate 11. A through groove 22 is opened on the outer wall of the reciprocating rod 19. A screw 23 is inserted into the inner of the through groove 22. A threaded groove 24 is opened on one side of the outer wall of the lower mold 6. Handles 31 are fixedly installed on both sides of the lower mold 6. The device drives the disc 13 to rotate through the drive motor 12, so that the limiting rod 14 on the disc 13 can move on the rocker arm 15. The movement of the reciprocating rod 15 in the groove 17 causes the rocker arm 15 to swing back and forth. While the rocker arm 15 swings, the toothed block 16 at one end causes the reciprocating rod 19 to move back and forth left and right through the toothed block 20. The screw 23 on the reciprocating rod 19 can drive the lower mold 6 to move back and forth left and right together. When the movement frequency of the reciprocating rod 19 increases, the lower mold 6 can vibrate left and right, so that the brick raw material inside the lower mold 6 can be fully broken up and smoothed. Then, the upper mold 5 can be driven by the hydraulic rod 3 to press the raw material in the lower mold 6. This device can effectively improve the convenience of placing refractory brick raw materials.

[0029] See Figure 2 , Figure 3 , Figure 5A pair of guide rails 7 have evenly spaced movable grooves 9 at their top ends. Ball bearings 10 are movably installed inside the movable grooves 9. When the lower mold 6 moves left and right reciprocatingly, one end of the guide rail 7 will move in the groove 8 at the bottom of the lower mold 6. Simultaneously, the ball bearings 10 roll within the movable grooves 9 on the guide rail 7, making the movement of the guide rail 7 in the groove 8 more sensitive. One end of the rocker arm 15 is fan-shaped. The second toothed block 20 on the outer wall of the reciprocating rod 19 meshes with the first toothed block 16 at the fan-shaped end of the rocker arm 15. When the rocker arm 15... During the swing, the toothed block 16 at one end can drive the reciprocating rod 19 to move back and forth through the meshing toothed block 20; one end of the screw 23 passes through the through-hole 21 and is connected to the threaded groove 24 on one side of the lower mold 6 by threads. When the lower mold 6 needs to be removed from the pressing table 1, the screw 23 is turned to separate one end of the screw 23 from the threaded groove 24 on one side of the lower mold 6. Then the screw 23 is pulled out from the reciprocating rod 19 to disconnect the lower mold 6 from the reciprocating rod 19, so that the lower mold 6 can be removed from the pressing table 1.

[0030] See Figure 3 , Figure 4 , Figure 5 Two pairs of fixing blocks 25 are fixedly installed on the top of the pressing table 1. Each fixing block 25 has a slot 26 on its outer wall. A movable rod 27 is inserted into the slot 26. A limit connecting block 28 is fixedly installed at the end of each pair of movable rods 27 that is close to each other. A return spring 29 is sleeved on the outside of the movable rod 27. Limit grooves 30 are opened on the bottom of both sides of the lower mold 6. One end of the return spring 29 is fixedly connected to the outer wall of the fixing block 25, and the other end of the return spring 29 is fixedly connected to the outer wall of the limit connecting block 28. The shape of the limit groove 30 and the limit connecting block 28 are the same. It is T-shaped, and the limiting connecting block 28 is inserted into the limiting groove 30. After the lower mold 6 smooths the raw material by reciprocating, the elastic energy of the return spring 29 pushes the limiting connecting block 28 to reset the lower mold 6, thereby improving the accuracy of the upper mold 5 pressing down on the lower mold 6. Furthermore, the limiting connecting block 28 is engaged with the limiting grooves 30 on both sides of the lower mold 6, which can effectively facilitate the workers to pull up and down the lower mold 6, so that the limiting connecting block 28 can be separated from the limiting groove 30, making it easier for the workers to remove the lower mold 6 from the pressing table 1.

[0031] In use: First, the worker fixes the upper mold 5 to the pressure plate 4 with bolts. Then, the lower mold 6 is placed on the top of the pressing table 1, and the slot 8 at the bottom of the lower mold 6 is engaged with the rail 7 at the bottom of the pressing table 1. The limiting connecting block 28 on the pressing table 1 is inserted into the limiting groove 30 on both sides of the lower mold 6 for engagement. Then, the screw 23 is inserted into the through groove 22 on the reciprocating rod 19, and one end of the screw 23 passes through the through opening 21. The screw 23 is then tightened and fixed to the threaded groove 24 on one side of the lower mold 6. Then, the worker adds refractory brick raw materials into the lower mold 6. At the same time, the drive motor 12 starts working, which drives the disc 13 to rotate. Simultaneously, the limiting rod 14 on the disc 13 moves the reciprocating groove 17 on the rocker arm 15 back and forth, causing the rocker arm 15 to swing left and right. Then, by engaging the toothed block 16 and toothed block 20 at one end of the rocker arm 15, the reciprocating rod 19 drives the lower mold 6 to move back and forth through the screw 23, thereby breaking up and smoothing the raw material inside the lower mold 6. When the lower mold 6 stops moving, the elasticity of the return spring 29 pushes the limiting connecting block 28, so that the position of the lower mold 6 on the pressing table 1 corresponds to the position of the upper mold 5. Then, the hydraulic rod 3 drives the upper mold 5 to press the lower mold 6 to form the raw material. After pressing, the hydraulic rod 3 drives the upper mold 5 to return to its original position. Then, the operator loosens the screw 23 from the threaded groove 24 and pulls it off the reciprocating rod 19. Then, the operator can pull the lower mold 6 upward through the handle 31. At the same time, the limiting connecting block 28 separates from the limiting grooves 30 on both sides of the lower mold 6, so that the lower mold 6 can be removed from the pressing table 1 and demolded.

[0032] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
