Description

Technical Field

[0001] This invention relates to the field of red brick forming mold technology, specifically a red brick forming device with a quick mold changing function. Background Technology

[0002] Red bricks are sintered building bricks made from clay, shale, and coal gangue, which are crushed, mixed, kneaded, and then pressed into shape by hand or machine. After drying, they are fired in an oxidizing flame at a temperature of about 900 degrees Celsius.

[0003] Currently, before pressing red bricks, various raw materials (such as clay, shale, and coal gangue) need to be mixed in proportion. The mixed raw materials are then poured into the inside of a pressing mold (the pressing mold has multiple partitions installed inside, which can evenly divide the inside of the pressing mold into spaces of equal area, which is conducive to pressing multiple sets of raw materials at the same time). Then, a pressure plate is used to squeeze the raw materials in the mold (the squeezing process can subject raw materials such as clay to strong pressure in the mold, thereby expelling air and excess moisture, making the bricks denser). This not only improves the physical properties of the bricks but also reduces cracking and deformation during use. The squeezed raw materials are then dried, and after drying, they are fired to complete the production of red bricks.

[0004] In the prior art, a top plate is slidably installed at the bottom of the inner cavity of the pressing mold, and a freely retractable hydraulic cylinder is installed at the bottom of the top plate. When it enters the interior of the pressing mold, the top of the top plate is parallel to the bottom of the inner cavity of the pressing mold (to prevent unevenness at the bottom of the extruded material and to support the bottom of the material to prevent leakage from the bottom of the pressing mold). After the material is extruded and shaped, the hydraulic cylinder is activated to move the top plate upward. At this time, the top plate can push the shaped material upward to facilitate the extraction and transfer of the extruded material from the pressing mold. After the extruded material is extracted from the pressing mold, the hydraulic cylinder is activated to move the top plate downward until the top plate is reset to facilitate the extrusion and shaping of the next batch of material.

[0005] Due to varying construction requirements, the sizes of the red bricks to be fired differ. Therefore, different sized pressing molds are needed to replace the bricks. Currently, replacing the pressing mold involves first dismantling it, then separating multiple top plates from the power output of the hydraulic cylinder. A pressing mold matching the required brick size is then reinstalled, and a matching top plate is placed inside. Finally, the bottom of the top plate is installed to the power output of the hydraulic cylinder. However, traditionally, the top plates and the power output of the hydraulic cylinder are connected by bolts and nuts. Disassembling and assembling these requires using tools to fix the large end of the bolts and then continuously rotating the small end until the bolt and nut are completely separated. Because there are many top plates (the number of top plates is the same as the number of chambers formed after the pressing mold is divided), the distance between the top plates is small. This makes it difficult to continuously rotate the nuts when disassembling and assembling the top plates and the power output of the hydraulic cylinder. The position of the tools relative to the nuts needs constant adjustment, increasing the time and effort required for pressing mold replacement and reducing its efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide a brick forming device with a rapid mold changing function to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a red brick forming device with a rapid mold changing function, comprising;

[0009] The top plate is slidably installed in the inner cavity of the pressing mold, and a sliding plate is fixedly installed at the bottom of the top plate. The bottom of the inner cavity of the pressing mold is provided with a guide hole that matches the sliding plate. The bottom of the sliding plate passes through the guide hole and extends to the bottom of the pressing mold. A drive plate for sliding itself is fixedly installed at the bottom of the sliding plate.

[0010] A hydraulic cylinder is fixedly connected to the top of the base plate at one end. A drive block is fixedly installed at the power output end of the hydraulic cylinder. An installation groove is opened on the top of the drive block. A connecting block is detachably installed in the inner cavity of the installation groove.

[0011] Two fixing slots are symmetrically opened on both sides of the drive block. A fixing strip can be detachably installed in the inner cavity of one of the fixing slots. A limiting hole is opened on one side of the connecting block and communicates with the other side of itself.

[0012] The fixing frame is detachably sleeved on the outside of the fixing strip, and a positioning post is slidably installed on one side of the fixing frame. A fixing hole that matches the positioning post is opened on one side of the fixing strip.

[0016] Preferably, the limiting component includes a limiting frame and a vertical block. The limiting frame is fixedly sleeved on the outside of the pressing mold. One side of the vertical block is fixedly connected to one side of the bearing frame, and both sides of the vertical block are provided with sliding grooves. Sliding blocks are installed in the inner cavities of the two sliding grooves. A U-shaped frame is provided on the outside of the vertical block. The two sides of the inner cavity of the U-shaped frame are rotatably connected to the two sliding blocks at opposite ends via rotating shafts. A pressure block adapted to the U-shaped frame is fixedly installed on the side of the limiting frame near the vertical block.

At this time, the connecting block is pulled out from the inside of the mounting groove. The disassembly of the pressing mold is completed when the drive plate is completely pulled out from the inside of the support frame and moved to the top of the support frame. This reduces the time and effort required to replace the pressing mold and improves the efficiency of the pressing mold replacement. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] Please see Figure 1-8 ,include:

[0035] The base plate 1 has a support frame 3 fixedly installed on top. Support legs are fixedly installed at the four corners of the top of the base plate 1, and the tops of the four support legs are fixedly connected to the four corners of the bottom of the support frame 3 for supporting the support frame 3. A pressing device for extruding red brick raw materials is installed on the top of the support frame 3. The red brick raw materials can be quickly extruded and shaped using the pressing device (this is existing technology and will not be elaborated further here).

[0036] The inner cavity of the support frame 3 is detachably equipped with a pressing mold 6 for the production of red bricks. After the red brick raw materials (such as clay, shale and coal gangue) are proportioned, they are poured into the inside of the pressing mold 6. Then the raw materials in the pressing mold 6 are spread out, and the red brick raw materials in the pressing mold 6 can be pressed into shape by pressing equipment multiple times.

[0037] The outer side of the support frame 3 is provided with a limiting component for limiting the pressing mold 6. The pressing mold 6 placed inside the support frame 3 can be positioned by the limiting component to prevent the pressing mold 6 from falling out of the support frame 3 and to avoid the pressing mold 6 shaking when the red brick raw material inside the pressing mold 6 is squeezed, thereby improving the stability of the red brick raw material when it is squeezed.

[0038] The top plate 11 is slidably installed in the inner cavity of the pressing mold 6, and the bottom of the top plate 11 is fixedly installed with a sliding plate 2. The bottom of the inner cavity of the pressing mold 6 is provided with a guide hole that matches the sliding plate 2. The sliding plate 2 can slide up and down along its own axis through the guide hole, thereby limiting the sliding trajectory of the top plate 11 and improving the stability of the top plate 11 moving up and down.

[0039] The pressing mold 6 has multiple partitions installed inside, which can divide the interior of the pressing mold 6 into multiple cavities of the same area. Each of the multiple cavities can be filled with red brick raw materials. The pressing equipment can press the red brick raw materials in multiple cavities at the same time, thereby increasing the pressing rate of the red brick raw materials.

[0040] The bottom of the inner cavity of the pressing mold 6 is provided with multiple guide holes. The number of guide holes is the same as the number of cavities formed by the partition. The guide holes and the cavities formed by the partition correspond one-to-one. After the red brick material is extruded and formed in the multiple cavities, the sliding plate 2 is pushed to move the top plate 11 upward. The top plate 11 applies a pushing force to the bottom of the red brick material, which can move the formed red brick material upward so that the extruded red brick material can be manually extracted from the inside of the pressing mold 6.

[0041] The bottom of the inner cavity of the pressing mold 6 is provided with a groove that matches the top plate 11. The inner cavity of the groove and the inner cavity of the guide hole are connected to each other. After the top plate 11 is lowered and reset, the bottom of the top plate 11 and the inner wall of the groove away from its own opening end fit together, thereby limiting the downward position of the top plate 11. At the same time, the top of the top plate 11 is flush with the bottom of the inner cavity of the pressing mold 6, preventing unevenness on the side wall after the red brick raw material is squeezed, and improving the uniformity of the red brick surface.

[0042] The bottom of the slide plate 2 passes through the guide hole and extends directly below the pressing mold 6. The bottom of the slide plate 2 is fixedly installed with a drive plate 12 for sliding itself. The bottoms of multiple slide plates 2 are fixedly connected to the top of the drive plate 12. By pushing the drive plate 12, multiple slide plates 2 can move up and down synchronously, which improves the convenience and synchronization of the up and down movement of multiple slide plates 2.

[0043] A hydraulic cylinder is fixedly connected at one end to the top of the base plate 1. A drive block 9 is fixedly installed at the power output end of the hydraulic cylinder. An installation groove is opened on the top of the drive block 9. A connecting block 8 is detachably installed in the inner cavity of the installation groove. The top of the connecting block 8 is fixedly connected to the bottom of the drive plate 12. When the connecting block 8 is inserted into the installation groove and fixed, when the hydraulic cylinder is started, the drive block 9 moves up and down with the power output end of the hydraulic cylinder. When the drive block 9 moves up and down, the connecting block 8 moves accordingly. When the connecting block 8 moves up and down, the drive plate 12 moves with the connecting block 8, thereby causing the top plate 11 to move up and down. When the top plate 11 moves up, it can push out the red brick raw material located inside the pressing mold 6. After the extruded red brick raw material is taken out from inside the pressing mold 6, the connecting block 8 moves down, which allows multiple top plates 11 to reset simultaneously. This is beneficial for pouring the next batch of red brick raw material into the pressing mold 6 and pressing it into shape.

[0044] Two fixing slots 13 are symmetrically opened on both sides of the drive block 9. A fixing strip 10 is detachably installed in the inner cavity of one of the fixing slots 13. A limiting hole 14 is opened on one side of the connecting block 8 and communicates with the other side of itself. When the bottom of the connecting block 8 is inserted into the mounting slot and fits against the inner wall of the mounting slot away from its own opening end, the middle of the two fixing slots 13 and the middle of the opening end of the limiting hole 14 are on the same horizontal line. Then, the small end of the fixing strip 10 is inserted into the inside of the limiting hole 14 through one of the fixing slots 13, and extends through the limiting hole 14 and the other fixing slot 13 to the other side of the drive block 9. This completes the connection between the connecting block 8 and the drive block 9, preventing the connecting block 8 from detaching from the inside of the mounting slot and allowing the connecting block 8 to move synchronously with the drive block 9.

[0045] The fixing strip 10 is set as a T-shaped structure. The larger end of the fixing strip 10 is larger than the size of the fixing groove 13, and the smaller end of the fixing strip 10 is smaller than the size of the fixing groove 13. When connecting the connecting block 8 and the driving block 9, the smaller end of the fixing strip 10 is inserted from one fixing groove 13 to the other fixing groove 13 and extends to the other side of the driving block 9 until the larger end of the fixing strip 10 is in contact with the outer wall of the driving block 9.

[0046] The fixing frame 15 is detachably sleeved on the outside of the fixing strip 10, and a positioning post 16 is slidably installed on one side of the fixing frame 15. A fixing hole adapted to the positioning post 16 is opened on one side of the fixing strip 10. After the small end of the fixing strip 10 passes through the two fixing grooves 13, the inner cavity of the fixing frame 15 passes through the small end of the fixing strip 10 until the middle of one end of the positioning post 16 and the middle of the opening end of the fixing hole are on the same horizontal line. Then, press the positioning post 16 to insert it into the inner wall of the fixing hole to limit the fixing strip 10 and prevent the fixing strip 10 from falling out of the inside of the limiting hole 14.

[0047] When one end of the positioning pin 16 is inserted into the inner cavity of the fixing hole, one end of the fixing frame 15 is attached to one side of the drive block 9, and at the same time, the large end of the fixing strip 10 is attached to the other side of the drive block 9. This can limit the fixing strip 10 and prevent the fixing strip 10 from shaking due to the vibration generated when the hydraulic cylinder is working, thus improving the stability of the fixing strip 10 after installation.

[0048] When the pressing mold 6 needs to be replaced, the limiting component is used to release the limiting component of the pressing mold 6. Then, the positioning pin 16 is pulled so that one end is completely pulled out of the inner cavity of the fixing hole. Then, the large end of the fixing strip 10 is pulled until the small end of the fixing strip 10 is completely pulled out of the inside of the limiting hole 14. Then, the pressing mold 6 is pulled up. At this time, the connecting block 8 is pulled out from the inside of the mounting slot. The disassembly of the pressing mold 6 is completed when the drive plate 12 is completely pulled out from the inside of the bearing frame 3 and moved to the top of the bearing frame 3. This reduces the time and effort required to replace the pressing mold 6 and improves the efficiency of replacing the pressing mold 6.

[0049] A through hole is provided on one side of the fixed frame 15. A guide tube is fixedly installed in the inner cavity of the through hole. The positioning post 16 is slidably installed in the inner cavity of the guide tube. The guide tube can limit the sliding trajectory of the positioning post 16, so that the positioning post 16 can only slide along its axial direction.

[0050] One end of the positioning post 16 passes through the guide tube and extends into the inner cavity of the fixing frame 15. The end of the positioning post 16 extending into the inner cavity of the fixing frame 15 is inclined. When the small end of the fixing strip 10 is inserted into the inner cavity of the fixing frame 15, the small end of the fixing strip 10 is in contact with the inclined side wall of the positioning post 16 and applies a movement away from itself to the positioning post 16. As the fixing frame 15 moves continuously, the inclined side wall of the positioning post 16 is in contact with the side wall of the fixing strip 10, so as to avoid affecting the normal movement of the fixing frame 15.

[0051] A top-compression spring is fixedly sleeved on the outer wall of the positioning post 16. The other end of the top-compression spring is fixedly connected to the inner wall of the guide tube. When the inclined side wall of the positioning post 16 is in contact with the outer wall of the fixing strip 10, the top-compression spring is compressed until the middle of the inclined end of the positioning post 16 is at the same horizontal line as the middle of the opening end of the fixing hole. The external force of the top-compression spring disappears and it can extend, so that the inclined end of the positioning post 16 can be inserted into the interior of the fixing hole, thus realizing the connection between the fixing frame 15 and the fixing strip 10.

[0052] Example 2

[0053] according to Figure 1-8 Further improvements made based on Example 1:

[0054] The limiting component includes a limiting frame 5 and a vertical block 4. The limiting frame 5 is fixedly sleeved on the outside of the pressing mold 6. When the pressing mold 6 is placed inside the bearing frame 3, the bottom of the limiting frame 5 and the top of the bearing frame 3 fit together. The pressing mold 6 can be supported by the mutual cooperation between the limiting frame 5 and the bearing frame 3.

[0055] Multiple through-posts 7 are fixedly installed at the bottom of the limiting frame 5. A through hole 19 adapted to the through-posts 7 is opened at the top of the bearing frame 3. When the bottom of the limiting frame 5 is attached to the top of the bearing frame 3, one end of the multiple through-posts 7 is inserted into the interior of the multiple through holes 19 at the same time, which can limit the installation position of the pressing mold 6 and prevent the pressing mold 6 from shifting when it is installed inside the bearing frame 3.

[0056] One side of the upright block 4 is fixedly connected to one side of the support frame 3, and both sides of the upright block 4 are provided with sliding grooves. Sliding blocks 22 are installed in the inner cavity of the two sliding grooves, so that the sliding blocks 22 can move back and forth in the vertical direction through the sliding grooves, which plays a role in limiting the sliding trajectory of the sliding blocks 22.

[0057] A U-shaped frame 21 is provided on the outside of the upright block 4. The two sides of the inner cavity of the U-shaped frame 21 are rotatably connected to the ends of two sliding blocks 22 that are far apart from each other through a rotating shaft. A pressure block 17 that is adapted to the U-shaped frame 21 is fixedly installed on the side of the limiting frame 5 near the upright block 4. When the bottom of the limiting frame 5 and the top of the bearing frame 3 are in contact, the end of the pressure block 17 that is far away from the limiting frame 5 extends to the top of the upright block 4. Then the U-shaped frame 21 is pushed. At this time, the inner wall of the U-shaped frame 21 rotates relative to the two sliding blocks 22 through the rotating shaft, and pushes the two sliding blocks 22 upwards until the inner wall of the U-shaped frame 21 that is far away from the rotating shaft is parallel to the top of the pressure block 17. Then the U-shaped frame 21 is pressed down until the inner wall of the U-shaped frame 21 that is far away from the rotating shaft is in contact with the top of the pressure block 17.

[0058] A column 20 is fixedly installed on the inner wall of the U-shaped frame 21 away from the pivot. The top of the pressure block 17 has an adapter hole that matches the column 20. When the inner wall of the U-shaped frame 21 away from the pivot is in contact with the top of the pressure block 17, the column 20 is inserted into the inner cavity of the adapter hole, thus realizing the connection between the inner wall of the U-shaped frame 21 and the pressure block 17.

[0059] A fixing band 23 is fixedly installed at one end of the sliding block 22 extending outside the slide groove. A limiting post 18 that limits the fixing band 23 is fixedly installed on the side of the upright block 4 near the slide groove. The outer wall of the fixing band 23 has an insertion hole that matches the limiting post 18. When one end of the upright post 20 is inserted into the matching hole, the free end of the fixing band 23 is pulled until the opening end of the insertion hole is at the same horizontal line as the middle of one end of the limiting post 18, thus limiting the free end of the fixing band 23. When the free end of the fixing band 23 moves down, the sliding block 22 is pulled down by the fixing band 23, and the inner wall of the U-shaped frame 21 presses the top of the pressure block 17, thereby applying a large downward pressure to the limiting frame 5, improving the tightness of the fit between the limiting frame 5 and the top of the bearing frame 3, preventing the pressing mold 6 from shaking when the red brick raw material is pressed inside the pressing mold 6, and improving the stability of the pressing mold 6.

[0060] When it is necessary to remove the pressing mold 6 from the inside of the support frame 3, pull up the free end of the fixing strap 23 to separate the insertion hole from the limiting post 18, and then push the sliding block 22 until the column 20 is pulled out from the adapter hole to separate the inner wall of the U-shaped frame 21 from the pressure block 17, so that the pressing mold 6 can be removed from the inside of the support frame 3.

[0061] The limiting post 18 is located directly below the slide groove. When the free end of the fixing band 23 is sleeved on the outside of the limiting post 18 through the through hole, the fixing band 23 applies a downward pressure perpendicular to the base plate 1 to the sliding block 22, thereby increasing the downward pressure applied by the fixing band 23 to the sliding block 22.

[0062] The fixing strap 23 is made of elastic fiber. When the free end of the fixing strap 23 is pulled to the insertion hole and sleeved on the outside of the limiting post 18, the deformation of the fixing strap 23 reaches its maximum value. The downward pressure applied to the sliding block 22 is always at its maximum value, which further improves the tightness of the fit between the top of the bearing frame 3 and the bottom of the limiting frame 5.

[0063] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
