Description

Technical Field

[0001] This invention relates to the field of energy-saving building materials production technology, specifically to a molding die for processing energy-saving building materials for water conservancy projects.

[0002] Background Technology Fly ash bricks are a type of energy-saving building material. In water conservancy projects, fly ash bricks are often used as admixtures in cement and mortar to improve the impermeability, durability and crack resistance of concrete. They are also used to construct drainage systems.

[0003] Existing fly ash brick molding molds often contain air in the gaps of the raw materials during the processing of fly ash bricks, which is difficult to fully expel. This leads to the formation of air holes inside the pressed fly ash bricks, thus affecting their molding quality. Although some molds are equipped with venting structures, fly ash brick raw materials can easily enter the venting structures, causing blockages and affecting the subsequent venting effect. Furthermore, this results in unevenness on the top of the molded fly ash bricks, which in turn affects their later use performance. Summary of the Invention

The combined exhaust mechanism includes multiple exhaust channels opened inside the pressure block, an elastic component disposed between the pressure block and the linkage block, and multiple integrated exhaust anti-blocking components installed at the bottom of the linkage block; The feeding mechanism, which is installed on top of the base, is used to feed brick-making raw materials into the mold cavity; The demolding mechanism, which is installed inside the base and connected to the mold cavity, is used to eject the formed fly ash bricks.

[0006] Furthermore, the lifting assembly includes four columns mounted on the top of the base, a fixed seat mounted on the top of the four columns, and a first hydraulic cylinder mounted inside the fixed seat; The extended end of the first hydraulic cylinder is equipped with a slide block, which is slidably sleeved on the outside of the four columns, and the multiple linkage blocks are all fixedly connected to the bottom of the slide block.

[0007] Furthermore, the elastic component includes a plurality of first storage slots formed inside the linkage block, a telescopic rod fixed inside the first storage slots, and a first spring sleeved outside the telescopic rod.

[0008] Furthermore, the exhaust anti-blocking integrated component is located above the exhaust channel, and the exhaust anti-blocking integrated component includes a second storage groove opened at the bottom of the linkage block, a linkage rod fixed inside the second storage groove, and a flat block fixed at the bottom end of the linkage rod. The outer wall of the flat block is adapted to the inner wall of the exhaust channel, and multiple linked exhaust holes are opened inside the flat block.

[0009] Furthermore, the exhaust anti-blocking integrated assembly also includes a support frame that is slidably sleeved on the outside of the linkage rod, a plurality of top rods fixed to the bottom of the support frame, and a second spring sleeved on the outside of the linkage rod; The outer diameter of the support frame is larger than the inner diameter of the exhaust channel, but smaller than the inner diameter of the second storage slot. Each of the aforementioned push rods corresponds to a plurality of linked exhaust holes, and the push rods and the linked exhaust holes are of the same size. The top end of the second spring is fixedly connected to the inner wall of the top of the second storage slot, and the bottom end of the second spring is fixedly connected to the top of the support frame.

[0010] Furthermore, the feeding mechanism includes a material frame disposed on the top of the base, a mixing component installed inside the material frame, and an adjustment component for driving the material frame to move; The mixing assembly includes multiple drive shafts rotatably connected inside the material frame and multiple stirring blades installed outside the drive shafts.

After the fly ash bricks are pressed and formed, the residual raw material residue inside the linkage vent hole can be automatically removed, preventing the linkage vent hole from becoming blocked after multiple uses of the flat block, and ensuring the venting effect of the fly ash bricks during each pressing and forming process.

[0017] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0018] Example: Please refer to Figure 1 - Figure 7 A molding die for processing energy-saving building materials for water conservancy projects, including a base 1, and further comprising: The molding mechanism includes multiple mold cavities 2 opened on the top of the base 1, pressure blocks 3 respectively disposed above the multiple mold cavities 2, linkage blocks 4 respectively disposed above the multiple pressure blocks 3, and a lifting assembly for driving the multiple linkage blocks 4 to rise and fall synchronously. The pressure blocks 3 are adapted to the mold cavities 2. The lifting assembly includes four columns 6 installed on the top of the base 1, fixed seats 7 installed on the top of the four columns 6, and a first hydraulic cylinder 8 installed inside the fixed seat 7. The extended end of the first hydraulic cylinder 8 is equipped with a slide 9, which is slidably sleeved on the outside of the four columns 6. The multiple linkage blocks 4 are all fixedly connected to the bottom of the slide 9. After the fly ash brick raw material is put into the mold cavity 2, the first hydraulic cylinder 8 is extended by controlling it to drive the slide 9 to move downward along the outer wall of the column 6. The linkage block 4 and the pressure block 3 move downward accordingly. The pressure block 3 enters the mold cavity 2 to initially compress the fly ash brick raw material. When the linkage block 4 and the pressure block 3 come into contact, the fly ash brick raw material is gradually pressed into the mold cavity 2 to obtain the formed fly ash brick. After the fly ash bricks are pressed and formed, the first hydraulic cylinder 8 is controlled to drive the slide 9 to move upward, and the linkage block 4 and the pressing block 3 move upward accordingly, so that the pressing block 3 completely disengages from the mold cavity 2 and resets.

[0019] The combined exhaust mechanism includes multiple exhaust channels 5 formed inside the pressure block 3, an elastic component disposed between the pressure block 3 and the linkage block 4, and multiple integrated exhaust anti-blocking components installed at the bottom of the linkage block 4. The elastic component includes multiple first receiving slots 10 formed inside the linkage block 4, a telescopic rod 11 fixed inside the first receiving slot 10, and a first spring 12 sleeved outside the telescopic rod 11. After the pressure block 3 abuts against the linkage block 4, the telescopic rod 11 and the first spring 12 retract into the first receiving slot 10. The extended end of the telescopic rod 11 is fixed to the top of the pressure block 3. The top end of the first spring 12 is fixed to the inner wall of the top of the first receiving slot 10, and the bottom end of the first spring 12 is fixed to the top of the pressure block 3. The integrated exhaust anti-blocking component is located above the exhaust channels 5. The integrated exhaust anti-blocking component includes a second receiving slot 13 formed at the bottom of the linkage block 4, a linkage rod 14 fixed inside the second receiving slot 13, and a flat block 15 fixed to the bottom end of the linkage rod 14. After the moving block 4 abuts, the support frame 27 and the second spring 17 are located inside the second receiving groove 13. An extended air groove can be opened at the top of the second receiving groove 13. After the pressing block 3 abuts with the linkage block 4, the second receiving groove 13 connects with the exhaust channel 5 to discharge the small amount of air remaining during pressing. The outer wall of the flat block 15 is adapted to the inner wall of the exhaust channel 5. Multiple linkage exhaust holes 16 are opened inside the flat block 15. The exhaust anti-blocking integrated assembly also includes a sliding sleeve on the outside of the linkage rod 14. The support frame 27, multiple top rods 28 fixed to the bottom of the support frame 27, and a second spring 17 sleeved on the outside of the linkage rod 14; the outer diameter of the support frame 27 is larger than the inner diameter of the exhaust channel 5 and smaller than the inner diameter of the second storage groove 13; the multiple top rods 28 correspond to multiple linkage exhaust holes 16 respectively, and the top rods 28 and linkage exhaust holes 16 are the same size; the top end of the second spring 17 is fixed to the inner wall of the top of the second storage groove 13, and the bottom end of the second spring 17 is fixed to the top of the support frame 27; When the pressure block 3 moves down into the mold cavity 2 and contacts the fly ash brick material, as the linkage block 4 continues to move down, the first spring 12 is gradually compressed, and the elastic force of the first spring 12 gradually increases, driving the pressure block 3 to gradually press the fly ash brick material. During this process, the air inside the fly ash brick material is first discharged through the exhaust channel 5. When the flat block 15 enters the exhaust channel 5, the support frame 27 abuts against the top of the pressure block 3, and the support frame 27 and the top rod 28 stop moving downward. The second spring 17 is gradually compressed, causing the top rod 28 to separate from the linkage exhaust hole 16. The air inside the exhaust channel 5 begins to be discharged through the linkage exhaust hole 16. After the pressure block 3 abuts against the linkage block 4, the flat block 15 moves down along the inner wall of the exhaust channel 5 to the lower edge of the exhaust channel 5. The lower edge of the leveling block 15 is at the same horizontal level as the lower edge of the exhaust channel 5, thereby squeezing out the raw material that has entered the exhaust channel 5, making the top of the fly ash brick flat. The linkage block 4 drives the pressure block 3 to continue to move downward, compacting the fly ash brick raw material. After the fly ash brick is pressed into shape, the linkage block 4 and the pressure block 3 are driven to move upward and reset. During this process, the linkage block 4 gradually separates from the pressure block 3, and the leveling block 15 gradually detaches from the exhaust channel 5. After the leveling block 15 moves upward above the pressure block 3, the rebound force of the second spring 17 drives the top rods 28 at the bottom of the support frame 27 to insert into the linkage exhaust hole 16, removing the raw material residue remaining in the linkage exhaust hole 16, and preventing the linkage exhaust hole 16 inside the leveling block 15 from becoming blocked after multiple uses.

[0020] A feeding mechanism, installed on top of the base 1, is used to feed brick-making raw materials into the mold cavity 2. The feeding mechanism includes a material frame 18 set on top of the base 1, a mixing assembly 19 installed inside the material frame 18, and an adjusting assembly for driving the material frame 18 to move. The mixing assembly 19 includes multiple drive shafts rotatably connected inside the material frame 18 and multiple stirring blades installed outside the drive shafts. The stirring blades can also prevent the fly ash brick raw materials inside the material frame 18 from clumping. One end of the drive shaft is connected to a first motor, which is installed on the outer wall of the material frame 18. The adjusting assembly includes a lead screw 20 rotatably connected to the outer wall of the base 1, a connecting block 21 threadedly connected to the outside of the lead screw 20, and a second motor 22 connected to one end of the lead screw 20. The second motor 22 is installed on the outer wall of the base 1. The connecting block 21 is fixedly connected to the material frame 18. By controlling the second motor 22 to drive the lead screw 20 to rotate clockwise, the material frame 18 is moved to the right to the top of each mold cavity 2 via the connecting block 21. By controlling the first motor to drive the transmission shaft and its external stirring blades to rotate, the fly ash brick raw material inside the material frame 18 is evenly introduced into the mold cavity 2. After the material is added, the second motor 22 is controlled to drive the lead screw 20 to rotate counterclockwise, causing the material frame 18 to move to the left and reset. During this process, the fly ash brick raw material that exceeds the top of the mold cavity 2 is scraped off, so that the material is added evenly inside each mold cavity 2.

[0021] A demolding mechanism is installed inside the base 1 and connected to the mold cavity 2. It is used to eject the formed fly ash bricks. The demolding mechanism includes a second hydraulic cylinder 23 installed inside the base 1, a support plate 24 fixed to the extended end of the second hydraulic cylinder 23, and a plurality of top blocks 25 fixed to the top of the support plate 24. The top of the top blocks 25 extends into the interior of the mold cavity 2. Four fixing rods 26 are installed inside the base 1. The support plate 24 is slidably sleeved on the outside of the four support plates 24. A belt conveyor can be installed on the right side of the base 1. After the fly ash bricks are pressed and formed, the second hydraulic cylinder 23 is extended, driving the support plate 24 to move upward along the outside of the fixed rod 26. The top block 25 then moves upward along the inner wall of the mold cavity 2, bringing the top of the fly ash bricks inside the mold cavity 2, with the upper edge of the top block 25 at the same horizontal height as the upper edge of the base 1. Then, the material frame 18 is driven to move to the right to the top of the mold cavity 2. During this process, the fly ash bricks on the top of the top block 25 are pushed to the right by the right side of the material frame 18 and conveyed to the top of the belt conveyor along the top of the base 1. The formed fly ash bricks are then conveyed away by the belt conveyor. Then, the second hydraulic cylinder 23 is controlled to drive the support plate 24 and the top block 25 on its top to move down and reset, so that the fly ash brick raw materials inside the material frame 18 can be put back into the mold cavity 2.

[0022] Working principle: During use, the second motor 22 drives the lead screw 20 to rotate clockwise, which in turn moves the material frame 18 to the right to the top of each mold cavity 2 via the connecting block 21. The first motor drives the transmission shaft and its external stirring blades to rotate, evenly introducing the fly ash brick material inside the material frame 18 into the mold cavity 2. After feeding, the second motor 22 drives the lead screw 20 to rotate counterclockwise, moving the material frame 18 to the left to reset. During this process, any fly ash brick material exceeding the top of the mold cavity 2 is scraped off, ensuring even feeding in each mold cavity 2. The first hydraulic cylinder 8 extends, causing the slide 9 to move downwards along the outer wall of the column 6. The linkage block 4 and the pressure block 3 move downwards accordingly, with the pressure block 3 moving into the mold cavity 2 to contact the fly ash brick material. When the fly ash brick raw material comes into contact, as the linkage block 4 continues to move downward, the first spring 12 is gradually compressed, and the elastic force of the first spring 12 gradually increases, driving the pressure block 3 to gradually press the fly ash brick raw material. During this process, the air inside the fly ash brick raw material is first discharged through the exhaust channel 5. When the flat block 15 enters the exhaust channel 5, the support frame 27 abuts against the top of the pressure block 3, and the support frame 27 and the top rod 28 stop moving downward. The second spring 17 is gradually compressed, causing the top rod 28 to separate from the linkage exhaust hole 16. The air inside the exhaust channel 5 begins to be discharged through the linkage exhaust hole 16. After the pressure block 3 abuts against the linkage block 4, the flat block 15 moves down along the inner wall of the exhaust channel 5 to the lower edge of the exhaust channel 5. That is to say, the flat block 15... The lower edge of the flattening block 15 is at the same level as the lower edge of the exhaust channel 5, thus squeezing out the raw material entering the exhaust channel 5 and flattening the top of the fly ash brick. The linkage block 4 drives the pressure block 3 to continue moving downward, compacting the fly ash brick raw material. After the fly ash brick is pressed into shape, the linkage block 4 and the pressure block 3 are driven to move upward and reset. During this process, the linkage block 4 gradually separates from the pressure block 3, and the flattening block 15 gradually detaches from the exhaust channel 5. After the flattening block 15 moves upward above the pressure block 3, the rebound force of the second spring 17 drives the top rods 28 at the bottom of the support frame 27 to insert into the linkage exhaust hole 16, removing the raw material residue remaining in the linkage exhaust hole 16 and preventing the linkage exhaust hole 16 inside the flattening block 15 from becoming blocked after repeated use. The problem is that the second hydraulic cylinder 23 is then extended, causing the support plate 24 to move upward along the outside of the fixed rod 26. The top block 25 then moves upward along the inner wall of the mold cavity 2, bringing the top of the fly ash brick inside the mold cavity 2 to the same horizontal level as the top edge of the base 1. Then, the material frame 18 is driven to move to the right to the top of the mold cavity 2. During this process, the fly ash brick on the top of the top block 25 is pushed to the right by the right side of the material frame 18 and conveyed to the top of the belt conveyor along the top of the base 1. The formed fly ash brick is then conveyed away by the belt conveyor. Then, the second hydraulic cylinder 23 is controlled to move the support plate 24 and the top block 25 on its top down to reset, so that the fly ash brick raw material inside the material frame 18 can be put back into the mold cavity 2.
