[0033] The ejection component 6 can be used to eject all bricks in the lower mold 2 at the same time, completing synchronous demoulding and improving the demoulding efficiency. Then, the pushing component 7 is used to push the demoulding completed bricks to the next process, realizing the automatic collection and transportation of bricks, which not only reduces the labor intensity of workers, but also greatly improves the overall efficiency of the production line. At the same time, the cleaning component 8 will clean the lower mold 2 and the ejection component 6. Without affecting the production rhythm, the lower mold 2 and the ejection component 6 can be comprehensively cleaned, and the particles and dust generated during the demoulding process can be removed to ensure that there is no foreign matter in the lower mold 2, thereby avoiding the formation of defective products in subsequent production.

[0034] like Figure 2 , Figure 3 and Figure 4 As shown, the ejection assembly 6 includes a motor 601 arranged on the upper part of the base 1, the driving end of the motor 601 is fixedly connected to the worm 602, the upper surface of the base 1 is rotatably connected to the worm wheel 603, the worm wheel 603 is meshed with the worm 602, the top of the worm wheel 603 is fixedly connected to the turntable 604, and the edge of the turntable 604 is provided with a ring matrix of levers 605. The ejection assembly 6 also includes a one-way gear 606 rotatably connected to the upper surface of the base 1 through a damping shaft, the one-way gear 606 is meshed with the lever 605, and the top of the one-way gear 606 is fixedly connected to a protrusion 607, and the upper surface of the base 1 is slidably connected to a truss 608, and both ends of the bottom of the truss 608 are limited sliding The truss 608 is movably connected to the inside of the base 1, and the protrusion 607 is slidably connected to the inside of the truss 608. The inside of the truss 608 is hollow. The protrusion 607 will slide inside the truss 608 during the movement. The top of the truss 608 is hinged with an inclined rod 609, and the end of the inclined rod 609 away from the truss 608 is hinged with a connecting piece 610. The top of the connecting piece 610 is fixedly connected with a top plate 611. The connecting piece 610 connects all the top plates 611. The inclined rod 609 is hinged at the center of the lower surface of the connecting piece 610. The top plate 611 is spliced ​​by a rectangular plate and a cylinder. The top plate 611 is movably interspersed and arranged at the bottom end of the lower mold 2, and the rectangular plate structure of the top plate 611 extends into the casting groove of the lower mold 2.

[0035] After the mold is opened, the motor 601 is started. The motor 601 first drives the worm 602 to rotate clockwise, and the worm 602 drives the worm wheel 603 and the turntable 604 to rotate synchronously. The turntable 604 will mesh with the one-way gear 606 during the rotation, and then the lever 605 will drive the one-way gear 606 to rotate. The protrusion 607 will push the truss 608 to move during the rotation of the one-way gear 606. While the truss 608 moves, it will drive the inclined rod 609 to move obliquely upward. The top of the inclined rod 609 is a connecting piece 610 connected to all the top plates 611, and then the inclined rod 609 pushes the connecting piece 610 to move upward, which will push the top plate 611 upward to eject the brick from the lower mold 2. The lower mold 2 can produce multiple bricks at the same time and can demold them synchronously, which not only greatly improves the demolding efficiency and production efficiency, but also ensures that the bricks are not damaged during the demolding process.

[0036] like Figure 5 , Figure 6 and Figure 7 As shown, the pushing assembly 7 includes a vertical rod 701 rotatably connected to the surface of the base 1, and a one-way gear 2 702 is fixedly sleeved on the lower part of the outer surface of the vertical rod 701. The one-way gear 2 702 and the one-way gear 1 606 mentioned above are both a combination structure of a circular plate and a ratchet rod. The ratchet rod on the outer surface of the structure is subjected to unidirectional force, thereby ensuring unidirectional transmission. The one-way gear 2 702 is meshed with the shift rod 605. The top of the vertical rod 701 is fixedly connected to a short connecting rod 703, and the end of the short connecting rod 703 away from the vertical rod 701 is movably connected to a long connecting rod 704, and the other end of the long connecting rod 704 is hinged with a U-shaped rod 705, and the end of the U-shaped rod 705 is fixedly connected to a push plate 706. The length is half of the length of the long connecting rod 704, ensuring that the short connecting rod 703 can drive the long connecting rod 704 to rotate during the rotation around the vertical rod 701. The length of the long connecting rod 704 is the same as the width of the lower mold 2. The pushing distance of the short connecting rod 703 after one rotation is the length of the long connecting rod 704, thereby ensuring that the bricks are pushed down from the lower mold 2. The length of the push plate 706 is equal to the length of the lower mold 2, which is convenient for synchronously pushing all bricks during the pushing process. Both ends of the push plate 706 are fixedly connected with sliders 707, and a slide groove 708 is provided in the middle of the bracket 3. The slider 707 slides inside the slide groove 708 to limit and support the push plate 706.

[0037] The motor 601 drives the worm 602 to rotate counterclockwise, and the worm 602 drives the worm wheel 603 and the turntable 604 to rotate synchronously. At this time, the turntable 604 will mesh with the one-way gear 2 702 during the rotation, but will be in a sliding connection with the one-way gear 1 606, and then the lever 605 will drive the one-way gear 2 702 to rotate, and the one-way gear 2 702 will drive the short connecting rod 703 to rotate through the vertical rod 701. During the rotation of the short connecting rod 703, the long connecting rod 704 will be driven to reciprocate, and the other end of the long connecting rod 704 will push the U-shaped rod 705 to reciprocate. Since both ends of the push plate 706 are limited and slidable in the bracket 3, the push plate 706 will move with the U-shaped rod 705 to push away the bricks that have been ejected, thereby achieving the purpose of automatic collection and transportation, and realizing the automatic collection and transportation of bricks, which not only reduces the labor intensity of workers, but also greatly improves the overall efficiency of the production line.

[0038] like Figures 6 to 8 As shown, the cleaning assembly 8 includes an axle rod 801 movably inserted in the middle of the U-shaped rod 705, the axle rod 801 is spliced ​​by a round rod and a square rod, the round rod passes through the U-shaped rod 705, both ends of the axle rod 801 pass through the U-shaped rod 705, the outer surface of the axle rod 801 is movably sleeved with a sleeve 802, the sleeve 802 is sleeved on the outer surface of the square rod, and the outer surface of the sleeve 802 is distributed with a brush plate 804 in an annular matrix to ensure that the lower mold 2 can be continuously cleaned during the rotation of the sleeve 802. The cleaning assembly 8 also includes A spur gear 803 is fixedly connected to the end of the shaft 801, a rack 805 is arranged on the inner side of the middle part of the bracket 3, the spur gear 803 is meshed with the rack 805, a round rod 806 is fixedly connected to the end of the sleeve 802, an inclined groove 807 is provided on the inner wall of the U-shaped rod 705, and the round rod 806 slides inside the inclined groove 807, and the inner walls on both sides of the U-shaped rod 705 are provided with inclined grooves 807, and the inclined grooves 807 on both sides are in opposite directions, so as to ensure that the round rod 806 can do reciprocating motion during the sliding process in the inclined groove 807;

[0039] During the movement, the spur gear 803 will mesh with the rack 805, which will drive the shaft 801 to rotate. The rotation of the shaft 801 will drive the sleeve 802 to rotate synchronously. The cleaning brush distributed in a ring matrix on the outer surface of the sleeve 802 will rotate synchronously to clean the particles and dust retained on the surface of the lower mold 2 and the top plate 611. During the rotation of the sleeve 802, the round rod 806 will slide in the inclined groove 807, which will promote the sleeve 802 and the shaft 801 to undergo a lateral relative displacement, so that the brush plate 804 performs a linear reciprocating motion while rotating and cleaning, thereby improving the cleaning effect. Without affecting the production rhythm, the lower mold 2 and the ejection assembly 6 can be fully cleaned, and the particles and dust generated during the demoulding process can be removed to ensure that there are no foreign objects in the lower mold 2, thereby avoiding the formation of defective products in subsequent production.

[0040] The technical solution provided by the present invention is that when the device is in use, the upper mold 5 is pushed down and molded with the lower mold 2 by the hydraulic driving component 4. The hydraulic driving component 4, with its stable and reliable performance, accurately controls the downward movement of the upper mold 5 and the mold closing process of the lower mold 2, laying a solid foundation for the subsequent raw material pouring. The raw material is evenly injected into the mold cavity under high pressure, and gradually solidifies and forms with the passage of time, showing the texture and strength that the brick should have. After forming, the hydraulic driving component 4 pulls the upper mold 5 up to open the mold, and the ejection component 6 can be used to eject all the bricks in the lower mold 2 at the same time to complete the synchronous demoulding. This step not only greatly improves the demoulding efficiency, but also ensures that the bricks are not damaged during the demoulding process, maintaining a perfect appearance and dimensional accuracy. Then, the demoulding-completed bricks are pushed to the next process by the pushing component 7. The whole process is smooth and does not require manual intervention, realizing the automatic collection and transportation of bricks, which not only reduces the labor intensity of workers, but also greatly improves the overall efficiency of the production line. At the same time, the cleaning component 8 will clean the lower mold 2 and the ejection component 6. The lower mold 2 and the ejector assembly 6 can be cleaned without affecting the production rhythm, and the particles and dust generated during the demoulding process can be removed to ensure that there is no foreign matter in the lower mold 2, so as to avoid the formation of defective products in the subsequent production. The specific operation is as follows: after the mold is opened, the motor 601 is started, and the motor 601 first drives the worm 602 to rotate clockwise, and the worm 602 drives the worm wheel 603 and the turntable 604 to rotate synchronously. The turntable 604 will mesh with the one-way gear 1 606 during the rotation, and then the lever 605 will shift The one-way gear 606 rotates, and the protrusion 607 pushes the truss 608 to move as the one-way gear 606 rotates. The movement of the truss 608 drives the inclined rod 609 to move obliquely upward. The top of the inclined rod 609 is a connecting piece 610 connected to all the top plates 611. Then the inclined rod 609 pushes the connecting piece 610 to move upward, which pushes the top plate 611 to move upward, and finally pushes the top plate 611 out of the mold together with the bricks. The lower mold 2 can produce multiple bricks at the same time and can demould them synchronously, thereby improving the demoulding efficiency and production efficiency.

[0041] After the brick is ejected from the lower mold 2, the motor 601 drives the worm 602 to rotate counterclockwise, and the worm 602 drives the worm wheel 603 and the turntable 604 to rotate synchronously. At this time, the turntable 604 will mesh with the one-way gear 2 702 during the rotation, but will be in a sliding connection with the one-way gear 1 606, and then the lever 605 will drive the one-way gear 2 702 to rotate, and the one-way gear 2 702 will drive the short connecting rod 703 to rotate through the vertical rod 701. During the rotation of the short connecting rod 703, the long connecting rod 704 will be driven to reciprocate, and the other end of the long connecting rod 704 will push the U-shaped rod 705 to reciprocate. Since both ends of the push plate 706 are limited and slidable in the bracket 3, the push plate 706 will move with the U-shaped rod 705 to push away the ejected bricks, thereby achieving the purpose of automatic collection and transportation. , the cleaning component 8 runs accordingly, and the spur gear 803 will mesh with the rack 805 during the movement, thereby driving the shaft 801 to rotate, and the rotation of the shaft 801 will drive the sleeve 802 to rotate synchronously, and the cleaning brush distributed in a ring matrix on the outer surface of the sleeve 802 will rotate synchronously to clean the particles and dust retained on the surface of the lower mold 2 and the top plate 611. During the rotation of the sleeve 802, the round rod 806 will be driven to slide in the inclined groove 807, and then the sleeve 802 and the shaft 801 will be pushed to have a lateral relative displacement, so that the brush plate 804 performs a linear reciprocating motion while rotating and cleaning. This composite motion mode greatly enhances the cleaning effect, ensures the cleanliness of the lower mold 2 and the ejection component 6, removes the particles and dust generated during the demoulding process, ensures that there is no foreign matter in the lower mold 2, and avoids the formation of defective products in subsequent production.
