[0003] The existing patent (Announcement No.: CN216067954U) discloses a concrete brick extrusion molding device, which relates to the field of construction engineering technology. A concrete brick extrusion molding device includes an assembly box with a hole at the bottom, a baffle plate movably installed at the bottom of the assembly box, and an assembly mold fixedly installed inside the assembly box. In the process of implementing this solution, it was found that the following problems exist in the prior art and have not been well solved: when the device is used, the material is fed into the assembly mold through a feed pipe. When the feed pipe falls into the assembly mold, bubbles are easily generated inside the material. At this time, when the material is directly extruded and molded through a press plate, bubbles are easily generated inside the concrete brick. Utility Model Content

[0004] In order to improve the problem that the above-mentioned device feeds materials into the assembly mold through a feeding pipe when in use, bubbles are easily generated inside the material when the feeding pipe falls into the assembly mold. At this time, when the material is directly extruded and molded through a pressing plate, bubbles are easily generated inside the concrete brick. The present application provides a high-strength recycled concrete brick extrusion molding equipment.

[0005] The present application provides a high-strength recycled concrete brick extrusion molding device, which adopts the following technical solution:

[0006] A high-strength recycled concrete brick extrusion molding equipment includes a base, a support frame is fixedly arranged on the top of the base, a first cylinder is fixedly inserted on the top of the support frame, a pressing plate is fixedly arranged on the protruding end of the first cylinder, the top of the base is recessed downward to form a movable groove, a mold is movably arranged in the movable groove, guide rods are fixedly arranged at both ends of the mold, and slide rods are fixedly arranged at both ends of the top surface of the pressing plate, the guide rods are located inside the slide rods and slidably cooperate with the inner wall of the slide rod.

[0007] Through the above technical solution, the concrete material is first put into the mold, and then the pressure plate is pushed downward by the first cylinder. As the pressure plate moves downward, the slide rod is driven to move synchronously. At this time, the guide rod slides along the inner wall of the slide rod and causes the mold to shake left and right, thereby causing the material in the mold to shake and reducing the bubbles generated inside the material.

[0008] Optionally, in the above-mentioned high-strength recycled concrete brick extrusion molding equipment, a feeding pipe is fixedly and obliquely arranged on the top of the base, and the lower end of the feeding pipe is in contact with the top of the mold.

[0011] Through the above technical solution, after the concrete brick is extruded and formed, the push plate is pushed upward by the second cylinder, thereby pushing the concrete brick out of the mold.

[0012] Optionally, in the above-mentioned high-strength recycled concrete brick extrusion molding equipment, a through hole is penetrated through the inner bottom of the movable groove, and the second cylinder is slidably matched with the inner wall of the through hole.

[0013] With the above technical solution, the second cylinder can move along with the mold through the through hole when the mold moves.

[0014] Optionally, in the above-mentioned high-strength recycled concrete brick extrusion forming equipment, two limit blocks are symmetrically arranged on the outer wall of the second cylinder, and limit grooves corresponding to the limit blocks are symmetrically opened on the inner wall of the through hole, and the two limit blocks are respectively located in the two limit grooves.

[0017] Through the above technical solution, the guide rod is conveniently fixed on the mold through two fixing blocks. When the slide slot rod moves, the guide rod moves along the inner wall of the slide slot rod, and the mold moves synchronously with the guide rod.

[0018] Optionally, in the above-mentioned high-strength recycled concrete brick extrusion forming equipment, the slide rod includes a U-shaped plate, one end of the U-shaped plate is fixedly connected to the top of the pressing plate, and the other end of the U-shaped plate is fixedly connected to a vertical plate, and the vertical plate is provided with vertical grooves and wavy grooves in sequence from top to bottom, and the vertical grooves are connected to the wavy grooves.

[0019] Through the above technical solution, the vertical plate and the pressure plate are conveniently connected together through the U-shaped plate, so that the vertical plate can move synchronously with the pressure plate when it moves. When the vertical plate moves, the guide rod slides along the inner wall of the wavy groove, thereby causing the material in the mold to shake.

[0020] In summary, the present application includes at least one of the following beneficial effects:

[0021] When the pressing plate moves downward, it drives the slide rod to move synchronously. At this time, the guide rod slides along the inner wall of the slide rod and causes the mold to shake left and right, thereby causing the material in the mold to shake and reduce the bubbles generated inside the material. Therefore, the device can reduce the bubbles generated in the concrete bricks when extruding the concrete bricks;

[0022] After the concrete brick is extruded into shape, the first cylinder drives the pressing plate, U-shaped plate and vertical plate to move up, and then the guide rod slides along the inner wall of the wavy groove to cause the mold to shake, and then the second cylinder pushes the push plate to move up to push the concrete brick out of the mold, so that the concrete brick is more convenient to demold.

[0028] The following is combined with Figure 1-4 This application is described in further detail.

[0029] Please refer to the attached figure in the instruction manual Figure 1-4The present application provides an embodiment: a high-strength recycled concrete brick extrusion molding equipment, including a base 1, a support frame 2 is fixedly arranged on the top of the base 1, and a first cylinder 3 is fixedly inserted on the top of the support frame 2, and the first cylinder 3 is conveniently assembled through the support frame 2; a pressing plate 4 is fixedly arranged on the protruding end of the first cylinder 3, and a movable groove 5 is recessed downward on the top of the base 1, and a mold 6 is movably arranged in the movable groove 5, and the pressing plate 4 is pushed downward by the first cylinder 3. As the pressing plate 4 moves downward and is inserted into the mold 6, the concrete material in the mold 6 is extruded and molded by the pressing plate 4.

[0030] A second cylinder 61 is fixedly inserted at the bottom of the mold 6, and the protruding end of the second cylinder 61 is inserted into the mold 6 and fixedly provided with a push plate 62. The push plate 62 is movably arranged in the mold 6. When the concrete brick is extruded and formed, the push plate 62 is pushed upward by the second cylinder 61, thereby pushing the concrete brick out of the mold 6, making it easier for the operator to take the concrete brick.

[0031] A through hole 51 is formed through the inner bottom of the movable groove 5 , and the second cylinder 61 is slidably matched with the inner wall of the through hole 51 , so that the second cylinder 61 can move along with the mold 6 when the mold 6 moves.

[0032] Two limit blocks 63 are symmetrically arranged on the outer wall of the second cylinder 61, and limit grooves 52 corresponding to the limit blocks 63 are symmetrically opened on the inner wall of the through hole 51. The two limit blocks 63 are respectively located in the two limit grooves 52. The two limit grooves 52 cooperate with the two limit blocks 63 to increase the stability of the second cylinder 61 during movement, while reducing the possibility of separation of the second cylinder 61 and the through hole 51.

[0033] A feeding pipe 11 is fixedly arranged at an angle on the top of the base 1 , and the lower end of the feeding pipe 11 is in contact with the top of the mold 6 . The feeding pipe 11 is convenient for an operator to feed concrete materials into the mold 6 for extrusion molding.

[0034] Guide rods 7 are fixedly provided at both ends of the mold 6, and slide rods 8 are fixedly provided at both ends of the top surface of the pressure plate 4. The guide rod 7 is a round rod structure, and fixed blocks 71 are fixedly sleeved at both ends of the guide rod 7. The fixed blocks 71 are fixedly connected to the outer wall of the mold 6. The guide rod 7 is conveniently fixed to the mold 6 through the two fixed blocks 71. When the slide rod 8 moves, the guide rod 7 moves along the inner wall of the slide rod 8. At this time, the mold 6 moves synchronously with the guide rod 7, and causes the material in the mold 6 to shake, and reduces the bubbles generated inside the material.

[0035] The guide rod 7 is located inside the slide rod 8 and slidably cooperates with the inner wall of the slide rod 8. The slide rod 8 includes a U-shaped plate 81, one end of the U-shaped plate 81 is fixedly connected to the top of the pressing plate 4, and the other end of the U-shaped plate 81 is fixedly connected to a vertical plate 82. The vertical plate 82 is provided with vertical grooves 83 and wavy grooves 84 from top to bottom, and the vertical grooves 83 are connected to the wavy grooves 84. The U-shaped plate 81 is used to connect the vertical plate 82 and the pressing plate 4 together, so that when the pressing plate 4 moves, the vertical plate 82 can move synchronously with it. When the vertical plate 82 moves, the guide rod 7 slides along the inner wall of the wavy groove 84, thereby causing the material in the mold 6 to shake. When the guide rod 7 slides along the inner wall of the vertical groove 83, the mold 6 remains stationary, and at this time, the material is conveniently extruded and formed through the pressing plate 4;

[0036] After the concrete brick is extruded and formed, the first cylinder 3 drives the pressing plate 4, the U-shaped plate 81 and the vertical plate 82 to move upward, and then the guide rod 7 slides along the inner wall of the wavy groove 84 to cause the mold 6 to shake, thereby increasing the demolding effect of the concrete brick, and then the second cylinder 61 pushes the push plate 62 to move upward, thereby pushing the concrete brick out of the mold 6, making it easier for the operator to take the concrete brick.

[0037] Working principle: When using the high-strength recycled concrete brick extrusion molding equipment, first put the concrete material into the mold 6, and then push the pressing plate 4 downward through the first cylinder 3. As the pressing plate 4 moves downward, the slide rod 8 is driven to move synchronously. At this time, the guide rod 7 slides along the inner wall of the slide rod 8 and causes the mold 6 to shake left and right, thereby causing the material in the mold 6 to shake and reduce the bubbles generated inside the material. Then, the concrete brick is extruded into shape through the cooperation of the pressing plate 4 and the mold 6. Therefore, the device can reduce the bubbles in the concrete brick when extruding the concrete brick.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
