Description

Technical Field

[0001] This application relates to the field of irregular brick molds, and more particularly to an irregular brick abrasive. Background Technology

[0002] Irregularly shaped brick molds are used to manufacture bricks with special shapes. They employ a special design that results in bricks with unique shapes and textures.

[0003] In related technologies, Chinese patent CN221872438U discloses a rectangular master mold for irregularly shaped bricks, including a base, a support frame fixedly connected to one side of the base, a lifting mechanism fixedly connected to one side of the support frame, a master mold fixedly connected to one side of the lifting mechanism, four support legs fixedly connected to the bottom of the base, a power supply provided on one side of the base, an installation groove provided on one side of the base, a lower mold fixedly connected to one side of the installation groove, and a vibrator fixedly connected to one side of the lower mold. The advantages of this invention are: when the device is working, concrete is first poured into the lower mold, the master mold is lowered and shaped by the lifting mechanism, and alignment is ensured by guide columns and guide holes, ensuring accurate placement of the bricks and achieving pressing and shaping of the concrete.

[0004] However, the structure of the master mold is fixed, so it can only produce one type of irregular brick. If other shapes of irregular bricks are needed, the entire base and support frame structure needs to be replaced, which is inconvenient to operate and therefore needs to be improved. Utility Model Content

[0005] To address the inconvenience caused by replacing the entire base and other structures when producing irregularly shaped bricks, this application provides a mold for irregularly shaped bricks.

[0006] The technical solution for the irregularly shaped brick mold provided in this application is as follows:

[0007] A special-shaped brick grinding tool includes a mounting base, a lower mold mounted on the mounting base, a support frame fixed on the mounting base, a cylinder mounted on the support frame, a mounting block fixed to the output end of the cylinder, the cylinder driving the mounting block to move up and down, a female mold connected to the mounting block, the female mold being located directly above the lower mold, a mounting hole being formed on the top wall of the female mold, the mounting block being inserted into the mounting hole, a limit hole being formed on the side wall of the mounting block, a limit block being provided in the limit hole, the limit block being connected to the inner wall of the limit hole via a limit spring, a connecting rope being connected to the limit block, the connecting rope extending out of the mounting block, a positioning hole being provided on the inner wall of the mounting hole, the limit block being inserted into the positioning hole.

[0008] By adopting the above technical solution, during use, concrete is first poured into the lower mold, then the cylinder is activated to drive the mounting block, carrying the mother mold, downwards until the mother mold covers the lower mold, thus pressing and shaping the clay in the lower mold. This enables the preparation of irregularly shaped bricks. When different shaped bricks need to be prepared, the connecting rope is pulled to pull the limiting block into the limiting hole for storage, ensuring that the side wall of the mounting block has no protrusions, making it easy to remove the mother mold from the mounting block. Next, the mounting hole on the new mother mold is aligned with the mounting block, and the limiting block is manually pressed so that the mounting block can be smoothly inserted into the mounting hole. When the limiting block in the mounting hole reaches the positioning hole, the connecting spring returns to its original deformation, moving the limiting block into the positioning hole. At this time, the side wall of the limiting block abuts against the inner wall of the positioning hole, providing a restraining effect and fixing the mother mold and mounting block together. This allows for the replacement of the mother mold shape to adapt to the production of irregularly shaped bricks of different shapes without changing the entire structure of the mounting base, making the operation convenient.

[0009] Optionally, the limiting block has a guide surface on its side wall away from the central axis of the mounting block, and the bottom end of the guide surface is inclined toward the central axis of the mounting block.

[0010] By adopting the above technical solution, during installation, the mounting hole on the female mold is aligned with the mounting block, and the female mold is moved towards the mounting block. When the limiting block reaches the mounting hole, the guide surface abuts against the inner wall of the mounting hole. The mold continues to move, and the guide surface acts as a guide, causing the inner wall of the mounting hole to slide on the guide surface. This gradually compresses the connecting spring with the limiting block until the limiting block is housed in the limiting hole, facilitating the insertion of the mounting block into the mounting hole. When the limiting block aligns with the positioning hole, the side wall of the limiting block loses its restraint, the connecting spring returns to its original deformation, and pushes the limiting block into the positioning hole, preventing the mounting block from being pulled out of the mounting hole. This achieves the installation of the female mold on the mounting block. During this process, there is no need to manually press the limiting block, making the operation convenient.

[0011] Optionally, an abutment block is fixed to one end of the connecting rope extending from the mounting block.

[0012] By adopting the above technical solution, the abutment block restricts the connecting rope from fully entering the installation block, so that the operator can pull the connecting rope to retract the limiting block and disassemble the mother mold.

[0013] Optionally, the master mold is provided with a guide rod, which is vertically arranged and passes through the support rod.

[0014] By adopting the above technical solution, when the mounting block moves up and down with the master mold, the guide rod slides on the support rod. The vertically set guide rod plays a guiding role, thereby ensuring that the master mold moves in the vertical direction and is not prone to tilting. This ensures that when the master mold moves down to the lower mold, there will be no misalignment, thus improving the quality of the brick.

[0015] Optionally, the support frame has a through guide hole, the guide rod is adapted to pass through the guide hole, the inner wall of the guide hole has an annular groove, a plurality of balls are embedded in the annular groove, and the side wall of the balls contacts the side wall of the guide rod.

[0016] By adopting the above technical solution, when the master mold moves, it drives the guide rod to move in the guide hole, so that the side wall of the guide rod slides against the ball, thereby driving the ball to rotate. This transforms the sliding friction between the guide rod and the inner wall of the guide hole into rolling friction, reducing friction and facilitating the movement of the master mold while reducing the wear of the guide rod and extending its service life.

[0017] Optionally, a connecting hole is provided on the top wall of the female mold, the bottom end of the guide rod is inserted into the connecting hole, and the side wall of the guide rod is threadedly connected to the inner wall of the connecting hole.

[0018] By adopting the above technical solution, after the master mold is installed on the mounting block, the guide rod is aligned with the connecting hole and inserted, and the guide rod is rotated so that the guide rod is threadedly connected to the inner wall of the connecting hole, thereby achieving a fixed connection between the guide rod and the master mold. This means that each time different shaped bricks are produced, only the master mold needs to be replaced, and the guide rod does not need to be replaced.

[0019] Optionally, a disc is fixed to the top of the guide rod, and the disc can abut against the top wall of the support frame.

[0020] By adopting the above technical solution, when the master mold is removed, the bottom end of the guide rod loses its support and moves downward under the action of gravity until the disc abuts against the support frame. The disc ensures that the guide rod is always on the support frame, ready to be connected to the next master mold.

[0021] Optionally, a support plate is provided inside the lower mold, the circumferential sidewall of the support plate is fitted with the inner wall of the lower mold, the support plate is located at the bottom of the lower mold, and an electric push rod is provided inside the mounting base. The output end of the electric push rod is connected to the support plate and is used to drive the support plate to move up and down.

[0022] By adopting the above technical solution, when the concrete is placed in the lower mold and the mother mold is also placed on the lower mold, the electric push rod is activated to drive the support plate to move up, thereby pressing the concrete onto the mother mold. At this time, the mother mold and the support plate interact with each other, reducing the generation of voids and cracks in the concrete and improving the quality of the finished bricks.

[0023] In summary, this application includes at least one of the following beneficial effects:

[0024] 1. In use, first pour concrete into the lower mold, then start the cylinder to drive the mounting block to move the mother mold down until the mother mold covers the lower mold, thus pressing and shaping the soil in the lower mold. This achieves the preparation of irregularly shaped bricks. When it is necessary to prepare irregularly shaped bricks of different shapes, pull the connecting rope to pull the limiting block into the limiting hole for storage, making it easy to remove the mother mold from the mounting block. Then, align the mounting hole on the new mother mold with the mounting block and insert it, so that the limiting block is inserted into the positioning hole. At this time, the side wall of the limiting block abuts against the inner wall of the positioning hole, which plays a limiting role, so that the mother mold and the mounting block are fixedly connected. This allows for the replacement of the mother mold shape to adapt to the production of irregularly shaped bricks of different shapes without changing the entire structure of the mounting base, making the operation convenient.

[0025] 2. When the master mold moves, it drives the guide rod to move in the guide hole, causing the side wall of the guide rod to slide against the ball, thereby driving the ball to rotate. This transforms the sliding friction between the guide rod and the inner wall of the guide hole into rolling friction, reducing friction and facilitating the movement of the master mold while reducing wear on the guide rod and extending its service life.

[0029] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0030] This application discloses an irregularly shaped brick grinding tool. (Refer to...) Figure 1 and Figure 2 The irregular brick mold includes a mounting base 10, a lower mold 11, a support frame 20, a cylinder 21, a mounting block 30, and a female mold 40. The lower mold 11 is fixed on the mounting base 10, and the support frame 20 is provided on the top of the mounting base 10. The cylinder 21 is mounted on the support frame 20. The output end of the cylinder 21 is connected to the female mold 40 through the mounting block 30. The female mold 40 is located directly above the lower mold 11 and cooperates with it to complete the pressing action.

[0031] Reference Figure 1 and Figure 2 In order to facilitate the forming and demolding of irregular bricks, a support plate 13 is provided in the lower mold 11. The circumferential side wall of the support plate 13 is in contact with the inner wall of the lower mold 11. The support plate 13 is located at the bottom of the lower mold 11. An electric push rod 12 is provided in the mounting base 10. The output end of the electric push rod 12 is connected to the support plate 13 to drive the support plate 13 to move up and down.

[0032] When the concrete is placed in the lower mold 11 and the mother mold 40 is also placed on the lower mold 11, the electric push rod 12 is activated to drive the support plate 13 to move upward, thereby pressing the concrete onto the mother mold 40. At this time, the mother mold 40 and the support plate 13 interact to reduce the generation of voids and cracks in the concrete and improve the quality of the finished bricks.

[0033] After the irregular brick is pressed into shape, the female mold 40 moves upward, causing the female mold 40 to separate from the lower mold 11. The electric push rod 12 continues to drive the support plate 13 to move upward, thereby pushing the formed irregular brick out of the lower mold 11, which facilitates demolding.

[0034] Reference Figure 1 and Figure 2 Specifically, the mounting block 30 is inserted into the mounting hole 41 on the top wall of the female mold 40 for positioning. A limiting hole 31 is formed on the side wall of the mounting block 30, and a limiting block 50 and a limiting spring 52 are provided within the limiting hole 31. One end of the limiting spring 52 is fixed to the inner wall of the limiting hole 31, and the other end is fixed to the limiting block 50, used to drive the limiting block 50 to move away from the central axis of the mounting block 30. A thin steel wire connecting rope 53 is fixed to the part of the limiting block 50 inserted into the limiting hole 31, extending to the outside for manual operation. To prevent the connecting rope 53 from completely retracting into the mounting block 30, an abutment block 531 is fixed to the end of the connecting rope 53 extending out of the mounting block 30.

[0035] At the same time, a positioning hole 42 is machined on the inner wall of the mounting hole 41 corresponding to the position of the limiting block 50, so that the limiting block 50 can be accurately inserted into the positioning hole 42 to achieve a firm lock.

[0036] Reference Figure 1 and Figure 2The limiting block 50 has a guide surface 51 on its side wall away from the central axis of the mounting block 30. The bottom end of the guide surface 51 is inclined towards the central axis of the mounting block 30. During installation, the mounting hole 41 on the female mold 40 is aligned with the mounting block 30, and the female mold 40 is moved toward the mounting block 30. When the limiting block 50 reaches the mounting hole 41, the guide surface 51 abuts against the inner wall of the mounting hole 41. The mold continues to move, and the guide surface 51 acts as a guide, causing the inner wall of the mounting hole 41 to slide on the guide surface 51. This causes the limiting block 50 to gradually compress the connecting spring until the limiting block 50 is housed in the limiting hole 31, making it easy for the mounting block 30 to be inserted into the mounting hole 41. When the limiting block 50 is aligned with the positioning hole 42, the side wall of the limiting block 50 is unrestricted, the connecting spring returns to its original deformation, thereby pushing the limiting block 50 into the positioning hole 42, so that the mounting block 30 cannot be pulled out of the mounting hole 41, thus realizing the installation of the female mold 40 on the mounting block 30. During this process, there is no need to manually press the limiting block 50, making the operation convenient.

[0037] Reference Figure 1 and Figure 2 To improve dynamic stability, two parallel stainless steel guide rods 60 extend vertically upward from the female mold 40. A connection hole 43 is provided on the top wall of the female mold 40. The bottom end of the guide rod 60 is inserted into the connection hole 43 and threadedly connected to the inner wall of the connection hole 43.

[0038] These two guide rods 60 pass through the pre-drilled through holes 22 on the entire support frame 20, and an additional annular groove is added in the contact area to accommodate several balls 23, ensuring smooth rolling contact between the two rather than direct hard-impact wear. To avoid the risk of disengagement due to excessive lifting, a large-diameter metal disc 61 is specially welded at the top as a physical barrier for protection and restriction.

[0039] The implementation principle of the irregular brick mold in this application embodiment is as follows: In use, concrete is first poured into the lower mold 11. Then, the cylinder 21 is activated, driving the mounting block 30 to move the female mold 40 downwards until the female mold 40 covers the lower mold 11, thus pressing and shaping the clay in the lower mold 11. This achieves the preparation of irregular bricks. When it is necessary to prepare irregular bricks of different shapes, the connecting rope 53 is pulled to pull the limiting block 50 into the limiting hole 31 for storage, ensuring that the side wall of the mounting block 30 has no protrusions, making it easy to remove the female mold 40 from the mounting block 30. Next, align the mounting hole 41 on the new female mold 40 with the mounting block 30, and manually press the limiting block 50 so that the mounting block 30 can be smoothly inserted into the mounting hole 41. When the limiting block 50 in the mounting hole 41 reaches the positioning hole 42, the connecting spring returns to its original deformation, and the moving limiting block 50 is inserted into the positioning hole 42. At this time, the side wall of the limiting block 50 abuts against the inner wall of the positioning hole 42, which plays a limiting role, so that the female mold 40 and the mounting block 30 are fixedly connected. This realizes the replacement of the shape of the female mold 40 to adapt to the production of irregular bricks of different shapes without changing the entire structure of the mounting base 10, making the operation convenient.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
