Description

Technical Field

[0001] This utility model relates to the technical field of building material processing, and in particular to a hollow brick pressing device. Background Technology

[0002] Hollow bricks are bricks with a porosity of 35% or greater, and small number and large pores. They are commonly used in non-load-bearing parts. Hollow bricks can be divided into cement hollow bricks, clay hollow bricks, and shale hollow bricks. Hollow bricks are a commonly used wall material in the construction industry. Due to their advantages such as being lightweight and requiring less raw materials, they have become the first product recommended by construction departments.

[0003] In the process of preparing hollow bricks, a pressing device is often used to press and shape the hollow bricks. In the existing technology, the hollow brick pressing device usually pours the hollow brick raw material into the mold for extrusion molding. After extrusion molding, it is necessary to wait for the raw material to cool naturally before taking out the shaped hollow brick. This results in low efficiency in the hollow brick pressing and molding process. Moreover, when the hollow brick is poured out of the mold during the demolding process, it is easy to damage the hollow brick, resulting in a low yield of pressed hollow bricks. Utility Model Content

[0004] In view of the shortcomings of the prior art, the present invention provides a hollow brick pressing device, which has high pressing efficiency for hollow bricks and prevents damage during the demolding process of the formed hollow bricks.

[0005] To solve the above-mentioned technical problems, the present invention proposes the following technical solution:

[0006] A hollow brick pressing device includes a base, a pressing table slidably disposed on the base, a frame fixed on the base, a lifting frame movably disposed in the frame, a pressing plate fixedly connected to the bottom of the lifting frame, a hollow plate movably disposed in the pressing plate, a mold movably disposed on the pressing table, the pressing plate movably disposed above the mold, and a pipe installed inside the mold.

[0007] Furthermore, a guide rail is installed on the base, and the bottom of the pressing table is slidably mounted on the guide rail.

[0008] Furthermore, a first hydraulic cylinder is installed at the bottom of the frame, and the telescopic end of the first hydraulic cylinder is connected to the lifting frame. The two ends of the lifting frame are slidably arranged inside the frame.

[0009] Furthermore, a third hydraulic cylinder is installed at the bottom of the lifting frame. The telescopic end of the third hydraulic cylinder is connected to the hollow plate. A through hole is opened in the center of the pressing plate. The hollow plate is slidably disposed in the through hole. A connecting rod is fixedly connected between the lifting frame and the pressing plate.

[0010] Furthermore, a groove is provided on the side of the frame, and a slider is slidably provided in the groove. A first connecting plate and a second connecting plate are fixed to both ends of the slider, respectively. The first connecting plate is fixed to the side of the mold. An extension plate is fixed to the side of the frame, and a second hydraulic cylinder is installed at the bottom of the extension plate. The telescopic end of the second hydraulic cylinder is connected to the second connecting plate.

[0011] Furthermore, the two ends of the pipe are respectively connected to an inlet and an outlet, and the inlet and outlet are respectively connected to a water supply tank and a water collection tank, and the pipe is wound around the mold.

[0012] As can be seen from the above technical solution, the beneficial effects of this utility model are:

[0013] This invention features a pressing platform that slides on a base, with a mold movable on the pressing platform. The mold can be raised and lowered to expose the pressed hollow bricks. The hollow bricks can be picked up and put down by sliding the pressing platform.

Detailed Implementation

[0020] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0021] See Figure 1-3 A hollow brick pressing device includes a base 1, a pressing table 3 slidably disposed on the base 1, a frame 4 fixed on the base 1, a lifting frame 6 movably disposed in the frame 4, a pressing plate 14 fixedly connected to the bottom of the lifting frame 6, a hollow plate 15 movably disposed in the pressing plate 14, a mold 7 movably disposed on the pressing table 3, the pressing plate 14 movably disposed above the mold 7, and a pipe 19 installed inside the mold 7.

[0022] In practical use, a pressing table 3 is slidably set on the base 1, and a mold 7 is movably set on the pressing table 3. The hollow bricks are exposed by raising and lowering the mold 7. The hollow bricks are picked up and put down by sliding the pressing table 3. By setting a pipe 19 in the mold 7, cooling water is introduced into the pipe 19 to quickly cool the pressed hollow bricks and ensure work efficiency.

[0023] In this embodiment, a guide rail 2 is installed on the base 1, and the bottom of the pressing table 3 is slidably disposed on the guide rail 2; specifically, the setting of the guide rail 2 facilitates the overall movement of the pressing table 3, thereby making it easier to pick up the pressed hollow bricks.

[0024] In this embodiment, a first hydraulic cylinder 5 is installed at the bottom of the frame 4. The telescopic end of the first hydraulic cylinder 5 is connected to the lifting frame 6, and the two ends of the lifting frame 6 are slidably disposed on the inner side of the frame 4. A third hydraulic cylinder 12 is installed at the bottom of the lifting frame 6. The telescopic end of the third hydraulic cylinder 12 is connected to the hollow plate 15. A through hole is opened in the center of the pressing plate 14, and the hollow plate 15 is slidably disposed in the through hole. A connecting rod 13 is fixedly connected between the lifting frame 6 and the pressing plate 14. Specifically, the lifting frame 6 can be driven to rise and fall by starting the first hydraulic cylinder 5. The rising and falling of the lifting frame 6 can drive the pressing plate 14 to move and press the hollow brick raw material. The hollow plate 15 can be driven to rise and fall by starting the third hydraulic cylinder 12, thereby hollowing out the inside of the hollow brick and realizing the overall forming of the hollow brick.

[0025] In this embodiment, a groove 18 is provided on the side of the frame 4, and a slider is slidably provided in the groove 18. A first connecting plate 8 and a second connecting plate 9 are respectively fixed to both ends of the slider. The first connecting plate 8 is fixed to the side of the mold 7. An extension plate 10 is fixed to the side of the frame 4. A second hydraulic cylinder 11 is installed at the bottom of the extension plate 10. The telescopic end of the second hydraulic cylinder 11 is connected to the second connecting plate 9. Specifically, the second connecting plate 9 can be moved by starting the second hydraulic cylinder 11. The lifting and lowering of the second connecting plate 9 can drive the first connecting plate 8 and the slider to lift and lower synchronously, thereby driving the mold 7 to follow the lifting and lowering. This facilitates the demolding of the pressed hollow brick by lifting and lowering the mold 7.

[0026] The frame 4 has a second hydraulic cylinder 11 on both sides, and the two second hydraulic cylinders 11 are cylinders that start synchronously.

[0027] The surface of the pressing table 3 and the inner wall of the mold 7 are both made of smooth, non-stick materials.

[0028] In this embodiment, the two ends of the pipe 19 are respectively connected to the inlet 16 and the outlet 17. The inlet 16 and the outlet 17 are respectively connected to the water supply tank and the water collection tank. The pipe 19 is wound around the mold 7. Specifically, water can be supplied to the inlet 16 through the water supply tank, so that the water source enters the pipe 19, absorbs the heat of the raw material after pressing in the mold 7, and collects the heat-absorbing water source through the water collection tank.

[0029] The water supply tank and water collection tank are existing technologies and therefore will not be described in detail in the instruction manual and its accompanying drawings. The water flow rate in the pipe is sufficient to absorb the heat in the mold 7. The pipe 19 is fitted to the inner wall of the mold 7, which effectively absorbs the heat in the mold 7. Both the water inlet 16 and the water outlet 17 are made of flexible pipe material, which facilitates the raising and lowering of the mold 7.

[0030] The surfaces of the mold 7 and the pressing table 3 can be connected by a weak magnetic field, which can ensure the airtightness of the mold 7 and the pressing table 3 after they are attached. At the same time, the mold 7 and the pressing table 3 are easy to separate after being connected by a weak magnetic field.

[0031] Working principle: The operator controls the mold 7 to fit the surface of the pressing table 3, pours the hollow brick raw material into the mold 7, controls the first hydraulic cylinder 5 to drive the pressing plate 14 to press the hollow brick raw material in the mold 7, controls the third hydraulic cylinder 12 to drive the hollow plate 15 to lift and lower independently to hollow out the hollow brick. After extrusion molding, water is injected into the water pipe 19 to cool the hollow brick in the mold 7. After cooling, the second hydraulic cylinder 11 is controlled to drive the mold 7 to rise, realizing the demolding of the mold and the hollow brick. The sliding pressing table 3 realizes the removal of the demolded hollow brick.
