[0001] The utility model relates to the technical field of hollow brick processing, and specifically relates to a hollow brick forming device. Background Art

[0002] As a commonly used wall main material in the construction industry, hollow bricks are light in weight, high in strength, and have good heat preservation, sound insulation and noise reduction performance. Hollow bricks are environmentally friendly and pollution-free, and are ideal filling materials for framed buildings. Hollow bricks are made of clay, shale, etc. as the main raw materials, and are processed through raw material treatment, forming, and sintering. The percentage of the total area of the holes in the hollow brick to the area of the brick is called the hole rate of the hollow brick, which should generally be above 40%. Compared with solid bricks, hollow bricks can save a large amount of land soil and brick burning fuel, reduce transportation weight; reduce the labor intensity during brick making and masonry, and speed up the construction progress; reduce the self-weight of the building, increase the number of building floors, and reduce the cost.

[0004] However, in the process of implementing the above technical solution, it is found that the above technical solution has the following technical problems:

[0005] The forming device of the hollow brick performs the demolding work by controlling the first die material frame and the second die material frame to move away from each other. In the actual application process, because the inner wall of the die material frame fits with the surface of the formed hollow brick and is basically in a sealed and pore-free state, it is easy to damage the surface of the hollow brick due to too much resistance during separation, thus affecting the quality of the hollow brick. Content of the Utility Model

Detailed implementation manners

[0026] The technical solutions in the embodiments of the present application are to solve the problems in the above background technology, and the general idea is as follows:

[0027] Embodiment 1:

[0028] This embodiment introduces the specific structure of a hollow brick forming device. Specifically, refer to Figures 1 - 4 As shown, it includes a forming outer mold 8, a forming top plate 18 arranged inside the forming outer mold 8, and a support plate 6 arranged at the bottom of the forming outer mold 8. Forming inner molds 17 are processed on the bottom surfaces at both ends of the forming top plate 18. A forming bottom plate 16 is processed on the top of the support plate 6. Positioning notches 15 are jointly processed inside both ends of the support plate 6 and the forming bottom plate 16. A device support 5 is arranged outside the forming outer mold 8. Cross plates 7 are assembled and connected to the top and middle of the device support 5. The support plate 6 is erected on the top of the cross plate 7;

[0029] Among them, during the production and processing of the hollow brick 14, a forming space is formed on the inner wall of the forming outer mold 8, the outer walls of the two forming inner molds 17, the bottom surface of the forming top plate 18, and the top surface of the forming bottom plate 16. Brick-making materials are injected into this forming space. By controlling the forming top plate 18 to move from top to bottom inside the forming outer mold 8, one end of each of the two forming inner molds 17 is respectively inserted and connected inside the two positioning notches 15, and finally, pressure is applied to the brick-making materials to make them into relatively dense-structured hollow bricks 14;

[0030] As Figure 1 shown, second hydraulic push rods 2 are assembled and connected to both ends of the cross plate 7 at the top, two first hydraulic push rods 1 are assembled and connected to the center of the cross plate 7 at the top. Outer auxiliary plates 4 are processed at the outer walls of both ends of the forming outer mold 8. An adapter flange 9 is arranged at one end of the first hydraulic push rod 1. The same connecting plate 3 is assembled and connected between one end of each of the two first hydraulic push rods 1 and one end of the two adapter flanges 9;

[0031] Among them, one end of the adapter flange 9 is assembled and connected to the top of the forming top plate 18, so that one end of the second hydraulic push rod 2 is assembled and fixed with the outer auxiliary plate 4, so that the two second hydraulic push rods 2 can control the forming outer mold 8 to move in the vertical direction, and the two first hydraulic push rods 1 can control the forming top plate 18 to move up and down inside the forming outer mold 8 and the forming inner mold 17 to slide inside the positioning notch 15, so as to form the hollow brick 14 on the inner side of the forming outer mold 8;

[0032] Secondly, in order to facilitate the insertion of one end of the two inner molding dies 17 into the two positioning notches 15, as shown in FIG. Figure 3 and Figure 4 As shown, a guide frame 19 is processed at one end of the inner molding die 17. By setting the cross section of the guide frame 19 to be an isosceles trapezoid (making the guide frame 19 a prism tube as a whole), the inner molding die 17 can be guided by the guide frame 19 and finally quickly inserted into the interior of the positioning notch 15;

[0033] At the same time, the two first hydraulic push rods 1 control the upward and downward movement of the forming top plate 18 through the connecting plate 3 and the two adapter flanges 9, and control the two forming inner molds 17 at the bottom of the forming top plate 18 to move toward the bottom, thereby correcting the position of the support plate 6 at the top of a horizontal plate 7, without the need to over-calibrate the position of the support plate 6.

[0034] By adopting the above technical solution:

[0035] The above design uses the inner wall of the outer molding die 8, the outer walls of the two inner molding die 17, the bottom surface of the molding top plate 18 and the top surface of the molding bottom plate 16, and uses the two second hydraulic push rods 2 to control the outer molding die 8 to move to the top of the support plate 6, and uses the two first hydraulic push rods 1 to control the molding top plate 18 to move from the top to the bottom inside the outer molding die 8, so that the two inner molding dies 17 at the bottom of the molding top plate 18 are inserted into the inside of the two positioning notches 15 inside the molding bottom plate 16, and while correcting the positions of the molding bottom plate 16 and the positioning notches 15, the outer molding die 8 is pressed against the top of the support plate 6, the outer molding die 8 and the support plate 6 are sealed, and the molding top plate 18 drives the two inner molding dies 17 to move toward the top;

[0036] Subsequently, the brick-making material is injected between the outer molding die 8, the two inner molding die 17, the molding top plate 18 and the molding bottom plate 16. The outer molding die 8 can be controlled to move toward the bottom with the help of the two second hydraulic push rods 2, and finally a hollow brick 14 with a relatively dense texture is formed. When demolding, the two second hydraulic push rods 2 are used to control the outer molding die 8 to move toward the top, and the two first hydraulic push rods 1 control the molding top plate 18 to drive the molding inner mold 17 to move from the inside of the outer molding die 8 to the top. The relative sliding of the planes can be used to avoid damage to the hollow bricks 14, and the yield rate is high and the quality is good.

[0037] Example 2:

[0038] Based on Example 1, this example introduces the specific structure of the forming top plate 18. As Figures 2 to 4 shown, a switching disk 12 is rotatably connected to the top of the forming top plate 18. A blanking pipe 10 is machined at the top of one side of the switching disk 12, and a round hole is machined inside the forming top plate 18;

[0039] Among them, the center of the bottom of the switching disk 12 is connected to the top of the forming top plate 18 through a bearing and a shaft rod (without special design, only to keep the switching disk 12 rotatable on the top of the forming top plate 18, not elaborated). When the inside of the blanking pipe 10 is communicated with the round hole inside the forming top plate 18, the brick-making material can be injected into the inner side of the forming outer mold 8 through the blanking pipe 10, without disconnecting the forming top plate 18 from the forming outer mold 8. During demolding, the forming outer mold 8 and the forming top plate 18 can be respectively controlled to move upward;

[0040] Secondly, in order to facilitate controlling the rotation of the switching disk 12 on the top of the forming top plate 18, as Figure 2 and Figure 3 shown, a column 13 is machined at the center of the top of the switching disk 12, and a rotary air rod 11 is arranged at the top of the column 13 (the rotation angle of the rotary air rod 11 is 30 degrees to 60 degrees). By assembling the rotary air rod 11 at the center of the top of the connecting plate 3, one end of the rotating shaft of the rotary air rod 11 is in transmission connection with the column 13, and the rotary air rod 11 can be used to control the column 13 to drive the switching disk 12 to rotate on the top of the forming top plate 18;

[0041] At the same time, when the rotary air rod 11 drives the blanking pipe 10 to switch the communication state with the round hole inside the forming top plate 18 through the column 13 and the switching disk 12, it can avoid excessive overflow of the brick-making material from the inside of the forming outer mold 8 when the forming top plate 18 presses the brick-making material downward inside the forming outer mold 8 to form the hollow brick 14.

[0042] By adopting the above technical solutions:

[0043] The above design sets a switching disk 12 with a blanking pipe 10 on the top of the forming top plate 18, and connects a rotary air rod 11 at the center of the top of the switching disk 12 through a column 13. When the rotary air rod 11 controls the column 13 to drive the switching disk 12 to rotate, the state of the blanking pipe 10 and the round hole inside the forming top plate 18 is adjusted, which is convenient for injecting the brick-making material into the inner side of the forming outer mold 8 through the blanking pipe 10 and the round hole on the forming top plate 18 according to the requirements of the formation of the hollow brick 14, or blocking the round hole on the forming top plate 18 to meet the actual production needs.

[0044] Finally, it should be noted that: Obviously, the above embodiments are merely examples given to clearly illustrate the present utility model, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present utility model.
