[0025] In the description of the present application, unless otherwise clearly defined, words such as setting, installation, and connection should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above words in the present application in combination with the specific content of the technical solution.

[0026] Please refer to Figure 1 and Figure 2 , a mold for adjusting the size of cement bricks, the mold includes a mold body 1 and a limit component 2 arranged in the mold body 1. The mold body 1 includes a front mold 101. The limit component 2 includes a connecting rod 201, a rotating lead screw 202, and a connecting piece 203. An installation groove 2036 is formed inside the side of the connecting piece 203 close to the front mold 101. A reciprocating nut 2037 is arranged in the installation groove 2036. The rotating lead screw 202 passes through the reciprocating nut 2037 and is connected to the connecting piece 203 through the reciprocating nut 2037. A cavity 1011 is opened in the front mold 101. The side of the connecting piece 203 provided with a through hole is accommodated in the cavity 1011, and the other side is connected to the connecting rod 201.

[0027] When this application is in use, by rotating the rotating screw rod 202, since the threads in the reciprocating nut 2037 cooperate with the threads on the outer wall of the rotating screw rod 202, the reciprocating nut 2037 will move linearly along the axial direction of the rotating screw rod 202, and drive the connecting rod 201 connected to the connecting member 203 to also move horizontally on the bottom mold 102 in a direction perpendicular to the front mold 101, thereby achieving the effect of adjusting the pouring size of the precast cement brick. Finally, pour cement into the mold with adjusted size.

[0028] This application is not only convenient to operate, but also can be adapted to the pouring of cement bricks of different sizes. Construction management personnel do not need to purchase different specifications of cement bricks through multiple channels, reducing the procurement procedures; due to the simple structure of this application, construction units can manufacture the molds by themselves and mass-produce the cement bricks required for this project, which is of great significance for reducing project cost and shortening the construction period.

[0029] Preferably, a bolt 205 can be provided near the position of the retaining piece 204. The rotating screw rod 202 passes through the bolt 205 and is fixedly connected to the bolt 205. When rotating the rotating screw rod 202, the bolt 205 can be rotated by using a tool, thereby driving the rotation of the rotating screw rod 202, which is convenient for workers to operate and saves time and effort.

[0030] Optionally, the tool for rotating the bolt 205 can be an electric screwdriver, a pneumatic screwdriver or an electric wrench, etc., and no more restrictions are made here.

[0031] Preferably, after pouring cement into the mold, wait for the cement to initially solidify in the mold, rotate the rotating screw rod 202 to make the connecting rod 201 move away from the cement brick, so that it disengages from the cement brick, then reverse the mold and gently tap to take out the cement brick from the mold, and then cure the taken-out cement brick to make it harden and form. The curing method can be natural curing, steam curing, etc., and no more restrictions are made here.

[0032] As Figure 3 shown, a guide rail 1012 is provided on one side of the front mold 101 close to the connecting rod 201. The connecting member 203 is slidably connected to the front mold 101 through the guide rail 1012. The two guide plates 10121 on one side of the front mold 101 close to the connecting rod 201 are combined to form the guide rail 1012. When adjusting the size of the cement brick in this application, rotate the rotating screw rod 202. While the reciprocating nut 2037 moves linearly in the axial direction of the rotating screw, it will also rotate under the drive of the rotating screw rod 202, thus affecting the operation of the worker. The design of the guide rail 1012 can limit the degree of freedom of rotation of the reciprocating nut 2037, so that it always remains in the correct position during the linear movement, to ensure the smooth movement of the connecting member 203 and only move along the axial direction of the rotating screw rod 202.

[0033] Specifically, an arc convex surface 10122 is formed on the end face of the guide rail 1012. When the present application is in use, the connecting member 203 moves along the axial direction of the rotating lead screw 202. The arc convex surface 10122 enables the outer wall of the first rectangular body 2031 to cooperate with the front mold 101, reducing the friction force of the movement of the connecting member 203 and facilitating the operation of workers.

[0034] As Figure 2 and Figure 3 As shown, the connecting member 203 includes a first rectangular body 2031 and a second rectangular body 2033. The rotating lead screw 202 passes through the second rectangular body 2033 and is connected to the second rectangular body 2033 through a reciprocating nut 2037. One side of the first rectangular body 2031 is connected to the second rectangular body 2033. Preferably, the height of the first rectangular body 2031 is slightly smaller than the width of the guide rail 1012 so that the connecting member 203 can slide on the guide rail 1012.

[0035] Specifically, a stepped body 2032 is provided on the other side of the first rectangular body 2031. The cross-sectional shape of the stepped body 2032 is set to a stepped shape. The connecting member 203 and the connecting rod 201 are fixedly connected through a fastener 207. When installing the connecting member 203 and the connecting rod 201, rotating the fastener 207 will inevitably cause the connecting member 203 to be under pressure. By setting the cross-sectional shape of the stepped body 2032 to a stepped shape, it plays a role similar to the stepped foundation in the construction industry, and can better adapt to and disperse the stress received, preventing the connecting member 203 or the connecting rod 201 from deforming.

[0036] Specifically, the connecting member 203 further includes a reinforcing piece 2034. One end of the reinforcing piece 2034 is fixed on the first rectangular body 2031, and the other end is fixed on the second rectangular body 2033. The reinforcing piece 2034 can prevent the overall stability of the connection structure when the present application is subjected to extrusion or impact, and extend the service life of the mold.

[0037] Specifically, a washer 2034 is provided at the position where the connecting member 203 is connected to the connecting rod 201. When the operator fixes the connecting member 203 and the connecting rod 201, the washer 2034 can disperse the pressure between the fastener 207 and the connecting rod 201, preventing stress concentration. At the same time, when the mold is subjected to sudden impact or vibration, the washer 2034 can play a buffering role, reducing the impact on the connection structure of the connecting member 203 and the connecting rod 201, further improving the connection stability and extending the service life of the mold.

[0038] As Figure 1As shown, the mold body 1 includes a bottom mold 102 and a scale 103. The scale 103 is arranged between the connecting piece 203 and the bottom mold 102 and fixedly connected to the bottom mold 102. When workers adjust the size of the cement bricks to be poured, the scale 103 helps workers more intuitively and accurately determine the size of the cement bricks, ensuring the quality of the produced cement bricks.

[0039] As Figure 2 shown, the limiting component 2 further includes a baffle 204. The baffle is arranged on both sides of the front mold and fixedly connected to the rotating screw rod. The baffle 204 can prevent external sundries and dust from entering the cavity 1011, reducing the difficulty of mold cleaning.

[0040] As Figure 1 shown, a handle 206 is arranged on the outer wall of the front mold 101. Since the mold has a certain weight, it is rather strenuous for workers to transfer the mold. The design of the handle 206 can effectively improve the efficiency of workers in transferring the mold and save time.

[0041] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
