[0003] The existing patent (announcement number: CN212568148U) discloses a fair-faced concrete simulation test mold, which comprises two stainless steel molds and two stainless steel side plates symmetrically arranged on the two sides of the two stainless steel molds, the upper and lower ends of the stainless steel side plates have right-angle flanges, the right-angle flanges of the two stainless steel connecting plates are outwardly arranged, and the right-angle flanges and the stainless steel molds are fastened by bolt clamps. The utility model is easy to manufacture and disassemble, can conveniently and environmentally protectively achieve the purpose of predicting the appearance effect of the formed concrete, and can adjust and optimize the mixing ratio according to the appearance, can find the best mixing ratio design elements including material selection, sand ratio, dosage of additive, dosage of functional material, and can also indirectly guide various parameters that need to be paid attention to in the concrete construction process, including vibration time and demolding time. Because the material is consistent with the material of the mold used in the project, the surface of the fair-faced concrete produced is flat and clean, and the project guidance is more instructive and predictive.

[0004] The fair-faced concrete simulation test mold disclosed in the above-mentioned patent needs to be demolded after the concrete solidifies, and the test block surface is flush with the mold surface, which makes it inconvenient to apply force to the test block during demolding, so that the worker needs to use a rubber hammer to knock the mold during demolding, break the adhesion between the test block surface and the mold through vibration, separate the two, then take out the mold, and finally take out the test block by relying on the gravity of the test block itself to make the test block slide out of the mold, which increases the working intensity of the worker and reduces the demolding efficiency of the test block. Practical new type content

[0005] In view of the defects of the prior art, the clear water concrete test mold has the advantages of facilitating demolding, solves the problem that demolding operation needs to be performed after the concrete solidifies in actual use, the inner surface of the mold is closely adhered, the surface of the test block is flush with the surface of the mold, force cannot be easily applied to the test block during demolding, the worker needs to use a rubber hammer to knock the mold during demolding, the adhesion between the surface of the test block and the mold is broken through vibration, the test block is separated from the mold, the mold is picked up, the test block is slid out of the mold by the gravity of the test block, and the test block is taken out, the working strength of the worker is increased, and the demolding efficiency of the test block is reduced.

[0007] Through the above scheme, the threaded rod is provided, the rotating seat is rotatably arranged at the lower end of the threaded rod, the top plate is fixedly arranged at the lower end of the rotating seat, the rotating handle is rotated after the concrete solidifies, the rotating handle drives the threaded rod to rotate, the top plate moves downward while the threaded rod rotates, until the top plate contacts the upper end of the test block, the top plate applies a downward pushing force to the test block while the rotating handle is continuously rotated, thereby driving the test block to move and push the test block out of the mold body, the demolding difficulty is reduced, and the test block demolding efficiency is improved.

[0008] Further, two mirror image distributed guide columns are fixedly connected to the upper end surface of the top plate, and baffles are fixedly connected to the upper ends of the two guide columns and penetrate the connecting frame.

[0009] Through the above scheme, the two guide columns prevent the threaded rod from rotating with the top plate during rotation, thereby ensuring that the top plate can only move linearly along the axial direction of the guide column.

[0010] Further, a rotating handle is fixedly connected to the upper end of the threaded rod.

[0011] Through the above scheme, the rotating handle provides a larger operation area, so that the operator can more easily hold and rotate the threaded rod.

[0012] Further, the bottom plate is slidably connected inside the lower end of the mold body, and a sealing block is fixedly connected to the surface of the bottom plate.

[0013] Through the above scheme, the sealing block and the sealing groove inner wall are slidably connected, which ensures that the sealing block can always tightly fit on the inner wall of the sealing groove, thereby realizing good sealing of the lower end of the mold body, effectively preventing concrete from leaking from the lower end of the mold body during pouring and solidification, and ensuring the integrity and accuracy of the test block.

[0014] Further, the upper connecting plate is fixedly connected to both sides of the lower end of the mold body, and the lower connecting plate corresponding to the upper connecting plate is fixedly connected to both sides of the bottom plate.

[0016] Further, the lower connecting plate is slidably connected inside the lower connecting plate, and the nut is threadedly connected to the lower connecting plate and the upper connecting plate at one end of the bolt.

At the same time, start the vibration motor during demolding, and the vibration motor will drive the mold body to vibrate, thereby breaking the adhesion between the surface of the test block and the mold body, making the demolding process easier.

[0020] Further, the installation frame is fixedly connected to four supporting blocks at the lower end, and the rubber buffer pad is fixedly connected to the lower end of each of the four supporting blocks.

[0021] Through the above scheme, the four supporting blocks not only provide stable supporting points for the mold, but also reduce the pressure on the test table or the ground by dispersing the weight of the mold. Meanwhile, the rubber buffer pad is made of rubber material with elasticity and wear resistance, which can effectively absorb the vibration and impact force generated during the use of the mold, thereby protecting the test table or the ground from damage.

[0022] Compared with the prior art, the technical scheme of the application has the following beneficial effects:

[0023] The clean concrete test mold is provided with a threaded rod, a rotating seat is arranged at the lower end of the threaded rod, a top plate is fixedly arranged at the lower end of the rotating seat, and after the concrete solidifies, the rotating handle is rotated to drive the threaded rod to rotate, and the threaded rod rotates while driving the top plate to move downward until the top plate contacts the upper end of the test block. When the rotating handle is continuously rotated, the top plate will exert a downward pushing force on the test block, thereby driving the test block to move and push the test block out of the mold body. Meanwhile, the vibration motor can uniformly transmit vibration to the entire mold body when working, and the vibration helps the concrete to be more uniformly distributed and compacted in the mold body through the vibration effect, thereby improving the forming quality and accuracy of the test block. Meanwhile, the vibration motor is started during the demolding process, and the vibration motor drives the mold body to vibrate, thereby breaking the adhesion between the surface of the test block and the mold body, making the demolding process easier, reducing the difficulty of demolding, and improving the efficiency of test block demolding.
