Description

Technical Field

[0001] The utility model relates to a test cement block manufacturing mold, belonging to the technical field of cement block manufacturing molds. Background Art

[0002] In construction projects, cement and other mixed materials are needed to make cement blocks, and then they are used. In order to ensure the quality of the construction project, it is necessary to conduct multiple tests on the cement blocks to ensure that the quality of the cement blocks is qualified. Therefore, it is necessary to use cement block making molds to make test cement blocks.

[0003] According to announcement number CN203994172U, a cement block manufacturing mold is disclosed, which uses four rectangular steel plates, two of which are of equal length and two of which are of equal shortness, to be welded into a rectangular frame. The size of the frame is the same as the required size of the cement block. A handle with bent ends is welded on each side of the short side of the frame to form a mold for manufacturing cement blocks. On a platform for collecting cement blocks, compacted cubic cement blocks consisting of a cement-sand-gravel mixture are neatly arranged, which speeds up the manufacturing of cement blocks, saves costs, and also saves resources.

[0004] However, the above device is not convenient for leveling the surface of the cement block when in use. At the same time, after the cement block is formed, the user pulls the mold upward, which easily causes the cement block to move upward with the mold, making it inconvenient to demould the cement block.
