During demoulding, the movable plate 8 is driven away from the fixed plate 2, and the restriction of the limiter 4 is released to drive the long partition 3 and the mold bottom plate 1 to move relative to each other, so that the molded prefabricated parts appear from the mold, which is convenient for demoulding of the prefabricated parts after casting and molding. After multiple uses, the concrete adhered to the inner wall of the mold can be shoveled and cleaned.

[0044] The working principle of the concrete prefabricated part blank making mold provided by the utility model is as follows:

[0045] When in use, when it is necessary to prefabricate concrete prefabricated parts of different thicknesses, first release the restriction of the limiting member 4 on the limiting hole 301, then pull the connecting frame 5 up and down, thereby driving the two long partitions 3 to slide on the slots 101 until the height of the long partitions 3 extending out of the slots 101 is adjusted to match the thickness of the prefabricated parts, then turn the hand wheel 42 to drive the bidirectional threaded rod 41 to rotate, thereby driving the L-shaped frames 43 on both sides to drive the pin rod 44 to insert into the new limiting hole 301 to complete the height adjustment. After adjustment, when it is necessary to adjust the length of the prefabricated parts, by turning the adjusting rod 73, the adjusting rod 73 drives The worm gears 74 on both sides rotate synchronously, so when they rotate, they mesh with the worm wheel 72, thereby driving the screw rod 71 to rotate. When the screw rod 71 rotates, it drives the cross plate 6 to slide along the slide groove 501, thereby adjusting the distance between the movable plate 8 and the fixed plate 2 to achieve length adjustment, and then the handle 93 is turned to drive the screw rod 92 to rotate. When the screw rod 92 rotates, it drives the pressure block 94 to approach the movable plate 8 and squeeze the movable plate 8 downward on the mold bottom plate 1 to complete the fixation of the movable plate 8. After adjustment, the precast parts can be cast. The entire mold structure is simple, the adjustment is very convenient, and the application range is wide.
