A measuring device 16 is installed on the upper surface of the left adjustment plate 5. The two-way screws 3 on both sides are driven to rotate through the rotating chain 7 and the driving motor 9 in the transmission component, thereby driving the adjustment plate 5 to move along the inner wall of the sliding opening 41, so as to realize the casting and production of concrete slab components according to demand, thereby improving the diversification of the mold casting method. At the same time, the threaded rod 14 in the anti-leakage component rotates, thereby pushing the sliding block 13 to compress the buffer spring 12 along the inner wall of the adjustment plate 5, thereby enhancing the sealing performance of the sealing gasket 11 and the inner wall of the casting table 1, preventing the mud from leaking sideways at the bottom of the mold during the casting process, and causing the problem of troublesome cleaning of the casting table 1 in the later stage.
[0027] like Figure 1 and 4 As shown, it is convenient to remove bubbles in the concrete prefabricated parts more cleanly in the later stage. After each pouring, the bubbles in the concrete are pretreated first. A vibration table 19 is installed on the lower surface of the pouring table 1. Vibration springs 20 and resistors 21 are installed at the four corners of the lower surface of the vibration table 19. Scale plates 17 are installed on the front and rear sides of the upper surface of the installation cover 2. The upper surfaces of the two scale plates 17 are provided with multiple scale grooves 18.

[0029] Working principle: The utility model prevents the problem of side leakage during the pouring of cement through the anti-leakage component, and realizes the pouring of prefabricated plate component templates of different specifications through the transmission component. It is convenient and practical.

During the adjustment process, the adjustment distance is set in advance with the measuring device 16. The adjustment speed and accuracy are greatly improved, and the production efficiency of the product is improved. In order to prevent the side leakage of the mud during the pouring process, the turntable 15 is rotated to drive the threaded rod 14 to move up and down along the inner wall of the adjusting plate 5. While moving, the outer wall of the sliding block 13 is limited by the inner wall of the adjusting plate 5, thereby driving the sliding block 13 to move vertically together. By moving the sliding block 13, multiple buffer springs 12 are pushed downward, and the sealing gasket 11 is moved downward together. With the buffering force of the buffer spring 12, the sealing between the sealing gasket 11 and the casting table 1 is greatly improved, and the occurrence of mud leakage is prevented.
