When the motor 2 (415) is working, it drives the fixed plate 1 (44) and the vibrating motor (43) to rotate through the gear 3 (413) and the gear 4 (414), so that the vibrating head rotates in the mold (3); S3, after the right side mold (3) is filled and the front side is vibrated, the motor 1 (26) is controlled to work again so that the turntable (21) rotates 90 degrees, and then the left side pouring head (47) is used to add concrete slurry into the vibrated mold (3) to fill the mold (3). At the same time, the above actions are repeated to perform the grouting and vibrating operations at the same time, and then the filled mold (3) is adjusted to the rear side of the turntable (21), and the electric push rod 2 (11) is controlled to extend so that the connecting frame (10) and the push plate (13) move to the left. When the push plate (13) moves to the left, the rear side mold (3) is pushed to the left, so that the rear side mold (3) slides to the storage via the support plate (9). At this time, the electric push rod (11) is controlled to retract so that the push plate (13) moves to the right side of the rear positioning assembly, and then the user pulls the mold (3) at the right end of the storage tray (5) to slide along the rolling roller (6) to the left end of the storage tray (5). At this time, the heating plate (15) can be controlled to work to dry the preforms in the upper storage tray (5). Subsequently, multiple molds (3) can be placed on the storage tray (5) in sequence. When the storage tray (5) is full of molds (3), the storage tray (5) is pulled to slide along the rolling roller (6) to the front end of the drying tray (7), and then the empty storage tray (5) is placed at the rear end of the drying tray (7).
