The utility model discloses a vertical mold vibration device, which is suitable for prefabricating a vertical combined mold for manufacturing concrete slab components. Vibration wave generating equipment that acts as a vibration driving force for a vertical mold, the lower end face of the vibration beam is provided with a support for supporting the vibration beam, and the vibration wave generating equipment is arranged in the space enclosed by the vibration beam and the support; The utility model has the advantages of scientific and simple structure, controllable vibration force, stable and practical performance, and the use of the device makes the inner dense surface of the plate-type components produced by the vertical composite mold smooth, and avoids the leakage of vibration and uneven vibration caused by manpower vibration, which may affect the quality of the components. The impact of the vibration has realized the change from manual vibration to electronically controlled vibration, which effectively reduces the labor intensity of workers, improves product quality, and is conducive to industrialized large-scale production, which opens up new methods for automated production in this industry.
