Vertical vibration mold for flexible large-diameter pipeline

The invention discloses a vertical vibration mold for a flexible large-diameter pipeline. Relates to a concrete pipe preparation mold. Comprising an inner mold used for molding the inner side wall of the pipeline; the outer mold is arranged on the outer side of the inner mold in a sleeving manner; the bottom die is adjustably arranged between the inner die and the outer die to form a prefabricating cavity matched with the pipeline; and the socket mold is fixedly arranged at the top of the outer mold and is matched with the inner mold. And the inner mold supporting round body is matched with the inner side wall of the inner mold. And the inner mold supporting round body comprises an outer supporting part matched with the inner mold. The bottom die is fixed between the inner die and the outer die in a sealed mode through the connecting pieces, a pouring cavity matched with a pipeline of the needed specification is formed, the utilization rate of the die is greatly increased, installation is easy and convenient,
