The invention discloses a one-piece hermetically molded marine floating ball, including a hollow sealed outer shell in the shape of an elongated cylinder. Four upper vertical wings are erected in a cross arrangement on the top of the outer shell, and one upper connecting through hole is formed at the outer end of each pair of opposite upper vertical wings, with the top ends of all four upper vertical wings located on the same horizontal plane. Four lower vertical wings protruding downward in a cross layout are arranged at the bottom of the outer shell, and one lower connecting through hole is provided at the outer end of each pair of opposite lower vertical wings. The invention also discloses a molding device and a preparation method for the floating ball. The design realizes one-step blow molding and sealing production of the floating ball, maintains internal air pressure, enhances structural strength and buoyancy, overcomes the defects of traditional floating balls, improves product durability, and meets diversified high-standard application requirements.
