Abstract

The utility model discloses a rotational moulding mold with reinforcing ribs. The plastic rolling mold comprises a plurality of semi-circular upper molds, a plurality of semi-circular lower molds, end sockets, a plurality of first reinforcing ribs and a plurality of second reinforcing ribs, wherein the semi-circular upper molds and the semi-circular lower molds are mutually buckled to form a hollow cylindrical tank body. The end sockets are buckled with the semi-circular upper molds and the semi-circular lower molds. The first reinforcing ribs and the second reinforcing ribs protrude outward and extend out of the outer surfaces of the upper molds and the lower molds in radial direction, and are perpendicular to the axial direction of the tank body, and the cross sections of the first reinforcing ribs and the second reinforcing ribs are in semi-circular hollow structure. The rotational moulding mold is effectively prevented from creeping deformation, prolongs service life, and enhances size accuracy of rotational moulding products produced through the rotational moulding mold.
