<p>A mold for molding hollow spherical body includes a spherical core positioned between a first mold body and a second mold body. When the first mold body is overlaid on the second mold body, a spherical cavity is defined therebetween and the spherical core is suspended in the spherical cavity. The spherical core has an outer diameter smaller than inner diameter of the spherical cavity so that a ball wall molding space is defined between the spherical core and the spherical cavity for molding the hollow spherical body. The mold-closing line of the spherical cavity is identical to the original stripes of the surface of the spherical body as the plate interconnection line of a soccer ball so that the spherical body can have a unified appearance. In addition, the spherical core is suspended in the spherical cavity in a true position to ensure the roundness of the spherical body.</p> |
