Abstract
A die for manufacturing CVJ boot by injection molding includes a central core, and a plurality of divisional molds for molding an inner peripheral surface of the CVJ boot, respectively. The divisional molds move diametrically toward the central core. Moreover, the divisional molds not only approach one another diametrically, but also get away from each other axially.
