BLOW MOLDING APPARATUS Abstract of the Disclosure A blow molding apparatus comprising a wheel plate, a shaft extending horizontally and supporting the wheel plate for rotation and a hub removably mounted on the shaft for rotation with the shaft, and a plurality of sets of molds defining a mold cavity when closed, each set comprising a pair of mold sections, a first mold section of each set being mounted on the hub such that the sets are circumferentially spaced about the hub, a second mold section of each set being mounted on the wheel in circumferentially spaced relation and radial alignment with the first mentioned mold section. The second mold sections axe mounted on slide assemblies for supporting the second mold sections for movement toward and away from the first mold sections. The hub has circumferentially spaced external surfaces for supporting the first mold sections, the number of surfaces corresponding to the number of first mold sections. The hub may be removed and replaced on the shaft by a second hub having a plurality of circumferentially spaced surfaces, the number of the surfaces of the second hub differing from the number of surfaces of the first hub. The wheel plate accommodates a different number of slide assemblies to correspond with the different number of mold surfaces of the second hub.
