Abstract
A disk rotor is produced using pre-forms. A manufacturing deviceincludes lower moldand upper mold. The lower moldincludes support block, main body part of the lower mold, inclined pins, core elementsand slider. In securing and supporting pre-formsA,A, a cylinderis actuated to cause upward movement of the support blockand the main body part of the lower mold, during which movement, core elementsand sliderare slid relatively outwards along inclined pins. In this state, the pre-formsA,A are guided to preset sites. The support blockand the main body part of the lower moldare then moved downwards, during which movement, core elementsand sliderare slid relatively inwards along the inclined pins. In this state, the pre-formsA,A are supported and secured stably to define a cavity.
