ABSTRACT:
A disk rotor is produced using pre-forms. A manufacturing device10includes lower mold11and upper mold12. The lower mold11includes support block13, main body part of the lower mold14, inclined pins15, core elements16and slider17. In securing and supporting pre-forms4A,5A, a cylinder18is actuated to cause upward movement of the support block13and the main body part of the lower mold14, during which movement, core elements16and slider17are slid relatively outwards along inclined pins15. In this state, the pre-forms4A,5A are guided to preset sites. The support block13and the main body part of the lower mold14are then moved downwards, during which movement, core elements16and slider17are slid relatively inwards along the inclined pins15. In this state, the pre-forms4A,5A are supported and secured stably to define a cavity.
