SEMISOLIDIFIED METAL PRODUCT MOLDING DIE STRUCTURE, METHOD OF MOLDING SEMISOLIDIFIED METAL PRODUCT, AND SEMISOLIDIFIED METAL PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a semisolidified metal product molding die structure that attains assured molding of a product with a complex configuration, such as a thin product with flange part, from a high-quality semisolidified metal at low cost, and also to provide a relevant molding method and a semisolidified metal product.;SOLUTION: The semisolidified metal product molding die structure includes a fixed lower die designed to mount the semisolidified metal on its upper surface side and a movable upper die capable of descending for pressurization toward the fixed lower die. Further, the structure includes a side die disposed on the side portion of the fixed lower die and adapted so as to form a product cavity together with the fixed lower die and the movable upper die. The side die is provided on the fixed lower die in a vertically slidable manner and is capable of ascending for pressurization with a force smaller than the descending pressurization force of the movable upper die. The compression of the upper die is started at a position where the side die is ascended, and the compression is maintained while defining the peripheral side portion of the product and then final molding is performed at the lowest position.;COPYRIGHT: (C)2009,JPO&INPIT
