Document Type and Number:
WIPO Patent Application WO/2015/178267
Kind Code:
A1
Abstract:
In the present invention, a press molding method includes: a first step for determining a pressing force that a material to be molded exerts on each part of a metal mold during press molding, such determination carried out while press molding the material to be molded by individually driving each part of the metal mold divided into a plurality of pieces; and a second step for adjusting, for each part of the metal mold, at least one of an applied driving force, driving speed, and driving timing so that processing portions of the material to be molded, detected to be approaching an overload state on the basis of the pressing force, are caused to flow into other processing portions of the material to be molded.
