Title:
HYDRAULIC PRESSURE MOLDING DEVICE AND HYDRAULIC PRESSURE MOLDING METHOD
Document Type and Number:
WIPO Patent Application WO/2005/021178
Kind Code:
A1
Abstract:
A hydraulic pressure molding device (A) and a hydraulic pressure molding method for molding a molded body of a specified shape by holding a material plate (1) by a first mold (10) pressing the material plate (1) with a pressurized liquid medium (2) and a second mold (20) in which a molding recessed surface (21) of a specified shape is formed and pressing the material plate (1) with the liquid medium (2) to bring the material plate (1) into contact with the molding recessed surface (21). The second mold (20) comprises deformation resistance adjusting means (22) and (23) locally differentiating the deformation resistance of the material plate (1). The deformation resistance adjusting means (22) and (23) are formed of a local cooling means (22) locally cooling the material plate (1) and a local heating means (23) locally heating the material plate (1). In addition, the deformation resistance adjusting means (22) and (23) are formed movable forward and backward relative to the second mold (20).
