Hydrostatic pressure pressurizing device that can uniformly pressurize by dry processing

摘要

PROBLEM TO BE SOLVED: To provide a hydrostatic pressure pressurizing device capable of precisely and evenly compressing from all directions as in a wet method while taking advantage of a dry method in which an object to be treated is not contaminated with a pressure medium in the hydrostatic pressure pressurizing method. do. SOLUTION: A molding mold of a pair of elastic materials to be fitted at a lower part and an upper part is fixedly installed on a main body 1 and a lid 2 of a high-pressure container, and an object to be processed is placed in a concave portion of a cylindrical lower molding mold with a bottom. Store. In the first step, the columnar upper molding die 7 is remotely inserted into the recess of the lower forming die 4 by a tapered guide mechanism as the lid is lowered, and in the second step, both are being lowered while the lid is lowered. The atmosphere in the space between the molding dies is vacuum exhausted so that the two molding dies are brought into close contact with each other without wrinkles. In the process, the entire inner surface of the upper molding die and the entire outer surface of the lower molding die are simultaneously pressurized with hydrostatic pressure by the same pressure medium entwined, thereby precisely compressing the object to be processed from all directions without directionality.
