Abstract
PURPOSE:To prevent the generation of an air pool at press forming time by burying a pipe in a concrete press die, releasing the end part opening of the pipe to the outside air from the side face of the press die, piercing a fine hole from the die forming face and communicating it to said pipe. CONSTITUTION:In case of the air remaining in the space formed by die forming faces 18, 19 at the press forming time of a work 3, the air can be exhausted to the outside air of a press die through fine holes 22, 32 and pipes 21, 31. So the work 3 is pressurized by closely fitting to the die forming faces 18, 19 of a die 30 and a punch 20 and can be press-formed in the specified shape. Also since the fine holes 22, 32 are communicated to the outside air via pipes 21, 31, the removing work of the work 3 after press processing can be facilitated.
