LOAD APPLYING DEVICE, PRESS-FORMING DIE, AND PRESS-MOLDING METHOD

摘要

The present invention provides a load applying device for a press-molding die, the load applying device being provided with: a rod which has a first end part, a second end part, and a flange; a stacked disc spring which is formed by stacking a plurality of disc springs having a center hole into which the first end part of the rod is inserted; a first plate having a first through hole into which the first end part of the rod is inserted and for coming into contact with the stacked disc spring; a second plate having a second through hole into which the second end part of the rod is inserted and for coming into contact with the flange; and a space securing part which is disposed between the first plate and the second plate in a detachable manner and which ensures that a space is formed between the first plate and second plate so that the space needed for the stacked disc spring to impel the flange toward the second plate is maintained. The second end part and the first plate move relative to one another in the direction in which the second end part and the first plate come into close contact with one another during press molding, thereby compressing the stacked disc spring.
