摘要
PURPOSE: An apparatus for elevating mother materials of a progressive mold is provided to form a concave channel on a surface of a backing plate on which a lower retainer is safely mounted and apply lubricant oil on the concave channel to reduce friction between the lower retainer and the backing plate, thereby preventing abrasion of components.;CONSTITUTION: An apparatus for elevating mother materials of a progressive mold includes a lower holder(10), an upper holder(60), a lifter(40), an elastic member, a fixing stripper(36), a guide fixture and a push punch. A lower retainer can move by the lower holder. The upper holder has an upper retainer in which a bending punch for bending a mother material is installed. The upper holder is above the lower holder. The lifter elevates a mother material. The elastic member provides an elastic force to the lifter in a direction of the upper holder. The elastic member is installed in the lower retainer.;COPYRIGHT KIPO 2010
