Dry-method compression molding method and equipment for sagger and sagger

The invention discloses a dry-method compression molding method for a sagger. The dry-method compression molding method comprises the following steps of: distributing sagger powder into a mold cavity formed by a mold frame, a bottom lower mold core and a side lower mold according to a pre-set height; dividing the sagger powder located above the bottom lower mold core and the side lower mold into a bottom powder aggregate and a side edge powder aggregate by the bottom lower mold core and the side lower mold; pressing an upper mold core to the upper surface of the mold cavity; jacking the side lower mold to the pre-set height to form a pre-pressed blank body; pressing the upper mold core to the mold cavity and keeping the bottom lower mold core and the side lower mold still; and pressing the pre-pressed blank body through the upper mold core to form the sagger. Correspondingly, the invention further discloses dry-method compression molding equipment for the sagger and the sagger. With the adoption of the dry-me
