The utility model discloses a vertical mold frame for powder forming. The device comprises an upper punch fixing seat, a pattern die fixing seat and a lower die fixing seat, the upper punch fixing seat is connected with the swage die fixing seat through an upper guide pillar; the lower die fixing seat is connected with the swage die fixing seat through a lower guide pillar; the upper punch fixingbase comprises an upper cross beam, a T-shaped block connector and a stress leveler. The T-shaped block connector is composed of two L-shaped metal plates, and the two L-shaped metal plates are installed in the middle of the upper end face of the upper cross beam in a bilateral symmetry mode and used for limiting and fixing a T-shaped block. The stress balancer is installed in a groove located inthe middle of the upper end face of the upper cross beam, the upper end face of a balance block in the stress balancer makes contact with the end face of a T-shaped block, and the upper end face of the balance block slightly floats out of the upper end face of the upper cross beam. By means of the mode, force exerted on the upper cross beam by the T-shaped block can be kept uniform, so that damageto a die frame and a die can be avoided, the service life of the die frame and the die is prolonged, and product machining quality is improved.
