[0027] The technical problem of the present application is effectively solved by providing a vertical stamping powder forming device. When the stamping is completed, the powder formed inside the female die is tightly attached to the inside of the female die under the pressure of the hydraulic system, making it difficult to remove. In use, the first lifting frame slides downward under the push of the hydraulic cylinder, so that the female die is sleeved on the stamping die plate of the lower male die. The stamping die plate of the lower male die will block the bottom end of the female die. Then the powder is poured into the inside of the female die. Then the first lifting frame and the second lifting frame slide upward under the drive of the hydraulic cylinder, so that the stamping die plate of the upper male die can be inserted into the inside of the female die from above. Under the action of the pressure of the hydraulic cylinder, the powder inside the female die will be stamped and formed. Then the second lifting frame slides downward under the pull of the hydraulic cylinder to reset, so that the stamping die plate of the lower male die can be separated from the female die. At this time, the bottom end of the female die will be opened. Then the first lifting frame continues to be pulled upward by the hydraulic cylinder. At this time, the upper male die slides downward relative to the female die. The stamping die plate of the upper male die will push the powder formed inside the female die out during the downward sliding process, achieving the effect of facilitating demolding.
