Abstract:
A mold for forging a scroll rotor capable of controlling material flow speed by adjusting a land section, a molding device applying same, and a method for manufacturing the mold. In the mold, a die includes an extrusion unit having a molding space therein and a spiral-shaped extrusion passage provided in the lower portion thereof so as to correspond to a wrap portion disposed in the scroll rotor. A punch is connected to the die to be in close contact with the inner circumference of the molding space and to be able to slide up and down. The lower portion has a shape corresponding to the upper surface of the flange portion of the scroll rotor and a boss portion. The extrusion passage has a land section in direct contact with the extrusion material. The height of a land of the land section varies along the spiral direction.
