Ejection mechanism of injection mold

The utility model discloses a mechanism on an injection mold, in particular to an ejection mechanism of the injection mold, which comprises a wedge rod, a wedge block, a spring I and a spring II, and the spring II is sleeved on a guide post and is abutted between a fixed mold core and an ejection plate; the wedge block and the first spring are both located in a sliding groove of the ejection fixing plate. One end of the wedge rod extends to the wedge block until the inclined surfaces of the wedge rod and the wedge block abut against each other, the wedge rod moves away from the movable mold to drive the wedge block in the sliding groove to compress the first spring, meanwhile, the protruding part on the wedge block is embedded into the groove part of the ejector plate, and the second spring is reset synchronously; on the contrary, the ejector plate moves towards the movable mold, the wedge block is driven to move in the sliding groove through the reset acting force of the first spring after the protruding par
