Zusammenfassung:	Disclosed are injection molds and methods for using the same. Some injection molds include two or more mold portions, each having a molding surface, the mold portions being movable relative to one another between an open state and a closed state in which the molding surfaces of the mold portions cooperate to define a mold cavity, an injection conduit configured to convey injection molding material to the mold cavity, and a de-gating device coupled to at least one of the mold portions, the de-gating device having a blade and an actuator coupled to the blade and configured to move the blade relative to the at least one mold portion between a retracted position and an extended position in which a cross-sectional area of a portion of the injection conduit is reduced relative to when the blade is in the retracted position.
