A separating system for separating or separating items formed in a cavity of an injection molding system to separate them from material in the mold's runner, has a clamp plate for anchoring the separator system. The clamp plate secures a separating plate that supports a first separating pin, either directly or via an actuator. The first separating pin includes a base, a body having a cross-sectional portion, a neck having a cross-sectional portion, and a wedge-shaped tip. The system includes a support plate that supports a cavity plate, where the cavity plate has a first cavity and a first gate that fluidly couples the first cavity to a first runner channel. The separating first separating pin can be articulated to separate a molded material at a boundary between the first gate and the first cavity.
