ABSTRACT:
An injection molding system for forming a molded plastic part including a die having a pair of die halves which mate along their joining surfaces to form a parting line and define a mold cavity, a plurality of ejection pins within at least one of the die halves and operable to move the finished molded part in a direction away from at least one of the die halves, a gate removably mounted to one of the die halves, and a runner. The gate includes an inlet and an outlet having an edge surface extending in a direction generally opposite to the movement of the molded part upon ejection from the mold cavity. Upon separation of the two die halves, the ejection pins are then further operable to remove excess cooled plastic material from the gate and the runner.
