A removing device includes a fixture, an extendable and retractable arm, a heating rod, and a rotatable head. The fixture includes a top surface, a bottom surface, and a hole extending from the top surface to the bottom surface. The arm is threadedly engaged in the hole. The heating rod is coupled to an end of the arm. The heating rod includes a first portion inserted in the hole and coupled to the arm, and a second portion protruding from the bottom surface. The heater heats the heating rod. The rotatable head is rotatable relative to the fixture to move the heating rod between an extended position and a retracted position. In the extended position, the second portion heats the base material of the broken portion of a runner system. In a retracted position, the broken portion of the lens runner system is moved away from the injection mold.
