Device for removing broken runner system from injection mold

A removing device comprising:

• a fixture comprising a top surface and a bottom surface opposite to the top surface, and defining a hole extending from the top surface to the bottom surface;
• an extendable and retractable arm threadedly engaged in the hole of the fixture;
• a heating rod coupled to an end of the arm, the heating rod comprising a first portion inserted in the hole and coupled to the arm, and a second portion protruding from the bottom surface;
• a heater coupled to the heating rod, the heater being configured for heating the heating rod;
• and
• a rotatable head coupled to another end of the arm distant from the heating rod and protruding from the top surface of the fixture, the rotatable head capable of rotating relative to the fixture to move the heating rod between an extended position where the second portion of the heating rod heats a base material of a broken portion of a runner system, the broken portion of the runner system being received in a sprue of an injection mold, the heated base material being solidified to engage with the second portion, and a retracted position where the broken portion of the runner system is moved away from the injection mold.
