Abstract
A mold protecting system for an injection molding machine includes a voltage source, a controller, a first mold, a second mold, a fixed platen, and a movable platen. The first mold is fixed to the movable platen. The second mold is fixed to the fixed platen. The controller from the voltage source to charge the first and second molds, and detects the capacitance between the first and second molds when the distance between the first and second molds equals a pre-set value. If the capacitance between the first and second molds is greater than a reference value, the controller controls the movable platen to stop moving.
