<p>PURPOSE: An injection molding device is provided to easily perform a wire to supply electricity to a coil as the coil is not moved with the operation of a linear motor. CONSTITUTION: An injection molding device comprises a current supplying unit and a control unit. After the control unit controls a process for the magnetization and the demagnetization of cores of electromagnets, the process is controlled with a second current pattern in predetermined times. Direct currents, which are supplied to the coil in the demagnetization process in the last of a first current pattern and the second current pattern, have reverse directions.
