PURPOSE: A magnet fixture for preventing grooves on the surface of a fixed mold and an insert injection mold using the same are provided to increase the intensity of magnetic force by minimizing the number of grooves on the surface of a cavity. CONSTITUTION: A mold(10) for insert injection comprises a movable mold(3), a fixed mold(5), and a metal rod(30). An insert metal plate(17) is installed on the fixed mold. A plurality of magnets(12) is attached to the metal rod. The metal rod is installed in the fixed mold. The upper surface of the metal rod is correspondently mounted to a cavity surface(16) of the fixed mold.
