A releasing device for an injection mold is provided to quickly and stably release a molded product by making a push rod rotate by 90 degrees simultaneously with opening of the mold and push the molded product. An injection mold includes a fixed mold(1) having an inner mold, a movable mold(2) having a bottom mold(21), and a core mold(3) assembled to the movable mold such that the core mold forms an outer wall of a molded product by being transferred by a hydraulic cylinder along a guide pin. The fixed mold has both sides with a releasing device(100) for automatically releasing the molded product. The releasing device includes a cylinder(4), an inverse L-shaped bracket(5), and a rotating cylinder(7). The cylinder has a predetermined stroke. The inverse L-shaped bracket is mounted on a front end of the cylinder. The rotating cylinder is mounted on a side wall of the bracket, and smoothly guides release of the molded product by rotating a push rod(6) by 90 degrees through a stopper(8).
