CONSTITUTION: In the parting method of the mold of pushing out to part the formed product 40 from a movable mold 12 through push-out pins 22 by abutting the push-out plate 20 having fixed push-out pins 22 on plural pieces of hitting rods 20 with the shifting of the movable mold 12, before abutting the push-out plate 20 on plural pieces of hitting rods 30, the projecting length of each hitting rod 30 is controlled so that the distances between the tip parts of respective hitting rods 30 and the push-out plate 20 are almost equal with each other.
