A forming mold for an oil injection hole-protecting structure is provided to perform a fabricating process of the oil injection hole-protecting structure smoothly by allowing a fabricator to simply move an oil injection hole-forming part and substantially reducing a time that is taken to move the oil injection hole-forming part. A forming mold for an oil injection hole-protecting structure comprises: an upper mold(100) which is positioned in the mold, has clamping grooves(111) formed on one side of a bottom face thereof, and forms an upper part of the oil injection hole-protecting structure; a core mold(200) which is positioned below the upper mold, and in which clamping holes(211) are formed correspondingly to the clamping grooves, the core mold including an inner forming part(220) for forming an inner side portion of the oil injection hole-protecting structure, an oil injection hole-forming part(221) for forming an oil injection hole in the oil injection hole-protecting structure, and a cylinder(230) connected to one side of the oil injection hole-forming part to straightly move the oil injection hole-forming part such that the oil injection hole-forming part forms the oil injection hole in the oil injection hole-protecting structure; and a lower mold(300) including clamping rods(311) correspondingly positioned below the core mold and drawn into the clamping holes of the core mold and the clamping grooves of the upper mold to form a lower part of the oil injection hole-protecting structure.
