Provided is an injection mold capable of forming and blowing out a hollow plastic product such as a pipe and a cylinder. The injection mold forms the outer surface of a hollow product which has a face-to-face contact surfaces and a cavity therebetween and includes an upper core mounted on and fixated to an upper disk; a lower core mounted on and fixated to a lower disk; at least one slide core, which has a core block moving between a first location, inserted into a cavity to form the inner surface of a product being inject-molded and a second location out of the cavity; a through hole making the core block penetrating therethrough; and stoppers with the same number as the number of the slide cores to prevent the movement of the product being inject-molded along the core block moving from the first location to the second location by being pressed against one side of the upper core and the lower core when the core block is at the first location. |
