PROBLEM TO BE SOLVED: To provide an injection mold which enables an injection-molded product to be removed from a slide core without impairing the injection-molded product when the mold is opened. SOLUTION: The injection mold is structured of a cavity side 3, a movable part 5 corresponding to the cavity side 3 and a slide core 7 which is fitted to the movable part 5, and has a first, a second and a third core constituent part 71, 72 and 73 arranged adjacent to each other in such a way that the parts 71, 72 and 73 can slide independently of each other. In addition, the second core constituent part 72 is made to slide in a direction where it is separated from an injection-molded product 100 earlier than the first and the third core constituent part 71 and 73 with the help of an adopted slide timing control mechanism, when the mold is opened.
