造。 In an injection mold in which a cavity for injection molding is formed by a movable mold, a fixed mold, and a sliding core, a core guide hole is provided in the fixed mold, and the core is slidable into the core guide hole. The slide core is provided with an undercut on a surface forming the cavity, the slide core is provided with an inclined guide hole that is inclined in a direction receding from the cavity, and the inclined guide hole has a tip. means for inserting a rod into the fixed mold and driving the inclined guide rod forward and backward in a direction orthogonal to the core guide hole through the fixed mold, and forming a bumper surface on the movable mold, The mold is clamped to the fixed mold, and the sliding core is moved to form a part of the cavity by sliding of the inclined guide rod, and injection molding is performed with the cotter hitting the cotter surface. An injection mold structure that is characterized by
