射出成形用金型構造。 A first runner is formed along the separation surface of the pair of molds constituting the cavity, has a passage cross-sectional area that is substantially constant along the passage, is bent from the first runner, and is spaced apart from the separation surface of the mold. The injection mold structure is formed with a second runner extending to a gate provided at a position, and the mold on the side where the second runner is formed extends along the first runner and the second runner. The second runner and the groove for forming the gate are formed on the side surface, and in conjunction with the mold release operation of the molded product, the molded product is 1. A mold structure for injection molding, comprising a slide mold that slides in a direction in which the second runner and the groove for forming a gate are separated from each other.
