Claims

[Scope of utility model registration request]

In a resin molding die for molding a resin product having a substantially U-shaped cross section and an inwardly bent flange portion at the end, a core die body that forms a product molding portion between the cavity die and the cavity die is placed against the cavity die. A slide core for molding the end face of the flange portion is attached to the core die body so as to be slidable in a direction transverse to the approach and retraction direction, and a split cavity for molding the outer side of the end of the resin product is attached to the core die body so as to be movable toward and away from the resin product. An injection molding mold comprising an interlocking means that is attached to the slide core so as to be slidable in the same direction as the slide core, and that interlocks the slide core and the split cavity die after the split cavity die is separated from the resin product.
