Claims

[Scope of utility model registration request]

In an injection mold for molding a resin product having a substantially U-shaped longitudinal section and a flange portion bent inward at at least one end, a core die main body portion that forms a product molding portion between it and a cavity die. is installed to be able to move toward and away from the cavity die, and a slide core having a molding surface for molding the inner surface of the flange portion is slidably attached to the core die body along an inclined surface formed in the core die body. An injection molding mold comprising: a split cavity die having a molding surface for molding the outer surface and end portion of the flange portion; and attached to the core die main body portion so as to be slidable toward the outside of the resin product.
