Abstract

A molding tool and method for producing an interior trim part. A cavity is embodied between a first element and a second element, and a slide is displaceably connected to the first element. A decorative layer is arranged on the first element and a backing is arranged on the second element. A foamable mixture is added to the hollow area between the backing and a reverse side of the decorative layer, such that a foam layer fills the hollow area. A distance between the first element and the second element is increased to enlarge the hollow area. During this process, the slide is pressed against a side facing away from the reverse side of the decorative layer, such that the hollow area is sealed with the reverse side of the decorative layer pressed against a lateral surface of the backing and/or against a lateral surface of the second element.
