1. A method for producing a foam-mold part comprising the steps of:
providing a sealing shell for partially bounding and for sealing a cavity, the sealing shell comprising a foam mold side and a tool carrier side, wherein the sealing shell is made of a material that is compressed when the cavity is closed and the sealing shell is manufactured from a material comprising a polyolefin; introducing the sealing shell into a tool carrier half, wherein a receiving device of the tool carrier half comprises vacuum perforations; forming, via the sealing shell, a large surface, three-dimensional delimitation for a foam introduced into the cavity; affixing the sealing shell in the tool carrier half with a vacuum generated by a vacuum pump through the vacuum perforations in the tool carrier half; and in order to form a sealed cavity; pressing a counterpart of the sealing shell onto the sealing shell, and, before or after pressing-on; introducing a foam into the cavity so that the sealed cavity forms and the foam introduced into the cavity expands only within the cavity; wherein the forming and expanding comprises the steps of; applying a polyurethane-based coating to the sealing shell on a cavity side before producing the foam-molded part; introducing the foam into the cavity; pressing a plastic carrier at a defined force F into the sealing shell, thereby elastically deforming a contact edge of the sealing shell with a contact edge of the plastic carrier; forming a contact contour at a plurality of contact points by this process; expanding the previously introduced foam in the cavity; imparting a shape of the cavity to the foam during a foaming of the previously introduced foam; de-molding the foam-molded part comprising the plastic carrier, the foamed foam and the coated coating after completion of the foaming and without the use of a release agent. |
