Abstract
A molding tool is provided for producing hot-formed components, in particular formed sheet metal parts. The molding tool includes a tool lower part and a tool upper part which are movable in relation to each other, and which include corresponding operative faces for shaping a hot-formed component. The operative face of at least one of the tool parts is configured so as to be coolable and that tool part includes cooling lines therein. At least one of the tool parts includes a clearance which in a closed state of the molding tool, conjointly with the hot-formed component, forms an air chamber. The air chamber functions as a thermal insulator between the hot-formed component and the tool part.
