Abstract
A molding tool for producing several assembly injection molded components, especially assembly injection molded switching dampers, which are combined into a subassembly by inserting an insertion part, and a method for producing such a subassembly from several components using the molding tool of the invention. The insertion part is encapsulated at least partially by one or more of the components to be injection molded, as a result of which a completely assembled subassembly is produced in the original molding process. This can be, for example, a switching damper assembly , which results from a common actuating shaft . In this way, assembly injection molded components with a complicated structure can be produced, for which a molding tool with only a single molding cavity would not be usable. The individual components are produced in different mold cavities, which preferably are mounted rotatably on a carousel. By rotating the mold cavities, their accessibility to handling tools, which are needed for the production steps, can be determined flexibly.
