Abstract
In order to be able to produce packages economically and when the package design results in undercuts being provided in a deep-drawing tool for its manufacture, a simple and practical solution for the movement of the lower parts in each of the required work stations is advantageous. These lower parts are generally vertically movable in order to be able to easily open the mold. An inclined opening of the mold or rather removal of the lower part is achieved according to the invention in such a manner that between the lower part of the tool and the lifting device for facilitating its vertical movement there is provided a carriage guide which enables also an easy horizontal movement. A guide pin fastened on the carriage guide is part of a guide system which controls a desired forced inclined guided opening of the mold. The guide system can be used in deep-drawing tools, sealing tools and similar ones.
