  • Patent number: 8999214
    Abstract: In order for light conductor pins (6) in dead hole channels (5) of a plastic cover not to be melted together at their entire side walls with the cover they are produced through a particular injection molding tool in the same tool as the cover and the tool slide (104) which is a component of the injection molding tool (100) is aligned in the injection molding tool (100) with the dead hole channels (5) and inserted into the dead hole channels. The front plate is integrally molded with the base component before or after the light conductor pins are inserted into the base component. When the integral molding is performed after inserting the light conductor pins (6) the integral molding is also provided e.g. at a face of the inserted light conductor pins (6).

  • Patent number: 8999215
    Abstract: A cover that is assembled from a front assembly (3+6) and a base element (2) is produced in that the front assembly including the front plate (3) and the light conductor pin (6) are integrally injection molded in two subsequent injection molding steps, while the base element (2) is injection molded remote there from. Subsequently, the two components which are arranged in the different tool halves (101, 102) are brought in alignment with one another with an index plate (103) and are joined through closing the tool and are preferably interlocked with one another.
