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).
Claims10
A method for producing a cover from injection molded plastic material, the cover comprising:
- an integrally connected base element and front plate;
- at least one base element dead hole channel each open on a backside of the base element;
- and
- at least one light conductor pin made from light permeable plastic material, each of the at least one light conductor pin arranged in a respective dead hole channel,
- wherein the method comprises the following steps:
- injection molding the base element in an injection molding tool, the injection molded base element remaining in the injection molding tool;
- injection molding light conductor pins in an index plate of the injection molding tool remote from the remaining base element;
- arranging each injection molded pin so as to align with a respective dead hole channel of the remaining base element by opening the injection molding tool and moving each pin out of the injection molding tool and about an axial direction using the index plate;
- closing the injection molding tool and axially inserting each aligned pin into its respective dead hole channel using an axially movable tool slide;
- directly integrally molding the front plate onto the remaining base element in the injection molding tool before or after said arranging of the light conductor pins;
- and
- opening the injection molding tool and removing the cover.
