Method for producing a cover

摘要

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.

1. A method for producing a cover made from injection molded plastic material including:
a front plate (3) and at least one light conductor pin (6) from light permeable plastic material integrally connected therewith in one piece, wherein the light conductor pin extends from a front side of the front plate (3) through the front plate and beyond the backside of the front plate; a base element (2) made from non-light permeable plastic material which extends from the backside of the front plate (3) towards the back about the at least one light conductor pin (6), wherein the method comprises the following steps sequentially performed through an injection molding tool 100:
a) the front plate (3) and the at least one light conductor pin (6) are directly molded together in the same tool in a single injection molding step or in two injection molding steps occurring after one another;b) the base element (2) is injection molded remote from a front assembly (3+6) including the front plate (3) and the light conductor pins (6) in the same tool (100);c) after opening the tool (100), either the base element (2) or the front assembly (3+6) is axially moved out of the rest of the tool through a movable tool component (103);d) the tool component (103) with the base element (2) or the front assembly (3+6) axially moved out is moved transversally so that the base element (2) is in an aligned position with the at least one light conductor pin (6);e) the tool (100) is closed and thus the base element (2) with its at least one channel (5) is pushed over the at least one light conductor pin (6) in a direction towards the front plate (3) and interlocked with the front plate (3) on the backside of the front plate (3); andf) after opening the tool (100) the cover (1) is removed.
