Abstract
The invention relates to a screw compression spring embodied as an injection-molded part. The screw compression spring comprises a plurality of threads and planar end disks. An axial plane of the screw compression spring is oriented along the joint face of the injection mold. The sections of the threads adjacent to the joint face are less inclined than the thread pitch at least on one side.
Claims4
Screw compression spring configured as an injection-molded part, having several windings and having planar end disks, whereby an axial plane of the screw compression spring is oriented in the parting plane of the injection mold, characterized in that the sections (5) of the windings (2) that are adjacent to the parting plane (4) demonstrate a lesser incline than the winding pitch, at least on one side.
