Plastic mold component for engine of motor car, has abutment and support surfaces that are connected such that distance between edge portion and hinge axis is set lesser than distance between end edge region and hinge axis

摘要

The mold component (1) has a flap portion (2) provided with a hinge element (3). An abutment surface (6) is connected with a support surface (7) at the closing state of the flap portion such that the distance between an edge portion (10) of a retaining surface (11) and a hinge axis (5) is set lesser than the distance between an end edge region (9) and the hinge axis. The distance between the retaining surface and the abutment surface is set larger than the distance between the end edge region and the supporting surface with increasing distance from the hinge axis.
