Embodiment Construction

[0017] FIG. 1 shows in detail a part of a metal lining which has not yet been three-dimensionally deformed, which is a flat structure and is made of a steel sheet. Holes 2, ie through-holes, are machined in this steel sheet in a special manner, in such a way that the metal lining 1 has a sieve-like structure. The metal lining 1 resembles a kitchen cot and has a profiled outside, namely the pouring side 4, and a smooth inside 6 on which there are only through-hole openings.

[0018] Protruding from the outer casting side 4 are projections 3 punched out of the metal sheet of the metal lining 1 , which have approximately the shape of a quarter-shaped hollow sphere. As a result, the projection 3 has the shape of an open shell, wherein the half-shell opening 8 on the pouring side 4 forms the opening of the through-hole 2 . The opening planes of the holes 2 on the pouring side 4 are approximately perpendicular to the base surface of the metal backing 1 , wherein the planes of the o...

Abstract

A lightweight, plastic coated component is in the shape of a three-dimensional shaped part with a metal layer provided with access apertures through which the plastic may flow. The component includes stiffening ribs created by the plastic that are positioned within hollow areas of the three-dimensional shaped part, and whose plastic extends through the apertures of the metal insert. The component is formed as a metal insert spray-covered with plastic for the purposes of optimizing the plastic spray process and to achieve an inner bond between the metal insert and the stiffening ribs. The metal insert includes a large number of evenly-distributed holes, and these holes form a flow resistance and also a flow enabler for the molten mass of plastic during spraying. There are projections present at each of the holes that are covered by the plastic coating. The stiffening ribs facing away from the sprayed side have a connecting cross-section that extends into the metal insert via a number, or a large number, of holes in the metal insert.

Description

technical field [0001] The invention relates to a lightweight structural element. Background technique [0002] Such a lightweight structural part is known from DE 38 39 855 C2. The substantially closed-wall metal layer of such a lightweight structural component consists of a shaped body made of sheet metal with large-sized holes arranged at a defined distance from one another. The reinforcing ribs made of injection-molded plastic arranged in the hollow region of the shaped body are aligned with the holes through which the plastic is passed in the shaped body in order to seal off the edge of the holes. In this way, discontinuous connection points are formed for the reinforcing ribs in the shaped body at which a form-locking connection is formed between the plastic of the reinforcing rib and the metal of the shaped body in each case. [0003] In the known lightweight structural parts, the shaped body made of sheet metal has a considerable rigidity, while it, as a so-called ...
