Problems solved by technology

[0003] This method is suitable for the production of small molded parts with complex geometries and high-value (high-value) appearance, and is not suitable for the production of large sheet-like structural parts, especially decorative skins for interior decoration parts, because they are difficult. Manipulate extensions of such structural components

Embodiment Construction

[0018] Figures 1a to 1d The mold 1 shown comprises a first mold part 2 formed by an upper mold 3 and a second mold part 2' formed by a lower mold 4. The upper mold 3 and the lower mold 4 can be displaced relative to each other, and when they are located Figure 1a In the shown use position, a first cavity 5 and a second cavity 5' are formed. These cavities extending in two dimensions can be filled with different free-flowing polymeric materials by means of an injection molding unit (not shown) and are suitable for the manufacture of sheet-like structures which have, relative to their length and width, Very small thickness. The cavity does not have to be formed in a planar manner, but can have a curved profile for making a complex shaped decorative skin.

[0019] The upper mold 3 is provided with a tubular sealing member 7 along the interface 6 between adjacent cavities 5, 5', wherein the hollow space 8 can be filled with compressed gas after the mold parts 2, 2' are closed....

Abstract

The invention relates to a method for producing a heterogeneous, especially multi-coloured structure (13), for example a decorative skin for an inner lining part of a vehicle. According to said method, at least one first cavity (5) and one second cavity (5') of a tool (1) are filled with at least one first and one second flowable plastic material (12, 12'), said plastic material forming a single-component structure once it has been removed. A sealing element (7) extending along the separating plane (6) to the adjacent cavity is arranged in the tool (1) at least during the filling of a cavity.

Description

technical field [0001] The invention relates to a method for producing inhomogeneous, in particular polychromatic, sheet-like structures, such as decorative skins for vehicle interior trim parts, as well as to molds suitable for this purpose and to the resulting Sheet structure. Background technique [0002] Patent application DE 102 11 663 A1 discloses a method for producing inhomogeneous but one-piece moldings, wherein the moldings comprise in certain parts a hard thermoplastic material such as polypropylene (PP) or PP compounds, and an elastically deformable material such as olefin-based thermoplastic elastomers. The first and second parts of the molded article are produced in separate moulds, and subsequently combined to form a single body by molding over a coupling part. [0003] This method is suitable for the production of small molded parts with complex geometries and high-value (high-value) appearance, and is not suitable for the production of large sheet-like str...
