Definitions
- the invention relates to a method for producing a heterogeneous, in particular multi-colored sheet, for example, a decorative skin for an interior trim part of a vehicle, as well as suitable tools and fabrics produced therewith.
- a method for producing a heterogeneous but one-piece molded part is known, the region of a hard, thermoplastic material, such as polypropylene (PP) or a PP compound, and an elastically deformable material, such as a thermoplastic Elastomer on an olefinic basis.
- the first and the second molding segment are made in separate tools and subsequently joined by the injection molding of a connection segment to form a unit.
- This method is suitable for the production of small-sized molded parts with complex geometry and high-quality appearance, but lends itself to the production of large and areal components, especially decorative skins for interior trim parts, due to the complex handling of the extended component segments less.
- the object of the invention is to provide a process for producing high-quality and heterogeneous, in particular at least two-colored, fabrics.
- the object is achieved in that in this method, at least a first cavity and a second cavity of a tool with at least a first and a second, flowable and after removal of a one-piece sheet plastic material are filled, at least when filling a cavity a along the parting plane to the adjacent cavity extending sealing element is arranged in the tool.
- a suitable tool for carrying out the method has at least one first tool part and a second tool part which can be displaced relative thereto, which form at least one first cavity and an adjacent second cavity after closure of the tool, which can be filled with at least one first and one second flowable plastic material ,
- a sealing element is arranged along the dividing plane between the first cavity and the second cavity.
- the following embodiments of the method can be used with particular advantage when using reactive curing plastic materials which are injected into the cavities by means of an injection molding process (Reaction Injection Molding (RIM)).
- RIM Reaction Injection Molding
- These plastics have a particularly low viscosity in a flowable state, so that the sealing between the cavities has an extraordinary importance.
- the sealing element is firmly connected to a tool part, in particular the upper tool, and to another tool part, in particular the lower tool, can be pressed.
- the sealing element under fluid pressure expandable (“inflatable seal") and to a projecting projection of the other tool part, in particular of the lower tool, can be pressed.
- the sealing element After filling the first cavity with the first plastic material, the sealing element can be lifted from the other tool part and the second cavity filled with the second plastic material, wherein the first and the second plastic material cohesively, but optically cleanly separated, connect together.
- the lifting of the seal is preferably done by reducing the fluid pressure inside the tube-like seal, wherein a fluid pressure is adjustable below the ambient pressure is. As a result, a lift-off force is generated, which goes beyond the elastic return of the sealing element.
- the sealing element is preferably fixedly arranged in a tool part, in particular the upper tool, and can be expanded under fluid pressure to be pressed against the other tool part, in particular the lower tool.
- the sealing element before filling the cavities in the region of the parting plane releasably inserted into a tool part, in particular the upper tool, and when closing the tool sealingly applied to the other tool part, in particular the lower tool.
- the sealing element on a projecting projection of the other tool part, in particular of the lower tool can be pressed and connects during filling of the cavities cohesively with the first plastic material on the one hand and the second plastic material on the other.
- the sealing element is thus lost in the production of the molded skin and must be replaced by a new sealing element before refilling the cavities.
- the sealing element is releasably in a tool part, in particular the upper tool, used and to the other tool part, in particular the lower tool, can be pressed.
- FIG. 2a-e tool and method according to another embodiment of the invention are identical to Fig. 2a-e tool and method according to another embodiment of the invention.
- the tool 1 shown in Fig. 1a to 1d consists of a first tool part 2 in the form of the upper tool 3 and a second tool part 2 'forming lower tool 4th upper tool 3 and lower tool 4 are mutually displaceable and form in their position of use according to Fig. 1 a a first cavity 5 and a second cavity 5 '.
- the two-dimensionally extending cavities can be filled with different flowable plastic materials via injection molding units, not shown, and are suitable for the production of fabrics which have a very small thickness in relation to their length and width.
- the cavities need not be flat, but may also have a curved course for the production of complex shaped decorative skins.
- the upper tool 3 is provided along the dividing plane 6 between the adjacent cavities 5, 5 'with a tubular sealing element 7, whose cavity 8 can be filled after closing the tool parts 2, 2' with a pressurized gas.
- the sealing element 7 is fixedly connected to the upper tool part 3 by means of a holder 9 fixed by means of screws 9.
- the sealing element 7, whose longitudinal extension can also have a complex course expands elastically and seals against a projection 11 projecting from the lower tool 4.
- the first cavity 5, as shown in Fig. 1 b with a thin first, for example filled gray plastic material 12, which is prevented by the sealing element 7 at a transition into the second cavity 5 'and cured as a result of a chemical reaction in the first cavity 5.
- the cavity 8 of the sealing element 7 is subjected to negative pressure, so that the sealing element 7 lifts off from the projection 11 (FIG. 1c).
- the second, for example, black plastic material 12 ' which is subsequently injected into the second cavity 5', penetrates as far as the first plastic material 12 and, in the case of reactive curing, bonds to it in a materially cohesive manner. After opening the tool 1 (FIG. 1f), the two-color fabric 13 thus obtained can be removed.
- the tool according to FIG. 2 a provided for carrying out another method according to the invention likewise has two tool parts 2, 2 'in the form of an upper tool 3 and a lower tool 4, wherein the lower tool 4 is likewise provided with a projection 11.
- the upper tool On its side facing the projection 11, the upper tool is equipped with a groove-like receptacle 14 for the clamping, but detachable mounting of a strand-shaped, elastic sealing element 7 (FIG. 2b).
- the one-piece sheet 13 including the lost sealing element 7 can be removed.
- the Sheet 13 in the region of the parting plane 6 naturally have another, determined by the sealing element 7 color.
