Problems solved by technology

The use of cutting tools is a disadvantage in this process because, on the one hand, wear of the knives occurs and, when incorrect cuts or ragged tears occur, lead to an increased reject rate; on the other hand, Performing the above operations on foaming tools results in wasted time and increases the risk of operator injury

Embodiment Construction

[0026] figure 1 A cross-section of the molded skin 1 into which pre-weakening has been introduced is shown. The molded skin 1 is elastic and can be produced by the rotational sintering method or the slush molding method, but it can also be cast, deep-drawn or sprayed. The molded skin 1 in this embodiment consists of polyvinyl chloride or other thermoforming material, or comprises one of these materials. The thickness of the molded skin 1 in this embodiment is 1.2 mm. The grooves 4a and 4b are V-shaped in this embodiment, but may be of other shapes, such as rectangular or semicircular. The grooves 4a and 4b are spatially separated from each other and not connected to each other; however, the molded skin 1 can also have a through groove. The pre-weakening, i.e. the remaining thickness of the molded skin 1 at the grooves 4a and 4b, is in this embodiment identical, i.e. between 0.4 mm and 0.6 mm depending on the manufacturing method used; however, these Grooves can also have ...

Abstract

The invention relates to a method for producing an interior part in a foaming tool, correspondingly to a produced interior part, and to a foaming tool which can be used for producing the interior part. The interior trim comprises at least one molded skin (1), at least one foam layer and at least one carrier (5), and the foam layer is placed between the molded skin (1) and the carrier (5). According to the invention, in order to produce an inner lining, the molded skin (1) is introduced into the mold (7) of the foaming tool. The foaming tool contains at least one separating edge (8). During backfoaming, the carrier (5) is pressed against the molded skin (1) at the separating edge (8) and connected to said molded skin so that the molded skin residue (2) The molded skin ( 1 ) can be detached manually, ie without the aid of tools, or the molded skin residue ( 2 ) may have been detached during extrusion.

Description

technical field [0001] The invention relates to a method for producing an interior part in a foaming tool, a correspondingly produced interior part, and a foaming tool for producing said interior part. Background technique [0002] Interior parts installed in motor vehicles can be produced using different processes. The interior part has a molded skin which, after installation of the interior part, faces the passenger compartment of the motor vehicle, which is connected to a carrier and is foamed on the back. Molded skins, which can be produced eg by a sintering process, in this case also called slush-molded skins, are inserted into a foaming tool and pressed together with the carrier during back foaming. Due to the larger dimensions of the molded skin than the carrier, a part of the molded skin, the so-called molded skin residue or slush molded skin residue, will remain protruding outside the carrier. This remnant must be cut from the molded skin before the further use of...
