  • the invention relates to a method for producing a plastic lining part with a visible and a rear side, which in at least two areas consists of at least two materials which differ in type, color, hardness, strength and / or surface quality.
  • the invention further relates to a lining part which is produced in particular by this method.
  • Lining parts of this type can only be produced with the known methods in a single working cycle if a plastic body only has to be molded onto the rear area of a prefabricated part.
  • the type of connection ie the assembly to the complete, ready-to-install lining part by gluing, stapling etc., is often decisive for whether the lining part and the method for its production are usable. It must also be taken into account that the expenditure in terms of production time, tools, devices and systems required for a complete lining part is relatively high.
  • achieving a stable connection often proves to be problematic.
  • the connection points can lead to weak points for the stability of the molded part as a whole.
  • the invention is based on the object of demonstrating a method for producing a lining part which is inexpensive and simple to carry out and which makes it possible to produce stable lining parts which meet the highest quality standards.
  • the invention is also based on the object of creating a lining part which is free from the disadvantages mentioned and in particular has a high stability and meets the highest quality requirements.
  • the production of the lining part made of plastic according to the method according to the invention ensures the production of a complete, installable lining part which, although it consists of at least two different materials in the visible and in the rear view area and in particular in the area of the transition or connection points of one on the other hand, the different areas are very stable and can be manufactured in a single work cycle.
  • plastic molding which are primarily variations of injection molding, for example swelling, injection molding, injection molding, cascade injection molding and hot runner injection molding, it is possible, apparently not materially with each other in terms of their properties connectable materials in one Combine work cycle to a homogeneous lining part that can form an independent assembly.
  • the method according to the invention makes it possible to attach a preformed part that has a dimensionally stable part, e.g. an injection molded part, a vacuum deep-drawn part or a non-plastic part, but also a part that is not inherently stable, e.g. can be a cut from film, textile, leather or similar material, in the rear area, including also to achieve sufficient dimensional stability of the preformed part, and to mold plastic on its edge area until the lining part is fully formed.
  • the invention also includes the possibility of using very different qualities of plastic, e.g. Expandable, fiber-reinforced or other colored plastic to be molded onto the preformed part.
  • the introduction of the plastic into the cavity of the injection mold is determined by the construction of the lining part to be produced.
  • the process according to the invention can be carried out by first introducing the molded part into a region of the cavity of the injection mold, which can be separated from another region by means of the separating element. It is subsequently adjusted and locked in the tool, preferably also by means of the separating element.
  • plastic is introduced into the region of the cavity delimited by the rear of the molded part. This is shaped until the final closing position of the tool is reached, for example in the swelling flow process.
  • the other area or the other areas of the plastic cavity until the complete molding of the lining part is injected, for example in the hot runner injection molding process.
  • the method according to the invention can also be carried out, for example, in such a way that a molded part is introduced into a region of the cavity and is preferably also adjusted and locked by means of the separating element, and that afterwards during a first phase, namely during the closing of the injection mold, Areas of the cavity plastic is introduced.

  • the preformed part can mainly consist of plastic. However, it can also consist predominantly or entirely of other materials.
  • the transition or connection point between the edge regions of the preformed part and the molded plastic is preferably designed in the form of a groove-like depression in order to have a stability-enhancing effect in the manner of a bead.
  • a strand-like, profiled molded part can be inserted into the groove-like depression of the transition or connection point, which forms a non-positive and / or positive connection with the materials, by means of which the transition or connection point between the edge regions is limited.
  • Such a molded part can combine aesthetics, functionality and stability. The latter is increased in particular when the molded part is equipped with reinforcement.
  • Another proposal of the invention has the content that in the lining part, which is e.g. is a door lining, reinforcement-like inserts are installed, which improve security, e.g. in the event of a side impact.

Furthermore, the lining part according to the invention can have recesses for subsequent assembly, e.g. of control fittings.

Abstract

Dans la cavité d'un moule pour moulage par injection, pouvant être subdivisée en plusieurs zones au moyen d'au moins un élément séparateur (9, 9'), une pièce prémoulée (2) est immobilisée dans une zone. La matière plastique est alors introduite dans le moule pour le moulage par injection qui ne se trouve pas encore en sa position de fermeture finale, ladite matière plastique prenant la forme de l'élément de revêtement, au moins dans la zone contenant la pièce prémoulée (2), jusqu'à ce que la position de fermeture finale soit atteinte dans la zone arrière de la pièce prémoulée. Par injection de matière plastique dans au moins une autre zone de la cavité, l'élément de revêtement est complètement formé en un seul cycle de travail. Cet élément de revêtement formé d'au moins deux zones de matériaux différents, peut être utilisé comme composant de revêtement pour l'intérieur des véhicules.
