Definitions

  • the invention relates to a method for producing a molded part made of plastic, which is covered at least on one side with a material, preferably a trim part for the interior of a motor vehicle.
  • the invention further relates to the molded part itself.
  • the part serving as the carrier plate is first produced today; the fabric used as decor is then laminated on, as well as energy-absorbing upholstery parts made of foams such as PU, EPP, EPS / PPO mixtures and connecting elements such as Retainer / clips made of plastic glued on.
  • the material for the carrier part is mostly wood flour polypropylene (HMPP), cotton fiber or plastic injection molding (a material made on the basis of pressed wood flour or pressed wood chips).
  • HMPP wood flour polypropylene
  • cotton fiber or plastic injection molding a material made on the basis of pressed wood flour or pressed wood chips.
  • a polyester is usually used as the laminated material.
  • the retainers, which hold the clips for attachment to the frame and the crash pads, are subsequently glued to the carrier part.
  • a disadvantage of such a method or a product produced by such a method are the many handling processes and the associated costs, as well as the large number of different materials which complicate or prevent later recycling.
  • the object of the invention is therefore to provide a method for producing such parts / systems which is considerably simpler and therefore less expensive and leads to a component with improved properties. It can also be seen as an improvement if the weight of such parts can be significantly reduced and the "system" can be manufactured using only one material for optimized recycling. This object is achieved by the measures specified in the characterizing part of patent claim 1. Carrier part with decor, the energy-absorbing cushion and fastening elements are produced in one work step. The invention further relates to various advantageous developments.
  • the material that serves as decor is directly back-foamed by polypropylene (EPP), so that an integral part is created in one operation.
  • EPP polypropylene
  • Foaming of the EPP can be integrated in the shape of the support part.
  • PP is also preferably used as the material for these retainers.
  • Figure 1 shows a door inner cushion part for a motor vehicle
  • Figure 2 is a cross section along the line II-II in Figure 1;
  • Figure 3 shows the area III in Figure 2 in an enlarged view
  • Figure 4 is a schematic representation of the
  • the door interior upholstery part 1 for a motor vehicle seen from the inside in FIG for the door lock button, etc. are provided.
  • this information is only exemplary.
  • the invention can also be parts for the interior of the cockpit, roof, etc.; parts of course also come outside the car production in question (such as upholstery parts in the furniture industry or in the leisure sector).
  • FIGS. 2 and 3 The structure is shown in detail in FIGS. 2 and 3.
  • the fabric 5 is back-foamed with particle foam 6.
  • Door interior upholstery part 1 takes place, as can be seen from FIG. 4, in a mold 11, 12.
  • the material 5 On the surface of the mold on which the upholstery part 1 is to be covered with the material 5, the material 5 is inserted into the mold, that is to say in part 5 of the Form, held with a variety of small vacuum suction channels 13. For this it is necessary that the material 5 is also sufficiently tight, either itself or through the foam backing 7.
  • foam particles are pressed into the mold through filling channels 14 with an overpressure of 2 to 3 bar and there with superheated steam, which is caused by further (not shown) ) Nozzles is pushed, applied so that they expand and at the same time on their surface melt and glue.
  • This foaming of EPP particles under superheated steam is known per se. What is new in the present case is that the direct and final connection of the particle foam 6 with the material 5 takes place already in the form and through the foaming process itself.
  • the material 5 is also advantageously made of PP. It is preferably a knitted fabric (no fabric) that is stretchable at least in one direction so that it can permanently adapt to the shape of the upholstered part without wrinkling, without overstretching and without impairing the appearance and the feel.
  • the foam back 7 is also made of EPP or EPE (polyolefin) foam; here, however, it is harmless to the basic idea of the invention if small constituents of other polyolefins (EPE) are used, since the proportion of this constituent in the total product is extremely small, so that the one-component property of the entire product is not significantly impaired thereby.
  • EPE polyolefin
  • Corresponding retainers 8 are foamed into that side of the upholstery part, the left side in FIGS. 1 and 2, which faces away from the side visible in use Clips 9 are used. This is used to fasten the cushion part to the frame of the door of a motor vehicle.
  • a small bending area 10 protrudes from the fabric 5 at the edges of the surface visible in the installed state. After foaming, this still has to be bent and glued. If possible, the folding area 10 is created and welded on one or more sides of the parts in the manufacturing process in order to reduce the necessary rework.

Abstract

L'invention concerne un procédé de production d'une pièce moulée (1) en plastique recouverte, au moins d'un côté, d'une matière, de préférence, d'un coussin destiné au revêtement de l'habitacle d'un véhicule automobile, comprenant des particules de matière moussée. Ce procédé consiste à mousser dans un moule (11, 12) la matière (5) et du polypropylène (EPP) expansible.
