Definitions

  • the invention relates to a molded plastic part which comprises a plastic carrier with a plurality of fields, at least one of these fields being laminated with a covering material and at least one other of these fields being sparkling clean, and to a method and a device for the production thereof.
  • a plastic molded part of the type mentioned is known from DE 44 08 446 AI.
  • a corresponding method and a corresponding device are also disclosed in this publication.
  • the plastic carrier is produced in one piece in a single operation.
  • the plastic carrier is uniformly introduced into the mold cavity with very low pressure and a very low flow rate.
  • the surface quality in the blank areas can not be optimal in unfavorable cases due to the low pressure.
  • air pockets or faulty formations can occur in these areas, which either have to be reworked or, since this is sometimes not possible, lead to rejects in the production of the plastic molded parts.
  • Another disadvantage of the known plastic molding is that due to the low pressure and the low flow velocities, in particular with large overall component dimensions, it is sometimes difficult to achieve an even distribution of the plastic carrier in the mold cavity. For the sparkling bright field is a relatively high quality and therefore expensive
  • Plastic material required which must also be used in the laminated areas due to the one-piece plastic molded part.
  • the object of the invention is therefore to create a molded plastic part of the type mentioned at the outset, which has a uniform, optimal quality in its injection-molded areas and in its areas laminated with a covering material.
  • the plastic carrier of the injection-molded field consists of a plastic injected under high pressure
  • the plastic carrier of the laminated field consists of a plastic introduced under relatively low pressure and at a low flow rate.
  • the high pressure with which the plastic carrier of the injection-molded field is injected achieves a very good surface quality on the visible side of the plastic carrier.
  • filigree surface patterns which are used, for example, in vehicles for matting the surfaces, can also be produced reliably and without the risk of air pockets.
  • recesses such as for loudspeakers in door panels of motor vehicles. testify, precisely producible, because of the high pressure and the possibly high flow rate of the injected plastic, even complicated geometrical shapes can be injected with high quality.

  • This bare connection field can be made extremely narrow.
  • the bare connecting field holds the edge of the cover material securely, and a visually pleasing exterior is created, especially with different cover materials.
  • plastic molding according to the invention is characterized in that the plastic carrier of the injection-molded field is made of a high quality plastic and that of the laminated field is made of a less high quality plastic.
  • This further development makes it possible to achieve noticeable cost savings, since an expensive plastic material is only used for the bare injection molding fields, in which the plastic carrier remains visible on the visible side of the finished plastic molded part, whereas the laminated fields, which often have a large part of the Identify the plastic molded part and its plastic carrier on the visible side of the finished plastic molded is partially covered by the cover material, an inexpensive plastic material is used.
  • a particularly durable and high-quality design of a molded plastic part is disclosed in claim 4: Thereafter, the protruding edge of the covering material of the laminated field is extrusion-coated by the plastic carrier of the adjacent, blank area.
  • This bare injection-molded field can also be an injection-molded connection field to which a further field, which may be covered with different covering material, adjoins. This further development reliably prevents the covering material in the edge region of the laminated field from detaching from the plastic carrier during the service life of the molded plastic part.
  • edges of the covering material are determined so that the mold cavity of the laminated field is tightly separated from the other fields;
  • the plastic carrier of the laminated field is first and then the plastic Fabric carrier of the splash-free field made.
  • the mass cake is introduced into the mold cavity of the laminated field in a relatively flat manner over the base area of the die.
  • the method according to claim 8 is particularly cost-effective if the molding of the mass cake in the mold cavity of the laminated field is carried out by closing the molding tool clamped on a normal press.
  • the method can also include the work steps in the following order:
  • the mass cake is introduced into the mold cavity of the laminated field via a low-pressure nozzle, since this enables the mass cake to be introduced particularly quickly.
  • This nozzle is preferably a wide slot nozzle.
  • the molding of the mass cake in the mold cavity of the laminated field is carried out according to claim 11 via a press ram, the flow rates being kept low and the pressure on the mass cake being controlled very well.
  • the invention is based on claim 12
  • At least one frame slide which can be moved through into the mold cavity and with which the edge of the covering material can be fixed along at least part of the boundary of the laminated field; d) at least one nozzle through which the melt of the plastic carrier can be introduced;
  • the molding tool is integrated in a press with two parts which are movable relative to one another;
  • the first die is movable parallel to the press stroke and is supported by a spring element against one part of the press, the maximum spring travel of the spring element being smaller than the maximum press stroke;
  • the second die is connected to the other part of the press.
  • the particular advantage of such a device according to the invention is that the molding tool is installed in a normal press, so that the costs for producing such a device are significantly reduced.
  • all the steps of the method according to the invention can be carried out in this one device, which further reduces the manufacturing costs of the molded plastic part.
  • the spring element is a spring cushion, because this enables the high support forces to be absorbed particularly well, the spring force of the spring cushion being sufficiently constant over the entire spring travel.
  • the nozzle which introduces the melt into the mold cavity of the laminated field, is integrated in the press ram.
  • the press ram can take up a large area, so that the stroke of the press ram, which is necessary for pressing the mass cake, can be kept low.

  • the first die is connected to one and the second die to the other part of the press;
  • a robot which applies the mass cake to the mold cavity of the laminated field almost without pressure and relatively flat over the base area.
  • An advantage of this device is that the molding tool itself can be of a very simple design and can therefore be manufactured inexpensively. In addition, installation in a conventional press is possible in a simple manner. Finally, the use of a robot to apply the mass cake enables it to be spread over a relatively large area, so that when the mass cake is pressed, it only has to travel short distances and low flow rates can thus be achieved.

Abstract

De manière générale, les pièces moulées en matière plastique, qui comprennent plusieurs zones, dont une au moins est contrecollée avec un matériau de recouvrement, sont produites en une seule étape. Afin d'éviter que le matériau de recouvrement ne se déforme dans la zone contrecollée, le support en matière plastique de la pièce connue est injecté dans toutes les zones, à pression réduite, ce, au détriment dans certaines conditions, de la qualité des zones injectées en blanc. Il est de ce fait prévu, selon l'invention, de produire le support en matière plastique de la zone injectée en blanc (22, 30; 120, 130) en une étape, à l'aide de matière plastique injectée sous haute pression, le support en matière plastique de la zone contrecollée (18, 20; 118, 120) étant produit en une autre étape, à l'aide de matière plastique injectée à pression relativement réduite. L'invention concerne également un outil de moulage (10; 110) correspondant, permettant de produire la pièce moulée en matière plastique objet de l'invention, dans une presse classique.
