Definitions
- the invention relates to a composite component with partially movable elements according to the preamble of claim 1 and a method for its production according to the preamble of the independent claim 6.
- a ventilation flap for passenger cars is known in order to allow automatic transport of air from the interior of the passenger car to the outside when a certain pressure inside has been exceeded, for example when fresh air from outside is in via the ventilation flaps the vehicle interior is let in.
- This ventilation flap has a base body and flaps that are movable relative to it, each made of a solid thermoplastic.
- a strip made of a thermoplastic elastomer is provided in the connection area between a flap and the base body, which has a thinned area along the axis of rotation, which acts as a joint.
- a further strip made of a thermoplastic elastomer is provided on the flap, which, when closed, rests on the base body.
- composite parts with partially movable elements e.g. a flow-through membrane, in which a membrane can be movably attached to a tube part in a manner similar to that previously, via a hinge made of an elastic plastic component.
- a disadvantage of the previously known composite parts is that two hard components and one soft component with an area acting as a joint are first produced separately and then have to be assembled with one another in a complex manner. Proceeding from this, the object of the invention is to specify a composite component with a partially movable element which is simpler in construction and manufacture in comparison with the prior art. Furthermore, the invention is based on the object of specifying a method for producing such a composite component.
- FIG. 2 cross section through the turning tool along the line A-A
- FIG. 3 perspective view of a finished composite component in the first embodiment of the invention
- an injection mold 8 has, as a fixed mold half, a turning tool 1 with two identical mold nests 6 and 7 for the production of tubular elements 2.
- a movable mold half, not shown here, which contains the negative of the tubular element 2 in the region of the mold cavity 6 and the negative of the membrane 3 to be molded in the region of the mold cavity 7 serves to inject the membrane 3.
- the injection mold 8 is opened and a plasma nozzle 4 is opened using a suitable one Handling system 10 retracted into the open injection mold.
- the plasma nozzle 4 is moved in the area 2a over the tube element 2, so that in this area the thermoplastic tube element 2 is exposed to a plasma jet.
- the plasma nozzle 4 is moved out of the injection mold, the injection mold is closed and the membrane 3 is molded from an elastic plastic onto the thermoplastic tubular element.
- the tube element 2 is acted upon by the plasma jet with the additional use of an aperture or mask 5, which only allows the plasma jet to pass through openings 5a, 5b and 5c.
- an aperture or mask 5 which only allows the plasma jet to pass through openings 5a, 5b and 5c.
- the tubular element 2 is only exposed to and treated with the plasma jet in the areas 2a, 2b and 2c.
- a connection between the thermoplastic tubular element 2 and the membrane 3 is established only in these areas mentioned.
- the membrane 3 can thus be lifted up from the tubular element 2 in the areas between the sections 2a, 2b and 2c, for example when a liquid flows through the tubular element (from bottom to top in FIG. 5).
- the membrane 3 is pressed onto the edge of the tubular element 2 and seals it against flow.
- the present invention has been described with reference to a thermoplastic tubular element with an attached membrane made of an elastic plastic. It goes without saying that other composite components can also be produced in the manner according to the invention. It is only necessary to ensure that plasma treatment takes place in those areas in which the elastic component is to be connected to the solid plastic and not in the other areas. This is because an adhesion-activating or increasing effect should only be produced in the connection areas, which is sufficient to produce a connection between the hard and the elastic components in these areas.
- Suitable plastics for the solid component are thermoplastic materials such as PP, PC, PBT, PA, ABS and the like.
- Thermoplastic elastomers such as TPE, TPU, TPO and other or crosslinking elastomers such as LSR, NBR, CR and others can be used as elastic plastics.
- the selection of plastics depends on the respective application area and is within the scope of professional skill. When making the selection, however, care must be taken to ensure that no liability is achieved between the solid and the elastic component in the "normal" manner of injection molding, that is to say without plasma treatment.
- a suitable plasma nozzle 4 has a stainless steel housing 11 with a nozzle head 12 and an insulation layer 13 on the inner wall of the housing 11.
- a pinhole 15 divides the interior of the housing 11 into a gas supply space 16 and a gas discharge space 17.
- a first electrode 18 is attached to the pinhole 15 and is connected via a line 19 to a high voltage source, not shown here.
- the nozzle head 12 of the stainless steel housing 11 acts as a second electrode which is grounded.
- a plasma 20 is ignited between the electrode 18 and the nozzle head 12, which emerges from the nozzle and strikes the surface of the molded part 22 as a plasma gas stream 21.
- a uniform and comparatively gentle treatment of the preforms 2 is possible.
