Definitions
- the invention relates to a method for producing a plastic-metal composite component, in which the molded parts of the composite component are connected by joining and by means of molded thermoplastic.
- Plastic-metal composite components in the form of hollow-chamber composite components are e.g. known from DE-A 198 48 516.
- Injected thermoplastic material is used to connect the half-shell to the cover plate or cover shell.
- the half-shell and the cover plate have e.g. a peripheral edge, which is provided with openings on which, for. .Rivet connections made of molded plastic are attached.
- beads can also be provided, on which a shear-resistant, form-fitting connection can also be produced by means of molded plastic.
- DE-A 198 48 516 discloses other methods for connecting two or more molded parts, such as welding, gluing, flanging, clinching, riveting, which can be used individually or in combination for connecting molded parts.
- DE-A 195 00 790 discloses a method and a device for producing plastic-metal composite components by a combination of metal joining technology and conventional injection molding methods in the cavity of a modified injection molding tool.
- a first step individual sheets or sheet profiles to be joined are placed in the injection mold and are connected to one another in a form-fitting manner by pressing or joining using a press ram.
- a second step are also through
- Pressing or stamping is a separate process step in which movable stamps are pressed onto the molded parts in the injection mold.
- the press stamps are embedded in the injection mold.
- the punches for pressing the molded parts are extended and retracted in the closed injection mold before the thermoplastic is injected into the mold cavity of the injection mold.
- the cycle time for the production of a composite component is accordingly relatively long.
- Another disadvantage is that the device required is relatively complex, since it has movable stamps for pressing the molded parts.
- the highly mechanically stressable plastic-metal composite components are used as lightweight components, for example in vehicle construction.
- the invention relates to a method for producing a plastic-metal composite component, consisting of one or more molded parts made of metal or plastic, the molded parts being joined in an injection mold and positively connected by means of thermoplastic, characterized in that the joining of the Molded parts are made when the injection mold is closed.
- the composite component according to the invention is composed of at least one molded part.
- the molded parts can have any geometric shape.
- the composite component can for example consist of a single molded part, e.g. a roll profile, which is added to a hollow chamber composite component.
- the composite component can e.g. can also be constructed from two molded parts, the molded parts being, for example, two half-shells or one half-shell and a cover plate, which together form a hollow-chamber composite component.
- the shear-resistant, positive connection of the film part or of the molded parts which are inserted into the injection mold is achieved by joining when the injection mold is closed.
- the joining is carried out by stamping when the injection molding tool is closed.
- the injection mold has embossing dies or cores, which press on the molded parts when closing and emboss the molded parts.
- the embossing cores protrude into the mold cavity of the injection molding tool, so that the embossing cores press onto the molded parts lying in the mold cavity.
- the molded parts preferably have an edge region in which the molded parts lie against one another or one above the other.
- the stamping is preferably carried out in the edge region of the molded parts lying against one another.
- a one-piece molded part preferably has two edge regions which are placed one above the other or to one another for connection.
- the Embossing can take place on one or both sides.
- the embossing cores alternately press on one and the other molded part along the edge region. If the edge region of the molded parts lies essentially horizontally in the injection molding tool, the edge region is mutually stamped by stamping cores from above and below.
- the molded parts have openings lying one above the other in their superimposed edge regions.
- the adjustment also takes place when the injection mold is closed, in that the edges of the openings are reshaped with the help of the embossing cores, similar to a flare.
- the openings lying one above the other are not of the same size. For example, essentially round openings can have different diameters. Then when you close the
- Injection mold only the molded part that has the smaller openings.
- the edges of the smaller openings are shaped using the embossing cores so that they protrude into the larger openings of the other molded part.
- the two molded parts are pressed together by pressing the covering molded part into the openings of the adjacent molded part in the area of the openings.
- the joining consists in the linking or interlocking of the two molded parts with one another when the injection mold is closed.
- the molded parts preferably have no continuous edge area. Instead, the edge region is designed in tab-like fashion only in individual sections.
- the width and the geometry of the tabs as well as the distance between two adjacent tabs can be chosen as desired. In the simplest form, the width of the tabs is essentially equal to the distance between two adjacent tabs. The tabs of the two molded parts are just positioned so that when the molded parts are placed against one another or one above the other, the tabs of one molded part fit into the gap between two adjacent tabs of the other molded part.
- the embossing cores press the tabs of the molded parts together, so that the tabs engage with one another and essentially lie in one plane. In this way, the pressed tabs form a continuous, closed edge area.
- the two molded parts has tabs of any geometrical shape, for example round or angular.
- the other molded part has a continuous edge area with openings for receiving the tabs of the first molded part. The geometry and size of the openings are chosen so that they form the counterpart to the tabs and take up the tabs straight.
- the molded parts are additionally connected to one another by injection-molded thermoplastic.
- Injection molding of the thermoplastic takes place in the same injection mold.
- the molded parts in particular in their edge area, preferably have openings and / or beads, in the area of which the plastic is injection-molded and passes through the openings or into the beads. Additionally or alternatively, the edges of the molded parts can also be extrusion-coated.
- Other methods for connecting molded parts by means of molded thermoplastic are e.g. described in DE-A 198 48 516.
- the advantage of the process according to the invention lies in the fact that no additional work step is required for the joining, in particular stamping, passing through and / or toothing, but rather the joining takes place in one step with the closing of the injection molding tool.
- This also has the advantage that the injection mold no movable components such as punch or the like..; which can be moved up and down in the closed injection mold or are extended and retracted, has more.
- the injection mold only has pins or the like, which press on the molded parts when the injection mold is closed.
- the molded parts consist of metal, in particular steel, nickel, chromium, iron, copper, zinc,
- PC Polycarbonate
- PU thermoplastic polyurethane
- polyester especially polyethylene terephthalate (PET), polystyrene (PS), syndiotactic polystyrene, acrylonitrile-butadiene-styrene (ABS), polypropylene oxide (PPO), polysulfone (PSO), polyphenylene sulfide (PPS), polyimide.
- PPO polypropylene oxide
- PSO polysulfone
- PPS polyphenylene sulfide
- PI polyether ether ketone
- PA polyamide
- PBT polybutylene terephthalate
- PP polypropylene
- PE polyethylene
- a particularly suitable non-reinforced, reinforced and / or filled plastic based on polyamide (PA), polyester, in particular polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polystyrene (PS), syndiotactic polystyrene, is suitable as the thermoplastic for the positive connection of the molded parts to one another , Acrylonitrile-butadiene-styrene (ABS), polybutylene terephthalate (PBT), thermoplastic polyurethane (PU), polyolefin, especially polypropylene (PP), polyethylene (PE), polycarbonate (PC), polypropylene oxide (PPO), polysulfone (PSO) , Polyphenylene sulfide (PPS), polyimide (PI), polyether ether ketone (PEEK) or a mixture of these plastics.
