Definitions
- the invention relates to a method and a device for producing multi-component molded plastic parts.
- Multi-component molded plastic parts are, for example, oil pans with a circumferential seal for automobiles, housing covers with circumferential seals, structural components with damping elements, melamine-colored components, etc. or structural components with a core or a layer made of fiber material such as glass fibers or synthetic fibers and a molded or overmolded plastic body.
- thermoplastic part with an injected elastomer seal
- a two-stroke injection molding process In a first cycle, a thermoplastic base body is produced in a mold with retractable cores. In a second cycle, the cores are withdrawn and elastomer material is injected into the resulting cavity.
- indexable insert machines are known in which an indexable insert is rotatably arranged on a turntable between a movable and a fixed platen.
- the indexable insert carries a tool half on each side, which interact with a tool half on the fixed platen or on the movable platen.
- an injection unit is assigned to each of the fixed platen or movable platen.
- In-mold compounders are known per se (DE-PS-114 22 29). They include an extruder, in which plastic material is plasticized, and an injection cylinder, in which the plasticized plastic material is fed, possibly with the interposition of a pressure accumulator, and then injected from the injection cylinder into a mold.
- a multi-phase plastic mass is produced in the extruder, for example by adding glass fiber material, carbon fiber material, mixing systems or fillers for the production of highly filled molding materials.
- This material is used as a component in the injection molding process for the production of multi-component plastic parts.
- Other materials can also be prepared and injected using an in-mold compounder or another known injection molding unit.
- Elastomers in the form of crosslinking plastics, rubber or LSR or thermoplastic elastomers are suitable as a further component.
- a preliminary product made of fiber material is formed into a preform in the first work area, and at the same time a preform is subjected to an injection molding process in the second work area, ie plastic material is injection molded onto the preform or the preform is overmolded with plastic material.
- the finished plastic molded part is then removed from the second work area, and the preform produced in the first work area is transported to the second work area via the indexable insert.
- woven or nonwoven materials made of glass, natural, carbon or synthetic fibers, preferably in the form of an endless belt; the plastic material is preferably a thermoplastic.
- indexable insert machines are particularly suitable for use with two injection units.
- Such a structure can also be used according to the invention in order to inject an additive into the second working area when the preform is formed.
- This additive can be, for example, a hardener to harden synthetic fibers, a binder to prevent the preform from expanding when the mold is opened, a plastic material or an additive that improves the adhesion of the fiber material to the plastic to be injected later.
- the figure shows an injection molding machine with a fixed platen 2, a movable platen 4 and a turning plate 6.
- the mold platen carry Molding tools 3, 5, which together with the insert 6 form cavities for the production of plastic molded parts.
- the indexable insert 6 and the movable platen 4 are axially displaceable, the movable platen 4 being moved toward or away from the fixed platen 2 via spars 8 which are guided through the fixed platen.
- a drive 10 and (schematically) a first injection unit I and a second injection unit II.
- the entire structure comprising the drive and the platen is mounted on a module frame 20, which in turn is attached to a machine bed 35 of the injection molding machine.
- a first work area A is formed between the movable platen 4 and the insert 6 and a second work area B is formed between the insert 6 and the fixed platen 2.
- a fiber material is introduced into the mold cavity of the first working area A, preferably in the form of an endless belt, as indicated by the arrow P.
- the molds are then closed by moving the movable platen 4 and the turning plate 6 towards the fixed platen, and a preform is formed in the first work area, while at the same time a preform with plastic that has already been produced is made in the cavity of the second work area B by means of the second injection unit II is encapsulated.
- the injection unit I shown in the figure is optional and, if necessary, can be used to inject an additive into the cavity of the first working area A when the preform is formed.
- injection screw devices are shown as injection units; instead or in combination with it, in-mold compounders can also be used.
