Definitions
- the invention relates to the use of an injection mold for the production of injection molded parts of different sizes which are produced in the back injection and back injection molding process.
- Automotive interior parts are often manufactured by injection molding. These parts are installed without lamination or they are provided with a lamination after their manufacture and before installation, which has a protective and / or aesthetic function.
- the lamination can also consist of a decorative layer and a foam layer to be arranged between this and the injection molded part in order to improve the grip of the molded part.
- foam-backed laminations in particular enlarge the pure injection molded part considerably.
- both the unbacked and the differently backed injection molded parts are made in identical vehicle parts installed, so that the available installation space is the same. Therefore, the injection molded parts themselves - depending on whether they remain uncovered or laminated or have laminations of different thicknesses - have to be of different sizes. This requires the use of different injection molds with different cavities, which is very expensive.
- a removable, shell-shaped insert is inserted into the injection mold for the production of injection-molded parts that have to be laminated later, which corresponds in shape to the lamination and reduces the cavity of the injection mold by the volume of the lamination, is possible with the help to produce only one single injection mold of injection molded parts of different sizes, whereby there is no restriction to only two different sizes, but any number of different sizes can be selected using a respective insert.
- an injection molded part that is used directly as a non-laminated molded part an injection molded part that is used for a simply laminated molded part is used, and an injection molded part, which is used for a molded part with foam-backed lamination, can be produced using a single injection mold and two different inserts.
- FIG. 2 shows the two mold halves according to FIG. 1 in the closed state of the injection mold
- Fig. 4 is a molded part formed by lamination of an injection molded part
- FIG. 5 shows the two mold halves according to FIG. 1 in the closed state of the injection mold containing an insert for producing the injection molded part for the molded part according to FIG. 4.
- the known injection mold consists of a female mold 1 and a male mold 2.
- FIG. 1 shows the mold in the open state, in which a hardened injection molded part can be removed from it.
- an injection molding is carried out in a known manner by injecting a flowable material and curing it in the cavity 3 formed between the die 1 and the die 2. part manufactured.
- the injection molded part 4 produced without using an insert has the shape of the cavity 3 according to FIG. 3. It is used in a laminated manner as a molded part, for example in the interior of a motor vehicle.
- the molded part shown in FIG. 4 consists of an injection molded part 5 and a lamination 6.
- This molded part is to be used instead of the injection molded part 4 shown in FIG. 3.
- the injection molded part 5 must be smaller than the injection molded part 4, namely by the dimensions of the lamination 6.
- the cavity 3 between the female mold 1 and male mold 2 is reduced accordingly by an insert 7, which has the dimensions of the liner 6, before the mold is closed and the flowable material is injected is introduced into the mold.
- the insert is located where the lamination 6 is applied after the production of the injection molded part 5.
- the injection molded part 5, which is smaller than the injection molded part 4 by the size of the lamination 6, is removed from the mold, which has meanwhile been opened. Further injection molded parts 5 can now be produced; if, on the other hand, the production of injection molded parts 4 is desired again, the insert 7 is removed beforehand.
- the insert 7 can also can be exchanged for another insert if a different lamination is selected.
- the thickness of the insert 7 can change over its cross section if, for example, certain areas of the laminated molded part are to be particularly padded.
- the insert 7 consists of a pressure and temperature resistant material such as a metal, a hard plastic or a glass fiber reinforced plastic.
- the insert 7 is fastened in the die 1.
- the removable attachment can be done by screwing or gluing; the use can also be held by magnetic forces.
- threads in the die 1 are required, which are covered by blind caps when the insert is removed.
- magnets permanent or electromagnets
- the insert 7 itself consists of magnetic material or is coated with such.
- the insert 7 has a certain minimum thickness for reasons of stability, even at the points that do not correspond to the surface areas of the injection molded part that are not to be laminated. However, this must be dimensioned such that the difference to an injection molded part manufactured without insert is negligible, i.e. e.g. 0.5 mm.
- the present invention therefore proposes a method for producing laminated and non-laminated injection molded parts in a single mold. gene, whereby a removable shell-shaped insert is inserted into the injection mold for the production of injection molding parts to be laminated later, which corresponds in its shape to the lamination and the cavity of the injection mold around the
- a shell-shaped insert for a corresponding injection mold is again proposed, this insert being arranged or to be arranged in the die of the injection mold.
- a shell-shaped insert should preferably consist of pressure- and temperature-resistant material, preferred embodiments of the invention provide that it consists of metal, hard plastic or glass fiber reinforced plastic. It is also advantageous if the shell-shaped insert is fastened or fastened in the injection mold, for example by gluing or screwing. It is also possible for the shell-shaped insert to be held in the injection mold by magnetic forces.
