Method and device for producing multicolored

molded skins

description

The invention relates to a method and an apparatus for producing multi-colored molded skins, in particular slush skins for a molded or component, in particular a vehicle component such. B. a decorative element.

For the production of multicolored molded skins, there are currently various production methods, such as. B. Spray technology with mask or shell or Hohlkörpergießverfahren (also called slush molding process) with two powder troughs. In the so-called shell casting method, after the application of a first covering skin layer, it is cooled down. Thereafter, a part is removed at a defined tear-off edge, in particular by means of a laser, and then both areas are covered over the entire surface with another skin layer. For this purpose, powder troughs are known, which have a shape adapted to the color area to be applied. These methods are very complicated and expensive.

The object of the present invention is to specify a simplified method and an improved apparatus for producing multicolored molded skins.

With regard to the method, the object is achieved by the features specified in claim 1. With regard to the device, the object is achieved by the features specified in claim 1 1.

Advantageous developments of the invention are the subject of

Dependent claims. In a method for producing molded skins, in particular slush skins for a molded or component, a tray comprising at least two different plastic materials and a galvano tray forming a molding are positioned relative to one another, wherein a separating element separating the plastic materials in the tray and projecting beyond the tray introduced into the Galvanoschale, positioned and optionally fixed and then from at least two sides the different

Plastic materials are applied separately from one another in a layer on the molding and the separator is removed from the Galvanoschale.

Such a method allows the production of two- or multi-colored molding, in particular slush hides in a one-step production step with only one tub, in particular powder tray with integrated seal and separating element (also called sword). In this case, the various plastic materials, in particular plastic powder, in the tub and when applied in the galvano shell by means of the integrated separating elements (swords) are separated. In addition, in the tub a

Partition be arranged to separate the materials. The method is particularly suitable for the production of two- or multi-colored

Form skins for invisible color separations (for example, covered there) or color separations, which are visible only in a small sub-area. Compared with conventional Schalengießverfahren the inventive method is simple and inexpensive.

The apparatus for producing molded skins comprises a Galvanoschale and a single tub, in particular material or Pulverwanne, which are freely positionable to each other, wherein the trough at least one

Separating element for separating introduced into the tub different materials, and wherein the separating element protrudes beyond the tub and an over the tub projecting end of the separating element in the Galvanoschale can be introduced and freely positioned.

The produced multicolored shaped skins, in particular thin slush skins with a skin thickness in the mm range, are used in particular for a molded part or component, in particular a vehicle component, such as eg. As a decorative element, such as an instrument panel or door sill used.

Essential features of the method and the

Device are the use of only one tub, in particular

Material tray (like powder tray or powder box) with appropriate sealing technology with integrated separating element (sword). In this case, the separating element with a sealing material, which from the

Masking technology is known, for. Silicone, coated. Likewise, the tub is sealed on the outside and inside.

In the process of producing two or more colors

Form skins are the tub, in which at least two or more different materials are arranged separately from each other, and a forming a form or component Galvanoschale positioned relative to each other, wherein a separating the materials and projecting beyond the tub separating element is introduced and positioned in the Galvanoschale and then the materials are introduced by means of the separating element separated from each other in at least one layer in the Galvanoschale.

The method enables the production of shaped skins of two or more colors in one or more layers in one and the same manufacturing process, in particular in a so-called slush process.

In one possible embodiment, the separating element can be adjusted in at least one freedom, in particular in height. Alternatively or In addition, the tub can be adjusted in at least one freedom, in particular in height. As a result, the separating element, which

is arranged or fixed in particular movable in the tub, after the introduction of the materials in the Galvanoschale at least partially or completely removed from the layer of materials, so that the resulting separation point is closed by flowing into each other of the materials. Alternatively or additionally, another material, in particular in a further color, can be applied, in particular back-injected, at this separation point.

In a further embodiment, the separating element is in the positioned and / or fixed state of the tub and Galvanoschale against the

Inner wall of the Galvanoschale with a predetermined force,

in particular by means of spring force, pressed. This ensures a defined separation of the materials during introduction into the galvano shell, so that two- or multi-colored skins for non-visible color separations

(For example, by covering) or for color separations that are visible only in a small sub-range, are possible.

Appropriately, the separating element after introduction of the

Materials removed from the galvano shell. In this way, in the region of the separation point of at least two different, in particular differently colored materials, another different, in particular

differently colored material to be applied. Alternatively or additionally, the separation point can be further treated. For example, the

Separation point are sealed. In addition, by renewed

Positioning of the separating element after curing of a first introduced layer of materials at least one further layer of materials are introduced into the Galvanoschale. A development of the invention provides that the Galvanoschale is rotated during the introduction of the materials, resulting in the

Inner wall of Galvanoschale a layer of the different materials in the form of a compact molded skin separated from the

deposited materials and thus forms a multi-colored molded skin in different colored materials. In this case, the materials can preferably be deposited on the inner wall of the galvano shell in such a way that a multicolored layer corresponding to the number of materials forms.

A further embodiment of the invention provides that after

Deposition of the materials on the inner wall of the galvano shell in the form of a multi-colored layer, the separating element is at least partially or completely removed from the layer such that a defined

Separation point of the materials is formed. In particular, the separating element is removed such that the defined separation point has a maximum width of 0.5 mm, in which the materials are mixed together,

especially merge or gel together.

Depending on the application, another material can be applied in the region of the separation point of the materials. In particular, a different colored material for marking the separation point or a separation point

sealing material are applied. In addition, after

Remove the material tray, for example by means of a spray unit, z. As a robot, powder or a liquid plastisol, in particular a powdery or paste-like thermoplastic polymer, are sprayed onto the separation point during or before the sintering phase. During the sintering phase, the materials then fuse together.

A further development provides that the Galvanoschale is heated. This allows optimal curing and removal of the molded skin. About that In addition, in a simple manner, a multi-layered deposition of the materials and thus the production of multi-layered molded skins of different, in particular different colored, materials are possible.

A further embodiment of the invention provides that the

Separating element is cooled. As a result, the separating element with respect to the process heat is sufficiently dimensionally stable and solid, so that the

Materials are safely separated. In addition, the separating element can be used several times. Due to the contact of the separating element with the warm galvano shell, the separating element, in particular the contacting seal, heats up with each coating cycle. In this case, during the waiting time for the next cycle, the separating element,

in particular, do not sufficiently cool the seal. As a result, when retracting the separating element, there may be adhesion of gelled material in the form of threads or agglomerates or precipitation of gelled material on the back of the molded surface and thus thickening of the molded skin.

With regard to the device for producing two- or multi-colored molded skins for a mold or component, the object is achieved according to the invention by a tub in which at least two different

Materials are arranged separately from one another, and a forming or component forming Galvanoschale are provided, wherein in the tub separating the materials separating element is arranged and the tub and Galvanoschale are positioned relative to each other and the separator over the tub protruding into the Galvanoschale such can be introduced, that then the materials by means of the separating element separated from each other in at least one layer in the galvano shell can be introduced. Preferably, the Galvanoschale itself forms the form or component, for. As a glove box, an instrument panel or similar molding. In other words: The Galvanoschale has a form or Component corresponding shape and contour. Alternatively, a

conventional galvano dish can be used.

In this case, the separating element is provided, the different materials during mounting and / or introducing separate from each other, so that at

different colored materials a two- or multi-colored molded skin is formed. In this case, the materials can be introduced separately by the separating element by means of injection, pouring (slush method) or by powder introduction into the Galvanoschale, in particular applied to the inner wall.

The separating element can be extended or retracted, in particular, perpendicular to the axis of rotation, into the galvano shell.

In one possible embodiment, the separating element is designed as a sword. In particular, the end of the separating element protruding into the galvano-shell is provided with a defined shape, so that the materials are reliably separated. For example, the end protruding into the galvano shell has a conical shape. Alternatively, the end may have a pointed, round or rectangular shape. The shape of the end may correspond to a shape of a separating groove arranged in the galvano shell. Alternatively, the partition may be formed as a partition.

Also, a plurality of separating elements and / or partitions may be provided, whereby in particular a multi-colored molded skin can be formed. For example, a plurality of separating elements in the tub, in particular one of the number of colors of the multicolored molded skin corresponding number of separating elements arranged. The separating elements are arranged separately adjustable in the tub. Alternatively, the separating elements can also be adjusted together. Furthermore, the separating element can at least partially with a

Sealing material coated or provided or have a varying thickness. In particular, the protruding into the galvano shell end of the separating element itself from a sealing material, for. As silicone, be formed. This allows a secure pressing of the separating element to the inner wall of the Galvanoschale, so that the materials are safely separated from each other during the introduction into the Galvanoschale.

A further embodiment provides that the Galvanoschale is provided with an introduced into the inner wall separating groove, in which

in particular, the separating element can be positioned during the introduction of the materials. For this purpose, the separating element and the separating groove have mutually corresponding shapes and dimensions. Such an arrangement of the separating element in a separating groove enables a secure separation of the materials during introduction from one another and, after removal of the separating element, a defined fusion of the materials during curing with a defined separation point.

The advantages achieved by the invention are in particular in short process times and low thermal stress on the material. In addition, the process for the production of multicolor, in particular more than two colors, for. B. three-color molded skins made of PVC or other plastic suitable. In this case, in particular the one-piece multicolored mold skin has the advantage that downstream process steps such. B. foaming with a carrier part, punching, milling, etc. without

Extra effort compared to conventional multicolor and consequently separate components can be performed.

Provided with reference numerals.

1 shows schematically an apparatus 1 for producing a multi-colored molded skin 2, as shown in Figure 2. The device 1 comprises a galvano shell 3 and a trough 4 with integrated separating element 5.

The production of the molded skin 2 takes place in the Galvanoschale 3 (also

Galvanoform called). The shape of the Galvanoschale 3 determines the shape of the outer contour of the molded skin 2 (also called slush skin). In this case, at least two materials M1, M2 are in the Galvanoschale 3

introduced and separated from each other via the integrated into the tub 4 separating element 5.

According to the invention, the trough 4 for receiving at least two materials M1, M2, in particular powder, for. As polymer powder or PVC powder, the separator 5, which divides the tub 4 into chambers.

To produce a bicoloured molded skin 2, the galvano shell 3 rotates in a conventional manner, with a heatable

Inner wall of the galvano shell 3 of the materials M1, M2 forms a two-color layer in the form of the compact molded skin 2. FIG. 2 shows schematically an end 5.1 of the separating element 5 according to FIG. 1 projecting into the galvano shell 3 and a molded skin 2 formed in or on the galvano shell 3 from two materials M1, M2

Separating element 5 may be provided with a cooling device 6.

As shown in FIG. 2, the end 5.1 (also called sword tip) projects into the galvano shell 3 in such a way that it and the end 5.1 are in contact or at a small distance from each other.

In this case, the separating element 5 can be arranged fixedly or in at least one freedom movable in the tub 4. In particular, that can

Separator 5 height or longitudinally adjustable, for example, along the arrows P1, P2 be adjustable. Along the arrow P2 is the

Separator 5 made extendable or retractable, so that the two

Materials M1, M2 are always arranged separately in the tub 4 from each other and a two-color molded skin 2 is formed.

For a galvano dish 3 forming, for example, a glove box, a contour-adapted dividing wall (with tolerances of -1 mm) is produced transversely to the axis of rotation as separating element 5. This separator 5 is exactly positioned, z. B. over pins and sockets. This shows that

Separating element 5 along the longitudinal axis to a different thickness. For example, the separating element 5 is thicker in the region of the trough 4 than in the region of the end 5.1 projecting into the galvano shell 3. In particular, the end is 5.1 tapered.

For precise contour adaptation in the "warm" state, the galvano shell 3 is installed in a prototype installation The thin side of the separating element 5 is coated with a sealing material which is known from mask technology, eg silicone heated and moved into the position of a docking station, not shown, by hand, the separating element 5, in particular its end 5.1 introduced into the Galvanoschale 3, positioned and fixed, so that the materials M1, M2 introduced separately by the separating element 5 in the Galvanoschale 3 and can be cured.

After the curing process, the separating element 5 is removed from the galvano shell 3. Following the conical contour, the separating element 5 becomes so

nachgearbeitet that at the contact line of the separating element 5 and the Galvanoschale 3 a sealing or covering line with a width,

for example, from about 0.5 mm, arises.

For positioning the Galvanoschale 3 and the tub 4 with integrated separator 5 positioning and / or fixing elements, for. Pens,

Bushings, provided. By positioning help such as pin-socket connections (in the form of loose and fixed bearing), the reproducibility of

Positioning ensured.

If the Galvanoschale 3 is heated again and is located in the powder station, not shown, the separating element 5 is positioned, wherein on the separate from the separating element 5 sides of the inner wall of the Galvanoschale 3, the differently colored materials M1, M2 in a uniform thin, for example 1 mm thick layer are applied.

After this process, the separating element 5 is removed with the aim that during the sintering process, the two differently colored

Materials M1, M2 in a narrow region at their separation point T merge and give a maximum of 0.5 mm wide "mixed strip", as shown in Figure 4. Such a formed skin 2 with a thin "mixed strip" of both materials M1, M2 at their Separation point T is used in particular for molds or components with a non-visible - because completely covered color separation - applied.

In other words, the galvano shell 3 has an exact contour adapted to the molded part to be formed.

For the production of the molded skin 2, the Galvanoschale 3 is heated to about 200 ° C and determined their contour and / or surface structure by scanning.

Based on the determined contour and / or surface structure and possibly the positions of tub 4 and Galvanoschale 3, the tub 4 and the Galvanoschale 3 are positioned to each other, centered and then fixed, z. B. locked. In this case, the separating element 5 is based on the acquired data of contour and / or surface structure along the arrows P1 and / or P2, for example, pneumatically or mechanically adjustable in its end position and there in particular resiliently mounted.

The tub 4 is also sealed outside and inside.

In the basic position of the tub 4, the separating element 5 is retracted or retracted, for example by means of a Kurzhubzylinders.

After the positioning of the tub 4 and the separating element 5 and locked in the Galvanoschale 3 state of the tub 4 is the

Separating element 5 pressed against the inner wall of the Galvanoschale 3, for example by means of spring force. As a result, no compressed air supply to the tub 4 is necessary.

Subsequently, the device 1 is rotated and the materials M1, M2 are separated by means of the separating element 5 in and thus on the different sides the inner wall of the warm Galvanoschale 3 on and applied and poured the seal or molded skin 2 as a solid material and sintered analog mask technology. The Galvanoschale 3 can be warmed up to 230 ° C.

After rotation and introduction of the materials M1, M2 and

Curing the separator 5 is removed, for. B. brought out, and the two applied materials M1, M2 merge together during the sintering or curing phase.

For this purpose, the tub 4 is unlocked from the Galvanoschale 3 and decoupled. To avoid the ungelled material M1, M2 falls into the tub 4, suitable means are provided.

For a uniform wall thickness and a convergence of the

Materials M1, M2 at the separation point, the molded skin 2 can optionally be back-sprayed in this area of the separation point with further material, in particular PVC powder or a liquid plastisol.

The Galvanoschale 3 is placed in a defined sintering position.

The molded skin 2 is then cooled to a removal temperature, removed and thus removed from the mold. Subsequently, the molded skin 2 is checked for gloss, thickness, separation and other defects and cleaned the tub 4 with integrated separator 5.

Figures 5 to 10 show schematically an alternative embodiment of a device 1 'with a Galvanoschale 3' and with a two

Separating elements 5 ', 5 "having trough 4'. The two separating elements 5 ', 5" are used to separate the two materials M1, M2 when introduced into the Galvano shell 3. In addition, the tub 4 'a partition 7 to

Separation of the materials M1, M2 in the tub 4 'on.

The separating elements 5 ', 5 "are adjustable along the arrows P1 and / or P2, in particular displaceable, movable, retractable or extendable.

FIG. 5 shows the adjustment along the arrow P1. In the figure 6, the adjustment along the arrow P2 is shown. In Figure 7 is shown how the separating element 5 'by means of a slider S1 in a closing or

Separation position is driven, wherein the separating element 5 "is in an open position, so that a corresponding separation of the materials M1, M2 takes place during introduction into the Galvanoschale 3, as shown in Figure 8.

Figure 8 shows the device 1 'with closed slide S1 and open slide S2 and after the first rotation of the device 1', whereby a two-part molded skin 2 'in the mm range, z. B. of 0.6 mm is formed. Figure 9 shows a slide change, i. Slider S1 is opened and slider S2 is closed, as shown in FIG. After a second rotation of the device 1 ', a further layer is applied to the molded skin 2' with a thickness of, for example, 1, 2 mm. To improve the transition or separation point of the two materials M1, M2 of the molded skin 2 ', several slide changes and rotations with subsequent sintering and cooling phase can be performed.

Figures 1 1 to 14 show schematically in detail different

Exemplary embodiments of a separating element 5 (5 'or 5 ") with the conically executed end 5.1 In the illustrated exemplary embodiment according to FIG. 11, the end 5.1 is integrated into the separating element 5, in particular

trapped. Alternatively, these may be integrally formed as a component. The end 5.1 serves as a seal to the inner wall of the Galvanoschale 3 and thus separation of the applied materials on the inner wall M1, M2 and is preferably formed from a sealing material, in particular silicone.

According to Figures 12 to 14, the end 5.1, also called tip or seal, different cross-sectional shapes, for. As a pointed shape, a round shape or a rectangular shape, have.

FIGS. 15 to 19 schematically show different embodiments of a dividing groove 8 integrated in the galvano shell 3 and the end 5.1 of the dividing element 5 of the trough 4 for forming a defined separation point of different materials M1, M2 of the molded skin 2.

The dividing groove 8 can analogously to the end 5.1 have different cross-sectional shapes, z. As an acute-angled shape, a round shape, a polygonal shape or a wide-angle shape. The dividing groove 8 preferably has a wider cross-sectional shape than the end 5.1 of the dividing element 5. For example, the separating groove 8 has a flat V-shape and the end 5.1 has a steep V-shape (see FIGS. 16 and 19).

Ideally, the separation groove 8 (also called color separation groove) is introduced into the galvano shell 3 at a 90 ° angle to the axis of rotation, as a result of which a lower tendency to mix the color when these rotate side by side can be achieved.

FIG. 20 schematically shows an exemplary embodiment of a layer of a covered color separation for a molded skin 2.

FIGS. 21 to 22 schematically show an exemplary embodiment for the sequence of producing a two-color molded skin 2 with a different-colored separation point T. In this case, two different materials M1 and M2 are applied by means of a separating element 5, analogously to the method described above separated from each other on an inner wall of a Galvanoschale 3 applied. The separating element 5 is arranged in such a manner in a trough 4 perpendicular to the trough bottom, that two chambers 9.1, 9.2 are formed, in each of which one of the materials M1, M2 are contained separately.

In addition, the separating element 5 protrudes beyond the tub 4 such that when a juxtaposition of tub 4 and Galvanoschale 3 during the casting process pointing towards Galvanoschale 3 end 5.1 of the separating element 5 against a molding 3.1 in the

Galvanoschale 3 is pressed. As a result, the separated in the tub 4 by means of the separating element 5 materials M1, M2 are also separated when applied to the inner wall, so that a molded skin 2 of two different, especially different colored materials M1, M2 is formed.

As shown, the formation 3.1 in the galvano shell 3 can be designed as an integrated elevation, in particular a sealing or separating seam, in order to support the separation of the materials M1, M2 when applied to the galvano shell 3. In one possible embodiment, the shape of the end 5.1 of the separating element 5 corresponds to the contour or shape of the molding 3.1. Alternatively, the shape 3.1 as a groove, such as the dividing groove 8 shown above, be formed.

The separating element 5 is arranged perpendicular to the axis of rotation of the device 1 in the closed arrangement of the tub 4 and Galvanoschale 3. During the application of the materials M1, M2 on the inner wall of the Galvanoschale 3, the device 1 is rotated about the axis of rotation.

The Galvanoschale 3 can be preheated and / or heated continuously, inter alia to optimize the curing process. Subsequently, the tub 4 with the separating element 5 or

Separator 5 separately removed from the inner wall of the Galvanoschale 3. The separator 5 may be an integral part of the tub 4, in this embodiment, the tub 4 together with the

Separating element 5 relative to the Galvanoschale 3 movable, in particular height and / or is longitudinally adjustable. Alternatively or additionally, the

Separating element 5 separately formed and movable, in particular height and / or longitudinally adjustable in the tub 4 may be arranged.

To connect the two materials M1, M2 in the region of the separation point T, a further material M3 is subsequently sprayed on. For this purpose, the tub 4 is completely removed from the Galvanoschale 3 together with the separating element 5. In the region of the separation point T, the at least partially cured molded skin 2 with a further material M3, z. As a PVC powder or a liquid plastisol, sprayed or back-injected. For this purpose, a spray unit 9 can be arranged correspondingly with respect to the separation point T.

The further material M3 may have a different color than the materials M1, M2, for example to mark the parting line or separation point T.

Subsequently, the Galvanoschale 3 is brought into a defined sintering position and the molded skin 2 is cooled to a withdrawal temperature and thus removed from the mold.

FIG. 23 shows the cooled and demolded molded skin 2 formed from the two materials M1, M2, which are fused together at the separation point T and are back-injected thereon with a further material M3. Figures 24 to 27 show schematically an embodiment of the process of producing a two-color molded skin 2 with fused at the separation point T materials M1, M2 without back injection.

The materials M1, M2 are held analogously as described above by means of the separating element 5 separately in the tub 4 and separated from each other in the Galvanoschale 3 introduced.

After application and partial curing or gelling of the materials M1, M2, the tub 4 and Galvanoschale 3 are arranged to each other, in particular rotated, that the Galvanoschale 3 is positioned below, as shown in Figure 25. Subsequently, at least the separating element 5 is removed from the inner wall of the galvano shell 3, in particular by a few

Millimeter raised. The two materials M1, M2 fuse together in this region of the separation point T and gel and harden. Alternatively, the tub 4 can be raised with the separating element 5.

Figures 26 and 27 show the resulting molded skin 2 with fused in the region of the separation point T materials M1, M2.
