Description

[0001] The invention relates to an injection molding apparatus configured to produce an injection-molded part provided with a decorative element, wherein the decorative element comprises at least one design element. Furthermore, the invention relates to a method for producing such an injection-molded part.

[0002] Such an injection molding device typically comprises a mold cavity in which the decorative element can be arranged; a mold with at least two tool elements that are movable relative to one another, in particular a punch and a die, in order to open and close the mold; a filling device that is designed to fill an injection molding compound into the mold cavity when the mold is closed or partially closed; and at least one fixing device that is designed to fix the decorative element in the mold cavity.

[0003] Such an injection molding device for producing an injection-molded part provided with a textile on one side is known, for example, from DE 100 09 304 A1. In this injection molding device, the textile, after being removed in a cut form from a supply device, is back-injected with injection molding compound in a closed mold and subsequently further processed. EP 2 127 845 A1 also shows such an injection molding device. JP H01 234218 A shows an injection molding device with a fixing device.

[0004] For further technological background, please refer to DE 10 2007 041 678 A1 and DE 199 06 054 A1.

[0005] The object underlying the invention is seen in specifying an injection molding device and a manufacturing method in order to enable a simplified and optimized production of an injection molded part with decoration and design element present in the decoration.

[0006] This object is achieved by an injection molding apparatus and a method for producing an injection-molded part having the features of the respective independent patent claims. Advantageous embodiments with useful further developments are specified in the dependent patent claims.

[0007] What is proposed is an injection molding device which is designed to produce an injection molded part provided with a decorative element, wherein the decorative element has at least one design element, and wherein the injection molding device comprises: a mold cavity in which the decorative element can be arranged; a mold with at least two tool elements movable relative to one another, in particular a punch and a die, in order to open and close the mold; a filling device which is designed to fill an injection molding compound into the mold cavity when the mold is closed or partially closed; and at least one fixing device which is designed to fix the decorative element in the mold cavity. It is provided that the injection molding device further comprises a feed element which is configured to introduce the decorative element into the opened mold and to align the decorative element relative to the mold in a desired position, wherein the feed element is configured to align the decorative element depending on a position and / or orientation and / or shape of the at least one design element.

[0008] The design element, which can also be referred to as a design element, can be, for example, a decorative seam, an embossing, an emblem, or the like. Using the injection molding device presented here, it is possible to optimally arrange and align a decorative element in the injection molding device that not only has a uniform or similar surface, but also contains at least one design element. The position, shape, or orientation of the design element is used as a reference to correctly position the decorative element in the mold before injection molding, in particular before back-injection with injection molding material. The decorative element can be, for example, a textile made of natural and / or artificial fibers, a (plastic) film, a piece of leather, a piece of imitation leather, or the like.The finished injection-molded part, in particular a decorative element back-injected with injection-molding compound, can be part of a paneling of an interior of a motor vehicle, for example in the area of ​​a dashboard, a door panel, a handrest, a storage compartment lid and the like.

[0009] The term "design element" used here encompasses, as already indicated above, various configurations of particularly visible and perceptible elements, such as a decorative seam, an embossing, an emblem, or the like. A decorative seam or seam could also be referred to as a functional element due to its function of connecting parts of the decorative element, but is also encompassed by the term "design element" within the scope of this application.

[0010] The injection molding device may comprise a first fixing device configured to fix the decorative element outside a region comprising the design element.

[0011] The first fixing device can have at least one punch-side and at least one die-side first fixing element, which are movable independently of the tool elements.

[0012] By means of such a first fixing device, it is possible to hold or fix the decorative element aligned in the desired position in the mold in this position until the mold is closed and at least part of the injection molding compound has been injected.

[0013] The injection molding device may have a second fixing device which is designed to fix the decorative element in the region of the design element.

[0014] The second fixing device can have a counter-contour section facing the decorative element, which is designed to align the decorative element in a form-fitting manner with a contour section of the design element.

[0015] By means of such a second fixing device, it is possible to hold or fix the decorative element aligned in the target position in the mold until the mold is closed and at least a portion of the injection molding compound has been injected. The counter-contour section can also be used when aligning the decorative element in the target position with the mold open, even if the second fixing device has not yet been set to a fixing or holding position.

[0016] The second fixing device can be associated with a vacuum device, which is particularly configured to fix the aligned decorative element to the stamp and to suction it in place using negative pressure. The vacuum device can comprise an insert that has the counter-contour section. The insert with the counter-contour section makes it possible to align the decorative element in the desired position before the vacuum device is activated to fix the decorative element.

[0017] Alternatively, the second fixing device can have at least one punch-side and at least one die-side second fixing element, which are movable independently of the tool elements. The die-side second fixing element can have the counter-contour section.

[0018] A die-side and a punch-side fixing element allow the decorative element to be optimally held in the desired position in the area of ​​the design element until the mold is closed and at least a portion of the injection molding compound has been injected. The counter-contour section of the punch-side fixing element can also be used to align the decorative element in the desired position with the mold open, even if the second fixing device has not yet been set to a fixing or holding position.

[0019] In the injection molding device, the feed element can have a plurality of holding elements, in particular needle grippers, which are designed to transport the decorative element and introduce it into the mold cavity.

[0020] The feed element can have an elastic support element configured to support the design element of the decorative element, particularly during alignment. The elastic support element can support the design element, particularly from the side of the decorative element to be back-injected. The elastic support element improves the alignment of the decorative element depending on the design element; in particular, it simplifies the positive positioning between a counter-contour section of the fixing device and a corresponding contour section of the design element.

[0021] In the injection molding device, the fixing device can be configured to fix the decorative element when the mold elements are closed and the injection molding compound is poured in, so that the injection molding compound is applied to the decorative element from only one side. In other words, the decorative element can, for example, rest against the die, and injection molding compound is poured onto the side of the punch, which then applies pressure to the decorative element from one side.

[0022] The injection molding device may further comprise at least one cutting device which is designed to cut the decorative element received in the mold cavity and aligned in the desired position, in particular to cut its edge contour

[0023] The injection molding device may further comprise at least one folding device which is configured to form a fold along at least one of the edges of the decorative element received in the mold cavity and aligned in the desired position.

[0024] Thus, in addition to the actual injection molding, the injection molding device can also be used to cut and / or form at least one fold, so that an injection molded part with decorative element and design element can be produced efficiently and in an optimized manner in the same device.

[0025] A method for producing an injection-molded part having a decorative element with at least one design element using an injection molding device as described above comprises the following steps: Inserting a decorative element into the mold cavity with the mold open; aligning the decorative element relative to the mold in a desired position at least partially using the feed element, wherein the alignment of the decorative element in the desired position is carried out depending on a position and / or orientation and / or shape of the at least one design element; fixing the decorative element in the desired position; closing or partially closing the mold; injecting, in particular back-injecting, injection molding compound such that the injection molding compound acts on the decorative element only from one side.

[0026] In the method, a positive alignment with respect to a contour section of the design element of the decorative element can be achieved by means of an alternating, particularly oscillating, movement of the feed element. This alternating movement is a rather small-scale movement, in the range of a few millimeters or tenths of a millimeter. The contour section of the design element and a counter-contour section in the mold can be optimally aligned with each other, with the alternating movement supporting the creation of the positive alignment.

[0027] In particular, the alternating movement also results in a relative movement of the elastic support element. Such a relative movement of the elastic support element improves, and in particular ensures, the alignment of the decorative element in relation to the design element.

[0028] In the method, the decorative element introduced into the mold cavity and fixed in the desired position can be processed in the mold cavity before or after the injection of injection molding compound, in particular it can be cut to size and / or at least one fold can be formed.

[0029] In this process, the decorative element to be processed have an at least partially flexible or rigid structure; and / or have a foamed material layer; and / or have a textile layer or a plastic layer or a leather layer; and / or be formed from several assembled, in particular sewn-together, decorative pieces.

[0031] In the Fig. 1 to 81 shows a schematic and simplified version of an injection molding device 10. The injection molding device 10 has a mold cavity 12 in which a decorative element 14 to be processed can be arranged. The injection molding device 10 further comprises a mold 16 with at least two tool elements 16m, 16s that can be moved relative to one another, in particular a punch 16s and a die 16m, in order to open and close the mold 10. The injection molding device 10 further has a filling device 18 that is designed to fill an injection molding compound into the mold cavity 12 when the mold 16 is closed. The filling device 18 is shown in simplified form as a channel section through which injection molding compound can be fed into the mold cavity 12.

[0032] The decorative element 14 to be processed by the injection molding device 10 comprises at least one design element 20. The design element 20 can be a decorative seam, an embossing, an emblem integrated into the decorative element, or the like. In the following description, a decorative seam is considered as a non-limiting example of a design element 20.

[0033] In the example shown, the decorative element 14 is formed from several assembled, in particular sewn-together, decorative pieces 14a, 14b. Referring to the figures, the decorative element 14 has a front side 22 on the right side, which later faces the interior of a motor vehicle. The left side of the decorative element 14 forms a rear side 24, which is bonded to the injection molding compound after injection molding.

[0034] In the area of ​​the design element 20 or the decorative seam 20, a sealing element 26 can be arranged on the back of the decorative element 14, which prevents the injection molding compound from penetrating the decorative seam 20 when the injection molding compound is injected. If the design element 20 is not designed as a decorative seam, but rather, for example, as an embossing or emblem that is integrally and / or materially bonded to the decorative element 14, the sealing element 26 can be omitted if necessary.

[0035] The injection molding device 10, which is located in the Fig. 1 to 8 , comprises a first fixing device 28, which is configured to fix the decorative element 14 outside an area having the design element 20 or the decorative seam 20. In the example shown, the first fixing device 28 comprises clamping elements 28m, 28s that are movable relative to the tool elements 16m, 16s and are configured to clamp the decorative element 14.

[0036] Furthermore, the injection molding device 10 comprises a second fixing device 30, which is designed as a vacuum device 30a on the punch side and as a clamping element 30m on the die side. Several vacuum lines 30a of the vacuum device 30a are shown in a simplified and exemplary manner.

[0037] In the example of Fig. 1 to 8 the vacuum device 30s also comprises a type of insert 30e which is designed to come into contact with the design element 20 when the decorative element 14 is inserted into the mold cavity 12.

[0038] The injection molding device 10 further comprises a feed element 32 configured to introduce the decorative element 14 into the opened mold 16. The feed element 32 is further configured to align the decorative element 14 relative to the mold 16 in a desired position, which will be described in more detail below.

[0039] The feed element 32 can, for example, have a plurality of holding elements 34, in particular needle grippers, which are designed to transport the decorative element 14 and to insert it into the mold cavity 12. In the example of Fig. 1 to 8 the feed element 32 has an elastic support element 36 which is designed to support the design element or the decorative seam 20 of the decorative element 14, in particular when aligning the decorative element 14 relative to the molding tool 16, which will be described in more detail below.

[0040] The injection molding device 10 can also have a cutting device (not shown here) which is designed to cut the decorative element 14 received in the mold cavity 12 and aligned in the desired position, in particular to cut its edge contour.

[0041] Furthermore, the injection molding device 10 can have at least one folding device 38, which is designed to form a fold along at least one of the edges of the decorative element 14 received in the mold cavity 12 and aligned in the desired position, which will be described in more detail below. In the example shown, the Fig. 1 to 8 The folding device 38 is arranged on the die 16m and can be moved relative to it in the vertical direction, which is indicated by the double arrow above the folding device 38 in Fig. 1 is indicated.

[0042] Based on the previous description of the structural design of the injection molding device 10, its use for producing an injection molded part with a decorative element 14 and a design element 20 is described below. The following description with reference to the Fig. 1 to 8can also be described as a process for producing an injection-molded part. It should be noted that for reasons of clarity, not every Figures 1 to 8 all reference symbols are included. If a reference symbol is not shown in a figure, the corresponding reference symbol can be found in any case in the Fig. 1 .

[0043] According to Fig. 1 and Fig. 2 the decorative element 14 is transported to the opened mold 16 by means of the feed element 32 and introduced into the mold cavity 12 (step S501). Fig. 2 shows an approximate positioning or rough positioning of the decorative element 14 in relation to the molding tool 16, in particular the stamp 16s or the insert 30e of the vacuum device 30.

[0044] The design element 20 or the decorative seam 20 has a contour 20k facing the stamp 16s. This contour 20k comprises a type of depression in the example of the decorative seam 20. The insert 30e of the vacuum device 30 comprises a counter-contour section 30g facing the decorative element 14. The alignment of the decorative element in a Fig. 3 The target position SP shown is determined depending on the position and / or orientation and / or shape of the design element or the decorative seam 20 (step S502). In this case, a positive alignment with respect to the contour section 20k of the design element 20 of the decorative element 14 can be achieved by means of an alternating, in particular oscillating, movement of the feed element 32 (S503). The positive alignment is also supported by the elastic support element 36, which presses the decorative seam 20 or the contour 20k in the direction of the counter contour 30g.

[0045] In other words, the feed element 32 performs a slight lifting movement, in particular a substantially vertical back and forth movement, so that the decorative seam 20, with its contour 20k or the recess, rests or engages in a form-fitting manner on the mating contour section 30g of the insert 30e. As a result, the decorative element 14 is aligned in the example shown, in particular depending on the shape of the decorative seam 20, and fixed in its desired position. The executed lifting movement is not limited to a vertical back and forth movement; it is also conceivable that an elliptical or circular movement is performed. The slight lifting movement can therefore have a horizontal movement component in addition to a vertical movement component. The mating contour section 30g can also be referred to as a seam gusset or seam gusset in this example.

[0046] According to a step S504, the decorative element 14 is then fixed in the desired position SP, which is shown in the Fig. 4 is shown.

[0047] In the injection molding device 10 of the Fig. 4 The decorative element 14 is fixed in particular by activating the vacuum device 30, so that the decorative element 14 is pressed or sucked into its aligned desired position against the punch 16. In addition, the first fixing device 28 is closed by moving the punch-side clamping element 28s toward the die-side clamping element 28m, so that the decorative element 14 is held and fixed between the two clamping elements 28m, 28s. Furthermore, the punch-side clamping element 30s of the second fixing device 30 is moved in the direction of the insert 30e of the vacuum device 30, so that the decorative element 14 is held or fixed, in particular, also in the area of ​​the design element 20 or the decorative seam 20.

[0048] In the Fig. 5 It is shown that after fixing the decorative element 14 in the mold cavity 12, the feed element 32 can be released from the decorative element 14 and removed or extended from the mold cavity 12. In the following Figures 6 to 8 The feed element 32 is therefore no longer shown, even if it may still be present or visible in the vicinity of the molding tool 16 in a concrete implementation.

[0049] According to Fig. 6 In a step S505, the forming tool 16 is closed. The punch 16s is moved relative to the fixing elements 28s and 30s to the die 16m. Furthermore, before or during this step, the folding device 38 can also be moved toward the lower edge of the decorative element 14 (S506), so that a fold 14u is formed on the decorative element 14. Additionally, it is also conceivable for the decorative element 14 to be cut to size in the forming tool 16, although this is not shown in the figures.

[0050] In Fig. 7 A step S507 is shown in which injection molding compound 40 is injected into the mold cavity 12. This involves back-injection molding of the decorative element 14, so that its rear side 24 comes into contact with the injection molding compound 40 or is bonded to it in a material-locking manner. During the injection of injection molding compound 40, the clamping elements 28m and 30m can be released or moved away. Such a movement can be active (regulated or controlled) or passive (via the melt pressure).

[0051] Fig. 8 shows the removal of the finished injection-molded part 42 from the mold 16 or the injection molding device 10. The finished injection-molded part 42 has the decorative element 14 with design element 20 or decorative seam 20.

[0052] Fig. 9 shows an example of a further injection molding device 100, with which an injection molded part 42 ( Fig. 17 ) can be produced. In the Fig. 9 to 17 Corresponding components of the further injection molding device 10 are marked with the same reference numerals as in relation to the injection molding device 10 of the Fig. 1 to 8 . Accordingly, with regard to the Fig. 9 to 17 It should be noted that the basic procedure and functioning of the injection molding device 100 is the same as described above with reference to the Fig. 1 to 8 described.

[0053] In contrast to the injection molding device 10 already described, the injection molding device 100 does not have a vacuum device 30 ( Fig. 1 ). In this injection molding apparatus 100, the second fixing device 30 comprises a die-side clamping element 30m, which is movable relative to the die 16m. The clamping element 30m has the counter-contour section 30g at its end facing the decorative element 14.

[0054] Furthermore, the feed element 32 for the injection molding device 100 does not have an elastic support element 36 ( Fig. 1), which is not absolutely necessary due to the two clamping elements 30m, 30s.

[0055] All other components of the injection molding device 100 are the same as those of the injection molding device 10 of the Fig. 1 to 8 , so that reference is made to the above description in this regard.

[0056] Based on the previous description of the structural design of the further injection molding device 100, its use for producing an injection molded part with a decorative element 14 and a design element 20 is described below. The following description with reference to the Fig. 9 to 17 can also be described as a process for producing an injection-molded part. It should be noted that for reasons of clarity, not every Figures 9 to 17all reference symbols are included. If a reference symbol is not shown in a figure, the corresponding reference symbol can be found in any case in the Fig. 9 or the Fig. 1 .

[0057] According to Fig. 9 and Fig. 10 the decorative element 14 is transported to the opened mold 16 by means of the feed element 32 and introduced into the mold cavity 12 (step S501). Fig. 10 shows an approximate positioning or rough positioning GP of the decorative element 14 in relation to the molding tool 16, in particular the die 16m or the die-side clamping element 30m, which has been extended in the direction of the decorative element 14 ( Fig. 10 ).

[0058] The design element 20 or the decorative seam 20 has the contour 20k facing the die 16m. In the example of the decorative seam 20, this contour 20k comprises a type of recess. The clamping element 30m comprises the counter-contour section 30g facing the decorative element 14.

[0059] The alignment of the decorative element in a Fig. 11 The target position SP shown depends on the position and / or orientation and / or shape of the design element or the decorative seam 20 (step S502). In this case, a positive alignment with respect to the contour section 20k of the design element 20 of the decorative element 14 can be achieved by means of an alternating, in particular oscillating, movement of the feed element 32 (S503). The positive alignment is also supported by the stamp-side clamping element 30s, which supports the decorative seam 20 or the contour 20k from the rear side 24.

[0060] In other words, the feed element 32 performs a slight lifting movement, in particular a substantially vertical reciprocating movement, so that the decorative seam 20, with its contour 20k or the recess, rests or engages in a form-fitting manner with the counter-contour section 30g of the clamping element 30s. As a result, the decorative element 14 is aligned in the example shown, in particular depending on the shape of the decorative seam 20, and fixed in its desired position. The counter-contour section 30g can also be referred to in this example as a seam gusset or seam gusset.

[0061] According to a step S504, the decorative element 14 is then fixed in the desired position SP, which is shown in the Fig. 12 is shown.

[0062] In the injection molding device 100 of the Fig. 12The decorative element 14 is fixed in particular by closing the clamping elements 30s, 30m, so that the decorative element 14 is clamped and held between them. Additionally, the first fixing device 28 is closed by moving the die-side clamping element 28m toward the punch-side clamping element 28s, so that the decorative element 14 is held and fixed between the two clamping elements 28m, 28s. Thus, the decorative element 14 is also held or fixed, in particular, in the area of ​​the design element 20 or the decorative seam 20.

[0063] In the Fig. 13 It is shown that after fixing the decorative element 14 in the mold cavity 12, the feed element 32 can be released from the decorative element 14 and removed or extended from the mold cavity 12. In the following Figures 14 to 17The feed element 32 is therefore no longer shown, even if it may still be present or visible in the vicinity of the molding tool 16 in a concrete implementation.

[0064] According to Fig. 15 In a step S505, the forming tool 16 is closed. In doing so, the die 16m is moved relative to the fixing elements 28m and 30m to the punch 16s. Furthermore, before or during this step, the folding device 38 can also be moved toward the lower edge of the decorative element 14 (S506), so that a fold 14u is formed on the decorative element 14. Additionally, it is also conceivable for the decorative element 14 to be cut to size in the forming tool 16, although this is not illustrated in the figures.

[0065] In Fig. 16A step S507 is shown in which injection molding compound 40 is injected into the mold cavity 12. This involves back-injection molding of the decorative element 14, so that its rear side 24 comes into contact with the injection molding compound 40 or is bonded to it in a material-locking manner. During the injection of injection molding compound 40, the clamping elements 28s and 30s can be released or moved away. As already mentioned above, such a movement can be active (regulated or controlled) or passive (via the melt pressure).

[0066] Fig. 17 shows the removal of the finished injection-molded part 42 from the mold 16 or the injection molding device 10. The finished injection-molded part 42 has the decorative element 14 with design element 20 or decorative seam 20.

[0067] Using the injection molding devices 10, 100 presented here, it is possible to optimally arrange and align a decorative element 14, which not only has a uniform or similar surface but also contains at least one design element 20, in the injection molding device 10, 100. The position, shape, or orientation of the design element 20 is used as a reference to correctly position the decorative element 14 in the mold 16 prior to injection molding, in particular prior to back-injection with injection molding material. The decorative element 14 can be, for example, a textile made of natural and / or artificial fibers, a (plastic) film, a piece of leather, a piece of synthetic leather, or the like.The finished injection-molded part 42, in particular a decorative element 14 back-injected with injection-molding compound 40, can be part of a paneling of an interior of a motor vehicle, for example in the area of ​​a dashboard, a door panel, a handrest, a storage compartment lid and the like.
