The US 4,783,298 B discloses a method and apparatus for making a molded article having a cover layer on a molded component. The device in this case comprises an injection element having a pin which between an extended position in which the pin protrudes into the mold cavity and closes the injection element, a retracted position in which the pin releases an opening in the injection element and an intermediate position is movable ,

The DE 10 2012 024 056 A1 discloses a method for producing a trim part of a motor vehicle, consisting of a plastic body and connected to the plastic body and the visible surface of the plastic component forming decorative coating, wherein a consisting of a support layer and a decorative layer film section as part of a film web such between two open mold halves of an injection mold is arranged, that the decorative layer of the film portion facing away from a negative mold of the visible surface of the plastic component tool surface. According to the invention, it is provided that the plasticized plastic mass is injected from a side facing away from the decorative layer through an opening in the film section into the cavity arranged between the two mold halves of the injection mold. Furthermore, the invention relates to an injection mold for carrying out the method.

WO 2015/052291 A1 discloses an apparatus and method for making a molded article having a fiber reinforced backing and at least one associated plastic-containing attachment, the device including at least a first tool component and a second tool component, at least one of which is relatively movable to the other this way of inserting a fiber reinforced mat between respective embossing surfaces the two tool components can be opened and pressurized and pressed to close the mat, thereby producing the fiber-reinforced carrier, and wherein the second tool component has at least one nozzle for supplying liquefied plastic and the first tool component has at least one nozzle-side cavity for forming the attachment; wherein the second tool component has at least one nozzle-side cavity, so that the attachment can be manufactured and integrated by introducing plastic through the nozzle and through the mat into the nozzle-off-side cavity and the nozzle-side cavity and solidified therein.

In order to avoid splashing of the liquefied plastic or plastic melt and to be able to variably set a waiting time between the pressing of the mat and the beginning of the feeding of the liquefied plastic, a hole can be made in the mat at a gate. For this purpose, the nozzle may be a hot runner nozzle with a needle valve, through which the plastic is acted upon by pressure on the mat. The needle is previously movable by means of a hydraulic or pneumatic needle shutter drive and therefore can take two positions, namely a spray position in which the needle is withdrawn so far that an opening of a hot runner of the hot runner nozzle, from which the liquefied plastic can escape, for the plastic is released, and a punched position in which the needle projecting under closure of the opening so far over the associated tool component that it can penetrate into the mat to make the hole. When closing and subsequently opening the tool components, the needle is in its punched position to prevent fiber-reinforced material from penetrating the mat into the hot runner and to prevent solidified plastic associated with the mat from remaining in the hot runner. Consequently, the needle is in the closed state over and pierces the punch hole in the support or in the mat during the closing of the tool component. This results in the risk of tearing the wearer or the mat. Furthermore, there is the disadvantage that a blind hole remains there in the carrier where the needle was received with closed tool components. Also occurs the disadvantage that the hot runner nozzle must be arranged in the direction of a movement of the tool components in order to avoid an undercut in the support by the projecting needle when opening the device.

It is the object of the present invention to at least partially overcome the disadvantages of the prior art.

This object is achieved according to the features of the independent claims. Preferred embodiments are in particular the dependent claims, the description and the drawings removed.

The object is achieved by a device for producing a molded part with a fiber-reinforced carrier and at least one attached, plastic-containing attachment, wherein the device has at least two tool components, of which at least one tool component is movable relative to the other tool component and the device on this Open way to insert a fiber-reinforced mat and put under pressure and pressing the mat can be closed in a pressing position, so that the fiber-reinforced carrier can be produced. At least one tool component has at least one hot runner nozzle with a needle valve for supplying liquefied plastic and the other tool component at least one cavity for forming the attachment, so that the attachment can be produced and integrated by plastic through the nozzle and through the carrier into the cavity and introduced is solidifiable in it. In the hot runner nozzle, a needle is arranged, which via an electric drive, which is controlled via a control unit, at least in the pressing position between a spray position in which the needle is retracted so far that an opening of a hot runner of the hot runner nozzle, from which the liquefied plastic can emerge, is released, a punching position in which the needle preferably protrudes under closure of the opening so far on the associated tool component that they can penetrate into the mat, and intermediate position can be brought, in which they closed the opening no more than flush is arranged or advanced to the associated tool component.

In the intermediate position of the hot runner can thus be closed without the needle protrudes. Consequently, the carrier or the mat can be prevented from tearing when closing the tool components on the needle. It can also be avoided that a blind hole remains in the carrier. Further occurs when opening the device no undercut more, which allows a particularly flexible arrangement of the hot runner nozzle.

The intermediate position can also be referred to as a neutral position or middle position.

The electromotive drive of the needle can be designed as an electric motor or electric servomotor for lifting the needle. This provides the advantage that the movement of the needle is practically arbitrarily adjustable, especially with respect to a stroke of the needle which determines the position of the needle tip.

It is a development that the needle protrudes so far in the punching position that it can penetrate the mat. It is a special development that the needle protrudes so far in the punching position that it penetrates or dips into an opposite cavity of the other tool component.

A position of the needle which is "not more than flush with the associated tool component" can be understood in particular to mean a position in which a needle point of the needle terminates flush with a surface of the associated tool component ("flush position"). In particular, for this purpose, it is advantageous that the needle tip is a flat needle tip. It can, however, e.g. also be slightly concave or convex. However, a position of the needle "not more than flush with the associated tool component" can also be understood as meaning a position in which the needle tip is withdrawn into the hot runner nozzle or into the hot runner, but without releasing the hot runner for the passage of the liquefied plastic. This position may also be referred to as a "slightly retracted position".

The needle can therefore occupy at least three positions, which differ by the position of the needle or the associated needle tip. In principle, however, the needle can also assume further positions, e.g. several intermediate positions and / or multiple punched positions. It is a development that a position of the needle or the associated needle tip is arbitrary.

It is an embodiment that at least one hot runner nozzle is arranged at an angle between 15 to 70 degrees, in particular 30 to 60 degrees to a Verfahrbewegungsachse the tool components. This is made possible by allowing the tool components to be closed and opened without the needle (located in the intermediate position) projecting into the space between the two tool components. Thus, it can also be avoided that upon opening of the device, the protruding needle causes an undercut in the mat.

It is a further embodiment that the control unit is designed to control the electromotive drive such that a movement speed of a needle movement between punching position and / or intermediate position and / or spraying position is variable. In particular, so variable opening and / or closing speed of the needles can be adjusted. As a result, for example, pressure peaks and / or overspraying can be improved avoided. The movement speed of the needle may even be variable within a movement process.

Furthermore, it is advantageous if the control unit is designed to determine a needle position of the needle with the aid of the electric motor drive. This can be realized, for example, by storing a reference position of the needle in a memory in the control unit, wherein the control unit calculates from the reference position all remaining positions of the needle, for example, from how long and at which speed the control unit controls the needle or emotional.

It is a further advantage of an electric motor driven needle that it allows particularly large needle strokes, so that the mat can be pierced particularly safe, even with a wrinkling and / or a partially high basis weight of the mat. This can therefore be achieved particularly reliably that the cavity is completely filled. In addition, a sufficiently deep immersion of the needle into the cavity can thereby be ensured, for example, in order to be able to introduce a material volume of the mat ("stamping waste") punched out in a particularly reliable manner into the cavity for producing the punched hole.

It is a particularly achievable using an electric motor needle drive configuration that the needle in the punched position protrudes up to 20 mm or can be advanced. It can or is advantageously advanced 2 mm to 7 mm.

It is also advantageous if the control unit is formed the punching position and / or the intermediate position and / or the injection position of the needle ( 6 ) to adjust. In other words, the control unit can control the needle or the electromotive drive in such a way that the individual defined positions of the needle can be adjusted during operation of the device. This may be necessary, for example, if the needle has signs of wear and / or fluctuations in the composition of the plastic or the mat occur. The control unit can therefore be designed to control the electromotive drive such that the needle movement (needle stroke, needle speed, etc.) is adjustable depending on a property of the mat and / or on a property of the liquefied plastic.

Furthermore, it is advantageous if the cavity is at least partially disposed opposite to the hot runner nozzle and the needle is at least partially disposed in the cavity at least in the punching position. That way is it is easily possible that the needle can punch the mat pressed to the carrier as clean as possible, since the needle can move through the carrier into the cavity.

It is also an embodiment that the cavity, at least in a region in which the needle is arranged at least in the punched position in the cavity, has a, in particular circular, bulge. Under bulge can be understood in this context, that the cavity is laterally circular bulged. The bulge can for example be part of a filling rib, so that for example a groove can run through the bulge. The bulge allows the needle to safely exchange into the fill rib and reliably perform die cutting if the fill rib is otherwise narrower than a cross-sectional dimension (e.g., a diameter) of the needle.

The shape of the cavity is not limited in principle. The cavity can be provided in a replaceable or movable tool element, so that by simple conversion of the tool various attachments, e.g. Various decorative element carrier or decorative elements can be produced. The cavity can also serve as a template to allow a clean punching.

It is also an embodiment that a diameter of the protrusion is 0.05 to 1 mm larger than a diameter of the needle ("needle diameter"). Thus, a reliable immersion of the needle can be achieved with a sufficiently tight clearance for precise punching of the punching waste. The punching waste can also be introduced so particularly reliable in the Füllrippe.

It is a development that the needle diameter is between about 1 and 3 mm.

The needle is advantageously cylindrically shaped in order to achieve an exact punching and a flush component termination. The front, free end face may e.g. be flat, convex or concave.

It is still a further development that the plastic comprises a polymer, preferably PP, ABS, PC / ABS, PA. In particular, fillers and / or reinforcing materials such as PP T20 etc. may be added to the polymer.

It is also a development that the mat is a thermosetting or duroplastic fiber system with natural fibers, glass fibers, mineral fibers, synthetic fibers, cellulose fibers and / or carbon fibers. In particular, the mat may be a NFPP mat, that is, natural fibers as a fibrous material and polypropylene as a matrix or support material. Natural fibers are characterized by a high specific strength and rigidity, while at the same time 10 to 30 percent lower weight compared to glass fiber reinforced plastics. Nevertheless, their technical characteristics are comparable and their life cycle assessment is favorable.

It is also a development that the mat is preheated or preheatable, preferably to a temperature between 100 ° C and 300 ° C, in particular between 180 ° C and 220 ° C, either outside the tool or by means of an integrated heater in the tool. This simplifies the shaping of a three-dimensional contour and possibly the connection with the plastic to be sprayed through. The heated mat is positioned between the open tool components and fixed if necessary. The fixation can be done by means of a clamping frame, clamps or pins, etc.

It is also a development that a tool component is provided stationary, while the other tool component is movable. In this case, the movable tool component preferably has one or more cavities and no nozzle, and the other stationary tool component has one or more nozzles but no cavity. The provision and supply of the plastic is easier to accomplish by the stationary tool component, while an ejection of the attachments on the movable side is low.

The device can basically analogous to those in DE 10 2011 005 350 A1 and or WO 2015/052291 A1 be further developed described items.

The object is also achieved by a method for producing a molded part with a fiber-reinforced carrier and at least one attached, plastic-containing attachment. The method includes inserting a fiber reinforced mat between two tool components that are in an open state, wherein one tool component has at least one hot runner nozzle for supplying liquefied plastic and the other tool component has at least one cavity for forming the attachment and one located in the hot runner nozzle Needle is in an intermediate position. Further, the method includes the step of closing the tool components so that the mat is pressurized and pressed to make the fiber reinforced backing while the needle is still in the intermediate position. This is followed by a step of punching the carrier by moving the needle from the Intermediate position in a punched position, so that at least one punched hole is formed in the carrier. Furthermore, the method comprises the step of producing the attachment to the carrier by the needle is moved into the injection position and plastic is introduced through the hot runner nozzle and through the punch opening into the cavity and solidified there.

The method can be designed analogously to the device and gives the same advantages.

It is advantageous at this point if the step of punching the carrier takes place immediately after the step of closing the tool components. The step of punching is preferably carried out only when the mat was pressed to the carrier. Up to this moment, the needle is particularly preferably in the intermediate position.

It may be advantageous if, prior to the step of manufacturing the attachment, a step of cooling the carrier takes place. The cooling can be done actively by, for example, the tool components have active or passive cooling elements, which are suitable for cooling the carrier. However, the cooling can also take place in that by convection of the carrier gives off heat to the tool components, so that cooling is realized by a waiting time in which the carrier emits heat to the tool components. By cooling, the carrier solidifies, so that the risk of over-molding during the step of manufacturing the attachment can be reduced.

Furthermore, it may be advantageous if the needle is moved from the injection position to the intermediate position after the step of producing the attachment. Preferably, the tool components are still closed. The movement of the needle back into the injection position can be followed by pressing the plastic into the cavity, which contributes to the fact that the plastic is distributed as completely as possible in the cavity. At the same time can be prevented so that too large injection point is formed on the carrier.

The above-described characteristics, features and advantages of this invention, as well as the manner in which they are achieved, will become clearer and more clearly understood in connection with the following schematic description of an embodiment which will be described in detail in conjunction with the drawings.

1 shows a movable tool component 1 and a stationary tool component 2 , These two tool components 1 . 2 are thus relatively movable relative to each other and indeed in a Verfahrbewegungsachse V perpendicular to each other.

The tool components 1 . 2 are as shaped elements with stamping surfaces 3 and 4 formed and have such a shape that during compression of the embossing surfaces 3 and 4 one between the stamping surfaces 3 and 4 inserted fiber mat F takes the form of a desired support element. The fiber mat F can be present in particular as a thermosetting or duroplastic fiber composite system, for example as a NFPP mat.

The stationary tool component 2 has a hot runner nozzle 5 with needle valve, which is suitable to pressurize a hot molten plastic material against the pressed to the carrier T fiber mat F by pressure. Are the two tool components 1 . 2 still open or separated from each other, there is a needle 6 the hot runner nozzle 5 in an intermediate position, in which a flat needle point 7 the needle 6 with the associated embossing surface 4 flush. The needle closes 6 an opening 8th a hot runner 9 , The needle 6 is along its longitudinal extent by means of an electric servomotor 10 drivable. The hot runner nozzle 5 is aligned in traversing axis V, ie, that its needle 6 along or parallel to the Verfahrbewegungsachse V is linearly movable.

Additionally, at the stationary tool component 2 another hot runner nozzle 11 present, which is oriented at an angle of approximately 20 degrees to the movement axis V, ie that its needle 6 is linearly movable obliquely to the Verfahrbewegungsachse V. The hot runner nozzle 11 is in the range of a side wall of the embossing surface 4 arranged.

At the tool component 1 are the hot runner nozzles 5 and 11 opposite, respectively associated cavities 12 respectively. 13 , The cavities 12 and or 13 also serve as matrices.

2 shows the device 1 in a closed state in a pressing position. In the closed state, the fiber mat F is pressed to the fiber-reinforced carrier T. The hot runner nozzles 5 and 11 are still in the intermediate position.

After a waiting time between eg 0 s and 30 s the needle becomes 6 at least the hot runner nozzle 5 moved into a punching position, as in 3 shown. The needle penetrates 6 the carrier T and penetrates or dives into the associated cavity 12 one. Thus, in the carrier T is a punch hole 14 generated. A punched punching waste S is by means of the needle 6 completely in the cavity 12 inserted. This can be done by the needle 6 by means of the electric servomotor 10 For example, be extended between three and eight millimeters, but also up to 20 millimeters.

4 shows the device in the closed state, in which the needle 6 the hot runner nozzle 5 has been withdrawn into a spray position and so the opening 8th for the passage of the liquefied plastic releases. In this spray position can therefore hot, pressurized plastic melt through the hot runner 9 to the opening 8th be promoted and then out of the opening 8th escape. The liquefied plastic flows through the punch hole 14 into the cavity 12 , so that the punching waste S is shed with. Also, the plastic connects with the carrier T. Because with the injection of the plastic by the carrier T is not only a firm connection, which takes place on a mechanical Hinterkrallung the solidified attachment with the carrier T, but also a solid compound on a compound of the respective plastic materials, since both are in a still viscous, connectable state in the manufacturing process. After cooling the product, therefore, an excellent integrity of the attachments is created with the fiber-reinforced carrier T. In this way, therefore, an attachment on one side of the carrier T is created, which can be referred to as a back, formed. The cavity of the cavity 12 corresponds to the shape of the attachment. The cavity 12 can be provided in a replaceable or movable tool element, so that by simple conversion of the tool various attachments, and thus various decorative element carrier or decorative elements can be produced.

In a further step, the needle becomes 6 moved back to the intermediate position. After a waiting period, the tool components can 1 . 2 then open and the carrier T and attachment (s) are removed.

5A shows in plan view a section of the first tool component 1 in the area of the cavity 12 in the form of a filling rib 15 , 5B shows the fill rib 15 as a sectional view with a view of a sectional plane AA 5A , This rib 15 is in the form of a longitudinal groove of constant width in the embossing surface 3 brought in. So that the needle 6 in the filling rib 15 must be able to dip a width of the fill rib 15 larger than a diameter of the circular cross-section, for example, needle 6 , This can increase the width of the fill rib 15 as desired.

6A shows in plan view a section of the first tool component 1 in the area of the cavity 12 in the form of a filling rib 16 , 6B shows the fill rib 16 as a sectional view with a view of a sectional plane BB 6A , This rib 16 is in the form of a longitudinal groove in the embossing surface 3 introduced, but has a dip area in the form of a lateral in plan view bulge 17 on. The needle 6 can in the bulge 17 plunge. The bulge 17 has a diameter D that is 0.1 mm larger than a needle diameter of the needle 6 is on. The needle 6 has a diameter of three millimeters. With the help of the bulge 17 can the needle 6 also in a filling rib 16 immerse, which is partially narrower than the needle 6 ,

Of course, the present invention is not limited to the embodiment shown.

So in addition to the hot runner nozzles 5 and 11 and / or cavities 12 and 13 further nozzles and / or cavities may be present. By providing cavities on both sides and nozzles on both sides, add-on parts or plastic decorative layers can be provided on both sides of the fiber mat F. In this case, it is conceivable to form on the front side of the fiber mat F a decorative layer with plastic injected from the rear side or plastic acted upon from the front side. In a first manufacturing step, the fiber mat F, for example, between the tool components 1 and 2 brought and possibly on one of the two tool halves 1 and 2 fixed become. The temperature of the fiber mat F may be increased in advance or with a heating device which may be in one or both of the tool components 1 . 2 is integrated.

Through the in 2 shown pressing the fiber mat F is solidified to the carrier T and determines the three-dimensional contour of the trainees T to be formed.

Furthermore, with the collision of the two tool components 1 . 2 a cutting / pitting edge act on the fiber mat F, so that a contour cut or a trimming of a breakthrough can be performed.

During or after the molding process is completed, with closed tooling components 1 . 2 via the heating channel nozzle (s) 5 . 11 a plastic melt is introduced, which penetrates the carrier T and the still open cavity 12 respectively. 13 crowded.

In addition, further operations, such as cutting, final molding, laminating and the like, are performed.

Generally, "on", "an", etc. may be taken to mean a singular or a plurality, in particular in the sense of "at least one" or "one or more" etc., unless this is explicitly excluded, e.g. by the expression "exactly one", etc.
