Description

[0001] Insert for a molded body made of an injectable mass, molded body and method for producing an insert

[0002] The present invention relates to an insert for a molded body made of an injection-moldable molding compound, comprising a strip-shaped base body made of a metal having a plurality of widened slots, wherein the slots are arranged in rows extending in a longitudinal direction of the strip. Furthermore, the invention relates to a molded body made of an injection-moldable molding compound having at least one such insert, as well as a method for producing such an insert.

[0003] An insert of the type mentioned above is used to reinforce a molded body made of an injection-moldable molding compound, such as an edge protection strip made of an elastomeric material. Such an edge protection strip is used for openings in a vehicle, such as a window opening, a door opening, or a tailgate opening.

[0004] To secure the edge protection strip, the opening is provided with a flange surrounding the opening, onto which the edge protection strip is clipped or clamped. For this purpose, the insert is formed into a V-profile I or U-profile.

[0005] To produce an edge protection strip, the insert, formed into a V-shaped or U-shaped profile, is coated with an injection-moldable molding compound, such as a plastic and / or an elastomer, in an extrusion process. To allow the injection-moldable molding compound to penetrate, the insert is provided with slits. The slits are punched into the base body in a continuous manufacturing process. An insert produced by punching has high tear resistance but has the disadvantage of generating waste during production.

[0006] EP 1 693 237 B1 discloses a metal strip as an insert for decorative or sealing strips made of flexible material, which is provided with a plurality of wedge-shaped or internally wedge-shaped edge slits arranged successively in the longitudinal direction of the strip and extending inwards from one edge of the metal strip transversely to its longitudinal direction, and metal slits arranged longitudinally between successive edge slits, also extending transversely to the longitudinal direction of the metal strip but not extending to the edge, which end in a point at both ends. The edge slits and the central slits are designed to overlap one another in the transverse direction of the metal strip. The edge slits and the central slits are cut and widened by rolling. However, the rolling process alters the metal strip dimensional and technologically.

[0007] The present invention is based on the object of creating an insert, a molded body and a method in the production of which waste is avoided and which at the same time avoids a technological change in the band.

[0008] To solve the problem, an insert having the features of claim 1, a shaped body having the features of claim 8 and a method having the features of claim 13 are proposed.

[0009] Advantageous embodiments of the insert and the molded body are the subject of the respective dependent claims.

[0010] According to a first aspect of the invention, an insert for a molded body made of an injection-moldable molding compound, in particular for a sealing strip or for an edge protection strip, is proposed. The insert comprises a strip-shaped base body made of a metal having a plurality of widened slits, wherein the slits are arranged in rows extending in a longitudinal direction of the strip, wherein the rows are spaced from one another in a transverse direction of the strip and offset from one another in a longitudinal direction of the strip. By offsetting the rows, in particular the slits of the opposite rows, in the longitudinal direction of the strip, it is possible to produce the slits by means of rotary cutting and to widen them by stretching, i.e. by pulling the base body in the longitudinal direction of the strip. This eliminates waste during production.Furthermore, since the base body is not rolled to widen the slots, but stretched in the longitudinal direction of the strip, no geometric or technical weakening or modification is added to the insert. The reason for this is that the arrangement of the lamellae resulting between the slots follows the naturally preferred shear direction of the grains of the respective metal and thus takes advantage of the natural offset, particularly of the slip planes, in the lattice structure of the respective metal. The widening or opening of the slots can be created by stretching without any dimensional and / or technological changes to the raw strip. It is therefore no longer necessary to add any geometric or technical weakening or modification to the insert by means of track rolling. This makes the insert a fully-fledged direct replacement for a stamped strip.

[0011] In this context, an offset is understood to be the distance between the center lines of two diagonally opposite slots in the offset rows along the longitudinal direction of the insert or base body. This means that the center lines of two diagonally opposite slots are not aligned in a straight line, but rather are parallel and spaced apart in the longitudinal direction of the insert. In this context, a center line is understood to be the axis of symmetry of a slot.

[0012] Advantageously, the rows, especially the slots in the rows, are offset from one another in the longitudinal direction of the insert or base body. This means that the center lines of the diagonally opposite slots do not lie on a common straight line, but are offset from one another in the longitudinal direction of the insert and are spaced apart.

[0013] The insert can also be referred to as an inlay tape, reinforcement tape, scaffold tape, carrier tape, or reinforcement. The molded body can be a sealing strip, a decorative strip, or an edge protection strip for a vehicle, into which the insert is embedded to reinforce the molded body. The injection-moldable molding compound can be a plastic and / or an elastomeric material.

[0014] The base body can have a thickness between 0.2 mm and 1.5 mm, in particular between 0.3 mm and 1 mm, furthermore in particular between 0.4 mm and 0.6 mm, furthermore in particular between 0.41 mm and 0.47 mm, furthermore in particular between 0.43 mm and 0.46 mm. Due to the low thickness, the insert is lightweight. Furthermore, the base body can have a width B between 15 mm and 60 mm, in particular between 20 mm and 45 mm.

[0015] The slots introduced into the base body can be open on the outside of the band, i.e. the edge slots do not have a fixed border at the edges of the base body, or the slots can be closed, i.e. the slots have a fixed border.

[0016] Advantageously, the base body has at least one continuous web extending in the longitudinal direction of the strip, with the slots extending perpendicularly from the web. To widen the slots, the base body can be stretched in the longitudinal direction of the strip after the slots have been introduced by pulling the base body, in particular the web.

[0017] Furthermore, the base body advantageously has slats between the slots that extend perpendicularly from the web. When the insert is formed, the slats engage around a flange of an opening and apply the clamping force. The slats can be arranged overlapping or offset from one another in the longitudinal direction of the strip.

[0018] To ensure that the edge protection strip optimally adapts to the shape of the opening, the web formed between two diagonally opposed slits can be broken transversely across the strip after the insert has been overmolded with an injection-moldable molding compound. Since the diagonally opposed slits are offset longitudinally along the strip, a fracture line created when the web is broken can run diagonally to the strip's longitudinal direction. This means that the fracture line forms an angle with a longitudinal and / or transverse strip axis.

[0019] In an advantageous embodiment, the center lines of the diagonally opposite slots in the offset rows have an offset of between 1% and 50% in the longitudinal direction of the strip. The offset of the center lines of the diagonally opposite slots makes it possible to create the slots by rotary cutting and to widen them by stretching or pulling the base body in the longitudinal direction of the strip. A center line is understood here to be the axis of symmetry of a slot. The percentage advantageously indicates the distance between the center lines of two diagonally opposite slots in the offset rows in the longitudinal direction of the strip. The center lines of two diagonally opposite slots in the offset rows advantageously have an offset of between 1% and 50%.The offset, or spacing, specified as a percentage, can be calculated as follows: a distance resulting from the distance between the centerlines of two slots in a row that immediately follow one another in the longitudinal direction of the belt, divided by the distance resulting from the distance between the centerlines of two diagonally opposite slots in the longitudinal direction of the belt whose endpoints are the shortest distance from one another. Thus, an offset of 40% means that for a distance of, for example, 10 cm, which corresponds to the distance between the centerlines of two immediately consecutive slots in a row in the longitudinal direction of the belt, the offset, or spacing, corresponding to the distance between the centerlines of two diagonally opposite slots in the offset row in the longitudinal direction of the belt is 4 cm.Furthermore, the center lines of two diagonally opposite slots of the offset rows advantageously have an offset in the longitudinal direction of the strip of between 10% and 40%.

[0020] By offsetting the center lines, a straight line through the end points of two diagonally opposite slots that are as close as possible to each other can enclose an angle with a perpendicular running in the transverse direction of the strip, which preferably corresponds to the center line of the slot. The angle can be between 10° and 80°. When the slots are widened by pulling the base body in the longitudinal direction of the strip, all the grains move in the direction of the angle. Thus, the straight line or the inclination of the straight line determined by the angle forms the sliding line for the metal grains, along which the grains move when the base body is stretched or pulled in the longitudinal direction of the strip to widen the slots. The harder the metal of the base body, the flatter the angle, and the softer the metal of the base body, the steeper the angle.The 'shortest distance' is defined as the distance between the ends of the diagonally opposite slots. The end point, in this case, is the lowest point of the slot as seen from the outside of the belt, or the reversal point of the slot geometry, or the inflection point of the slot geometry, i.e., the point at which the graph of the slot geometry changes its curvature.

[0021] In an advantageous embodiment, the base body has at least two first rows of first slots arranged offset from one another in the longitudinal direction of the strip, wherein the first slots extend inward from edges of the base body in the transverse direction of the strip. Thus, the base body has two rows arranged offset from one another, the rows of which are diagonally opposite one another. The slots introduced into the base body can also be referred to as edge slots because they extend inward from the edges of the base body transversely to the longitudinal direction of the strip. Advantageously, the edge slots are open on the outside of the strip, i.e., the edge slots do not have a fixed border at the edges of the base body.

[0022] Advantageously, the first slots have a length L corresponding to approximately 1 / 3 of the width B of the base body 16. The slots of the rows can have different lengths, i.e., the slots of the rows can be asymmetrical. For example, the edge slots of a first row can have a first length, and the edge slots of a second row can have a second length. It is also conceivable that, with three or more rows, each row can have different slot lengths.In an advantageous embodiment, the base body has two first rows of first slots that are opposite one another and extend inwardly from edges of the base body in the transverse direction of the strip, and the base body has a second row of second slots that is arranged between the first rows and spaced from the first rows in the transverse direction of the strip, which are offset from the first slots in the longitudinal direction of the strip and extend in a central section of the base body in the transverse direction of the strip. The base body thus has three rows, with the slots opposite one another at the edges of the base body, i.e., their center lines are coaxial with one another. The second slots of the second row are offset from the first slots of the first rows, i.e., the center line of the second slots is offset from the center lines of the first slots. The second slots are introduced in a central section of the base body.The second slots can therefore also be referred to as center slots, inner slots, or internal slots. Advantageously, the second slots are closed, meaning they have a solid border.

[0023] Advantageously, the first slots have a length L that corresponds approximately 1 / 8 of the width B of the base body 16. Furthermore, the second slots advantageously have a length L that corresponds approximately 1 / 2 of the width B of the base body 16. Advantageously, the first slots can have the same length or different lengths.

[0024] In an advantageous embodiment, the base body has two first rows with first slots and n second rows with second slots. Where n corresponds to an integer. The first slots and / or the second slots can have the same length or different lengths. In an advantageous embodiment, a web is formed between every two rows spaced apart in the transverse direction of the strip. If the base body has two rows arranged offset from one another, then the base body has one web. If the base body has three rows, then a web is provided between every two offset rows, i.e. in this case the base body has two webs. Thus, with n rows, the base body has n-1 webs. Where n corresponds to an integer. In an advantageous embodiment, the web has a width of between 1 mm and 10 mm. This gives the strip sufficient strength.

[0025] In an advantageous embodiment, the slots are created in the base body by means of rotary cutting. In rotary cutting, which can also be referred to as a rolling cutting process or rotary cutting process, slots are created in the base body using a rotating cutting wheel.

[0026] In an advantageous embodiment, the metal strip is smoothed across its entire width after cutting. The rotary cutting process creates raised areas in the area of ​​the slits. The subsequent smoothing restores the metal strip to its original thickness.

[0027] In an advantageous embodiment, the slots are widened by stretching the base body. After slitting, the base body is stretched in the longitudinal direction of the strip, particularly along the web. This widens the slots, for example, to form openings or perforations.

[0028] In an advantageous embodiment, the widened slots have an opening width between 0.1 mm and 4 mm. Furthermore, the opening width of the slots is advantageously between 0.2 mm and 1.2 mm.

[0029] In an advantageous embodiment, the slots taper inward in a pointed, wedge-shaped, and / or rounded manner. Advantageously, the slots are open on the outside of the band, meaning that the slots do not have a closed border at the edges of the base body. Alternatively, the slots can be designed as openings with a closed border, meaning that the slots have a closed contour. The closed contour can be diamond-shaped, hexagonal, and / or slot-shaped.

[0030] According to a further aspect of the invention, a molded body made of an injection-moldable molding compound is proposed. The molded body has at least one insert according to the invention. The insert is advantageously formed into a V-shaped, U-shaped, or S-shaped profile. In an advantageous embodiment, the molded body is made of a plastic and / or an elastomeric material. The molded body can be produced by injection molding or extrusion. For this purpose, the insert is formed into a V-shaped or U-shaped profile, in particular bent, and then overmolded with a plastic or an elastomeric material. The plastic and / or the elastomeric material advantageously forms a sheath.

[0031] In an advantageous embodiment, a web of the base body is broken between at least two slots located opposite one another in the transverse direction of the strip and offset in the longitudinal direction of the strip. This allows the shaped body to adapt to the shape of the opening during installation. The web is advantageously broken at the shortest distance between two diagonally opposite slots. The web is advantageously broken along the longitudinal direction of the strip at the shortest distance between all diagonally opposite slots. Furthermore, the shortest distance corresponds to a fracture line that runs diagonally to the longitudinal direction of the strip. This means that the fracture line forms an angle with the longitudinal axis of the strip and / or the transverse axis of the strip.

[0032] In an advantageous embodiment, the molded body is a decorative or sealing strip or an edge protection strip. The molded body can have a sealing lip and a mounting slot for attaching the molded body to a flange surrounding an opening. The insert, formed into a V-profile I or a U-profile, is advantageously embedded in the mounting slot.

[0033] According to a further aspect of the invention, a method for producing an insert according to the invention is proposed. In the method, a strip-shaped base body made of a metal is first provided. Slits are then cut into the base body by rotary cutting, and the base body is then stretched in the longitudinal direction of the strip to widen the slits.

[0034] Advantageously, the slots are created by rotary cutting such that the slots are arranged in rows extending in the longitudinal direction of the strip, with the rows being spaced apart from one another in a transverse direction of the strip and offset from one another in a longitudinal direction of the strip. Furthermore, a web is advantageously formed between each two rows spaced apart in the transverse direction of the strip.

[0035] Advantageously, the base body is pulled lengthwise along at least one web formed between two rows in the longitudinal direction of the strip in order to widen the slots.

[0036] Below, an insert and an edge protection strip, as well as other features and advantages, are explained in more detail using exemplary embodiments, which are schematically illustrated in the figures. Here:

[0046] Fig. 9 is a plan view of the insert formed into a U-profile of Fig. 7; Fig. 10 is a perspective view of a molded body with a cutout and the insert shown in Fig. 7; and

[0047] Fig. 11 is a side view of the molded body of Fig. 10.

[0048] Figures 1 to 3 show a first embodiment of an insert 10, which serves to reinforce a molded body 12 shown in Figures 4 and 5. The molded body 12 is in this case an edge protection strip 14 for an opening, such as a window opening, a door opening, or a tailgate opening, of a vehicle (not shown).

[0049] The insert 10 comprises a band-shaped base body 16 made of a metal, which has a width B between 15 mm and 60 mm, in particular between 20 mm and 45 mm, and a thickness between 0.2 mm and 1.5 mm, in particular between 0.4 mm and 0.6 mm, furthermore in particular between 0.41 mm and 0.47 mm, furthermore in particular between 0.43 mm and 0.46 mm.

[0050] The base body 16 has a plurality of lamellae 18 and widened first slots 20, with a web 26 extending in a strip longitudinal direction LB between the opposing lamellae 18 and slots 20. The lamellae 18 have a width between 2.5 mm and 4.5 mm.

[0051] As can be seen in Fig. 1, the widened first slots 20 are arranged periodically one after the other in first rows 22 in a strip longitudinal direction LB, wherein the first rows 22 are spaced apart from one another in a strip transverse direction QB and offset from one another in a strip longitudinal direction LB.

[0052] As can be seen in Fig. 1, the first slots 20 extend inward from edges 24 of the base body 16 transversely to the strip longitudinal direction LB. Center lines Mi of the diagonally opposite first slots 20 of the mutually offset rows 22 have an offset V in the strip longitudinal direction LB of between 1% and 50%.

[0053] Due to the offset V of the center lines Mi, a straight line G passing through endpoints 27 of two diagonally opposite first slots 22, which are at a shortest distance A from each other, forms an angle a with a perpendicular S running in the transverse strip direction QB, which corresponds to the center line Mi. The angle a is between 10° and 80°. The inclination of the straight line G, determined by the angle a, forms a sliding line for the metal grains, along which the grains move when the base body is stretched or drawn in the longitudinal strip direction LB to widen the slots 22.

[0054] The widened first slots 20 have an opening width between 1 mm and 4 mm and a length Li that corresponds approximately to 1 / 3 of the width B of the base body 16. The first slots 20 are rounded inwardly and are open on the outside of the band, i.e., the first slots 20 do not have a fixed border at the edges 24. In an embodiment not shown, the slots can also be asymmetrical, i.e., the first slots 20 at one of the edges 24 have a first length and the first slots 20 at the opposite edge 24 have a length that differs from the first length.

[0055] To produce the widened first slots 20, the slots 20 are introduced into the base body 16 by rotary cutting, which can also be referred to as rotary cutting or roll cutting, using a rotating cutting wheel. After slitting, the base body 16 is drawn lengthwise in the strip's longitudinal direction LB, thereby widening the slots 20.

[0056] Figures 4 and 5 show the molded body 12 designed as an edge protection strip 14. The molded body 12 has a casing 28 made of a plastic and / or elastomeric material, into which the insert 10, formed into a V-shaped or U-shaped profile, is embedded. The casing 26 comprises a plug-in shaft 30 and two sealing lips 32 projecting into the plug-in shaft. By means of the plug-in shaft 30, the molded body is plugged onto a flange surrounding an opening of a vehicle (not shown). The insert 10 provides the necessary clamping force. To produce the molded body 12, the insert 10 is formed into a V-shaped or, as shown in Figures 2 and 3, a U-shaped profile and then overmolded with an injectable molding compound, such as a plastic and / or an elastomeric material, for example by injection molding or extrusion.

[0057] To ensure that the edge protection strip 14 can optimally adapt to the shape of the opening, after the insert 10 has been overmolded with an injection-moldable molding compound, the web 26 is broken between two diagonally opposite first slits 20. Since the diagonally opposite first slits 20 are offset in the strip longitudinal direction LB, a break line 34 runs diagonally to the strip longitudinal direction LB. This means that the break line 34 forms an angle with a strip longitudinal axis LB and / or a strip transverse axis QB.

[0058] A second embodiment of the insert 10 is described below, wherein the same reference numerals are used for identical or functionally identical parts.

[0059] The second embodiment of the insert 10 shown in Figures 6 to 9 differs from the first embodiment in that the base body 16 has two first rows 22 with first slots 20 and a second row 36 with second slots 38 arranged between the first rows 22 and offset from the first rows 22 in the transverse direction QB of the strip and in the longitudinal direction LB of the strip, wherein a web 26 is formed between each of the first rows 22 and the second row 36.

[0060] The first slots 22 are rounded inwards and are open on the outside of the band, i.e. the first slots 20 have no fixed border at the edges 24, wherein the first slots 22 of the first rows 20 lie opposite one another, i.e. their center lines Mi are aligned coaxially with one another. The widened first slots 20 have an opening width of between 1 mm and 4 mm and a length Li which corresponds to approximately 1 / 8 of the width B of the base body 16. As can be seen in particular in Figs. 6 and 7, the second slots 38 extend in a central section 40 of the base body 16, wherein the second slots 38 are closed, i.e. the second slots 38 have a fixed border. The second slots 38 are offset from the first slots 20, i.e. the center lines M2 of the second slots 38 are offset from the center lines Mi of the first slots 20 in the belt longitudinal direction LB.In addition, the second slots 38 have a length L that is greater than the length L of the first slots. The second slots 40 are rounded at their ends, as can be seen in the figures. The widened second slots 38 have an opening width between 1 mm and 4 mm and a length L2 that corresponds approximately to 1 / 2 the width B of the base body 16.

[0061] Figures 10 and 11 show the molded body 12 formed as an edge protection strip 14, which has the insert 10 according to the second embodiment. Otherwise, the edge protection strip 14 corresponds to the edge protection strip 14 shown in Figures 4 and 5 and described above.

[0062] As can be seen from a summary of Figures 7 to 11, in order to adapt the edge protection strand 14 to the course of an opening, the webs 26 between two diagonally opposite first and second slots 20, 38 are broken.

[0063] The insert 10 is characterized by the rows 22, 36 and slots 20, 38 offset in the longitudinal direction LB of the strip. This allows the slots 20, 38 to be created by rotary cutting and widened by stretching the base body 16 in the longitudinal direction LB of the strip. As a result, no waste is generated during the production of the insert 10, and furthermore, no geometric or technical weakening or modification is added to the insert 10. This is because the arrangement of the lamellae 18 resulting between the slots 20 follows the naturally preferred shear direction of the grains of the respective metal and thus utilizes the natural offset, in particular of the slip planes, in the lattice structure of the respective metal. The widening or opening of the slots 20, 38 is created without any dimensional and / or technological changes to the raw strip.It is therefore no longer necessary to add a geometric or technical weakening or modification to the insert 10 by means of track rolling.
