Description
Die Erfindung betrifft eine Reifenvulkanisierform mit mehreren zu einer umfangsmäßig geschlossenen Form zusammenfügbaren Profilsegmenten gemäß dem Oberbegriff des Patentanspruchs 1 sowie ein Verfahren zu deren Herstellung.The The invention relates to a Reifenvulkanisierform with several to one circumferentially closed Form joinable Profile segments according to the preamble of claim 1 and a method for its production.
In Reifenvulkanisierformen wird der auf den Reifenunterbau aufgebrachte Laufflächenstreifen aus Kautschukmaterial zu dem gewünschten Profil geformt und unter Wärmeeinwirkung zu Gummi vulkanisiert. Bei diesem Vorgang muss die zwischen Laufflächenstreifen und Formfläche vorhandene Luft abgeführt werden, um einwandfreie Ausformung des Reifenprofils zu gewährleisten.In Tire vulcanizing molds are applied to the tire casing Tread strip off Rubber material to the desired Profile shaped and under heat vulcanised to rubber. In this process, the between tread strip and molding surface existing air dissipated to ensure proper shaping of the tire tread.
Bekannte Reifenvulkanisierformen weisen hierfür einerseits in ihrer Formfläche mündende Entlüftungskanäle oder -bohrungen auf, welche andererseits direkt oder über weitere Entlüftungskanäle an einer Außenfläche der Form münden. Die Form besteht dabei üblicherweise aus mehreren umfangsmäßig zusammenfügbaren Profilsegmenten mit je einer Formfläche, die bei zusammengesetzten Profilsegmenten zusammen mit seitlichen Formwänden die Gesamtform bilden, aus der sich die äußere Kontur des Luftreifens ergibt.Known Tire vulcanizing molds have for this purpose on the one hand in their molding surface opening venting ducts or -bohrungen on the other hand directly or via further ventilation ducts on a Outer surface of the Form form. The form usually consists of this from several circumferentially joinable profile segments each with a molding surface, the composite profile segments together with lateral mold walls form the overall shape of the outer contour of the tire results.
Bei bekannten Profilsegmentsystemen werden die in der Formfläche der Profilsegmente mündenden Entlüftungskanäle durch gebohrte Ausnehmungen gebildet, in welche verschließbare Entlüftungsventile einsetzbar sind. Um eine ausreichende Entlüftung der Vulkanisierform, insbesondere auch in Nischen des Profils zu gewährleisten, muss eine Vielzahl solcher Entlüftungskanäle, üblicherweise zwei- bis dreitausend pro Vulkanisierform, vorgesehen werden. Dies führt zu einem erheblichen Kosten- und Zeitaufwand für die Herstellung der Reifenvulkanisierform.at known profile segment systems are in the molding surface of Opening up profile segments Venting channels through drilled recesses formed in which closable vent valves can be used. In order to ensure sufficient ventilation of the vulcanization mold, In particular, in niches of the profile to ensure a variety such venting channels, usually two to three thousand per Vulkanisierform be provided. This leads to a considerable cost and time required for the production of Reifenvulkanisierform.
Ein weiterer Nachteil bekannter Profilsegmentsysteme besteht darin, dass beim Ausvulkanisieren des Fahrzeugluftreifens Kautschukmaterial in die Entlüftungskanäle gepresst bzw. gesogen werden kann. Die dadurch entstehenden Austriebe bleiben auf dem fertigen Fahrzeugluftreifen erhalten und müssen vor dessen Verwendung mit eigens dafür vorgesehenen Maschinen entfernt werden. Dieses sogenannte Trimmen führt zu einer Verlängerung und Verteuerung des Herstellungsprozesses des Fahrzeugluftreifens.One Another disadvantage of known profile segment systems is that that during vulcanization of the pneumatic vehicle tire rubber material pressed into the ventilation channels or can be sucked. The resulting shoots remain get on the finished pneumatic vehicle tire and need to its use with specially designed Machines are removed. This trimming leads to a Extension and Price increase of the manufacturing process of the pneumatic vehicle tire.

Die Abfuhr von Luft aus der Reifenvulkanisierform ist jedoch nur eines einer Reihe von Problemen, mit denen sich der Fachmann konfrontiert sieht. Ein weiteres praxisrelevantes Problem ist die wünschenswerte Reduzierung der Heizzeit, d. h. eine Verringerung der Vulkanisationszeit. Geheizt werden Reifenformen üblicherweise mit Wasserdampf als Heizmedium, das in einen formeninnenseitig angeordneten Heizbalg eingeleitet wird, bzw. das durch entsprechenden Dampfkanäle in die Formsegmente eingeleitet wird. Seit langem ist es ein Ziel des Fachmanns, die Formsegmente möglichst schnell und kontrolliert auf Betriebstemperatur zu bringen, um hierdurch den gesamten Vulkanisationsprozess zeitlich zu optimieren.The However, removal of air from the tire vulcanizing mold is only one a series of problems that the skilled person faces sees. Another practice-relevant problem is the desirable one Reduction of heating time, d. H. a reduction in vulcanization time. Tire molds are usually heated with steam as the heating medium, which is arranged in a mold inside Bladder is initiated, or by corresponding steam channels in the Form segments is initiated. For a long time it has been a goal of the expert the shape segments as possible quickly and controlled to bring to operating temperature, thereby to optimize the entire vulcanization process in time.
Üblicherweise wurden bislang die Heizkanäle für den Wasserdampf in die Formsegmente gebohrt, gefräst oder durch Erodierverfahren in die Segmente eingebracht. Dies ist ein langwieriger und teurer Prozess, der sich nur bei entsprechenden Stückzahlen von mit der jeweiligen Form hergestellten Reifen wirtschaftlich rentiert.Usually So far, the heating channels have been for the Steam drilled into the mold segments, milled or by eroding introduced into the segments. This is a lengthy and expensive one Process that only works out with appropriate quantities of each Mold produced tires economically profitable.
Zudem weisen herkömmliche Formsegmente nur zwei oder drei Heizkanäle auf, die von Wasserdampf durchströmt werden, was dazu führt, dass sich das Formsegment zunächst ungleichmäßig erwärmt und es relativ lange dauert, bis eine gleichmäßige Erwärmung des Formsegments erreicht wird.moreover have conventional Mold segments only have two or three heating channels on top of that of water vapor flows through become what causes that the shape segment first heated unevenly and It takes a relatively long time to achieve a uniform heating of the molding segment becomes.
Für kleinere Stückzahlen, insbesondere im Prototypenbereich, sind derartige Formen jedoch zu teuer.For smaller ones Numbers, especially in the prototype area, however, such forms are too expensive.
Aufgabe der Erfindung ist es, eine Reifenvulkanisierform zu schaffen, die schnell und preiswert herzustellen ist und durch welche eine Reduzierung der Heizzeit eines Fahrzeugluftreifens ermöglicht wird.task The invention is to provide a Reifenvulkanisierform, the is fast and inexpensive to manufacture and by which a reduction of Heating time of a pneumatic vehicle tire is made possible.
Diese Aufgabe wird mit einer Reifenvulkanisierform gelöst, welche die Merkmale des Patentanspruchs 1 aufweist.This task is done with a tire vulkani solved sierform having the features of claim 1.
Erfindungsgemäß besteht eine Reifenvulkanisierform aus mehreren zu einer umfangsmäßig geschlossenen Form zusammenfügbaren Profilsegmenten, welche jeweils außenseitig aus einem Segmentgrundkörper und innenseitig jeweils aus einer profilierten Formfläche aus gesinterten Material aufweisen und mit sich ausgehend von dieser Formfläche durch das jeweilige Profilsegment nach außen erstreckenden Luftableitwegen versehen sind, wobei zumindest ein Teil der Luftableitwege wenigstens formflächenseitig aus einer Vielzahl miteinander in Verbindung stehender Mikrokanäle und Mikroporen besteht, wobei sich die Luftableitwege zumindest teilweise bis zur Rückenfläche des Profilsegments erstrecken, wobei sich die Reifenvulkanisierform erfindungsgemäß dadurch auszeichnet, dass zwischen Segmentgrundkörper und Formfläche eine Gitterstruktur angeordnet ist, durch welche ein Heizmedium leitbar ist.According to the invention a Reifenvulkanisierform from several to a circumferentially closed Form joinable Profile segments, each of which on the outside of a segment main body and each on the inside of a profiled molding surface having sintered material and starting from this form surface through the respective profile segment outwardly extending Luftableitwegen are provided, wherein at least part of the Luftableitwege at least the mold surface side consists of a multitude of interconnected microchannels and micropores, wherein the Luftableitwege at least partially up to the back surface of the Profile segments extend, wherein the Reifenvulkanisierform according to the invention thereby distinguishes that between segment base body and molding surface a Grid structure is arranged, through which a heating medium conductive is.
Die gestellte Aufgabe wird also auf überraschend einfache Art und Weise dadurch gelöst, dass eine dreidimensionale Gitterstruktur zwischen gesinterter Formfläche und Grundkörper angeordnet wird. Gemäß vorteilhaften Ausgestaltungen der Erfindung kann bei einem Verfahren zur Herstellung einer derartigen Form vorgesehen sein, dass das Gitter entweder als fertiges Teil auf den Grundkörper aufgelegt und anschließend die Formfläche auf das Gitter aufgesintert wird, oder dass alternativ die dreidimensionale Gitterstruktur durch ein Laser-Sinter-Verfahren direkt auf den Grundkörper aufgebracht bzw. dort erzeugt und anschließend die poröse Formoberfläche ebenfalls durch ein Laserschmelzverfahren auf der Gitterstruktur aufgebracht bzw. dort erzeugt wird.The Asked task is therefore surprising simple manner solved by having a three-dimensional Grid structure between sintered mold surface and base body arranged becomes. According to advantageous Embodiments of the invention may be used in a method of manufacture be provided in such a form that the grid either as a finished part on the basic body hung up and then the mold surface is sintered on the grid, or alternatively the three-dimensional Grid structure applied by a laser-sintering process directly on the body or generated there and then the porous one Mold surface also applied by a laser melting process on the lattice structure or generated there.
Bei diesem schichtweisen Aufbau des Formsegmentes ist es also nicht mehr nötig, Heizkanäle in einem späteren Schritt in das Segment einzubringen, sondern es entsteht sozusagen von allein beim schichtweisen Aufbau bzw. beim schichtweisen Erzeugen des gesamten Grundkörpers.at So this layered structure of the mold segment is not more necessary, heating channels in a later one Step into the segment, but it arises, so to speak by itself in the layered structure or in layered generating of the entire body.
Besonders vorteilhaft wird es sein, wenn sich die Gitterstruktur über 50 bis 95 % der Breite des Profilsegmentes erstreckt. Auf diese Weise entsteht ein Hohlraum innerhalb des Profilsegmentes, der gänzlich mit Wasserdampf geflutet werden kann, wodurch das Profilsegment innerhalb kürzester Zeit auf die gewünschte Betriebstemperatur gebracht werden kann. Dies führt zu einer erheblichen Reduzierung des Heizzyklusses.Especially it will be advantageous if the lattice structure exceeds 50 to 95% of the width of the profile segment extends. This way arises a cavity within the profile segment, which completely with Water vapor can be flooded, causing the profile segment inside short Time to the desired Operating temperature can be brought. This leads to a significant reduction of the heating cycle.
In einer praktischen Ausgestaltung der Erfindung kann vorgesehen sein, dass die dreidimensionale Gitterstruktur eine Höhe von 2 mm bis 20 mm und einzelne Gitterstäbe aufweist, welche eine Länge von 2 mm bis 10 mm und einen Durchmesser der Gitterstäbe von 0,5 mm bis 2 mm, sowie Abstände untereinander von 2mm bis 10 mm aufweisen.In a practical embodiment of the invention can be provided that the three-dimensional lattice structure has a height of 2 mm to 20 mm and single bars which has a length from 2 mm to 10 mm and a diameter of the bars of 0.5 mm to 2 mm, as well as distances between them from 2mm to 10mm.
In einer weiteren praktischen Ausgestaltung der Erfindung kann vorgesehen sein, dass die Mikrokanäle und Mikroporen einen Durchmesser von 30 bis 200 Mikrometer, vorzugsweise von 80 bis 200 Mikrometer aufweisen. Diese Porengröße hat sich als besonders vorteilhaft herausgestellt, da durch diese Luft schnell und sicher aus der Form abgeleitet werden kann, ohne dass Kautschuk in die Poren eindringt und die Luftkanäle hierdurch verstopft. Auch das Ausformen des Reifens lässt sich hierdurch positiv beeinflussen, ebenso das Aussehen der Lauffläche des Fahrzeugluftreifens selbst. Bei geschickter Einstellung der Porengröße lässt sich eine Oberfläche des Laufstreifens des Fahrzeugluftreifens erzeugen, welche dann den bekannten Lotuseffekt zeigt, d. h., dass Schmutz und andere unerwünschte Partikel nicht an der Oberfläche des Laufstreifens bzw. der Seitenwand des Fahrzeugluftreifens haften bleiben. Dies ist insbesondere im Neuzustand des Reifens von Vorteil, da er sich dann einem Kunden optisch besonders ansprechend präsentiert, da er tiefschwarz und glänzend erscheint. Aber auch, insbesondere wenn ein Formsegment der erfindungsgemäßen Reifenvulkanisationsform zur Schaffung der Seitenwandbereiche des Fahrzeugluftreifens eingesetzt wird, kann dies auch bei längerem Betrieb des Fahrzeugluftreifens positiv erscheinen, da sich durch den Lotuseffekt ein Selbstreinigungseffekt der Seitenwand einstellt und die Seitenwand stets sauber bleibt.In Another practical embodiment of the invention can be provided be that the microchannels and micropores have a diameter of 30 to 200 microns, preferably from 80 to 200 microns. This pore size has become proved to be particularly advantageous because of this air quickly and can be safely derived from the mold without using rubber penetrates into the pores and the air ducts thereby blocked. That too Forming the tire leaves This has a positive influence, as well as the appearance of the tread of the Pneumatic tire itself. With skillful adjustment of the pore size can be a surface of the tread of the pneumatic vehicle tire, which then shows the well-known lotus effect, d. h. that dirt and others undesirable Particles not on the surface adhere to the tread or the side wall of the pneumatic vehicle tire stay. This is particularly advantageous in the new state of the tire, since he presents himself visually appealing to a customer, because he is deep black and shiny appears. But also, especially if a mold segment of the tire vulcanization mold according to the invention used to create the sidewall portions of the pneumatic vehicle tire This can also be the case for a long time Operation of the pneumatic vehicle tire appear positive, as indicated by the Lotus effect sets a self-cleaning effect of the sidewall and the side wall always stays clean.
In praktischen Ausgestaltungen der Erfindung kann vorgesehen sein, dass für das Material der Formfläche sinterbarer Stahl oder sinterbares Aluminium verwendet wird; ebenso kann vorgesehen sein, dass für die dreidimensionale Gitterstruktur sinterbarer Stahl oder sinterbares Aluminium verwendet wird. Es ist ferner gemäß einer weiteren praktischen Ausgestaltung der Erfindung vorgesehen, für das Material der Formfläche ein Material zu verwenden, das unter der Handelsbezeichnung Metapor von der Firma International Mold Steel, Inc., 6796 Powerline Drive, Florence KY 41042 USA, erhältlich ist und bei dem es sich um ein besonderes Aluminium-Sintermaterial handelt.In Practical embodiments of the invention can be provided that for the material of the molding surface sinterable steel or sinterable aluminum is used; as well can be provided that for the three-dimensional lattice structure sinterable steel or sinterable Aluminum is used. It is also according to another practical embodiment provided for the invention, for the material of the molding surface to use a material sold under the trade name Metapor from International Mold Steel, Inc., 6796 Powerline Drive, Florence KY 41042 USA, available is and which is a special aluminum sintered material is.
Des Weiteren kann vorgesehen sein, dass das Profilsegment mit einem Vakuumanschluss versehen ist. Wird ein Vakuum angelegt, kann beim Zusammenfahren der Reifenvulkanisierform eingeschlossene Luft noch schneller abgeleitet werden.Of Furthermore, it can be provided that the profile segment with a Vacuum connection is provided. If a vacuum is applied, during the Collapse of tire vulcanization mold still trapped air be derived faster.
Gemäß eines erfindungsgemäßen Verfahrens wird das Profilsegment der erfindungsgemäßen Reifenvulkanisierform dadurch hergestellt, dass mittels eines an sich bekannten Laserschmelzverfahrens oder stereolithographischem Verfahrens, das auch unter der Bezeichnung Rapid Prototyping bekannt ist, auf dem Grundkörper die dreidimensionale Gitterstruktur aus einem sinterfähigen Pulvermaterial aufgebaut wird und dass anschließend auf die derart geschaffene dreidimensionale Gitterstruktur die mit Mikrokanäle und mit Mikroporen versehene Formfläche mittels Laserschmelzverfahren aus sinterfähigem Pulvermaterial aufgebaut wird.In accordance with a method according to the invention, the profile segment of the tire vulcanizing mold according to the invention is produced by using a laser melting method known per se Rens or stereolithographic process, which is also known under the name Rapid Prototyping, is constructed on the main body, the three-dimensional lattice structure of a sinterable powder material and then constructed on the thus created three-dimensional lattice structure provided with micro-channels and micro-pore molding surface by means of laser melting of sinterable powder material becomes.
Alternativ kann vorgesehen sein, dass die dreidimensionale Gitterstruktur als fertiges Bauteil auf den Grundkörper aufgelegt und mittels Laserschmelzverfahren auf der Gitterstruktur die Formfläche aufgebaut wird.alternative can be provided that the three-dimensional lattice structure as finished component on the body applied and by means of laser melting on the lattice structure the mold surface is built.
