Mehrteilige Formen mit einem zwischen zwei äußeren Formhälften angeordneten, aus Segmenten zusammengesetzten Stirnring zur Herstellung der Lauf mantel von Preßluftreifen sind bekannt. Das Schließen des Stirnringes, erfolgte dabei durch achsiales Zusammenziehen der einzelnen Bogenstücke, und zwar bevor die Form zwecks Vulkanisierens der eingeschlossenen Gummimasse erhitzt ίο werden konnte. Da die kalte Gummimasse sehr zähe ist, so mußten große Kräfte zum Schließen angewendet werden.Multi-part molds with one arranged between two outer mold halves Segmented end ring for the production of the barrel jacket of compressed air tires are known. The end ring was closed by axial contraction of the individual bend pieces, namely before the mold is heated for the purpose of vulcanizing the enclosed rubber compound ίο could be. Since the cold rubber mass is very tough, great forces had to be used Close to be applied.
Bei der den Gegenstand der vorliegenden Erfindung bildenden mehrteiligen und heizbaren Form mit zwischen den Formhälften angeordnetem, aus Segmenten zusammengesetztem Stirnring können die einzelnen Segmente des Stirnringes während der Vulkanisierung der Gummimasse radial gegen den Formkern-gepreßt werden.In the case of the multi-part and heatable ones forming the subject of the present invention The individual segments can form with an end ring composed of segments and arranged between the mold halves of the end ring during the vulcanization of the rubber mass radially against the Mold core-pressed.
Durch tiefes oder weniger tiefes EindringenThrough deep or less deep penetration
oder Einstellen der Ringsegmente in die eigentliche Form kann die Stärke des Gummis an der Lauffläche bei sonst gleichem Reifenprofil verschieden stark ausgeführt werden.Or setting the ring segments into their actual shape can change the strength of the rubber different thicknesses on the tread with otherwise the same tire profile.
Vor allem aber kann die Pressung der Gummimasse auch während der Vulkanisation bewirkt werden.Above all, however, the pressing of the rubber compound can also occur during vulcanization be effected.
Die Zeichnung veranschaulicht ein Aus-So führungsbeispiel des Erfindungsgegenstandes. Fig. 1 stellt denselben im Querschnitt dar, undThe drawing illustrates an exemplary embodiment of the subject matter of the invention. Fig. 1 shows the same in cross section, and
Fig. 2 zeigt einen Grundriß im verkleinerten Maßstabe. . .Fig. 2 shows a plan on a reduced scale. . .
α bezeichnet das Formenunterteil und a1 das Eormenoberteil, welche beide unmittelbar geheizt sind, b, bl und c, c1 sind die entsprechenden inneren Formteile, welche die Wulstränder mit den Enden der Gewebeeinlage erfassen und im yerschraubten Zustande festhalten sowie nach erfolgter Verschraubung die Form auf der Innenseite schließen. Der Formkern ist mit d bezeichnet. Das Ganze wird nach erfolgtem Zusammenbau in üblicher Weise durch ein Spannkreuz oder dergl. zusammengehalten und gepreßt. α denotes the lower part of the mold and a 1 the upper part of the mold, which are both directly heated, b, b l and c, c 1 are the corresponding inner mold parts, which grasp the bead edges with the ends of the fabric insert and hold them in the screwed state, as well as after the screw connection Close the mold on the inside. The mandrel is denoted by d . After assembly, the whole is held together and pressed in the usual way by a clamping cross or the like.
Auf der Außenseite der Form verbleibt die zur Aufnahme der Segmente e des Stirnringes dienende Ringspalte. In dieser sind die Segmente so geführt, daß etwa überschüssiger Gummi, sogenannter Austrieb, während des Anpressens der Segmente entweichen kann. Dieses Anpressen erfolgt durch radiales Verschieben der Segmente gegen den Formkern d mit Hilfe der Schrauben /, die in einem um die Form herumgelegten Ringe g angeordnet sind.The annular gap serving to accommodate the segments e of the end ring remains on the outside of the mold. In this the segments are guided in such a way that any excess rubber, so-called expulsion, can escape while the segments are being pressed on. This pressing takes place by radial displacement of the segments against the mold core d with the aid of the screws /, which are arranged in a ring g placed around the mold.
Mit dem Einstellen und Anpressen der Stirnringsegmente wird erst begonnen, nachdem zuvor durch Schließung der Form die Gummimasse nebst ihren Gewebeeinlagen fest um den Formkern gespannt und die Gummimasse durch Erhitzen der Form erweicht worden ist.The adjustment and pressing of the end ring segments is only started after beforehand, by closing the mold, the rubber compound and its fabric inlays are firmly clamped around the mold core and the rubber compound has been softened by heating the mold.
