Description

  

  



  Form zur Herstellung von Gummik¯rpern durch Vulkanisieren.



   Vorliegende Erfindung betrifft eine Form zur Herstellung von Gummikorpern. z. B. Autoreifen, durch Vulkanisieren.



   Für die   Herstellun,,    z. B. von zu   vulka-      nisierenden    Nutoreifen wurden bis jetzt Formen aus Gusseisen verwendet. Diese Formen hatten Nachteile, unter anderem wurden sie beim Vulkanisieren angegriffen usw.



   Zweck vorliegender Erfindung ist, diesen Nachteil zu beheben, und zwar wird dies   dadurch erreicht, dass    die aus Leichtmetall, z. B. einer   Aluminlumicgierung. besiehende    Form an der Innenwandung anodisch oxydiert ist. Vorteilhaft ist die Form vielteilig gemacht, z.   B.    kann sie für die Herstellung   von Autoreifen aus einer Vielzahl    von    Sen-    menten zusammengesetzt sein.



   In der beiliegenden Zeichnung ist als    Ausführungsbcispiel des Erfindungsgegen-    standes eine Form schematisch dargestellt die zur Herstellung von Autoreifen verwendbar ist, und zwar zeigt :    rit. 1    einen Querschnitt durch die Form nach der Linie 1-1 in   Fixe :   
Fig. 2 zeigt eine Draufsicht und
Fig. 3 eine Seitenansicht eines Formelementes.



   Die gezeichnete Form weist die beiden an   sicle    bekannten, durch gebrochene Linien   angedeutete Formkastenteile 1, 2 auf.    In diese Kastenteile 1, 2 sind Formelemente 3 aus einer Aluminiumlegierung eingelegt. Sie sind, um sicher in den Tcilen 1, 2 zu liegen, in Falze eingeschoben. Die Elemente 3 sind Segmente eines Ringes. Die Innenwände des Segmentes bilden zusammen die Innenwand der Form.   Die Flächen 4 sind genau geschlif-    fen. so   da3    zwischen benachbarten Elementen 3 keine freie Fuge bleibt, in welche Gummi   eintrcten    könnte. Die Innenwandung eines jeden Elementes 3 ist dem Profil des herzustellenden Reifens entsprechend geformt. Das Profil kann z.   B.    wie in Fig. 2 gezeigt ausgef hrt sein.



   Das Vulkanisieren etc. erfolgt in an sich   bekannterweise.    Es werden auch die nötigen Luftlöcher an den geeigneten Stellen angebracht. Damit die Segmente den chemischen  Einflüssen Widerstand leisten, sind sie anodisch   oxydiert. Es genügt dabei, wenn    die Innenwand oxydiert ist.



   Die ganze Form kann leicht zerlegt werden. Es können mit ihr komplizierte Reifenprofile leichter   als bis jetzt herbestellt    werden.



  



  Mold for the manufacture of rubber bodies by vulcanizing.



   The present invention relates to a mold for making rubber bodies. z. B. car tires, by vulcanizing.



   For the manufacture, e.g. For example, molds made of cast iron have been used up to now for nut tires to be vulcanized. These shapes had disadvantages, including being attacked when vulcanizing, etc.



   The purpose of the present invention is to remedy this disadvantage, and this is achieved in that the light metal, for. B. an aluminum alloy. The form is anodically oxidized on the inner wall. The shape is advantageously made in many parts, e.g. For example, it can be composed of a large number of elements for the manufacture of car tires.



   In the accompanying drawing, as an exemplary embodiment of the subject matter of the invention, a mold is shown schematically which can be used for the production of car tires, namely shows: rit.
Fig. 2 shows a plan view and
Fig. 3 is a side view of a molded element.



   The shape shown has the two molding box parts 1, 2 known from sicle and indicated by broken lines. In these box parts 1, 2 molded elements 3 made of an aluminum alloy are inserted. They are inserted into folds in order to lie securely in parts 1, 2. The elements 3 are segments of a ring. The inner walls of the segment together form the inner wall of the mold. The surfaces 4 are precisely ground. so that no free joint remains between adjacent elements 3, into which rubber could enter. The inner wall of each element 3 is shaped to match the profile of the tire to be produced. The profile can e.g. B. be executed as shown in FIG.



   The vulcanization etc. takes place in a known manner. The necessary air holes are also made in the appropriate places. In order for the segments to withstand chemical influences, they are anodically oxidized. It is sufficient if the inner wall is oxidized.



   The whole shape can be easily disassembled. It can be used to order complicated tire profiles more easily than before.
