- the invention relates to a method for producing mold segments of a
- a segmented Vulkanisierform for vehicle tires wherein the mold segments are assembled into a ring and wherein each mold segment has a cavity facing away from the Vulkanisierform segment back, with which the mold segment in a vehicle tire suitable device, preferably a segment shoe of the Vulkanisierform to arrange, and wherein each mold segment a mold side facing the cavity of the vulcanizing mold, which has the negative profile of the
- FaufstMakes includes and where the negative profile by means of a generative adversary.
- the tire vulcanization is carried out in heating presses, in which the green tire is inserted into a suitable Vulkanisierform and vulcanized under the action of heat and pressure.
- the mold segments shape and heat the finned strip of the green tire and shape its furring profile.
- the invention relates to any type of heating press
- Mold segments are traditionally produced by casting processes with subsequent machining or exclusively by machining.
- the invention has for its object to provide a process for the preparation of
- Component distortion can be produced and with which complex profile geometries can be realized.
- the invention is also based on the object to provide a corresponding mold segment and a vehicle tire available.
- this object is achieved according to the invention by selecting a carrier element serving as a segment back and applying the mold side together with the negative profile facing the cavity of the vulcanizing mold to this carrier element by means of the additive manufacturing process, so as to form a hybrid mold segment receives.
- Carrier element and mold side are cohesively connected to each other and inseparable from each other and thus form a hybrid piece with respect to their production and / or their materials.
- the mold side is applied cohesively to the carrier element element and thus forms the carrier element with the mold side of a hybrid mold segment, takes the
- a carrier element is a by conventional methods (eg. Urformen,
- Forming, cutting and cutting or joining produced semi-finished products such as a milled plate.
- the complete form side is made by the generative process. These include, for example, tread grooves, profile elements, specific features such as abrasion indicator, end surfaces and also arranged in the interior of the mold side structures, such as serving for bleeding structures. Therefore, this method is suitable both for the production of mold segments for trial / or
- mold side is to be understood as meaning the entire volume which is applied to the carrier element by means of one or a combination of several generative methods and which faces the cavity of the mold segment in the state of the mold segment mounted in the vulcanizing mold.
- the mold side contains the complete negative profile of the tread with all its configurations.
- At least the negative of the complete tire profile is generated generatively on the side of a conventionally produced carrier element facing the cavity of the vulcanization mold.
- the generatively generated material content remains permanently in the
- Segment body on the side facing away from the cavity of the vulcanization mold side is designed as a segment back.
- the carrier element is made of the same material or of a material which is similar in its physical properties to the material to be generatively produced. This ensures a secure material connection and a material compatibility. For example, any metals, metal alloys, as well as plastics and other materials that are suitable for the stated use in a tire mold and a corresponding processing are suitable.
- Tire mold segments which are manufactured according to the described manufacturing way of aluminum or aluminum alloys or steel or steel alloys, can be used due to the conventionally produced tire mold segments comparable physical product properties in the existing infrastructure while maintaining standardized processes.
- Titanium or a titanium alloy is likewise suitable as the building material, as a result of which good mechanical properties are obtained with a low weight of the component.
- the support element such that it has the shape of an approximately square plate or the shape of a contra-segment back or the final contour of a segment back and that subsequently on the
- Segment back to obtain the final contour of the segment back post-processed.
- the creation of a final contour of the segment back having support element is temporally and spatially independent and separable from the generative structure of the form side.
- the support plate can be brought before or after the generative application of the form side in the final contour as segment back, whereby the production of the mold segment is flexible.
- the surface of the carrier element lying opposite the segment back is guided flat and the mold side is brought onto the planar surface.
- a flat surface is according to the current state of the art for the Generative manufacturing processes of the powder bed based laser melting process necessary. This method is known, for example, under the name "Selective Laser Melting".
- the surface of the support element lying opposite the segment back is already made as a curved surface in accordance with the curved contour of the mold side, and the mold side is brought onto this curved surface.
- a curved surface can be printed by means of the so-called "build-up welding" as a generative manufacturing process.
- Form page is about the same size or larger than the volume of the segmented back located in the final contour.
- the carrier element such that it is composed of one or more components and / or of one or more materials.
- the support element made of steel may have an aluminum core for better thermal conductivity.
- Abrasion indicators, snowflake symbol and venting elements by means of generative manufacturing process applies.
- the form side can be converted into the final state by the generative manufacturing process and substitute any subsequent introduction of described design elements and corresponding processes and process steps required for this purpose. This results in time and cost advantages as well as reduced manufacturing complexity.
- the object is achieved in that it is produced according to one or more of the abovementioned method steps.
- the mold segment is characterized in that it consists of a carrier element and a mold side, wherein the mold side by means of a generative
- Carrier element is connected and form a hybrid mold segment with respect to their production and / or their materials.

- Fig. 1 shows schematically the essential components of a conventional
- Vulcanization mold or heating mold for a pneumatic vehicle tire for passenger cars The Vulkanisierform is located within a heating press, whose components are not shown.
- a heating press usually comprises a press top and a press bottom and has the corresponding mechanisms for positioning the tire to be vulcanized, for operating the components of the vulcanization mold, for introducing the heating media and for removing the finished vulcanized tire.

- at least one heating medium, in particular saturated steam (steam) is introduced to vulcanize the tire.
- the green tire (not shown) is heated from the outside via the segment shoes 7, the side wall shells 2, 4 and the bead rings 5, 15, so that this heater is commonly used as
- Exterior heating is called.
- a conventional bladder is not shown, which is arranged in a known manner and is pressurized with at least one heating medium under pressure to center the green tire in the form from the inside, wherein the bladder is brought into a mature Torusform. After the green tire is heated from the inside via the bladder, this type of heating is called interior heating.
