摘要： A heating press (1) for vulcanizing a vehicle tire under a vacuum,
comprising a heating press upper part (3) and a heating press lower part (6), wherein a container (2) having the mold parts (14, 16, 17, 18, 21) of a segmented vulcanizing mold and a cylindrical hood upper part (4) enclosing said container are arranged on the heating press upper part (3),
wherein the hood upper part (4) and the heating press upper part (3) can be moved independently of one another and relative to one another in the axial direction (P1),
wherein the cylindrical hood upper part (4) has a length (23) which is sufficient to form a closed hood interior space (12) with the heating press lower part (6) and heating press upper part (4) when the heating press upper part (3) is open,
wherein at least one respective vacuum-tight seal (5) is arranged on those surfaces at which the hood upper part (4) directly adjoins the heating press upper part (3) and—when the hood interior space (12) is closed—the heating press lower part (6), in order to make the closed hood interior space (12) sealable in a vacuum-tight manner,
wherein, in the course of a first stroke (H1), the hood upper part (4) can be moved independently of the heating press upper part (3) in the axial direction P1 in such a way,
wherein, in the course of a second stroke (H2), the heating press upper part (3) can be moved independently of the hood upper part (4) in the axial direction P1 in such a way that the vulcanizing mold can be completely closed under vacuum conditions in the interior space of the hood (12).-

摘要： A method is for producing a profile segment of a segmented casting-vulcanizing mold for vehicle tires, the molding area of which molds a segment of the tread profile of a tire to be vulcanized, including the steps: creating a rigid model segment having a casing-like tread surface; milling the profile positive of the tread into the casing-like tread surface of the model segment to obtain the master model; creating a flexible impression from the master model; creating a rigid plaster cast from the impression to form a casting core segment; casting all of the annular, placed-together casting core segments with an aluminium-magnesium alloy to obtain a vulcanizing mold, subsequently divided into profile segments. A plasma coating is applied to the tread of the model segment, into which the profile positive of the tread is subsequently milled to obtain the master model. Plasma coating gives the master model a defined roughness.
