description A heating press (1) for vulcanizing a vehicle tire under a vacuum,having a heating press upper part (3) and a heating press lower part (6), wherein the heating press upper part (3) has a hood upper part (4) mounted thereon and a container (2), which contains mold parts (16, 18, 21) of a segmented vulcanizing mold, in this hood upper part (4), wherein the hood upper part (4) has a first circular ring (23), which is arranged fixedly on the heating press upper part (3), and a second circular ring (24), which adjoins this first circular ring coaxially in an axial direction and can be telescopically retracted and extended out over the first circular ring (23) in an axial direction P1,wherein vacuum-tight seals (5, 9) are arranged between the two circular rings (23, 24) and between the second circular ring (24) and the heating press lower part (6),wherein, after a first partial stroke (TH1), the hood upper part (3) can be moved in such a way that it rests on the heating press lower part (6) by way of the extended second circular ring (24), and the interior space of the hood (12) can be closed in a vacuum-tight manner by the seals (5, 9) although the vulcanizing mold is still open in an air-permeable manner andwherein a pump (10) and a vacuum tank (11), by means of which a vacuum can be generated in the interior space of the hood (12) after the first partial stroke (TH1), are provided,wherein, after a second partial stroke (TH2), the hood upper part (3) can be moved in such a way that the second circular ring (24) can be retracted out further over the first circular ring (23) and the vulcanizing mold can be completely closed under vacuum conditions in the interior space of the hood (12).
