Heating press and method for vulcanizing a vehicle tire in said heating press under vacuum

A heating press for a tire, the heating press comprising:

• a heating press upper part;
• a heating press lower part;
• a circular-ring-shaped hood upper part of a hood of the heating press upper part, the hood upper part having a container and mold parts of a segmented vulcanization mold in the container, wherein the heating press upper part is movable in an axial direction (P1) in such a way that the hood upper part is movable onto the heating press lower part to form a closed hood interior space;
• a press plate arranged above the container in the hood upper part and moveable in the axial direction (P1);
• at least one seal configured to establish vacuum-tightness between the heating press upper part and the heating press lower part;
• a pump configured to generate a vacuum in the closed hood interior space;
• the mold configured to be filled with a pressurized heating medium for a green tire and heated by internal heating;
• wherein the heating press upper part is movable together with the press plate in the axial direction (P1) in to a first stroke (H1) so that the heating press upper part sits on the heating press lower part and the hood interior space is closed vacuum tight via the at least one seal, while the vulcanizing mold is open in an air-permeable manner;
• and
• wherein the press plate is movable in the axial direction (P1) in a second stroke so that the mold parts move in a radial direction to completely close the vulcanizing mold under vacuum in the closed hood interior space.
