DEVICE AND METHOD FOR VULCANIZATION OF TIRES Russian patent published in 2022 - IPC B29C33/02 B29C33/10 B29C33/46 B29C35/02 

FIELD: car maintenance.

SUBSTANCE: When the mold (7) is closed, the dividing walls (15, 16) located on the outer circular side of the ring (14) of the container form a space (S) with the container (10) and hermetically block the communication between the inner and outer sides of the container (10), and the central ventilation duct (3h) communicating vertically through the central mechanism (3), a set of internal ventilation ducts (8h) of the shape formed in the shape (7) at intervals along the circumference in horizontal projection, the internal ventilation duct (10h) of the container formed in the components (11, 12 and 13) of the container and providing communication between the opposite surface (10a) and the space (S), and the space (S) is brought into communication and, using an air extraction machine (18) located outside the container (10) and connected to the lower end of the central ventilation duct (3h), unintended air (a) present inside the mold (7) is pumped out through the internal ventilation duct (8h) of the mold and the ventilation duct (10h) of the container, which are communicated.

EFFECT: creating a device and a method for vulcanizing tires, which, despite the simple configuration, effectively remove unintended air present inside the vulcanization mold at the vulcanization stage, while restraining variability in various parts of the tire.
