Zusammenfassung:	Mold (22) for vulcanizing a tire comprises a lining (2) for molding the tread of this tire and a mobile valve (1) intended to vent the mold (22). The valve is of a single piece and is guided in a guide part (200) belonging to the lining and in abutment on each side of this guide part to limit the movement of the valve in the lining. This valve and this guide part are made from the same material. The mobile valve thus produced is of one piece and non-removable from the guide part, and is therefore quicker and more accurate. It is held in the guide part by two abutments and, because it is made from the same material as the guide part, these can be produced at the same time. The mold in general comprises several valves to remove the air trapped during the molding of the tire.
