Abstract
A tire vulcanization mold can be configured to provide stable ventilation. For example, a tire molding surface has a ventilation groove having a rectangular shape in plan view. A blade has upper end, contact and communication sections. The upper end section thickness is smaller than a groove thickness. The contact section below the upper end section contacts both thickness-direction-facing side faces of the groove. The communication section communicates between a ventilation hole, and a small gap is formed between the groove and the upper end section. Alternatively, the blade has a groove section formed in at least one side face that faces in a blade thickness direction and extends between upper and lower blade ends to form a small gap between the groove and groove section. Air and gas pass through the gap and the communication section and vent to an exterior of the mold through the ventilation hole.
