EXHAUST DEVICE AND TIRE MOLD

The present invention provides a venting device and a tire mold, which relates to a technical field of tire vulcanization process. A venting device provided by the present invention includes a core shaft and a sleeve sleeved over the core shaft, a venting passage is formed between the sleeve and the core shaft, the core shaft includes a shaft body, one end of the shaft body is connected to a shaft head, the other end of the shaft body is connected to a shaft end piece provided with a groove extending through the shaft end piece, and an end of the groove facing away from the shaft head is closed; the shaft end piece is used for axially stopping the shaft body, and the shaft end piece is further used for assembling the sleeve and the core shaft by contracting and springing back. The venting device provided in the present invention relieves the technical problems existed in the prior art that the closing stroke of the core shaft has low accuracy, the core shaft is less robust and susceptible to be broken, and venting passage blockage and rubber burr occurrence can be avoided.
