Description

Technical Field

[0002] Tire molds are molds used for vulcanization molding of various tires. Tire molds mainly include flexible molds, which include upper side plates, the inner surface edge of the upper side plates is closely attached to the mold pattern blocks, the outer side of the mold pattern blocks is provided with a middle mold sleeve assembly, the inner side of the middle mold sleeve assembly is closely attached to the lower side plates, the surface of the lower side plates is closely attached to the mold pattern blocks, and the center mechanism of the vulcanizer is provided at the center axis of the upper side plates and the lower side plates.

[0003] At present, the main heating methods for active molds in tire factories are mostly steamer type or hot plate type, both of which use high-temperature steam heat conduction. The hot plate type heats the upper and lower hot plates of the vulcanizer through high-temperature steam, and guides the steam to the upper and lower side plates of the mold through the upper cover and base of the mold sleeve. The steam enters the steam chamber of the middle mold sleeve, and the heat conduction slider conducts it to the tread block to achieve overall heating of the mold and vulcanization of the tire. Steam accounts for a high cost in the tire production process. The use of coal-fired steam boilers consumes a lot of energy, causes serious pollution, and has complex pipeline distribution, which is prone to leakage and causes safety accidents.
