The invention discloses a preheating device for a tire vulcanizing mold, and belongs to the technical field of tire vulcanizing equipment. The preheating device for the tire vulcanizing mold comprises an upper mold body and a lower mold body which are arranged in a steam room of the vulcanizing equipment. During mold closing, a tire cavity is formed between the upper mold body and the lower mold body; small holes which are communicated with the steam room and the tire cavity are formed on the upper mold body and the lower mold body, and a capsule device is arranged in the tire cavity; an external temperature medium channel which is communicated with the steam room is formed on the vulcanizing equipment; an internal temperature medium channel is formed on the capsule device; and a capsule expansion channel controlled by a valve is formed between the external temperature medium channel and the internal temperature medium channel. Therefore, the technical problem that the capsule is easily damaged during preheating the mold in the large or giant tire vulcanizing process is solved. The preheating device for the tire vulcanizing mold has reasonable structure, and is widely applied to the tire manufacturing industry.
Description
technical field [0001] The invention relates to the technical field of tire vulcanization equipment, in particular to a preheating device for a large or giant tire vulcanization mold. Background technique [0002] As we all know, after the tire shaping and vulcanizing machine is shut down, the mold must be preheated before the normal tire vulcanization. The purpose of preheating is mainly to ensure the quality of tire vulcanization. In the current preheating method on the market, the inside of the capsule is vacuum, and the external temperature medium is passed into the steam chamber of the vulcanizer to heat. According to the size of the mold, the preheating generally lasts for 3-8 hours after the external temperature medium reaches the process setting temperature. In this preheating method, the entire preheating process is due to the external temperature and steam pressure (usually the pressure of heavy tires is about 0.65MPa, and the pressure of giant tires is about 0.33...
