Example 2

The vulcanizing device provided by the embodiment is made on the basis of the scheme provided by the embodiment 1, and as shown in fig. 1-3 and fig. 5, the vulcanizing device is different from the vulcanizing device provided by the embodiment 1 in that: the lower surface of the first guide ring 63 is horizontally arranged.

Specifically, as shown in fig. 6, the air flow channel formed between the first guide ring 63 and the lower clamping ring 42 guides the heating medium to flow close to the lower side of the curing bladder 2, so that the tire curing temperature at the corresponding position outside the lower side of the curing bladder 2 reaches the requirement, and the quality of tire curing is ensured.

Example 3

The vulcanizing device provided by the embodiment is made on the basis of the scheme provided by the embodiment 1, and as shown in fig. 1-3 and fig. 6, the vulcanizing device is different from the vulcanizing device provided by the embodiment 1 in that: the first deflector ring 63 is linearly inclined toward the lower clamp ring 42.

Specifically, as shown in fig. 7, the first flow guide ring 63 is linearly and obliquely arranged towards the lower clamping ring 42, so that an airflow channel is formed between the first flow guide ring 63 and the lower clamping ring 42 to have a diffusion effect, the flow velocity and pressure of the heating medium passing through the airflow channel are increased, the heat exchange efficiency between the heating medium gas at a high flow velocity and the curing bladder 2 and between the heating medium gas and the heating assembly 5 is improved, and meanwhile, the guiding heating medium is guided to flow close to the lower side of the curing bladder 2, so that the internal temperature uniformity of the curing bladder 2 is improved.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
