Therefore, the technical scheme disclosed by the invention can fully utilize the vulcanizing medium, reduce the waste, and realize three times of incremental pressurization on the capsule and pressurization by using the pressure pump only during the third pressurization by designing the structures and the position relations of the capsule shaping inflation passage, the first high-pressure inflation passage and the second high-pressure inflation passage so as to reduce the frequency and the number of the pumps, further realize the purposes of prolonging the service life of the pumps and reducing the cost; in addition, compared with the prior art, the pressure in the high-pressure tank can be greatly reduced, so that the safety is improved.

In addition, the structure, valve assembly arrangement and operation principle of the mold 10 according to the present invention are substantially the same as those of the mold of the patent application No. 2021200742863, and are not described herein.
The vulcanizing medium provided by the invention is provided with the high-pressure medium supply source 90 to provide the vulcanizing medium consisting of gas or air, so that the effect of providing a large amount of vulcanizing medium or supplementing the loss generated after the vulcanizing medium introduced last time is recycled for multiple times is realized.
In addition, the invention discloses a new energy tire vulcanization method, which comprises the following steps: firstly, a vulcanizing medium in a low-pressure tank or a high-pressure tank is introduced into the capsule through a capsule shaping inflation passage 21, so that the pressure in the capsule reaches a first preset value; then the vulcanizing medium in the high-pressure tank is introduced into the capsule through the first high-pressure inflation passage 22, so that the pressure in the capsule is continuously increased to a second preset value; then the pressure pump 231 in the second high-pressure inflation passage 23 introduces the vulcanizing medium in the high-pressure tank into the bladder, so that the pressure in the bladder is continuously increased to a third preset value, namely a pressure value required during tire vulcanization; when the tire vulcanization process is completed; firstly, discharging the vulcanizing medium part in the capsule to a high-pressure tank through a first high-pressure inflation passage 22, so that the pressure in the capsule is reduced to a fourth pressure value; then discharging the vulcanizing medium part in the capsule to a low-pressure tank through a capsule shaping inflation passage 21, and continuously reducing the pressure in the capsule to a fifth pressure value; finally, the pressure in the bladder is pumped to negative pressure by the pressure pump 231 to introduce the curing medium in the bladder to a low pressure tank or a high pressure tank to empty the curing medium in the bladder and unload the cured tire.
The first predetermined value, the second predetermined value and the third predetermined value described in the present invention have different values according to different tire specifications, production processes and the like, but the applicant has concluded, through trial and error, that the second predetermined value is 10 times or more of the first predetermined value and the third predetermined value is 1.25 times to 1.5 times of the second predetermined value, which are necessary values for preferable vulcanization. In addition, when the tire vulcanization process is completed, it is preferable that the fourth pressure value in the bladder is 1.5Mpa to 2Mpa, and the fifth pressure value in the bladder is 1Mpa to 1.5 Mpa. In addition, the invention also comprises a surge tank for fine-tuning the first predetermined value level within the capsule.

In addition, the vulcanization time and vulcanization temperature of the tire can be specifically set according to different tire specifications, production processes and the like, and are not described herein again.
The heating components can be electric heating, induction heating, sheathed heater, plate heater, box heater, belt heater, cast heater, etc. the invention has priority to electromagnetic heating mode.
In addition, the pressure control, the temperature control, the control of each on-off valve/proportional valve, and the like can be realized by an MCU control system or a PLC control system, and for those skilled in the field of mechanical automation, the above-mentioned controls are all known techniques and conventional techniques in the art, and are not innovative points of the present invention, so the details about the control part are not described herein.
In summary, the new energy tire vulcanization method disclosed by the invention mainly increases the pressure of the bladder three times in an incremental manner and only uses the pressure pump to increase the pressure during the third pressure increase, so that the purpose of reducing the cost is realized by reducing the use amount of the pump; in addition, compared with the prior art, the pressure in the high-pressure tank can be greatly reduced, so that the safety is improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that are within the spirit and principle of the present invention are intended to be included therein.
