[0015] The following is combined with Figure 1 、 2 The specific implementation methods of the present utility model are further described.

[0016] The mica heating device of the vulcanizer includes a lower template 5 and an upper template 6. The upper template 6 is installed above the lower template 5 through connecting rods 7 at the four corners; a lower mold 8 is installed on the top of the lower template 5, and a lower heating plate 10 is welded to the upper part of the lower mold 8, and the lower heating plate 10 is connected to a lower thermocouple 12; an upper mold 9 is installed at the bottom of the upper template 6, and an upper heating plate 11 is welded to the lower part of the upper mold 9, and the upper heating plate 11 is connected to an upper thermocouple 13; the upper heating plate 11 and the lower heating plate 10 have the same structure, including mica 2, a nickel-chromium heating wire 3 is wound around the mica 2, the nickel-chromium heating wire 3 is connected to a power cord 1, and upper and lower cover plates 4 are provided on the mica 2 wrapped with the nickel-chromium heating wire 3; the upper heating plate 11 is connected to the upper thermocouple 13 through the power cord 1, and the lower heating plate 10 is connected to the lower thermocouple 12 through the power cord 1, and the lower thermocouple 12 and the upper thermocouple 13 are both connected to the rotorless vulcanizer.

[0017] By changing the structure of the mica sheet, the original ring-shaped mica is changed into a sheet-shaped mica wrapped with nickel-chromium heating wire 3. The number of nickel-chromium heating wire 3 windings is increased and the heat conduction surface is increased, and the heat loss is reduced, thereby extending the service life of the heating sheet.

[0018] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
