Further, the film is in ethylene propylene diene rubber, butyl rubber, chlorinated scoline, brombutyl
One or more rubber be made.
Further, the overwrap is one or more in twill, mylar, polyester cord, glassine paper
Combination.
Method present invention also offers gum cover is made using rubber flute profile transmission belt vulcanizing gum cover mould, including following step
Suddenly：
(1), with releasing agent brushing rubber flute profile transmission belt vulcanizing gum cover mould, outside rubber flute profile transmission belt vulcanizing gum cover mould
Week swathes film；
(2), seized with overwrap and wrap film；
(3), it is put into vulcanizing tank, covers cover plate；Relatively closed sky is formed between cover plate, base, film and overwrap
Chamber, vacuumizes, and is passed through interior external pressure vulcanization；
(4) after, vulcanization is finished, cooling and demolding cuts out sealing surface and required height on cutting machine.
The flute profile gum cover mould that conventional round modulus method is used cause tooth form to fill not full be primarily due to choke with resentment
Cause.Diameter with mould increases, and the pressure suffered by sizing material also increases near linear relation, in huge pressure and height
Under warm emollescence, sizing material deforms in initial vulcanization step forced flow, causes the gas between mould parietal tooth and sizing material to be sealed in
The inside, it is impossible to exclude, it is rough full to cause to fill tooth, particularly major diameter gum cover when it is particularly evident.
Compared with prior art, the present invention has advantages below：In conventional flute profile gum cover mould upper plate, increase certain
The anti-compression leg of the annular spread of height.After covering upper cover plate during vulcanization, anti-compression leg undertakes main pressure, and make cover plate, sizing material with
The mold wall for having flute profile forms certain cavity, is easy to the gas between mould tooth and sizing material to discharge, while using increasing during vulcanization
Plus the mode for vacuumizing, gas discharge is helped, reach and fill the full purpose of tooth.
