Description
Technical field
The utility model relates to tyre vulcanized mould technical field more particularly to a kind of tyre vulcanized mould c-type air-casings.
Background technique
Molding tire is formed with the tire base that raw rubber state manufactures, needs the carry out high temperature and pressure by vulcanizer
Vulcanizing treatment.Vulcanizer generally includes the mold for having type chamber, and capsule portion is arranged at the mold cavity center, by outer when use
Portion loads and unloads device of tyre and tire base centered cover is set in capsule portion, to realize that it heats pressure effect.Since tire base is being placed in type chamber
When interior, initially there is gap between tire base outer wall and mold cavity wall.After tire base expanded by heating, how between excluding to be somebody's turn to do
Tire base molding effect is not interfered with while air at gap, to guarantee that tire base is smoothly expanded at cavity wall and final molding
As problem.
The structure of spring air-casing in the prior art, generally includes the sleeve-shaped valve casing as outer housing, coaxial in valve casing
It is arranged with columnar mandrel, is arranged with spring on mandrel.Unidirectional gear cooperation, and mandrel are constituted between mandrel bottom and valve casing one end
Then have the sealing mating surface that may make up unidirectional gear cooperation between top and the valve casing other end, above-mentioned two unidirectional gear cooperation
Limit direction arrangement reversely with each other.When practical application, arranged using what is opened up on mold through mold with communicate-type chamber and outside
Spring air-casing interference is inserted into gas vent by the gas vent of gas equipment, and makes sealing mating surface place end and the cavity wall of valve casing
Concordant setting.In sulfidation, tire base expanded by heating, tire base is gradually reduced with mold cavity wall gap.Due to making in spring
Under, the sealing mating surface of mandrel and valve casing is in the open state, thus in above-mentioned gap air along aforementioned seal mating surface
Gap and overflow, and excluded by external exhaust gas equipment.Until tire complete cure is completed, tire and mold cavity wall are continuously
Gap, the sealing mating surface of mandrel and valve casing is squeezed by tire at this time, so that the above-mentioned complete gluing, sealing of sealing mating surface.In tire
After vulcanization is completed and taken out, under elastic reaction, mandrel resets, and can be ready for new round vulcanisation operation.
Above-mentioned spring air-casing in actual use, there are the problem of have: firstly, spring air-casing is as pneumatic member, interior bullet
Spring Chang Yinwei rubber penetrate into or the factors such as elastic fatigue and lead to stuck and damage, and it is a large amount of due to often existing in a mold
The installation number of gas vent namely spring air-casing is extremely more, this results in the cost of integral replacing one by one high, and maintenance is installed also extremely
It is cumbersome to can't bear.It is easy to produce after being influenced by high temperature as the spring of metal material with high temperature secondly as sulfidation is inevitable
Raw elastic failure, causes spring service life to drastically reduce, these be all the generation to the practical effect of spring air-casing not
Benefit influences.
Therefore how to simplify air-casing structure, reduce the maintenance replacement frequency of air-casing, improve production efficiency, in recent years for this field
Carry out technical problem urgently to be resolved.

Die cavity connection；The fastening part and aforementioned bottom outlet close-fitting, and it is internally provided with venthole, which is in communication with the outside；It is described
Gas vent is connected to so that the gas in die cavity to be discharged with venthole.
Above-mentioned technical proposal can also be further perfect by following technical measures:
As a further improvement, the diameter of the gas vent is 0.03mm, the mesh number of gas vent is 281 mesh.
As a further improvement, the diameter of the gas vent is 0.03mm, the mesh number of gas vent is 342 mesh.
As a further improvement, the diameter of the gas vent is 0.03mm, the mesh number of gas vent is 191 mesh.
As a further improvement, the diameter of the gas vent is 0.05mm, the mesh number of gas vent is 124 mesh.
As a further improvement, the lower part of the fastening part is equipped with the taper guide part that diameter is gradually reduced.The guiding
The taper in portion is 4 °.
Due to using above technical scheme, the utility model is had following technical effect that
Structure that the air-casing of the utility model is nonelastic, therefore it is easy to be stuck and tired by excessive glue to effectively prevent spring air-casing
The problem of labor fails, greatly reduces the maintenance frequency, significantly improves production efficiency.And the air-casing structure letter of the utility model
Single, cost is relatively low, and when use is pressed into bottom outlet, very convenient.
