Abstract
The utility model discloses a tire casing vulcanizing mold of a tire. The tire casing vulcanizing mold comprises a mold body, wherein the mold body is provided with vent holes; groove bodies are arranged on the cavity surface inside the mold body and the ends of the vent holes; each groove body is provided with a ventilation sheet. The ventilation sheets are machined by utilizing ventilating material, a certain amount of vent holes are formed in the mold, grooves of which the shapes are the same as those of the ventilation sheets are formed in the parts of the vent holes in the cavity surface of the mold, and the ventilation sheets are embedded in the grooves, thus, when the tire is vulcanized, excess gas can be exhausted from the ventilation sheets, but glue material cannot be lost. Therefore, glue knots cannot be produced on the tire without trimming again, and the aesthetic appearance of the tire surface is improved.
Description
Technical field
The utility model relates to a kind of tire production mould, is specifically related to a kind of cover tire production mould.
Background technology
Existing tyre vulcanized mould is shown in Fig. 1 ~ 3, its vulcanization as shown in Figure 4, during the tyre sulfuration of tire, there is certain gas between tire base 2 and mold 3 die cavities, capsule 1(or curing bag) in inflation or give during superheated water tire base 2 certain pressure, make tire base and die body reach identical completely, if the gas between tire base and die cavity can't be discharged at this moment, can cause the gas nest on carcass, cause the defective of outward appearance.For this reason, need to design steam vent or other forms of exhaust apparatus at mould, the gas during with the assurance tyre sulfuration between tire base and die cavity is discharged.Its exhaust mode is to beat the steam vent 4 of somes at mold 3, or adds the exhaust flange 5 of some, make between die cavity and outside to utilize hole to be communicated with, thus Exhaust Gas.
When gas was discharged, sizing material also can flow out along steam vent or exhaust flange, so that produce the glue hair worn in a bun or coil on the tire, the burr of namely often saying needs to prune behind tire building, and the glue hair worn in a bun or coil is removed, and is more loaded down with trivial details, and the tire good looking appearance degree that obtains is not enough.
The utility model content
The technical problems to be solved in the utility model produces the glue hair worn in a bun or coil when being the Outer Tyre sulfuration, and a kind of Outer Tyre sulfurizing mould that prevents that the glue hair worn in a bun or coil from producing is provided.
The technical solution of the utility model realizes in the following manner: a kind of Outer Tyre sulfurizing mould, comprise mold, and mold is provided with steam vent, on the described mold inner cavity surface, the termination of steam vent is provided with cell body, is provided with ventail in the cell body.
Described ventail is ellipse or rectangle.
Described ventail is the micropore metal ventail.
The utility model utilizes poromeric material to be processed into ventail, beat the steam vent of some at mould, steam vent is made the groove consistent with the ventail shape at the position of mold cavity face, ventail is bumped in the groove, like this, when tyre vulcanization, unnecessary gas can be discharged from ventail, and sizing material can not run off.So that can not produce the glue hair worn in a bun or coil on the cover tire, do not need again to prune, improved the aesthetics on cover tire surface.
Description of drawings
Fig. 1 is the structural representation of existing mold body.
Fig. 2 is the enlarged diagram in E zone among Fig. 1.
Fig. 3 is the enlarged diagram in F zone among Fig. 1.
Fig. 4 is that the existing mold body uses view.
Fig. 5 is ventail installment state schematic diagram in the utility model.
The specific embodiment
As shown in the figure, a kind of Outer Tyre sulfurizing mould comprises mold 3, and mold 3 is provided with steam vent 4, on described mold 3 inner cavity surface, the termination of steam vent 4 is provided with cell body, is provided with ventail 6 in the cell body.
Described ventail 6 is circle, ellipse or rectangle, and according to production process, ventail also can be other shape, such as pentagon, hexagon etc.
Described ventail 6 is the micropore metal ventail, and micropore metal is the ventilative metal material of a kind of high-quality, and inner being linked to each other by fine aperture consists of, and hole diameter is less than the molecular diameter of rubber, and the gas such as air can be permeated and pass smoothly.Ventail 6 adopts preferably material of gas permeability, can get final product through preventing in the gas that sizing material from leaking.
Claims (3)
1. an Outer Tyre sulfurizing mould comprises mold (3), and mold (3) is provided with steam vent (4), it is characterized in that: on described mold (3) inner cavity surface, the termination of steam vent (4) is provided with cell body, is provided with ventail (6) in the cell body.
2. Outer Tyre sulfurizing mould according to claim 1 is characterized in that: described ventail (6) is ellipse or rectangle.
