The opening of 1 gas vent 11 of mold offers the exhaust capillary 21 through exhaust flange ontology 2, exhaust capillary on exhaust flange ontology 2
21 shapes can be divided into any one in spherical, cylindrical, taper, multilateral shape and irregular shape, and exhaust capillary 21 is vented micro-
Hole 21 is provided at least one air inlet 211, and air inlet 211 is located at exhaust flange ontology 2 close to tire production mold 1 and tire rubber
It is glued touching side, 211 equivalent diameter of air inlet is not more than 100 μm, and equivalent diameter is to be calculated at the area of a circle by area of section is equivalent
Obtained by diameter.Exhaust capillary 21 on exhaust flange ontology 2 is set and passes through exhaust flange ontology for residual air in tire-mold 1
It 2 and is discharged by gas vent 11.Since 211 equivalent diameter of air inlet is not more than 100 μm, rubber can not pass through, by exhaust flange ontology 2
The aperture position for being mounted on gas vent 11 can effectively avoid generating feeler on tire while meeting exhaust and needing, air inlet
Preferably 0 μm -30 μm of 211 equivalent diameters, when 211 equivalent diameter of air inlet is not more than 30 μm, the case where meeting exhaust effect
Under, any feeler will not be generated, it should be noted that 21 inside diameter of exhaust capillary can remain unchanged and also arbitrarily change, and
And exhaust capillary 21 can be bending channel and be also possible to put-through channel.
Exhaust capillary 21 is provided at least one gas outlet 212, it is preferred that multiple gas outlets 212, tire-mold 1 is arranged
Interior residual air can be discharged after entering exhaust capillary 21 from the different gas outlets 212 of exhaust capillary 21, so as to make tire-mold 1
Interior residual air expulsion efficiency is higher.
As a kind of form that multiple exhaust capillaries 21 are arranged on exhaust flange ontology 2, exhaust flange ontology 2 is made as more
Porous materials, exhaust capillary 21 is arranged along different directions and the connection that intersects between exhaust capillary 21, makes the saturating of exhaust flange ontology 2
Gas is more preferable.
Exhaust flange ontology 2 is cylinder, and exhaust flange ontology 2 is inserted into the gas vent 11 of tire production mold 1.Tire production
Remaining air can enter gas vent 11 directly through exhaust flange ontology 2 and is discharged by gas vent 11 in mold 1.
Preferably, ventilation blind hole 22 is offered on exhaust flange ontology 2, ventilation blind hole 22 is cylinder shape groove, blind hole of ventilating
22 are overlapped with 2 center line of exhaust flange ontology, when exhaust flange ontology 2 is mounted on the opening of 1 gas vent 11 of tire production mold, ventilation
Blind hole 22 is located at exhaust flange ontology 2 and contacts side far from tire production mold 1 and rubber for tire, at this point, in tire production mold 1
Remaining air can enter gas vent close to the opening side of gas vent 11 and by ventilation blind hole 22 directly through exhaust flange ontology 2
11.The setting of ventilation blind hole 22 can be conducive to gas keeps the exhaust effect of exhaust flange ontology 2 more preferable by exhaust flange ontology 2.
Embodiment two

Shape be described in detail:
In conjunction with fig. 4 to fig. 6, exhaust flange ontology 2 includes sequentially connected closure part 23, interconnecting piece 24 and anti-delinking part 25,
By being gradually reduced far from 24 one end of interconnecting piece to close to 24 one end diameter of interconnecting piece, interconnecting piece 24 is both ends difference for middle closure part 23
The cylinder connecting with closure part 23 and anti-delinking part 25,25 top of anti-delinking part are divided into pyramidal structure.
Be provided with installation set 3 outside exhaust flange ontology 2,3 both ends open of installation set be it is horn-like, wrapped inside installation set 3
The second channel 32 positioned at the first passage 31 of upside and positioned at downside is included, 31 diameter of first passage is compared with 32 diameter of second channel
Greatly, 23 outer wall of closure part is bonded with 3 upper end opening inner wall of installation set, and 25 outer wall of anti-delinking part and 3 lower ending opening inner wall of installation set paste
It closes, 25 maximum gauge of anti-delinking part is not less than the minimum diameter of 3 lower ending opening of installation set, and is not more than 31 internal diameter of first passage, even
24 diameter of socket part is less than 32 internal diameter of first passage 31 and second channel.Installation set 3 is inserted into the opening of gas vent 11, wheel when use
Air in placenta 1 enters first passage 31 and second channel 32 by closure part 23, enters gas vent by 3 lower end of installation set
In 11.
3 lower part of installation set is separately equipped with seperated slot 33, and seperated slot 33 can make partially to be divided at least two parts under installation set 3,
And then exhaust flange ontology 2 is made to be easy to extract out out of installation set 3.When exhaust flange ontology 2 long-time service block when can directly by
Exhaust flange ontology 2 is extracted out out of installation set 3 carries out individually cleaning, has relative to mold 1 and exhaust flange ontology 2 is cleaned together
Easy to clean, time saving and energy saving advantage.
Embodiment three
The present embodiment is substantially the same with embodiment one, and only the structure of exhaust capillary 21 is different, below to the knot of gas vent 11
Structure is described in detail:
Referring to Fig. 7, exhaust capillary 21 is arranged at intervals with multiple, and each exhaust capillary 21 is parallel to each other, due to exhaust capillary 21
Being parallel to each other can make 2 production process of exhaust flange ontology easy, can reduce production cost, single by direction suitable for air
Gas vent 11.
Referring to Fig. 8, it is preferred that exhaust capillary 21 is covered with exhaust flange ontology 2, exhaust flange ontology 2 can be made to have good
