Description
Technical field
This utility model relates to tire-mold field shaping technique, is specifically related to the tire-mold row of a kind of elbow type location
Device of air.
Background technology
In existing tire vulcanization process, in order to make the air in mold cavity be released out, so that rubber can
Being distributed evenly in mould, existing tire-mold all offers multiple steam vent on mold cavity.In sulfidation,
Owing to the aerofluxus of tread area is discharged by circular pore, these pores are usually located at mould inner tube of a tyre end face, and through
Wearing to mold outer surface, in the case of high pressure and Gao Re, unvulcanized rubber can be extruded into outside chamber, mould tire top；Work as sky
After gas is discharged from mould, rubber forms glue hair in being got into the steam vent being drilled with, and during the tire demoulding, these glue hair parts can
Can break in vent bore, when again carrying out tyre vulcanization, the discharge of type chamber air can be hindered, and then cause rubber not
Whole mold cavity can be completely filled with.In order to avoid this kind of situation, need to unload to be carried out from production line by tire-mold.
General washing and cleaning operation is to use drill bit to be got out by the rubber in each pore, the most time-consumingly, affects production efficiency；Vulcanizating
Tire on, major part glue hair stands on along with the demoulding on tire, for removing removing glue hair, and has to set special messenger and relevant device enters
Row is pruned, and not only affects the presentation quality of tire, and wastes sizing material, adds production cost.And announce in the market
The pore-free tire mould exhaust valve (CN102313057A) of improvement although structure is simple, the difference relying on thermal coefficient of expansion is full
Foot technical need, but technology acuracy and material etc. require height, once occur that blocking is difficult in maintenance.This utility model relates to one
Plant the tire-mold exhaust apparatus of elbow type location, and there is no such device in the market.
Summary of the invention
For forming the problem existing for glue hair processing method in steam vent in prior art, the one of this utility model offer
Plant the tire-mold exhaust apparatus of elbow type location, steam vent hose lining hair problem thoroughly can be solved, it is not necessary to again clean.
To achieve these goals, the technical solution adopted in the utility model is as follows: the tyre mould of a kind of elbow type location
Tool exhaust apparatus, including mandrel, sheath body and spring, described mandrel top is provided with block, is provided with elbow, described sheath body bottom mandrel
Intracavity bottom is provided with limiting stand, and shroud base is provided with groove and through hole, and described elbow passes through through hole at groove inner position, described bullet
Spring is enclosed within mandrel, and spring is positioned up and down by described limiting stand with block.
As preferred technical scheme, the upper shifting height of described block is less than or equal to the spacing on elbow summit with sheath body bottom surface
From.
As preferred technical scheme, the degree of depth of described groove is more than or equal to mandrel and the radius of elbow, the width of groove
Diameter more than elbow.
Described block is inverted cone, and block diameter is more than mandrel, and mandrel is stepped cylindrical body.
As preferred technical scheme, described block when being fully pressed in sheath body, the upper top of its upper surface and sheath body
Face is concordant.
The top inner face of described sheath body is taper seat, matches with the inverted cone periphery taper seat at mandrel top.
As preferred technical scheme, the inverted cone at described mandrel top exists with the inner face taper seat gap of sheath body
0.08mm-0.15mm, makes exhaust clearance reach optimum.
Described mandrel, block, sheath body the material coefficient of heat conduction close with the coefficient of heat conduction of mould.
Described sheath body be hollow structure and be embedded in mould steam vent in, the upper end face of sheath body and the inner surface of mould are put down
Together.
Described through-hole diameter is bigger than axle diameter.
This utility model have the beneficial effect that this exhaust apparatus is capable of the effect of die venting not binder removal；And
The exhaust apparatus processing method of this structure is simple and convenient, without complicated position limiting structure bottom mandrel, it is only necessary to bent by mandrel
Just the location moving up and down and rotating it is capable of, it is not necessary to by complicated technologies such as mandrel separations.Mandrel one-shot forming, and ladder
Column structure can carry out coarse positioning to spring.For meeting gap requirement, after adjusting gap, reprocessing elbow technique ensure that
Gap is unlikely to the least, and makes air to be completely exhausted out.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described for the ease of it will be appreciated by those skilled in the art that.
A kind of tire-mold exhaust apparatus of elbow type location, including mandrel 2, sheath body 4, spring 3,
Described mandrel 2 top is provided with block 1, is provided with elbow 5 bottom mandrel 2, and described sheath body 4 intracavity bottom is provided with limiting stand 7, sheath body 4
Bottom is provided with groove 8 and through hole 6, and described elbow 5 is enclosed within mandrel 2 at groove 8 inner position, described spring 3 by through hole 6, institute
State limiting stand 7 with block 1, spring about 3 to be positioned.
As preferred technical scheme, the upper shifting height of described block 1 less than or equal to elbow 5 summit and sheath body 4 bottom surface it
Spacing, prevents mandrel 2 from moving down and causes elbow 5 to depart from groove 8, is allowed to limit mandrel 2 and rotates.
As preferred technical scheme, the deep of described groove 8 is more than or equal to mandrel 2 and the radius of elbow 5, the width of groove 8
Degree is more than the radius of elbow 5, and described elbow 5 will be unable to depart from groove 8.
Described block 1 is inverted cone, and block 1 diameter is more than mandrel 2, and mandrel 2 is stepped cylindrical body.
As preferred technical scheme, described block 1 is when being fully pressed in sheath body 4, and its upper surface is upper with sheath body 4
Either flush.
The top inner face of described sheath body 4 is taper seat, matches with the inverted cone periphery taper seat at mandrel 2 top.
As preferred technical scheme, the inverted cone at described mandrel 2 top and the inner face taper seat gap of sheath body 4 exist
0.08mm-0.15mm, makes exhaust clearance reach optimum.
Described mandrel 2, block 1, sheath body 4 the material coefficient of heat conduction close with the coefficient of heat conduction of mould.
