The metal die 10 of present embodiment possesses tyre surface mould portion 11, sidewall mould portion 12,13 and wire loop 14, and described tyre surface mould portion 11 is shaped tire face, and described sidewall mould portion 12,13 is shaped the sidewall portion of tire, the bead part of wire loop 14 beaded tyres.Although the diagram of omission, on the inner face of tyre surface mould portion 11, is provided with for form the convex skeleton portion of groove on the tyre surface of tire.In Fig. 1, although drawn at steam vent 16 of the inner face upper shed of tyre surface mould portion 11 and at a steam vent 16 of the inner face upper shed of sidewall mould portion 13, but in fact, the steam vent 16 in the inner face upper shed of tyre surface mould portion 11 or sidewall mould portion 12,13 is provided with a plurality of.
As shown in Figure 2, vent-peg 2 possesses tubular valve casing 3, valve rod 4 and afterburning element 5, and described tubular valve casing 3 has exhaust duct 21 in inside, described valve rod 4 inserts valve casing 3, become the spool that opens and closes exhaust duct 21, described afterburning element 5 to die cavity 15 reinforcings, makes exhaust duct 21 open valve rod 4.The end face 31a of the peristome 31 of valve casing 3 is towards die cavity 15.The end face 31a of peristome 31 and the end face 42a of head 42 are formed by plane respectively.On the bottom 32 of valve casing 3 that is configured in steam vent 16 inboards, be formed with the support portion 32b of through hole 32a and inward flange shape.
Valve rod 4 has columnar body portion 41 and head 42, and described columnar body portion 41 extends upward at the axle of valve casing 3, and described head 42 contacts by the inner face of the peristome 31 with valve casing 3, seals exhaust duct 21.Head 42 integrally arranges with main part 41, and makes the top of die cavity 15 those sides of main part 41 give prominence to and form diametrically.In the present embodiment, the head 42 of valve rod 4 forms the circular cone shape towards die cavity 15 hole enlargements, and the inner face of the peristome 31 of valve casing 3 forms with the conical surface towards die cavity 15 hole enlargements.
On the lower end of main part 41, form the limiter 43 larger than the diameter of through hole 32a, make thus valve rod 4 can from valve casing 3, not come off.Limiter 43 carries out strain by closed slits 44, thereby can pass through through hole 32a.Afterburning element 5 is around columned main part 41, between head 42 and support portion 32b, to valve rod 4 reinforcings.The vent-peg 2 of present embodiment is so-called spring venting (ス プ リ Application グ ベ Application ト), and it possesses the afterburning element 5 consisting of helical spring.But be not limited to this, such as also using disk spring or leaf spring etc. to form afterburning element 5.
In Fig. 2, exhaust duct 21 is open, and vent-peg 2 is in open mode.At vent-peg 2, during in open mode, the outer surface that is accompanied by tire approaches the action of forming face 1, and the air in die cavity 15 is discharged to the outside of metal die 10 via exhaust duct 21.Exhaust duct 21 is formed between the peristome 31 of valve casing 3 and the head 42 of valve rod 4, afterburning element 5 around the main part 41 and valve casing 3 of valve rod 4 between, between the main part 41 and through hole 32a of valve rod 4.When the outer surface of the tire contacting with forming face 1 is depressed valve rod 4, exhaust duct 21 is closed, and vent-peg 2 becomes closure state.
The aperture D16 of the steam vent 16 of circular hole is larger than the outer diameter D 3 that becomes valve casing 3 cylindraceous, between steam vent 16 and valve casing 3, forms the poor corresponding gap 6 of diameter with them.In the state of Fig. 2, bonding agent 7 is filled in gap 6, makes thus vent-peg 2 be fixed in forming face 1.Can manufacture this metal die 10 by following operation: forming face 1 is being arranged in the operation of steam vent 16, the aperture D16 that forms steam vent 16 is larger than the outer diameter D of valve casing 33, after steam vent 16 is installed in the operation of vent-pegs 2, in gap 6 between steam vent 16 and valve casing 3, fill bonding agent 7, vent-peg 2 is fixed in forming face 1.
Due to as mentioned above by after valve casing 3 matched in clearance are on steam vent 16, use bonding agent 7 that they are fixed, therefore can not occur due to the distortion of inserting the valve casing 3 that steam vent 16 causes, prevent as the action of the vent-peg 2 of spring venting badly, can suitably guarantee exhaust performance.In addition, by fill bonding agent 7 in gap 6, even aperture D16 slightly deviation do not have considerable influence yet, so D16 desired machining accuracy in aperture is so not high.Therefore, though by the looser method of machining accuracy the perforation that hand drill carries out as used, operate also no problem.
In addition, after vent-peg 2 being inserted through to the steam vent 16 that Drilling operation arranges, can omit steam vent 16 processing of reaming, in gap 6, fill bonding agent 7, thus fixing vent-peg 2.According to such operation, can reduce process time and processing cost, be useful.At the inner face of the steam vent 16 arranging by Drilling operation, for example having arithmetic average roughness Ra is surface roughness more than 0.8 μ m.Arithmetic average roughness Ra is by JIS B0601:2001 defined, and its evaluation method and step are according to the regulation of JIS B0633:2001.
In the process of vulcanization forming of repeatedly carrying out tire, because the pollution of blocking of waste materials or sulfiding gas causes a variety of causes such as situation of exhaust performance decline, and must replace vent-peg 2.Vent-peg 2 can unload from steam vent 16 by using bar-shaped work card tool pushing tow from the below of Fig. 2.Because the aperture D16 of steam vent 16 can't expand due to the installation of vent-peg 2, therefore do not hinder the new valve casing that inserts same size in the steam vent 16 after unloading valve casing 3, the replacement of vent-peg 2 is easy.
In addition, in the situation that valve casing is pressed into the forming face being formed by light metals such as aluminums, for example, under the heated condition when vulcanization forming (150～200 ℃), the compression stress producing due to thermal expansion difference acts on valve casing, can cause that thus the action of vent-peg is bad.On the other hand, in the metal die 10 of present embodiment, even if there is the variation in the gap 6 that causes due to such thermal expansion difference, because the bonding agent 7 more soft than valve casing 3 is filled in gap 6, filling part at this bonding agent 7 can reduce stress, therefore can prevent that the action of vent-peg 2 is bad.
On steam vent 16, be provided with the stage portion 17 of the bottom 32 of supporting valve casing 3.Stage portion 17 is to form by dwindling halfway the aperture of steam vent 16, and it has the step shape of the bottom surface that can block bottom 32.By such stage portion 17 is set, when vent-peg 2 is arranged on steam vent 16, can prevent coming off of the valve casing 3 of matched in clearance on steam vent 16, can determine the axial location of valve casing 3 simultaneously.
As long as bonding agent 7 can be filled in gap 6, vent-peg 2 is fixed in forming face 1, is not particularly limited, but improving aspect operability the property bonding agent of being preferably sick of.When vent-peg 2 is arranged on steam vent 16, from forming face 1 side hang down inject gap 6 lonely property bonding agent because capillarity diffuses in gap 6, by solidifying with contacting of metal, vent-peg 2 is fixed in forming face 1 simultaneously.The property bonding agent of being sick of is preferably low viscosity, for example, use Brookfield viscometer to measure, and the viscosity at 25 ℃ is preferably the bonding agent below 300mPas.
For example, under the non-heated condition before vulcanization forming (25 ℃), poor (D16-D3) of aperture D16 and outer diameter D 3 is preferably 0.04～0.1mm.Thus, when vent-peg 2 is arranged on steam vent 16, flow into the bonding agent 7 in gap 6, because capillarity easily circumferentially and is axially spreading, operability improves.In the present embodiment, steam vent 16 configures valve casing 3 with one heart relatively, and make gap 6 form ring-type, but be not limited thereto, can, by valve casing 3 is contacted with a part for the inner face of steam vent 16, thereby form, not the gap 6 of ring-type yet.
In addition, if above-mentioned poor (D16-D3) is below 0.1mm, easily guarantee to conduct to the heat of vent-peg 2 from the forming face 1 of metal die 10, can be conducive to prevention in the generation of the sulfuration inequality of the peripheral part of vent-peg 2.And then if this poor (D16-D3) is more than 0.04mm, the compression stress acting on valve casing 3 causing due to previously described thermal expansion difference is limited, therefore can be conducive to prevent that the action of vent-peg 2 is bad.
Owing to having, the general thermal conductivity such as resin of cementability is low, therefore preferably in bonding agent 7, sneaks into heat supply conduction and with material, improves thermal conductivity.Thus, can reduce the temperature difference between vent-peg 2 and its forming face 1 around, prevent that near sulfuration vent-peg 2 is uneven.In addition,, in the situation that half finished rubber flows into exhaust duct 21, heat conducts to rapidly this half finished rubber and promotes sulfuration can limit the growth of rubber burr.As heat supply conduction material, can enumerate metal that the thermal conductivities such as silver, copper, aluminium are high or the powder of carbon.In addition, can be also the high ceramic powder of thermal conductivity such as aluminium oxide, aluminium nitride, carborundum, graphite.
Use the manufacture method of the tire of described metal die 10 to comprise following operation: vulcanized tyre is not placed on the die cavity 15 of metal die 10, to this not vulcanized tyre implement heating pressurization and vulcanize.Tire carries out dilatating and deformable by being called as the expansion of the rubber bag of air bag, its outer surface contact forming face 1.In this process, the air between tire and forming face 1 is discharged to outside by the exhaust duct 21 of vent-peg 2.At this moment, can use attractor to attract the space in steam vent 16, to improve exhaust performance.
Above-mentioned tyre vulcanization metal die, except by vent-peg with respect to forming face install as described above fixing, other and common tyre vulcanization metal die are equal, can in the utility model, adopt shape, material or the mechanism etc. of any known.
The utility model is not subject to any restriction of above-mentioned embodiment, in the scope that does not depart from purport of the present utility model, can carry out various improvement and change.In the above-described embodiment, be the metal die structure that possesses tyre surface mould portion and pair of sidewall mould portion, but the utility model is not limited to this, be for example also applicable to cut apart for upper and lower two-part metal die structure at the central portion of tyre surface mould portion.
