Abstract
A mould without air holes for producing the surface of meridian tyre has a moulded pattern block which is composed of a linking sleeve and several sectorial splicing blocks arranged on the internal circumference of said linking sleeve and with pattern on their inner surfaces. It features that a small gap between adjacent sectorial blocks is used to replace air holes.
Description
Affiliated technical field
The present invention relates to the tire-mold technical field, especially a kind of meridian tyre surface non-air hole mould.
Background technology
Production process riding at present, that gently block radial-ply tyre generally has following steps: 1) will take turns fetus and be placed in the mold cavity that is heated to 180 ℃, the matched moulds pressurization; 2) pressurising in fetus is pressed to die cavity sidewall and tyre surface with fetus; 3) air between fetus and the mould tyre surface is discharged by steam vent, makes sizing material be full of die cavity easily; 4) pressurize is 8～10 minutes, the fetus typing, and the die sinking rear tyre is deviate from die cavity.In tire vulcanization process, because the tread contour complexity, the air between fetus and die cavity the phenomenon that place, decorative pattern dead angle sizing material is not fully filled will occur as can not smooth and easyly discharging, and causes waste product.Therefore, tire plant has the strict smooth and easy requirement of exhaust to mould.During mfg. moulding die, according to the exhaust requirements of tire, bore the rod radial air vent of some at the mould tyre surface, diameter is generally Φ 0.6～Φ 1.2mm.In sulfidation, the air between fetus and the mould tyre surface is by discharging in the steam vent, and sizing material also enters in the steam vent simultaneously, and staying diameter at surface of tyre after the demoulding is Φ 0.6～Φ 1.2mm, and length is the adhesive tape of 8～15mm.Utilize this mould to produce tire, Φ 0.6～Φ 1.2mm is arranged on the tyre surface of tire, length is the adhesive tape of 8～15mm, and just burr influences Appcarance guality of tyres on the one hand, wastes sizing material on the other hand.For improving Appcarance guality of tyres, need the artificial adhesive tape of pruning, increased the production cost of tire again.
Summary of the invention
In order to overcome the deficiency of existing riding, light clamp noon loose tool tool, the purpose of this invention is to provide a kind of meridian tyre surface non-air hole mould, this mould utilizes slit small between fan-shaped piece to replace the steam vent of traditional moulds, discharge the air between fetus and the mould tyre surface, because the slit is very little, so the finished tire face only leaves the vestige in fan-shaped piece slit and do not have adhesive tape.
The present invention solves technology and the case that its technical problem adopts: a kind of meridian tyre surface non-air hole mould, tread block with molded tread contour, tread block is made up of coupling sleeve and several fan-shaped pieces that are arranged on the distribution of coupling sleeve inner periphery, be provided with the slit between adjacent fan-shaped piece, fan-shaped piece inwall has the profile that is used for molded tread contour, fan-shaped piece two side outer rim is provided with venting cavity, venting cavity place corresponding to fan-shaped piece on the coupling sleeve is provided with venting cavity, and the venting cavity of coupling sleeve is provided with the venting channels that leads to the coupling sleeve outer wall.
For guaranteeing that in tire vulcanization process the exhaust gross area in slit is enough, described fan-shaped piece is that the position that has the exhaust characteristic point in arranging by the decorative pattern pitch is cut apart.
For guaranteeing that in tire vulcanization process the smooth and easy discharge of air energy between fetus and die cavity only leaves the vestige in piece slit again and do not have adhesive tape at the finished tire face simultaneously, the width in described slit is 0.01～0.02mm.
For guaranteeing that fan-shaped piece of unobstructed while of exhaust has enough intensity, described fan-shaped piece thickness L is 16～20mm.
The demand different according to the user, the material of described fan-shaped piece can be aluminium alloy, carbon element steel or stainless steel.
The invention has the beneficial effects as follows, the tread block of meridian tyre surface non-air hole mould of the present invention is made up of coupling sleeve and several fan-shaped pieces that are arranged on the distribution of coupling sleeve inner periphery, be provided with the slit between adjacent fan-shaped piece, utilize slit small between fan-shaped piece to replace the steam vent of traditional moulds, discharge the air between fetus and the mould tyre surface; Outer rim is provided with venting cavity in fan-shaped piece two side, venting cavity place corresponding to fan-shaped piece on the coupling sleeve also is provided with venting cavity, the venting channels that leads to the coupling sleeve outer wall is set on the venting cavity, make in the tire vulcanization process, exhaust is more smooth and easy, because the slit is very little, therefore the finished tire face only leaves the vestige in piece slit and does not have adhesive tape, tire outward appearance polishing is attractive in appearance, saves tyre stock, has reduced the tire cost of manufacture.

Among the figure, 1. tread block, 11. coupling sleeves, 111. venting cavities, 12. fan-shaped pieces, 121. venting cavities, 112. venting channels, 13. slits, 14. steam vents, 2. patrix sidewall, 3. counterdie sidewall.
The specific embodiment
As Fig. 1,2, meridian tyre surface non-air hole mould of the present invention shown in 3, tread block 1 with molded tread contour, patrix sidewall 2 and counterdie sidewall 3, tread block 1 is made up of coupling sleeve 11 and several fan-shaped pieces 12 that are arranged on the distribution of coupling sleeve 11 inner peripherys, fan-shaped piece 12 thickness L are 16～20mm, fan-shaped piece 12 is that the position that has the exhaust characteristic point in arranging by the decorative pattern pitch is cut apart, 12 of adjacent fan-shaped pieces are provided with slit 13, the width in slit 13 is 0.01～0.02mm, fan-shaped piece 12 inwalls have the profile that is used for molded tread contour, fan-shaped piece 12 two side outer rims are provided with venting cavity 121, venting cavity 121 places corresponding to fan-shaped piece 12 on the coupling sleeve 11 are provided with venting cavity 111, and the venting cavity 111 of coupling sleeve 11 is provided with the venting channels 112 that leads to coupling sleeve 11 outer walls.The demand different according to the user, the material of fan-shaped piece 12 can be aluminium alloy, carbon element steel or stainless steel.
In tire vulcanization process, the air between fetus and die cavity is arranged to venting cavity 121 by the slit 13 of 12 of fan-shaped pieces, by venting cavity 121 on the fan-shaped piece 12 and the venting cavity 111 on the coupling sleeve 11, discharges through venting channels 112.When manufacturing specification is the 185/60R14 radial-ply tyre, slit 13 width are 0.02mm, and length is 250mm, because of slit 13 is to cut apart by the position that has the exhaust characteristic point in the arrangement of decorative pattern pitch, therefore every pitch has a slit 13, and its exhaust gross area is 0.02 * 250mm=5mm
2
The tread block of the original radial-ply tyre mould shown in Fig. 4,5 is drilled with rod radial air vent 14 on the tread block, when manufacturing specification was the 185/60R14 radial-ply tyre, the quantity of the steam vent 14 of every pitch was 10, and the aperture is Φ 0.8mm, and the exhaust gross area is 0.4
2* π * 10=5mm
2
Therefore, utilize the steam vent on the traditional mould of slit replacement small between fan-shaped piece, can reach identical exhaust effect; And because the slit is very little, so the finished tire face only leaves the vestige in piece slit and do not have adhesive tape, tire outward appearance polishing is attractive in appearance, saves tyre stock, saves and prunes the adhesive tape work time cost, has reduced the tire cost of manufacture.
