Description

この発明は、タイヤ成形用金型にかかわり、更に詳しくはタイヤサイド部の周上に沿って形成した環状凸部にベントホール及びスピューの痕跡がなく、成形されたタイヤの外観を向上させることが出来るタイヤ成形用金型に関するものである。 The present invention relates to a tire molding die , and more specifically, the annular convex portion formed along the circumference of the tire side portion has no vent holes and traces of spew, and can improve the appearance of the molded tire. it relates to the tire mold that can be.

近年のタイヤにおいて、車輌とタイヤとの共振（空気抵抗の低減，ロードノイズ低減等）を避けることを目的としたり、またリムとの嵌合をチェックする目的のために、タイヤサイド部（例えば、ショルダー部とリムクッション部の成形面）の周上に所定の幅で，複数本の環状凸部を付ける方法が採用されている。   In recent tires, for the purpose of avoiding resonance between the vehicle and the tire (reduction of air resistance, reduction of road noise, etc.) or for checking the fitting with the rim, the tire side portion (for example, A method is adopted in which a plurality of annular convex portions are provided with a predetermined width on the circumference of the molding surface of the shoulder portion and the rim cushion portion.

このようなタイヤサイド部に環状凸部を付ける手段としては、タイヤ成形用の金型のサイドプレートに、タイヤサイド部に環状凸部を形成するための凹溝を切削加工しているのが一般的であり、またタイヤ加硫成形時に、金型と未加硫タイヤとの間に溜まったエアーを外部に排気させるために、前記凹溝内に多数のベントホールが加工されている（例えば、特許文献１参照）。   As a means for attaching an annular convex portion to such a tire side portion, it is common to cut a concave groove for forming the annular convex portion in the tire side portion on a side plate of a tire molding die. In order to exhaust the air accumulated between the mold and the unvulcanized tire to the outside during tire vulcanization molding, a large number of vent holes are processed in the groove (for example, Patent Document 1).

然しながら、多数のベントホールを備えた金型によりタイヤを加硫成形すると、多数のベントホールに加硫ゴムが流れ込み、製品タイヤのサイド部には多数の髭状の突起（スピュー）が発生する。   However, when a tire is vulcanized and molded with a mold having a large number of vent holes, the vulcanized rubber flows into the large number of vent holes, and a large number of hook-shaped protrusions (spew) are generated on the side portions of the product tire.

このため、タイヤ成形後のタイヤ仕上げ工程では、上記のスピューを切除する作業が不可欠となり、作業性及び生産性の向上を図ることが出来ないばかりか、切除したスピューの屑が多数散らばって作業環境を悪化させ、更に製品タイヤのサイド部の外観を向上させることが難しいと言う問題があった。
特開平２−８８３１０号公報 For this reason, in the tire finishing process after the molding of the tire, it is indispensable to cut out the above spew, and it is not only possible to improve workability and productivity, but also a lot of cut spew scraps scattered around the work environment. There is a problem that it is difficult to improve the appearance of the side portion of the product tire.
JP-A-2-88310

ここで、前記エアー排出管の連通穴は、傾斜面の最低部の略同一面上に位置するように埋設し、また前記エアー排出管の連通穴の端末部に面取り部を施すものである。   Here, the communication hole of the air discharge pipe is embedded so as to be located on substantially the same surface of the lowest part of the inclined surface, and a chamfered portion is provided at a terminal portion of the communication hole of the air discharge pipe.

また、上記のタイヤ成形用金型により、タイヤサイド部の周上に沿って形成した環状凸部にベントホール及びスピューの痕跡がないタイヤにすることが出来る。 Further, the tire molding die described above makes it possible to obtain a tire in which the annular convex portion formed along the circumference of the tire side portion has no vent holes and traces of spew .

この発明は、上記のように金型のサイドプレートに環状凹溝を形成すると共に、この環状凹溝の底面に、金型のサイドプレートに形成したベントホールに向かって、かつ金型の周方向に沿って傾斜面を設け、この傾斜面の最低部に前記ベントホールを形成し、このベントホールに、環状凹溝の周方向に向かって形成した連通穴と、この連通穴とベントホールとを接続する排気穴とを備えたエアー排出管を埋設したので、タイヤ加硫成形時に、タイヤのサイド部に形成された環状凸部に多数のスピューを発生させることなくエアー抜きを良好にして成形でき、またタイヤ仕上げ工程作業のスピュー除去作業を簡略化し、更に作業環境を改善することが出来る効果があり、またタイヤサイド部の周上に沿って形成した環状凸部にベントホール及びスピューの痕跡がなく、成形された製品タイヤの外観を向上させることが出来る効果がある。 In the present invention, the annular groove is formed in the mold side plate as described above , toward the vent hole formed in the mold side plate on the bottom surface of the annular groove , and in the circumferential direction of the mold. the inclined surfaces provided along, the vent holes are formed in the lowest portion of the inclined surface, this vent hole, a communicating hole formed toward the circumferential direction of the annular groove, and the communication hole and the vent hole Since the air discharge pipe with the exhaust hole to be connected is embedded, it can be molded with good air venting without generating many spews at the annular convex part formed on the side part of the tire at the time of tire vulcanization molding In addition, there is an effect of simplifying the spew removal work of the tire finishing process work and further improving the work environment, and a vent hole and an annular convex part formed along the circumference of the tire side part. No trace of Pew, there is can effectively improve the appearance of the product tire is molded.

以下、添付図面に基づきこの発明の実施の形態を説明する。 Embodiments of the present invention will be described below with reference to the accompanying drawings.

図１は、この発明を実施したタイヤ成形用金型の半断面図、図２は図１のＸ部の拡大断面図を示し、この金型１は、主としてタイヤＷのトレッド面Ｗａを成形するトレッドリング２と、タイヤＷのサイド部Ｗｂを成形する上下のサイドプレート３ａ，３ｂと、ビードリング４とで構成され、５はブラダーを示している。   FIG. 1 is a half sectional view of a tire molding die embodying the present invention, FIG. 2 is an enlarged sectional view of a portion X in FIG. 1, and this die 1 mainly molds a tread surface Wa of a tire W. It comprises a tread ring 2, upper and lower side plates 3 a and 3 b that form the side portion Wb of the tire W, and a bead ring 4, and 5 indicates a bladder.

この発明では、タイヤ加硫成形時に、タイヤサイド部Ｗｂの周上に所定の幅，高さの環状凸部６を形成するために、予めサイドプレート３ａ，３ｂの内周面上に環状凹溝７が一体的に形成されている。   In this invention, in order to form the annular convex portion 6 having a predetermined width and height on the circumference of the tire side portion Wb at the time of tire vulcanization molding, an annular concave groove is previously formed on the inner peripheral surfaces of the side plates 3a and 3b. 7 is integrally formed.

この環状凹溝７は周方向に微小の傾斜角度を設けた傾斜面７ａが形成してあり、この傾斜面７ａの最低部には、サイドプレート３ａまたは３ｂを貫通する段部８ａを備えたベントホール８が形成してある。このベントホール８には、図３〜図７に示すように、環状凹溝７の周方向に向かって形成した小径（例えば、直径0.6mm 前後) の連通穴９と、この連通穴９とベントホール８とを接続する小径（例えば、直径1.0mm 前後) の排気穴１０とを備えたエアー排出管１１が埋設してある。   The annular groove 7 is formed with an inclined surface 7a having a slight inclination angle in the circumferential direction, and a vent provided with a step portion 8a penetrating the side plate 3a or 3b at the lowest portion of the inclined surface 7a. A hole 8 is formed. As shown in FIGS. 3 to 7, the vent hole 8 includes a communication hole 9 having a small diameter (for example, about 0.6 mm in diameter) formed in the circumferential direction of the annular groove 7, and the communication hole 9 and the vent. An air discharge pipe 11 having an exhaust hole 10 having a small diameter (for example, a diameter of about 1.0 mm) for connecting to the hole 8 is embedded.

このエアー排出管１１は、前記ベントホール８の段部８ａに嵌合する径大頭部１１ａと筒状部１１ｂとから構成され、径大頭部１１ａの内部に環状凹溝７と平行、もしくは空気が抜けることが可能な位置に前記連通穴９を形成し、また筒状部１１ｂには、連通穴９の略中央でベントホール８とを接続する前記排気穴１０が形成されている。   The air discharge pipe 11 is composed of a large-diameter head portion 11a and a cylindrical portion 11b that fit into the step portion 8a of the vent hole 8, and is parallel to the annular groove 7 inside the large-diameter head portion 11a. The communication hole 9 is formed at a position where air can escape, and the exhaust hole 10 that connects the vent hole 8 at the approximate center of the communication hole 9 is formed in the cylindrical portion 11b.

前記エアー排出管１１の連通穴９は、傾斜面７ａの最低部の略同一面上に位置するように埋設し、またエアー排出管１１の連通穴９の端末部には面取り部１２が施されている。従って、このようなエアー排出管１１をサイドプレート３ａに埋設した金型を使用してタイヤＷを加硫成形すると、図８に示すように、タイヤＷのサイド部Ｗｂには、所定高さの環状凸部６が形成される。   The communication hole 9 of the air discharge pipe 11 is embedded so as to be positioned on substantially the same surface of the lowest part of the inclined surface 7a, and a chamfered portion 12 is provided at the end of the communication hole 9 of the air discharge pipe 11. ing. Therefore, when the tire W is vulcanized using a mold in which such an air discharge pipe 11 is embedded in the side plate 3a, the side portion Wb of the tire W has a predetermined height as shown in FIG. An annular convex portion 6 is formed.

そして、この環状凸部６が形成される際に、サイドプレート３ａ，３ｂとタイヤＷとの間のエアーＱは、環状凹溝７の浅い部分から深い部分に順次押し出され、更に環状凹溝７の最も深い位置（最も低い位置）に形成されたエアー排出管１１及びベントホール８から外部に排出されることになる。   When the annular convex portion 6 is formed, the air Q between the side plates 3a, 3b and the tire W is sequentially pushed from a shallow portion of the annular concave groove 7 to a deep portion, and further, the annular concave groove 7 is formed. The air is discharged to the outside through the air discharge pipe 11 and the vent hole 8 formed at the deepest position (the lowest position).

また、加硫成形時に溶融したゴム材料は、連通穴９内に若干流れ込むが、エアーＱの排出を阻害するよう程流れ込むことはなく、従ってタイヤ成形後の金型離型時には、連通穴９の端末部から破断されて環状凸部６内には、スピューの痕跡や突出したスピューの存在はない。   Further, the rubber material melted at the time of vulcanization molding slightly flows into the communication hole 9, but does not flow so as to hinder the discharge of the air Q. Therefore, when the mold is released after the tire molding, the communication hole 9 There are no traces of spews or protruding spews in the annular convex part 6 which is broken from the terminal part.

従って、上記のように構成した金型１によりタイヤＷを加硫成形すると、図８に示すように、タイヤＷのサイド部Ｗｂの周上には、タイヤＷのサイド部Ｗｂに沿って所定の高さで環状凸部６が形成されるが、その環状凸部６には、ベントホール及びスピューの痕跡がなく、成形された製品タイヤの外観を向上させることが出来る。   Accordingly, when the tire W is vulcanized by the mold 1 configured as described above, a predetermined length along the side portion Wb of the tire W is formed on the circumference of the side portion Wb of the tire W as shown in FIG. Although the annular convex part 6 is formed at a height, the annular convex part 6 has no trace of vent holes and spews, and the appearance of the molded product tire can be improved.

またタイヤ加硫成形時に、タイヤＷのサイド部Ｗｂに形成された環状凸部６に多数のスピューを発生させることなくエアー抜きを良好にして成形でき、またタイヤ仕上げ工程作業のスピュー除去作業を簡略化でき、作業環境を改善することが出来る   In addition, during tire vulcanization molding, the annular protrusion 6 formed on the side portion Wb of the tire W can be molded with good air venting without generating many spews, and the spew removal work of the tire finishing process is simplified. Can improve the working environment
