Description

本発明は、タイヤ加硫金型とその製造方法に関するもので、特に、複数のプレートを積層して成る積層モールドとその製造方法に関する。   The present invention relates to a tire vulcanization mold and a manufacturing method thereof, and more particularly, to a lamination mold formed by laminating a plurality of plates and a manufacturing method thereof.

従来、タイヤを成形する際には、図３（ａ），（ｂ）に示すような、タイヤクラウン部の断面形状を有するクラウン部金型５１をホルダー５２に取付けたセグメント５３を複数個環状に連結した加硫金型５０を用い、成型された生タイヤの内側に圧力をかけて上記生タイヤ外表面を加熱された上記加硫金型５０の内壁に圧着させ、生ゴムを熱と圧力とで加硫する方法が行われている。
上記クラウン部金型５１は、通常、鋳造により実現するが、このような鋳造型は型製造に手間がかかるだけでなく、材料コストも高いことから、近年、低コスト・短納期化を目的として、鋳造型である上記クラウン部金型５１に代えて、図４に示すような、複数の薄板６１ａを積層してクラウン部の形状とした積層薄板６１をホルダー６２に保持したセグメント６３をタイヤ周方向に沿って複数個配列して環状のトレッドパターン形成部を構成した積層モールドが用いられるようになってきている。
上記薄板６１ａには、通常、アルミニウムやその合金が用いられるが、上記ホルダー６２の場合には、タイヤ加硫時のモールド嵌合において、アルミニウム製のセグメント同士では強度が不足することから、これを補強するため、その内径や内径部高さ、分割角度が組込むモールドのサイズに合わせて設計された鉄ホルダーが用いられている。 Conventionally, when a tire is molded, a plurality of segments 53 each having a crown portion mold 51 having a cross-sectional shape of a tire crown portion attached to a holder 52 as shown in FIGS. 3 (a) and 3 (b) are annularly formed. Using the connected vulcanization mold 50, pressure is applied to the inside of the molded green tire so that the outer surface of the green tire is pressed against the heated inner wall of the vulcanization mold 50, and the raw rubber is heated and pressurized. A method of vulcanization is performed.
The crown part mold 51 is usually realized by casting. However, such a casting mold not only takes time to manufacture the mold but also has a high material cost. Therefore, in recent years, for the purpose of low cost and short delivery time. 4. Instead of the crown mold 51, which is a casting mold, as shown in FIG. 4, a segment 63 in which a plurality of thin plates 61a are laminated to form a crown portion and a laminated thin plate 61 held in a holder 62 is held in a tire circumference. A multilayer mold in which a plurality of tread pattern forming portions are arranged by being arranged along the direction has been used.
For the thin plate 61a, aluminum or an alloy thereof is usually used. However, in the case of the holder 62, the aluminum segments lack strength in mold fitting during tire vulcanization. In order to reinforce, an iron holder designed according to the size of the mold into which the inner diameter, inner diameter height, and division angle are incorporated is used.

ところで、上記積層薄板６１を保持するホルダー６２は、上記のように、タイヤ種、すなわち、上記積層薄板６１の寸法に合わせて設計され製作されるが、上記ホルダー６２を鉄ホルダーとした場合には、素材の手配や加工が必要なことから、ホルダー６２の作製工期が上記積層薄板６１の作製工期よりも長くなってしまい、積層モールドの最大の利点である短納期製作のネックとなっていた。
また、モールドの製作コストについては、一品一様方式では、ホルダーの製作費用が１つのモールドに全て計上されるため、モールドの製作費が高くなってしまっていた。 By the way, the holder 62 for holding the laminated thin plate 61 is designed and manufactured according to the tire type, that is, the dimension of the laminated thin plate 61 as described above. However, when the holder 62 is an iron holder, Since the preparation and processing of the material are necessary, the manufacturing period of the holder 62 is longer than the manufacturing period of the laminated thin plate 61, which has become a bottleneck in the short delivery time, which is the greatest advantage of the laminated mold.
In addition, with regard to the mold manufacturing cost, in the single product uniform method, the manufacturing cost of the holder is all included in one mold, so the mold manufacturing cost is high.

本発明は、従来の問題点に鑑みてなされたもので、積層薄板を固定する鉄ホルダーを短期間で作製するとともに、積層モールドの製作費を低減することを目的とする。   The present invention has been made in view of the conventional problems, and an object thereof is to produce an iron holder for fixing a laminated thin plate in a short period of time and to reduce the production cost of the laminated mold.

本発明者らは、鋭意検討の結果、積層薄板よりも作製工期が長い鉄や特殊鋼などから成るホルダーを、複数種の積層モールドにて共用化することにより、上記課題を解決することができることを見出し本発明に到ったものである。
すなわち、本願の請求項１に記載の発明は、複数の薄板を積層して成る積層薄板をホルダーに固定して成る積層モールドであって、その内径と内径部高さとが複数種の積層薄板の内径と内径部高さよりも大きなホルダーと、上記ホルダーに固定される上記複数種の積層薄板から選択された積層薄板と、上記ホルダーと積層薄板との間に介挿される、上記ホルダーと積層薄板との径方向肉厚差に対応した厚みのスペーサとを備えたことを特徴とするものである。 As a result of intensive studies, the present inventors can solve the above problems by sharing a holder made of iron, special steel, or the like, which has a longer production period than the laminated thin plate, with a plurality of types of laminated molds. And the present invention has been reached.
That is, the invention described in claim 1 of the present application is a laminated mold in which a laminated thin plate formed by laminating a plurality of thin plates is fixed to a holder, and the inner diameter and the height of the inner diameter portion are a plurality of types of laminated thin plates. A holder larger than the inner diameter and the height of the inner diameter portion, a laminated thin plate selected from the plurality of laminated thin plates fixed to the holder, and the holder and the laminated thin plate interposed between the holder and the laminated thin plate, And a spacer having a thickness corresponding to the difference in thickness in the radial direction.

請求項２に記載の発明は、請求項１に記載の積層モールドにおいて、上記スペーサを、上記ホルダーと同じ強度を有する材料から成る板状部材、あるいは、複数枚の薄板を積層した積層体から構成したものである。
請求項３に記載の発明は、請求項１または請求項２に記載の積層モールドにおいて、上記ホルダーの分割角度を、モールド周方向の分割角度の規定範囲の最小値よりも小さいかまたは同等としたものである。
また、請求項４に記載の発明は、複数の薄板を積層して成る積層薄板を備えた積層モールドの製造方法であって、その内径と内径部高さとが複数種の積層薄板の内径と内径部高さよりも大きなホルダーを準備するとともに、上記ホルダーに、上記複数種の積層薄板から選択された積層薄板を固定する際に、上記ホルダーと積層薄板との径方向肉厚差に対応した厚みのスペーサを介挿させて上記積層薄板を固定するようにしたことを特徴とする。 A second aspect of the present invention is the laminated mold according to the first aspect, wherein the spacer is composed of a plate-like member made of a material having the same strength as the holder or a laminated body in which a plurality of thin plates are laminated. It is a thing.
Invention of Claim 3 WHEREIN: In the lamination mold of Claim 1 or Claim 2, the division | segmentation angle of the said holder is smaller than or equivalent to the minimum value of the prescription | regulation range of the division | segmentation angle of a mold circumferential direction. Is.
The invention according to claim 4 is a method for producing a laminated mold comprising a laminated thin plate formed by laminating a plurality of thin plates, and the inner diameter and inner diameter portion height thereof are the inner diameter and inner diameter of a plurality of laminated thin plates. A holder larger than the height of the part is prepared, and when the laminated thin plate selected from the plurality of types of laminated thin plates is fixed to the holder, the holder has a thickness corresponding to the radial thickness difference between the holder and the laminated thin plate. The laminated thin plate is fixed by inserting a spacer.

本発明によれば、積層モールドを製造する際に、その内径と内径部高さとが複数種の積層薄板の内径と内径部高さよりも大きなホルダーを準備して、これを上記複数種の積層薄板を固定する共通ホルダーとするとともに、積層薄板を固定する際に、上記ホルダーと積層薄板との径方向肉厚差に対応した厚みのスペーサを介挿させて固定するようにしたので、少ない種類の鉄ホルダーで、多くの種類の積層モールドを作製することができる。したがって、積層モールドを短期間で作製することができるとともに、一度使用したホルダーを回収し、次回以降作製時に再利用していくことで、モールドの製作費を大幅に低減することができる。   According to the present invention, when a laminated mold is manufactured, a holder is prepared in which the inner diameter and inner diameter part height are larger than the inner diameter and inner diameter part height of a plurality of types of laminated thin plates, and the holders are prepared. As a common holder for fixing the laminated thin plate, a spacer having a thickness corresponding to the radial thickness difference between the holder and the laminated thin plate is inserted and fixed. Many types of laminated molds can be made with an iron holder. Therefore, it is possible to produce a laminated mold in a short period of time, and it is possible to significantly reduce the mold production cost by collecting the holder once used and reusing it for the next and subsequent productions.

以下、本発明の最良の形態について、図面に基づき説明する。
図１は、本最良の形態に係る積層モールドの製造方法を示す図で、同図において、１は積層薄板を固定する鉄ホルダー、２Ａ，２Ｂは上記鉄ホルダー１にそれぞれ固定される互いに大きさ・形状の異なる積層薄板で、上記積層薄板２Ａ，２Ｂをタイヤ周方向に沿って複数個配列することにより、積層モールドを形成する。また、３Ａ，３Ｂはスペーサ部材、４は上記スペーサ部材３Ａ，３Ｂに挟持された積層薄板２Ａ，２Ｂを上記鉄ホルダー１に取付けるための取付部材で、本例では、上記積層薄板２Ａ，２Ｂをアルミニウムやその合金から成る複数の薄板から構成するとともに、上記スペーサ部材３Ａ，３Ｂとして、上記鉄ホルダー１と同等の強度を有する板状部材を用いている。
本発明においては、積層薄板を固定する鉄ホルダー１の形状を数種類に統一し、一つの鉄ホルダーを、積層薄板２Ａ，２Ｂなどの複数種類の積層薄板を固定する共通のホルダーとして使用する。すなわち、鉄ホルダー１の外部形状に関しては、上記積層モールドを加硫機に取付けるためのコンテナ形状により数種類に統一可能である。また、鉄ホルダー１の内部形状に関しては、薄板挿入部の内径α、周縁部の内径β、及び、内径部高さＨとを固定する。そして、積層薄板が円弧形状の薄板をタイヤ断面方向に積層して成る構造を活かし、１種類の鉄ホルダーに対して、薄板の径方向の肉厚を変化させることにより、複数種類のタイヤ外径を有する積層薄板を固定可能とし、更に、薄板の積層枚数により、複数種のタイヤ幅を有する積層薄板を固定可能としている。 Hereinafter, the best mode of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing a method for manufacturing a laminated mold according to the best mode. In FIG. 1, reference numeral 1 denotes an iron holder for fixing a laminated thin plate, and 2A and 2B denote sizes that are fixed to the iron holder 1, respectively. A laminated mold is formed by arranging a plurality of the laminated thin plates 2A and 2B along the tire circumferential direction with laminated thin plates having different shapes. 3A and 3B are spacer members, and 4 is an attachment member for attaching the laminated thin plates 2A and 2B sandwiched between the spacer members 3A and 3B to the iron holder 1. In this example, the laminated thin plates 2A and 2B are A plate-like member having a strength equivalent to that of the iron holder 1 is used as the spacer members 3A and 3B while being composed of a plurality of thin plates made of aluminum or an alloy thereof.
In the present invention, the shape of the iron holder 1 for fixing the laminated thin plates is unified into several types, and one iron holder is used as a common holder for fixing a plurality of types of laminated thin plates such as the laminated thin plates 2A and 2B. That is, the external shape of the iron holder 1 can be unified into several types depending on the container shape for attaching the laminated mold to the vulcanizer. Moreover, regarding the internal shape of the iron holder 1, the inner diameter α of the thin plate insertion part, the inner diameter β of the peripheral edge part, and the inner diameter part height H are fixed. And by utilizing the structure in which the laminated thin plates are formed by laminating arc-shaped thin plates in the tire cross-sectional direction, by changing the thickness in the radial direction of the thin plate for one type of iron holder, multiple types of tire outer diameters It is possible to fix a laminated thin plate having a plurality of tire widths depending on the number of laminated thin plates.

すなわち、本発明の鉄ホルダー１は、図１に示すように、ｒA，ｒBなどのタイヤ外径が周縁部の内径βと同程度であり、ｄA，ｄBなどの肉厚が周縁部の内径βと薄板挿入部の内径αとの差以上であり、かつ、ｗA，ｗBなどのタイヤ幅が内径部高さＨより小さい積層薄板２Ａ，２Ｂなどの複数種類の積層薄板を固定する共通ホルダーとして使用可能である。
具体的には、上記積層薄板２Ａの厚さ（上記積層薄板２Ａのタイヤ幅ｗA）とスペーサ部材３Ａと上記取付部材４との厚さの総計が鉄ホルダー１の内径部高さＨになるように上記スペーサ部材３Ａの厚さを設定すれば、上記積層薄板２Ａを上記鉄ホルダー１に固定することにより、タイヤ幅がｗA、タイヤ外径がｒAのタイヤを加硫する積層モールドのセグメント１０Ａを得ることができる。
また、上記積層薄板２Ａよりもタイヤ幅ｗBとタイヤ外径ｒBとが小さいタイヤを加硫する積層モールドに用いられる積層薄板２Ｂを上記鉄ホルダー１に固定する場合には、スペーサ部材３Ｂの径方向肉厚を、上記スペーサ部材３Ａの径方向肉厚ｄAに対して、積層薄板２Ａの肉厚ｄAと上記積層薄板２Ｂの肉厚ｄBとの差だけ大きくするとともに、上記スペーサ部材３Ｂの厚さを、上記積層薄板２Ｂのタイヤ幅ｗBとスペーサ部材３Ｂと上記取付部材４との厚さの総計が上記鉄ホルダー１の内径部高さＨになるように設定すれば、タイヤ幅がｗB、タイヤ外径がｒBのタイヤを加硫する積層モールドのセグメント１０Ｂを得ることができる。
また、上記スペーサ部材３Ａ，３Ｂは、上記鉄ホルダー１と同等の強度を有し、かつ、積層薄板２Ａ，２Ｂと同一形状であるので、タイヤ加硫時のモールド嵌合においても鉄ホルダー１の補強を必要としない。したがって、図２に示すように、上記鉄ホルダー１の分割角度θを、モールド周方向の分割角度の規定範囲の最小値よりも小さいか、または、同等としておけば、鉄ホルダー１を補強することなく、上記積層モールドを嵌合することができる。 That is, as shown in FIG. 1, the iron holder 1 of the present invention has a tire outer diameter such as r A and r B that is substantially the same as the inner diameter β of the peripheral portion, and a wall thickness such as d A and d B is the peripheral edge. A plurality of types of laminated thin plates such as laminated thin plates 2A and 2B that are equal to or greater than the difference between the inner diameter β of the portion and the inner diameter α of the thin plate insertion portion and the tire width such as w A and w B is smaller than the inner diameter height H. It can be used as a common holder for fixing.
Specifically, the total thickness of the laminated thin plate 2A (the tire width w A of the laminated thin plate 2A), the thickness of the spacer member 3A, and the mounting member 4 is the inner diameter height H of the iron holder 1. If the thickness of the spacer member 3A is set as described above, the laminated thin plate 2A is fixed to the iron holder 1 so that a laminated mold for vulcanizing a tire having a tire width w A and a tire outer diameter r A is obtained. A segment 10A can be obtained.
When the laminated thin plate 2B used for a laminated mold for vulcanizing a tire having a tire width w B and a tire outer diameter r B smaller than the laminated thin plate 2A is fixed to the iron holder 1, the spacer member 3B the radial thickness, the radial direction thickness d a of the spacer member 3A, so as to be larger by the difference between the thickness d B of the thickness d a and the laminate plate 2B of the stacked thin plates 2A, the spacer member If the thickness of 3B is set so that the total thickness of the tire width w B of the laminated thin plate 2B, the spacer member 3B, and the mounting member 4 becomes the height H of the inner diameter portion of the iron holder 1, A laminated mold segment 10B for vulcanizing a tire having a width w B and a tire outer diameter r B can be obtained.
Further, since the spacer members 3A and 3B have the same strength as the iron holder 1 and have the same shape as the laminated thin plates 2A and 2B, the iron holder 1 can be fitted even during mold fitting during tire vulcanization. Does not require reinforcement. Therefore, as shown in FIG. 2, the iron holder 1 is reinforced if the division angle θ of the iron holder 1 is smaller than or equal to the minimum value of the prescribed range of the division angle in the mold circumferential direction. And the laminated mold can be fitted.

このように、本最良の形態によれば、その内径αと内径部高さＨとが、固定する積層薄板２Ａ，２Ｂなどの複数種の積層薄板の内径と内径部高さよりも大きな鉄ホルダー１を作製し、上記複数種の積層薄板から選択された積層薄板２Ａまたは積層薄板２Ｂを上記鉄ホルダー１に固定する際には、上記複数種の積層薄板のそれぞれについて、上記積層薄板のタイヤ幅とスペーサ部材３Ａ，３Ｂなどのスペーサ部材の厚さと取付部材との厚さの総計が上記鉄ホルダー１の内径部高さＨになるようなスペーサ部材３Ａまたはスペーサ部材３Ｂを、上記鉄ホルダー１と積層薄板２Ａまたは積層薄板２Ｂとの間に介挿させて固定するようにすれば、上記鉄ホルダー１を、上記複数種の積層薄板を固定する共通ホルダーとして使用することができる。また、上記鉄ホルダー１は、加硫後に回収され、次回以降作製時に再利用することができる。したがって、少ない種類の鉄ホルダーで、多くの種類の積層モールドを作製することができ、モールドの製作費を大幅に低減することができる。   Thus, according to this best mode, the iron holder 1 whose inner diameter α and inner diameter portion height H are larger than the inner diameter and inner diameter portion height of a plurality of types of laminated thin plates such as the laminated thin plates 2A and 2B to be fixed. When the laminated thin plate 2A or the laminated thin plate 2B selected from the plurality of types of laminated thin plates is fixed to the iron holder 1, for each of the plurality of types of laminated thin plates, the tire width of the laminated thin plate and The spacer member 3A or the spacer member 3B is laminated with the iron holder 1 so that the total thickness of the spacer members such as the spacer members 3A and 3B and the thickness of the mounting member becomes the inner diameter height H of the iron holder 1. The iron holder 1 can be used as a common holder for fixing the plurality of types of laminated thin plates by interposing and fixing between the thin plates 2A or the laminated thin plates 2B. Further, the iron holder 1 is recovered after vulcanization and can be reused in the next and subsequent production. Therefore, many types of laminated molds can be manufactured with a small number of types of iron holders, and the manufacturing cost of the mold can be greatly reduced.

なお、上記最良の形態では、上記スペーサ部材３Ａ，３Ｂとして、上記鉄ホルダー１と同等の強度を有する板状部材を用いたが、上記スペーサ部材３Ａ，３Ｂとして、上記鉄ホルダー１と同等の強度を有する複数の薄板を積層した積層体を用いてもよい。
また、スペーサ部材３Ａ，３Ｂの厚さ（タイヤ幅方向肉厚）が厚い場合には、積層薄板２Ａ，２Ｂ側にアルミニウムやその合金から成る薄板をスペーサ部材の一部として使用し、鉄ホルダー１側に上記鉄ホルダー１と同等の強度を有する板状部材あるいは積層体を配置するようにしてもよい。 In the best mode, plate-like members having the same strength as the iron holder 1 are used as the spacer members 3A and 3B. However, the spacer members 3A and 3B have the same strength as the iron holder 1. You may use the laminated body which laminated | stacked the several thin plate which has.
When the spacer members 3A and 3B are thick (thickness in the tire width direction), a thin plate made of aluminum or an alloy thereof is used as a part of the spacer member on the laminated thin plate 2A or 2B side, and the iron holder 1 You may make it arrange | position the plate-shaped member or laminated body which has the intensity | strength equivalent to the said iron holder 1 in the side.

タイヤサイズがＰＳＲ ２０５／６５ Ｒ１５のタイヤを作製するため、以下のタイヤ外径及び内径幅を有する積層モールドを作製し、これを本方式にて共通鉄ホルダーに固定し、タイヤ加硫を実施した。
積層モールド ；タイヤ外径〜φ６４４（ｍｍ）
内径幅 〜１８７（ｍｍ）
共通鉄ホルダー ；内径 〜φ７１６（ｍｍ）
内径部高さ〜２６０（ｍｍ）
その結果、モールド嵌合部の変形もなく、従来の積層薄板の寸法に合わせたホルダーに固定した積層モールドを用いて加硫したタイヤと同等の性状のタイヤを加硫できた。
これにより、積層モールドの短納期製作を実現できるとともに、コストについても、ホルダーの共用化により約４０％程度の削減が可能であることが確認された。 In order to produce a tire having a tire size of PSR 205/65 R15, a laminated mold having the following tire outer diameter and inner diameter width was produced, and this was fixed to a common iron holder by this method, and tire vulcanization was performed. .
Laminated mold: Tire outer diameter ~ φ644 (mm)
Inner diameter 〜187 (mm)
Common iron holder; inner diameter ~ φ716 (mm)
Inner diameter height ~ 260 (mm)
As a result, it was possible to vulcanize a tire having the same properties as a tire vulcanized by using a laminated mold fixed to a holder matched to the dimensions of a conventional laminated thin plate without deformation of the mold fitting portion.
As a result, it was confirmed that the quick delivery of the laminated mold can be realized and the cost can be reduced by about 40% by sharing the holder.

このように、本発明によれば、少ない種類の鉄ホルダーで、多くの種類の積層モールドを作製することができるので、積層モールドを短期間で作製することができるとともに、モールドの製作費を大幅に低減することができる。   As described above, according to the present invention, since many types of laminated molds can be produced with a small number of types of iron holders, the laminated mold can be produced in a short period of time, and the production cost of the mold is greatly increased. Can be reduced.
