Description

本発明は、ゴム加硫用モールドに関し、さらに詳しくは、表示プレートの着脱操作を容易としながら表示プレートを確実に固定できるようにしたゴム加硫用モールドに関するものである。 The present invention relates to a rubber vulcanization mold, and more particularly, to a rubber vulcanization mold that can securely fix a display plate while facilitating the attaching and detaching operation of the display plate.

同一サイズで同一構造の空気入りタイヤは同一の加硫用モールドにより成形されるが、空気入りタイヤには、後日その製造履歴を追跡することができるように、製造時期や製造場所などを文字や記号などの識別マークとしてサイド面に付すようになっている。この識別マークは、変更に応じて取り替えるため、その刻印には加硫用モールドとは独立の刻印用の表示プレートを用意し、これを加硫用モールドの成形面に着脱自在に取り付けて付すようになっている。   Pneumatic tires of the same size and structure are molded with the same vulcanization mold, but for pneumatic tires, the production time and production location etc. should be written and written so that the production history can be traced later. It is attached to the side surface as an identification mark such as a symbol. In order to replace this identification mark in accordance with the change, a marking display plate independent from the vulcanizing mold is prepared for the marking, and this is attached to the molding surface of the vulcanizing mold in a detachable manner. It has become.

従来、この表示プレートのモールドに対する取り付けはビス止めによって行なわれていたが、その着脱に要する時間を短縮するため、接着剤を使う方法が提案された。しかし、この方法では、接着剤の塗布のために別工程が必要であり、表示プレートの接着性が不安定などの問題があって、必ずしも生産性の向上に寄与するものではなかった。   Conventionally, the display plate is attached to the mold by screws, but a method using an adhesive has been proposed in order to shorten the time required for the attachment and detachment. However, this method requires a separate process for applying the adhesive, and has problems such as unstable adhesion of the display plate, and does not necessarily contribute to improvement of productivity.

また、別の方法として表示プレートを磁力によりモールドに吸着固定させる提案がなされている（特許文献１参照）。しかし、磁力による吸着固定だけでは、タイヤ側の圧力などにより表示プレートが位置ずれなどを起こすことがあり、その固定に確実性が欠けていた。このように、従来のモールドでは表示プレートの装着を簡単にしながら確実に固定できるようにするには未だ課題があった。
特開昭５９−５５７３０号公報 As another method, a proposal has been made to attract and fix the display plate to the mold by magnetic force (see Patent Document 1). However, only by the adsorption fixation by magnetic force, the display plate may be displaced due to the pressure on the tire side, and the fixation is lacking in certainty. As described above, the conventional mold still has a problem in that it can be securely fixed while simplifying the mounting of the display plate.
JP 59-55730 A

本発明の目的は、表示プレートの取付け操作を簡単にしながら表示プレートを確実に固定できるようにしたゴム加硫用モールドを提供することにある。本発明の他の目的は、特にタイヤ成形用として、表示プレートの取付け操作性を簡単にしながら表示プレートを確実に固定できるタイヤ加硫成形モールドを提供することにある。   An object of the present invention is to provide a rubber vulcanization mold capable of securely fixing a display plate while simplifying an operation of attaching the display plate. Another object of the present invention is to provide a tire vulcanization molding mold that can securely fix the display plate while simplifying the mounting operability of the display plate, particularly for tire molding.

上記目的を達成するため本発明のゴム加硫用モールドは、被成形ゴムの表面に文字や模様などの識別マークを付形する表示プレートをモールド側に設けた嵌合凹部に着脱可能に取り付けたゴム加硫用モールドにおいて、前記ゴム加硫用モールドおよび表示プレートの少なくとも一方に相互に吸着させる磁力を持たせるとともに、前記表示プレートの端部を前記モールドに対して係合手段により着脱自在に係止可能としたことを特徴とするものである。   To achieve the above object, the rubber vulcanization mold of the present invention is detachably attached to a fitting recess provided on the mold side with a display plate for forming identification marks such as letters and patterns on the surface of the rubber to be molded. In the rubber vulcanization mold, at least one of the rubber vulcanization mold and the display plate has a magnetic force to be attracted to each other, and the end of the display plate is detachably engaged with the mold by an engaging means. It is characterized by being able to be stopped.

本発明によれば、モールドに設けた嵌合凹部に対して着脱自在とした表示プレートを磁力により吸着させると共に、係合手段によりモールドに係止可能としたので、表示プレートの着脱が容易であると共に、外力に対して横ずれなど生ずることはなく確実な固定が可能となる。   According to the present invention, the display plate that is detachably attached to the fitting recess provided in the mold is attracted by magnetic force and can be locked to the mold by the engaging means, so that the display plate can be easily attached and detached. At the same time, there is no occurrence of a lateral shift or the like with respect to the external force, and the fixing can be performed reliably.

以下、本発明のゴム加硫用モールドを図に示した実施形態に基づいて説明する。図１に示す第１の実施形態では、細長形状をした薄板状の表示プレート２が、着脱自在にモールド１に設けられた嵌合凹部６に嵌め込まれて取り付けられるようになっている。加硫成形されるゴムの表面には、この表示プレート２によって製造時期や場所などを示す識別マーク等が付されることになる。   Hereinafter, the rubber vulcanization mold of the present invention will be described based on the embodiments shown in the drawings. In the first embodiment shown in FIG. 1, an elongated thin plate-like display plate 2 is fitted into a fitting recess 6 provided in the mold 1 in a detachable manner. On the surface of the rubber to be vulcanized and molded, an identification mark or the like indicating the production time or location is attached by the display plate 2.

この表示プレート２は、鉄などの磁石に吸着する材質で形成され、一端側に係合孔７を有している。嵌合凹部６の底面の一端側にはフック５が突出して設けられており、他端側には磁石３が埋め込まれている。磁石３は表示プレート２の底面に設けてもよく、表示プレート２全体を磁石にして磁力を持たせるようにしてもよい。   The display plate 2 is formed of a material that is attracted to a magnet such as iron, and has an engagement hole 7 on one end side. A hook 5 protrudes from one end of the bottom surface of the fitting recess 6 and a magnet 3 is embedded at the other end. The magnet 3 may be provided on the bottom surface of the display plate 2, or the entire display plate 2 may be magnetized to have a magnetic force.

表示プレート２は、係合孔７にフック５を貫通させて係合させてから嵌合凹部６に嵌め込むだけでモールド１に取り付けることができる。   The display plate 2 can be attached to the mold 1 simply by fitting the display plate 2 into the engagement recess 6 after the hook 5 is passed through the engagement hole 7 and engaged therewith.

取付けが完了した状態は、図２にその縦断面を示すように、表示プレート２はフック５による係止と共に、磁石３による吸着でモールド１に確実に固定されるので、ゴムを加硫する際に、ゴム側から圧力等を受けてもずれることがない。また、加硫後に加硫されたゴムに付着して、共に脱型されて紛失してしまうこともない。   When the mounting is completed, as shown in the longitudinal section of FIG. 2, the display plate 2 is securely fixed to the mold 1 by being attracted by the magnet 3 together with being locked by the hook 5, so that the rubber is vulcanized. Furthermore, even if it receives pressure from the rubber side, it does not deviate. Moreover, it adheres to the vulcanized rubber after vulcanization and is not demolded and lost.

表示プレート２の取り外しは、嵌合凹部６に埋め込まれた磁石３よりも磁力の強い磁石で表示プレート２を吸着して引き上げつつ、フック５の係止を外すだけで容易に行なうことができる。この実施形態では、フック５と磁石３の位置が離れているので、特に表示プレート２の着脱が容易で、モールド１への固定も安定する。   The display plate 2 can be easily removed simply by releasing the hook 5 while adsorbing and pulling up the display plate 2 with a magnet having a stronger magnetic force than the magnet 3 embedded in the fitting recess 6. In this embodiment, since the hook 5 and the magnet 3 are separated from each other, the display plate 2 is particularly easy to attach and detach, and the fixation to the mold 1 is also stable.

なお、表示プレート２がアルミニウムや樹脂などの磁石３に吸着しない材質で形成される場合は、嵌合凹部６に嵌め込んだ際に磁石３と当接する部分に鉄板などの磁石に吸着する磁性吸着部４を表示プレート２に設ければよい。   When the display plate 2 is formed of a material that is not attracted to the magnet 3 such as aluminum or resin, the magnetic adsorption that is attracted to the magnet such as an iron plate at the portion that comes into contact with the magnet 3 when the display plate 2 is fitted into the fitting recess 6. The part 4 may be provided on the display plate 2.

図３に示す第２の実施形態のように、嵌合凹部６の一端上部に係止部５を設けて表示プレート２を係止することもできる。この実施形態では、磁石３が表示プレート２の他端側底面に設けられてモールド１に吸着固定するようになっている。モールド１がアルミニウムなどの磁石３に吸着しない材質の場合は、表示プレート２を嵌合凹部６に嵌め込んだ際に磁石３が当接する部分に鉄板などの磁性吸着部４をモールド１に設ければよい。表示プレート２の着脱の方法は第１の実施形態と同様である。   As in the second embodiment shown in FIG. 3, the display plate 2 can be locked by providing a locking portion 5 at one upper end of the fitting recess 6. In this embodiment, the magnet 3 is provided on the bottom surface of the other end side of the display plate 2 so as to be attracted and fixed to the mold 1. When the mold 1 is made of a material that is not attracted to the magnet 3 such as aluminum, a magnetic attracting portion 4 such as an iron plate is provided in the mold 1 at a portion where the magnet 3 contacts when the display plate 2 is fitted into the fitting recess 6. That's fine. The method for attaching and detaching the display plate 2 is the same as in the first embodiment.

このように、本発明によれば表示プレートを確実にモールド１に固定でき、着脱も容易なので生産性を落とすことなく、正確に識別マークを付することができる。頻繁に表示プレートを交換する必要があるタイヤの成形加硫用モールドには特に好ましい。   As described above, according to the present invention, the display plate can be securely fixed to the mold 1 and can be easily attached and detached, so that the identification mark can be accurately attached without reducing productivity. It is particularly preferable for a molding vulcanization mold for a tire that requires frequent replacement of the display plate.

なお、係止部５および磁石３の位置、形状、数や表示プレート２の形状は実施形態で示したものに限定されない。     Note that the positions, shapes, and numbers of the locking portions 5 and the magnets 3 and the shape of the display plate 2 are not limited to those shown in the embodiment.
