Description

本発明は、フィルター付きガスケット及びその製造方法に関するものであり、更に詳しくは、自動車、産業機械器具、ガスコンロ等の家庭用機器に幅広く利用されるフィルター付きガスケットに関するものである。   The present invention relates to a gasket with a filter and a method for manufacturing the same, and more particularly to a gasket with a filter widely used in household equipment such as automobiles, industrial machinery and gas stoves.

従来、フィルター付きガスケットは、金属薄板にプレス加工により微細孔（メッシュ）を形成し、この微細孔（メッシュ）を形成した金属薄板の外周にゴム状弾性材製ガスケットを一体成形する方法により製作していた。   Conventionally, a gasket with a filter is manufactured by a method in which a fine hole (mesh) is formed in a thin metal plate by pressing, and a rubber elastic material gasket is integrally formed on the outer periphery of the thin metal plate in which the fine hole (mesh) is formed. It was.

この為、金属薄板にプレス加工により微細孔（メッシュ）を形成する事に経費が嵩むと同時に、金属薄板とゴム状弾性材製ガスケットを一体化する為に、金属薄板の表面に接着剤を塗布する手間が必要となった。   For this reason, it is expensive to form fine holes (mesh) in the metal thin plate by pressing, and at the same time, an adhesive is applied to the surface of the metal thin plate in order to integrate the metal thin plate and the rubber elastic material gasket. It took time to do.

特に、金属薄板の表面に接着剤を塗布する工程において、金属薄板全体を接着剤浴の中に浸す方法が、作業効率の観点から望ましいが、接着剤が微細孔を塞ぐ問題を惹起した。   In particular, in the step of applying the adhesive to the surface of the metal thin plate, a method of immersing the entire metal thin plate in the adhesive bath is desirable from the viewpoint of work efficiency, but the adhesive has caused a problem of blocking the fine holes.

この為、手作業である刷毛塗りにより、金属薄板の表面に接着剤を塗布する方法を採らざるを得ず、作業効率が大きく低下した。   For this reason, the method of applying an adhesive to the surface of a thin metal plate has to be taken by brushing, which is a manual operation, and the working efficiency is greatly reduced.

以下、本発明を実施するための最良の形態について説明する。
本発明の第１の態様に係るフィルター付きガスケット４は、図１及び図２に示す様に、円盤状の網部１１と、この網部１１の外周を取り囲む環状フランジ部１２とを備えたポリアミド樹脂材製のフィルター部材１と、フランジ部１２に一体形成された環状のゴム状弾性材製ガスケット２より構成されている。
ガスケット２は、フランジ部１２の外周部を包み込む様に、フランジ部１２と一体化されている。 Hereinafter, the best mode for carrying out the present invention will be described.
As shown in FIGS. 1 and 2, the filter-equipped gasket 4 according to the first aspect of the present invention is a polyamide provided with a disk-shaped net part 11 and an annular flange part 12 surrounding the outer periphery of the net part 11. The filter member 1 is made of a resin material and an annular rubber-like elastic material gasket 2 formed integrally with the flange portion 12.
The gasket 2 is integrated with the flange portion 12 so as to wrap around the outer peripheral portion of the flange portion 12.

この様な構成としている為、接着剤を使用する事無く、フィルター部材１とガスケット２を一体化出来る為、製造コストを低く抑えると共に、網部の形状の自由度を増やし、信頼性が高いフィルター付きガスケットを安価に提供出来る。   Because of this structure, the filter member 1 and the gasket 2 can be integrated without using an adhesive. Therefore, the manufacturing cost is kept low, the degree of freedom of the shape of the mesh is increased, and the filter is highly reliable. Attached gasket can be provided at low cost.

また、本実施態様においては、網部１１がドーム形状を呈している様に、網部１１の材料がポリアミド樹脂材である為、網部１１の形状の自由度を増やす事が出来、各種用途に適した、ドーム形状以外の平板形状、角錐形状等の各種形状のものを容易に得られ、信頼性が高いフィルター付きガスケットを安価に提供出来る。   Moreover, in this embodiment, since the material of the mesh part 11 is a polyamide resin material so that the mesh part 11 is exhibiting the dome shape, the freedom degree of the shape of the mesh part 11 can be increased, and various uses It is possible to easily obtain various shapes such as a flat plate shape other than the dome shape and a pyramid shape, and to provide a highly reliable gasket with a filter.

ポリアミド樹脂は、アミド結合の繰り返し単位を備えた線状高分子で、代表的なポリアミド樹脂として６ナイロン、６，６ナイロン等が有る。
この種ポリアミド樹脂は、接着剤無しで直接、ゴム状弾性材と接着一体化出来る為、接着剤処理工程を省くことが出来る。
この為、製造コストを低く抑えると共に、信頼性が高いフィルター付きガスケットを安価に提供出来る。 The polyamide resin is a linear polymer having an amide bond repeating unit, and typical nylon resins include 6 nylon, 6, 6 nylon, and the like.
Since this type of polyamide resin can be directly bonded and integrated with the rubber-like elastic material without an adhesive, the adhesive treatment step can be omitted.
For this reason, the manufacturing cost can be kept low, and a highly reliable gasket with a filter can be provided at low cost.

また、この種ポリアミド樹脂層３に、接着性添加剤成分を含ませる事により、ゴム状弾性材との接着力をより高める事が出来る。
この為、より信頼性が高いフィルター付きガスケットとすることが出来る。 Moreover, the adhesive force with a rubber-like elastic material can be further increased by including an adhesive additive component in this kind of polyamide resin layer 3.
For this reason, it can be set as the gasket with a filter with higher reliability.

ガスケット２に使用されるゴム状弾性材料としては、エチレンプロピレンジエン三元共重合体（ＥＰＤＭ）、フッ素ゴム（ＦＫＭ）、水添加ニトリルゴム（ＨＮＢＲ）、ニトリルゴム（ＮＢＲ）、天然ゴム（ＮＲ）、アクリル酸エステルゴム（ＡＣＭ）等が適宜選択して用いられる。   Rubber-like elastic materials used for the gasket 2 include ethylene propylene diene terpolymer (EPDM), fluorine rubber (FKM), water-added nitrile rubber (HNBR), nitrile rubber (NBR), and natural rubber (NR). Acrylic acid ester rubber (ACM) or the like is appropriately selected and used.

尚、本発明に係るフィルター付きガスケットの製造方法は、まず、射出成形により網部１１と、この網部１１の外周を取り囲む環状フランジ部１２とを備えたポリアミド樹脂材製のフィルター部材１を製作し、ついで、このフィルター部材１のフランジ部１２の外周側を包み込むように、金型を用いてゴム状弾性材製ガスケット２を一体成形するものである。
環状フランジ部１２には、孔が２ヶ所設けられ、成形時の位置決めに利用している。 In the method for manufacturing a gasket with a filter according to the present invention, first, a filter member 1 made of a polyamide resin material having a mesh part 11 and an annular flange part 12 surrounding the outer periphery of the mesh part 11 is manufactured by injection molding. Then, the rubber elastic material gasket 2 is integrally formed using a mold so as to wrap the outer peripheral side of the flange portion 12 of the filter member 1.
Two holes are provided in the annular flange portion 12 and are used for positioning during molding.

また、ガスケット２の外周には、外周から径方向外側に突出したガイド突起２１が形成されている。
このガイド突起２１の存在により、ガスケット２の組み付け後に、ガスケット２の有無を確認出来る為、ガスケット２の組み付け忘れを防止出来る。 In addition, a guide protrusion 21 that protrudes radially outward from the outer periphery is formed on the outer periphery of the gasket 2.
Due to the presence of the guide protrusions 21, the presence or absence of the gasket 2 can be confirmed after the gasket 2 is assembled, so that the assembly of the gasket 2 can be prevented from being forgotten.

また、フィルター部材１を成形金型内で正確に位置決めする為の位置決め用突起１３がフィルター部材１の外周部に複数個形成されている点において、第１の態様と相違している。
この位置決め用突起１３の存在により、フィルター部材１を成形金型内で正確に位置決め出来る為、精度の良いフィルター付きガスケットを容易に得られる。 Next, the filter-equipped gasket 4 according to the second aspect of the present invention will be described with reference to FIGS.
The difference from the first aspect is that the shape of the filter member 1 is a disk shape that is stretched in the vertical direction in the figure, and the net portion 11 of the filter member 1 is not a net shape but a punching metal shape. It is a point.
Further, the second embodiment is different from the first embodiment in that a plurality of positioning projections 13 for accurately positioning the filter member 1 in the molding die are formed on the outer peripheral portion of the filter member 1.
Due to the presence of the positioning projections 13, the filter member 1 can be accurately positioned in the molding die, so that a highly accurate gasket with a filter can be easily obtained.

ついで、本発明の第３の態様に係るフィルター付きガスケット４を、図５及び図６に基づき説明する。
第１の態様と相違する点は、フィルター部材１の形状が、円盤形状を呈している点と、第２の態様と同様に、フィルター部材１を成形金型内で正確に位置決めする為の位置決め用突起１３をフィルター部材１の外周部に複数個形成している点である。 Next, the gasket 4 with a filter according to the third aspect of the present invention will be described with reference to FIGS.
The difference from the first aspect is that the shape of the filter member 1 has a disk shape, and the positioning for accurately positioning the filter member 1 in the molding die as in the second aspect. A plurality of protrusions 13 are formed on the outer peripheral portion of the filter member 1.

ついで、本発明の第４の態様に係るフィルター付きガスケット４を、図６及び図７に基づき説明する。
第１の態様と相違する点は、フィルター部材１の形状が、円盤形状を呈していると共にフィルター部材１の網部１１が網目形状では無く、パンチングメタル形状である点と、第２の態様と同様に、フィルター部材１を成形金型内で正確に位置決めする為の位置決め用突起１３をフィルター部材１の外周部に複数個形成している点である。 Next, the filter-equipped gasket 4 according to the fourth aspect of the present invention will be described with reference to FIGS.
The difference from the first aspect is that the shape of the filter member 1 has a disk shape and the net part 11 of the filter member 1 is not a mesh shape but a punching metal shape, and the second aspect Similarly, a plurality of positioning projections 13 for accurately positioning the filter member 1 in the molding die are formed on the outer peripheral portion of the filter member 1.

また、本発明は上述の発明を実施するための最良の形態に限らず、本発明の要旨を逸脱することなくその他種々の構成を採り得ることはもちろんである。   The present invention is not limited to the best mode for carrying out the invention described above, and various other configurations can be adopted without departing from the gist of the present invention.

本発明に係るフィルター付きガスケットは、自動車、産業機械器具、ガスコンロ等の家庭用機器に幅広く利用される。   The gasket with a filter according to the present invention is widely used in household equipment such as automobiles, industrial machinery, and gas stoves.
