Description
【考案の詳細な説明】 本考案はダストカバーの成型金型装置の改良に係る。[Detailed explanation of the idea] The present invention relates to an improvement of a molding device for a dust cover.
例エバ自動車のサスペンション用ポールジヨイントに泥
水等の異物が侵入するのを防止するためにダストカバー
を装着している。For example, a dust cover is attached to the suspension pole joint of an Evangelion car to prevent foreign matter such as muddy water from entering.
該ダストカバーに設けられているシールリップ部はボー
ルジヨイントのスタッド部と密封摺動するので、ボール
ジヨイントの揺動によって変形し易い。Since the seal lip portion provided on the dust cover slides in a sealed manner with the stud portion of the ball joint, it is easily deformed by swinging of the ball joint.
これを防ぎ追随性を向上させるため、シールリップ部に
ワッシャー状の補強リングを加硫接着してこの部分を補
強している。In order to prevent this and improve followability, a washer-shaped reinforcing ring is vulcanized and bonded to the seal lip to reinforce this area.
第１図に示すダストカバー１のシールリップ部２に補強
リング３が加硫接着されている。A reinforcing ring 3 is vulcanized and bonded to a seal lip portion 2 of a dust cover 1 shown in FIG.
この加硫接着作業を成型金型装置により行なう場合、前
記補強リング３を中子７に設けた複数本のピン８によっ
て成型用キャビティ内に保持した状態でゴム材料を注入
する。When this vulcanization adhesion work is performed using a molding device, the rubber material is injected while the reinforcing ring 3 is held in the molding cavity by a plurality of pins 8 provided on the core 7.
前述の成型用キャビティは、例えば下金型６と中金型５
と中子７によって形成されている。The above-mentioned molding cavity includes, for example, the lower mold 6 and the middle mold 5.
and the core 7.
またゴム材料は中金型５の上部に設けたポット部に充填
され、上金型４の圧下により前記キャビティ内に注入さ
れる。Further, the rubber material is filled into a pot provided at the upper part of the middle mold 5, and is injected into the cavity as the upper mold 4 is pressed down.
この際、前述のように補強リング３を保持しているピン
８の近傍のゴム材料の流れが不均一となり、この部分に
ガスキズが発生し易い欠点がある。At this time, as described above, the flow of the rubber material near the pin 8 holding the reinforcing ring 3 becomes uneven, and there is a disadvantage that gas scratches are likely to occur in this area.
本考案の目的は上述の従来の欠点を解決したダストカバ
ーの成型金型装置を提供することである。The object of the present invention is to provide a molding device for a dust cover which solves the above-mentioned conventional drawbacks.
本考案は第２図に示すように、中子７に設けた補強リン
グ支え用ピン８にガス抜き用の貫通孔９を適当数設け、
この孔９を中子７の中も貫通させる。As shown in FIG. 2, the present invention provides a reinforcing ring support pin 8 provided on the core 7 with an appropriate number of through holes 9 for venting gas.
This hole 9 is also passed through the inside of the core 7.
このようにすることによってピン８で補強リング３を支
持している部分に溜捷ろうとするガスを前記貫通孔９を
通じて成型金型装置の外部へ排出させることができる。By doing so, the gas that is to be accumulated in the portion where the reinforcing ring 3 is supported by the pin 8 can be discharged to the outside of the mold apparatus through the through hole 9.
したがって従来前記支持部分に生じていたガスキズを防
止することができる。Therefore, gas scratches that conventionally occur on the support portion can be prevented.
第１図はダストカバーの断面図、第２図は本考案のダス
トカバ二成型金型装置の断面図である。FIG. 1 is a sectional view of the dust cover, and FIG. 2 is a sectional view of the dust cover two-molding mold device of the present invention.
