Abstract:
(EN) Provided is a manufacturing method for manufacturing a sliding contact ring optimal for gasket assembly. Addition reaction type polysiloxane, a curing catalyst, silicone oil, and a filler are kneaded together to form a silicone rubber G before curing. The silicone rubber G before curing is put inside an accommodation space 41 of a mold K. The silicone rubber G is pressed by a plunger 42 into a cavity 43 from a gate 44. The cavity is filled while the blended silicone oil is caused to bleed onto the surface of the fluid comprising the silicone rubber G that enters the cavity in the process of being pressed. The silicone rubber G that has been pressed inside the cavity 43 is cured to form a sliding contact ring 19 with the silicone oil bled onto the surface thereof. After the curing, the sliding contact ring 19 is removed from the mold K.
(FR) L'invention concerne un procédé de fabrication permettant de fabriquer une bague de contact coulissante optimale pour un ensemble joint d'étanchéité. Un polysiloxane du type à réaction d'addition, un catalyseur de durcissement, de l'huile de silicone et une charge sont malaxés ensemble pour former un caoutchouc de silicone (G) avant durcissement. Le caoutchouc de silicone (G) avant durcissement est placé à l'intérieur d'un espace de réception (41) d'un moule (K). Le caoutchouc de silicone (G) est pressé par un piston (42) dans une cavité (43) à partir d'une porte (44). La cavité est remplie alors que l'huile de silicone mélangée est amenée à s'écouler sur la surface du fluide comprenant le caoutchouc de silicone (G) qui pénètre dans la cavité dans le processus de pression. Le caoutchouc de silicone (G) qui a été pressé à l'intérieur de la cavité (43) est durci pour former une bague de contact coulissante (19) avec l'huile de silicone qui s'est écoulée sur la surface de celle-ci. Après le durcissement, la bague de contact coulissante (19) est retirée du moule (K).
(JA) ガスケット組み立てに対して最適の摺接リングを製造するための製造方法を提供する。 付加反応型ポリシロキサンと、硬化触媒と、シリコーンオイルと、充填材とを混練して硬化前のシリコーンゴムGを形成する。硬化前のシリコーンゴムGを金型Kの収納空間41内に投入する。前記シリコーンゴムGをプランジャ42で押圧してゲート44からキャビティ43に圧入する。圧入される過程で流入するシリコーンゴムGの流動体の表面に、配合されたシリコーンオイルをブリードさせつつ充満させる。キャビティ43内で圧入されたシリコーンゴムGを硬化させて表面にシリコーンオイルがブリードした摺接リング19を形成する。硬化後、金型Kから摺接リング19を取り出す。
