To provide a manufacturing method of an annular weather strip that can firmly fix an end part of the weather strip without worsening workability, a connection method of the weather strip, and a mold.SOLUTION: A mold which includes a body part where a cavity is formed, and a slide core 40 which extends to a second wall part 4b inside a cross-section U-shaped fitting part 4 and is removable to an opening side when a weather strip is inserted in the cavity is prepared. A manufacturing method of an annular weather strip includes: a step for removing a core material from both end parts of the weather strip; a step for inserting both end parts in the mold; and a step for softening a sheet material put in between both end parts and flowing it into a cavity part 9. At one end in a longitudinal direction of the slide core 40, a lower projection 44 projecting downward is formed opposite an opening side of a fallen rip 5. A curvature radius R2 of a recess R of a root part 44a of the lower projection 44 is set larger than the curvature radius R1 of the projection R of an end 5a of the rip 5.SELECTED DRAWING: Figure 12
【課題】施工性を悪化させず、ウェザーストリップの端部を強固に接着可能な環状ウェザーストリップの製造方法、ウェザーストリップの接続方法および金型を提供する。【解決手段】キャビティが形成された本体部と、ウェザーストリップがキャビティに挿入された場合に、断面コ字状の取付部4の内側で第2壁部4bまで延び且つ開放側へ抜き取り可能なスライドコア40と、を備える金型を用意する。ウェザーストリップの両端部から芯材を抜き取る工程と、両端部を金型に挿入する工程と、両端部で挟んだシート材を軟化させて、空洞部9に流し込む工程と、を含んでいる。スライドコア40の長手方向の一端部には、倒れたリップ5よりも反開放側で、下側に突出する下側突起部44が形成されている。下側突起部44の付け根部44aの凹Rの曲率半径R2が、リップ5の先端部5aの凸Rの曲率半径R1よりも大きく設定されている。【選択図】図12
