To provide a manufacturing method for an upper case capable of preventing deformation or breakage of a molded product while using an axial draw mold in molding the upper case made of synthetic resin having an inclined cylindrical part.SOLUTION: A stationary mold 3 is provided with a first half-split body 5A, and a movable mold 4 is provided with a second half-split body 5B. The first half-split body 5A and the second half-split body 5B abut against each other on an inclined surface I. The first half-split body 5A has a first plane 6A at both ends on an inner diameter side of an inclined cylindrical part 2 on the inclined surface I, and the second half-split body 5B has a second plane 6B at both ends on the inner diameter side of the inclined cylindrical part 2 on the inclined surface I. The first plane 6A and the second plane 6B are planes that do not cause undercut when an upper case 1 is taken out from an injection molding mold M.SELECTED DRAWING: Figure 3

    【課題】傾斜円筒部を持つ合成樹脂製の上側ケースの成形において、アキシャルドロー型を用いながら成形品の変形又は破損を防止できる上側ケースの製造方法を提供する。【解決手段】固定型3に第1半割体5Aを設けるとともに、可動型4に第2半割体5Bを設ける。第1半割体5Aと第2半割体5Bは、傾斜面Iで互いに衝合する。第1半割体5Aは、傾斜面Iにおける傾斜円筒部2の内径側の両端部に第1平面6Aを有し、第2半割体5Bは、傾斜面Iにおける傾斜円筒部2の内径側の両端部に第2平面6Bを有する。第1平面6A及び第2平面6Bは、上側ケース1を射出成形金型Mから取り出す際にアンダーカットを発生させない平面である。【選択図】図3
