A cylindrical through hole is formed in an insert body for rotational molding along the central axis, an inlaying structure is arranged on the insert body, blind hole threads are arranged on the upper end face of the insert body, an annular sealing ring sinking groove is formed in the upper end face of the insert body, and a sealing ring is arranged in the annular sinking groove. The embedded structure is used for fixing, the sealing ring is fixed through the blind hole threads, and the anti-falling rotation step is designed on the embedded structure, so that the effect of high sealing performance is integrally achieved; the anti-drop rotating step can well prevent the insert from product leakage caused by dragging force and rotating force, and the problems in the prior art are thoroughly solved.
本发明公开了一种滚塑密封镶件,滚塑成型用的镶件本体沿中轴线设置圆柱体通孔,在镶件本体上设置镶嵌结构,在镶件本体的上端面设置盲孔螺纹,在镶件本体的上端面设置环形的密封圈沉槽,在环形沉槽内设置密封圈。本发明以镶嵌结构固定,并以盲孔螺纹固定密封圈,在镶嵌结构上又设计了防脱转台阶,以一体式实现了高密封性的效果;防脱转台阶能够很好的防止镶件因受拽脱力、转动力导致产品泄漏,彻底解决了现有技术存在的问题。
