摘　　要：内螺纹接头模具使用非标准模架,取消推出机构,在模架上安装液压电机、蜗轮蜗杆、齿轮机构等,由液压电机驱动螺纹型芯旋转使成型塑件脱模。为了防止塑件跟随螺纹型芯旋转,在塑件的外圆柱面上设置止旋槽,在推件板和动模板之间安装弹簧,螺纹型芯旋转时弹簧将推件板推开,防止螺纹型芯与推件板摩擦,限位螺钉限制推件板与动模板之间分开的距离小于螺纹长度,可以防止塑件在旋转结束时弹力集中在螺纹末端而导致螺纹损坏的现象。The internal thread joint mould used a non-standard mould base,the ejection mechanism was canceled,hydraulic electric machine,worm wheel and worm,and gear mechanism were installed on the mould base,and the demoulding of plastic part was driven by the hydraulic electric machine to rotate the threaded core.In order to prevent the plastic part from rotating with the threaded core,a stop spinning groove was arranged on the outer cylinder of the plastic part.A spring was installed between the ejector plate and the moving half of mould plate,when the threaded core rotated,the spring would push the ejector plate away to prevent friction between the threaded core and the ejector plate.The limiting screw limited the distance between the ejector base plate and the moving half of mould plate to be less than the thread length,which could prevent the elastic force of the plastic part from concentrating on the end of the thread at the end of the rotation,resulting in damage to the thread.
