A simple dismounting valve needle runner special cylinder, comprising a piston rod and a valve needle, a piston rod head end is fixedly connected with a valve needle buckle, the needle valve is detachably connected to the valve pin buckle, the needle valve and the piston rod are coaxially arranged, the valve needle head in the end for the glue and hot nozzle mouth, sliding the needle valve can open and close the glue inlet control of the hot nozzle opening. With the end portion of the valve needle along the radial part of the installation process of buckle slot into simple inner wall and the inner end of the arc-shaped slot, the needle valve and the piston rod to keep coaxial. The connecting way of the valve needle and the valve pin makes the two ends of the matching part of the valve needle contact with the inner cavity of the buckle part, so that the piston rod can effectively drive the needle of the valve to move. When the needle is worn out, only the pin is removed, the needle can be removed from the valve pin, and the valve needle can be replaced. The process is convenient and quick.

一种简易拆装阀针的热流道专用油缸
本专利技术涉及模具热流道
,具体涉及一种简易拆装阀针的热流道专用油缸。
技术介绍
注塑模具的热流道系统设有热咀和油缸,油缸的活塞杆固接有阀针。阀针的阀针的头端用于与热咀的进胶口配合,阀针的滑动能够控制热咀的进胶口的开闭。由于热咀的开闭切换频繁,使得阀针的头端与热咀的进胶口之间的摩擦频繁,导致阀针容易磨损。现有技术中,阀针通过螺纹连接件与活塞杆连接,使得拆卸或安装阀针的过程不便,导致模具维护的耗时长,效率低。
技术实现思路
针对现有技术的不足,本专利技术的目的是提供一种简易拆装阀针的热流道专用油缸,其能简化拆卸或安装阀针的过程。为了解决上述技术问题,本专利技术所采用的技术方案是:一种简易拆装阀针的热流道专用油缸,包括活塞杆和阀针,活塞杆的头端固接有阀针扣,所述阀针可拆卸地连接于所述阀针扣,所述阀针与所述活塞杆同轴设置,所述阀针的头端用于与热咀的进胶口配合,所述阀针的滑动能够控制所述热咀的进胶口的开闭。具体地,所述阀针扣具有扣合部,所述扣合部呈圆柱状,所述扣合部设有插槽,所述插槽沿扣合部的径向设置,所述插槽的内端封闭,所述插槽的外端 ...
