一种侧进料口的针阀式热嘴
本技术涉及模具
,具体涉及一种侧进料口的针阀式热嘴。
技术介绍
热流道针对不同的流道会使用不用的热嘴,热嘴可分为开放式热嘴和针阀式热嘴,阀针式热嘴具有良好的换色性能,适合大多数塑胶,流动性能好,极细微的浇口痕迹等,阀浇口热流道系统塑料模具结构最复杂,它与普通多头热流道系统塑料模具有相同的结构,另外还多了一套阀针传动装置控制阀针的开、闭运动,用传动装置实现阀针的开、闭运动,控制熔融状态塑料注入型腔。现有技术中的针阀式热嘴结构较复杂,大多为直进料的方式,而针对侧进料口的针阀式热嘴,存在嘴头的更换拆卸不方便以及阀针的伸出长度不便于调节的情况。
技术实现思路
为解决上述存在的问题,本技术提供一种侧进料口的针阀式热嘴。一种侧进料口的针阀式热嘴,包括热嘴本体,所述热嘴本体内设置有胶料流道,所述热嘴本体表面嵌有加热线,所述热嘴本体左端固定设置有嘴头,嘴头与热嘴本体相通,所述热嘴本体右端固定连接分流板,所述分流板上方设置有进胶口,所述进胶口下端通过进胶通道连通胶料流道,上端连通外部的流道,所述分流板横向设置有第一通孔,所述分流板右端固定设置有气缸,所述气缸横向设置有第二通孔,所述气缸包括调节杆和活塞,所述调节杆左端通过螺纹连接活塞,所述调节杆左端嵌有阀针,阀针的针杆延伸至嘴头处,所述调节杆右端伸出至气缸右端外侧。作为本技术的进一步方案:所述加热线呈不规则环状设置在热嘴本体表面。作为本技术的进一步方案:所述嘴头通过螺纹与热嘴本体连接。作为本技术的进一步方案:所述气缸通过螺钉连接分流板。作为本技术的进一步方案:所述活塞设置在气缸腔体内并与腔体配合。作为 ...
