Description

一种注塑模具用止水栓
技术领域
本发明涉及注塑模具零部件领域，特别是一种新型的注塑模具用止水栓。
背景技术
止水栓是用于塑胶模或任何水道冷却或加温系统之中，依照所需的流向配合起到有关于填塞的作用的金属零件。止水栓使用范围：塑胶模具、水道流道冷却系统、流道水道加温导热系统。
塑胶件注塑过程中，一般需要设计许多冷却或加热水路，而传统的注塑模具用止水栓是靠橡胶的膨胀进行密封的，水温较高时，容易出现漏水现象，且传统的注塑模具用止水栓需要设计运水沉头孔，再将止水栓放入其中，通常止水栓放置位置固定（如图1所示），不易变通，使用效率低下。
发明内容
为解决现有技术的不足，本发明的目的在于提供一种注塑模具用止水栓，极大简化了安装程序，并且提高了使用效率。
为了实现上述目标，本发明采用如下的技术方案：
一种注塑模具用止水栓，其特征在于，包括铜材质的套管，所述套管内设有梯形的铝材质的紧固栓，所述紧固栓由数个梯形连接而成，所述套管外均匀设有数个橡胶圈，所述每个橡胶圈正对着紧固栓中每个梯形的下底边缘，所述紧固栓内部设有膨胀螺丝，所述膨胀螺丝内部设有软质的凹槽。
一种注塑模具用止水栓，其特征在于，所述套管的材质为黄铜。
一种注塑模具用止水栓，其特征在于，所述橡胶圈为耐高温橡胶圈。
一种注塑模具用止水栓，其特征在于，所述橡胶圈厚度为0.5-1.5mm。
一种注塑模具用止水栓，其特征在于，所述凹槽的材质为橡胶。
一种注塑模具用止水栓，其特征在于，所述凹槽顶端设有矩形开孔。
本发明的原理为：1.本发明的止水栓利用不同材质的热膨胀系数，将设在内部的紧固栓运用热膨胀系数大的铝（热膨胀系=23*10-6/℃），外部的套管运用热膨胀系数较大的铜（热膨胀系=17.7*10-6/℃），在铜套管上设有耐高温橡胶圈，在升温时，铝质紧固栓迅速膨胀，进而带动铜质套管及橡胶圈的膨胀，进一步加大了套管及橡胶圈的膨胀力度；2.本发明的止水栓利用铜部件受热膨胀原理，使铜套管变形，从而与运水孔形成过盈配合，不仅能够堵水，更能够堵气，附于外层的密封圈厚度大大减小，膨胀时配合铜套管膨胀，实现了橡胶封堵和过盈密封的结合，效率大大提高。
本发明的有益之处在于：1.在高温下膨胀效果显著，能够高效的堵水、堵气；2.本发明的止水栓可以放置于运水的任何位置，安装简单，使用效率高，效果好；3.安装及取下方便简单、高效。

图3是本发明的注塑模具用止水栓结构示意图； 
图中附图标记的含义：
1.套管，2.橡胶圈，3.紧固栓，4. 膨胀螺丝，5. 凹槽，6.止水栓。
具体实施方式
以下结合附图和具体实施例对本发明作具体的介绍。
结合图2和图3，本发明的注塑模具用止水栓6，包括黄铜材质的套管1，所述套管1内设有梯形的铝材质的紧固栓3，所述紧固栓3由5个梯形连接而成，所述套管1外均匀设有4个橡胶圈2，所述橡胶圈2的厚度为0.5mm，所述每个橡胶圈2正对着紧固栓3中每个梯形的下底边缘，当高温膨胀时，下底膨胀能够带动橡胶圈2的进一步膨胀，所述紧固栓3内部设有膨胀螺丝4，所述膨胀螺丝4内部设有橡胶材质的凹槽5，所述凹槽5顶端设有矩形开孔（图中未示出），能够配合止水栓安装工具进行高效的安装。
本发明的注塑模具用止水栓6，除上述结构外，其不同之处在于，所述橡胶圈2为硅橡胶圈，能够耐高温，提高了使用效率；所述套管1材质为红铜；所述橡胶圈2的厚度为1mm。
本发明的注塑模具用止水栓6，除上述结构外，其不同之处在于，所述橡胶圈2的厚度为1.5mm。
本发明运用到的止水栓安装工具，包括安装杆及安装头，所述安装头截面为矩形，能够自由穿过凹槽5顶端的矩形开孔，所述安装头端头设有爪钩，其爪钩在不使用时收起位于安装头端头内，使用时通过按键及牵引线的控制爪钩展开，形成鱼钩状端头，从而牢牢抓住矩形开孔外侧，用以将止水栓拉出运水管。
本发明的注塑模具用止水栓通过实验证明，其封堵效果显著，可承受60kg/cm2的水压，并可用于封堵150~200℃的蒸汽，本发明的止水栓可安装于运水管的任何位置，可以有效的减小模芯钻空的加工，提高水路排布及钳工的加工效果。
以上显示和描述了本发明的基本原理、主要特征和优点。本行业的技术人员应该了解，上述实施例不以任何形式限制本发明，凡采用等同替换或等效变换的方式所获得的技术方案，均落在本发明的保护范围内。
