Description
技术领域
本发明涉及用于注塑金属模具用热流道系统所用的多段位置控制用汽缸的构造,特别涉及通过简化多位置形汽缸组件,由活塞的特殊构造来控制位置,可确保安全性、经济性及简单化的用于热流道系统的多段位置控制用汽缸及其制造方法。
背景技术
一般来说,用一个金属模具使用一种原料来制造产品,然而随着技术的发展,以至于可向一个金属模具内同时注入或依次注入2-3种树脂来强化制品的特性,并提高生产效率。
因这种技术的发展带来热流道系统上所用的汽缸凸现出应使其位相呈多样性变化的必要性。
然而,至此可用的多位置形汽缸是将几个汽缸重叠安装的,这样的方法导致构造复杂,且汽缸设置时受设置空间的限制,因此,实际上对制品的适用性极为有限。
发明内容
本发明是为解决上述问题而提出的,其目的在于提供一种用于热流道系统的多段位置控制用汽缸及其制造方法,该汽缸的构成是在阀组件上加工出多段式承插汽缸的通孔,装配了活塞的汽缸能够按多段式设置,从而设计出使多段位置控制用汽缸和活塞以最简单构造进行动作的装置,且可按多段位置的需要,仅增加汽缸和活塞的数目,就可简单地制作多段位置用阀组件。
为了解决上述问题,本发明由以下步骤构成,这些步骤包括:在组件本体上多段式地形成汽缸安装用通孔的步骤;在一次汽缸上开设空压供给孔、空压排出孔及防真空孔的步骤;把一次汽缸插入多段式通孔内部下端并连接的步骤;把一次活塞装配到一次汽缸内部的步骤;在二次汽缸上开设二次供给孔和空压排出孔的步骤;把二次汽缸连接到一次汽缸上端、并在上端部构成下降时使用的供给孔的步骤;用阀杆固定装置把阀杆固定到二次活塞上的步骤;把二次活塞装配到二次汽缸内部的步骤和安装汽缸盖的步骤。
下面,参照附图详细说明本发明。
附图说明
图1是本发明优选实施例的注塑金属模具用热流道系统所用的多段位置控制用汽缸的剖面图;
图2是示出本发明的多段位置控制用汽缸的动作前的状态的剖面图;
图3是示出本发明的多段位置控制用汽缸的一次活塞动作后的状态的剖面图;
图4是示出本发明的多段位置控制用汽缸的二次活塞动作后的状态的剖面图。
具体实施方式
图1是本发明优选实施例的注塑金属模具用热流道系统所用的多段位置控制用汽缸的剖面图,图2是示出本发明的多段位置控制用汽缸的动作前的状态的剖面图。图3是示出本发明的多段位置控制用汽缸的一次活塞动作后的状态的剖面图,图4是示出本发明的多段位置控制用汽缸的二次活塞动作后的状态的剖面图。
如上图所示,本发明的装置是在组件本体1的内部多段式地形成汽缸安装用通孔2,把一次汽缸3和一次活塞4装配到该通孔2内部,再在其上部多段式地设置二次汽缸5和二次活塞6,把阀杆7连接到二次活塞6,在其下部设置阀杆固定装置8来固定阀杆,阀杆固定装置8的下端位于一次活塞4的上端,而在阀杆固定装置8和一次活塞4之间形成防真空孔9,把汽缸盖10连接到二次活塞6的上面。未说明的符号11表示活塞下降用气孔,12、13表示活塞上升用气孔,14、15表示一次空压供给孔。
作为本发明的实施例,在需要三次位置时,再把三次汽缸和三次活塞各自安装到二次汽缸的上部,即使进行三次位置控制,也能够得到与本发明完全相同的效果。
下面,说明这种构成的本发明的动作方法。
当为使一次活塞4在一次汽缸3内上升,而向空压供给孔注入空压时(空压或油压可按要求选择),一次活塞4因空压作用而上升。
此时,因为设置在一次活塞4上的阀杆固定装置8的下端部连接于一次活塞4,所以阀杆7随着一次活塞4的上下动作而作上下运动。
即,一次活塞4向上推动阀杆固定装置8,至一次阀杆位置。此时,由于二次汽缸5的底面控制了一次活塞4的位置,因此,阀杆7长期停留在规定位置上。
在一次活塞4动作后的状态下,因二次活塞6的动作,使固定着阀杆的阀杆固定装置8向上移动,因此,阀杆作第二段动作。
另外,在二次汽缸5的上部和下部设置了供气管。因此,在想使二次活塞6动作到二次位置的情况下,经二次空压供给孔作用空压。于是,二次活塞6使阀杆固定装置8上升,到达二次位置。
在此状态下,在欲关闭各阀门的情况下,向活塞下降用气孔供给空气。于是,由于二次活塞6下降,因此,阀杆固定装置8一起下降,与此同时,一次活塞4也下降。
阀杆固定装置8使上述一次活塞4下降回到原来位置。另外,留在一次汽缸3的汽缸室内的空气从空压排出孔排出。此时,为了防止汽缸室内发生真空,妨害一次活塞4的动作,利用防真空孔来防止形成真空状态。
以上说明了本发明的优选实施例,但该技术领域的普通技术人员在不超出权利要求所记载的本发明构思及领域的范围内可对本发明作各种各样的修改及变更。
如上所述,本发明是在阀组件上以多段式构成承插汽缸的通孔,装配了活塞的汽缸能够按多段式设置,因此,构造简单,制作容易,能够设计出多段位置控制用汽缸和活塞,使其以最简单构造进行动作,同时可按多段位置需要,仅增加汽缸和活塞的数目,就能够简单地制作多段位置控制用阀组件。
