Description

一种缓冲定位的模具装配导向结构
技术领域
本发明涉及机械领域,特别是涉及一种缓冲定位的模具装配导向结构。
背景技术
在模具领域,常用导套与导柱来作为模具的导向装置,用来保证上、下模以准确的位置关系对合。由于上模与下模之间不断做相对运动,所以导柱与导套之间必须有一定的间隙以确保无障碍运动,现有的模具都是导柱、导套作线或者面摩擦的相对运动,间隙过大会导致定位不准确,误差大;间隙过小则会增大摩擦、使导柱导套的磨损严重,减少了使用寿命,增大了成本投入,而且导柱导套的更换相当麻烦。有鉴于此,迫切需要一种新型的、误差小、定位容易、耐用的导向装置。
发明内容
本发明的目的在于克服现有技术中存在的上述问题,提出一种缓冲定位的模具装配导向结构,通过多级缓冲接触,可以在装配过程中不断的适时调整,壁免直接的刚性接触,提高了使用寿命和装配精度。
本发明的目的通过下述技术方案来实现:
一种缓冲定位的模具装配导向结构,包括:上模和下模,所述上模和下模的结合面间分别具有上导向结构和下导向结构,所述上导向结构包括:上座,所述上座底部具有定位柱和过渡支撑柱,所述过渡支撑柱底部具有上座缓冲柱,所述下导向结构包括筒状的下座,所述下座底部具有下缓冲柱,所述下缓冲柱顶部具有中具有中间座,所述中间座呈L状结构,所述L状结构的横部表面通过中间缓冲结构设置有顶座,所述顶座表面具有平面移动结构,所述L状结构的竖部内具有铰接缓冲机构,所述铰接缓冲机构一端位于顶座底部,所述铰接缓冲机构另一端位于上座缓冲柱下方,所述L状结构的竖部顶部具有端面移动结构,所述上座在上下移动过程中过滤支撑柱与端面移动结构接触或分离,所述下座周向设有若干定位连杆,所述定位连杆中部与下座铰接,所述定位连杆上端设置有定位块,所述定位连杆下端位于中间座底部,所述中间座上下运动过程中使定位连杆相对下座转动,从而使定位块与定位柱接触或分离,当接触时推动上座水平运动实现定位,从而使上模和下模实现定位,所述上模和下模在定位接触后通过锁定机构进行锁定。
作用为优选 ,所述定位连杆呈弯曲状。
作用为优选 ,所述下缓冲柱为空气弹簧。
作用为优选 ,所述定位柱呈上大下小的圆台状结构。
作用为优选 ,所述中间座的侧面具有锥度定位面。
作用为优选 ,所述铰接缓冲机构包括支撑横杆,所述支撑横杆铰接在下座之上,所述支撑横杆一端位于顶座底部,所述支撑横杆另一端铰接有转动杆,所述转动杆与上座缓冲柱接触或分离。
作用为优选 ,所述支撑横杆位于下座部分呈向上翘起的弯曲状结构。
作用为优选 ,所述中间缓冲结构包括设置于中间座表面的定位筒,所述定位筒中穿设有支柱,所述支柱设置于顶座底面,所述支柱外套状有缓冲弹簧。
作用为优选 ,所述平面移动结构为滚动球或端面轴承。
作用为优选 ,所述上座缓冲柱为空气弹簧。
根据上述技术方案,本发明的有益效果是:

3、通过设置定位连杆和定位块使中间座在下移的过程中自动适应装配位置。
4、通过设置平面移动结构和端面移动结构使定位柱的自适应阻力最小。

具体实施方式
下面结合具体实施例和附图对本发明作进一步的说明。
为了使本发明的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本发明进行进一步详细说明。应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明
如图1-2为本发明一种缓冲定位的模具装配导向结构的实施例,一种缓冲定位的模具装配导向结构,包括:上模101和下模102,所述上模101和下模102的结合面间分别具有上导向结构1和下导向结构2,所述上导向结构1包括:上座11,所述上座11底部具有定位柱12和过渡支撑柱13,所述过渡支撑柱13底部具有上座缓冲柱14,所述下导向结构2包括筒状的下座21,所述下座21底部具有下缓冲柱22,所述下缓冲柱22顶部具有中具有中间座23,所述中间座23呈L状结构,所述L状结构的横部表面通过中间缓冲结构24设置有顶座25,所述顶座25表面具有平面移动结构26,所述L状结构的竖部内具有铰接缓冲机构27,所述铰接缓冲机构27一端位于顶座25底部,所述铰接缓冲机构27另一端位于上座缓冲柱14下方,所述L状结构的竖部顶部具有端面移动结构28,所述上座11在上下移动过程中过滤支撑柱13与端面移动结构28接触或分离,所述下座21周向设有若干定位连杆29,所述定位连杆29中部与下座21铰接,所述定位连杆29上端设置有定位块291,所述定位连杆29下端位于中间座23底部,所述中间座23上下运动过程中使定位连杆29相对下座转动,从而使定位块291与定位柱12接触或分离,当接触时推动上座11水平运动实现定位,从而使上模101和下模102实现定位,所述上模101和下模102在定位接触后通过锁定机构进行锁定,所述定位连杆29呈弯曲状,所述下缓冲柱22为空气弹簧,所述定位柱12呈上大下小的圆台状结构,所述中间座23的侧面具有锥度定位面231,所述铰接缓冲机构27包括支撑横杆,所述支撑横杆铰接在下座21之上,所述支撑横杆一端位于顶座25底部,所述支撑横杆另一端铰接有转动杆,所述转动杆与上座缓冲柱14接触或分离,所述支撑横杆位于下座21部分呈向上翘起的弯曲状结构,所述中间缓冲结构24包括设置于中间座表面的定位筒,所述定位筒中穿设有支柱,所述支柱设置于顶座25底面,所述支柱外套状有缓冲弹簧,所述平面移动结构26为滚动球或端面轴承,所述上座缓冲柱14为空气弹簧,所述定位柱12底面为球面结构,所述上座缓冲柱14的弹性模量小于下缓冲座22的弹性模量,也即上座缓冲柱14的硬度较下缓冲座22较小。
使用时,在上座11下移过程中,上座缓冲柱14首先与铰接缓冲机构27此时具有一定的弹性阻力,在继续下移过程中,定位柱12与平面移动结构26平稳接触,接触后继续下移,此时上座缓冲柱14穿过端面移动结构28,使过渡支撑柱13底面与端面移动结构28相接触,然后中间座23断续整体下移,使中间座推动定位连杆29转动,从而使定位块与定位柱相接触并可推动其整体平面移动,由于定位块291设置于定位柱12周向,最终使之在若干定位块291围成的中心定位,实现了定位需求,此时中间座继续下移,使上模101和下模102最终完成装配定位要求。
以上所述仅为本发明的较佳实施例而已,并不用以限制本发明,凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等,均应包含在本发明的保护范围之内。
