Description

底模升降与单边锁定联动机构
技术领域
本发明涉及饮料瓶加工设备领域，特别涉及吹瓶机上的底模升降和定位机构。
背景技术
现有技术中的吹瓶机一般包括机架、设置在机架上的左右模和底模、以及驱动机构和定位机构，如公告号为CN201755911U中公开的一种直线式吹瓶机的底模锁定装置，包括模具安装板、瓶模模腔、底模、动力机构、定位机构与支座，瓶模模腔尾段套接底模，底模连接动力机构，定位机构水平设置在支座上，定位机构包括定位卡块气缸与定位卡块，定位卡块与定位卡块气缸连接，动力机构包括底模安装板与底模升降气缸，底模安装板上表面连接底模，下表面连接底模升降气缸，底模升降气缸固定在支架上。可见，该专利中的底模锁定装置需要三个动力机构，使得能源损耗较大，且设备体积庞大。
发明内容
本发明所要解决的技术问题是提供一种改进的底模升降与单边锁定联动机构。
为解决以上技术问题，本发明采用如下技术方案：一种底模升降与单边锁定联动机构，其安装在吹瓶机上，联动机构包括底模升降组件和定位组件，底模升降组件包括可沿上下方向移动地设置在吹瓶机的机架上的升降杆，底模安装在升降杆的上端部，升降杆的上下移动由一驱动组件驱动。驱动组件包括能够绕一第一轴线转动地设置在机架上的转轴、固定连接于转轴上的凸轮、开设于凸轮上的第一滑槽、安装在升降杆上的滑动件、用于驱动转轴转动的动力源，滑动件能够滑动地插在第一滑槽中，在转轴转动的过程中，第一滑槽与滑动件接触的位置作升高或降低的变化，滑动件在第一滑槽的导向下沿上下方向移动。定位组件包括可滑动地设置于机架上的滑块、能够绕一第二轴线摆动地设置于机架上并在摆动时牵引滑块移动的摆动件、用于控制摆动件摆动的固定设置在转轴上的转动件。联动机构具有至少两个工作位置，在第一工作位置下，底模与机架之间形成一段距离，滑块插入底模与机架之间且抵住底模，在第二工作位置下，滑块离开底模，底模朝向机架移动。驱动组件在驱动升降杆带动底模升降的同时，转轴带动转动件的转动，从而通过摆动件牵引滑块的移动，以对底模定位或释放。如此，便实现了底模升降与定位的联动。
进一步地，驱动组件还包括用于连接转轴与动力源的摆臂，动力源驱动摆臂转动，通过摆臂带动转轴转动。摆臂与凸轮及滑动件位于机架的下方，因而，动力源也可安排在机架的下方，以有效利用机架下方的空间。
更进一步地，机架上开设有供转轴穿过的第一通孔和供升降杆穿过的第二通孔，使得转轴和升降杆可部分延伸机架上方、部分延伸到机架下方。
优选地，转动件、摆动件、滑块以及底模等部件位于机架的上表面的上侧。
在一特定实施例中，转动件上具有导向面，摆动件上形成有凸块，凸块与导向面可相对滑动地接触，且凸块与导向面接触的位置与第一轴线之间的距离随着转动件的转动发生变化。随着转动件的转动，借由导向面的导向作用，凸块位置移动，摆动件便可产生绕第二轴线的摆动。
进一步地，机架上形成有直线形的导轨，滑块可滑动地设置于导轨上。
优选地，滑块上形成有凸柱，摆动件上在离第二轴线一段距离处形成有第二滑槽，凸柱可滑动地插在第二滑槽中。摆动件的开第二滑槽的部分形成拨叉结构，通过该拨叉拨动滑块，使其相对机架滑动，方式简单易行。
优选地，在摆动件与机架之间设置一弹性部件，用于提供复位力给摆动件。在转动件转动的过程中，当凸块和导向面接触的位置离第一轴线越来越远时，摆动件即被转动件推着发生摆动；反之，若在转动件转动的过程中，凸块和导向面接触的位置离第一轴线越来越近，摆动件即需要外力来牵引着才能产生摆动，而此处的弹性部件即用来提供所需要的这种外力。当然，也可以通过其它方式来提供该外力，例如通过转动件牵拉摆动件的方式。
优选地，第一轴线和第二轴线最好相平行。
本发明的有益效果在于:通过一个转轴来带动定位组件和底模升降的联动，只采用一个动力源即可实现两种操作，可节省能源，减小设备体积。

附图2为图1所示结构的俯视图（底模下落）；
附图3为图2所示结构在底模被定位时的俯视图（底模上升）；
其中：1、底模；2、机架；3、定位组件；4、驱动组件；5、转轴；6、凸轮；7、转动件；8、第一滑槽；9、摆臂； 12、升降杆；13、滑动件；31、滑块；33、导轨；35、摆动件；37、凸块；38、扭簧；41、凸柱；42、第二滑槽；71、导向面。
具体实施方式
下面结合附图对本发明作进一步阐述。
图1较完整地反映了底模升降组件和定位组件的结构，这些组件安装在吹瓶机上使用，由于，吹瓶机的其它部件并不是本发明的要点，且已为本领域技术人员所熟知，因此，未在图中显示出来。图1所示的机构包括机架2、底模定位组件3、用于驱使底模1作升降运动的驱动组件4，机架2上通常还应该设置吹模组件（常用机构，图中未完整显示），吹模组件包括能够开合地设置的左右模和能够上下滑动地设置在机架2上的底模1。在开模时，左右模啮合，底模1也靠拢左右模，三者之间形成型腔，开模时三者分开，使型腔打开。
如各附图所示，驱动组件4包括能够绕自身轴心线转动地设置在机架2上的转轴5、与转轴5的下部相固定连接且其上开设有第一滑槽8的凸轮6、用于驱动转轴5转动的动力源，驱动组件4还包括用于连接转轴5与动力源的摆臂9。
底模1设置于一升降杆12的顶端，升降杆12的下部分别形成有能够沿着第一滑槽8滑动的滑动件13，如附图1所示。底模1、升降杆12和滑动件13可为一体成型的构造。
在转轴5转动的过程中，第一滑槽8接触并支撑滑动件13，随着第一滑槽8支撑滑动件13的位置作升高或降低的变化，使得滑动件13在第一滑槽8的导向下作上下方向的移动，相应地，升降杆12即带着底模1作升降运动。
在图1所示的优选实施例中，转轴5转动所围绕的转动轴线与升降杆12相对机架2的移动方向相平行，第一滑槽8相对于垂直于转动轴线的平面倾斜地延伸。此处“倾斜”的意思是指代表第一滑槽8的延伸方向的第一滑槽8的中心线不处于转轴5的同一横截面圆周上，第一滑槽8的延伸方向基本上既不平行于转轴5的转动轴线，也不垂直于该转动轴线。这样的话，在转轴5转动过程中，与第一滑槽8相滑动配合的滑动件13即在导向槽4的导向下作上下移动。
图2-3更直观地显示了定位组件3的机构。
定位组件3包括固定设置在转轴5上的转动件7、与转动件7配合的摆动件35、沿水平方向滑动地设置的滑块31，摆动件35的一端部与机架2转动连接，另一端部与滑块31相连。
具体地，转动件7上形成有导向面71，摆动件35上设置有凸块37，在转动件7转动时，凸块37与导向面71相对滑动地接触。导向面71可以为渐开线形的构造，其沿转轴5的半径所在直线的纵截面外缘与转轴5的轴心线之间的距离按顺时针方向越来越大或越来越小，当然导向面71也可以为其它曲面构造。导向面71的形成，主要是为了使凸块37和其接触的位置与转轴5的轴心线之间的距离随着转动件7的转动而变化，从而产生摆动件35的摆动。
定位组件3还包括沿水平方向设置的的导轨33，滑块31沿着导轨33滑动地设置。
滑块31上形成有凸柱41，摆动件35上形成有第二滑槽42，凸柱41可滑动地插在第二滑槽42中。摆动件35上开设第二滑槽42的部分形成拨叉结构，用于拨动滑块31在导轨33上来回滑动。
优选地，在摆动件35与机架2之间设置一扭簧38，用于提供复位力给摆动件35。参照图2-3的变化，转动件7按照逆时针方向转动，由于导向面71的导向作用，与之相接触的凸块37便可以朝靠近转轴5的轴心线（即转轴5相对机架2转动的转动轴线）的方向移动，此时，摆动件35在扭簧38的作用力下逆时针转动，摆动件35的拨叉部分带动滑块31沿导轨33移动至图3所示的位置，即：滑块31插入底模1与机架2之间并抵住底模1，对底模1形成定位。再参照图3-图2的变化，转动件7按顺时针方向转动，由于导向面71与凸块37接触的位置离转轴5的轴心线越来越远，因而凸块37被推着发生位移，在此过程中，摆动件35克服扭簧38的作用力按顺时针方向转动，并通过其拨叉部分带动滑块31移动至图2所示的位置，即：滑块31脱离底模1，从而将底模1释放。当吹模组件处于合模状态时，底模1上升至与机架2之间间隔一段距离，滑块31插设在底模1与机架2之间且在底模1的下方抵住底模1；当吹模组件开模时，动力源带动转轴5转动，转轴5带动凸轮6和转动件7转动，当转动件7转动时，凸块37沿着导向面71滑动，使得摆动件35作摆动，通过摆动件35牵引滑块31滑块31沿着导轨33滑动，继而定位组件3打开，同时凸轮6随转轴5转动，滑动件13沿着第一滑槽8滑动，使得底模1下降，从而完成开模。
上述实施例只为说明本发明的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本发明的内容并据以实施，并不能以此限制本发明的保护范围。凡根据本发明精神实质所作的等效变化或修饰，都应涵盖在本发明的保护范围之内。
