具体实施方式
下面结合附图及实施例对本发明作进一步描述：
图1-2较完整地反映了根据本发明实施的一种单轴开合模与底模锁定联动机构，该机构安装在吹瓶机上，由于吹瓶机为已知设备，因此，各图仅显示了与本发明有关的部分组件，未完整显示整个吹瓶机。
图1-2中所示的联动机构包括开合模组件、驱动组件。以下具体对各个组件做详细描述：
开合模组件包括底模1、设置在吹瓶机的机架上的定模板2、与定模板2配合的动模板3。开合模组件具有开模状态和合模状态，当处于合膜状态时，定模板2与动模板3配合、底模1上升、三者之间围成型腔，定模板2和动模板3上分别装配有模具4。
开合模组件还包括用于在合模状态时将定模板2、动模板3锁定的锁模机构，具体的说：动模板3上设置有多个第一连接凸台30，相邻两个第一连接凸台30之间形成缺口，第一连接凸台30上开设有销孔31，销孔30上下贯穿第一连接凸台30；定模板2上设置有与第一连接凸台30相配合的第二连接凸台20。锁模机构包括贯穿在定模板2内部的连接轴5、与连接轴5相传动连接的锁销6，锁销6的数量与第二连接凸台20的数量相同，锁销6能够伸缩地设置在第二连接凸台20内，连接轴5、锁销6相平行的设置，连接轴5通过连杆7与锁销6相传动连接，并且位于最下部一个锁销6与驱动块8相直连。
合模时，使动模板3的第一连接凸台30伸入至定模板2的第二连接凸台20的缺口内，向上拉动驱动块8，使驱动块8驱动连接轴5传动锁销6伸出第二连接凸台20、伸入第一连接凸台30的销孔31内，定模板2、动模板3锁定。
该机构还包括当底模1上升，将其锁定的底模锁定组件，如图3-4所示：底模锁定组件包括转动件17、与转动件17相传动连接的摆动件18以及与摆动件18相传动连接的滑块19。三者的具体连接关系为：摆动件18的一侧具有凸部180，转动件17上具有导向面170，凸部180能够在导向面170上滑动；摆动件18的另一侧开设缺口，在该缺口部位构成拨叉部181，滑块19的上具有凸柱190，凸柱190能够滑动的设置在拨叉部181的缺口内，摆动件18能够转动的设置在机架上。
摆动件18与机架之间设置有扭簧9，用于提供复位力给摆动件18。如图1、图4-5中所示。在转动件17转动的过程中，当凸部180和导向面170接触的位置离第二轴线越来越远时，摆动件18即被转动件17推着发生摆动；反之，若在转动件17转动的过程中，凸部180和导向面170接触的位置离第二轴线越来越近，摆动件18即需要外力来牵引着才能产生摆动，而此处的扭簧9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17牵拉摆动件18的方式。
此外，在机架上设置有朝底模1下部延伸的导轨21，滑块19滑动设置在导轨21上。
在本实施例中：驱动组件包括能够绕自身轴心线方向转动的转轴12、驱动转轴旋转的动力源，转轴12的下端部连接有驱动摆臂13，动力源通过驱动摆臂13驱动转轴12转动。动模板3、转动件17同时与转轴12相固定连接，并且转轴12穿过动模板3并带动其转动。如图2、4所示：当要合模时，动力源驱动驱动摆臂13传动转轴12转动，从而动模板3随转轴12转动，和定模板2相靠拢并共同围成型腔；底模1上升，底模1与支架14之间形成空隙；转动件17也随转轴12转动，凸部180沿着导向面170滑动，摆动件18转动，带动滑块19上的凸柱190在拨叉部181内滑动，从而带动滑块19沿着导轨21其部分滑动至底模1与支架14之间的空隙中，完成底模1锁定。反之亦然，再次不再进行详细描述，从而实现开合模、锁定联动。
机架包括支架14、位于支架14上方的顶架15以及固定连接在支架14和顶架15之间的立架16，开合模组件、底模锁定组件位于支架14的上侧。转轴12的上端部与顶架15相转动连接。
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。
