The invention provides an off-machine jacking device and method with unbalance loading resistance, a working table of a mold is placed above the jacking device, the mold is located on the working table, and the lower end of a jacking rod of the mold penetrates through the working table and then is located above the jacking device; the two bases are installed at the bottom in a foundation pit, the two bases are each provided with a hydraulic cylinder, and cylinder rods of the hydraulic cylinders are connected with the supporting plate. A set of synchronous assembly is installed between the supporting plate and the two bases, and a guide assembly is installed between each base and the supporting plate. According to the out-of-machine jacking device with the unbalance loading resisting capacity, the jacking force is 10 t or above, and the jacking force can be 40 t or above by adjusting the pressure of a hydraulic system; the perpendicularity precision of the supporting plate in the up-and-down movement process can be guaranteed through the guide assembly, and unbalance loading force generated when the supporting plate jacks up an ejector rod and a blank holder in the die can be resisted.

    本发明提供了一种具有抗偏载能力的机外顶起装置及方法,该顶起装置上方放置模具的工作台,模具位于工作台上,且模具的顶杆下端穿过工作台后位于顶起装置上方;两个所述底座安装在基础地坑内底部,两个所述底座上分别安装一套液压缸,液压缸的缸杆与托板连接;托板与两个底座之间安装一组同步组件,每个所述底座与托板之间分别安装有导向组件。本发明所述的具有抗偏载能力的机外顶起装置,顶起力在10t以上,通过调整液压系统压力可实现顶起力在40t以上;通过导向组件可以保证托板上下运动过程中的垂直度精度,并能抵抗托板顶起模具中顶杆和压边圈所产生的偏载力。
