The Research of Open Mold Instantaneous Halt for the Oil Cylinder Driver Toggle Clamping Part

油缸驱动肘杆机构合模部件触动系统在注塑成型的开模过程中出现的瞬时停顿的不连续运动现象,分析了肘杆机构合模部件弹性变形能的实质,从理论和实例上对瞬时停顿的不连续运动现象进行论证,说明主要原因是由于油缸动力驱动系统与肘杆机构合模部件弹性力学的两者之间的动态性能不匹配所引起。提出的油马达—滚珠丝杆—肘杆机构等组合的传动系统,改变了合模部件弹性恢复能量转化型式,达到弹性恢复不干涉开模运动速度,实现开模的连续运动;传动系统组成型式的改变,打破传动的油缸驱动肘杆机构合模部件传动系统的增力比的设计极限,由传统的约20倍可增大到约100倍,实现肘杆机构合模部件节能降耗驱动的突破,拓展了运动性能优化设计空间。

The oil cylinder driving elbow lever mechanism clamping parts touched momentary pause in the injection molding mold continuous motion of the toggle institutions mold parts of the elastic deformation energy in real terms from the theory and examples of the instantaneous pause discontinuous motion of the demonstration, the main reason is caused due to the dynamic performance does not match the hydraulic power driven system with toggle agencies clamping parts of elasticity between the two. The institutions combination of the transmission system with the oil motor-ball screw-toggle, the proposed change to the flexibility of the mold parts to restore the energy conversion type, to achieve the flexibility to restore the non-interference in mold velocity, continuous movement of the mold; transmission system composed of the type changes, clamping parts of the fuel tank driving elbow lever mechanism to break the drive transmission system increasing power than the design limits can be increased by about 20 times to about 100 times, institutions toggle clamping parts energy saving drive breakthrough in expanding the sports performance optimization of the design space.
