While designing the mechanism of the great output power, considering the issues of convenience and cost in manufacture, mechanical engineers often choose the toggle mechanism made of linkages. For the sake for the wide utilization in the mold-clamping mechanism, the researcher designs a 6-link type mold-clamping toggle mechanism with two mold plates. Besides that, the researcher also applies the SQP method to the dynamic appearance of the mechanism and tries to make an optimum design in order to have the optimal size, which can decrease the vibration of the machine base effectively.
Through the analysis of the literature, there are several origins of the vibration, including the condensation of the driver, the distortion of the tie bar, the friction force, and the inertia force. The researcher uses the inertia force of the mold plates as the objective to have the optimal size of the mechanism. During the research, the stretch blow moulding machine is used as an analysis module; the CAE software, ADAMS, is utilized to do the dynamic simulation of the toggle mechanism and make the optimum design. Besides, the influences on the machine vibration by different sizes of 6-link type mold-clamping toggle mechanism are compared to those by 4-link type mold-clamping toggle mechanism used by the industry society. For the dynamic analysis of the 6-link type mold-clamping toggle mechanism, virtual work theorem used to solve the equation of motion of the mechanism system, being verified by the simulated result of ADAMS, it is confirmed the accuracy of the constructed model.
