Kinematic calculation analysis of micro injection molding machine with double-toggle clamping mechanism based on MATLAB

Abstract

The geometric model of micro injection molding machine with double-toggle clamping mechanism is established to analyses the kinematic and mechanical performance of double-toggle clamping mechanism. The kinematic analysis of the double-toggle clamping mechanism is used to study the effects of the double-toggle parameters for the microstructure injection molding machine. The parameters discussed in this paper include the amplification ratio, velocity ratio and the amplified force ratio for the double-toggle clamping mechanism. The optimized parameters of clamping mechanism are obtained according the calculation results of stroke ratio, velocity ratio and the amplified force ratio. © the authors.
