Abstract:

In order to reduce the overall energy consumption of the injection molding process with hydraulic pulsation, the effect of axial vibration of screw on the energy consumption of each stage in the molding process is investigated. Then, a mathematical model is established to describe the melted plastic crossing through the pipe runner, and the corresponding energy consumption formula is deduced. Moreover, the influence of axial vibration amplitude of screw on the overall energy consumption is analyzed. Theoretical analysis and experimental results show that （ 1 ） the overall energy consumption of the injection molding process decreases due to the introduction of vibration force field; （2） the energy consumption decreases with the increase in axial vibration amplitude in a certain range; and （3） there is an optimal amplitude corresponding to the lowest energy-consumption.
