The invention relates to the technical field of
high polymer material injection molding and
automatic control, in particular to an intelligent injection molding parameter regulation and
control system for an
injection molding machine, which comprises a rheological digital twinning and feed-forward resolving unit, a
wavefront position prediction unit and a
control unit, the transient pulsation instruction generation unit is used for analyzing the
wavefront position prediction information and superposing a high-frequency micro-amplitude pulsation instruction into the macroscopic injection speed instruction; the high-frequency shearing thermal injection and physical
phase change unit is used for reducing the partial
melt viscosity of the
wavefront based on the high-frequency micro-amplitude pulsation instruction; the energy decoupling and state
recovery unit is used for monitoring the execution state of the high-frequency micro-amplitude pulse instruction, so that the
polymer melt is recovered to a high-
viscosity state and is cooled and solidified; the self-adaptive regulation and control and optimization unit is used for quantifying the
fine structure filling rate of the
fine structure region and optimizing the transient pulsation generation strategy according to the wave-front speed fluctuation variance; according to the method, the robustness of complete recarving and long-term
continuous production of the
fine structure is ensured.
