Abstract
An injection molding adaptive compensation method based on melt viscosity fluctuation comprising: initializing equipment; in a pre-calculation stage, introducing melt into a mold cavity at a constant rate, collecting pre-calculation parameters in each sampling period T, and obtaining a first injection work in the pre-calculation stage by using a first calculation formula; in a self-adaptation stage, introducing the melt into the mold cavity at a constant rate, collecting adaptive parameters in each sampling period T, and obtaining a second injection work in the self-adaptation stage by using a second calculation formula; calling the PVT characteristics of current processing raw materials to construct a PVT relation function, and obtaining an optimized V/P switching point by using a PVT weight control model; and according to the injection work at the pre-calculation stage and the injection work at the present stage, obtaining an optimized holding pressure according to an injection work adjustment model.
