The paper presents a mathematical model that completely describes the process of impulse densification of moulding sands. The developed model consists of a set of differential equations describing the impulse head dynamics and the process of deformation and densification of moulding sands. Mathematical modelling of the dynamic squeezing process was based on the rheological model of moulding sand developed on the basis of its rheological properties identified experimentally by the time characteristics method. The developed model can be used in simulation research for selecting and optimising the parameters of impulse moulding machines, as well as for optimising the process of impulse densening of moulding sands.
