Dynamics of Core Taking out at Die Casting

Abstract:

The belonging amplitude and the phase characteristic and the transient characteristic are for K=1 and P=1 identical as for the action quantity. The core puller at pulling cores it is possible to consider as the regulation system with the force of cores pulling F₁ as the inlet quantity and the course of core movement x respectively the speed of core movement v as the outlet quantity. The equation of the regulation system is identical with the equation of regulation system obtained by a gradual integration from the measured course at pulling cores at the die cast. At application of the proportional regulator the amplitude, the phase and the transient characteristic of the action quantity and the control of the regulation circuit constructed on the basis of the transmission state that the circuit is stable a periodic. The amplitude, the phase and the transient characteristic of the regulation circuit defect constructed on the basis of the transmission state that the defect in the regulation circuit lowers relatively quickly.
