VERFAHREN ZUM AUSWERTEN DER ANALYSE DES FLUSSES EINES GESCHMOLZENEN SPRITZGIESSMATERIALS

摘要

A molten injection-molding method is applicable to any system of dividing a molded product form model into micro-elements and analyzing a molten material flow behavior within the mold by the use of numerical analytic techniques that include the finite element method, boundary element method, difference method, and FAN method, among others. First, the entire length of time required for the process of filling the mold with a molten material is divided into an arbitrary number of intervals, representing the filling progress in each individual time interval in an equitime curve diagram. This is followed by next not only deriving the distance segmented by each pair of adjacent equitime curves based on interrelations of the divided micro-element and equitime curves, but also computing the individual filling speeds, and then making a graphic display on display equipment of the variations in these filling speeds over an entire filling cycle, in order to evaluate, and find, the filling speeds at which an optimum mold filling cycle may be achieved.
