METHOD FOR INFERRING REAL INJECTION STROKE OF INJECTION MOLDING MACHINE, INJECTION MOLDING MACHINE AND METHOD FOR INFERRING PLASTICIZING TIME

摘要

PROBLEM TO BE SOLVED: To provide a method for inferring an accurate injection stroke of an injection molding machine to be inferred.;SOLUTION: When a type N of a resin to be used and a cavity volume V of a mold are given in a step ST11 and an inferred value of one shot mass WN is given in a step ST13, a real injection stroke can be inferred in a step ST14, Properties of the resin to be used are considered in the inferring. When the real injection stroke inferred in this flow is used, a reliable simulation to new mold and resin can be conducted, and a number of times and a time of a trial operation can be remarkably reduced as compared with a prior art.;COPYRIGHT: (C)2002,JPO
