METHOD OF ANALYZING INJECTION MOLDING CONDITION AND METHOD FOR PROVIDING ITS ANALYZED RESULT

摘要

PPROBLEM TO BE SOLVED: To provide a method of analyzing an injection molding condition closer to the actual injection condition. PSOLUTION: The method for analyzing injection molding conditions uses mold shape data mathematically defining the shape of a mold cavity corresponding to a resin molding shape, resin passage shape data mathematically defining a resin passage shape connecting an injection device of an injection molding machine to the mold, the surface temperature of the mold cavity, property data of filling resin depending on the temperature including viscosity, and input data including injection condition data including pressure, temperature, and flow rate of the molten resin of a spool inlet part; and by taking into consideration the shape of a flow passage of an injection nozzle and the compressibility of molten resin stored in a barrel part of a cylinder, the flow characteristic of the molten resin into the mold cavity is calculated. For analysis, the following steps are executed: (1) input of shape data; (2) input of injection condition data; (3) input of barrel part condition data; (4) behavior analysis of molding resin in the mold; and (5) calculation of nozzle flow rate.
