Abstract


The paper through the physical and numerical simulation of gas -assisted injection molding melt / gas delay time and the relationship between gas means a new \The results show that : under the same conditions as in the other process conditions , as the delay time increases , the maximum amplitude and the longest finger length decreases . FM new truck interior roof handle traditional molding and gas -assisted injection molding numerical simulation analysis using Moldflow software . The results show that : the gas -assisted injection molding compared with traditional molding process , the injection pressure of the melt reduced 48.8% , The clamping force decreased by 54.4% to improve product strength , eliminate shrinkage and warpage of the products . New FM truck roof interior handle physical simulation of gas -assisted injection molding mold design . The analysis was carried out according to the numerical simulation of the selection and optimization of the gate ; side core-pulling mechanism and intake components designed according to the characteristics of parts of the actual production mold design provide important guidance for the products, gas -assisted injection molding .
