Optimum Design Of Base Die For Submersible Pump Based On HSACE

The production of plastic products is based on the development of plastic mold design and selection of plastic molding process.The quality of plastic mold design and the choice of plastic molding process directly affect the quality of plastic products.Plastic industry according to the optimization of CAE software analysis results,the use of CAD software for plastic mold design and product production has become the mainstream of the plastics industry.In this paper,a micro diving pump plastic pedestal as the object,to simulate the injection molding simulation using HSCAE software,the systematic study of the influence of mold structure and process parameters of plastic quality and production efficiency,so as to provide a basis for optimization of mold structure and process parameters.First of all,three sets of gate location schemes and three sets of cooling system structure schemes are designed and simulated respectively.The simulation results are systematically analyzed.The results show that the direct effect of gate opening position of the melt flow time,the number and size of the weld line,the temperature of the melt,melt the pressure and shear stress,the mold will be opened at the gate without gap plane side can shorten the filling time,reduce the size of the number of fusion lines,reduce the shear stress of melt therefore,improve the uniformity of temperature and pressure distribution;cooling system structure affects the distribution of heat flux density,core and cavity temperature,cooling time and cooling water temperature,cooling system of the mold design for maximum heat flux core and cavity respectively by cooling channel 1 series can the increase of the heat absorption,reduce the maximum temperature of core and cavity plastic parts,shorten cooling time,reduce cooling water and water inlet temperature.Secondly,the three groups of data are simulated with the temperature of mould,injection temperature,injection pressure and packing pressure as the variables,and the simulation results are analyzed systematically.The results show that:in the mold temperature range of 40 ?-80? in the melt filling time increases with the mold temperature and shorten the melt temperature decreases with the mold temperature,melt pressure decreases with the mold temperature,melt shear stress was decreased with the mold temperature,the optimum mold mold temperature 80?;in the injection temperature range of 200?-240? in shear stress,plane stress increases with increase of injection temperature,the shrinkage index is affected by the injection temperature is not particularly large,but still with increasing injection temperature increases,the optimal injection mold temperature is 200 ?;in the injection pressure range of 70MPa-130MPa,the shrinkage index,average plane stress and warpage with injection pressure increases,the optimal injection mold pressure is 130MPa;the pressure for The range of 65MPa-95MPa,the solidification thickness ratio increases with the pressure and change,warpage with increasing pressure decreases,the pressure is in the range of 95MPa-125MPa,the solidification thickness ratio increases with the pressure decreases,the warpage increased with pressure and change the best,die pressure 95MPa.Finally,according to the structure of HSCAE simulation optimization,the design of the die is completed.The die is tested according to the optimized process parameters,and the results of the test are verified.
