Abstract


Finite element simulation of the mold temperature field in the die-casting process for optimizing the casting process parameters to improve the quality of the casting , and extend the life of the die has an important role to promote the development of the die casting industry . This article provides an overview of the research status and development trend of the temperature field simulation of the die casting process , and the finite element method and simulation software were introduced , a the casting molds transient temperature field three-dimensional finite element model , using the finite element analysis software ANSYS , the typical thin wall aluminum die casting mold temperature field simulation and experimental data measurements . On this basis , the switch box die casting mold temperature field simulation study . The paper simulates analysis typical thin-walled box die casting mold temperature distribution and the measured experimental and simulation results and the actual results are consistent , the maximum error of 10% , the validation of the finite element analysis software ANSYS, thin-walled parts die casting mold temperature the feasibility of field simulation , provides a reliable basis for the use of the method of thin wall switch box mold temperature field simulation study . This article analyzes the pouring temperature of 650 ° C under conditions , when the mold preheating temperature of 180 ° C , 200 ° C , 220 ° C , and under the conditions of a preheating temperature of 200 ° C , when the pouring temperature of 630 ° C , respectively , 650 ℃, 670 ℃ , the distribution of the temperature field in the switch box casting molds . By analyzing the results of the simulation of the temperature field , considering that the average heating rate of the mold cavity surface of the mold cavity , of the switch box casting preheat temperature 200 ° C mold temperature of 650 ° C pouring more reasonable . The results of the actual production of a strong guiding significance .
