CAE Simulation and Treatment of Sintering Defects in Cylinder Heads with Complex Internal Cavity Structures
By using the casting CAE sand shooting simulation software to conduct sand shooting simulation calculations on the complex inner cylinder head water jacket sand core,it was analyzed that the sand density is low and not dense in the water jacket sand core injector hole area after sand shooting,which is the main reason for the occurrence of sintering in the inner cavity of the casting.Based on the calculation and principles analysis of the nozzle area and exhaust area on the sintering area,the specifications and layout of the nozzle and exhaust plug were optimized and adjusted.Then,sand injection simulation calculation and analysis were carried out.Finally,the implementation plan for the rectification of the nozzle and exhaust plug on the mold was determined.Through production verification,the sand core has been formed completely and densely after rectification,with no sand sticking in the casting cavity,no sintering in the fuel injector hole area.The cleanliness of the inner cavity of the casting has been significantly improved.
