Discussion on the Core Box Process Design for Commercial Vehicle Engine Cylinder Heads
The impact of core box process design on casting quality,production efficiency,and core box weight reduction through real production cases.Finally it was pointed out:(1)Core box mold design must consider quality,efficiency,and cost factors.(2)The parting surface,venting,sand shooting mechanism,core venting needles,and chill design significantly affect core quality and should be thoroughly considered in the design process.(3)Flexible use of loose pieces,reasonable core parting surface design,and arranging electric heating rods in the hot core box according to the core structure could effectively improve production efficiency.(4)For large and thick cores,weight reduction designed should be implemented.If demolding was convenient,the thick parts could be directly thinned.If demolding was difficult,core extraction technology could be used to downgauging the sections.
