The protruding mould isnot easy toprocess out, soadopt grade enter the mould and process (this pair ofmoulds are for 3pieces ofengineering location ) and wash holes first ,and then send tointact blanking and realize the taking shape ofthe part twice bymaking the protruding mould up, only inthis way avoid washing the trouble ofthe direct blanking wide crossbeam after holes. Grade enter precision ofmould expect very much and lead demanding tobevery accurate, the obstruction that itisvery great tomeet while designing this pair ofmoulds isthrough and gets rid ofand chooses this scheme tothe choice ofevery scheme finally. Through the striving of nearly three weeks, this each enters mold design tofinish a
