摘　　要：The present invention relates to a method for manufacturing lost foam and sand mold adapted for deep hole casting and a method for deep hole casting. The method includes four steps： （1） preparing a lost foam mold having at least one deep hole; （2） burying a metal tube in each of the deep holes to form a lost foam mold; （3} placing the lost foam mold into a sand box, then encapsulating the lost foam mold with sand mold material to form a sand mold adapted for deep hole casting; {4） pouring metal liquid into the sand mold, thus the lost foam evaporates and the metal liquid bonds with the metal tube and （5） removing the sand mold after the metal liquid have been cooled down and solidified to form a casting with at least one deep hole.2013-47.Method for manufacturing lost foam and sand mold adapted for deep hole casting and method for deep hole casting Patent No.:TW201306963Date of Patent:2013-02-16Inventor(s):Huang Fengshen Assignee:Huang Fengshen[CHINESE TW]The present invention relates to a method for manufacturing lost foam and sand mold adapted for deep hole casting and a method for deep hole casting.
