摘　　要：分析使用Pro/E软件设计注射模时塑件公差采用基孔制与基轴制会导致成型零件不合格的问题,提出并验证采用对称公差解决问题的办法,并用实例演示不同情况下塑件建模时为取得对称公差的具体操作过程,对使用Pro/E软件设计注射模的成型零件具有重要作用。The forming components can be off specification when their tolerances are set based on hole basis or shaft basis system by using Pro/E software. A method was put forward and examined in which symmetric tolerance was applied to solve the problem. The operating procedures in getting a symmetric tolerance during the modeling process of component under various conditions were illustrated.
