中文摘要：通过理论分析与具体数据计算，得出镶块锻模的镶块与模座配合间隙是一个与镶块大小，模具的温升以及镶块与模座的温差等诸多因素有关的可变数值。镶块越大、模具温度越高(不能高于400 ℃)，这个间隙值越大。
英文摘要：Theoretical analysis and specific data calculation shows that, the gap between insert and mold base of inserted forging die is related to the size of insert, the mold temperature as well as the temperature difference of inserts and mold base. The larger the inserts, the higher the mold temperature (not higher than 400 ℃), the greater the gap value.
