The invention discloses a network exploder charging mold and an application method. The mold is split, is arranged on a network exploder and comprises an inner mold arranged on the inner side of an annular charging portion of an exploder, an annular detonation amplification hole mold arranged on the annular charging portion of the exploder and an outer mold arranged on the outer side of the annular charging portion of the exploder. The deformation of the network exploder in the process of a technology can be effectively avoided, a large amount of explosive raw materials can be saved, and the network exploder charging mold can be well applied to charging of conventional warhead network exploders including torpedoes and the like and is especially suitable for charging of large-sized network exploders.
