FIELD: process engineering.
SUBSTANCE: invention relates to metal forming. Proposed lower die consists of lower die sections bolted together in interface surface. Interface surface of sections is arranged at fillet formed by taper undercut at one of said sections. Said taper undercut features height not exceeding 0.1 mm and has vertex directed toward lower die working surface.
EFFECT: tight abutment of sections and ruled out metal leaks between interface between sections in explosive correction.
