Flash holes penetrating through the bottom surface of the body are formed in the closed ends of the tubular cavity bodies. Bottom surface openings of the flash holes are located in a wiring groove. A blocking groove is disposed in the wiring groove and between the bottom surface openings of the flash holes. The wiring groove is sealed with glue. The glue forms a closed ring shape along the cross section direction of a leading wire in the wiring groove, thereby blocking a channel where powder gas goes forwards along a gap, and eliminating the phenomenon of blaze. | 10-22-2015 |
