Problems solved by technology

This design can reduce labor intensity and improve production efficiency, but the formed powder column will still be stuck in the powder-pressing mold, and the ejection operation needs to be added separately in the subsequent process, so there is still a large room for improvement in production efficiency

Abstract

The invention discloses an automatic die retreating type explosive pressing die which comprises a movable die part and a fixed die part. The fixed die part comprises a lower die plate, cushion blocksare arranged on the two sides of the top of the lower die plate, and an ejection reset mechanism is arranged at the position, located on the inner sides of the two cushion blocks, of the top of the lower die plate. The ejection reset mechanism comprises an ejection rod and a reset spring arranged on the outer side of the ejection rod, and an explosive plug is arranged at the top of the ejection rod. A cavity part is arranged above the fixed die part in a matched mode and comprises a cavity plate, the explosive plug and a guide column. An explosive groove is formed in the position, corresponding to a protrusion, of the top of the cavity plate, and the explosive plug is arranged in the explosive groove in an H7/f6 clearance fit mode. The movable die part comprises an upper die plate, a maledie and a guide sleeve, the male die is arranged at the bottom of the upper die plate, the guide sleeve is arranged on the periphery of the male die, and a protrusion is arranged at the bottom of themale die. The guide column is arranged in the guide sleeve in a matched mode, and the guide column can move along the guide sleeve.

Description

technical field [0001] The invention relates to a medicine pressing mold, in particular to a medicine pressing mold with automatic withdrawal mode. Background technique [0002] The powder pressing mold is an important equipment for pressing and forming the ammunition column. Due to the particularity of the explosive of the ammunition column, production safety and production efficiency are important considerations for the pressing powder forming process. Although the existing powder pressing mold can safely and stably produce grains that meet the basic quality requirements, but because there is no automatic mold ejection mechanism, the formed grains are stuck in the cavity and cannot be automatically ejected, which needs to be done in the subsequent process. If the ejection operation is added separately, the press needs to perform two "mold clamping-mold opening" processes to complete the molding of a shot, and it needs to be used in conjunction with the ejection frame, whic...
