Slapper detonator with injection-molding structure

Abstract

The invention discloses a slapper detonator with an injection-molding structure, which comprises a gun barrel component, a base, an exploding foil and a flyer; the gun barrel component comprises a gun barrel, a charging ring, an exploding foil positioning sleeve and a bonding pad, and is integrally formed by injection-molding; and the exploding foil, the flyer and the gun barrel are filled with plastic for compressing. The gun barrel, the charging ring, the exploding foil positioning sleeve and the bonding pad are integrally designed, and formed by injection-molding; and the gun barrel component welded with the exploding foil is secondarily injection-molded, so that the stability and the firmness in compressing are ensured, the number of parts is reduced, the production efficiency and the quality conformity of products are improved, the cost is greatly reduced, and the slapper detonator is expected to achieve wide application.

Description

technical field [0001] The invention relates to a detonator, in particular to a shock plate detonator with an injection molding structure. Background technique [0002] The principle of action of the shock plate detonator requires that its parts cannot have gaps in the axial direction and must be pressed tightly. The current solution is to use the elastic deformation force of the component material itself to achieve axial compression. The problem with this method is that the amount of elastic deformation is not easy to control, and once the elastic deformation becomes permanent deformation, the axial compression cannot be guaranteed. , reducing the reliability of the shock plate detonator. [0003] Shock-blade detonators have a large number of parts and require high dimensional accuracy, and most of the parts are manufactured by mechanical processing, which is difficult to process, high in cost, and has a long development cycle, which restricts the popularization and applic...
