Problems solved by technology

The main mold in explosive molding is a hard mold. When explosively pressing the powder, the powder will often spew out due to the poor sealing effect of the hard mold, which not only causes waste of resources, but also affects product quality; , after the explosion, the powder adheres to the hard mold and is not easy to demould
When using soft mold tools for explosive molding, the excessive instantaneous force generated by the explosion may directly blow up the soft mold, or because the soft mold has an indeterminate shape, the shape of the final powder material is also difficult to control.

Abstract

The invention relates to the field of explosive forming, in particular to an explosive forming mold of an active compound material. The explosive forming mold comprises a hard mold, a soft mold, a compression molding part and an explosion part, wherein the hard mold is provided with a hollow cavity; the soft mold is located in the hard mold and is provided with a cavity used for wrapping the active compound material; the compression molding part and the explosion part are located in the hard mold; under the acting force of the explosion part, the compression molding part exerts pressure on the soft mold, and achieves compression molding of the active compound material. Through the explosive forming mold of the active compound material, a method of combining the hard mold and the soft mold is adopted for compression molding of the active compound material, not only is the sealing effect of the mold improved, but also the shape of the molded active compound material is easy to control, and waste of materials is reduced.

Description

technical field [0001] The invention relates to the field of explosive molding, in particular to an explosive molding mold for active composite materials. Background technique [0002] Explosive forming is a high-energy rate forming method that uses explosive substances to release huge chemical energy at the moment of explosion to process metal blanks. Compression molding of powder materials mainly uses the explosive molding process, using the pressure of the instantaneous shock wave generated when the explosive explodes, to act on the powder to shorten the distance between particles. The main mold in explosive molding is a hard mold. When explosively pressing the powder, the powder will often spew out due to the poor sealing effect of the hard mold, which not only causes waste of resources, but also affects product quality; , After the explosion, the powder adheres to the hard mold and is not easy to demould. When using soft mold tools for explosive molding, the excessive...
