Description

technical field [0001] The invention relates to the technical field of energetic materials, in particular to an auxiliary feeding device for filling energetic materials in a rubber mold. Background technique [0002] Compared with traditional energetic material molding products, isostatic pressing has unique advantages such as high and uniform product density and near-net molding. The basic principle is to place the powder energetic material pre-packaged in an elastic mold such as rubber or plastic in a closed container filled with liquid, and the deformation of the elastic mold when it is subjected to the pressure of the isotropic liquid medium is transmitted to the mold. Energetic material is powdered so that it can be compacted into a compact body or part with a certain density and strength. [0003] Since the surface of the outer mold is subjected to the same pressure during the isostatic pressing process, in order to avoid the uneven shrinkage of different parts of the...

Problems solved by technology

However, when the filling is completed, that is, when the mold cavity has been completely filled with powder, the separation of the feed port of the silo and the feed port of the mold will inevitably bring about powder leakage and dust, which will virtually cause environmental pollution and increase the cleaning and sprinkling operation. process, while causing harm to the physical and mental health of operators
