Description

Technical Field

[0001] This utility model belongs to the field of explosive manufacturing technology, and relates to cleaning and wiping of explosive pressing molds, specifically to an automatic mold wiping device suitable for the lower or upper punch of the mold. Background Technology

[0002] Before use, ammunition (explosives) needs to be molded. During the molding process, the upper and / or lower punches of the mold come into direct contact with the ammunition, leaving ammunition adhering to the surface. Therefore, to ensure safe production and the quality (smooth surface) of the product after the next molding, the upper and / or lower punches and the inside of the mold cavity are usually cleaned after the ammunition is molded. This removes any residue from the mold, preventing any residual ammunition from posing a danger during secondary molding, and ensuring a smooth surface for the propellant grains after the next molding, thus guaranteeing a high product qualification rate. Currently, mold cleaning is mainly done manually, which cannot guarantee the cleaning effect, and improper handling of the cleaned ammunition poses a safety hazard.

[0003] Chinese patent CN 221183869 U discloses an automatic cleaning device for the cavity of a medicated powder pressing mold. During the entire cleaning process, the lower punch of the mold can be removed from the mold cavity, making the mold cavity open and allowing the cleaning rod to fully enter the mold cavity. This thoroughly cleans the powder adhering to the inner wall of the mold cavity, thus automating the cleaning of the mold cavity. However, this device does not clean the upper punch and / or lower punch of the mold. Therefore, it is necessary to provide an automatic cleaning device suitable for the lower or upper punch of the mold. Summary of the Invention
