The disassembly work can be done quickly without using auxiliary tools, thereby improving the disassembly efficiency of the mold.

[0003] The above patent has the following problems: when currently using molds for production, the metal raw materials are extruded into shape for neatness. However, when the existing molds are heated, the metal is extruded at the same time, and the metal will adhere to the inner wall of the mold during the deformation process, resulting in increased friction between the mold and the metal, making it difficult to remove the metal. Therefore, we propose a black metal mold that is easy to demold. Utility Model Content
