The invention belongs to the technical field of crucible production, and particularly relates to a forming device of a lithium battery cathode material graphite crucible and a processing method. The forming device comprises a base, a top forming mold plate, an outer film cylinder and a bottom forming mold plate, the top forming mold plate is arranged on the base, a core column is fixed on the base, the top forming mold plate is in sliding connection with the core column, the lower end of the outer film cylinder is connected with the top forming mold plate or the base, and an opening in the lower end of the outer film cylinder is blocked through the top forming mold plate; and the bottom forming mold plate extends into the outer film cylinder through the opening in the upper end of the outer film cylinder. In the structure, the top forming mold plate is positioned below the bottom forming mold plate, and the core column is fixed on the base; therefore, after compression molding, the bottom of a crucible body faces upwards, so that the top of the crucible body can be prevented from being damaged in a demolding process; and meanwhile, in the pressing forming process, the bottom forming mold plate moves downwards to achieve pressing, in the way, it can be guaranteed that the crucible body obtained after pressing is compact, and the overall quality is effectively improved.
Description
technical field [0001] The invention belongs to the technical field of crucible production, and in particular relates to a molding device and a processing method of a graphite crucible, a negative electrode material of a lithium battery. Background technique [0002] The production of graphite negative electrode materials mainly uses Acheson and inner series graphitization furnaces. The graphite negative electrode materials are loaded into graphite crucibles for graphitization treatment, and the carbon atoms are transformed from a thermodynamically unstable "two-dimensional disorderly overlapping" arrangement into a "3D ordered overlapping" arrangement. [0003] With the development of electric vehicles and other electronic equipment, lithium batteries have been widely used; the negative electrode materials of lithium batteries need to use a large number of crucibles in the production process. The current crucible is usually produced by compression molding; during the compr...
