[0027] The setting of the molding device can realize multiple processes to be completed at one time, thereby reducing these intermediate links, greatly shortening the production cycle, and thus improving production efficiency. Compared with the traditional molding device, the device that can complete multiple processes at one time can better control the operating conditions and avoid fluctuations caused by multiple transfers and equipment replacements, thereby ensuring the consistency of graphite anode molding.

When the graphite powder and the binder are mixed, the valve plate 103 is pulled upward, and the mixed raw materials flow into the molding chamber set by the molding plate 105 through the discharge port 104. When the molding chamber is filled with raw materials, the valve plate 103 is reset downward, and then the first hydraulic cylinder 106 is started, and the precision adjustment of the piston length of the first hydraulic cylinder 106 is achieved through the programmable logic controller PLC and the use of various sensors and actuators. It is explained here that PLC and sensors are both existing mature technologies, so Without further explanation, since the connecting block 107 mounted on the output end of the first hydraulic cylinder 106 is fixedly connected to the forming plate 105 by positioning bolts, the first hydraulic cylinder 106 can further drive the forming plate 105 to move on the slide rail 108. When it moves to the bottom of the forming block 304, the second hydraulic cylinder 302 is started to enable the lower pressure plate 303 to drive the forming block 304 to move downward, thereby realizing extrusion molding of the raw material in the molding cavity. After extrusion molding, the first hydraulic cylinder 106 is started to move the forming plate 105 to the curing box 400 for curing treatment, and finally the formed graphite anode plate can be taken out.
