Vacuum forming die of graphite block

The invention discloses a vacuum forming die of a graphite block. The vacuum forming die comprises a workbench which is provided with a column; the column is provided with an extrusion base and a sliding block and is also provided with an ejector plate; the workbench is provided with a lower shaft; the lower shaft is provided with a hollow column and an exhaust opening and connected with a lower die; the extrusion base is provided with a forming die which is provided with a forming hollow column; an upper shaft is connected between the ejector plate and the sliding block; the upper shaft is connected with an upper die; the ejector plate is connected with a hydraulic workstation which is connected with a hydraulic device through a liquid conveying pipe; the exhaust opening is connected with a gas conveying pipe which is connected with an electromagnetic valve, a valve, a vacuum tank, a dustproof device and a vacuum pump. According to the vacuum forming die of the graphite block, the structure is skillful, the operation is simple and convenient, the functions are practical, the rebound release value of the graphite block after being removed can be effectively reduced from 1.6 to 0.8%, the subsequent processes are reduced, the density and the quality of the graphite block are improved, and the environment-friendly effect is achieved.
