Internal high-pressure forming dynamic sealing control system and internal high-pressure forming process

The invention discloses an internal high pressure forming dynamic sealing control system and an internal high pressure forming process, the system comprises a PLC controller and a motion controller which perform data interaction through the Ethernet, the PLC controller collects the control oil pressure, the plug cavity pressure and the rod cavity pressure of a supercharger, and the control oil pressure, the plug cavity pressure and the rod cavity pressure of a first side push cylinder; the PLC controls the oil pressure, the plug cavity pressure and the rod cavity pressure of the second side pushing cylinder, and the PLC is further connected with a servo motor through a servo driver; the motion controller is connected with a supercharger displacement sensor used for detecting displacement of a supercharger piston cylinder, a first side pushing cylinder displacement sensor used for detecting displacement of a first side pushing cylinder piston cylinder, and a second side pushing cylinder displacement sensor use
