The invention discloses a pressure boost adjusting device and method based on on-line control of a die-casting machine. The device comprises an injection cylinder, a pressure boost cylinder, a cartridge flow valve, a pressure ejector controller and a servo motor, wherein the pressure ejector controller controls the boost pressure of the pressure boost cylinder through the cartridge flow valve; a pressure sensor used for detecting pressure signals is arranged in the injection cylinder, and is connected with the input terminal of the pressure ejector controller; an optical grating ruler is arranged on the injection cylinder, and is connected with the pressure ejector controller; the cartridge flow valve is connected to the pressure boost cylinder; the pressure ejector controller is electrically connected with the servo motor; and the servo motor is in transmission connection with the cartridge flow valve. The device can control the pressure boost process of the die casting machine on line, so as to enable the p
