Oil-electric hybrid hot-chamber die casting machine injection system

The invention relates to an oil-electric hybrid hot-chamber die casting machine injection system, which comprises a melting pot sleeve, an injection rod, a servomotor controller and a hydraulic pressurizer, a servomotor drives the injection rod in order to control the injection speed in the process of injection, and the hydraulic pressurizer cooperates with the servomotor controller to drive the injection rod in order to control rapid pressurization in the process of injection. The injection speed is controlled by the servomotor, the servomotor controls multi-stage slow speed, uniform acceleration, multi-stage high speed, speed reduction and braking in the process of injection, and can realize the multi-stage stepless regulation of the injection speed, consequently, the flashless function of die casting is realized, and high-quality net-shaped products can be shaped. Meanwhile, a hydraulic system is utilized to carry out pressurization, pressurization is independently controlled, which can help to shorten the
