1. The necessity of servo casting of die casting machineThe full hydraulic die casting machine is a typical cyclic working equipment. It can be roughly divided into mold clamping, soup, shot, core pulling, mold opening, thimble, cooling, and storage in a complete working cycle (process process). Pressing several stages, each stage is to pump hydraulic oil through the oil pump motor to each cylinder to drive the transmission mechanism to complete a series of actions, each stage requires different pressure and flow. For the hydraulic system, the pressure and flow matching are different at each s...
