Die casting machine is mainly composed of mold closing mechanism, injection mechanism, hydraulic system and power control system. In addition, die casting machine also has parts and components and frame, other devices, auxiliary devices and other parts.

Working principle of die casting machine:

(1) At the beginning of the slow injection movement in the first stage, the hydraulic oil of the system enters the cavity through the oil circuit integrated plate, and then enters the cavity through the channel, so as to push the injection piston to the left to achieve the slow injection.

(2) Two-stage rapid injection movement. When the injection punch exceeds the sprue of the barrel, the control valve of the accumulator opens, and the hydraulic oil enters the cavity rapidly through and through the sprue. The volume of the hydraulic oil in the cavity increases rapidly, and the injection speed increases.

(3) Three-stage supercharging movement of metal liquid filling into the cavity, immediately terminated, alloy liquid began to solidified, then the punch forward resistance increases, controlled by the computer program, the use of accumulator control valve open, through the rapid entry into the cavity, so as to promote the pressurized piston and piston rod left fast move. When the piston rod and floating piston inside and outside cone joint, truncated, so that the formation of a closed chamber, pressurized piston, piston rod, floating piston and the pressure of the chamber together to obtain a pressurized effect of the piston.

(4) slow, fast and pressurized fast and slow time policy can be adjusted by the oil circuit board control oil valve () the role of the hydraulic transmission system: through the hydraulic components (power components, executive components, control components, auxiliary components, working medium) and loop transmission power, so as to achieve a variety of actions.
