The die casting machine consists of the following parts.           

(1) die organization            Measures for closing and opening of die casting die. When the die is closed, the mold can be locked in order to ensure that the mold parting surface can not be expanded in the process of injection filling. The locking die force is called locking force (called locking force), unit: kn (kN), is the primary parameter characterizing the size of the die casting machine.            (2) injection organization            The metal liquid in the chamber is pushed at regular speed, and the energy is satisfied to flow through the sprue and the inner gate of the mold, and then filled into the mold cavity, and then adhere to the necessary pressure to transfer to the condensed metal liquid until the die casting stop. After the ejection action is finished, the punch is reset.            (3) hydraulic system            Provide power and energy for the operation of die casting machine.            (4) electric control system            Operate the die casting machine organization according to the booking procedure.            (5) parts and frame            All parts are assembled and assembled to form the whole die casting machine and fixed on the machine frame.            6) other equipment leading die casting machine also has parameter detection, fault alarm, die-casting process monitoring, computer aided production information storage, call, print and its management system.            (7) auxiliary equipment            According to the degree of automation equipment pouring, spraying, taking pieces and other equipment.            Modify the operation methods of all kinds of die casting machine in this section            Operation method of vertical cold chamber die casting machine            The pressure chamber 7 is placed straight, and the upper punch 8 is positioned above the pressure chamber (the position above the figure), and the lower punch 10 is located at the 5 orifice of the nozzle, so as to avoid pouring the metal liquid into the pressure chamber and automatically flowing into the nozzle hole. The opening and closing action of the die moves horizontally. After the mold opening, the die castings remain in the moving die. The operation process is as follows:            (1) closing die;            (2) pouring molten metal into the press chamber by artificial or other methods;            (3) the upper punch moves down at lower injection speed and enters the pressure chamber until the metal liquid level is touched;            (4) the upper punch is turned to a higher injection speed, and the lower punch is moved down with the interval between the upper punch and the center part of the metal liquid;            (5) the punch moves to make the nozzle orifice, just down to the bottom and be shored up; therefore, the upper and lower punches with kneading liquid metal high speed to the nozzle (part of the sprue 6) eruption;            (6) metal liquid through a nozzle, sprue 4, fixed mold taper and divider consisting of 2 sprue gate 6, from the 3 filling into the mold cavity;            (7) the end of the filling, but the upper punch still adhere to the pressure, until the metal liquid in the cavity completely condenses into the die casting 1 stop; pouring and pressure chamber of metal liquid is condensed into straight gate and residual material cake 9;            (8) the upper punch is reset, and the lower punch is moved upwards, and the remaining material which is connected with the straight gate is cut off;            (9) the lower punch continues to rise, the excess cake is listed on the top of the chamber, and then removed by artificial or other methods;            (10) reset the lower punch to the nozzle orifice;            (11) open mold, die-casting and sprue together on the moving die, then push out and remove the pressure casting; once cut off more than cake, can immediately perform the opening move, also can slightly slow until the proper time to perform, has nothing to do with the lift and reset the punch moves on the end;            So far, a die casting cycle is finished.            Operation method of horizontal cold chamber die casting machine            The pressure chamber 7 is horizontally placed, and the injection punch 5 is positioned at the right end of the pressing chamber. The opening and closing action of the die moves horizontally. After the mold opening, the die castings remain in the moving die. The operation process is as follows:            (1) closing die;            (2) pouring molten metal into the press chamber by artificial or other methods;            (3) press the ram to push the metal liquid according to the predetermined speed and the certain pressure, make it pass through the sprue 3 of the mold, fill the mold cavity from the inner gate 2;            (4) the end of the filling, the punch must keep the pressure, until completely condensed into liquid metal die casting 1 stop; then, the runner and gate 6 (for the pressure chamber is not connected in the mold gate) in liquid metal has become with condensation, gate and remainder cake 4;            (5) open the mold, the punch and mold opening move synchronously, and then push the remaining cake with die casting and gate together stay in the moving die and leave the fixed mold, arrived at certain intervals, the punch will come back reset;            (6) after mold opening, die casting, gate and leftover cake remain on the moving die, then eject and take out the die casting;            So far, a die casting cycle is finished.            Operation method of full vertical cold chamber die casting machine            The press chamber 5 is placed directly in the lower part of the machine, and the opening and closing of the die moves up and down, so it is called a full vertical die casting machine. The die of the general die is fixed on the top. After opening the die, the die is left in the moving die. The operation process is as follows:            (1) pouring molten metal into the press chamber by artificial or other methods;            (2) closing die;            (3) the punch 6 moves up and presses the metal liquid. After pouring the runner 3 and the diverter 4, the runner is filled into the mold cavity from the inner gate 2;            (4) the end of the filling, the punch must adhere to the pressure until the metal liquid completely condenses into the die casting 1 stop; at this time, the sprue and the chamber metal liquid also condenses together, and the pressure chamber becomes redundant material cake 7;
