    The invention relates to foundry, in particular to machines for the injection molding of a vertical assembly. The purpose of the invention is to improve the quality of castings and the reliability of the machine. Before pouring the metal through line 14, inert gas is supplied to the cavity 15 and the metal line 9 and form 3 are purged from the air. When a dose of melt is dispensed, inert gas is supplied to furnace 12 from line 13, and a pressure is created in line 14 that is greater than pressure in line 13. The magnitude of this pressure differential is regulated and controlled by differential pressure.

    The invention relates to foundry, in particular to machines for casting under the pressure of the vertical assembly
    The aim of the invention is to improve the quality of castings and the reliability of the machine.
    Fig "1 shows the machine, a vertical section; FIG. 2 is a diagram of a gas supply system.
    An injection molding machine with a vertical layout comprises a fixed lower plate 1 and a movable upper plate 2E between which a mold 3 is installed, having a cavity 4.
    8 pressing chamber 5 is located pressing piston 6 fixed on rod 7. Pressing chamber 5 through hole 8 and metal conductor
    9 is connected to the crucible 11 with the molten metal 10. The crucible 11 is installed in a sealed furnace 12, which is connected via a main line 13 to the gas supply system. Through a line 14, an inert gas is supplied to a cavity 15 located at the top of the metal pipe 9. The pressure difference between the lines 13 and 14 is monitored by a regulating differential pressure gauge 16. A displacement sensor 17, electrically connected
    with an inert gas supply system, mounted on the rod 7 of the cylinder 18.
    The inert gas supply system 19 via line 13 includes a high pressure regulator 20, a low pressure regulator 21, a solenoid valve 22, a throttle 23 and a check valve 24. The inert gas supply system through a line 14 includes a high pressure regulator 25, a low pressure regulator 26 , a two-channel electric valve 27, a three-channel electric valve 28, one of the channels of which communicates with the atmosphere, an electric cable - a large flow section pan 29, a throttle 30, a check valve 31,

    flow meter 32, electro-valve 33, electro-valve 34, throttle 35, and electrical contact 36 controlling the level of the melt in cavity 15. Valves 27 and 28 provide pressure control in line 14 compared to line 13 by means of a differential pressure gauge 16.
    The machine works as follows.
    When the mold 3 is opened to remove the casting, the furnace 12 is connected through the electro-valve 22 to the atmosphere, the press piston 6 is in the lower position, and in line 14 by means of a differential pressure gauge 16, pressure P | greater than the pressure P2 in line 13. The inert gas from line 14 through the choke 30 and the solenoid 33 enters the cavity 15.
    After the mold is closed, it is purged with an inert gas to remove air.
    When a fill command is given, the solenoid valve 33 is closed, the solenoid valves 22 and 29 are opened, the gas from line 13 through the flow controller enters the furnace 12, and the melt is displaced up the metal pipe. Opening the solenoid valve 29 prepares the system for supplying a higher pressure P to the cavity 15. In the event of any malfunction in the gas supply system, when the melt in cavity 15 reaches the electrical contact 36, the solenoid valve 34 is turned on, which prevents the penetration of the melt into the pneumatic system. i
    After a given dose of melt has been dispensed, the cylinder 18 is pressed. After the pressing piston 6 overlaps the orifice 8 by command from the displacement sensor 17, the solenoid valves 22 and 33 open and the melt is drained from the metal conduit, since the pressure P is maintained large compared to the pressure P2 created in the furnace 12. The inert gas is accelerated into the cavity 15 The discharge of the melt along the metal conduit prevents the melt from flowing out through the hole 8 onto the rod 7 of the pressing cylinder and prevents air from flowing into the metal conductor when the melt is drained.
    After the mold is filled with the melt and the casting is solidified, the mold 3 is opened and the piston 6 pushes the press residue; all valves remain in the same position as when the melt dose was dispensed.
    When the piston returns to its lower position after opening 8, the solenoid valve 29 is closed and the gas under low pressure through the throttle 30 and the solenoid valve 33 enters the cavity 15, purging the mold 3 and the pressing chamber 5.
    The machine is ready to repeat the cycle. Difference of pressure Р and Р „composition10
