Hot-chamber die-casting machine usually works as shown.
Hot chamber die-casting machine work
Hot
chamber die casting machine furnace 10 placed in the machine, the
machine before work, the first liquid metal poured into the furnace,
with a pressure chamber and the gooseneck channel 9 and injection
punching punch 8 are immersed in the molten metal 7 . Mold opening and closing movements were horizontal movement, after the mold, die-casting remain in the dynamic mode.
Work steps are as follows:
(1) the machine head plate and mold gate sleeve and nozzle close (some machines do not have this program);
(2) Close the mold;
(3)
In the position of the shot in the figure, the molten metal from the
side of the hole into the watering cans of each space, after the flow,
gooseneck channel 6 and the liquid level in the furnace level Qi
(4) The injection plunger moves downward at a slower injection speed to seal the side holes;
(5)
high-speed injection pressure punch metal injection push, through the
gooseneck channel 6, nozzle 5 mold sprue 4, shunt 3, from the gate 2
into the mold cavity, and then solidified into Die casting 1;
(6) injection punch to enhance the nozzle and gooseneck channel liquid metal back into the watering can;
(7) Open the mold, die-casting and gate remain in the dynamic mode.And then eject and die-casting;
(8) the machine head plate and die gate sleeve away from the nozzle (some machines do not have this procedure,
At this point, to complete a die-casting cycle.
