the machine has human-computer interface ,the PLC is the main controller of the machine , the operater can set all kind of process parameter according to their own need，when set data，you only need to touch the data area of the touching interface, the keyboard will launch out automatically.
the hot chamber die casting machine has automatic action below :
die closing →injection → injection delay→injection return →cooling delay → die opening → ejection forward→ ejection backward →push off→push off back→ detect casting → spraying the die casting mould →die closing →…….
Melting zinc alloy and heat preservation of the furnace
the hot chamber zinc die casting machine has 4 kinds of furnace , internal heating electric furnace , external heating electric furnace , gas furnace and diesel furnace .
NOTE :
The combustion furnace is mainly used for heat preservation, you must pour the molten alloy into the empty crucible if the furnace has just been operated. If the combustion furnace is used for melting alloy, the less you pour alloy into the crucible, the better it is.
The crucible must be kept close with a thermal shield to avoid heat missing and to make fireproof.
With the consumption of the molten metal, those zinc pigs, which will be poured into the crucible, must be preheated properly. It is not permitted to pour damp zinc pigs into the crucible to avoid any explosive accidents. Meanwhile, those very large zinc pigs shouldn’t be poured into the crucible so that the temperature of melt can’t decline sharply.
The temperature of the molten metal should be limited within the scope of 400~430 . If the ℃ temperature is above 450 , the service life of ℃ machine parts will be shortened. In any case the temperature must not be above 500℃ , or else zinc alloy will be converted into hard zinc, which will ℃ caused the piston to be got stuck in the injection chamber.
