Peamine erinevus kuuma kambri survevalu masina ja külma kambri survevalu masina vahel
Generally ,Die casting machine including hot chamber die casting machine and cold chamber die casting machine .Cold chamber die casting machine are divided into two types according to the structure and arrangement of the press chamber: horizontal die casting machine and vertical die casting machine (including ful 4-xxxl vertical die casting machines) .
The pressure chamber of the hot chamber die casting machine is immersed in the liquid metal of the heat preservation and melting crucible, and the injection part is not directly connected to the machine base, but is installed on the crucible. The advantages of this die-casting machine are that the production process is simple, the efficiency is high, the metal consumption is low, and the process is stable. However, the pressure chamber and the injection punch are immersed in liquid metal for a long time, which affects the service life. Most of the hot chamber die casting machines are currently used for die casting low melting point alloy castings such as zinc alloys, but they are also used for die casting small aluminum and magnesium alloy die castings.
The pressure chamber of the cold chamber die casting machine is separate from the holding furnace. During die casting, the liquid metal is taken out of the holding furnace and poured into the pressure chamber for die casting.
The feeding system of the cold chamber die casting machine is independent of each other, and each injection is fed by an external mechanism (or manually). The external mechanism has a feeding hopper or a quantitative feeding furnace. The feeding system of the hot chamber die casting machine is integrated with the die casting machine, and a part of the feeding mechanism is "soaked" in the solution.
Vertikaalse survevalumasina ja horisontaalse survevalumasina erinevus seisneb survevalumasina struktuuri erinevuses, st üks seisab ja teine lamab. See väljendub peamiselt selles, et vertikaalse survevalumasina vorm asetatakse maapinnale horisontaalselt ja külg söödetakse horisontaalselt, mis sobib väikeste valandite jaoks.
Horisontaalne survevalumasin, vorm on maapinnaga risti või maapinna suhtes vertikaalse nurga all, tavaliselt toidetakse külgvormi põhjast (fikseeritud vorm).Nüüd areneb horisontaalne survevalumasin kiiresti ja paljud suured tükid valmivad horisontaalse survevalu masinaga.
