Die casting machines are generally divided into two categories: hot press chamber die casting machine and cold pressure chamber die casting machine. The cold press chamber die casting machine is divided into two types: horizontal die casting machine and vertical die casting machine (including full vertical die casting machine) according to its pressure chamber structure and arrangement.
The pressure chamber of the hot press chamber die casting machine (referred to as the hot air die casting machine) is immersed in the liquid metal of the heat-dissolving crucible, and the injection member is not directly connected to the machine base, but is mounted on the crucible. The advantage of this die casting machine is that the production process is simple, the efficiency is high, the metal consumption is small, and the process is stable. However, the pressure chamber and the injection punch are immersed in the liquid metal for a long time, which affects the service life. And easy to increase the iron content of the alloy. Hot-pressure chamber die-casting machines are mostly used for die-casting low-melting alloy castings such as zinc alloys, but also for die-casting small aluminum and magnesium alloy die-casting parts.
The pressure chamber of the cold chamber die casting machine is separate from the holding furnace. At the time of die casting, liquid metal is taken out from the holding furnace and poured into a pressure chamber, and then die-casting is performed.
