La principale differenza tra macchina per pressofusione a camera calda e macchina per pressofusione a camera fredda
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.
The difference between vertical die casting machine and a horizontal die casting machine is the difference in the structure of the die casting machine, that is, one is standing and the other is lying down. It is mainly manifested in the vertical die casting machine's mold is placed horizontally on the ground, and the side is fed horizontally, which is suitable for small castings.
Macchina per pressofusione orizzontale, lo stampo è perpendicolare al terreno o presenta un angolo verticale rispetto al terreno, alimentandosi generalmente dal fondo dello stampo laterale (stampo fisso).Ora la macchina per pressofusione orizzontale si sta sviluppando rapidamente e molti pezzi di grandi dimensioni sono stati completati sulla macchina per pressofusione orizzontale.
