What Is Hot Chamber Die Casting – The Define Of Hot Chamber Die Casting
The Define Of Hot Chamber Die Casting :Hot chamber die casting means that the pressure chamber is immersed in the liquid metal of the heat preservation melting crucible, and the injection part is not directly connected to the machine base, but is installed on the crucible
The Define Of Hot Chamber Die Casting :Hot-chamber die-casting machine refers to a die-casting machine in which the injection chamber and the injection punch are immersed in molten metal, and the injection chamber is connected to the gate of the die-casting mold through a gooseneck. It is suitable for die-casting zinc, lead and other low melting point non-ferrous alloy parts, and can be widely used in automobile, motorcycle accessories, instrumentation, daily hardware, household appliances and other industrial sectors.
The Advantage Of Hot Chamber Die Casting
There are many advantages in casting aluminum and magnesium alloys by hot chamber die casting machine. When hot chamber die casting machine is used to die cast alloys with higher melting point than zinc alloy, production efficiency can be improved and automatic pouring can be realized Reduce casting cost.
The pressure chamber structure of this hot chamber die casting machine is the same as that of the die casting machine for casting low melting point alloys. Gooseneck is also an ordinary structure, but due to the use of special materials and improved high-temperature strength, the foot is increased by an inch. The advantages of hot chamber die casting are as follows:
- Die-casting of low-melting-point alloys is usually the mainstay, and zinc alloys are the most typical;
- It is suitable for the production of small die castings, and hot chamber die casting is not suitable for medium and large die castings;
- The molten metal filled into the mold cavity always flows in the closed channel, and the oxidized inclusions are not easily involved, which is beneficial to the quality of the die casting;
- The automation of the die casting process is easy to realize;
- Since the pouring procedure is not required, the production efficiency is high under normal operation;
- The specific pressure of injection is slightly lower, and there is no pressurization stage in the injection process, but it has little effect on small and thin-walled parts;
- The life of hot-worked parts such as injection punches, pouring pots, and nozzles is difficult to grasp and control, and it is time-consuming to replace after failure;
- When replacing or repairing the furnace, it is necessary to disassemble and assemble the hot-worked parts, which increases the auxiliary time;
- For the hot chamber die casting of high melting point alloys, magnesium alloys are still more suitable at present, and the hot chamber die casting machines used for magnesium alloys also have the above characteristics.
The Characteristics Of Hot Chamber Die Casting Machine
The injection cylinder and pressure chamber of the hot chamber die casting machine are arranged vertically, and the pressure chamber sinks into the molten metal in the crucible of the furnace. There is no air in the pressure chamber, and there is relatively little chance of getting involved in the gas during the injection process. Liquid metal flows in closed pipes, with small temperature fluctuations and small opportunities for oxidation inclusions. Lower pouring temperature can be used, and the quality of liquid metal can be improved.
Hot chamber die casting machines are mostly used in the production of thin-walled die castings. In addition, the process of liquid metal is long, the force loss is large, and the pressurization effect is not as obvious as that of cold chamber die casting machines. Therefore, hot chamber die casting machines are generally not equipped with pressurization hydraulic cylinders. Due to the long-term sinking of the pressure chamber components into the liquid metal, the hot chamber die-casting machine is generally only used for the production of zinc and magnesium alloy die castings that are less corrosive to the pressure chamber components. Without additional pouring operation, the hot chamber die-casting machine saves cycle time and has higher production efficiency than the cold chamber die-casting machine. The hot chamber die casting machine needs to heat the gooseneck, injection pipe and other parts to prevent being blocked by cold materials.
The Difference Between Cold Chamber Die Casting Machine And Hot Chamber Die Casting Machine
Die casting is metal die casting on a die casting machine, and it is the casting process with the highest production efficiency at present. Die-casting machines are divided into two categories: hot-chamber die-casting machines and cold-chamber die-casting machines.
Cold chamber die casting machines are divided into horizontal die casting machines and vertical die casting machines (including full vertical die casting machines) according to their 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 preservation melting 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 will affect the service life and easily increase the iron content of the alloy. Hot press chamber die-casting machines are currently mostly used for the production of low-melting-point materials such as die-casting zinc alloys and magnesium alloys.
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. Aluminum die castings, which are widely used today, can only be produced on cold chamber die casting machines due to their high melting point.
