This article mainly introduces some operating requirements of aluminum alloy die casting machine, let’s take a look!

1. Strictly monitor the die casting process

The temperature of the aluminum water in the holding furnace should be controlled at ±3°C in order to stabilize the stirring temperature. The temperature after stirring must be adjusted according to the chemical composition of each furnace to ensure that the solid phase rate is stable at ±2%. The temperature of the mold must be checked and controlled so that the alloy is filled smoothly and solidified in an orderly manner. It is necessary to reasonably formulate and adjust the process parameters of the die-casting machine in a timely manner, and check the die-casting parts regularly to ensure the quality of the die-casting parts.

2. Precautions for spraying operation of release agent

Pay attention to the amount of release agent paint, avoid too much paint, too little or omission of paint. More paint can be sprayed on the parts where the casting is difficult to demold, and less paint is sprayed on the parts that are easy to demold. When spraying paint, use the spray gun to move layer by layer from top to bottom, let the water accumulated in the cavity flow from top to bottom, and blow the excess water out of the cavity. For the parts where the cavity is easy to stick to the mold, spray at a short distance to cool down, and then spray at a longer distance to form a coating film. Do not spray too close to it to prevent the paint water from flowing in the cavity. After spraying, use air to blow off the excess and accumulated paint in the cavity, especially pay attention to the paint in the deep cavity or the dead corner, to prevent the water from vaporizing into a large amount of gas when heated, causing porosity in the casting , Under-casting, cold isolation, and blistering, which play a very important role in eliminating porosity in castings.

3. Precautions for hot film of die casting machine

After using the mold temperature machine hot mold, when you start the die-casting hot mold, you can use the liquid alloy low-speed die-casting hot mold 5-10 molds, and then use the normal semi-solid alloy and semi-solid die-casting parameters for die-casting production, which can protect the mold. It can also prevent flashing and flying materials.
