In modern production technology, die casting is a very common production form. Common die castings are aluminum alloy die casting and zinc alloy die casting. Today, Longhua Technology will briefly introduce the principle of die casting:

Die-casting: (Press-casting) is to quickly press a liquid or semi-liquid alloy into a mold cavity under high pressure, and solidify under pressure to obtain a casting;

1. Inject metal First close the mold cavity, and inject metal liquid into the mold inlet through the injection hole on the pressure chamber; 2. Die-casting The injection punch advances, and the metal liquid is pressed into the mold cavity;

3. Take out the casting. After the casting is solidified, the core pulling mechanism pulls out the cores on both sides of the cavity at the same time.

Remarks:

1. The mold cavity is made of a special alloy tool steel (such as 3Cr2W8V2), that is, the mold steel;

2. The cavity should be maintained at 120-280 ° C during die casting (depending on the specific die casting material);

3. The specifications of the die casting machine are generally expressed by the size of the clamping force;

Of course, there is still a lot of knowledge involved in the process of die casting. It is impossible to understand everything in a small article. This time I just let everyone know the process of die casting. I hope you can pay more attention to Longhua Die Casting Machine and bring you more information.
