The principle of die casting
The principle of the cold die casting is to use high pressure to press molten metal into the cavity of a precision mold at a high speed. In cold die casting, the molten metal is poured into the press chamber by a manual chamber or an automatic pouring device, and then the injection punch advances to hydraulically press the metal into the cavity of the mold. After the molten metal is opened, the product is formed, the die-casting mold is opened, and the casting is taken out to complete. A die casting cycle.
Die-casting mold is one of the three major links of die-casting production. A reasonable structure is a prerequisite for smooth die-casting production and an important role in ensuring the quality of castings (the pass rate).
What materials are generally used for die-casting molds？
Die-casting molds generally use hot-worked mold steel H13, SKD61, 8407, and 8417.The fundamental and effective way to avoid premature cracking of aluminum die-casting molds is to increase the mold rigidity concentration and lower the melting point. Improve the high temperature mold performance of the mold, thereby improving the anti-cracking performance. On this basis, make the appearance ratio of the mold steel and mold, cooperate with the heat treatment process, and use and repair the mold. Extend the service life of the mold.
