Do you know how to maintain a die casting mold?
Die casting mold belongs to the process of casting liquid die casting parts, is a special die casting die forging machine. For die casting, die casting material, die casting machine and die three elements are essential.
Die casting diebelongs to the process of casting liquid die castings, and is a special die casting die forging machine. For die-casting, die-casting materials, die-casting machines and molds are three essential elements. In order to improve the production efficiency, brand quality and higher economic benefits in the production process, and use the die casting mold to extend its service life, the maintenance of the die casting mold is very important< br>
1. Try to reduce the quenching and heating of the mold, and try to produce continuously. Under the cold mold state, it is strictly prohibited to press and shoot at high speed
In the process of die casting, the die casting die is always in the reciprocating fatigue state of thermal expansion and contraction. The temperature of the cavity basically varies from 160 ° C to 350 ° C. The mold is rapidly cooled and heated, and continuous thermal expansion and contraction cause mold shrinkage, which increases mold fatigue accordingly. When the production starts in the cold mold state, the mold temperature starts to rise from the low temperature, the temperature difference increases, and the expansion and contraction of the mold increase. The fatigue degree of the die increases accordingly, which will accelerate die damage and shorten die life. Therefore, in die casting production, continuous production should be tried as far as possible to reduce the rapid cooling and heating of the die, so as to extend the life of the die< br> In addition, in the cold mold state, the temperature during normal production cannot be reached, and the gap between mold parts is large. In this case, it is strictly forbidden to open high-speed injection and pressurization. Otherwise, the clearance part of the mold will easily enter the aluminum sheet, thus damaging the mold and affecting the service life of the mold< br> 2.
