Introduction to dimensional accuracy and finish of aluminum die casting die
(Summary description)Aluminum die-casting dies have high dimensional accuracy and surface finish, and are relatively stable under certain conditions, with interchangeability. Therefore, many aluminum die-casting molds can be assembled in machines and equipment without cutting or only a small amount of processing on some parts. During design, it is necessary to understand the accuracy and smoothness that can be achieved by the aluminum die-casting die under certain production conditions, so as to be one of the bases for selecting the aluminum die-casting die. If the aluminum die-casting die is selected in the design, and the requirements for its precision and finish are too high, it can only be achieved through a large number of cutting, and the result is unreasonable in technology and economy. At present, there is no unified standard for the dimensional accuracy and surface finish of aluminum die-casting dies. Generally speaking, the dimensional accuracy of aluminum die-casting die is about 3-4 levels lower than that of die-casting die. The accuracy of die-casting die is usually level 3-4 (sometimes up to level 2) (according to the accuracy level of gb159-59), so the dimensional accuracy of aluminum die-casting die is within the range of level 6-8. The finish of aluminum die-casting die is about two levels lower than that of die-casting die cavity surface, generally 5-6 levels. When the mold is just used, it can reach grade 7-8 (according to gb1031-68). The precision and finish of aluminum die-casting die depend on casting structure, die-casting die structure and manufacturing quality. The stability of precision and finish is mainly related to the service life (die-casting times) of die-casting die, process factors, operation specifications, etc. For example, the surface finish of aluminum die-casting die decreases significantly with the increase of die casting times.
