Characteristics of die casting process

The dies used in die casting are usually machined from alloy materials that are more strength than those being machined. This process is somewhat similar to injection molding. Casting equipment and mold costs are generally relatively high, so it is not suitable for processing small quantities of parts. However, as the die casting method is relatively simple, only four main steps are needed, and the incremental cost of individual costs is very low, so it is very suitable for the manufacture of large quantities of parts and components. In addition, die casting is much more flat than other casting techniques and has higher dimensional consistency, so die casting is the most widely used in all casting processes.

General features of die parts design

In the die design output, three-dimensional modeling is used to describe the structure of the die and the basis of NC machining, and the two-dimensional drawing is the basis for the processing design of the part. Therefore, the design of mold parts requires the output of two-dimensional drawings of mold parts. The processing design of the mould parts not only conforms to the general features of the machining process design, but also must be flexibly adjusted according to the special requirements of the machine. Its general features include several aspects:

Identification and determination of reference

The design criteria of die parts include two aspects: parts, reference and machining reference. The parts datum describes the assembly surface of the parts, and the machining standards should coincide with the parts datum.
