Introduction to the Contents and Characteristics of Die Casting Die Parts Processing Design

Characteristics of Die Casting Technology

Die-casting moulds are usually made of alloy materials with higher strength than the parts being processed. This process is somewhat similar to injection moulding. Casting equipment and moulds are generally expensive, so they are not suitable for processing small batches of parts. However, because the die-casting process is relatively simple, generally only four main steps are needed, and the single cost increment is very low, so it is very suitable for the manufacture of large-scale parts. In addition, die casting is widely used in all casting processes because of its smoother surface and higher dimensional consistency than other casting technologies.

General Characteristics of Die Parts Design

In the output of die design, three-dimensional modeling is used to describe the die structure and as the basis for NC machining, while two-dimensional drawings are the basis for part processing technology design. Therefore, the design of die parts requires the output of two-dimensional drawings of die parts. The process design of die parts not only conforms to the general characteristics of mechanical process design, but also needs to make flexible adjustments according to its own special requirements. Its general features include the following aspects:

Identification and determination of benchmarks

The design benchmark of die parts includes two aspects: part benchmark and processing benchmark. The part datum describes the assembly surface of the part, and the processing datum should generally coincide with the part datum.
