Die casting molds are usually made of alloy materials with higher strength than the processed parts. This process is somewhat similar to injection molding. The cost of casting equipment and molds is generally high, so they are not suitable for processing small batch parts. However, due to the relatively simple processing of parts by die-casting method, generally only four main steps are required, and the single cost increment is very low, so it is very suitable for the manufacturing of large quantities of parts. In addition, die casting has a smoother surface and higher dimensional consistency than other casting technologies. Therefore, die casting is widely used in all casting processes.

General features of die part design

In the mold design output, 3D modeling is used to describe the mold structure and as the basis of NC machining, while 2D drawing is the basis for part machining process design. Therefore, the design of mold parts requires the output of two-dimensional drawings of mold parts. The machining process design of mold parts not only conforms to the general characteristics of machining process design, but also must make flexible adjustment according to its own special requirements. Its general features include the following aspects:

Identification and determination of benchmarks

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