Introduction to the Content and Characteristics of Die Casting Mold Parts Processing DesignIssuing time:2021-09-27 17:51 The molds used in die-casting processing are usually made of alloy materials with higher strength than the parts being processed, which is somewhat similar to injection molding. The cost of casting equipment and molds is generally high, so they are not suitable for processing small batches of components. However, due to the relatively simple use of die-casting methods to process parts, generally only four main steps are required, and the cost increment of a single item is very low, making it very suitable for the manufacturing of large quantities of parts. In addition, die casting produces a smoother surface and higher dimensional consistency compared to other casting techniques, making it widely used among all casting processes. General characteristics of mold part design In mold design output, 3D modeling is used to describe the mold structure and serve as the basis for CNC machining, while 2D drawings are the basis for part processing technology design. Therefore, the design of mold parts requires the output of two-dimensional drawings of the mold parts. The design of mold parts processing technology not only conforms to the general characteristics of mechanical processing technology design, but also must be flexibly adjusted according to its own special requirements. Its general features include the following aspects: Identification and determination of benchmarks The design criteria for mold parts include two aspects: part criteria and machining criteria. The part reference describes the assembly surface of the part, while the machining reference should generally coincide with the part reference. |
