Structural Process Analysis of Precision Plastic Mold Parts

Precision plastic mold parts have a variety of shapes and sizes. here to analyze the structure of the specific parts of the processing characteristics, the first choice to analyze the parts from which the surface composition, because the surface shape is the basic factor in the choice of processing methods. Precision plastic mold parts are made up of some basic surfaces and special surfaces. The basic surface of the inner and outer cylindrical surfaces, conical surfaces and planes, etc., the special surface mainly helical surface, involute-shaped surface and some other forming surface. For example, the outer surface of the wheel can generally be machined and ground, while the inner hole can be drilled, expanded, hinged, boring and grinding. Secondly, the surface size of the process also has an important impact, with the hole, for example, macropores and holes, deep holes and shallow holes in the process has different characteristics. Therefore, when analyzing the structure of a part, pay attention not only to the characteristics of the individual constituent surfaces of the part but also to the different combinations of these surfaces. It is these different combinations to form part structural features. For example, the inner and outer surface of the main round can be composed of the disk, ring parts, but also constitute sleeve parts. For sleeve parts, it can be either a normal sleeve or a thin sleeve with a complex shape. The different structures of precision plastic mold parts in the process often have a greater difference.
