Plastic is one kind of new engineerig material. With its rapid development, plastic processing and molding technology have been getting more and more important, and plastics injection molding is the most commom way for polymer processing.
From "mirrors covered" two plate injection mold the structural design, manufacturing process proceed the fabrication technology begin, has carried on the analysis to the sampan type note mold's modular design, to die making's structure technology capability(manufacture feasibility, efficiency) has carried on the analysis. Introduced emphatically the sampan type note mold's unique feature and the design main point, simultaneously, from die making's structure craft aspect, introduced raised, the lower die localization processing, decides the stool and the exhausted yard lumber gathers a processing, the plunger spot to go against the pole hole the manufacture processing, as well as manufacture main points and so on other spot manufacture processing.
Based on the analysis of the application requirement and the structural features of two plastic parts,mould structure feature and die movement theory was introduced for mould with two same parts forming at one time.Feasibility of angle-pin moving side-core slide with angled-lift for inner outer side-core slides was studied and analyzed.The design process of mold was presented in detail.Idea of manufacturing two same parts in one mould was achieved.It is concluded that the mould is easy to manufact.
Key words: 2-plate injection mold; moving die; slide; fixed die; side-core pulling mechanism
