Inject mold Design of Block body
Abstract: The graduation project on the brochures of the main mobile phone back for the die design process. The plastic parts of the process, the design of a two-mode point of the plastic mold. First of all, this paper a brief introduction of the mold design and classification, and then the product was introduced by the material properties, and the initial choice of injection machine. This statement has also described in detail the structure of the program die, including the identification of sub-surface, forming the structural design of parts and components, core-pulling mechanism , Stripping agencies Die-oriented institutions, and so on the cooling system design process. There is still an important part of the process parameters of choice and calculation. Check with the injection mold injection machines, such as the relationship. This design is through the use of UG and AutoCAD completion of the assembly, parts map. The integrated design of a university graduate in three years the school's expertise to further consolidate the mold design-related knowledge, and the accumulation of related design ideas and experience.
Key words: Block body; hydraulic drawing-core; injection mould
