Design of injection mould for NC electric box base

Abstract With the rapid progress of the plastics industry, injection mold design and manufacture will increasingly faced with more and higher requirements, for example, to ensure high quality of production, and ensure the high precision manufacturing, research and development cycle shortened, whether it can adapt to this kind of demand is now a mold manufacturing, to the healthy development of enterprises an important factor。

This topic research of NC electrical box injection mold base design。 This process includes according to the model of the product mold design of parting surface, cavity and core of determination, gating system design, analysis of filled plastics。 This topic will also involve the application of 2D and 3D software, such as AutoCAD, UG, through this design can let me know the mould structure of the injection mould design, skilled application of CAD, UG and a series of software, cultivate a comprehensive use of their own learning basic knowledge and professional based this theory, the basic method to analyze and solve the practical problems of measurement and control, and other related works。
