Abstract

The rapid development of the plastics industry, put forward the good quality, high manufacturing precision, short development cycle, higher and higher requirements of injection mold design and production, can adapt to this demand has become the key factor in the development of mold manufacturing enterprises. Mould technology is a comprehensive subject integration of mechanical engineering, computer application, automatic control, numerical control technology and other disciplines as a whole.
This paper aimed at Samsung mobile phone back cover injection mold making a reasonable design structure, including molding parts and components design, gating system design, demould mechanism design, cooling system design. According to the analysis, a set of plastic injection mold design, the mold and the main parts of the CAD drawing.
