This design is the micro password shell plastic mold design and analysis of parts structure technology, adopt ABS as the material of plastic parts. With double parting surface, according to the mold cavity number, and the maximum injection volume, injection pressure and clamping force, the installation of the mould size factors such as the injection machine choice, choose the size of the molding parts; Use two plate mold small mold, latent type gate; USES the straight guide pillar guidance, oblique bumps, complete side smoke and ejection, parting, and the selection is made to the mold material, such a structure are designed, which can ensure the mold reliable operation. On the mold structure and injection machine matching check. Finally using UG to map the mold 3 d graphics and AutoCAD drawing a set of mold assembly drawing and part drawing.
