Injection mould design for Camera shell
Abstract: The graduation project on the brochures of the main camera shell for the die design process. It designed plastic mold through the plastic parts of the process analysis. Due to the high quality requirements of the camera and the panel surface irregular surfaces, it required more in the cavities of the core manufacturing processes, especially polished surface roughness Ra0.2. Another point is the choice of the gate,.Because of the camera panel surface quality requirements, it could not use the outer surface of the gate, and only could use the submarine gate, setting the gate injection molding on the inner surface of the camera. In the mold design section, the focus point for the design side is pumping mechanism design, you need to set the outer side of the side of the two side sliders pumping molding. There are many problems encountered in the design, all would be solved in the course of all the solutions. The graduation project combines the expertise of four years of college which have learned to further consolidate the knowledge of mold design and related accumulated design ideas and experience.
