Design of injection mold for dome camera shell
Abstract：injection molding is the main method of forming thermoplastic parts, so a wide range of applications. The plastic injection molding is the raw material into the barrel through the heating and melting, making the high viscosity of the fluid, the plunger or screw as pressure tool, cavity melt through the nozzle into the higher pressure in the mold, after cooling, the solidification stage, and then ejected from the mould, a plastic products. Based on the plastic dome camera shell as the object, the injection mold design process is introduced in detail. The main use of UG and AUTOCAD in the software design, three-dimensional modeling of parts according to the parts of the parts diagram, and based on Formability Analysis for the model, the calculation and structure design of the necessary. The injection mold wizard, improve the efficiency of design. Finally completes the creation of engineering drawing by Autocad, and combining with the calculation process and the design of sorting out the mold design specification.
