Abstract：In this paper, the injection molding of laptop battery cover as the object of study, the notebook battery plastic parts of the injection mold design and manufacturing technology in two parts of a more systematic study. As the plastic parts for the shell, so the product quality, dimensional accuracy and production efficiency requirements are extremely strict. This article first on the laptop battery cover this plastic products for a detailed analysis, including the structural analysis of plastic parts, select the molding material analysis, material injection molding process analysis. Second, determine the appropriate injection molding process parameters, select the model for the HTF86X plastic injection machine, and the injection machine to check the various parameters, specifically the maximum injection volume, clamping force, mold opening and installation dimensions. And then the design part of the injection mold, including the structural design of the molded parts, the design of the gating system such as the main channel, the persion channel, the gate and the cold material, the design of the cooling system, the design of the stripping mechanism, the design of the exhaust system , Lateral core pulling mechanism design, mold-oriented mechanism design and the selection of standard mold base. Finally, part of the mold parts of the manufacturing process and mold assembly.
