The first design of the technological characteristics of the printer side of the cover, the design process is introduced in this paper, the printer side cover injection mold design and mold. Focusing on the process characteristics analysis of structure design and the printer side printer side cover cover. The use of a mold cavity, sprue, two plate mold, mold design and the process characteristics of plastic parts include mold cavity number, the selection of injection molding machine, mold design process of parting surface, gating system, cooling system, parting mechanism etc.. Also on the injection mold parts size calculation, and introduces the main parts processing and assembly process of die. The mould is compact in structure, reliable work, convenient operation, high production efficiency.
