The design uses two mold cavity, type of the sprue is latent gate, the parting surface is chosen in the maximum section of the plastics. After plastics are molded， molding products are driven by putting from dynamic model,then using reset stem returned. In the design ,the size of the plastic parts needed to calculate ,then determine the size precision and select the type of injection moulding machine. Checking the parameters of injection machine, including the thickness of mold closing,the size of mould installation,the trip of opening mold ,the clamping force of injection machine,and so on. Determining the model of injection machine after each parameter are meet the requirements. Finally use the UG software to mill out molding parts. In the design process , in order to express the internal structure of mould clearly，there have a lot of mould structure and mould local charts ，then through CAD and Pro/E software plot its 2d, 3d stereo.
