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 need to calculate the size design, determine the size precision, the preliminary selection and the injection machine. And the injection molding machine of gating system, forming part of the structure, forming part of the size, mold release mechanism, exhaust system, temperature control system design and calculation. And to check the injection machine parameters, including the thickness of mold closing, mold installation size, mold opening stroke, the clamping force injection molding machine etc.. All the parameters meet the requirements to determine the type of injection machine. In the design process, in order to express more clearly the internal structure of the mold, so a moving die insert, fixed die insert, the fixed mould push plate 2D part drawing and 3D map explosion.
