Design of injection mould for electric box

Abstract The design is based on the theory of plastic injection mold, with the knowledge of mechanical design, in the teacher's guidance to complete the electrical box injection mold design。The graduation project is the design of the electric box on the cover of the mold design, in the process of plastic parts for a comprehensive analysis, and constant comparison, the final design of a set of basically meet the requirements

of the injection mold。 The graduation design from the technology of product structure, specific mold structure of, gating system on mold, mold forming part of the structure, ejector systems, cooling systems, injection molding machine of choice and the related parameter check, there are detailed design。 In this design, we must analyze the process performance of the plastic parts, and then draw the part drawing of the parts。 Begin to select materials and select injection machine after marking the size。 After the preparation is completed, the mold is designed。 Contains design of side gate, sprue, runner design, mold cavity distribution, mold selection and verification, injection machine, such as the check, calculation part contains the maximum injection quantity check, check the clamping force of the lock etc。, the most important is to the die structure and medium cavity and core sections of radial and height, depth and the size of the calculation。 In the design process, we need to refer to the relevant information, which is the problem of continuous improvement, and finally can meet the requirements of the design。
