The design process of injection mould is introduced in this paper.In the design, UG and other different software are used for simulation design and analysis of the 3d structure of plastic parts, parts of injection molding parts, pouring system and stripping mechanism.Finally has carried on the selection of injection machine, and the design of the check, the determination of parting surface, cavity, the design of the core-pulling mechanism, the design of molding parts, gating system, cooling system, excessive bleed air system and demoulding mechanism design, reset the design of the system design and other components.Finally, the engineering drawing is completed by Autocad and the relevant calculation instructions are summarized.
