Molding Process Analysis and Inject Design of Sterilizer Holder
Abstract: Injection molding is the main method of molding thermoplastic parts, this graduation project to disinfect pot support for the object, described in detail the process of injection mold design of plastic parts. Paper, bottle sterilizer parts of plastic raw materials selection and point the way pouring gate detail. The main use of UG design software respectively different three-dimensional structure of plastic parts, injection molding some parts, injection system, the release mechanism, and so the simulation design and analysis. Finally, determine selection and verification, parting injection molding machine model, cavity design, molding some parts of the design, gating system, cooling system, exhaust overflow bleed air system, the design of the release mechanism, reset the system design and other design components. Finalize the drawings produced by Autocad, and summarized the correlation calculation instructions.
Key words: sterilization pot holder; design of molding ; injection mold; point gate
