【正文】 with a light weight, easy to clean, corrosionresistant aging, high strength, long service life, making easy, low prices and so on. Through the process of plastic parts for analysis and parison, the final design of an injection mold. Process from the product structure of the project, specific mold structure starting on the casting mold system, mold forming part of the structure, the top out of the system, cooling system, the choice of injection molding machines and related parameters of the check, there are detailed design, while and simple preparation of the mold process. Through the entire design process that can be achieved in the mold plastic parts required in this process Rich source of raw materials, plastic products, low price and excellent performance characteristics. It is in puters, mobile phones, cars, motors, electrical, instrumentation, home appliances and munication products manufacturer has an irreplaceable role, the application is extremely broad. Pieces of molding thermoplastic injection molding is the main method, so a wide range of applications. Injection molding is the plastic material into the barrel through the heating and melting, making the high viscosity of the fluid pressure with a plunger or a screw as a tool to melt at a higher pressure through the nozzle into the mold cavity, after cooling, freezing stage, then emerge from the mold, a plastic products. Based on the volume and determine the process performance of plastic injection molding method using plastic parts production. The product is designed for mass production, so the design of the mold have a high Zhusu efficiency, feed system to be able to automatic ejection, in addition to ensure the quality of plastic surface using point gate, so we choose a single sub surface injection mold, points gate automatic ejection structure. Mold cavity eightcavity mold with a balanced layout, gating system using point gate forming, introduced in the form of introduction agencies to plete sixteen putting the introduction of plastic parts. As performance requirements of plastic injection molding process in the cooling system, so also in the mold design to design. The only reference to the design of a large number of paper documents, and access to information on the Internet, the design process is plete.
