【正文】 h tube, elastic ponents, but the quality is poor, the small scale of varieties. These products not only domestic supporting a lot of demand, is also very good export prospects, should continue to vigorously develop. Nitrogen cylinder and hot runner ponents no formal professional production plants, mainly rely on imports, should raise the level on the existing basis, the formation of the standard, and organize largescale production. With the mass production and new product development is an indispensable tool. Without high levels of mold, there will be highlevel, highquality industrial products, mold importance is selfevident. Mold rapid industrial development, injection mold toward the highefficiency, lowcost development. In order to cater to this trend, in addition to the focus on finding graduate design, literature, independent design and application of knowledge, the ability to solve problems in the design process should focus on the ability to develop design software shorten the graduation design and production practice proficient. Injection mold design methods and processes. First, according to the plastic parts the UG software part model analysis of materials and process characteristics, then parting surface design, and determine the number of cavities, and then select the check of injection molding machines, injection molding machine process parameters, including injection volume, the clamping force injection pressure, close the mold thickness and the height of the injection molding machine. The finalized form Solution: gating system design, the overall structure of the design the pulling mechanism design of the cooling system design, and then use the UG software, CNC machining molded parts, to determine the tool path and processing methods to simulate the process.
