Inject mold Design of Yue Kang Intelligent sanitary ware warm wind tunnel flap
Abstract: This design is for a given material for PP small size, the general accuracy of the for the intelligent sanitary ware warm wind tunnel flapmould design. In consideration of the economy, parts of the molding technology and complexity, and many other factors in the molding process on the basis of the analysis and calculation. It also of injection mold shaping parts, and other related parts to illustrate the selection principle and selection method. During to refer to a lot of useful information related to injection mold and leaf through all kinds of manual, And in guiding the teacher's careful care under the guidance and patience to constantly modify again and again.
Make sure the design of the ware warm wind tunnel flap, namely the mould with one module and four cavities, side core-pulling design scheme. Then focuses on the solution, this paper mainly includes the side core-pulling of plastic parts and injection mold design process, key points of injection mold design of main components.
Key words: CAD modeling; rectangular side of the gate with A four-mode
