Inject mold Design of AI high-temperature version of the display components
Abstract: This design is for a given material for ABS medium size, the general accuracy of the
AI high-temperature version of the display components for mold 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 through the calculation to determine the mold structure and size, Through continuous calculation and modification, And in guiding the teacher's careful care under the guidance and patience to constantly modify again and again, Finally sure to draw the assembly drawing and part drawing.Make sure the design of the AI high-temperature version of the display components, namely the mold with one module and two cavities sliding extraction system design scheme. Then focuses on the solution, this paper mainly includes the sliding extraction system of plastic parts and injection mold design process, key points of injection mold design of main components.
Key words: Injection mold design; ABS plastic ; Sliding extraction system
