Abstract
In recent years, the machinery industry of the national revival, many manufacturing professionals are increasingly focused on mechanical CAD/CAM technology, not only because of CAD/CAM technology to develop into a relatively mature technology, but also because of plastic products and mould design and injection molding process analysis development of 3 d is more mature, the effect of plastic mold industry is becoming more and more important.
The design process of the mould shows the design process of the mould, analyzes the technological characteristics of the mould, and introduces the forming process characteristics of ABS material. In the process of die structure design, different forming schemes are proposed and compared. At the same time, the die structure and calculation are analyzed in detail. Finally, the forming part of the mould was analyzed and the equipment was checked. The working principle of mould is introduced, and the assembly of mould is introduced briefly. In this graduation project, the 3d model of the plastic shell injection mold was designed using the high-end software Unigraphics(ug) of 3d stereo modeling. According to the size of the mold design, the corresponding mold frame was selected and installed.
