The Plastic Profile Extrusion Mold Cad Technology Research And Development

In this paper, based on comprehensive familiarity and mastery of Plastics profiles extrusion mold and the function modules of the SolidWorks '.' and the second developing tool it supplied. Through analysis about the process and characteristic of plastics profiles extrusion mold design, part module of a CAD system for the plastics profiles extrusion mold was developed, where VB was applied as developing tool.In addition, a parametric graphics library of standard mould base and its frequently used components and standard parts of extrusion mold was built on the platform by program. On the basis of the above work, a CAD system of plastics profiles extrusion mold was created. In all this process the constitute methods of parametric graphic library of extrusion mold, the realization of parametric drafting, the technology of object-oriented programming and the applications of database were systematically explored. A user-friendly visual special interface was customized on the basis of intrinsic interface, which accorded with the demands of mold design. At last, an actual process of the extrusion mold design for a typical plastic part was demonstrated, which show that the idea of system is feasible and it can be used expediently to satisfy the demands of mold design.
