Title  Cab machine structural parts injection mold CAD design                     

Abstract

Injection mold of automobile cab interior structure has been designed and researched in this article. Production process and the specific structure of the structure has been analyzed. Injection mold institutions, systems, such as casting, core pulling and ejection system, forming part of the rationality and practicality，through certain design methods, principles of rational allocation and selection, at the same time, a suitable injection molding machine has been selected, and relevant design parameters above were been detailed checked and correction choiceed. Taking into account the process conditions of injection molding products, the design has been adopted as a way of producing a mold cavity, by the top of the mast, using a spring core pulling structure, its overall reasonableness meet certain requirements. With this design, the cab interior structure can be processed to produce injection-molded model to improve its productivity.
