Title CAD design of the injection mold for the cover of the cosmetic box
Abstract
The cosmetic box cover injection mold design was mainly for the improvement of a kind of widely used make-up box’ production process, mainly lied in the mold design, improving the production efficiency of the plastic products, improving the old process mode of products, accomplishing the automation. On the other hand, the cosmetic cover injection mold design content was needed to be combined with computer aided design(CAD) software, so that the mold design could keep up with the latest design trends, reduce design time and cost, the design mainly includes: analyzing the makeup pieces of plastic prouducts by computer aided design software, injection molding machine model selection and verification, design of product release system and the mold open action, the design of automatic selection and check off the condensed material, mold parting surface selection, design oriented positioning system, molding system design, the design of the cooling system, exhaust system design, fixed distance parting system design, structure design, including the main structure and function of mould diagram.
