Abstract
In this paper, based on actual engineering needs of the completion of the locking nut fan of injection mold design. The present paper completes the injection molding design of the dressing case top according to the need of the project. To take shape, we need to use the polyethylene plastic injection, for forming a two-cavity mold. And this paper has concretely analyzed product's technology capability and determined to use the plastic technological parameter and the formation equipment. This paper also has determined the overall plan of the mold manufactures, analyzed and solved the gross structure of the mold and the concrete structure of each effective part, and has carried on some essential size calculation and the intensity examination. This paper also has carried on the analysis design of surface, gating system and the release and completed the mold engineering design, and finally carried out the design of the main parts processing technology.
