Abstract
Business, so the overall performance analysis process of this graduation design mainly is the study of cap type plastic parts forming process, the main contents include cap type parts, mold structure design, injection machine type selection and process parameters are identified and pushing mechanism design. Because the parts and plastic parts by injection molding in the injection molding process, gating system settings is critical. Therefore each parameter choice are very cautious, but also consider the overflow and leakage problems, so in the forming process of sealing requirements are particularly high, in order to prevent injury to the operating personnel. Design of data selection and technical reference are from refs Examination literature.Through this design, to mold with a deeper understanding and attention to some of the details of the design, to understand the structure and working principle of mold. Through the study of UG, a relatively simple parts of parts library, so as to effectively improve work efficiency; by drawing the assembly drawing, part drawing, further deepening the CAD proficiency, deepen the understanding of the various parts of mold.Through the graduation design process, know a lot of problems and know many do not understand their own professional knowledge, met many difficulties, in problems, and to learn to problem solve. Design of the entire graduation is not only a summary of the graduation, is of a task you will accept training and ability test, in order to gradually improve to solve their own problems, problem analysis and the comprehensive ability.
