【Abstract】:  The project's name is the design of oil filler bracket piercing and blanking die. This design is mainly about two aspects, namely sheet metal forming technology and punch die design. It  analyses and interprets the development of mold,as well as explains the contents of this project; The main body of the technological design is about the analysis of  parts and the selection method of mold;  Becides it concerns the mold design and the design and selection of rubber;moreover it is about the determination of every parts' sizes and analysis of the improvement of mold; finally it summarizes the process of this design.’
    key words: mold, mold selection,  rubber,  technological design,  mold improvement
