Abstract:This article design an injection mold to manufacture the shell on a thumb stapler. This article begins with the significance of the topics described, then the appearance of the shell on a thumb stapler observation and size measurement, material selection, the choice of the injection molding machine and the back of the mold design.

　　　The first chapter introduces the purpose and significance of the topics of this design, described the development of the injection mold, then talked about the profile and background of the plastic mold industry in China, the last idea of the development trend of the injection mold.

　　　The second chapter is part of the design of the mold the physical components and data check. Reasonable material, selected based on the observation and measurement of thumb stapler adapted to injection molding machine, and its related data checking, and then design the layout of the mold cavity and parting surface.

　　　The third chapter is by UG design visualization, this chapter can be more intuitive understanding of the design.

　　　The fourth chapter is to show some of the results of the design, equipped with three-dimensional map, part three maps.

　　　Chapter V, the final chapter, this chapter is conclusive on the design, including design inadequacies and some useful points.
