Abstract
Mold products are precision machinery, it mainly consists of mechanical parts and bodies,such as forming working parts, parts orientation, positioning parts, supporting parts, positioning components and feed mechanism, core-pulling mechanism, introduced institutions. Mold and the corresponding forming equipment supporting the use of, may directly alter the shape of metal or non-metallic materials, size, relative position and performance, shaping the work piece for qualified.
In the first part of the document mainly describes the development of stamping die, stamping die illustrate the importance and significance of this design, and then stamping parts of the process analysis, completed a process to identify programs. The second part of the nesting parts of the design plans to complete the calculation of the utilization of the material further edge blanking process of calculation and Die Design and Calculation of the work of some of the stamping equipment to provide a basis to choose. Finally, the main components of standard design and the choice of design-based mapping tool and provide a basis for forming mold, as well as the assembly drawing to provide the basis of the size. Through the draw in front of mold design and assembly of the parts diagram Fig.
