Firstly, the market foreground of the pressing mould is analyzed briefly, and the second is the simple analysis of the shell parts of the electric cooker sensors, and the production process is calculated. In this paper, the calculation of the technology of the electric cooker sensor casing, as well as the unloading force, the top force and the drawing force and so on. Also wrote in the production process of the structure of the mold, mainly the design of concave and convex die, blanking die design, drawing die design, punching die design. The paper focuses on the detailed calculation of blanking die, stretching convex mould and punching die unloading device, which also check the stress of unloading spring. Analysis and calculation of the layout and pressure center. In order to make the design clearer and CAD software to draw the mold cross-section, parts drawings and so on. The entity graph is drawn with 3d software. Keywords: Bump die; Blanking convex die; Stretch convex mold; Punching punch; Process calculation 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l
