Abstract:  This lesson a molding tool for is fall to anticipate to pull to the stalk bowl deep blunt the bore turn over bore compound mold molding tool designing, among them distinguish to wait to the work zero parts of the molding tool six the parts of big zeros make the detailed design.
The main contents of designing includes to wash to cut a piece craft analysis and craft projects really settle, craft calculation, the gearing of the design, molding tool that wash to cut the molding tool and adjust etc.. Compute in the craft the part want to be to the row kind design and calculation, wash the calculation, molding tool pressure of the pressure center to really settle, convex and cave mold size and make sure the calculation that make the business trip and compute the detailed calculation in contents in etc..
Blanking the mold to want at the design part that wash to the work spare parts, position the spare parts and unload to anticipate with a spare parts, lead to spare parts conjunction with fix spare parts etc. construction the proceeding the detailed analysis design. Want to be in design process work process of understanding the molding tool with notice to choose to use standard, to reunite the construction that wash the understanding that cut the mold further have.
Keywords:  blanking die，compound die，blanking，piercing，drawing
