The graduation project title is the camera bracket a parts injection mold design, this text discussed primarily the plastics injects the basic principle of the mold with design the process, combining to emphasize to relate the Chargers shell inject the design process of the mold. First, related the function of the molding tool with domestic and international development condition and its development directions. Then discussed the choice of the project with certain. Returns a project for making sure give a detailed design process with compute process; very much again the molding tool to design to preceded the economic viability assessment. Keywords The piercing ,bending and blanking Composite mold Inject the mold Take out core Inclined slippery piece 目 录 摘要……………………………………………………………………………Ⅰ Abstract…………………………………………………
