The application of this structure is that some limiting conditions need to be met, negative angles need to exist between the part 5 and the stamping direction, the angle between the lower side wall of the part and the vertical line needs to be greater than zero degrees and less than ninety degrees, and the lower side wall cannot have a complex shape.
The structure is commonly used in a side trimming structure of a part, and a side material pressing function is realized through movement among all parts, so that trimming work at a negative angle of the part is finished. The structure does not affect the size of the negative angle of the part and the discharging and taking of the process part. Such a side pressure structure is generally used for mold design, but the following problems are also brought about.
1. The cost is high. Costs include standard part costs of the mold, tooling costs, casting costs, and the like. Guide components are needed among all the moving components to realize the stability of movement, and the more and larger the independent moving components are, the more sliding components are needed, and the higher the purchasing cost is. The more independently moving parts, the longer the machining man-hour is required, and the higher the machining cost is. The larger the whole motion mechanism is, the larger the required space is, the larger the outline dimension of the die is, and the die cost is correspondingly increased.
2. The manufacturing cycle is lengthened. As the whole mechanism is mostly cast, the casting period is long, and the mold manufacturing period is prolonged.
3. The design and debugging difficulty is high. The number of independent moving parts is large, the set moving relation among the parts is good, an engineer is required to carefully calculate the stroke relation in the design process, and the stroke value is required to be calculated again due to rebound errors at negative angles in the debugging process.
