Figure 2 As shown, when using a traditional mold to arrange the material strip 200', the following problems exist: 1. Due to the limitation of the molding structure of the four sides 101 of the product 100, only the middle single-sided strip 201' can be set, and the feeding stability is poor, which is prone to problems. 2. The middle strip leads to an increase in the step distance, resulting in material waste, the mold needs to be lengthened, and the tonnage of the stamping equipment becomes larger. 3. The peripheral cutting is hollow, the material strip has no strength, and the material width needs to be increased, resulting in material waste. 4. Molding and trimming require two steps, which causes the mold to become longer, the mold cost increases, and the tonnage of the stamping equipment becomes larger. Utility Model Content
