AI Technical Summary
Existing aluminum-plastic film punching molds have high production efficiency during the mold closing process, but the defect rate is high, making it difficult to guarantee product quality.
The process employs a method of first closing the mold and then punching the dent. The upper drive assembly drives the punching head and the air bag punch to move down through the through hole of the upper template and enter the forming area of the concave template to complete the punching. Combined with the guiding structure of the servo connecting plate and the guide mold base, the precise forming of the aluminum-plastic film is ensured.
It improves the yield of aluminum-plastic film perforated products, avoids defects such as corner wrinkles and fishtail marks, and ensures the ideal state of product appearance and aluminum layer thickness.
