Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing technology, and in particular to an FPC punching die for rapid material cutting. Background Technology

[0002] With the diversification of circuit board applications, product designs are becoming thinner, more and more products are being shipped in continuous boards, and the cutout areas are becoming larger and the micro-connections are becoming fewer.

[0003] Current technology involves manually removing the product body after punching. Because the product body is tightly attached to the mold after punching, micro-tears and wrinkles occur at the micro-connections during the removal process. This results in the scrapping of the entire batch of products, significantly reducing the product yield. Furthermore, to minimize damage and wrinkles during removal, the removal process is slow, further reducing efficiency and impacting overall costs. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a fast FPC punching die, which includes an upper die base, a backing plate, a punch, an ejector plate, a die cavity and a lower die base arranged from top to bottom; The lower surface of the backing plate is equipped with guide posts that pass through the ejector plate, and the die has guide grooves with guide sleeves corresponding to the guide posts. The upper surface of the lower die base is equipped with a positioning pin that passes through the die cavity and the positioning pin corresponds to the positioning hole on the product. The punch is provided with a relief hole one corresponding to the positioning pin, and the ejector plate is provided with a relief hole two corresponding to the positioning pin. The lower surface of the punch is fitted with a punch that passes through the ejector plate, and the upper surface of the die is provided with a groove corresponding to the cutting edge of the punch. It also includes a take-up plate placed on the die, the product being placed on the take-up plate and the take-up plate having a clearance hole for the cutting edge of the punch to pass through; The material receiving plate has three clearance holes corresponding to the positioning pins.

[0005] The material handling plate is provided with handles on both sides to facilitate the picking up and placing of the material handling plate.

[0006] The upper surface of the material receiving plate is also provided with a ceramic layer to avoid static electricity when in contact with the product and to prevent adhesion to the product.

[0007] Through the above technical solution, in order to meet the design and quality requirements of the product, this utility model adds a material-receiving plate to the bottom of the mold. After the product is punched, the material-receiving plate is lifted directly, and the produced product will be lifted up as a whole by the material-receiving plate. Because the material-receiving plate has support and flatness, the product on it is evenly stressed when it is lifted up, which will not damage the product. This prevents the punched product from being torn when it is removed, and the material removal is faster and more convenient, resulting in higher production efficiency and better meeting the quality requirements.
