Technical Field

[0001] The utility model relates to the technical field of mold processing, in particular to a burr-free punching mold for an armrest box. Background Art

[0002] Mold burrs, also known as flash or burrs, are the phenomenon of excess material appearing on the finished product. They usually appear at the mating points of the mold, such as the parting surface, the mating parts of the slider, and the gaps between the ejector and push rod. Mold burrs not only affect the quality and appearance of the product, but may also cause more severe mold wear and even permanent damage to the mold, resulting in the mold core being scrapped. When producing automotive armrest boxes, molds are often used for production, but burrs are often generated, reducing the quality of the armrest boxes.
