Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a precision stamping die for a quick-install shielding cover. Background Art

[0002] Shielding covers, as metal covers used to prevent interference from external radiation and shield against external radiation interference, are widely used in a variety of fields, such as digital technology, transportation, electrical equipment, aviation and navigation, and medical supplies. Shielding covers are primarily formed in one piece through die stamping. The upper and lower dies of existing stamping molds typically require removal of the entire mold body from the stamping equipment during maintenance and installation. The molds are then disassembled layer by layer, and finally the forming mold is removed. Installation and disassembly are cumbersome, and due to the differences in mold size, larger molds are heavy and require lifting with lifting gear for maintenance, which is time-consuming and labor-intensive. Utility Model Content
