Description

Technical Field

[0001] The utility model relates to the field of molds, in particular to a vulcanization mold for lightning arresters without label marking. Background Art

[0002] There are two commonly used nameplates for lightning arresters in the current market. One is to cover the upper end of the high-voltage terminal of the lightning arrester with an aluminum sheet about 1mm - 2mm thick, and then use a laser marking machine to mark the equipment parameter information required by the national standard GB / T 11032-2020 of the lightning arrester on the surface of the aluminum sheet. The other is to buckle a stainless steel cover on the upper end of the high-voltage terminal of the lightning arrester, and also use a laser marking machine to mark the equipment parameter information required by the national standard GB / T 11032-2020 of the lightning arrester on the surface of the stainless steel cover. The above two commonly used nameplate marking methods will increase the material cost, waste labor, and with manual operation, it is easy to have phenomena such as wrong marking and missing marking of nameplate information, which will cause great losses to the product quality and the company's reputation. Therefore, a vulcanization mold for lightning arresters without label marking is proposed to solve the above technical problems. Content of the Utility Model
