Description

Technical Field

[0001] The utility model belongs to the technical field of welding molds, in particular to an anti-stripping welding mold for lightning protection construction. Background Art

[0002] The welding mold is also called the exothermic welding mold. The exothermic welding mold is made of high-purity graphite and is used for the welding head molding of grounded exothermic welding. A complete mold consists of a mold body, a top cover, and a hinge. The combination of different materials is completed through the feed ports at different angles. Finally, welding is performed by adding welding powder and ignition powder. The welding mold needs to be connected externally to provide a stable clamping effect during the welding process, otherwise demoulding is likely to occur, which will cause welding failure.

[0003] However, the existing equipment has poor closure during use, which can easily lead to leaks during welding, resulting in poor welding of the equipment. At the same time, it is cumbersome to install the mold, inconvenient for personnel to use, and very time-consuming and labor-intensive. Therefore, we proposed an anti-demolding welding mold for lightning protection construction. Utility Model Content
