Non-flame bipartition solid crossed exothermic welding mould

The utility model relates to a non-flame bipartition solid crossed exothermic welding mould, which is characterized in that a solid crossed exothermic welding operation is carried out on pure coppers or copper-clad steel strands or single round wire in a non-flame state under the conditions that a main line and a branch line are respectively not broken in one step. A reaction cavity (9) of the mould is of a shape of a reverse cucurbit, an upper cover plate is ventilated and is communicated with an inner side air hole (5) at the top of the reaction cavity (9), and an upper cover plate air channel (10) is provided with a left semicircular arc buffering part and a right semicircular arc buffering part which are provided with a plurality of flame-disinfection bars. Air outlets (7) (8) are respectively arranged on the upper part and the side of the upper cover plate (3). According to the non-flame bipartition solid crossed exothermic welding mould disclosed by the utility model, the reaction cavity (9) is of the s
