Pot body pull expansion pressing mold

The invention discloses a pull expansion pressing mold. The pull expansion pressing mold comprises an upper mold and a lower mold; the upper mold is provided with an edge pressing ring and a pull expansion wedge; the edge pressing ring is connected with a pressing rod, and is mounted on the lower side of an upper template; the pull expansion wedge is mounted on the lower side of the upper template; the lower end of the pull expansion wedge is wedged; a mold core is mounted on the upper side of a lower template; and a pull expansion slide block is arranged on a first slide rail at the top of the mold core, and is corresponding to the pull expansion wedge in position. The pull expansion pressing mold combines pressing and pull expansion procedures on one mold, reduces annealing and polishing procedures, reduces the machining cost, eliminates the annealing potential safety hazards, and meanwhile, reduces the labor intensity of staff; and the pressing and pull expansion procedures are combined, so that such problems as asymmetric heights, different sizes or even cracking of openings caused by secondary positioning errors of two procedures are prevented, the product quality is more stable, and the product quality is improved.
