Pouring mold suitable for frame track plate inner convex blocking table and using method of pouring mold

The invention discloses a pouring mold suitable for an inward-convex blocking table of a frame track plate and a using method of the pouring mold, and belongs to the technical field of ballastless track maintenance construction. At least two splicing units and corresponding connecting assemblies are arranged, and transverse supporting rib plates on the splicing units and connecting rods and connecting pieces in the connecting assemblies are correspondingly arranged; a rounded rectangular frame structure can be rapidly formed, then a pouring mold of a convex blocking table is formed in a middle hollow area of a frame track plate, and pouring of the convex blocking table in the middle hollow area of the frame track plate is rapidly completed. The pouring mold is simple in structure and convenient to assemble, the limiting problem caused by damage of convex blocking tables at the two ends of a frame track plate can be rapidly solved, the stability and durability of the frame track plate and a ballastless track a
