Guardrail pouring forming formwork and method for cooperative operation of inner formwork and outer formwork

The invention discloses a guardrail pouring forming template with an inner mold and an outer mold cooperatively operated. The guardrail pouring forming template comprises an inner mold template, an outer mold machine and the inner mold template, wherein the inner mold template comprises a left inner mold, a right inner mold, an inner mold removing device and a longitudinal connecting device; and the outer mold machine comprises a left side outer mold, a right side outer mold, a driving walking module, a driven walking module and an outer mold dismantling module. According to the device, when the outer mold dismantling module and the inner mold dismantling device needing to be dismantled are located on the plane, the working screws are rotated to extend downwards, the working screws are inserted into inner cavities of the threaded holes, the first connecting rods and the second connecting rods are separated from each other along with rotation of the working screws, and therefore the distance between the first
