Multifunctional slipforming curb machine spring unloading device, and discloses a spring unloading device of slipforming curb machine, including sliding plate, fixed plate, rod, pin and spring, retaining pin and plate, fixed plate is fixedly connected between the two side plates; the sliding pressure plate is also arranged in between the two side plates, and above the fixed bottom plate; pull rod is in turn passes through the fixed plate and the sliding plate, the front end of the connecting rod in a retaining pin; between the sliding plate and the fixed plate is arranged at least two guide posts, each lower end of the guide post is connected on the upper side of the fixed plate, and the upper end of each guide column through the sliding plate; each pillar between the sliding plate and the fixed plate are respectively sheathed with a spring. When adjusting the length of the piston rod of the hydraulic cylinder, the amount of compression of the spring will change accordingly, thereby giving an external force to the hydraulic cylinder to help reduce the weight of the molding die pressed against the structure.
