The invention provides a molding press of an improved ironing device. Aiming at the drape problem caused by deformation of a traditional molding press in the film winding process, the invention provides the molding press of the improved ironing device. The molding press of the improved ironing device comprises an unwinding device, a first-plate mold pressing device, a second-plate mold pressing device, a water cooling traction and ironing device, a winding device and the like, wherein the water cooling traction and ironing device comprises a machine body, a first pressing roller, a traction cooling roller, a second pressing roller and an ironing and heating roller; the ironing device is improved as the water cooling traction and ironing device, so that the film transformation is prevented,films cannot deform and cannot generate drapes in the film winding process, and the product quality is improved; and meanwhile, guide rollers in the device are arranged according to a corresponding position ratio, and are synchronously added with guide plates, so that the films move according to fixed trajectories in equipment operation, and production is smoother.
