WELDER FOR FIN OF FULL PLASTIC RADIATOR

The utility model relates to a welding fin which is used for producing full plastic radiators and welding radiator fins, mainly comprising elements of a machine body, a mould plate, a mould plate guide shaft, a heating plate, a heating plate guide shaft, an air cylinder, etc. The utility model is characterized in that two mould plates which can be relatively combined and separated horizontally are installed on the machine body. The heating plate which can be vertically lifted is arranged in the middle of the two mould plates. The mould plates and the heating plate are driven by the respective air cylinder. When the welding is conducted, two heat radiating plates which the full plastic heat radiating fins are composed of are respectively fixed on the two mould plates. The utility model has the advantages of high welding seam strength, stable quality, high welding speed, and no welding deformation. A welding bevel opening is not required, and welding materials are not required. The welding technique is easy to master.
