The invention provides a method for processing a fixing ring of a refrigerator temperature controller, which has the advantages of capability of continuously processing, continuous forming, high efficiency and good safety, and accordingly, the invention also provides a special mould for processing the fixing ring of the refrigerator temperature controller. The method is characterized by comprising the following steps of: blanking, punching a guide hole, punching a side hole, deburring, upwards flanging, semi-shearing (1), semi-shearing (2), blanking (1) and blanking (2). The special mould comprises an upper mould structure and a lower mould structure, wherein the upper mould structure is assembled with the lower mould structure through the guiding of an inner guide pole and an outer guidepole. The special mould is characterized in that the upper mould structure and the lower mould structure are sequentially provided with corresponding punching devices, deburring devices, upwards flanging devices, semi-shearing devices and cutting-off blanking devices along the conveying direction of the materials.
