This invention discloses a heel shaping machine for protective shoe production, relating to the technical field of shoe material processing equipment. It includes a frame, a support base, a heel, a shaping mold, and a clamping base. The invention employs a clamping cylinder-driven linkage mechanism to control a pressure plate to rotate obliquely downwards to clamp the protective shoe heel blank. During the rotation process, the pressure plate applies not only an inward clamping force to the protective shoe heel blank but also a downward pulling force, ensuring the heel blank is fully stretched and conforms to the heel surface. This prevents the protective shoe heel blank from accumulating or wrinkling in areas with large curvature, or forming uneven creases at seams, thus effectively improving the shaping quality of the protective shoe heel.
