  • Patent number: 11623384
    Abstract: A rubber sole thermo-molding machine includes a lower mold seat disposed on a hydraulic actuator of the machine seat. The lower mold seat ascends and descends with respect to the upper mold seat according to the hydraulic actuator, allowing the lower upper molds to close and open. The upper mold seat moves between a normal position and a tilt position according to the turning mechanism. The middle plate horizontally moves between the upper and the lower mold seats, and has a push mechanism connected with the middle frame. When the pin of the middle frame and the fasten unit on the push mechanism are separated, the middle frame is stacked on the middle plate or the lower mold to move, facilitating the cleansing and material-feeding operations. The user can cleanse the upper mold without being hindered by the middle frame, assuring the safe and smooth process.
