  • Publication number: 20240245171
    Abstract: A method for manufacturing a shoe article is disclosed. The method includes a material preparing step, a heat pressing step, a cooling step, and a separating step. The material preparing step includes providing a frame, filling particles of a foam material in the cavities, and providing a shoe-shaped knitted object. The frame has an upper supporting face. The upper supporting face includes at least two concave area with a plurality of cavities. The shoe-shaped knitted object includes a shoe bottom face. The heat pressing step includes simultaneously heating the particles of the foam material to become a semi-solid state foam material, and applying a force to make the shoe bottom face contact with at least a portion of the foam material. The cooling step includes solidifying the semi-solid state foam material to form at least two foam structures connected with the shoe bottom face in positions corresponding to the cavities, wherein the foam structure includes a foam layer and a plurality of foam protrusions.

  • Publication number: 20240245172
    Abstract: An automatic shoe-making device includes a bottom mold unit having a shoe last, two side mold units driven to combine with or separate from each other, a pressing mold unit driven to be movable relative to the bottom mold unit, a feeding unit configured to feed a sole material into a mold cavity in a supercritical fluid state, and a control unit configured to: control the two side mold units to form a combined configuration, so the two side mold units surround the shoe last to form the mold cavity for receiving the sole material, control the pressing mold unit to hot-press the sole material to form a shoe product or a shoe component, and control the pressing mold unit and the two side mold units to move away from the bottom mold unit to allow the shoe product or the shoe component to be removed from the shoe last.

  • Publication number: 20240246309
    Abstract: An automatic shoe-making device includes a bottom mold unit having a shoe last for selectively receiving an upper, two side mold units driven to combine with or separate from each other, a pressing mold unit driven to be movable relative to the bottom mold unit, and a control unit configured to: control the two side mold units to move toward the bottom mold unit to form a combined configuration, so the two side mold units surround the shoe last to form a mold cavity for receiving a sole material, control the pressing mold unit to hot-press the sole material to form a shoe product or a shoe component, and control the pressing mold unit and the two side mold units to move away from the bottom mold unit to allow the shoe product or the shoe component to be removed from the shoe last.

  • Publication number: 20240246310
    Abstract: A method for manufacturing a shoe article is disclosed. The method includes a material preparing step, a heat pressing step, a cooling step, and a separating step. The material preparing step includes providing a shoe-shaped knitted object having a shoe bottom face, providing a frame having a plurality of middle frame holes, and filling particles of a foam material in the middle frame holes. The heat pressing step includes simultaneously heating the particles of the foam material to become a semi-solid state foam material, and applying a force to make the foam material substantially apply pressure onto the shoe bottom face. The cooling step includes solidifying the semi-solid state foam material to form a plurality of foam structures connected with the shoe bottom face in positions corresponding to the cavities. The separating step includes making the foam structures and the shoe-shaped knitted object separate from the frame together.
