Shoe article, method and apparatus for manufacturing the same

A method for manufacturing a shoe article, comprising:

• a material preparing step comprising:
• providing a shoe-shaped knitted object having a shoe bottom face facing upward;
• providing a frame comprising:
• a middle frame being arranged above the shoe-shaped knitted object and comprising a frame supporting surface facing the shoe bottom face and a plurality of middle frame holes formed in the frame supporting surface, the frame supporting surface abutted against the shoe bottom face, so that one end of each middle frame hole close to the shoe-shaped knitted object being closed by the shoe bottom face to form a plurality of cavities;
• and
• a convex column module being arranged above the middle frame and comprising a plurality of convex columns, each convex column corresponding to one of the middle frame holes, the height of each convex column being smaller than the depth of the corresponding middle frame hole, and the convex column module being movable relative to the middle frame, so that the convex columns respectively extending into or leaving the corresponding middle frame holes;
• and
• filling particles of a foam material in the cavities;
• a heat pressing step comprising simultaneously carrying out the following steps after the material preparing step:
• heating at least one of the frame and the shoe-shaped knitted object to make the particles of the foam material become a semi-solid state foam material;
• and
• applying a force to at least one of the convex column module and the shoe-shaped knitted object to approach the other, so that the convex column being close to the shoe bottom face;
• a cooling step comprising cooling the frame and the shoe-shaped knitted object after the heat pressing step to solidify the semi-solid state foam material to form the plurality of foam structures connected with the shoe bottom face in positions corresponding to the cavities on the shoe bottom face, the foam structures being separated from each other;
• and
• a separating step comprising applying a force to at least one of the frame and the shoe-shaped knitted object to move away from the other, and making the foam structures and the shoe-shaped knitted object separate from the frame together.
