Abstract

An integrally-formed shoe sole article with dual density comprises a first density portion and a second density portion, and one part of the second density portion covers the first density portion. The first density portion comprises a first top face, a first bottom face and an arc-shape connecting face. The first bottom face is parallel and opposite to the first top face, and the arc-shaped connecting face extends from the periphery of the first top face to the periphery of the first bottom face. A first groove for containing the first density portion is formed in the second density portion. The groove comprises a groove opening, a groove bottom located under the groove opening, and an arc-shaped wall face, the groove opening extends to the groove bottom to form the arc-shaped wall face, and the outer wall of the arc-shaped connecting face is covered with the arc-shaped wall face. A manufacturing method and mold of the integrally-formed shoe sole article are further included. The defects that when the density of the material of an inner container is reduced, a shoe sole is soft, and cannot resist tearing or bear torque generated during walking can be effectively overcome, and therefore the wearing and walking comfort for a user is greatly and perfectly improved on the premise of guaranteeing that the intensity of shoes is not influenced.

Description

technical field [0001] The present invention relates to a shoe sole object with double density, and especially relates to a shoe sole object with double density (outer shell hardness 75-80C degree, specific gravity 1.06, internal hardness degree 20C degree, specific gravity 0.24) which is integrally formed (different from the combined molding of rinsing glue) and its method of manufacture. Background technique [0002] Conventional sole article structures are layered structures that include a resilient midsole formed of polymer foam, an outsole for contacting the ground, and a support sheet at the waist of the sole. The outsole not only has the function of wear resistance, but also provides anti-skid and traction functions. The midsole is the main sole structural component, which not only provides relief from ground reaction force but also controls foot movement. Polymer foams commonly used in midsoles include ethylene vinyl acetate (EVA) or polyurethane (PU), which elastic...
