Description

   Manufacturing method of shoe sole with integral cushion structure and shoe mold equipment   

The invention relates to the technical field of shoe outsole die-casting molds, in particular to a method for manufacturing a shoe outsole with an air cushion structure and a shoe mold device thereof.

Generally, the manufacturing method of air cushion shoes is generally made of components such as soles, midsoles, air cushions, and uppers, and then the air cushions are placed on the soles, and then the midsoles are laid on the soles and air cushions, and then the shoes are made. The surface is bonded to the outside of the sole to form an air cushion shoe. In addition, the above-mentioned components are mainly combined by sequentially bonding together with an adhesive. Therefore, the overall manufacturing steps are cumbersome and the efficiency cannot be improved; further, if the bonding between the components is not sure, the air cushion shoes After wearing for a period of time, it is easy to be separated by torsion or water erosion.

In addition, for example, the patent case of "Shoe outsole device with air cushion function" published in the Republic of China No. I499383, the patent states as its abstract: "The present invention is a shoe outsole device with air cushion function, which includes the outsole And the air valve group, when the wearer walks, the foot will have a cycle of stepping and lifting against the sole of the shoe, so that air fills the inside of the shoe through the cycle of the foot, and the shoe has a space for accommodation, and The air valve group is also inside, and the air enters the accommodating space of the outsole of the shoe, and then the air regulating function of the air valve group allows the air to circulate back and forth in the accommodating space to achieve the stability of the foot of the wearer The effects of walking, standing for a long time, or performing heavy movements on the loaded feet, etc., achieve the purpose of the present invention, and improve the lack of conventional air cushions that are prone to wear and tear or elastic fatigue in a long time. "

However, as shown in the sixth and seventh figures of the previous patent, the shoe outsole (reference number 1 in the figure) is formed by a first air chamber (reference number 31 in the figure) and a second air chamber (reference number in the figure). 32) Cooperate with the sealing film (No. 4 in the figure) to form an air cushion structure. Although it can prevent the independent air cushion structure from being separated from the outsole due to the weak connection; however, because the shoe outsole (No. 1 in the figure) And the sealing film (key 4 in the figure) must also be separately molded and manufactured, and then used to seal and combine the first air chamber (key 31 in the figure) and the second air chamber (key 32 in the figure). The steps are complicated and lead to the disadvantage that the efficiency cannot be improved.

In addition, the structure in which the shoe outsole (reference number 1 in the figure) and the sealing film (reference number 4 in the figure) are generally bonded with an adhesive is still inevitable, and it is unavoidable to wear a section of air cushion shoes due to the inaccurate adhesion. After time, it is separated by torque or water erosion.

Therefore, how to deal with the shortcomings of the previous conventional structure because the manufacturing steps are cumbersome, leading to the disadvantages that the efficiency cannot be improved, and because of the inadequate adhesion, the air cushion shoes are worn for a period of time after being worn by the torsion effect or moisture erosion and separated. The inventors of innovation are the difficulties to be solved in this case.

The upper mold is provided with a plurality of cylindrical convex portions opposite to the cylindrical grooves, so that the cylindrical holes form the reinforcing pillars of the outsole in the air cushion groove in the upper, middle and lower mold pressing steps, and The opposite columnar grooves and columnar protrusions form an elastic column of a closed layer, and when the sealing layer closes the notch of the air cushion groove in the upper and lower die pressing step, the reinforcing pillar and the elastic column are docked and combined, and blown. After full molding is performed in the air forming step, the finished product of the shoe outsole with the reinforcing pillar is taken out during the pressure releasing mold opening step. The method for manufacturing a body-shaped shoe outsole with air cushion structure according to claim 4 or 5, wherein the shoe outsole is further combined with a breathing valve in the air hole and an air duct connecting the two air cushion grooves. A shoe mold device used in a method for manufacturing a shoe sole with an air cushion structure integrally comprises: a lower mold provided with at least one large mold cavity; an upper mold provided with a closed layer mold cavity having a relatively large bottom mold cavity; The closed-layer mold cavity is provided with an air outlet convex portion and an air outlet, and an air passage is provided inside the upper mold and communicates with the air outlet and an air duct to connect the pressurized air; a middle mold is provided with a relatively large bottom on one side A cavity convex part and two spaced grooves of the cavity are provided on the opposite side of the cavity convex part, and a molding groove is formed on the opposite side of the cavity cavity. There is an air hole forming convex part; and a micro switch for controlling the pressure air output of the air duct; wherein the lower mold is pressed against the middle mold and the upper mold is pressed against the middle mold, and the large bottom cavity of the lower mold is injected with the heating molding material A shoe outsole is formed, and the closed layer cavity of the upper mold is injected with heating molding material to form a closed layer. The shoe outsole has two air cushion grooves, an air vent groove, two partition walls, and air holes in the partition walls. When the die is pressed with the lower die, the micro switch is touched, and The sealing layer is pressed against the upper surface of the shoe outsole on the side of the air cushion groove notch, and the sealing layer closes the groove of the air cushion groove, and the micro switch controls the pressure air output of the air duct and is controlled by the air outlet of the air outlet convex part Blow into the ventilation groove and enter the air cushion groove through the air hole, so that the combined structure of the closed layer and the shoe outsole is fully abutted against the outsole mold cavity and the closed layer mold cavity and fully formed. The shoe mold equipment used in the method for manufacturing a one-piece molded shoe outsole with an air cushion structure as described in claim 7, wherein the air chamber protrusions of the middle mold, two spaced grooves are used to form two air cushion grooves of the shoe outsole, The two opposing partition walls and a vent groove located in the middle, the air hole forming convex part is used for forming air holes on the two partition walls. The shoe mold equipment used in the method for manufacturing a shoe sole with an air cushion structure as described in claim 8, wherein the air protruding protrusion of the upper mold is located at the middle of the cavity of the closed layer and opposite to the vent groove of the shoe sole. The shoe mold equipment used in the method for manufacturing a sole with air cushion structure as described in claim 7, wherein the convex part of the air chamber of the middle mold is provided with a plurality of cylindrical holes opposite to the air cushion groove, and the other middle mold A plurality of cylindrical grooves are provided with relatively cylindrical holes, and the upper mold is provided with a plurality of cylindrical protrusions with opposite cylindrical grooves. Each cylindrical hole is used to form a reinforcing pillar for the outsole in the air cushion groove, and each cylindrical shape The groove and the columnar convex portion are used to form an elastic column of a closed layer.
