Please refer to fig. 7, fig. 8 and fig. 9, which are a flowchart of a manufacturing method of a shock-absorbing insole, a process diagram of the manufacturing method, and a top view of a mold according to an embodiment of the present invention. The manufacturing method of the shock-absorbing insole is used for manufacturing the shock-absorbing insole in all the embodiments. The specific structure of the shock-absorbing insole refers to the above embodiments. The manufacturing method specifically includes the following steps.

Step S102, providing a mold. The mold 90 includes a bottom mold 91 and a cover mold 92. The bottom mold 91 is provided with a groove 910, the groove 910 includes a rear end 911 and a front end 912, and the depth of the rear end 911 is greater than that of the front end 912.

And step S104, placing the damping air bag at the rear end of the groove. Wherein a gap exists between the shock-absorbing bladder 20 and the wall of the groove 910. The rear end 911 of the groove 910 is provided with bumps 913, and the number of the bumps 913 is the same as that of the second position-limiting holes 240. That is, the rear end 911 is provided with at least two bumps 913. In the present embodiment, the rear end 911 of the groove 910 is provided with two bumps 913. The lower end surface 24 of the cushion bladder 20 is placed into the rear end 911 toward the bottom of the groove 910. The two protrusions 913 are respectively clamped in the two second limiting holes 240 of the airbag 20, so that a gap exists between the airbag 20 and the wall of the groove. The lower end surface 24 of the shock-absorbing air bag 20 is further provided with a limiting groove 241, and the second limiting hole 240 is arranged in the limiting groove 241. The rear end 911 of the groove 910 is correspondingly provided with a protruding edge 914, and when the shock absorbing airbag 20 is placed in the groove 910, the protruding edge 914 is clamped in the limiting groove 241 to limit the shock absorbing airbag 20 in the groove 910.

Step S106, filling the liquid molding material into the groove. Because there is a gap between the damping bladder 20 and the wall of the groove, the liquid molding material will wrap the damping bladder 20 when the liquid molding material is filled into the groove 910. And, the liquid molding material can also flow into the second stopper hole 240 through the opening 220 of the reinforcement part 22.

And step S108, covering the cover mold on the bottom mold to seal the groove. In this embodiment, a stop block 920 is convexly disposed on one side of the cover mold 92 facing the groove 91, and the shape of the stop block 920 is matched with the shape of the groove 910. When the cover mold 92 is seated on the bottom mold 91, the cover mold 92 seals the groove 910. The limiting block 920 is accommodated in the groove 910, and a closed cavity is formed between the limiting block 920 and the groove 910. The liquid molding material and the damping air bag 20 are accommodated in the closed cavity, and the liquid molding material fills the closed cavity.

Step S110, the mould is heated, so that the liquid molding material is solidified to form the shock-absorbing insole. In this embodiment, the liquid molding material is a heat-curable material. That is, the liquid molding material solidifies when heated. The bottom mold 91 is provided with a heating pipe (not shown), and heat generated from the heating pipe can be conducted to the cover mold 92 through the bottom mold 91. That is, the heat generated by the heating pipe can act on the liquid molding material in the closed cavity through the groove wall of the groove 910 and the cover mold 92, so that the liquid molding material is solidified. After solidification of the liquid molding material, the rear end portion 11 of the body 10 is formed at the rear end 911 of the recess 910, and the front end portion 12 of the body 10 is formed at the front end 912 of the recess 910. The convex edge 914 and the convex block 913 form lines corresponding to the limiting groove 241 and the second limiting hole 240 on one side of the shock absorption insole close to the lower end surface 24. The stopper 920 forms a recess 70 (shown in fig. 4) corresponding to the stopper 920 on a side of the shock absorbing insole near the upper end surface 23.

Before step S104 is performed, the manufacturing method further includes the following steps.

Step S103, injecting the liquid molding material into the groove, so that the bottom of the groove is completely covered with a layer of the liquid molding material. Before the shock-absorbing bladder 20 is placed in the rear end 911 of the groove 910, a liquid molding material is injected into the groove 910, so that the bottom of the groove 910 is entirely covered with a layer of the liquid molding material. The thickness of the liquid molding material may be the height of the protrusion edge 914 protruding into the groove 910, may be the height of the protrusion 913 protruding into the groove 910, or may be set according to practical situations, which is not limited herein.

Before step S106 is executed, the manufacturing method further includes the following steps.

Step S105, filling the popcorn into the grooves. After the shock absorbing bladder 20 is placed in the recess 910, the recess 910 is filled with popcorn 30. After the filling is completed, the liquid molding material is filled into the groove 910 to form the body 10 provided with the popcorn 30.

After step S106 is performed, the manufacturing method further includes the following steps.

Step S107, covering the pad surface on the liquid molding material, so that the pad surface and the liquid molding material are integrally molded. After the liquid molding material is filled into the recess 910, the pad 60 is covered on the liquid molding material. After the cover mold 92 is covered on the bottom mold 91, the stopper 920 of the cover mold 92 fixes the pad surface 60 in the groove 910, and the pad surface 60 is tightly attached to the liquid molding material. After the mold 90 is heated, the pad surface 60 is integrally formed with the liquid molding material, and the pad surface 60 covers the side of the main body 10 close to the upper end surface 23.

In the embodiment, the damping air bag is directly placed into the mold, the liquid-state forming material is filled into the mold and heated, and then the damping insole can be formed. Before the shock attenuation gasbag was put into the recess, at the liquid forming material of the bottom coating of recess, can effectively prevent because liquid forming material mobility is not strong, can't flow to the lower terminal surface of shock attenuation gasbag, lead to the lower terminal surface of shock attenuation gasbag can't be clad by liquid forming material to improve the yield of product. The opening arranged on the reinforcing part is convenient for the liquid molding material to flow to the second limiting hole from the opening, so that the liquid molding material can better coat the damping air bag. Simultaneously, the diameter of opening is less than the minimum size of puffed rice, can effectively prevent that puffed rice from falling into the spacing downthehole of second from the opening part. Set up lug and protruding edge in the mould, except can be with shock attenuation gasbag location in the mould, can also form corresponding line in one side of shock attenuation shoe-pad. The lines can effectively increase the friction force of the damping insole, so that the damping insole can be more firmly fixed in the shoe. The limiting blocks arranged on the cover die can fix the pad surface in the grooves and can also form concave parts on the damping insoles. The concave part can be matched with the heel of the foot of the human body, so that the wearing feeling of a user is more comfortable.

Since the manufacturing method of the shock-absorbing insole is used for manufacturing the shock-absorbing insoles of all the embodiments, at least all the beneficial effects brought by the technical scheme of the embodiments are achieved, and no further description is given here.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention.
