[0002] In the current shoemaking process, the shoe sole and the shoe upper are separately formed, and then connected into one by bonding, sewing and other connection methods, which easily leads to the complication of the shoemaking process, poor connection stability of the shoe sole and the shoe upper, and problems such as glue opening and sewing thread relaxation at the connection between the shoe sole and the shoe upper after long-time wearing. SUMMARY

[0003] The present application aims to at least solve one of the problems in the prior art. To this end, the present application provides a shoe upper and shoe sole integrated forming process, which is beneficial to simplify the connection process of the shoe upper and the shoe sole and improve the connection stability of the shoe upper and the shoe sole.

[0004] The present application also provides a footwear accessory.

[0005] The present application also provides a shoe.

[0006] According to the shoe upper and shoe sole integrated forming process of the first aspect of the present application, the shoe upper and shoe sole integrated forming process comprises:

[0007] providing a forming mold and a sheet material in standby, the forming mold comprising a first mold base and a second mold base, the first mold base being provided with a shoe upper forming part and a shoe sole forming part, the edge of the shoe upper forming part being connected with the edge of the shoe sole forming part, the second mold base being provided with a shoe upper shaping part and a shoe sole shaping part, the edge of the shoe upper shaping part being connected with the edge of the shoe sole shaping part;

[0008] placing the sheet material on the parting surface of the forming mold;

[0009] closing the first mold base and the second mold base, embedding the shoe upper forming part and the shoe upper shaping part to form the shoe upper from the sheet material, and embedding the shoe sole forming part and the shoe sole shaping part to form the insole from the sheet material, wherein the shoe upper and the insole are integrally formed;

[0010] folding the insole relative to the shoe upper, connecting the edge of the insole with the edge of the shoe upper, and obtaining a shoe roughcast.

[0011] The integrated molding process for the upper and sole according to embodiments of the present invention has at least the following beneficial effects: the molding mold includes a first mold base and a second mold base, wherein the first mold base is provided with both an upper molding part and a sole molding part, and the second mold base is provided with both an upper shaping part and a sole shaping part. The upper molding part corresponds to the upper shaping part, and the sole molding part corresponds to the sole shaping part. The user can place the sheet material on the parting surface of the molding mold. After the first mold base and the second mold base are closed, the upper molding part and the upper shaping part are fitted together. Under the joint extrusion action of the upper molding part and the upper shaping part, the sheet material... The upper is formed, and at the same time, the sole forming part and the sole shaping part are fitted together. Under the joint extrusion of the sole forming part and the sole shaping part, the sheet material forms the insole. Since the edge of the upper forming part is connected to the edge of the sole forming part, one side of the upper is connected to one side of the insole, that is, the upper and the insole are formed as one piece. After the insole is folded relative to the upper to the lower end of the upper, it is connected to the edge of the upper through the edge of the insole. The upper and the insole together form a shoe blank that can be worn by the human foot. This helps to simplify the connection process between the upper and the sole and improve the connection stability between the upper and the sole.

[0012] According to some embodiments of the present invention, one of the upper forming part and the upper shaping part is provided with an opening divider block at the corresponding shoe opening, and the other is provided with an opening divider groove at the corresponding shoe opening;

[0013] The one-piece molding process for the upper and sole also includes:

[0014] The first mold base and the second mold base are joined together to fit the shoe opening separator block and the shoe opening separator groove, so that shoe opening indentation is formed on the shoe surface at the corresponding shoe opening separator block or shoe opening separator groove.

[0015] Cut the upper along the creases at the shoe opening to form the shoe opening.

[0016] Specifically, considering that the shoe upper needs to be cut to form the shoe opening at the end away from the sole, one of the shoe upper forming part and the shoe upper shaping part is provided with a shoe opening dividing block at the corresponding shoe opening, and the other is provided with a shoe opening dividing groove at the corresponding shoe opening. Under the mutual pressing action of the first mold base and the second mold base, the shoe opening dividing block and the shoe opening dividing groove fit together, so that the shoe upper forms a shoe opening indentation corresponding to the shape of the shoe opening dividing block or the shoe opening dividing groove. The user cuts the shoe upper along the shoe opening indentation to form the shoe opening, which helps to simplify the shoe manufacturing process and improve the shoe manufacturing efficiency.

[0017] According to some embodiments of the present invention, the process of integral molding of the upper and sole further includes:

[0018] Provide edge binding strips for spare use;

[0019] Wrap the binding strip around the edge of the shoe opening and connect the binding strip to the shoe upper.

[0020] Considering that after the shoe opening is cut, there are many burrs on the edge of the shoe opening, which can easily cause scratches and friction to the wearer, the one-piece molding process of the shoe opening and sole can cover the edge of the shoe opening with the binding strip and connect the binding strip to the shoe opening. By covering the edge of the shoe opening with the binding strip, the cut marks at the edge of the shoe opening can be hidden and the scratches and friction caused to the wearer by the burrs at the edge of the shoe opening can be reduced.

[0021] According to some embodiments of the present invention, the process of integral molding of the upper and sole further includes:

[0022] Provide spare outsoles;

[0023] After obtaining the rough shoe blank, the outsole is attached to the end of the insole away from the upper to obtain the finished shoe.

[0024] Considering that in the one-piece molding process of upper and sole, the insole and upper are molded as one piece, and the insole is difficult to achieve sufficient hardness or elasticity, this one-piece molding process connects the edge of the insole to the edge of the upper, and then connects the outsole to the end of the insole away from the upper. That is, the insole is located between the outsole and the upper to obtain the finished shoe, which helps to improve the durability of the finished shoe and the comfort of the wearer.

[0025] According to some embodiments of the present invention, the junction between the upper forming part and the sole forming part corresponds to the outer waist of the shoe blank.

[0026] Specifically, the junction of the upper molding section and the sole molding section forms the outer waist of the shoe blank, which helps to reduce the gap between the upper molding section and the sole molding section, so that the molded upper and the insole are connected as one piece, simplifying the connection process between the upper and the insole. By folding the upper relative to the insole, combined with the sewing process, the upper and the insole can be connected as one piece. The integral connection between the upper and the insole is located on the outer waist of the shoe blank, which helps to enhance the strength of the outer waist and avoid the problem of the shoe breaking due to the seam breaking at the outer waist.

[0027] According to some embodiments of the present invention, the first mold base is provided with a dividing strip at the junction of the upper forming part and the sole forming part.

[0028] The first mold base has a dividing strip at the junction of the upper molding part and the sole molding part. When the first mold base and the second mold base are molded together, the molding pressure of the first mold base and the second mold base will form a dividing indentation between the one-piece molded insole and the upper. This allows the user to fold the upper and the insole together along the dividing indentation so that the insole covers the lower part of the upper. Combined with the sewing process, the upper and the insole are connected as one piece, thereby forming a cavity that can accommodate the human foot. This simplifies the connection process between the upper and the insole.

[0029] According to some embodiments of the present invention, folding the insole relative to the upper includes:

[0030] A dividing line is formed at the dividing line of the sheet material, and the insole is folded up relative to the upper along the dividing line.

[0031] Under the squeezing action of the first mold and the second mold, a dividing indentation is formed at the dividing strip of the sheet. The dividing indentation helps the user distinguish the outline of the upper and the insole. The user can fold the insole relative to the upper along the dividing indentation so that the insole is folded to the lower end of the upper. The connection between the edge of the insole and the edge of the upper closes the lower opening of the upper, forming a cavity that can be worn by the human body.

[0032] According to some embodiments of the present invention, the rear end of the shoe upper shaping part is provided with an arc-shaped groove, the left end of the arc-shaped groove extends to the left end of the shoe upper shaping part, and the right end of the arc-shaped groove extends to the right end of the shoe upper shaping part.

[0033] Sheet materials are used to form the shoe upper, including:

[0034] The inner surface of the shoe upper has an arc-shaped retaining strip forming at the arc-shaped retaining groove.

[0035] Considering the fit between the shoe and the human foot, the rear end of the upper shaping part is provided with an arc-shaped groove. The left end of the arc-shaped groove extends to the left end of the upper shaping part, and the right end of the arc-shaped groove extends to the right end of the upper shaping part. Under the action of the mold closing, an arc-shaped retaining strip is formed on the inner surface of the upper corresponding to the arc-shaped groove. The arc-shaped retaining strip is set to correspond to the heel of the human foot. The contact between the arc-shaped retaining strip and the human foot helps to improve the user's wearing comfort and the fit between the shoe and the foot.

[0036] According to some embodiments of the present invention, the lower surface of the sole shaping part is provided with a plurality of partitioned grooves, which together with the sole forming part define a plurality of partitioned cavities;

[0037] Sheets form the insole of the shoe, including:

[0038] The insole of the shoe has partitioned protrusions at the corresponding partitioned grooves.

[0039] The lower surface of the sole shaping part is provided with multiple partitioned grooves. These grooves, together with the sole forming part, define multiple partitioned cavities. When the sheet material covers the sole forming part and the sole shaping part, multiple partitioned cavities are formed under the combined extrusion of the first mold and the second mold. This allows the sheet material to form multiple partitioned protrusions on the insole under the extrusion of the multiple partitioned cavities. This enhances the comfort of the insole made by the one-piece molding process of the upper and sole, helps control the bending area of ​​the insole, and improves the service life of the insole.

[0040] According to a second aspect of the present invention, the footwear accessory is manufactured using the one-piece molding process for the upper and sole as shown in the first aspect.

[0041] The footwear accessories according to embodiments of the present invention have at least the following beneficial effects: the footwear accessories are manufactured using the one-piece molding process for the upper and sole as shown in the first aspect. The molding mold includes a first mold base and a second mold base, wherein the first mold base is provided with both an upper molding part and a sole molding part, and the second mold base is provided with both an upper shaping part and a sole shaping part. The upper molding part corresponds to the upper shaping part, and the sole molding part corresponds to the sole shaping part. The user can place the sheet material on the parting surface of the molding mold. After the first mold base and the second mold base are closed, the upper molding part and the upper shaping part are fitted together. Under the same extrusion action, the sheet material forms the shoe upper. At the same time, the sole forming part and the sole shaping part are fitted together. Under the joint extrusion action of the sole forming part and the sole shaping part, the sheet material forms the shoe insole. Since the edge of the upper forming part is connected to the edge of the sole forming part, one side of the upper is connected to one side of the insole, that is, the upper and the insole are formed as one piece. After the insole is folded relative to the upper to the lower end of the upper, it is connected to the edge of the upper through the edge of the insole. The upper and the insole together form a shoe blank that can be worn by the human foot. This helps to simplify the connection process between the upper and the sole and improve the connection stability between the upper and the sole.

[0042] The shoes according to a third aspect of the present invention include footwear accessories as shown in the second aspect.

[0043] The shoes according to embodiments of the present invention have at least the following beneficial effects: the shoes include the footwear accessories shown in the second aspect, and the molding die includes a first mold base and a second mold base. The first mold base is provided with both an upper forming part and a sole forming part. Correspondingly, the second mold base is provided with both an upper shaping part and a sole shaping part. The upper forming part corresponds to the upper shaping part, and the sole forming part corresponds to the sole shaping part. The user can place the sheet material on the parting surface of the molding die. After the first mold base and the second mold base are closed, the upper forming part and the upper shaping part fit together. Under the joint pressing action of the upper forming part and the upper shaping part... This process allows the sheet material to form the upper, while the sole forming part and the sole shaping part are fitted together. Under the joint compression of the sole forming part and the sole shaping part, the sheet material forms the insole. Since the edge of the upper forming part is connected to the edge of the sole forming part, one side of the upper is connected to one side of the insole, that is, the upper and the insole are formed as one piece. After the insole is folded relative to the lower end of the upper, it is connected to the edge of the upper through the edge of the insole. The upper and the insole together form a shoe blank that can be worn by the human foot, which helps to simplify the connection process between the upper and the sole and improve the connection stability between the upper and the sole.

[0064] Reference Figures 1 to 10 As shown, an embodiment of the present invention describes a process for integral molding of the shoe upper and sole, comprising the following steps:

[0065] Step S100: Provide a molding die and sheet material for use. The molding die includes a first mold base 100 and a second mold base 200. The first mold base 100 is provided with an upper forming part 110 and a sole forming part 120. The edge of the upper forming part 110 is connected to the edge of the sole forming part 120. The second mold base 200 is provided with an upper shaping part 210 and a sole shaping part 220. The edge of the upper shaping part 210 is connected to the edge of the sole shaping part 220.

[0066] Step S200: Place the sheet material on the parting surface of the forming mold;

[0067] In step S300, the first mold base 100 and the second mold base 200 are closed, and the upper forming part 110 and the upper shaping part 210 are fitted together to form the upper 310 from the sheet material. The sole forming part 120 and the sole shaping part 220 are fitted together to form the insole 320 from the sheet material. The upper 310 and the insole 320 are integrally formed.

[0068] In step S400, the insole 320 is folded over the upper 310 and the edge of the insole 320 is connected to the edge of the upper 310 to obtain a rough shoe blank.

[0069] Reference Figure 1 , Figure 2 and Figure 3 As shown, the molding die includes a first mold base 100 and a second mold base 200. The first mold base 100 is provided with an upper forming part 110 and a sole forming part 120. Correspondingly, the second mold base 200 is provided with an upper shaping part 210 and a sole shaping part 220. The upper forming part 110 corresponds to the upper shaping part 210, and the sole forming part 120 corresponds to the sole shaping part 220.

[0070] Reference Figure 4 , Figure 5 and Figure 6As shown, the user can place the sheet material on the parting surface of the molding die. After the first mold base 100 and the second mold base 200 are closed, the upper forming part 110 and the upper shaping part 210 are fitted together. Under the joint extrusion action of the upper forming part 110 and the upper shaping part 210, the sheet material forms the upper 310. At the same time, the sole forming part 120 and the sole shaping part 220 are fitted together. Under the joint extrusion action of the sole forming part 120 and the sole shaping part 220, the sheet material forms the insole 320. And because the edge of the upper forming part 110 and the sole forming part 120 are fitted together, the sheet material forms the insole 320. The edges of the upper 310 and the insole 320 are joined together, so that one side of the upper 310 is connected to one side of the insole 320. That is, the upper 310 and the insole 320 are integrally formed to form a composite body 300. After the insole 320 is folded over relative to the lower end of the upper 310, it is connected to the edge of the upper 310 through the edge of the insole 320. The upper 310 and the insole 320 together form a shoe blank that can be worn by the human foot. As part of the sole, the insole 320 helps to simplify the connection process between the upper 310 and the sole and improve the connection stability between the upper 310 and the sole.

[0071] Reference Figure 2 and Figure 3 As shown, it is understandable that, considering the need to cut the shoe opening 330 at the end of the upper 310 away from the insole 320, one of the upper forming part 110 and the upper shaping part 210 has a shoe opening divider block 111 at the corresponding shoe opening 330, and the other has a shoe opening divider groove 211 at the corresponding shoe opening 330. Specifically, the upper forming part 110 has a shoe opening divider block 111, while the upper shaping part 210 has a shoe opening divider groove 211.

[0072] See Figure 7 As shown, the process of molding the upper and sole together also includes the following steps:

[0073] Step S510: The first mold base 100 and the second mold base 200 are molded together, so that the shoe opening dividing block 111 and the shoe opening dividing groove 211 are fitted together, so that shoe opening indentation is formed on the shoe surface 310 corresponding to the shoe opening dividing block 111 or the shoe opening dividing groove 211.

[0074] Step S520: Cut the upper 310 along the shoe opening crease so that the upper 310 forms the shoe opening 330.

[0075] Step S530: Provide edge binding strips for later use;

[0076] In step S540, the binding strip is wrapped around the edge of the shoe opening 330 and connected to the shoe upper 310.

[0077] See Figure 7As shown, in steps S510 and S520, under the mutual pressing action of the first mold base 100 and the second mold base 200, the shoe opening separator 111 and the shoe opening separator groove 211 are fitted together, so that the shoe upper 310 forms a shoe opening indentation corresponding to the shape of the shoe opening separator 111 or the shoe opening separator groove 211. The user cuts the shoe upper 310 along the shoe opening indentation so that the shoe upper 310 forms the shoe opening 330, which helps to simplify the shoe manufacturing process and improve the shoe manufacturing efficiency.

[0078] See Figure 7 As shown, the shoe upper and sole integral molding process involves setting shoe opening separators 111 and shoe opening separators 211 on the molding die, so that the pressed shoe upper 310 forms shoe opening indentations corresponding to the shape of the shoe opening separators 111 or shoe opening separators 211. The shoe opening indentations can guide the user's cutting and help improve the consistency of product production.

[0079] See Figure 7 As shown, in steps S530 and S540, considering that after the shoe opening 330 of the upper 310 is cut, there are many burrs on the edge of the shoe opening 330, which are easy to cause scratches and friction to the wearer, the shoe upper and sole integral molding process can cover the edge of the shoe opening 330 with the edge strip. The outer edge of the edge strip extends to the outer surface of the upper 310, and the inner edge of the edge strip extends to the inner surface of the upper 310, thereby realizing the edge strip wrapping the edge of the shoe opening 330.

[0080] Specifically, users can use sewing to connect the binding strip to the upper 310 as a whole, and make the binding strip cover the edge of the shoe opening 330 and connect the binding strip to the upper 310. By covering the edge of the shoe opening 330, the cut marks at the edge of the shoe opening 330 can be hidden, and the burrs at the edge of the shoe opening 330 can be reduced to reduce the scratches and friction caused to the wearer.

[0081] The sheet material is pressed by the upper forming part 110 and the upper shaping part 210 to form the upper 310. The upper 310 has an open opening. After the user cuts the upper 310 along the shoe opening crease, the upper 310 has a shoe opening 330. The shoe opening 330 is set opposite to the open opening. The upper 310 is arranged in a ring, that is, the upper 310 has a forefoot and a heel counter. The rear end of the forefoot is connected to the front end of the heel counter. The forefoot and heel counter are integrally formed to form the upper 310, which helps to enhance the wrapping performance of the human foot and simplifies the forming process of the upper 310.

[0082] It should be understood that, in another embodiment, the upper forming part 110 is provided with a shoe opening dividing groove 211, and the upper shaping part 210 is provided with a shoe opening dividing block 111. By fitting the shoe opening dividing groove 211 and the shoe opening dividing block 111 together, the upper 310 can also form a shoe opening indentation, so that the user can cut the upper 310 along the shoe opening indentation. After cutting, the upper 310 forms a shoe opening 330 at the shoe opening indentation that allows the human foot to enter and exit.

[0083] See Figure 10 As shown, it can be understood that in this embodiment, the process of integrally molding the upper and sole also includes:

[0084] Step S610: Provide a spare outsole for the shoe;

[0085] In step S620, after obtaining the shoe blank, the outsole is connected to the end of the insole 320 away from the upper 310 to obtain the finished shoe.

[0086] Considering that in the one-piece molding process of the upper and sole, the insole 320 and the upper 310 are molded as one piece, and the insole 320 is difficult to achieve sufficient hardness or elasticity, after connecting the edge of the insole 320 to the edge of the upper 310, the outsole can be connected to the end of the insole 320 away from the upper 310. That is, the insole 320 is located between the outsole and the upper 310 to obtain the finished shoe, which is beneficial to improving the durability of the finished shoe and the comfort of the wearer.

[0087] Specifically, the outsole can be connected to the insole 320 by adhesive bonding, and the outsole and insole 320 are connected as one piece. The outsole is used to contact the ground and other supporting surfaces, while the insole 320 is used to contact the sole of the foot. The outsole and insole 320 work together to absorb shock, which helps to improve the wearer's comfort.

[0088] See Figure 1 and Figure 6 As shown, it can be understood that in step S100, the second mold base 200 and the first mold base 100 are arranged vertically, that is, the first mold base 100 serves as the lower mold base and the second mold base 200 serves as the upper mold base. Specifically, the upper forming part 110 and the sole forming part 120 are grooves, located on the upper surface of the first mold base 100, while the upper shaping part 210 and the sole shaping part 220 are protrusions, located on the lower surface of the second mold base 200.

[0089] The forming mold can be applied to a hot press. Under the driving action of the hot press, the first mold base 100 and the second mold base 200 are brought closer or further apart. The hot press can heat the first mold base 100 or the second mold base 200, so that the sheet material is deformed under the combined action of temperature and pressure. The sheet material can be made of various heat-pressable materials such as cotton and leather.

[0090] Understandably, considering that when a person is exercising while wearing shoes, the outer part of the shoe bears a large load, and during intense exercise, the outer part of the shoe is prone to problems such as glue coming undone or stitching breaking.

[0091] The junction of the upper forming part 110 and the sole forming part 120 is used to form the outer waist of the shoe blank. Correspondingly, the junction of the upper shaping part 210 and the sole shaping part 220 is provided corresponding to the outer waist of the shoe blank.

[0092] The junction of the upper molding part 110 and the sole molding part 120 corresponds to the outer waist of the shoe, which helps to reduce the gap between the upper molding part 110 and the sole molding part 120, so that the molded upper 310 and the insole 320 are connected as one piece, thereby simplifying the connection process between the upper 310 and the sole. By folding the upper 310 relative to the insole 320, combined with the sewing process, the upper 310 and the insole 320 can be connected as one piece. The integral connection between the upper 310 and the insole 320 is located on the outer waist of the shoe blank, which helps to enhance the strength of the outer waist of the shoe blank and reduce the risk of shoe damage caused by glue separation or seam breakage at the outer waist.

[0093] It should be noted that, taking the left shoe as an example, the "outer waist" of the shoe refers to the left side of the middle of the shoe. A molding die is used to create a composite 300 connecting the upper 310 and the insole 320. The composite 300 has an integrally molded upper 310 and insole 320. By folding the insole 320 to the lower right, the insole 320 closes the lower end of the upper 310. Combined with sewing, the insole 320 and the upper 310 are connected as one piece. Similarly, taking the right shoe as an example, the "outer waist" of the shoe refers to the right side of the middle of the shoe. A molding die is used to create a composite 300 connecting the upper 310 and the insole 320. The composite 300 has an integrally molded upper 310 and insole 320. By folding the insole 320 to the lower left, the insole 320 closes the lower end of the upper 310. Combined with sewing, the insole 320 and the upper 310 are connected as one piece.

[0094] Reference Figure 2 and Figure 3 As shown, it can be understood that the rear end of the shoe upper shaping part 210 is provided with an arc-shaped groove 212, the left end of the arc-shaped groove 212 extends to the left end of the shoe upper shaping part 210, and the right end of the arc-shaped groove 212 extends to the right end of the shoe upper shaping part 210.

[0095] Reference Figure 8 As shown, in step S300, the sheet material is used to form the shoe upper 310, which includes the following steps:

[0096] In step S310, an arc-shaped retaining strip 340 is formed on the inner surface of the shoe upper 310 at the arc-shaped retaining groove 212.

[0097] Reference Figure 8 As shown, considering the fit between the shoe and the human foot, the rear end of the shoe upper shaping part 210 is provided with an arc-shaped groove 212. The left end of the arc-shaped groove 212 extends to the left end of the shoe upper shaping part 210, and the right end of the arc-shaped groove 212 extends to the right end of the shoe upper shaping part 210. Under the squeezing action of the first mold base 100 and the second mold base 200, an arc-shaped strip 340 is formed on the inner surface of the shoe upper 310. The arc-shaped strip 340 is set to correspond to the heel of the human foot. The contact between the arc-shaped strip 340 and the human foot helps to improve the comfort of the user and the fit between the shoe and the foot.

[0098] Reference Figure 8 As shown, the lower surface of the sole shaping part 220 is provided with a plurality of partitioned grooves 221, which together with the sole forming part 120 define a plurality of partitioned cavities.

[0099] In step S300, the sheet material forms the insole 320, including the following steps:

[0100] In step S320, partitioned protrusions 321 are formed at the corresponding partitioned grooves 221 on the insole 320 of the shoe.

[0101] Reference Figure 8 As shown, the lower surface of the sole shaping part 220 is provided with multiple partitioned grooves 221. The partitioned grooves 221 can jointly define multiple partitioned cavities with the sole forming part 120. When the sheet material covers the space between the sole forming part 120 and the sole shaping part 220, multiple partitioned cavities are formed by the first mold base 100 and the second mold base 200. Under the extrusion action of the multiple partitioned cavities, the insole 320 forms multiple partitioned protrusions 321, thereby enhancing the comfort of the sole made by the user using the molding die, helping to control the bending area of ​​the sole, and improving the service life of the sole.

[0102] Reference Figure 2 and Figure 3As shown, it can be understood that the first mold base 100 has a dividing strip 130 at the junction of the upper forming part 110 and the sole forming part 120. When the first mold base 100 and the second mold base 200 are molded together, under the mold-forming pressure of the first mold base 100 and the second mold base 200, a dividing indentation is formed between the integrally molded insole 320 and the upper 310. This allows the user to fold the upper 310 and the insole 320 together along the dividing indentation so that the insole 320 covers the lower end of the upper 310. With the help of the sewing process, the upper 310 and the insole 320 are connected as one piece, thereby forming a cavity that can accommodate the human foot, which helps to simplify the connection process between the upper 310 and the sole.

[0103] Reference Figure 2 and Figure 3 As shown, in step S300, the upper forming part 110 and the upper shaping part 210 are fitted together to form an upper forming cavity. Under the pressing action of the upper forming cavity, the sheet material forms the upper 310, and an upper indentation is formed at the edge of the upper 310. The sole forming part 120 and the sole shaping part 220 are fitted together to form a sole forming cavity. Under the pressing action of the sole forming cavity, the sheet material forms the insole 320, and an insole indentation is formed at the edge of the insole 320. The user can trim the excess edge of the sheet material along the upper indentation and the insole indentation to obtain an assembly 300 containing the upper 310 and the insole 320, so as to facilitate the subsequent folding of the insole 320 relative to the upper 310 and the connection of the insole 320 and the upper 310.

[0104] Reference Figure 9 As shown, in step S400, the insole 320 is folded relative to the upper 310, including:

[0105] Step S410: Create a dividing line indentation at the dividing strip 130 on the sheet material, and fold the insole 320 relative to the upper 310 along the dividing line indentation.

[0106] Under the compression of the first mold base 100 and the second mold base 200, a dividing indentation is formed on the sheet material at the dividing strip 130. The dividing indentation helps the user distinguish the outline boundary between the upper 310 and the insole 320. The user can fold the insole 320 relative to the upper 310 along the dividing indentation so that the insole 320 is folded to the lower end of the upper 310. The connection between the edge of the insole 320 and the edge of the upper 310 closes the lower opening of the upper 310, forming a cavity that can be worn by the human body.

[0107] Understandably, the sheet material includes multiple layers of different materials. By stacking and hot-pressing multiple layers of different materials, the insole 320 can simultaneously function as both an insole and a sole. The formed shoe blank does not need to have an insole inside, which simplifies the shoe production process and improves production efficiency. The inner layer of the upper 310 can be made of flexible material, making the upper 310 more skin-friendly, while the outer layer of the sole can be made of rigid material, which helps to protect the feet.

[0108] One embodiment of the present invention provides a footwear accessory manufactured using the one-piece molding process for the upper and sole as described in the above embodiment.

[0109] The molding die includes a first mold base 100 and a second mold base 200. The first mold base 100 is provided with an upper forming part 110 and a sole forming part 120. Correspondingly, the second mold base 200 is provided with an upper shaping part 210 and a sole shaping part 220. The upper forming part 110 corresponds to the upper shaping part 210, and the sole forming part 120 corresponds to the sole shaping part 220. The user can place the sheet material on the parting surface of the molding die. After the first mold base 100 and the second mold base 200 are closed, the upper forming part 110 and the upper shaping part 210 fit together. Under the joint extrusion action of the upper forming part 110 and the upper shaping part 210, the sheet material is formed into the upper 310, and the sole forming part 120 and the sole shaping part 220 are formed. The insole is formed by the joint compression of the sole forming part 120 and the sole shaping part 220. The sheet material is then used to form the insole 320. Since the edge of the upper forming part 110 is connected to the edge of the sole forming part 120, one side of the upper 310 is connected to one side of the insole 320. That is, the upper 310 and the insole 320 are integrally formed. After the insole 320 is folded relative to the upper 310, the insole 320 is folded to the lower end of the upper 310. The edge of the insole 320 is connected to the edge of the upper 310. The upper 310 and the insole 320 together form a shoe blank that can be worn by the human foot. This simplifies the connection process between the upper 310 and the sole and improves the connection stability between the upper 310 and the sole.

[0110] One embodiment of the present invention provides a shoe that includes the footwear accessories shown in the above embodiment.

[0111] The molding die includes a first mold base 100 and a second mold base 200. The first mold base 100 is provided with an upper forming part 110 and a sole forming part 120. Correspondingly, the second mold base 200 is provided with an upper shaping part 210 and a sole shaping part 220. The upper forming part 110 corresponds to the upper shaping part 210, and the sole forming part 120 corresponds to the sole shaping part 220. The user can place the sheet material on the parting surface of the molding die. After the first mold base 100 and the second mold base 200 are closed, the upper forming part 110 and the upper shaping part 210 fit together. Under the joint extrusion action of the upper forming part 110 and the upper shaping part 210, the sheet material is formed into an upper 310. At the same time, the sole forming part 120 and the sole shaping part 220 fit together. 20. Under the joint extrusion of the sole forming part 120 and the sole shaping part 220, the sheet material forms the insole 320. Since the edge of the upper forming part 110 is connected to the edge of the sole forming part 120, one side of the upper 310 is connected to one side of the insole 320. That is, the upper 310 and the insole 320 are integrally formed. After the insole 320 is folded relative to the upper 310, after the insole 320 is folded to the lower end of the upper 310, the edge of the insole 320 is connected to the edge of the upper 310. The upper 310 and the insole 320 together form a shoe blank that can be worn by the human foot. This helps to simplify the connection process between the upper 310 and the sole and improve the connection stability between the upper 310 and the sole.

[0112] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
