[0065] For example, the vacuum assembly 5 is a vacuum pump.

[0066] The manufacturing method of the shoe sole of the embodiment of the application comprises the following steps: placing the replaceable fixing member in the mold cavity with a flat inner bottom surface; placing the insert matched with the fixing member in the mold cavity; positioning the insert in the mold cavity by the fixing member; and connecting the insert to the preset position of the shoe sole bottom surface to form the shoe sole pattern.

[0067] Specifically, the replaceable fixing member is placed on the inner bottom surface of the mold cavity, a hollow part is formed between the mold cavity and the fixing member, the insert matched with the fixing member is placed in the mold cavity, the fixing member can position the insert, and then the insert is connected to the preset position of the shoe sole bottom surface to form the shoe sole pattern. Different inserts can be arranged to realize the setting of different shoe sole patterns, thereby reducing the production cost of the shoe sole mold for changing patterns.

[0068] The embodiment of the application avoids opening the bottom pattern in the mold cavity by the setting mode of the insert. Different shapes of the fixing member and the insert matched with each other can be set according to different requirements, so as to form different shoe sole patterns, realize the customization requirement of the shoe sole pattern, and reduce the production cost of the shoe sole for changing patterns.

[0069] Optionally, a plurality of fixing members and inserts can share a set of molds, so that the mold can become a universal mold. Different patterns are formed by the cooperation of the insert and the fixing member and the combination of the mold body, thereby reducing the risk that the bottom pattern on the mold is eliminated due to obsolescence, and further reducing the manufacturing cost of different shoe soles.

[0070] It can be understood that when the number of the insert is one, the insert is placed on the inner bottom surface of the mold cavity, the insert can cover the inner bottom surface of the mold cavity, and the outer wall surface of the insert abuts against the inner wall surface of the mold cavity to fix the insert in the mold cavity. When the number of the insert is a plurality, the plurality of inserts are sequentially placed in the mold cavity according to a certain arrangement order, and the plurality of inserts cover the upper surface of the mold cavity.

[0071] In some embodiments, the insert is placed in abutment with the fixing member in the mold cavity according to a predetermined matching relationship between the insert and the fixing member.

[0072] Specifically, the insert is matched with the fixing part, after the fixing part is placed on the inner bottom surface of the mold cavity, only the insert matched with the fixing part can be placed in the hollow formed between the fixing part and the insert according to the predetermined matching relationship, and the matching relationship between the insert and the fixing part improves the positioning accuracy of the fixing part to the insert.

[0073] In some embodiments, the manufacturing method of the shoe sole further comprises: placing the film on the upper surface of the mold cavity; heating the film; opening the vacuum extraction assembly to extract the air in the mold cavity so that the film is adsorbed on the surface of the mold cavity and the surface of the insert, and the film is connected with the insert.

[0075] Specifically, after the fixing part is placed in the mold cavity and the insert matched with the fixing part is placed, the bonding layer is coated on the insert to facilitate the bonding of the insert with the film, that is, the bonding layer is coated on the upper surface of the insert, and the fixing part is not provided with the bonding layer, so that the film is connected with the insert through the bonding effect of the bonding layer and the film, and the fixing part is facilitated to be separated.

[0076] The manufacturing method of the shoe sole of the embodiment of the present application places the fixing part in the mold cavity and places the insert matched with the fixing part, directly places the insert in the mold body, and sets the film and the bonding layer to connect the film with the insert and adsorb the film on the insert, and then pours the injection material on the film to form the midsole, thereby saving the process of bonding the large sole later.

[0078] In some embodiments, the thickness of the film is 0.2-0.5 mm, the size of the film is greater than the size of the mold cavity, the film comprises a matte surface and a bright surface, the matte surface is connected with the bonding layer, and the mold body is closed with the upper after the injection material is poured on the bright surface to be shaped.

[0079] Specifically, the film is placed above the insert, one side of the matte surface is connected with the insert, and one side of the bright surface is connected with the midsole with the upper surface facing upward, and the length and width dimensions of the film are greater than the length and width dimensions of the shoe sole mold to cover the mold body.

[0080] Optionally, the film wraps the lower surface of the midsole, and at the same time extends to the side surface of the midsole and wraps a predetermined height of the side surface of the midsole, that is, the film wraps part or all of the side surface of the midsole, the lower surface of the film covers the upper surface of the insert, and the upper surface of the film is connected to the midsole, so that the film can cover the bubble defects on the midsole and improve the appearance of the sole.

[0081] For example, the film is a TPU film, the thickness of the TPU film is 0.2-0.5 mm, the injection material is PU material, the film is a material that can carry liquid injection material, the liquid injection material is cooled to form the midsole, and the film is integrally combined with the midsole at the same time of cooling, so that the film and the midsole are integrally connected.

[0082] Optionally, the midsole is directly injection molded on the film, avoiding the cold bonding process of the film and the midsole and the insert, reducing the shoemaking process, and improving the production efficiency and product quality.
