Description

Technical Field

[0001] This utility model relates to the field of shoe manufacturing technology, specifically to a shoe extrusion bonding mold. Background Technology

[0002] In the footwear industry, shoe extrusion is a crucial step, directly impacting the shoe's comfort, appearance, and durability. Traditional shoe extrusion methods often employ mechanical pressing or manual shaping, which are not only inefficient but also struggle to guarantee accuracy and consistency. Furthermore, mechanical pressing relies on a push-block method, essentially a traditional point-to-point pressing, which can result in missed areas and cause the shoe to open, affecting its final quality. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a shoe extrusion bonding mold, which solves the problems mentioned in the background.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a shoe extrusion bonding mold, comprising:

[0005] The base one heel and the base two heel have the same structure;

[0006] The shoe toe compression airbag heel and the shoe heel compression airbag heel are respectively connected and fixed to the base one heel and the base two heel, and each has a shoe toe compression reserved cavity heel and a shoe heel compression reserved cavity heel;

[0007] The base one heel and base two heel can inject gas into the corresponding airbags, causing the airbags to expand, thereby making the reserved cavity fit tightly with the toe and heel of the shoe, achieving a full-coverage fit.

[0008] Furthermore, the base heel has a pre-installed air nozzle connector at the end opposite to the toe compression airbag heel, and an air passage heel is opened inside the base heel. The air nozzle connector heel, the air passage heel, and the toe compression airbag heel are interconnected.

[0009] Furthermore, the base has a protrusion at one end of the heel facing the toe of the shoe, and the opening of the toe-compressing airbag covers the outside of the protrusion.

[0010] Furthermore, the shoe extrusion mold also includes several pressure plate heels, which are used to press the covered air bladder opening tightly onto the raised surface and connect and fix it with the screw holes on the protrusion by screws to achieve the sealing of the air bladder.

[0011] Furthermore, the shape and size of the toe extrusion cavity, the heel, and the heel extrusion cavity match the toe and heel of the shoe to be extruded.

[0012] Furthermore, both the first and second base heels are made of metal.

[0013] Furthermore, the toe compression airbag is located at the upper part of the toe compression reserved cavity, and the airbag is made of a soft material and can be inflated.

[0014] Furthermore, the heel compression airbag is disposed in the arc-shaped opening of the heel compression reserved cavity, and the airbag is made of a soft material and can be inflated.

[0015] This invention provides a shoe extrusion bonding mold. Compared with the prior art, it has the following advantages:

[0016] Gas is injected into the air bladders at both ends to inflate them, which then press the upper together. This causes the upper and insole to press down again, ensuring a precise fit between the edge of the upper and the inner edge of the insole. Glue is applied before bonding. This bonding method allows for full-range wrapping and compression of the toe and heel, meeting the compression needs of different styles and sizes of shoes. It provides the footwear industry with an efficient and reliable compression solution, effectively improving shoe production efficiency and quality. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 This utility model provides a technical solution: a shoe extrusion bonding mold, mainly composed of base 1, base 2, toe extrusion airbag 3, and heel extrusion airbag 4. The toe extrusion airbag 3 and the heel extrusion airbag 4 are connected and fixed to base 1 and base 2 respectively. The adjacent ends of the toe extrusion airbag 3 and the heel extrusion airbag 4 are respectively provided with toe extrusion reserved cavity 31 and heel extrusion reserved cavity 41. Base 1 and base 2 can inject gas into the toe extrusion airbag 3 and the heel extrusion airbag 4 respectively, so that the toe extrusion airbag 3 and the heel extrusion airbag 4 expand, thereby making the toe extrusion reserved cavity 31 and the heel extrusion reserved cavity 41 tightly fit with the toe and heel of the shoe 5, and extruding the shoe 5.

[0026] The base 1 and base 2 have the same structure and are both made of metal. The end of base 1 away from the toe compression airbag 3 is provided with an air nozzle connector 11, and an air passage 12 is provided inside base 1. The air nozzle connector 11, the air passage 12 and the toe compression airbag 3 are all connected.

[0027] The base 1 has a protrusion at one end facing the toe of the shoe compression airbag 3. The opening of the shoe compression airbag 3 is covered by the protrusion. After being covered, the opening is pressed tightly against the surface of the protrusion by several pressure plates 6. The pressure plates 6 and the protrusion are connected and fixed by screws. The surface of the protrusion has screw holes that are compatible with the screws. In this way, the shoe compression airbag 3 can be sealed and will not leak when it is inflated.

[0028] The toe compression airbag 3 is located at the upper part of the toe compression reserved cavity, and the airbag is made of a soft material and can inflate.

[0029] The heel compression airbag 4 is set in the arc-shaped opening of the heel compression reserved cavity 41, and the airbag is made of a soft material and can be inflated;

[0030] The instruction manual is required because the airbag is a prior art product, and these inflatable products are conventional products. Therefore, conventional products will not be described in detail. However, the use of airbag inflation in this patent is an original technology of this patent. This solves a major technical problem and can achieve all-round coverage and compression, so that the insole and the upper are fully covered and fit together.

[0031] When using this extrusion mold, firstly, with the help of the pressure plate 6 and screws, the openings of the toe extrusion airbag 3 and the heel extrusion airbag 4 are connected and fixed to the base 1 and base 2 respectively. After connection, the toe of the shoe 5 is placed in the toe extrusion cavity 31 and the heel is placed in the heel extrusion cavity 41. Then, the air nozzle connectors 11 of the base 1 and base 2 are connected to the external air pipes and inflation equipment. When the inflation equipment is working, the gas will enter the interior of the toe extrusion airbag 3 and the heel extrusion airbag 4 through the air pipes, air nozzle connectors 11, and air passages 12, so that the toe extrusion airbag 3 and the heel extrusion airbag 4 are compressed. When the bladder 4 inflates, the toe compression cavity 31 and the heel compression cavity 41 will fit tightly against the surface of the toe and heel, thereby compressing the shoe 5. It should be noted that the inflation device has a timer function, and the amount of gas inflated per unit time is fixed. Users can set the timer according to their actual needs. That is to say, when the set inflation time or when the pressure sensor reaches a certain pressure value, inflation will stop immediately to prevent the toe compression bladder 3 and the heel compression bladder 4 from exploding due to over-inflation. The air pressure detection mechanism is existing technology, so it will not be described in detail.
