[0044] The technical solution of the present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments. Example

[0045] This embodiment provides an integrally formed snowboard, such as Figure 1 As shown, it includes: a first fiber layer 1, a second fiber layer 2 and a foaming layer 3.

[0046] The second fiber layer 2 is integrally connected to the first fiber layer 1 , and a closed cavity is formed between the second fiber layer 2 and the first fiber layer 1 ; the foaming layer 3 is filled in the cavity.

[0047] The one-piece snowboard provided in this embodiment has a first fiber layer 1 and a second fiber layer 2 that are connected by one-piece molding in a mold under a high temperature and high pressure environment. The one-piece molding does not require secondary processing, and the structure is stable and not easy to break or crack. The fiber material constitutes the external structure of the snowboard, and the foaming material serves as the internal support of the snowboard. The material is lightweight, and the weight is reduced by at least 20% compared to the traditional multi-layer snowboard. There is no secondary processing, the production efficiency is high, and the production cost is reduced compared to the traditional multi-layer snowboard.

[0048] Preferably, in the one-piece snowboard of this embodiment, the first fiber layer 1 and / or the second fiber layer 2 are made of carbon fiber or glass fiber, which helps to reduce the overall weight of the snowboard.

[0049] This embodiment provides a snowboard mold for manufacturing the above-mentioned one-piece snowboard, including:

[0050] an upper mold 4, the inner side of which is used to accommodate the first fiber layer 1;

[0051] a lower layer mold 5, the inner side of the lower layer mold 5 is used to accommodate the second fiber layer 2;

[0052] The upper mold 4 can be assembled with the lower mold 5 to form a molding area of ​​the snowboard inside.

[0053] The snowboard mold of this embodiment, such as Figure 2 As shown, firstly, a foaming layer 3 is formed inside, and after the upper mold 4 and the lower mold 5 are assembled, the foaming material is filled inside, and the foaming material fills the inside of the snowboard mold. Then, the upper and lower sides of the foaming layer 3 are respectively coated with the prepregs of the first fiber layer 1 and the second fiber layer 2 prepared in advance. In order to facilitate the prepreg coating on the surface of the foaming layer 3, one side of the prepreg is coated with glue so as to be adhered to the surface of the foaming layer 3. After the prepreg coating is completed, as shown in FIG. Figure 3 As shown, the prepreg and the foaming layer 3 are placed between the upper mold 4 and the lower mold 5, and the molds are closed and heated and pressurized. Under high temperature and high pressure, the first fiber layer 1, the second fiber layer 2 and the foaming layer 3 are cured and formed into a whole, and no glue is applied for secondary bonding. Among them, the foaming layer 3 has the ability to shrink, so after the initial molding, it can be accommodated in the cavity by pressing the first fiber layer 1 and the second fiber layer 2.

[0054] Preferably, the snowboard mold of this embodiment further includes a pressurizing mechanism, which is used to press the upper mold 4 and the lower mold 5 tightly, so that the first fiber layer 1 and the second fiber layer 2 can be closely contacted and connected as a whole. The snowboard mold of this embodiment further includes a heating mechanism, which is used to heat the upper mold 4 and the lower mold 5 to make the interior of the snowboard mold reach a high temperature environment, which facilitates the fiber material and the foaming material to be connected as a whole. Example

[0055] This embodiment provides an integrally formed snowboard, such as Figure 4 As shown, it includes: a first fiber layer 1, a second fiber layer 2 and a foaming layer 3.

[0056] The second fiber layer 2 is integrally connected to the first fiber layer 1, and a closed cavity is formed between the second fiber layer 2 and the first fiber layer 1; the foaming layer 3 is filled in the cavity. The first fiber layer 1 and the second fiber layer 2 are arranged in a central symmetric manner;

[0057] The first fiber layer 1 and the second fiber layer 2 both include a curved surface portion 11 , a supporting portion 12 , and an edge reinforcement strip 13 .

[0058] The arc portion 11 is used as the surface of the snowboard; the support portion 12 is connected to the side of the arc portion 11 facing the chamber, and the two ends of the support portion 12 are respectively used to abut the arc portions 11 of the first fiber layer 1 and the second fiber layer 2. The edge reinforcement strip 13 is connected to one side edge of the arc portion 11.

[0059] In the one-piece snowboard of this embodiment, the inner sides of the first fiber layer 1 and the second fiber layer 2 both have supporting parts 12 for supporting functions. Figure 4 As shown, since the first fiber layer 1 and the second fiber layer 2 are designed as a centrally symmetrical structure, the first fiber layer 1 and the second fiber layer 2 are actually the same product in terms of structure, so the raw materials used during manufacturing are the same product, which is convenient for manufacturing. The structure of the support part 12 can greatly improve the pressure bearing capacity of the entire snowboard while slightly increasing the consumption of fiber materials, thereby improving the cost performance. The setting of the edge reinforcement strip 13 can increase the thickness of the fiber layer on both sides of the snowboard, thereby improving the strength of the two sides of the snowboard that are easily bumped.

[0060] Preferably, the one-piece snowboard of this embodiment, such as Figure 4 As shown, the width of the two ends of the support part 12 is greater than the middle width. This structural design can improve the bearing capacity of the two ends of the support part 12, so that the angles of the force on the two ends of the support part 12 are dispersed at various angles, so that the force on the support part 12 is uniform, and the strength of the structure is improved.

[0061] This embodiment provides a snowboard mold for manufacturing the above-mentioned one-piece snowboard, including:

[0062] an upper mold 4, the inner side of which is used to accommodate the first fiber layer 1;

[0063] a lower layer mold 5, the inner side of the lower layer mold 5 is used to accommodate the second fiber layer 2;

[0064] The upper mold 4 can be assembled with the lower mold 5 to form a molding area of ​​the snowboard inside. It also includes a filling part 6, which is detachably installed between the upper mold 4 and the lower mold 5. Figure 5As shown, the snowboard mold of this embodiment first forms the foam layer 3 inside, and after the upper mold 4 and the lower mold 5 are assembled, a filling part 6 is set inside, and then the foam material is filled, and the foam material fills the inside of the snowboard mold. Under the interval of the filling part 6, the foam material is divided into three parts, and the interval position of the foam material is to provide space for the setting of the support part 12. After the foam material is formed, the filling part 6 needs to be removed, and then the first fiber layer 1, the second fiber layer 2 and the foam layer 3 are integrally formed.

[0065] Based on the above ideal embodiments of this application, the relevant staff can make various changes and modifications without departing from the technical concept of this application through the above description. The technical scope of this application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
