Description

Technical Field

[0001] This utility model belongs to the field of carbon fiber product manufacturing technology, and in particular relates to a rapid prototyping tool for carbon fiber products. Background Technology

[0002] Carbon fiber products are composite materials made from carbon fiber prepreg as the core raw material through molding, hot pressing, curing, and winding processes. These products utilize the high specific strength and low density of carbon fiber and are widely used in aerospace, rail transportation, sporting goods, medical equipment, consumer electronics, and new energy vehicles. Furthermore, the production of carbon fiber products requires the use of molds.

[0003] However, in actual use, traditional molding processes rely on equipment such as autoclaves to provide a high-temperature and high-pressure environment and to cure the prepreg through vacuum sealing and other methods, which also takes up mold usage time. Utility Model Content

[0004] The purpose of this utility model is to provide a rapid prototyping tooling for carbon fiber products in order to solve the problem of low efficiency caused by the long time traditional molds occupy the mold.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a rapid prototyping tooling for carbon fiber products, including a mold base, a front mold connected to one side of the mold base, and further comprising: The right mold is connected to the top of the mold base on one side, and also connected to the front mold on one side. The left mold is connected to the top of the mold base on one side and to the front mold on one side, and the left mold is located on the right mold side; The silicone airbag is located at the top of the mold, and its two sides are respectively attached to the opposite side of the left and right molds, so that the silicone airbag inflates and compresses the carbon fiber product.

[0006] As a further description of the above technical solution: The top of the right mold and the top of the left mold are fitted with a lifting mold top cover, and the bottom of the mold top cover is fitted with one side of the front mold.

[0007] As a further description of the above technical solution: The mold base is connected to the lower tail mold on one side relative to the front mold, and one side of the lower tail mold is connected to one side of the left mold and one side of the right mold respectively.

[0008] As a further description of the above technical solution: The upper tail mold is connected to the top of the lower tail mold, and one side of the upper tail mold is connected to one side of the mold top cover. The upper tail mold is also connected to one side of the right mold and one side of the left mold.

[0009] As a further description of the above technical solution: A through hole is provided between the upper tail mold and the lower tail mold, and the air inlet of the silicone airbag extends out of the upper tail mold and the lower tail mold through the through hole.

[0010] As a further description of the above technical solution: The surface of the silicone airbag is coated with a prepreg, and the carbon fiber is demolded by the prepreg separation function.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, after the carbon fiber product has cured, the silicone airbag is deflated, and then the silicone airbag is contracted and removed from the product, so that the carbon fiber product remains in the mold. This ensures that the mold is only used during the curing process, and the mold can be kept in the press at the rest of the time to maintain the temperature. This greatly reduces the time occupied by the mold and the time used by the equipment during the laying and curing of the carbon fiber product.

[0012] 2. In this utility model, by setting up a silicone airbag, coating the surface of the silicone airbag with prepreg, and then connecting it to an air machine, the silicone airbag is inflated and expanded, thereby creating pressure between the silicone airbag and the external mold to compact, distribute, and fix the composite material, without the need for external pressure equipment, thus ensuring the material is dense.

[0015] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-3 This utility model provides a technical solution: a rapid prototyping tooling for carbon fiber products, including a mold base 6, a front mold 2 connected to one side of the mold base 6, and further including: The right mold 5 is connected to the top of the mold base 6 on one side, and the right mold 5 is also connected to the front mold 2 on one side. The left mold 7 is connected to the top of the mold base 6 on one side and to the front mold 2 on one side on the other side. The left mold 7 is located on the right mold 5. The silicone airbag 8 is located at the top of the mold, and its two sides are respectively attached to the opposite sides of the left mold 7 and the right mold 5, so that the silicone airbag 8 inflates and compresses the carbon fiber product. The top of the right mold 5 and the top of the left mold 7 are attached to the top of the mold cover 1, and the bottom of the mold cover 1 is attached to one side of the front mold 2. The mold base 6 is connected to the lower tail mold 4 on the side opposite to the front mold 2, and one side of the lower tail mold 4 is connected to one side of the left mold 7 and the right mold 5. The top of the lower tail mold 4 is connected to the upper tail mold 3, and one side of the upper tail mold 3 is connected to one side of the mold cover 1, and one side of the upper tail mold 3 is connected to one side of the right mold 5 and the left mold 7. There is a through hole between the upper tail mold 3 and the lower tail mold 4, and the air inlet of the silicone airbag 8 extends out of the upper tail mold 3 and the lower tail mold 4 through the through hole. The surface of the silicone airbag 8 is coated with prepreg liquid, and the carbon fiber is demolded by the prepreg liquid separation function.

[0017] In a specific implementation, after the carbon fiber product is cured in the mold, the silicone airbag 8 is deflated, causing it to shrink. The deflated silicone airbag 8 is then removed from the product, leaving the carbon fiber product in the mold. This allows the mold to be used only during the curing process, while the mold remains in the press at the rest of the time to maintain the temperature. This reduces the time the carbon fiber product occupies the mold and the equipment usage time during the laying and curing process, thereby improving the efficiency of the device. Furthermore, by setting up a silicone airbag 8 and coating its surface with prepreg, the carbon fiber product can be easily separated from the silicone airbag 8. Then, the silicone airbag 8 is connected to an air blower through a hose, and the air blower is started to inflate the silicone airbag 8. This creates pressure between the silicone airbag 8 and the external mold, which compacts, distributes, and fixes the carbon fiber composite material, eliminating the need for external pressure equipment and ensuring the material is dense.

[0018] Working principle: In use, prepreg is applied to the surface of the silicone airbag 8, and then carbon fiber fabric is attached to the surface of the silicone airbag 8. The right mold 5 and the left mold 7 are then installed together, and the top cover 1 of the mold is fixed. The air inlet at one end of the silicone airbag 8 extends between the upper tail mold 3 and the lower tail mold 4. Then, by connecting an air blower, the air blower blows air onto the silicone airbag 8, causing the silicone airbag 8 to expand. The silicone airbag 8 then compresses the carbon fiber product, making the carbon fiber product more compact due to compression, thus ensuring the production quality of the carbon fiber product.
