Description

Technical Field

[0001] This utility model relates to the field of carbon fiber sheet forming mold technology, and in particular to a high-precision carbon fiber sheet forming mold. Background Technology

[0002] A carbon fiber sheet molding die is a special tool used to manufacture carbon fiber sheets. It is formed by curing carbon fiber prepreg or carbon fiber cloth with resin and other materials under high temperature and high pressure conditions, thereby forming a carbon fiber sheet with a certain shape and properties.

[0003] The traditional shaping process first involves placing the molding die and the material to be shaped into a sealed vacuum chamber. A vacuum pump is then used to extract the air from the chamber, reducing the internal pressure and creating a vacuum environment. However, during operation, the mold needs to be placed in a vacuum bag, and the air in the bag is then extracted. The vacuum bag is then sealed with sealing tape, and the carbon fiber sheet is shaped under vacuum. These operations are not only time-consuming but also require a high level of skill from the operators. Slight mistakes can lead to incomplete sealing or uneven material distribution, thus affecting the quality of the final product.

[0004] Therefore, this utility model provides a high-precision carbon fiber sheet forming mold. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a high-precision carbon fiber sheet molding die.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-precision carbon fiber sheet forming mold, comprising; The bottom module has a shaping cavity inside; A pushing component; the pushing component includes a movable module plate rotatably connected to the top of the bottom module, and both ends of the inner wall of the movable module plate are provided with sliding grooves, a slider is slidably connected to the sliding groove, and a push plate is fixedly connected to the end of the slider away from the sliding groove. Negative pressure assembly; the negative pressure assembly includes a mounting base fixedly connected to the inner wall of the moving module plate, a negative pressure pump installed at the top of the mounting base, an air blowing pipe fixedly connected to the output end of the negative pressure pump, an air suction pipe fixedly connected to the input end of the negative pressure pump, and an air box fixedly connected to one side of the bottom module. Positioning assembly; the positioning assembly includes a rotating shaft fixedly connected to both ends of the air box, a rotating block rotatably connected to the outer side of the rotating shaft, a locking plate slidably connected inside the rotating block, and a threaded rotating column rotatably connected inside the locking plate.

[0007] Preferably, a pressure plate is fixedly connected to the bottom end of the push plate, and both sides of the push plate and the pressure plate are slidably connected to the inside of the moving module plate.

[0008] Preferably, the bottom module has an air intake hole inside.

[0009] Preferably, one end of the air chamber is connected to the air intake port, and the other end of the air chamber is connected to the air intake pipe.

[0010] Preferably, the outer sides of both the blowing pipe and the suction pipe are fixedly connected to the inside of the moving module plate.

[0011] Preferably, the outer side of the threaded rotating column is threaded onto the rotating block, and the bottom end of the clamping plate contacts the top end of the moving module plate.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention, by activating the negative pressure pump, draws out air from the molding cavity, creating negative pressure. The air blowing pipe guides the air into the interior of the moving module plate, pushing the push plate downwards. The downward movement of the push plate causes the slider to slide along the groove, and the slider generates a uniform extrusion force through the pressure plate. This design, through the rotation of the rotating shaft driving the threaded column, and the cooperation of the clamping plate and the rotating block, ensures that the moving module plate and the bottom module surface are tightly fitted. Secondly, the air blowing in pushes the push plate downwards, generating uniform extrusion force, ensuring that the carbon fiber sheet is subjected to uniform force within the mold, avoiding uneven material laying, ensuring molding quality, making operation simpler, reducing the skill requirements for operators, and reducing errors caused by improper operation.

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a high-precision carbon fiber sheet forming mold, comprising; Bottom module 1, with a shaping cavity 2 inside; Pushing component 3; Pushing component 3 includes a moving module plate 31 rotatably connected to the top of the bottom module 1. Both ends of the inner wall of the moving module plate 31 are provided with sliding grooves 32. A slider 33 is slidably connected to the sliding grooves 32. A push plate 34 is fixedly connected to the end of the slider 33 away from the sliding grooves 32. A pressure plate 35 is fixedly connected to the bottom end of the push plate 34. Both sides of the push plate 34 and the pressure plate 35 are slidably connected to the inside of the moving module plate 31. The bottom module 1 serves as the foundation of the entire mold, providing support and positioning to ensure mold stability and molding accuracy. The shaping cavity 2 is used to place the prepreg of the carbon fiber sheet and provides the required shape and size during the molding process. The moving module plate 31, as the main part of the pushing component 3, carries and supports other components and realizes connection and relative movement with the bottom module 1. The slide groove 32 provides a sliding track for the slider 33, allowing it to slide smoothly within the moving module plate 31. The slider 33 connects the push plate 34 and the moving module plate 31, and the movement of the push plate 34 is realized by sliding within the slide groove 32. The push plate 34 directly contacts the carbon fiber sheet, applying pressure to shape it within the shaping cavity 2. The design of the push plate 34 enables the pressure applied to the carbon fiber sheet to be evenly distributed, avoiding molding defects caused by excessive or insufficient local pressure. The pressure plate 35 connects the push plate 34 and the moving module plate 31, providing support and positioning for the push plate 34 and assisting in applying pressure. like Figure 1 - Figure 4As shown, the negative pressure component 4 includes a mounting base 41 fixedly connected to the inner wall of the moving module plate 31. A negative pressure pump 42 is installed at the top of the mounting base 41. An air blowing pipe 43 is fixedly connected to the output end of the negative pressure pump 42. An air suction pipe 44 is fixedly connected to the input end of the negative pressure pump 42. An air box 45 is fixedly connected to one side of the bottom module 1. An air suction hole 46 is opened inside the bottom module 1. One end of the air box 45 is connected to the air suction hole 46, and the other end of the air box 45 is connected to the air suction pipe 44. The outer sides of the air blowing pipe 43 and the air suction pipe 44 are both fixedly connected to the inside of the moving module plate 31. Mounting base 41 is used to fix negative pressure pump 42 so that it can be stably installed on the inner wall of moving module plate 31. Negative pressure pump 42 creates negative and positive pressure environments in the mold by suction and blowing air, providing the required air pressure conditions for the molding of carbon fiber sheet. Blowing pipe 43 delivers positive pressure gas generated by negative pressure pump 42 into the mold to break the negative pressure environment or to blow air into the carbon fiber sheet. Suction pipe 44 draws gas from the mold into negative pressure pump 42 to form a negative pressure environment or to extract gas from carbon fiber sheet. Air box 45 serves as a gas storage and buffer device, connecting suction hole 46 and suction pipe 44 to ensure stable gas flow. Suction hole 46 is opened inside bottom module 1 to draw gas from the mold into air box 45, and then delivers it to negative pressure pump 42 through suction pipe 44. like Figure 1 - Figure 4 As shown, the positioning component 5 includes a rotating shaft 51 fixedly connected to both ends of the air box 45. A rotating block 52 is rotatably connected to the outer side of the rotating shaft 51. A locking plate 53 is slidably connected inside the rotating block 52. The bottom end of the locking plate 53 contacts the top end of the moving module plate 31. A threaded rotating column 54 is rotatably connected inside the locking plate 53. The outer side of the threaded rotating column 54 is threadedly connected to the rotating block 52. The rotating shaft 51 is fixedly connected to both ends of the air box 45 to support and connect the rotating block 52, allowing it to rotate around the rotating shaft 51. The rotating block 52 is rotatably connected to the outside of the rotating shaft 51, and a clamping plate 53 is slidably connected inside to realize the rotation and positioning of the clamping plate 53. The clamping plate 53 is slidably connected inside the rotating block 52, and its bottom end contacts the top end of the moving module plate 31 to position and fix the moving module plate 31. The threaded rotating column 54 is rotatably connected inside the clamping plate 53, and its outer side is threadedly connected to the rotating block 52 to adjust the position and pressure of the clamping plate 53. Through the threaded connection of the threaded rotating column 54, the pressure of the clamping plate 53 on the moving module plate 31 can be precisely controlled to ensure the stability of the positioning.

[0017] Working principle: like Figure 1 - Figure 4 As shown: In use: First, the moving module plate 31 is rotated to the top of the bottom module 1 and fits tightly against the surface of the bottom module 1. Then, the rotating block 52 is rotated, and the rotating shaft 51 drives the rotating threaded column 54 to rotate, so that the clamping plate 53 and the rotating block 52 cooperate with each other, and finally achieve a tight fit with the surface of the moving module plate 31. Once the moving module plate 31 is connected with the bottom module 1 and the rotating block 52, the negative pressure pump 42 is started, and the air in the shaping cavity 2 is sucked out through the air suction hole 46 to generate negative pressure. At this time, the air suction pipe 44 guides the negative pressure air to the air blowing pipe 43. During this process, the air blowing pipe 43 blows air into the interior of the moving module plate 31. The blown air pushes the push plate 34 downward under the action of pressure. The downward movement of the push plate 34 further drives the slider 33 to slide along the slide groove 32. The slider 33 is connected to the pressure plate 35. By sliding, the pressure plate 35 moves downward, and finally a squeezing effect is generated. This squeezing force uniformly presses the carbon fiber sheet, so that it is formed in the mold.

[0018] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
