Description

Technical Field

[0001] This utility model relates to a hot pressing device for carbon fiber prepreg, belonging to the field of carbon fiber technology. Background Technology

[0002] Carbon fiber prepreg is a semi-cured composite material intermediate product obtained by impregnating carbon fibers (such as carbon fiber tows, fabrics, etc.) in a resin matrix and processing them through certain processes. It is a key raw material for preparing high-performance carbon fiber composites. The need for hot pressing of carbon fiber prepreg is determined by its material properties and the molding principle of composite materials. The hot pressing process, through the synergistic effect of "heating" and "pressurization," promotes the flow of resin in the prepreg, impregnates the fibers, and completes the curing reaction, ultimately forming a dense composite material component with excellent performance.

[0003] Announcement No.: CN 220883081 U discloses a carbon fiber hot pressing molding structure, including a base, which is a rectangular frame. A downward pressing and pushing structure is provided on the base, connected to an upper mold. The center of the upper mold corresponds to the center of the base. A pair of sliding grooves are symmetrically opened on both sides of the center of the base. This utility model relates to the field of carbon fiber hot pressing technology. This carbon fiber hot pressing molding structure utilizes the downward pressing and pushing structure to drive the upper and lower molds to push each other, completing the stamping operation. The lower mold is limited by a limiting structure on the pair of sliding grooves, thus fixing its position. Simultaneously, a pair of sliding blocks are adjusted relative to each other using a coaxial reverse lead screw, thereby driving the limiting blocks to move relative to each other, achieving position limitation of the lower mold, facilitating the disassembly and assembly of the lower mold, and improving the overall ease of equipment replacement.

[0004] The above solution has the following shortcomings in practical use:

[0005] In actual use, the upper and lower molds are usually designed as a set, and when different molds are replaced, they are usually replaced together. However, the above solution is not convenient for replacing the upper mold. At the same time, when loading and unloading the lower mold, the arm is inserted between the upper and lower molds. Since there is no additional safety mechanism for the upper mold, the upper mold may suddenly drop unexpectedly, which is not safe enough. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a hot pressing device for carbon fiber prepreg, which facilitates the replacement of the upper and lower molds, and adds safety measures to the upper mold to reduce the risk of the upper mold falling unexpectedly.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A carbon fiber prepreg hot pressing device includes: a frame, a hydraulic cylinder mounted on the top of the frame, an mounting plate mounted on the output end of the hydraulic cylinder, an upper mold below the mounting plate, a lower mold below the upper mold, T-slots formed on the bottom of the mounting plate and the bottom inner wall of the frame, T-plates slidably connected to the T-slots mounted on the top of the upper mold and the bottom of the lower mold, a limiting T-block slidably mounted on one side of the T-slot and abutting against the T-plate, a limiting component for limiting the T-slot and the T-plate on the limiting T-block, and a safety component for improving the safety of loading and unloading the lower mold on the top of the frame.

[0009] Preferably, the limiting component includes two circular holes, which are respectively opened at both ends of one side of the limiting T-block. A pin is connected to the circular hole by a spring. Both ends of the T-slot are provided with insertion holes that are slidably connected to the pin. A sliding plate is installed on one side of the pin, and a sliding groove is provided on one side of the limiting T-block that is slidably connected to the sliding plate.

[0010] Preferably, the outer wall of the skateboard is provided with a rubber layer.

[0011] Preferably, the safety component includes an electric cylinder mounted on the top of the frame. A connecting plate is mounted on the output end of the electric cylinder. A slide rod that is slidably connected to the frame is mounted below one end of the connecting plate. A plug is mounted on one end of the slide rod. A slot for insertion into the plug is provided on one end of the mounting plate.

[0012] Preferably, guide rods that are slidably connected to the frame are installed on both sides of the top of the mounting plate.

[0013] Preferably, a PLC controller is provided at one end of the frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The upper and lower molds are installed on the mounting plate and frame respectively by the T-plate and T-slot. The T-plate is then limited by the T-block sliding into the T-slot. Finally, the T-block is fixed by the limiting component, which fixes the upper and lower molds and improves their stability. When replacement is needed, the slide plate is pulled to slide in the groove and drive the pin away from the plug block. The T-block can then be removed to take out the upper and lower molds for replacement.

[0016] 2. When loading and unloading the lower mold, the electric cylinder can be activated. The electric cylinder drives the connecting plate to extend, causing the slide rod to drive the insert block into the slot, which limits the mounting plate. This adds extra safety to the upper mold, reduces the possibility of the upper mold falling unexpectedly, and protects the operator's arms. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] Please see Figs. 1-3 This utility model provides a technical solution:

[0024] A carbon fiber prepreg hot pressing device includes: a frame 1, a hydraulic cylinder 2 mounted on the top of the frame 1, an mounting plate 3 mounted on the output end of the hydraulic cylinder 2, an upper mold 4 below the mounting plate 3, a lower mold 5 below the upper mold 4, T-slots 6 being formed on the bottom of the mounting plate 3 and the bottom inner wall of the frame 1, T-plates 7 being slidably connected to the T-slots 6 being mounted on the top of the upper mold 4 and the bottom of the lower mold 5, a limiting T-block 8 being slidably mounted on one side of the T-slot 6 and abutting against the T-plate 7, a limiting component 9 being provided on the limiting T-block 8 to limit the T-slot 6 and the T-plate 7, and a safety component 10 being provided on the top of the frame 1 to improve the safety of loading and unloading the lower mold 5.

[0025] Furthermore, after the two T-shaped plates 7 are inserted into the two T-shaped grooves 6 respectively, after one side of the T-shaped plate 7 abuts against one side of the T-shaped groove 6, there is still a certain space on the other side of the T-shaped groove 6, so that the limiting T-shaped block 8 can be inserted into the T-shaped groove 6. The limiting T-shaped block 8 abuts against the other side of the T-shaped plate 7, so that the T-shaped plate 7 can be limited in the T-shaped groove.

[0026] In this embodiment: the limiting component 9 includes two round holes 901, which are respectively opened at both ends of one side of the limiting T-block 8. A pin 903 is connected to the round hole 901 by a spring 902. Both ends of the T-slot 6 are provided with insertion holes 904 that are slidably connected to the pin 903. A sliding plate 905 is installed on one side of the pin 903. A sliding groove 906 that is slidably connected to the sliding plate 905 is provided on one side of the limiting T-block 8.

[0027] Furthermore, press the two sliding plates 905 to allow the pin 903 to enter the round hole 901 and compress the spring 902. Then slide the limiting T-block 8 into the T-groove 6. After the limiting T-block 8 presses against the T-plate 7, release the sliding plates 905. The restoring force of the spring 902 causes the pin 903 to enter the insertion hole 904, fixing the limiting T-block 8 and the T-groove 6. This fixes the T-plate 7 and improves the stability of the upper mold 4 and the lower mold 5.

[0028] In this embodiment: the outer wall of the slide plate 905 is provided with a rubber layer.

[0029] Furthermore, the rubber layer improves the comfort of staff handling the 905 skateboard with their fingers.

[0030] In this embodiment: the safety component 10 includes an electric cylinder 101, which is mounted on the top of the frame 1. A connecting plate 102 is mounted on the output end of the electric cylinder 101. A slide rod 103 that is slidably connected to the frame 1 is mounted below one end of the connecting plate 102. An insert block 104 is mounted on one end of the slide rod 103. A slot 105 for inserting into the insert block 104 is opened on one end of the mounting plate 3.

[0031] Furthermore, during the loading and unloading process, the electric cylinder 101 can be activated to move the connecting plate 102, causing the slide rod 103 to drive the insert block 104 into the slot 105, thereby limiting the mounting plate 3 and preventing the mounting plate 3 from accidentally falling and causing injury to the worker's arm.

[0032] In this embodiment: guide rods that are slidably connected to the frame 1 are installed on both sides of the top of the mounting plate 3.

[0033] Furthermore, the lifting and lowering of the mounting plate 3 causes the guide rod to slide on the frame 1, which can improve the stability of the mounting plate 3.

[0034] In this embodiment: A PLC controller is provided at one end of the frame 1.

[0035] Furthermore, the PLC controller and the electrical components used in this device are linearly connected, making it convenient for operators to control.

[0036] The workflow of this embodiment is as follows: Carbon fiber prepreg is placed in the lower mold 5. Hydraulic cylinder 2 is activated to lower the mounting plate 3, causing the upper mold 4 to descend for hot pressing. Then, hydraulic cylinder 2 raises the mounting plate 3, causing the upper mold 4 to rise. The operator can then remove the prepreg formed in the lower mold 5. During loading and unloading, electric cylinder 101 can be activated to move the connecting plate 102, causing the slide rod 103 to move the insert block 104 into the slot 105, limiting the mounting plate 3 and preventing accidental descent that could injure the operator's arm. When the upper mold 4 and lower mold 5 need to be replaced, the operator presses the two sliding plates 905 with their fingers, bringing them closer together. The sliding plates 905 drive the pin 903 into the round hole 901 while simultaneously compressing the spring 902. After the pin 903 leaves the insertion hole 904, the operator... Pulling the sliding plate 905 will disengage the limiting T-block 8 from the T-slot 6. Then, the operator can pull the upper mold 4 and lower mold 5 to slide the T-plate 7 out of the T-slot 6, allowing the upper mold 4 and lower mold 5 to be removed. The upper mold 4 and T-plate 7, and the lower mold 5 and T-plate 7 can then be replaced as a whole. During installation, the T-plate 7 is aligned with the T-slot 6 and slid into it. After the upper mold 4 and lower mold 5 are installed, the two sliding plates 905 are pressed down to allow the pin 903 to enter the round hole 901 and compress the spring 902. Then, the limiting T-block 8 is slid into the T-slot 6. After the limiting T-block 8 presses against the T-plate 7, the sliding plate 905 is released. The restoring force of the spring 902 allows the pin 903 to enter the insertion hole 904, fixing the limiting T-block 8 and the T-slot 6. This fixes the T-plate 7 and improves the stability of the upper mold 4 and lower mold 5.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
