Description

Technical Field

[0001] This utility model relates to the field of composite material molding technology, and more specifically, to a composite material molding press. Background Technology

[0002] In the daily production process of composite materials, molding presses are often used. Molding presses extrude composite materials into molds of different sizes through pressure. They are easy to use, have high molding efficiency, and are widely used in various object molding applications.

[0003] When composite materials need to be molded, they are usually pressed together using a mold. However, due to insufficient pressure from the mold, it is difficult to form a satisfactory composite material model, which in turn affects the efficiency of composite material molding and the quality of the output. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a composite material molding press that can increase the pressing force on the mold to improve the full molding of composite materials, thereby improving the quality of the composite material output.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a composite material molding press, including a frame, an upper pressure plate provided on the frame, a mold provided on the upper pressure plate, a lower pressure plate provided on the frame corresponding to the position of the upper pressure plate, a driving mechanism provided on the frame for driving the lower pressure plate to press the mold and move closer to the upper pressure plate, a limiting plate fixedly connected to one end of the driving mechanism near the lower pressure plate, and a slidably connected end of the limiting plate near the frame, the diameter of the limiting plate being larger than the diameter of the lower pressure plate.

[0006] By adopting the above technical solution, the raw material of the composite material to be processed is placed into the mold of the upper pressure plate, which corresponds to the position of the lower pressure plate. The operator then drives the limiting plate and the lower pressure plate to move and press down towards the upper pressure plate and the mold through the action of the drive mechanism. The drive mechanism drives the lower pressure plate to exert a certain downward pressure, while the limiting plate moves along the surface of the frame to move and press down on the position of the limiting plate and the lower pressure plate connected to it. When the lower pressure plate corresponds to the position of the mold and presses down on the raw material in the mold to form it, the downward pressure of the drive mechanism is removed after a period of forming. Then the lower pressure plate will move away from the mold and the upper pressure plate, and the composite material will be formed in the mold. This can improve the efficiency and effect of composite material forming. Moreover, the downward pressure of the lower pressure plate is relatively stable, ensuring the stability of the composite material forming in the mold, thereby improving the quality of the composite material output.

[0007] The present invention is further configured such that the driving mechanism includes a cylinder disposed between the frame and the limiting plate.

[0008] By adopting the above technical solution, the cylinder can improve the efficiency of the limiting plate and the lower pressure plate approaching the upper pressure plate and the mold, increase the efficiency of the composite material forming in the mold, and increase the downward pressure on the composite material. This not only improves the efficiency and quantity of composite material production, but also improves the efficiency and effect of composite material output.

[0009] The present invention is further configured such that the driving mechanism includes a hydraulic cylinder disposed between the frame and the limiting plate.

[0010] By adopting the above technical solution, the hydraulic cylinder not only stably drives the lower pressure plate close to the upper pressure plate and the mold on the upper pressure plate, but also increases the downward driving force of the lower pressure plate, thereby increasing the downward pressing force of the lower pressure plate to improve the molding effect of composite materials, and thus improving the quality of the composite material output.

[0011] The present invention is further configured such that: a limiting block is provided at one end of the limiting plate near the frame, and a sliding groove is provided on the frame for the limiting block to slide.

[0012] By adopting the above technical solution, the limiting plate moves along the frame as the lower pressure plate is pressed down, and the limiting block of the limiting plate always moves along the slide groove opened in the frame. The movement position of the limiting plate is restricted to ensure the stability of the limiting plate and the lower pressure plate when they move. This ensures the stability and force when the lower pressure plate is close to the upper pressure plate, so that the composite material in the mold is subjected to stable pressure to achieve the molding effect and improve the quality of the composite material output.

[0013] The present invention is further configured such that the limiting block is T-shaped and fits tightly against the inner wall of the groove.

[0014] By adopting the above technical solution, the limiting block on the limiting plate will not easily detach from the slide groove when it slides along the slide groove, thereby ensuring that the limiting block and the lower pressure plate are more stable when sliding along the frame. This improves the stability and force of the lower pressure plate during the pressing process, thereby enhancing the pressing effect on the composite material in the mold and improving the quality of the composite material output.

[0015] The present invention is further configured such that: a ball protrudes from the limiting block, and a groove is provided on the inner wall of the slide for the ball to roll, and the ball is rotatably connected to the limiting block.

[0016] By adopting the above technical solution, when the limiting block moves, the ball will contact the inner wall of the groove and generate friction with the inner wall of the groove, thus rotating on the limiting block. This reduces the friction between the limiting block and the inner wall of the groove due to the rotation of the ball, and the ball is always confined within the groove, thereby improving the efficiency of the limiting block and the limiting plate moving on the frame.

[0017] The present invention is further configured such that: the mold includes an upper mold and a lower mold, the upper mold is disposed on a lower pressure plate, and the lower mold is disposed on an upper pressure plate.

[0018] By adopting the above technical solution, the upper mold and the lower mold are respectively set on the lower pressure plate and the upper pressure plate, so that the upper mold can press and shape the composite material in the lower mold fixed on the upper pressure plate by moving the lower pressure plate, and then remove the upper mold to realize the forming of the composite material in the lower mold.

[0019] The present invention is further configured such that: the lower mold is fixedly connected to the upper pressure plate by screws, the upper mold is fixedly connected to the lower pressure plate by screws, and the positions of the upper mold and the lower mold correspond to each other.

[0020] By adopting the above technical solution, both the upper and lower molds can be removed from the lower and upper pressure plates respectively using tools, enabling the replacement and maintenance of the upper and lower molds. This increases the efficiency and effect of composite material molding, expands the applicability of the molds, and allows the molding press to process composite materials of different sizes.

[0021] In summary, this utility model has the following beneficial effects: under the action of the driving mechanism, the lower pressure plate is driven to press down towards the upper pressure plate and the position corresponding to the mold, and the mold is pressed tightly to increase the pressing force on the mold, thereby improving the full molding of the composite material and thus improving the quality of the composite material output.

[0028] The present invention will now be described in detail with reference to the accompanying drawings.

[0029] A composite material molding press, as described above Figures 1-2 The system includes a frame 1, an upper pressure plate 4 on the frame 1, a mold on the upper pressure plate 4, a lower pressure plate 3 on the frame 1 corresponding to the position of the upper pressure plate 4, a drive mechanism 2 on the frame 1 for driving the lower pressure plate 3 to press the mold and move it close to the upper pressure plate 4, a limit plate 6 is fixedly connected to one end of the drive mechanism 2 near the lower pressure plate 3, and the limit plate 6 is slidably connected to the frame 1 at one end near the frame 1, the diameter of the limit plate 6 being larger than the diameter of the lower pressure plate 3.

[0030] A limiting block 8 is provided at one end of the limiting plate 6 near the frame 1. A sliding groove 10 is provided on the frame 1 for the limiting block 8 to slide. The limiting block 8 is T-shaped and fits tightly against the inner wall of the sliding groove 10.

[0031] A ball 9 is protruding from the limiting block 8, and a groove 11 is provided on the inner wall of the slide 10 for the ball 9 to roll. The ball 9 is rotatably connected to the limiting block 8.

[0032] The mold includes an upper mold 5 and a lower mold 7. The upper mold 5 is set on the lower pressure plate 3, and the lower mold 7 is set on the upper pressure plate 4. The lower mold 7 is fixedly connected to the upper pressure plate 4 by screws, and the upper mold 5 is fixedly connected to the lower pressure plate 3 by screws. The positions of the upper mold 5 and the lower mold 7 are corresponding.

[0033] Working principle: The raw material of the composite material to be processed is placed into the mold of the upper pressure plate 4, which corresponds to the position of the lower pressure plate 3. The operator then drives the limiting plate 6 and the lower pressure plate 3 to move and press down towards the upper pressure plate 4 and the mold under the action of the driving mechanism 2. The driving mechanism 2 drives the lower pressure plate 3 to exert a certain downward pressure. At the same time, the limiting plate 6 will move along the surface of the frame 1 to move and press down the position of the limiting plate 6 and the lower pressure plate 3 connected to it. When the lower pressure plate 3 corresponds to the position of the mold and presses down on the raw material in the mold to form it, after forming for a period of time, the downward pressure of the driving mechanism 2 is removed. Then the lower pressure plate 3 will move away from the mold and the upper pressure plate 4, and the composite material will be formed in the mold. This can improve the efficiency and effect of composite material forming. Moreover, the downward pressure of the lower pressure plate 3 is relatively stable, ensuring the stability of the composite material forming in the mold, thereby improving the quality of the composite material output.

[0034] As the lower pressure plate 3 is pressed down, the limiting plate 6 moves along the frame 1. Consequently, the limiting block 8 of the limiting plate 6 always moves along the slide groove 10 opened in the frame 1, restricting the movement of the limiting plate 6 to ensure the stability of the limiting plate 6 and the lower pressure plate 3 during movement. This ensures the stability and force of the lower pressure plate 3 when it presses down close to the upper pressure plate 4, so that the composite material in the mold is subjected to stable pressure to achieve the molding effect and improve the quality of the composite material output. When the limiting block 8 on the limiting plate 6 slides along the slide groove 10, it will not easily disengage from the slide groove 10. This ensures that the limiting block 8 and the lower pressure plate 3 are more stable when sliding along the frame 1, thus improving the stability and force of the lower pressure plate 3 during the pressing process, thereby improving the molding effect of the composite material in the mold and improving the quality of the composite material output.

[0035] When the limiting block 8 moves, the ball 9 will contact the inner wall of the groove 11 and rub against the inner wall of the groove 11, causing the limiting block 8 to rotate. This reduces the friction between the limiting block 8 and the inner wall of the groove 10 due to the rotation of the ball 9, and the ball 9 is always confined within the groove 11, thereby improving the efficiency of the limiting block 8 and the limiting plate 6 moving on the frame 1.

[0036] The upper mold 5 and the lower mold 7 are respectively set on the lower pressure plate 3 and the upper pressure plate 4, so that the upper mold 5 can press and shape the composite material in the lower mold 7 fixed on the upper pressure plate 4 by moving the lower pressure plate 3, and then remove the upper mold 5 to realize the forming of the composite material in the lower mold 7.

[0037] Both the upper mold 5 and the lower mold 7 can be removed from the lower pressure plate 3 and the upper pressure plate 4 respectively using tools, so as to replace and repair the upper mold 5 and the lower mold 7, thereby increasing the efficiency and effect of composite material molding, increasing the applicability of the mold, and enabling the molding press to process composite materials of different sizes.

[0038] Example 1: The drive mechanism 2 includes a cylinder disposed between the frame 1 and the limiting plate 6. The cylinder can improve the efficiency of the limiting plate 6 and the lower pressure plate 3 approaching the upper pressure plate 4 and the mold, increase the efficiency of the composite material forming in the mold, and increase the downward pressure on the composite material. This not only improves the efficiency and quantity of composite material production, but also improves the efficiency and effect of composite material output.

[0039] Example 2: Compared with Example 1, the difference in Example 2 is that the driving mechanism 2 includes a hydraulic cylinder disposed between the frame 1 and the limiting plate 6. The hydraulic cylinder not only stably drives the lower pressure plate 3 to approach the upper pressure plate 4 and the mold on the upper pressure plate 4, but also increases the downward driving force of the lower pressure plate 3, thereby increasing the downward force of the lower pressure plate 3 to improve the molding effect of the composite material, and thus improving the quality of the composite material produced.

[0040] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
