Description

Technical Field

[0001] This utility model relates to the field of composite material molding technology, and in particular to a composite material molding apparatus. Background Technology

[0002] Composite material molding is a process that uses a mold to pressurize and heat (or at room temperature) composite materials (such as resin-based composite materials, carbon / glass fiber reinforced composite materials, etc.) into products of a specific shape. Molding is the "core bridge for the industrial application of composite materials." The essential function of composite material molding is to transform the "material advantages" of composite materials into "mass-producible, high-quality, and low-cost product advantages"—solving the efficiency and precision pain points of traditional processes and expanding the application boundaries of composite materials in the fields of automobiles, aerospace, electronics, and new energy. It is one of the most widely used and most industrialized processes in composite material molding.

[0003] Patent publication number "CN219650405U" discloses "a molding device for automotive composite materials," which includes a base. Mounting brackets are bolted to both sides of the base, and two hydraulic rods are fixedly connected to the top horizontal axis of the mounting brackets. The driving ends of the hydraulic rods penetrate the top horizontal axis of the mounting brackets and are fixedly connected to a molding plate for molding the automotive composite material. A limiting groove is provided at the top of the base, and a limiting plate is fixedly connected to the inner bottom wall of the limiting groove. Two identical support plates are welded to the top of the limiting plate. The sides of the limiting plate are slidably connected to the inner wall of the molding base, and multiple limiting blocks for supporting the limiting plate are welded to the inner wall of the molding base. This molding device for automotive composite materials eliminates the need for time-consuming installation and disassembly, enables automatic material unloading, thus not affecting the overall processing progress and reducing manual labor intensity.

[0004] After the device in the aforementioned patent is completed, the hydraulic rod is activated to drive the molding plate to reset. The molded automotive composite material will be ejected from the molding seat under the action of the ejector spring, thus realizing the unloading operation. If the ejection and unloading are achieved solely by the ejector spring, the elastic elongation of the spring is difficult to control precisely. This will not only cause the molding seat to be unable to stay stably in the preset position that facilitates part removal, but may also lead to problems such as incomplete ejection of the part or jamming in the mold cavity due to insufficient elasticity. This will result in difficulties in part removal, scratches or damage to the surface of the part, and have a significant negative impact on production efficiency and manufacturing costs. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the problems existing in the prior art, this utility model provides a molding apparatus for composite materials.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a molding device for composite materials, including an ejection mechanism, a vibration mechanism disposed above the ejection mechanism, and a molding mechanism disposed above the vibration mechanism;

[0009] The ejection mechanism includes a base and a servo electric cylinder. The top of the servo electric cylinder is fixedly installed on the bottom surface of the base. The output end of the servo electric cylinder is slidably connected through the bottom surface and the surface of the base. A lower mold is provided above the output end of the servo electric cylinder. An annular frame is fixedly installed on the bottom surface of the lower mold. The lower part of the annular frame is located above the output end of the servo electric cylinder.

[0010] By adopting the above technical solution and using a servo electric cylinder to push the mold out, the ejection stroke and speed can be precisely controlled. This not only makes part removal convenient and efficient, but also significantly reduces the risk of part damage, providing a reliable guarantee for production stability and part quality. It solves the problem that if only the ejector spring is used for ejection and unloading, the elastic elongation of the spring is difficult to control precisely. This not only causes the mold base to be unable to stay stably in the preset position for easy part removal, but may also cause incomplete part ejection or jamming in the mold cavity due to insufficient elasticity.

[0011] As a preferred embodiment of the composite material molding device of the present invention, the vibration mechanism includes an outer frame and a vibration motor. The connecting end of the vibration motor is fixedly installed on one side surface of the outer frame. The base surface of the ejection mechanism is provided with slots that penetrate the interior. Springs are fixedly installed on the bottom wall of the slots, and the top ends of the springs are fixedly installed on the bottom surface of the outer frame.

[0012] By adopting the above technical solution, after the composite material to be molded is transported to the lower mold of the ejection mechanism, the composite material can be vibrated and evenly spread in the mold by means of the synergistic action of the vibration motor and the spring, reducing internal pores, improving the fit between the material and the mold, effectively ensuring the consistency of material distribution, creating favorable conditions for the subsequent processing steps of the molding mechanism, and helping the process to proceed smoothly.

[0013] In a preferred embodiment of the compression molding device for composite materials described in this utility model, the bottom surface of the lower mold of the ejection mechanism is fixedly installed with limit blocks, the outer side of the lower mold is slidably connected to the inner side of the outer frame of the vibration mechanism, and the bottom ends of the limit blocks are respectively inserted into the bottom wall of the outer frame.

[0014] By adopting the above technical solution, limiting blocks are installed on the bottom surface of the lower mold and inserted into the bottom wall of the outer frame to provide basic limiting protection for the lower mold. At the same time, the outer side of the lower mold is slidably connected to the inner side of the outer frame to form a double limiting structure, which can effectively enhance the limiting stability, prevent the outer frame from causing the lower mold to shift under vibration conditions, and ensure the accuracy of equipment operation.

[0015] In a preferred embodiment of the composite material compression molding device of the present invention, the compression molding mechanism includes a support frame and a servo hydraulic cylinder. The top end of the servo hydraulic cylinder is fixedly installed on the top surface of the support frame, and the output end of the servo hydraulic cylinder is slidably connected through the top surface and the top wall of the support frame. An upper mold is fixedly installed on the output end of the servo hydraulic cylinder, and limit posts are fixedly installed on the top surface of the upper mold. The top ends of the limit posts are slidably connected through the top wall and the top surface of the support frame.

[0016] By adopting the above technical solution, the upper mold installed at the output end is pushed down by a servo hydraulic cylinder. The limit posts installed on the top surface of the upper mold slide through the top wall and top surface of the support frame, respectively, to provide reliable limit control for the upper mold, effectively avoid positional deviation during the downward movement, ensure the mold closing accuracy, and help subsequent processing to proceed stably.

[0017] In a preferred embodiment of the composite material compression molding device of the present invention, the bottom end of the support frame of the compression molding mechanism is fixedly installed on the base surface of the ejection mechanism, and the lower part of the upper mold is located above the lower mold.

[0018] By adopting the above technical solution, the base can provide stable fixing points for the surface-mounted support frame, ensuring the overall structural stability; the lowered upper mold and lower mold fit precisely together, achieving a reliable molding effect and laying a solid foundation for subsequent processing.

[0019] In a preferred embodiment of the composite material compression molding device of the present invention, a control panel is fixedly installed on one side surface of the support frame of the compression molding mechanism, and the control panel is electrically connected to the servo electric cylinder, the vibration motor of the vibration mechanism, and the servo hydraulic cylinder of the compression molding mechanism.

[0020] By adopting the above technical solution, a control panel installed on one side of the support frame is electrically connected to the servo electric cylinder, the vibration motor of the vibration mechanism, and the servo hydraulic cylinder of the molding mechanism. This allows for precise control commands to be issued, enabling independent regulation of the operating status of the two types of actuators. This ensures that each process is completed stably according to preset parameters, guaranteeing the accuracy and coordination of the overall equipment operation.

[0021] (III) Beneficial Effects

[0022] This invention provides a compression molding apparatus for composite materials. It has the following beneficial effects:

[0023] 1. By adding an ejection mechanism and using a servo electric cylinder to push the mold out, the ejection stroke and speed can be precisely controlled. This not only makes part removal convenient and efficient, but also significantly reduces the risk of part damage, providing a reliable guarantee for production stability and part quality. It solves the problem that if only the ejector spring is used for ejection and unloading, the elastic elongation of the spring is difficult to control precisely. This not only causes the mold base to be unable to stay stably in the preset position for easy part removal, but may also cause incomplete part ejection or jamming in the mold cavity due to insufficient elasticity.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0032] Example 1

[0033] Reference Figures 1 to 4 This is the first embodiment of the present invention. This embodiment provides a molding device for composite materials, including an ejection mechanism 1, a vibration mechanism 2 disposed above the ejection mechanism 1, and a molding mechanism 3 disposed above the vibration mechanism 2.

[0034] The ejection mechanism 1 includes a base 11 and a servo electric cylinder 12. The top of the servo electric cylinder 12 is fixedly installed on the bottom surface of the base 11. The output end of the servo electric cylinder 12 is slidably connected through the bottom and surface of the base 11. A lower mold 13 is provided above the output end of the servo electric cylinder 12. An annular frame 14 is fixedly installed on the bottom surface of the lower mold 13. The lower part of the annular frame 14 is located above the output end of the servo electric cylinder 12.

[0035] Specifically, the vibration mechanism 2 includes an outer frame 21 and a vibration motor 22. The connection end of the vibration motor 22 is fixedly installed on one side surface of the outer frame 21. The base 11 of the ejection mechanism 1 has slots 23 that penetrate the interior. Springs 24 are fixedly installed on the bottom wall of the slots 23. The tops of the springs 24 are fixedly installed on the bottom surface of the outer frame 21. Limiting blocks 5 are fixedly installed on the bottom surface of the lower mold 13 of the ejection mechanism 1. The outer side of the lower mold 13 is slidably connected to the inner side of the outer frame 21 of the vibration mechanism 2. The bottom ends of the limiting blocks 5 are inserted into the bottom wall of the outer frame 21.

[0036] Furthermore, the ejection mechanism 1 uses a servo electric cylinder 12 installed on the bottom surface of the base 11 to push the lower mold 13 out from the inner side of the outer frame 21 of the vibration mechanism 2. This allows for precise control of the ejection stroke and speed, making it not only convenient and efficient to pick up parts, but also significantly reducing the risk of damage to the parts. This provides a reliable guarantee for production stability and part quality. The annular frame 14 installed on the bottom surface of the lower mold 13 can effectively improve the limiting effect of the output end of the servo electric cylinder 12.

[0037] After the vibration mechanism 2 conveys the composite material to be molded to the lower mold 13 of the ejection mechanism 1, the lower mold 13, with the help of the vibration motor 22 installed on one side of the outer frame 21 and the springs 24 installed on the bottom, can vibrate the composite material to be evenly spread in the lower mold 13, reduce internal pores, improve the fit between the material and the mold, effectively ensure the consistency of material distribution, create good conditions for the subsequent processing steps of the molding mechanism 3, and help the process to proceed smoothly. The bottom ends of the springs 24 are respectively installed on the bottom wall of the slot 23, which is opened on the surface of the base 11 and penetrates through the interior.

[0038] Limiting blocks 5 are installed on the bottom surface of the lower mold 13 and are inserted into the bottom wall of the outer frame 21 to provide basic limiting protection for the lower mold 13. At the same time, the outer side of the lower mold 13 is slidably connected to the inner side of the outer frame 21 to form a double limiting structure, which can effectively enhance the limiting stability and prevent the outer frame 21 from causing the lower mold 13 to shift under vibration conditions, thus ensuring the accuracy of equipment operation.

[0039] Example 2

[0040] Reference Figures 1 to 4 This is the first embodiment of the present invention. Based on the previous embodiment, the molding mechanism 3 includes a support frame 31 and a servo hydraulic cylinder 32. The top end of the servo hydraulic cylinder 32 is fixedly installed on the top surface of the support frame 31. The output end of the servo hydraulic cylinder 32 is slidably connected through the top surface and the top wall of the support frame 31. An upper mold 33 is fixedly installed on the output end of the servo hydraulic cylinder 32. Limiting posts 34 are fixedly installed on the top surface of the upper mold 33. The top ends of the limiting posts 34 are slidably connected through the top wall and the top surface of the support frame 31. The bottom end of the support frame 31 of the molding mechanism 3 is fixedly installed on the surface of the base 11 of the ejection mechanism 1. The lower part of the upper mold 33 is located above the lower mold 13.

[0041] Specifically, a control panel 4 is fixedly installed on one side surface of the support frame 31 of the molding mechanism 3. The control panel 4 is electrically connected to the servo electric cylinder 12, the vibration motor 22 of the vibration mechanism 2, and the servo hydraulic cylinder 32 of the molding mechanism 3.

[0042] Furthermore, the molding mechanism 3 pushes the upper mold 33 mounted on the output end downward through the servo hydraulic cylinder 32 installed on the top of the support frame 31. The limiting posts 34 installed on the top surface of the upper mold 33 slide through the top wall and top surface of the support frame 31 respectively, providing reliable limit control for the upper mold 33, effectively avoiding positional deviation during the downward movement, ensuring the accuracy of mold closing, and facilitating the stable operation of subsequent processing. The base 11 can provide a stable fixing point for the support frame 31 mounted on the surface, ensuring the stability of the overall structure. The downward-moving upper mold 33 and lower mold 13 fit precisely, achieving a reliable molding effect and laying a solid foundation for subsequent processing.

[0043] The control panel 4, mounted on one side of the support frame 31, is electrically connected to the servo electric cylinder 12, the vibration motor 22 of the vibration mechanism 2, and the servo hydraulic cylinder 32 of the molding mechanism 3. It can accurately issue control commands to achieve independent control of the operating status of the two types of actuators, ensuring that each process is completed stably according to preset parameters, and guaranteeing the accuracy and coordination of the overall operation of the equipment.

[0044] Working principle: After the vibration mechanism 2 conveys the composite material to be molded to the lower mold 13 of the ejection mechanism 1, the vibration motor 22 on one side of the outer frame 21 and the bottom spring 24 work together to drive the lower mold 13 to vibrate, so that the material is evenly spread in the mold cavity, reducing internal pores and improving fit, ensuring consistent material distribution, and laying the foundation for subsequent processing. The bottom end of the spring 24 is installed on the bottom wall of the slot 23 that penetrates through the surface of the base 11, forming an elastic support structure.

[0045] In the molding mechanism 3, the servo hydraulic cylinder 32 at the top of the support frame 31 drives the upper mold 33 at the output end to move downward. The top of the limiting post 34 on the top surface of the upper mold 33 slides through the top wall and top surface of the support frame 31, providing reliable limiting and preventing displacement to ensure mold closing accuracy. The base 11 provides a stable fixing point for the support frame 31, ensuring the overall structure is stable. After the upper mold 33 and the lower mold 13 are precisely fitted together, reliable molding is achieved, creating conditions for subsequent steps.

[0046] The ejection mechanism 1 pushes the lower mold 13 out from the inside of the outer frame 21 via the servo electric cylinder 12 on the bottom surface of the base 11. This allows for precise control of the ejection stroke and speed, improving part removal efficiency and significantly reducing the risk of part damage. The annular frame 14 on the bottom surface of the lower mold 13 enhances the limiting effect on the output end of the servo electric cylinder 12, further ensuring ejection stability.

[0047] The limiting block 5 on the bottom surface of the lower mold 13 is inserted into the bottom wall of the outer frame 21. Combined with the sliding connection between its outer side and the inner side of the outer frame 21, a double limiting structure is formed, which effectively avoids positional displacement during vibration and ensures the accuracy of equipment operation.

[0048] A control panel 4, model PLC-200Smart, is installed on one side of the support frame 31. This panel is electrically connected to the servo electric cylinder 12, the vibration motor 22, and the servo hydraulic cylinder 32, respectively. It can accurately issue control commands and achieve independent control of the operating status of each actuator. By preset parameters, key indicators such as vibration frequency, molding pressure, and ejection speed can be coordinated to ensure that each process is completed stably according to standards, guaranteeing the accuracy and coordination of the overall equipment operation, and improving production efficiency and product quality stability.
