Description

Technical Field

[0001] This utility model relates to the technical field of badminton racket production equipment, specifically a carbon fiber badminton racket mold that facilitates material handling. Background Technology

[0002] In the field of carbon fiber badminton racket production, molds are the core equipment for achieving precise shaping of racket frames and shafts. Their performance is directly related to the product molding quality and production efficiency. Most existing carbon fiber badminton racket molds adopt traditional integrated or semi-open structures. After the carbon fiber prepreg is pressed and shaped, the mold groove fits tightly with the surface of the formed racket, and there is a lack of special demolding auxiliary design, which leads to obvious drawbacks in the demolding and material removal process.

[0003] Workers need to manually reach into the mold groove and remove the formed rackets by prying and pulling. This is not only laborious, but also prone to damaging the integrity of the carbon fiber material due to uneven force, resulting in defects in the finished product. At the same time, it takes a long time to remove material from a single racket, and the manual operation is inefficient. It is difficult to adapt to the capacity requirements of large-scale production, which restricts the continuity and economy of the overall production process. Utility Model Content

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a carbon fiber badminton racket mold that facilitates material handling.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a carbon fiber badminton racket mold for easy material handling, comprising a cover, a base frame, a base plate, and a bottom mold. The cover is located at the upper end of the base frame, the base frame is located above the base plate, the base frame is provided with a placement groove, the bottom mold is located inside the placement groove, and the edge of the bottom mold is provided with a mold groove. The bottom mold is fixed to the upper end of the base plate by a support rod. The lower end of the base frame is provided with multiple cavities. The upper end of the base plate is provided with multiple vertical rods inserted into the cavities. The top of the vertical rod is provided with a slider located inside the cavity. The slider is slidably connected to the cavity. The cavity is provided with a spring. The top of the spring is fixed to the top of the cavity, and the bottom of the spring is connected to the slider.

[0006] To facilitate the removal of the cover from the upper part of the base frame, the present invention includes the following improvements: multiple positioning blocks are provided at the four corners of the upper part of the base frame, and multiple positioning grooves that cooperate with the positioning blocks are provided at the four corners of the lower part of the cover. The positioning blocks are hemispherical structures, and the front end of both the cover and the base frame are provided with grooves.

[0007] To facilitate the repositioning of the base frame, the present invention includes the following improvements: the diameter of the slider is larger than the diameter of the vertical rod, and the circumference of the slider is in close contact with the inner wall of the cavity; multiple damping rings are fixedly installed at the lower end of the base frame and penetrated by the vertical rod, and there is frictional resistance between the damping rings and the vertical rod.

[0008] Furthermore, the present invention includes the following improvements: multiple limiting grooves are provided on both sides of the base frame, multiple side rods are vertically arranged on both sides of the base plate, the top of the side rods is provided with a limiting block that is inserted into the limiting groove and slidably connected with the limiting groove, an iron plate is inlaid at the bottom of the limiting groove, and a magnetic block that magnetically engages with the iron plate is inlaid at the lower end of the limiting block.

[0009] To facilitate assembly of the side rods, the present invention is improved by fixing the side rods to both sides of the base plate with screws.

[0010] (III) Beneficial Effects Compared with the prior art, this utility model provides a carbon fiber badminton racket mold that is easy to handle, and has the following beneficial effects: This application adopts a "movable base frame + spring drive" design, which allows the molded workpiece to be exposed from the mold cavity by pressing the base frame. The material can be picked up without contacting the workpiece surface, thus completely avoiding workpiece defects caused by uneven force application.

[0011] The bottom mold is fixed to the base plate by a support rod to ensure the precise position of the mold groove and avoid displacement during molding; the magnetic attraction between the magnetic block and the iron plate makes it difficult for the base frame to shift when the mold is placed, and also prevents the base frame from "repeatedly jumping" when the spring returns to its original position, ensuring the flush accuracy between the base frame and the bottom mold in the initial state and guaranteeing the molding quality of the carbon fiber badminton racket.

[0013] 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.

[0014] Please see Figures 1-5 A carbon fiber badminton racket mold for easy material handling includes a cover 1, a base frame 2, a base plate 3, and a bottom mold 6. The cover 1 is located at the upper end of the base frame 2, and the base frame 2 is located above the base plate 3. The base frame 2 is provided with a placement groove, and the bottom mold 6 is located inside the placement groove. The bottom mold 6 is provided with a mold groove 7 at its edge. The bottom mold 6 is fixed to the upper end of the base plate 3 by a support rod. The lower end of the base frame 2 is provided with multiple cavities 10. The upper end of the base plate 3 is provided with multiple vertical rods 9 inserted into the cavities 10. The top end of the vertical rods 9 is provided with a slider 11 located inside the cavity 10. The slider 11 is slidably connected to the cavity 10. The cavity 10 is provided with a spring 12. The top end of the spring 12 is fixed to the top of the cavity 10, and the bottom end of the spring 12 is connected to the slider 11.

[0015] The diameter of the slider 11 is larger than the diameter of the vertical rod 9, and the periphery of the slider 11 is tightly fitted with the inner wall of the cavity 10. The lower end of the base frame 2 is fixedly provided with a plurality of damping rings 13 that are penetrated by the vertical rod 9, and there is frictional resistance between the damping rings 13 and the vertical rod 9.

[0016] Workpiece positioning and mold pre-assembly: The carbon fiber semi-finished workpiece is placed smoothly into the mold groove 7 on the edge of the bottom mold 6. The bottom mold 6 is firmly connected to the upper end of the base plate 3 by the support rod and is embedded in the placement groove inside the base frame 2. At this time, the upper surface of the base frame 2 is flush with the upper surface of the bottom mold 6, laying the foundation for the subsequent shaping process.

[0017] The base frame 2 has multiple limiting grooves 15 on both sides, and multiple side rods 14 are vertically arranged on both sides of the base plate 3. The top of the side rod 14 is provided with a limiting block 16 that is inserted into the limiting groove 15 and slidably connected with the limiting groove 15. An iron plate 18 is embedded at the bottom of the limiting groove 15, and a magnetic block 17 that magnetically engages with the iron plate 18 is embedded at the lower end of the limiting block 16.

[0018] The side rods 14 are fixed to both sides of the base plate 3 by screws.

[0019] The side rods 14 on both sides of the base plate 3 are fixed with screws. The limiting block 16 at the top of the side rod 14 is precisely inserted into the limiting groove 15 on both sides of the base frame 2. The magnetic block 17 at the bottom of the limiting block 16 and the iron plate 18 at the bottom of the limiting groove 15 naturally magnetically attract each other, ensuring that the base frame 2 is stably placed in the initial state and avoiding displacement.

[0020] Cover 1 snaps in and seals securely: The base frame 2 has multiple positioning blocks 4 at its four corners, and the cover 1 has multiple positioning grooves 5 at its four corners that cooperate with the positioning blocks 4. The positioning blocks 4 are hemispherical structures, and the cover 1 and the front end of the base frame 2 are both provided with grooves 8.

[0021] The cover 1 is fastened to the upper end of the base frame 2, so that the hemispherical positioning blocks 4 at the four corners of the upper end of the base frame 2 are precisely embedded in the corresponding positioning grooves 5 at the four corners of the lower end of the cover 1. The cover 1 is tightly fixed by means of the friction between the positioning blocks 4 and the positioning grooves 5, which prevents the workpiece from shifting during heating and shaping. The cover 1 and the groove 8 at the front end of the base frame 2 are in a ready-to-operate state at this time, providing a convenient force application point for subsequent mold disassembly.

[0022] Heat shaping process: The assembled mold (including cover 1, base frame 2, base plate 3, bottom mold 6 and workpiece) is transferred to the designated heating equipment. The carbon fiber workpiece is precisely shaped through the mold groove 7. During this process, the bottom mold 6 is kept in a stable position by the support rod to ensure the forming accuracy of the workpiece.

[0023] Demolding and material removal operation: After heating is complete, the mold is transferred to the workbench. The staff can easily pry open and remove the cover 1 by applying force through the groove 8 at the front end of the cover 1 and the base 2.

[0024] Then manually press down on the base frame 2 to overcome the magnetic attraction between the limiting block 16 and the iron plate 18, so that the limiting block 16 slides upward along the limiting groove 15 (the side rod 14 provides vertical guidance for the limiting block 16). At the same time, the vertical rod 9 at the upper end of the base plate 3 passes through the damping ring 13 at the lower end of the base frame 2. When the base frame 2 moves down, it drives the slider 11 at the top of the vertical rod 9 to slide upward along the cavity 10 inside the base frame 2, and the spring 12 inside the cavity 10 is compressed.

[0025] As the base frame 2 continues to move downward, the molded workpieces that were originally embedded in the mold groove 7 are gradually exposed, and the staff can directly pick up the materials by hand without prying or pulling, thus avoiding damage to the workpieces.

[0026] Mold reset preparation: After the material is picked up, the pressure on the base frame 2 is released, and the spring 12 in the cavity 10 releases its elastic force to achieve a reset, which drives the slider 11 to slide down along the cavity 10 to the bottom, thereby pulling the base frame 2 to move back up.

[0027] During this process, the frictional resistance between the damping ring 13 and the vertical rod 9 buffers the reset speed of the base frame 2, preventing violent shaking; At the same time, under the combined action of gravity and the magnetic attraction of the magnetic block 17, the limiting block 16 slides down to the bottom along the limiting groove 15. The magnetic block 17 and the iron plate 18 re-magnetically attach to each other, and finally the upper surface of the base frame 2 and the upper surface of the bottom mold 6 are restored to be flush. The mold returns to its initial state and is ready for the next processing.

[0028] Each component is designed around the principles of "easy operation" and "reliable structure": the placement slot provides a stable installation space for the bottom mold 6, the cooperation between the vertical rod 9 and the cavity 10 ensures the support strength of the base frame 2 when it moves, and the elastic force of the spring 12 not only assists the base frame 2 in resetting, but also prevents the base frame 2 from suddenly falling when picking up materials; the overall structure has no sharp protrusions, making the operation safer and adaptable to the stringent requirements of industrial-scale production.

[0029] Spring 12 Selection: Type selection: Cylindrical helical compression spring 12; Selection criteria: When the mold is working, the spring 12 needs to be compressed by pressing the base frame 2. After the material is removed, the spring 12 will drive the base frame 2 to return to its original position. The cylindrical spiral compression spring 12 can stably withstand axial pressure and has a simple structure that fits the installation space of the cavity 10 inside the base frame 2. It can be precisely matched with the slider 11 at the top of the vertical rod 9 (the slider 11 pushes the spring 12 to compress, and the spring 12 drives the slider 11 to drive the base frame 2 to return to its original position). Material selection: 60Si2Mn spring steel; Core advantages: High temperature resistance adapts to mold scenarios: After carbon fiber badminton rackets are heated and shaped, there is a certain degree of temperature conduction in the mold. 60Si2Mn spring steel can maintain elastic stability within 200℃ without significant attenuation, avoiding the failure of spring 12 due to high temperature. Damping ring 13 selection: High-temperature scenarios (mold working temperature 120-200℃): Fluororubber is selected, which can withstand temperatures up to 200℃ and has strong aging resistance. It is not easily deformed after long-term exposure to heat, making it suitable for working conditions where the mold temperature is high after heating.

[0030] Selection of Magnetic Block 17: Type selection: Embedded permanent magnet block (square or cylindrical); Selection criteria: The magnetic block 17 needs to be embedded in the lower end of the limiting block 16 at the top of the side rod 14 and magnetically engaged with the iron plate 18 at the bottom of the limiting groove 15. The square or cylindrical structure makes it easy to process the corresponding groove 8 in the limiting block 16 for embedding and fixing, and the magnetic surface is flat, which can fully contact the iron plate 18 to ensure magnetic stability. Material selection: High-temperature neodymium iron boron magnet (EH series); Core advantages: High temperature resistance meets standards: EH series neodymium iron boron magnets can operate at a maximum temperature of 200℃, and can withstand the heat conducted to the limiting groove 15 after the mold is heated, avoiding magnetic attenuation or loss due to high temperature.
