This kind of fishing rod is usually relatively strong and durable, and is suitable for occasions where greater force is required during fishing or for use in seawater. When die-casting and forming a fiberglass fishing rod, materials such as fiberglass and resin are placed into a mold, and pressure and heat are applied to form the specific shape and structure of the fishing rod. This device is usually used in industrial production to ensure that the fishing rods have consistent quality and performance.

[0003] After retrieval, a Chinese patent discloses a die-casting forming device for fiberglass fishing rods (authorization publication number CN220784639U), which also belongs to the technical field of fiberglass fishing rods, including "a lower mold, both sides of the upper end of the lower mold are fixedly provided with support rods, the upper ends of the support rods are fixedly provided with a support plate, an oil cylinder is fixedly provided on the upper end of the support plate, the lower end of the oil cylinder is fixedly connected with a fastening structure, the fastening structure includes a connecting plate, a buffer column is movably arranged inside the connecting plate, and a spring is sleeved on the outer wall of the buffer column". Although this patented technology can achieve the precise contact between the upper mold and the lower mold.

[0004] However, in the actual application process of this patented technology, the lower mold is always located below the upper mold. When materials such as fiberglass and resin are placed into the mold cavity, the operator's hand may be injured by the mold due to distraction, which poses a certain safety hazard. In view of the above problems, the inventor proposes a die-casting forming device for fiberglass fishing rods to solve the above problems. Content of the Utility Model

Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0020] Embodiment: As Figures 1-4As shown in the figure, the utility model provides a die-casting forming device for fiberglass fishing rods, which includes a bottom plate 1. One side of the bottom plate 1 is fixedly connected with a side plate 2. The top ends of the bottom plate 1 and the side plate 2 are fixedly connected with positioning plates 3 on the mutually remote sides. A threaded rod 4 is rotatably connected between the two positioning plates 3. A moving block 5 is threadedly connected to the outer side of the threaded rod 4. A slide rod 20 is fixedly connected between the two positioning plates 3 near the threaded rod 4. The outer side of the side plate 2 is slidably clamped with the moving block 5. A lower die 6 is arranged between the top ends of the two moving blocks 5. A servo motor 19 is fixedly installed on one side of the positioning plate 3. The driving end of the servo motor 19 is fixedly connected with the threaded rod 4.

[0021] Symmetrically distributed chutes 7 are respectively opened inside the moving blocks 5. Sliders 8 are respectively slidably clamped inside the chutes 7. The top ends of the sliders 8 are fixedly connected with telescopic rods 9. The top ends of the telescopic rods 9 respectively extend out of the top ends of the moving blocks 5 and are fixedly connected with the bottom end of the lower die 6. Springs 10 are respectively arranged between the bottom end of the lower die 6 and the top surface of the moving blocks 5. The springs 10 are movably sleeved on the outer sides of the telescopic rods 9.

[0022] By adopting the above technical solution, when the die is closed, the telescopic rod 9 is pushed to move downward, and the spring 10 is compressed. The spring 10 is used to absorb and relieve the closing impact force, so as to avoid damaging the die or the workpiece due to excessive impact force.

[0023] Guide rods 11 are respectively fixedly connected to the four corners of the top end of the bottom plate 1. A top plate 12 is fixedly connected between the top ends of the guide rods 11.

[0024] By adopting the above technical solution, by arranging the guide rods 11, it is convenient to guide the vertical movement of the die, and at the same time improve the stability during die closing.

[0025] A hydraulic cylinder 13 is fixedly installed in the middle of the top end of the top plate 12. An installation plate 14 is slidably clamped between the outer sides of the guide rods 11. The piston rod of the hydraulic cylinder 13 is fixedly connected with the installation plate 14. A top die 15 is fixedly connected to the bottom end of the installation plate 14.

[0026] By adopting the above technical solution, through the telescopic movement of the piston rod of the hydraulic cylinder 13, the installation plate 14 and the top die 15 are pushed to move vertically along the outer sides of the guide rods 11, so as to control the opening and closing of the die.

[0027] Bearings 16 are respectively fixedly installed at the four corners of the installation plate 14. The bearings 16 are movably sleeved on the outer sides of the guide rods 11.

[0028] By adopting the above technical solution, by arranging the bearings 16, it is convenient for the installation plate 14 to move vertically along the outer sides of the guide rods 11 better.

[0029] A fixed block 17 is fixedly connected to the middle of the top end of the bottom plate 1 and below the lower die 6.

[0030] By adopting the above technical solution, by setting the fixed block 17, when the upper die 15 presses down the lower die 6, the lower die 6 is first pushed to move downward, so that the lower die 6 contacts the sliding groove 7, and the sliding groove 7 is used to support the downward pressure borne by the lower die 6, thereby preventing the pressure from directly acting on the threaded rod 4 and the sliding rod 20 and causing deformation of the rods.

[0031] A control button 18 is fixedly installed on the side of the positioning plate 3 away from the bottom plate 1, and the servo motor 19 is electrically connected to the control button 18.

[0032] By adopting the above technical solution, by setting the control button 18, it is convenient to better control the mold opening and closing operations.

[0033] Working principle: When molding a fiberglass fishing rod by pressing, the servo motor 19 drives the threaded rod 4 to rotate, and at the same time drives the two upper dies 15 to move away from the bottom plate 1 along the outer sides of the threaded rod 4 and the sliding rod 20 respectively, so that the lower die 6 moves from below the upper die 15, and then the materials required for the fiberglass fishing rod are placed inside the mold cavity. Immediately afterwards, the servo motor 19 rotates in the reverse direction to reset the fixed block 17, and then through the elongation of the piston rod of the hydraulic cylinder 13, the mounting plate 14 and the upper die 15 are pushed to move downward along the outer side of the guide rod 11 to close the mold;

[0034] When the mold is closed, the telescopic rod 9 is pushed to move downward and the spring 10 is compressed. The spring 10 is used to absorb and relieve the closing impact force, avoiding damage to the mold or the workpiece due to excessive impact force. At the same time, the lower die 6 contacts the sliding groove 7, and the sliding groove 7 is used to support the downward pressure borne by the lower die 6, thereby preventing the pressure from directly acting on the threaded rod 4 and the sliding rod 20 and causing deformation of the rods.

[0035] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and its equivalent technologies, the present utility model is also intended to include these changes and modifications.
