Description

Technical Field

[0001] This utility model relates to the field of fish bait technology, specifically a carbon fiber fish bait. Background Technology

[0002] As we all know, existing fish baits are generally made of metal or plastic, which have low structural strength and are heavy. Since fish baits need to create splashes on the water surface to attract target fish from a distance, solid metal materials cannot achieve this function. Only hollow metal or plastic materials can be made, which reduces the overall strength of the fish bait. It is very easy to be deformed by external impacts, affecting its service life. Moreover, once deformed, its movement in the water is unstable, and the probability of catching fish is extremely low, which affects the use by anglers.

[0003] For example, the popper is one of the most commonly used lures. It is a transliteration of the English word "popper," which literally means "to make a popping sound." It has a large head that is usually concave or slightly tilted. When dragged on the water's surface, it makes a sound that attracts larger fish to attack. It can be used to lure freshwater fish such as mandarin fish, snakehead, and freshwater bass, as well as marine fish such as silver carp, seven-star bass, and barracuda. ​​They are usually made of metal or plastic and are very easy to deform. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a carbon fiber fish bait that is simple in structure, lightweight, has high structural strength, is non-toxic and environmentally friendly, has good mechanical properties, and has a long service life.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A carbon fiber fish bait, characterized in that the fish bait includes a connecting ring, a foam inner core, and a carbon fiber outer cover. The foam inner core is shaped like a fish body, and the outer cover is integrally molded and wrapped around the foam inner core. The foam inner core is made of PMI or PET foam board. The connecting ring includes a front connecting ring, a belly connecting ring, and a tail connecting ring. The front connecting ring, belly connecting ring, and tail connecting ring are respectively fixed to the front, belly, and tail of the foam inner core and extend out of the carbon fiber outer cover.

[0030] Furthermore, one end of the steel wire extends forward and bends to form a front connecting ring 5, then extends downward and backward and bends downward at the abdominal position to form an abdominal connecting ring 6, then bends upward and extends backward and bends upward at the tail end to form a tail connecting ring 7, then bends forward and is fixed.

[0031] The molding method of the wave-crawling fish bait of this utility model is as follows: First, a mold is made, which is divided into an upper mold plate 8, a lower mold plate 9, a front upper mold head 10, and a front lower mold head 11. The lower end face of the upper mold plate 8 is provided with an upper mold groove 12, the upper end face of the lower mold plate 9 is provided with a lower mold groove 13, the rear end of the front upper mold head 10 is provided with an upper forming protrusion 14, and the rear end of the front lower mold head 11 is provided with a lower forming protrusion 15. After the upper mold plate 8, lower mold plate 9, front upper mold head 10, and front lower mold head are closed, the upper mold groove is... 12. A bait forming cavity is formed between the lower mold groove 13, the upper forming protrusion 14, and the lower forming protrusion 15. The upper mold groove 12 of the upper template 8 and the lower mold groove 13 of the lower template 9 have symmetrically provided belly placement grooves 16 and tail placement grooves 17 at their respective positions. The lower end face of the upper forming protrusion 14 and the upper end face of the lower forming protrusion 15 are symmetrically provided with front-end placement grooves 18 for accommodating the front-end connecting ring. The lower template 9 is equipped with... Vertical guide pillars 19 are installed, and vertical guide holes 20 that mate with the vertical guide pillars 19 are provided on the upper template 8. Horizontal guide pillars 21 are installed on the front and rear sides of the upper and lower front mold heads respectively. Horizontal guide holes 22 that mate with the horizontal guide pillars 21 are provided on the front front and lower mold heads between the horizontal guide pillars 21 of the upper and lower front mold heads respectively. Inclined slopes 23 are provided on the inclined slopes 23. A middle guide hole 24 is provided on the inclined slopes 23. Guide rods 25 are connected to the upper template 8 and lower template 9 corresponding to the middle guide hole 24 respectively. The guide rods 25 are inserted into the middle guide hole 24 to realize the mold closing guidance function. In the manufacturing process, PMI foam board is first taken. It can be polymethyl methacrylate foam board or PET foam board. The main component of PET foam board is polyethylene terephthalate, commonly known as polyester resin.PET foam is a type of closed-cell thermoplastic foam with certain shear and compressive strength, so it is often used as the core material of sandwich structures and is widely used in construction, road transportation, rail transportation, aviation, media, wind power and other fields. Using engraving and cutting technology and CNC machining technology for foam boards, symmetrical left foam board 2 and right foam board 3 are cut out. The left foam board 2 and right foam board 3 have integrally formed steel wire connecting rings and counterweight mounting grooves. The front connecting ring 5, belly connecting ring 6 and tail connecting ring 7 of the bait are all made by bending steel wire. The foam core is formed in one piece, with the counterweight fitted onto the steel wire. The one-piece steel wire structure and counterweight are then placed in the mounting grooves of the left foam board 2 and right foam board 3, and the left and right foam boards 2 and 3 are joined together. After joining, carbon fiber prepreg tape is wrapped around the outside of the left and right foam boards 2 and 3 to complete the foam core. Then, carbon fiber prepreg fabric is laid on the lower mold cavity of the lower mold 9. After laying, the foam core is placed on the carbon fiber prepreg fabric of the lower mold 9, and then the top and front end of the foam core are wrapped with carbon fiber prepreg fabric, completely enclosing the foam core. After wrapping with carbon fiber prepreg, the upper mold plate 8 is closed downwards, and the front upper mold head 10 and front lower mold head 11 are moved backwards and inserted into the front end of the upper mold plate 8 and lower mold plate 9. The mixture is then heated and molded at high temperature inside the bait forming cavity. After molding, the product is demolded by first demolding the front upper mold head 10 and front lower mold head 11 forwards, then demolding the upper mold plate 8 upwards, thus completing the demolding process and achieving one-piece carbon fiber molding of the bait. The diameter of the steel wire is 1mm, therefore, the diameter of the front upper mold head and front lower mold head is 0.5mm, which is crucial for demolding. During the process, there will be no difficulty in demolding due to the steel wires. Because the foam core is made of PMI foam board material, it will not soften or deform during the high-temperature molding of carbon fiber, ensuring the internal strength of the molded bait. Moreover, it is non-toxic and environmentally friendly, and also solves the problem of carbon fiber molding of bait. The final bait has good mechanical properties and can withstand 150-200 kg of pressure. Due to the above structure, this utility model has the advantages of simple structure, light weight, high structural strength, non-toxic and environmentally friendly, good mechanical properties, and long service life.
