Abstract
Description
Technical Field
[0001] This invention relates to a jigging fish bait, and more particularly to a soft TPR-coated jigging fish bait and its manufacturing process. Background Technology
[0002] In the artificial lure industry, there is a type of artificial lure that uses the texture of soft rubber materials, combined with certain color and texture designs, to lure fish to bite. A common method is to coat a metal lure with TPR (Thermo-Plastic-Rubber material). The disadvantage of this method is that it cannot better adhere to the internal metal plate while maintaining the softness of TPR. Although TPR material has good flexibility and plasticity, it cannot meet certain requirements in terms of adhesion and tensile strength. In addition, poor process control during the coating process can lead to insufficient adhesion between TPR material and metal lure. Furthermore, the performance of TPR material under different conditions can also affect the final molded product, failing to meet expectations. Furthermore, the tensile strength of this type of bait does not meet expectations. The existing structural design has problems with the matching degree between the internal iron plate and the pull ring. It is usually cast directly outside the steel wire of the pull ring, resulting in a small contact area. When the iron plate is subjected to tensile force, cracks are easily formed at the fracture point of the contact area. The small contact area causes excessive stress concentration, which eventually leads to tensile fracture of the iron plate. Therefore, it is necessary to optimize the process flow and structural design, and redesign the bait structure to make it more compatible with TPR material, so as to improve the fit and tensile strength. Summary of the Invention
[0003] To address the shortcomings of the aforementioned technologies, this invention provides a soft TPR-wrapped iron plate fish bait and its production process.
[0004] To solve the above technical problems, the technical solution adopted by the present invention is: a soft TPR-wrapped iron plate fish bait, including a flat hexagonal iron plate, an irregular steel wire passing through the length of the iron plate, the irregular steel wire being bent at both ends of the iron plate to form pull rings, the iron plate and the pull rings being covered with a clamping layer, and also including a soft TPR wrapping that is perfectly matched and wrapped around the iron plate with the clamping layer.
[0005] The irregular steel wire that runs through the iron plate is divided into a connecting part and a disconnecting part. The connecting part is continuously connected between two pull rings, and the disconnecting part is intermittently connected between the two pull rings. The disconnecting node in the middle of the disconnecting part is bent at 90° near the center of the iron plate.
[0006] The thickness of the soft TPR outer sheath ranges from 0.2 mm to 0.5 mm.
[0007] Furthermore, the soft TPR outer casing includes a set of parallel long sides and two sets of parallel short sides of equal length. The bevel between the long side on one side and the two short sides on the adjacent side forms a cutting edge. The long side on that side serves as the cutting edge of the two intersecting cutting edges. The bevel between the two adjacent short sides forms a spiked surface. The intersection of the two spiked surfaces is located inside the loop of the pull ring at the location.
[0008] Furthermore, the long side is set along the length of the iron plate, and the inclination angles of the blades corresponding to the two long sides are not the same.
[0009] Furthermore, the angle of inclination of the spikes formed between all adjacent short sides is consistent.
[0010] Furthermore, the iron plate has a circular plane in the middle. There are two circular planes, which are located on two opposite sides of the iron plate and are arranged symmetrically to each other.
[0011] Furthermore, a circular groove is provided on the soft TPR outer casing at the position corresponding to the circular plane, and the bottom surface of the circular groove fits into the circular plane.
[0012] Furthermore, the thickness of the soft TPR outer layer ranges from 0.3 mm.
[0013] A production process for soft TPR-coated iron plate fish bait, comprising the production process of the iron plate and the production process of the soft TPR coating, including the following steps:
[0014] The production process of iron plates involves placing irregularly shaped steel wires into a die-casting mold, using a die-casting machine to inject lead to form the iron plate, and then performing precision machining on the formed iron plate.
[0015] The production process of soft TPR is to put the finely machined iron plate into the TPR mold, push the TPR material at a temperature of 230°C for injection molding, allow it to cool naturally after injection, demold after 6.5 minutes of cooling, and allow it to cool naturally again.
[0016] Further, the finished iron plate undergoes finishing processes, including polishing and grinding the excess parts of the die-cast iron plate surface; after polishing and grinding, a primer is sprayed on, and then it is placed in an oven at 160℃ for 90 minutes; then it is finely ground, hot stamping oil is applied, and it is placed in an oven at 120℃ for 90 minutes; then, without baking, hot stamping and 3D printing colors are applied, or colored paint is sprayed on and then it is placed in an oven at 80℃ for 30 minutes; finally, fisheye lenses are attached, a protective clear varnish is sprayed on, and it is placed in an oven at 100℃ for 90 minutes to complete the finishing process of the iron plate.
[0017] Furthermore, in the production process of the outer soft TPR, different colors of ordinary glitter and luminous glitter are placed in the TPR material for decoration while maintaining a 230° angle.
[0018] This invention discloses a soft TPR-coated iron plate fish bait and its production process. The design and production process of the soft TPR-coated iron plate fish bait bring the following advantages:
[0019] Protecting the internal structure: The soft TPR outer layer is flexible and stretchy, providing better protection for the internal steel plate and shaped wire. During fishing, fish bites can easily damage the bait. The soft TPR outer layer acts as a cushion and protector, effectively extending the bait's lifespan.
[0020] Enhanced strength and tensile strength: The irregularly shaped steel wires interwoven into the jig, through their design of penetrating the jig and bending into a pull ring, improve the hook's tensile strength. Simultaneously, the outer layered structure further reinforces the connection between the jig and the pull ring, increasing the bait's stability and durability.
[0021] Increased ease of use: The soft TPR outer coating material is replaceable, meaning that if the outer layer of the bait is damaged or severely worn during use, the coating material can be replaced with a new one without replacing the entire jig structure. This saves costs and facilitates maintenance and continued use of jig baits.
[0022] Offering multiple lure effects: The flat hexagonal shape of the jig, the design of its bladed and spiked surfaces, and the choice of colors and finishes for the TPR coating create a variety of lure effects. This design allows the jig lure to more realistically mimic the shape and swimming motion of fish in the water, increasing the likelihood of attracting fish to bite.
[0023] Improved catch efficiency: The structure and characteristics of soft TPR-wrapped jig baits make them more attractive to fish. The water flow impact effect, stability, and visual appeal make the bait more enticing, increasing the efficiency and success rate of catching fish. Attached Figure Description

Detailed Implementation
[0030] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0031] like Figure 1 and 2 The soft TPR-coated iron plate fish bait shown includes a flat hexagonal iron plate 100, a shaped steel wire 300 running through the length of the iron plate, the shaped steel wire being bent at both ends of the iron plate to form pull rings, and the iron plate and pull rings being covered with a clamping layer, and also includes, for example, Figure 3 and 4 The shape shown perfectly matches the soft TPR outer casing 200 covering the iron plate with the clamp layer; the flexibility of the outer TPR material can better and more fully protect the inner iron plate. The TPR material has better ductility, which better protects the inner iron plate when the fish attacks. At the same time, the outer TPR material is easy to replace, and the iron plate can be reused repeatedly.
[0032] To structurally enhance the tensile strength of this soft TPR-wrapped jig lure, the shape of the inner steel wire has been optimized to ensure maximum tensile strength, and a clamping layer has been added to the jig and pull ring to improve reliability. The irregularly shaped steel wire runs along the length of the jig, such as... Figure 3 The irregular steel wire shown is bent at both ends of the iron plate to form pull rings 303. The irregular steel wire passing through the iron plate is divided into a connecting part 301 and a disconnecting part 302. The connecting part is continuously connected between the two pull rings, and the disconnecting part is intermittently connected between the two pull rings. The disconnecting node in the middle of the disconnecting part is bent at 90° near the center inside the iron plate. The tensile strength of the irregular steel wire is tested to reach more than 150 LBS.
[0033] The thickness range of soft TPR outer packaging is 0.2 mm to 0.5 mm, and the thickness range of soft TPR outer packaging is 0.3 mm.
[0034] The soft TPR outer casing includes a set of parallel long sides and two sets of parallel short sides of equal length. The bevel between any one long side and the two adjacent short sides forms a cutting edge 10, which serves as the edge 11 of the two intersecting cutting edges. The bevel between two adjacent short sides forms a spiked surface 20, and the intersection 21 of the two spiked surfaces is located within the loop of the pull ring at that position. The long sides are positioned along the length of the sheet metal, and the inclination angles of the cutting edges corresponding to the two long sides are inconsistent. The inclination angles of the spiked surfaces formed between all adjacent short sides are consistent.
[0035] The long sides are set along the length of the metal plate, and their angles of inclination vary. However, the angle of inclination of the spiked surfaces formed between all adjacent short sides is consistent. The shape of the soft TPR-wrapped metal plate bait has the following advantages when encountering water currents underwater:
[0036] The water flow collision effect, created by the flat hexagonal shape of the soft TPR wrapper and the design of its bladed and spiked surfaces, generates a water flow collision effect under the influence of water. When water flows over the bladed surface, it creates intense eddies and changes in water flow, resulting in a water flow collision effect. This effect attracts fish and stimulates their appetite. The long side is set along the length of the jig, and the varying angles of inclination provide different options, extend bait retention time, and increase visual appeal. Fish have different food preferences and perception abilities. Therefore, different angles of inclination on the bladed surface offer a variety of choices to meet the tastes and perception conditions of different fish. Some fish may prefer steeper blades, while others may prefer gentler blades. Because the angles of inclination of the bladed surfaces corresponding to the long side are inconsistent, the force of the water flow will also vary on different bladed surfaces. This results in different speeds of change and pressure variations on different bladed surfaces. This difference extends the bait retention time, provides a longer trapping window, and increases the chances of catching fish. Meanwhile, the different angles of the blade create varying reflections and refractions under light, increasing the visual appeal of the bait. Fish are sensitive to reflections and refractions, so this design can more effectively attract their attention.
[0037] To increase stability, the soft TPR-wrapped jig bait is made of a soft material that maintains good stability in the water. The shape of the jig and the design of the spiked surface reduce the force of water flow on the bait, making it float or sink more stably in the water. As a result, fish can more easily detect the presence of the bait and are more likely to bite.
[0038] To increase its allure, the blade and spiked surfaces of the jig are designed with multiple protrusions and angles. These protrusions and angles create significant water flow variations and pressure differences. These variations and differences attract the attention of fish and stimulate their hunting instincts. Therefore, soft TPR-coated jigs increase their allure and improve the probability of catching fish.
[0039] The iron plate has a circular plane 101 in the middle. There are two circular planes, which are located on two opposite sides of the iron plate and are symmetrically arranged. A circular groove 201 is provided on the soft TPR outer cover at the position corresponding to the circular plane. The bottom surface of the circular groove is in contact with the circular plane, and the circular groove is used to attach a circular label.
[0040] A production process for soft TPR-coated iron plate fish bait, comprising the production process of the iron plate and the production process of the soft TPR coating, including the following steps:
[0041] The production process of iron plates involves placing irregularly shaped steel wires into a die-casting mold, using a die-casting machine to inject lead to form the iron plate into shape, creating a lead layer, and then performing precision machining on the formed iron plate.
[0042] The production process of soft TPR is to put the finely machined iron plate into the TPR mold, push the TPR material at a temperature of 230°C for injection molding, allow it to cool naturally after injection, demold after 6.5 minutes of cooling, and allow it to cool naturally again.
[0043] Further, the finished iron plate undergoes finishing processes, including polishing and grinding the excess parts of the die-cast iron plate surface; after polishing and grinding, a primer is sprayed on, and then it is placed in an oven at 160℃ for 90 minutes; then it is finely ground, hot stamping oil is applied, and it is placed in an oven at 120℃ for 90 minutes; then, without baking, hot stamping and 3D printing colors are applied, or colored paint is sprayed on and then it is placed in an oven at 80℃ for 30 minutes; finally, fisheye lenses are attached, a protective clear varnish is sprayed on, and it is placed in an oven at 100℃ for 90 minutes to complete the finishing process of the iron plate.
[0044] In the production process of soft TPR, different colors of ordinary glitter and luminous glitter are placed in the TPR material for decoration while maintaining a 230° angle.
[0045] The above embodiments are not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present invention are also within the protection scope of the present invention.
