Description

Technical Field

[0001] This invention relates to the field of nail product processing technology, and more specifically to a process for molding false nail tips to create a dynamic heart-shaped cat-eye nail effect. Background Technology

[0002] Patent application number 202321771848.5 discloses a magnetic attraction and fixation device for a cat-eye effect on wearable nail plates. The device includes an upper cover, an upper magnetic mold, a lower magnetic mold, and a pre-curing lamp. The lower magnetic mold is positioned below and corresponding to the upper magnetic mold, forming a receiving cavity between them. The upper magnetic mold is mounted on the upper cover, and the pre-curing lamp is detachably connected to the upper cover. By mounting the upper magnetic mold on the upper cover, the upper and lower magnetic molds can be easily engaged and disengaged, making operation convenient. The upper and lower magnetic molds work together on the nail plate on the nail plate mounting plate to achieve the cat-eye effect. The pre-curing lamp allows for curing the magnetic coating after molding, achieving a fixed magnetic effect.

[0003] Existing cat-eye nail art techniques mostly present static textures, lacking dynamic changes and having a weak visual impact. Furthermore, traditional molding processes can only create cat-eye effects on a single nail piece at a time, making it impossible to process the same batch of nail pieces in bulk. This results in low production efficiency, poor process flexibility, and difficulty in meeting diverse nail art needs. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned defects of the prior art and provide a process for molding false nail tips with a dynamic heart-shaped cat-eye nail effect. This process can flexibly achieve dynamic cat-eye effects on any single, multiple, or all false nail tips on the same nail tip blank in batches. Furthermore, it incorporates measures to interweave the production of other static cat-eye effects, enabling the sequential completion of multiple cat-eye effects within the same process. The process combines standardization and flexibility, taking into account both mass production efficiency and personalized customization, meeting the aesthetic and practical needs of different scenarios, and making exquisite and dynamic nail effects easier to achieve and longer-lasting.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a process for molding false nail tips with a dynamic heart-shaped cat-eye nail art effect, characterized by comprising the following steps: (1) Prepare magnetic suction module and curing lamp assembly. The magnetic suction module includes magnetic upper mold and magnetic lower mold, and the curing lamp assembly includes UV lamp strip; (2) Magnetic field preparation: According to different customer needs, the heart-shaped cat-eye effect of any single or multiple or all fake nail pieces on the same nail blank can be flexibly achieved in batches. The magnetic field is arranged next to the nail holder that supports the fake nail piece that needs to achieve the heart-shaped cat-eye effect. (3) Place a strong magnetic column in the storage slot next to the plate holder where a magnetic field needs to be arranged, and then place a magnetic rod near the corresponding light-transmitting hole. The magnetic rod is fixed in the corresponding groove between the needle groove and the light-transmitting hole by pressing the copper plate with a plastic wheel. The V-shaped magnetic suction head at the front end of the magnetic rod is presented in the corresponding light-transmitting hole. The magnetic foot at the rear end of the magnetic rod extends through to the outside of the corresponding needle groove. When the upper magnetic suction mold and the lower magnetic suction mold are closed, the magnetic foot contacts the corresponding strong magnetic column, thereby conducting and finally magnetizing the magnetic suction head together. (4) In the storage slot, light-transmitting hole and needle-passing slot next to the plate holder where no magnetic field is required, the above-mentioned strong magnetic column and magnetic rod are not installed, and the light-blocking cover is directly placed in the corresponding light-transmitting hole. (5) Add the cat's eye powder containing magnetic powder to the plastic paint and stir it thoroughly with a mixer at low speed to ensure that the cat's eye powder is evenly dispersed; (6) Take a plate blank and place it in the spray booth. Use the spray gun to sweep and spray it back and forth evenly 1-2 times. Keep the distance between the spray gun and the plate blank 15-25cm during the sweeping and spraying. (7) Magnetic field positioning: Before the coating dries, place the painted nail blank into the nail blank holder of the magnetic lower mold. Each fake nail corresponds to one nail holder. Ensure that each fake nail that needs to achieve the heart-shaped cat-eye effect is placed on the nail holder that has been arranged with the magnetic field. Then, the magnetic upper mold and the magnetic lower mold are closed. The magnetic mold head that is conducted and magnetized approaches the coating surface of the corresponding fake nail. The cat-eye powder in the latter coating is arranged along the direction of the magnetic field. Since the surface of the fake nail is arc-shaped, a hazy large V is formed at the near end of the magnetic field and a hazy small V is formed at the far end of the magnetic field. When the large V and small V meet, a heart-shaped cat-eye effect is formed. (8) Photocuring: The curing lamp is placed on the magnetic module. The ultraviolet light emitted by the UV lamp strip acts on the coating with the completed heart-shaped cat-eye effect through the light-transmitting hole, and then performs a photocuring reaction; while the coating that does not need the heart-shaped cat-eye effect is blocked by the light-shielding cover and is not photocured. (9) Finally, remove the curing lamp assembly, open the magnetic upper mold and magnetic lower mold to take out the semi-finished false nail piece with heart-shaped cat-eye nail art effect, transfer it for medium and low temperature baking and curing, and obtain the finished false nail piece with heart-shaped cat-eye nail art effect.

[0006] This invention can flexibly and in batches create dynamic heart-shaped cat-eye effects on any single, multiple, or all artificial nail pieces on the same nail blank. It also incorporates measures to create other static cat-eye effects, enabling the sequential completion of multiple cat-eye effects within the same process. The process combines standardization and flexibility, taking into account both mass production efficiency and personalized customization, meeting the aesthetic and practical needs of different scenarios, and making exquisite and dynamic nail art effects easier to achieve and longer-lasting.

[0007] The dynamic heart-shaped cat-eye effect of this invention is achieved through precise magnetic powder arrangement and magnetic field control. The heart pattern presents a dynamic sense of light and shadow flow as the viewing angle changes, gradually enlarging and shrinking, with a strong dynamic visual impact. It can easily create a rich and three-dimensional aesthetic, far exceeding the static decorative effect of ordinary nail art.

[0008] The principle behind the dynamic visual effect of the heart-shaped cat-eye effect in this invention is as follows: When the nail coating is treated with a V-shaped magnetic grinding head, a heart-shaped cat-eye effect appears. This is mainly related to the shape of the magnetic grinding head and the way the magnetic field works. The magnetic part of the V-shaped grinding head forms two magnetic field regions at an angle. When these two magnetic fields act on the cat-eye gel containing magnetic powder, the magnetic powder aligns along the direction of the magnetic field. Then, the angle of the V-shape forms a convergence point of the magnetic field, causing the magnetic powder to follow a symmetrical arc at the center and sides of the angle. Finally, they overlap to form a heart-like outline—the magnetic field on both sides guides the magnetic powder to form two arcs of the heart, while the apex of the angle corresponds to the tip of the heart, thus presenting a heart-shaped cat-eye effect.

[0009] The dynamic heart-shaped cat-eye effect appears to "shrink" or "expand" when the fake nail moves. The core reason is that changes in the viewing angle alter the visual field of the magnetic powder arrangement guided by the magnetic field, changing the angle between your line of sight and the reflective band of the magnetic powder. When the angle is directly facing you, you can see the entire heart outline formed by the magnetic powder arrangement, making it appear "larger." When the angle is tilted (upward or downward after facing directly), the visible range of the reflective band is compressed, and the edges become blurred due to reduced reflection, making the heart outline appear "shrink" or even disappear in parts. Simply put, it's like looking at a flashlight beam: the beam is largest when facing directly, and smaller and narrower when tilted. Essentially, the visible range of light (in this case, the magnetic powder reflection) changes with the angle.

[0010] This invention employs a combination of "light curing" and "baking curing" processes to achieve the curing of two cat-eye effects in a step-by-step manner. It also facilitates the secondary curing of the previous heart-shaped cat-eye effect, ensuring that the coating adheres tightly to the nail plate. This process not only preserves the stability of the cat-eye magnetic effect but also improves the overall wear resistance and weather resistance, extending the service life.

[0011] Explanation of terms: Armor plate blank. The size of the armor plates on the same plate is not consistent. Instead, at least one set of armor plates, matching the size of ten fingers of a human hand, are injected together from the injection molding machine. Generally, two sets are per plate, arranged in an array on both sides.

[0012] Preferably, the magnetic module has the following structure: it includes a pair of magnetic upper molds and magnetic lower molds forming a split composite structure and made of non-magnetic material. A receiving cavity is provided at the transverse center of the magnetic lower mold. A plate blank holder, matching the shape of the plate blank emerging from the injection molding machine, is inserted into the receiving cavity. The plate blank holder has two rows of equally spaced plate blank holders. A receiving groove is provided on the side of each plate blank holder. Each receiving groove is perpendicular to the receiving cavity but they are not interconnected. A free-state strong... The magnetic column has two rows of equally spaced light-transmitting holes arranged at the transverse center of the magnetic suction upper mold. Each light-transmitting hole corresponds to one of the axle holders. Each light-transmitting hole has a needle groove that is not connected to it on its side. A magnetic rod is installed on the isolation strip between each pair of needle grooves and light-transmitting holes through a detachable mechanism. One end of each magnetic rod has a magnetic suction head that extends horizontally into the corresponding light-transmitting hole. The magnetic suction head is V-shaped. The other end of each magnetic rod has a magnetic foot that extends vertically through the corresponding needle groove. The detachable mechanism includes a groove disposed on the isolation strip, the two ends of the groove being connected to the needle groove and the light-transmitting hole respectively, a screw hole being disposed on the side of the groove, a copper sheet being covered on the groove, a plastic wheel being pressed onto the copper sheet, and the plastic wheel being fixed by a bolt that fits in the screw hole. The magnetic module also includes a number of light-shielding covers equal to the number of light-transmitting holes. Each light-shielding cover has a step at its lower end that is interference-fitted with the corresponding light-transmitting hole.

[0013] This invention aims to flexibly and in batches create dynamic heart-shaped cat-eye effects on any single, multiple, or all artificial nail pieces on the same nail plate blank. It also incorporates measures for creating other static cat-eye effects, achieving the seamless completion of multiple cat-eye effects within the same process. This is achieved in three layers: First, the magnetic field arrangement of the magnetic modules next to the nail plate holders is independent, without interference, and can be easily disassembled and installed as needed. Second, during the light-curing process of the heart-shaped cat-eye effect nail plate coating, other nail plate coatings that do not require a cat-eye effect must not be light-cured. Therefore, each light-transmitting hole exists independently, and a light-shielding cover is added to selectively block UV rays. Finally, before baking and curing, other cat-eye effects are incorporated and interspersed.

[0014] The strong magnetic column generates a magnetic field that magnetizes the surrounding magnetic materials. Even without contact with the magnetic guide foot, as long as it is close, it can be magnetized and magnetically attracted. In this invention, the magnetic guide foot is preferably connected to one of the two end faces of the strong magnetic column. The contact part is the radius length. The copper sheet, plastic wheel and isolation strip all serve to isolate the magnetic field.

[0015] This invention adds a light-shielding cover to the light-transmitting hole to prevent all the painted armor pieces on the same armor plate from being light-cured, leaving some to lay the technical groundwork for subsequent measures to incorporate other cat-eye effects.

[0016] Preferably, the magnetic upper mold and the magnetic lower mold are connected by a pair of spaced-apart hinges.

[0017] The magnetic suction module of this invention connects the upper and lower molds via hinges, which not only ensures precise alignment when the upper and lower molds are fitted together, but also allows for flexible opening and closing, making it convenient to pick up and put in nail pieces and adjust the magnetic suction angle, thereby improving the efficiency and stability of cat-eye effect production.

[0018] Preferably, a handle is provided on the outer end face of the magnetic upper mold.

[0019] This invention adds a handle to the magnetic upper film, which can easily control the opening and closing of the upper film, avoiding the impact of hand contact with the mold on the magnetic attraction accuracy, and improving the convenience of operation and the stability of the effect.

[0020] Preferably, the curing lamp assembly includes a gantry-shaped lampshade, and several UV light strips are pasted on the inner bottom surface of the lampshade, the number of which is the same as the number of rows of light-transmitting holes, with each UV light strip corresponding to one row of light-transmitting holes.

[0021] The UV light strips inside the gantry-type lampshade of this invention are arranged in an array corresponding to the light-transmitting holes. This ensures that each light-transmitting area receives uniform and sufficient ultraviolet light, and also accurately focuses on the curing position, thereby improving the efficiency and consistency of UV varnish curing.

[0022] Preferably, the magnetic powder content in the cat's eye powder is in the range of 12%-15%, and the proportion of cat's eye powder in the plastic paint is preferably in the range of 0.3%-30%.

[0023] The invention can be adjusted according to the cat-eye effect, coating texture and curing status. If a significant cat-eye effect is desired, the proportion of cat-eye powder can be higher, and it is recommended to be 10%-30%. If it is desired that the varnish maintains good fluidity and transparency, and considering the curing effect and adhesion, it should be controlled at 0.3%-10%.

[0024] Preferably, the plastic paint is a UV varnish.

[0025] The UV varnish of this invention is a transparent coating that is rapidly cured and dried by ultraviolet (UV) irradiation. It is mainly composed of oligomers (such as acrylic resin), reactive diluents, photoinitiators, and a small amount of additives (such as leveling agents and defoamers). It is often used for spraying and varnishing wearable nail tips to improve the brightness and adhesion of the nail tips.

[0026] Preferably, the nozzle diameter of the spray gun is between 1.5 and 2.0 mm.

[0027] The nozzle diameter of the spray gun in this invention is selected to avoid clogging by cat's eye powder.

[0028] Preferably, in steps (7), (8) and (9) above, the magnetic attraction time of the heart-shaped cat-eye effect coating is preferably controlled within 3-10 seconds, the photocuring reaction time is preferably controlled within 30-60 seconds, and the baking temperature for medium-low temperature baking curing is controlled within 60-80 degrees Celsius.

[0029] In this invention, the heart-shaped cat-eye nail art uses a magnetic suction time of 3-10 seconds to precisely shape the cat-eye texture, followed by step-by-step curing with light for 30-60 seconds and baking at a medium-low temperature of 60-80℃. This ensures a stable and long-lasting effect while avoiding over-processing that could damage the nail material, thus improving production efficiency and the quality of the finished product.

[0030] As a preferred option, in step (9) above, other cat-eye effects can also be created by mixing the uncured false nail tip coating with magnetic molds of different shapes. The magnetic particles in the cat-eye powder will be attracted and gathered under the action of the magnetic field, arranged in an orderly manner into a specific shape, and then baked and cured together with the semi-finished heart-shaped cat-eye nail art effect false nail tip at medium and low temperature to obtain the finished product.

[0031] In order to flexibly and in batches realize dynamic heart-shaped cat-eye effects on any single, multiple, or all artificial nail pieces on the same nail blank, this invention incorporates measures to interweave the production of other static cat-eye effects, so as to achieve the sequential completion of multiple cat-eye effects within the same process.

[0032] Beneficial effects: (1) This invention can flexibly achieve dynamic cat-eye effects for any single or multiple or all false nail pieces on the same nail blank plate in batches. It can also incorporate measures to create other static cat-eye effects, so as to achieve the sequential completion of multiple cat-eye effects in the same process. The process is both standardized and flexible, taking into account mass production efficiency and personalized customization, meeting the aesthetic and practical needs of different scenarios, making exquisite and dynamic nail art effects easier to achieve and longer-lasting.

[0033] (2) The dynamic heart-shaped cat-eye effect of the present invention is achieved through precise magnetic powder arrangement and magnetic field control. The heart pattern presents a dynamic light and shadow flow as the viewing angle changes, gradually enlarging and shrinking, with strong dynamic visual impact. It can easily create a rich three-dimensional aesthetic, far exceeding the static decorative effect of ordinary nail art. Attached Figure Description

[0036] To make the technical means, creative features and objectives of the present invention easier to understand, the present invention will be further described below in conjunction with specific embodiments.

[0037] Example: Figure 1 As shown, a magnetic shaping device for cat-eye false nail tips includes a magnetic module 1 and a curing lamp assembly.

[0038] like Figure 2 and Figure 3 As shown, the magnetic module 1 includes a pair of magnetic upper mold 4 and magnetic lower mold 5, which form a split composite structure and are made of non-magnetic material (aluminum). The magnetic upper mold 4 and magnetic lower mold 5 are connected by a pair of spaced-apart hinges 6. A handle 7 is provided on the outer end face of the magnetic upper mold 4.

[0039] like Figure 4 , Figure 5 and Figure 6 As shown, a storage cavity 8 penetrating the thickness of the lower mold is provided in the transverse center of the magnetic lower mold 5. A plate blank holder 9 that matches the shape of the plate blank coming out of the injection molding machine is inserted into the storage cavity 8. The plate blank holder 9 has two rows of plate blank holders 10 arranged at equal intervals (ten in each row, for a total of twenty). Each plate blank holder 10 has a storage groove 11 on its side. Each storage groove 11 is arranged perpendicular to the storage cavity 10, but they are not interconnected. A free-state strong magnetic column 12 is placed in each storage groove 11. The strong magnetic column 12 can also be fixed in the corresponding storage groove 11 by glue or other auxiliary materials.

[0040] The upper magnetic mold 4 has two rows of equally spaced light-transmitting holes 13 (ten in each row, for a total of twenty) arranged at its horizontal center. Each light-transmitting hole 13 corresponds to a plate holder 10 when the upper magnetic mold 4 and the lower magnetic mold 5 are closed. Each light-transmitting hole 13 has a needle groove 14 that is not connected to it. A magnetic rod 16 is installed on the isolation strip 15 between each pair of needle grooves 14 and light-transmitting holes 13 through a detachable mechanism. One end of each magnetic rod 16 has a magnetic mold head 17 that extends horizontally into the corresponding light-transmitting hole. The magnetic mold head 17 is V-shaped. The other end of each magnetic rod 17 has a magnetic foot 18 that extends vertically through the corresponding needle groove 14 and into the corresponding storage groove 11 when the upper magnetic mold 4 and the lower magnetic mold 5 are closed.

[0041] The detachable mechanism includes a groove 19 set on the isolation strip. The two ends of the groove 19 are respectively connected to the needle groove 14 and the light-transmitting hole 13. A screw hole 20 is provided on the side of the groove 19. A top pressure plate 21 made of non-magnetic material is covered on the groove 19. The top pressure plate 21 is a copper sheet. A top pressure wheel 22 made of non-magnetic material is pressed on the top pressure plate 21. The top pressure wheel 22 is a plastic wheel. The top pressure wheel 22 is fixed by a bolt 23 that fits in the screw hole 20.

[0042] The curing lamp assembly includes a gantry-shaped lamp cover 2. Two UV light strips 3, the same number as the number of rows of light-transmitting holes, are pasted on the inner bottom surface of the lamp cover 2. Each UV light strip 3 corresponds to a row of light-transmitting holes 13 when the magnetic upper mold 4 and magnetic lower mold 5 are closed.

[0043] The magnetic module 1 also includes twenty light-shielding covers 24, the same number as the light-transmitting holes. The light-shielding covers 24 are also made of non-magnetic materials, preferably thick plastic (such as PVC or ABS). Each light-shielding cover 24 has a step at its lower end that is interference-fitted with the corresponding light-transmitting hole 13.

[0044] A process for creating false nail tips with a dynamic heart-shaped cat-eye effect includes the following steps: (1) Prepare magnetic suction module and curing lamp assembly. The magnetic suction module includes magnetic upper mold and magnetic lower mold, and the curing lamp assembly includes UV lamp strip; (2) Magnetic field preparation: According to different customer needs, the heart-shaped cat-eye effect of any single or multiple or all fake nail pieces on the same nail blank can be flexibly achieved in batches. The magnetic field is arranged next to the nail holder that supports the fake nail piece that needs to achieve the heart-shaped cat-eye effect. (3) Place a strong magnetic column in the storage slot next to the plate holder where a magnetic field needs to be arranged, and then place a magnetic rod near the corresponding light-transmitting hole. The magnetic rod is fixed in the corresponding groove between the needle groove and the light-transmitting hole by pressing the copper plate with a plastic wheel. The V-shaped magnetic suction head at the front end of the magnetic rod is presented in the corresponding light-transmitting hole. The magnetic foot at the rear end of the magnetic rod extends through to the outside of the corresponding needle groove. When the upper magnetic suction mold and the lower magnetic suction mold are closed, the magnetic foot contacts the corresponding strong magnetic column, thereby conducting and finally magnetizing the magnetic suction head together. (4) In the storage slot, light-transmitting hole and needle-passing slot next to the plate holder where no magnetic field is required, the above-mentioned strong magnetic column and magnetic rod are not installed, and the light-blocking cover is directly placed in the corresponding light-transmitting hole. (5) Add the cat's eye powder containing magnetic powder to the plastic paint and stir it thoroughly with a mixer at low speed to ensure that the cat's eye powder is evenly dispersed; (6) Take a plate blank and place it in the spray booth. Use the spray gun to sweep and spray it back and forth evenly 1-2 times. Keep the distance between the spray gun and the plate blank 15-25cm during the sweeping and spraying. (7) Magnetic field positioning: Before the coating dries, place the painted nail blank into the nail blank holder of the magnetic lower mold. Each fake nail corresponds to one nail holder. Ensure that each fake nail that needs to achieve the heart-shaped cat-eye effect is placed on the nail holder that has been arranged with the magnetic field. Then, the magnetic upper mold and the magnetic lower mold are closed. The magnetic mold head that is conducted and magnetized approaches the coating surface of the corresponding fake nail. The cat-eye powder in the latter coating is arranged along the direction of the magnetic field. Since the surface of the fake nail is arc-shaped, a hazy large V is formed at the near end of the magnetic field and a hazy small V is formed at the far end of the magnetic field. When the large V and small V meet, a heart-shaped cat-eye effect is formed. (8) Photocuring: The curing lamp is placed on the magnetic module. The ultraviolet light emitted by the UV lamp strip acts on the coating with the completed heart-shaped cat-eye effect through the light-transmitting hole, and then performs a photocuring reaction; while the coating that does not need the heart-shaped cat-eye effect is blocked by the light-shielding cover and is not photocured. (9) Finally, remove the curing lamp assembly, open the magnetic upper mold and magnetic lower mold to take out the semi-finished false nail piece with heart-shaped cat-eye nail art effect, transfer it for medium and low temperature baking and curing, and obtain the finished false nail piece with heart-shaped cat-eye nail art effect.

[0045] In step (5) above, the magnetic powder content in the cat's eye powder is preferably in the range of 12%-15%, and the proportion of cat's eye powder in the plastic paint is preferably in the range of 0.3%-30%, and the plastic paint is a UV varnish.

[0046] If you want a more pronounced cat-eye effect, the proportion of cat-eye powder can be higher, ideally between 10% and 30%. If you want the varnish to maintain good fluidity and transparency, and also consider curing effect and adhesion, then keep it between 0.3% and 10%.

[0047] In step (6) above, the nozzle diameter of the spray gun is preferably 1.5-2.0 mm.

[0048] In step (7) above, the magnetic attraction time of the heart-shaped cat-eye effect coating is preferably controlled within 3-10 seconds.

[0049] In step (8) above, the time of photocuring reaction is preferably controlled within 30-60 seconds.

[0050] In step (9) above, the baking temperature for medium-low temperature baking and curing is controlled at 60-80 degrees Celsius.

[0051] In step (9) above, other cat-eye effects can be created by mixing the uncured false nail coating. Magnetic suction heads of different shapes are used to magnetically attract the cat-eye powder. The magnetic particles in the cat-eye powder will be attracted and gathered under the action of the magnetic field, arranged in an orderly manner into a specific shape, and then baked together with the semi-finished heart-shaped cat-eye nail art effect false nail to medium and low temperature to obtain the finished product.
