[0002] Molds are the various molds and tools used in industrial production to produce desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. Simply put, a mold is a tool used to create a molded object. This tool is composed of various parts, and different molds are composed of different parts. It primarily achieves surface processing by changing the physical state of the molded material, and is often called the "mother of industry." Injection molds are tools used to produce plastic products. Generally, they consist of an upper mold and a lower mold. During injection molding, the upper and lower molds close together to form the runner system and the mold cavity for the plastic product. During injection molding, the mold is clamped to the injection molding machine. Molten plastic is injected into the mold cavity and cooled and formed within the mold cavity. Simultaneously, the molten plastic cools in the runner system, forming a solid. After the plastic product is formed, the upper and lower molds separate, and the plastic product is ejected from the mold cavity by the ejection system. Finally, the upper and lower molds close again for the next injection. The entire injection molding process is a cyclical process.

[0003] With the rapid development of electronic technology, the market demand for electronic watches continues to grow. As a portable smart device, electronic watches are widely used in daily life. In order to better protect electronic watches, electronic watch cases have emerged.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1-7 In an embodiment of the present invention, an optical colorful mold for an electronic watch protective cover includes an upper mold 1 and a lower mold 2. The upper mold 1 has an upper mold core 3, and the lower mold 2 has a lower mold core 4. The upper mold 1 and the lower mold 2 are butted together so that the upper mold core 3 and the lower mold core 4 are butted together to form a mold cavity 5 for molding a product.

[0033] A texture forming groove 6 is provided along the parting surface of the upper mold core 3 , and a texture structure 7 with optical properties is engraved on the groove wall of the texture forming groove 6 .

[0034] In the technical solution of the present invention, a texture forming groove 6 is provided on the parting surface of the upper mold core 3. Firstly, the parting surface is a position in the mold that is relatively easy to process and operate, which facilitates the production of the texture forming groove 6. Secondly, the texture forming groove 6 is provided at this position so that during the molding process of the electronic watch protective cover, plastic and other materials can be smoothly filled into the texture forming groove 6 to replicate the texture structure 7. In addition, the position of the parting surface can also be adjusted according to the design requirements of the electronic watch protective cover to achieve different texture effects.

[0035] In order to engrave a texture structure 7 with optical properties on the groove wall of the texture forming groove 6, advanced processing technologies such as laser lithography and nanoimprinting can be used. These technologies can achieve high-precision texture production and ensure the accuracy of the texture shape and size. Laser lithography technology uses the high energy and high focus of the laser beam to etch a tiny texture structure 7 on the material surface. Nanoimprinting technology achieves high-precision texture replication by imprinting nanometer-scale texture patterns on the mold surface.

[0036] The texture structure 7 with optical properties is designed based on optical principles. These textures can reflect, refract, diffract and other optical effects on incident light, thereby producing a dazzling visual effect. For example, by designing a texture of a specific shape, light can be interfered and diffracted at different angles to produce light of different colors. Textures of different depths and spacings can adjust the reflection and refraction angles of light, thereby achieving different dazzling effects. In addition, the optical effect of the texture can be enhanced by selecting materials with specific optical properties. Furthermore, parameters such as the shape, size and depth of the texture forming groove 6 are important factors affecting the optical dazzling effect. The shape of the texture forming groove 6 can be various forms such as straight lines, curves, waves, etc. Different shapes can produce different optical effects. The selection of size and depth needs to take into account the fluidity of the material and the requirements of the molding process to ensure the clarity and stability of the texture structure 7.

[0037] In summary, by arranging a texture forming groove 6 in the mold cavity 5 of the mold, and engraving a texture structure 7 with optical properties on the groove wall of the texture forming groove 6, the formed electronic watch protective cover product has a unique optically dazzling appearance and visual effect, which can stand out from many products and attract the attention of consumers. Whether in color, gloss or texture, it can give people a brand new feeling and meet consumers' demand for personalization. In today's fierce market competition, unique product design is an important means for enterprises to enhance their competitiveness. The optically dazzling electronic watch protective cover has a unique appearance effect and design concept, which can attract the attention of consumers and improve the competitiveness of products. This unique design can also enable enterprises to stand out in the market, distinguish themselves from other brands, and establish their own brand image.

[0038] In the embodiment of the present invention, the texture structure 7 is formed in the texture forming groove 6 by laser photolithography technology to form a texture with a microstructure.

[0039] Laser lithography is a high-precision micro-nanofabrication technology that utilizes the high energy and focus of a laser beam to precisely etch a microstructured texture within the texture forming groove 6. This technology enables precise control of the texture shape, size, and depth, thereby ensuring the stability and consistency of the optical color effect.

[0040] In mold design, applying laser lithography technology to the production of textured forming grooves 6 can give full play to its advantages of high precision, high efficiency and high flexibility. By adjusting laser parameters such as laser power, scanning speed, and focus depth, various complex texture structures 7 can be etched on different materials to meet different design requirements.

[0041] Among them, the microstructure texture formed by laser lithography technology in the texture forming groove 6 is the key to achieving the optical dazzling effect. These microstructures can be in the form of nano-scale or micron-scale protrusions, depressions, grooves, etc., which can reflect, refract, diffract and other optical effects on the incident light, thereby producing a dazzling visual effect; and the design of the microstructure texture needs to take into account the optical principles and material properties. For example, by reasonably designing the shape, size and spacing of the microstructure, the reflection and refraction angles of light can be adjusted to achieve specific color and gloss effects. At the same time, it is also necessary to select materials with suitable optical properties to enhance the optical effect of the texture.

[0042] In an embodiment of the present invention, the texture of the microstructure is composed of a series of convex units and concave units alternating to form a grating-like structure.

[0043] The microstructure of this mold is composed of a series of alternating raised and recessed units. This design is based on the application of optical principles such as interference and diffraction of light. When light hits this surface with a specific microstructure, the raised and recessed units will produce different reflection, refraction and diffraction effects on the light.

[0044] By precisely controlling the parameters of laser lithography technology, a microstructure consisting of alternating raised and recessed units can be etched within the texture forming groove 6, thereby forming a grating-like structure. The grating-like structure can selectively reflect, refract, and diffract incident light, causing light of different wavelengths to interfere with each other at specific angles, producing an optically dazzling effect.

[0045] In the embodiment of the present invention, an interlocking groove 8 is opened along the surface of the upper mold core 3, and a product-profiling insert 9 is detachably connected to the interlocking groove 8, and the texture forming groove 6 is formed on the parting surface of the product-profiling insert 9.

[0046] The upper mold core 3 is provided with a fitting groove 8 for the precise installation and positioning of a product-profile insert 9. The size and shape of the fitting groove 8 match the product-profile insert 9, ensuring that the product-profile insert 9 is tightly coupled to the upper mold core 3 after installation and prevents loosening or displacement during use of the mold. Furthermore, the product-profile insert 9 is designed based on the specific shape and size of the electronic watch, and can accurately replicate the shape of the electronic watch case in the mold. By forming a textured forming groove 6 on the parting surface of the product-profile insert 9, a textured structure 7 with optical properties can be directly applied to specific areas of the electronic watch case.

[0047] The product-profile insert 9 and the fitting groove 8 are detachably connected. This design facilitates quick replacement during the production process according to different electronic watch models or customer needs. For example, the insert can be detachably installed using bolts, snaps, or magnetic connections. The detachable connection also makes mold maintenance more convenient. When the product-profile insert 9 is worn or damaged, it can be replaced alone without replacing the entire upper mold core 3, thereby reducing mold maintenance costs.

[0048] At the same time, through the detachable product-profile insert 9, the mold can be suitable for the production of different models of electronic watch protective cases. By simply replacing the corresponding product-profile insert 9, the shape and size of the mold can be quickly adjusted to meet the needs of different products and achieve the effects of different texture structures 7. This versatility and flexibility greatly improves the efficiency and economy of mold use. For enterprises, it can reduce the inventory quantity of molds and reduce production costs, while also being able to respond to market changes and customer needs more quickly.

[0049] In the embodiment of the present invention, at least one side of the product-profile insert 9 is extended with an abutment portion 10, and the fitting groove 8 is extended toward its outer side with a step groove 11 that matches the abutment portion 10;

[0050] After the product-profile insert 9 is placed in the fitting groove 8 , the inner surface of the upper mold 1 abuts against the outer surface of the product-profile insert 9 , so that the product-profile insert 9 is limited to the fitting groove 8 .

[0051] An abutment portion 10 is extended from at least one side of the product-profile insert 9, and a step groove 11 is extended outwardly to cooperate with the abutment portion 10. This design is to provide an additional positioning and fixing mechanism when installing the product-profile insert 9. When the product-profile insert 9 is placed in the fitting groove 8, the abutment portion 10 will cooperate with the step groove 11 to form a mechanical locking structure. This cooperation method can ensure that the product-profile insert 9 will not move or rotate laterally during the use of the mold, thereby ensuring the accuracy and stability of the molding of the electronic watch protective cover. At the same time, the design of the step groove 11 can also limit the insertion depth of the product-profile insert 9, ensuring that the installation position of the product-profile insert 9 is accurate;

[0052] When the product-shaped insert 9 is placed in the fitting groove 8, the inner surface of the upper mold 1 abuts against the outer surface of the product-shaped insert 9. This design further enhances the stability of the product-shaped insert 9 in the mold. The inner surface of the upper mold 1 applies pressure to the product-shaped insert 9, so that the product-shaped insert 9 fits tightly in the fitting groove 8, preventing the product-shaped insert 9 from loosening or displacement during the molding process. This abutment method can also ensure the sealing between the product-shaped insert 9 and the upper mold 1, avoiding problems such as plastic leakage during the molding process. At the same time, the close contact between the inner surface of the upper mold 1 and the outer surface of the product-shaped insert 9 also helps to transmit the molding pressure, ensuring the molding quality of the electronic watch protective cover.

[0053] In the embodiment of the present invention, the texture forming groove 6 is generally annular, and the parting surface of the product profiling insert 9 is located inside the texture forming groove 6 to form a product forming area 12, and outside the texture forming groove 6 to form a sealing abutment area 13.

[0054] The texture forming groove 6 is designed to be generally annular in order to form a continuous annular area with an optically dazzling effect on the electronic watch protective cover. This design can increase the aesthetics and uniqueness of the electronic watch protective cover, and can also improve the structural strength of the electronic watch protective cover to a certain extent.

[0055] On the parting surface of the product contour insert 9, the area within the texture molding groove 6 is defined as the product molding area 12. This area is the main molding part of the electronic watch protective cover. Its shape and size match the appearance of the electronic watch to ensure that the electronic watch protective cover can tightly wrap the watch.

[0056] The area outside the texture molding groove 6 forms a sealing abutment area 13. When the mold is closed, this area is in close contact with other parts of the upper mold 1 and the lower mold 2, playing a role of sealing and fixing. The design of the sealing abutment area 13 can ensure that the plastic material will not leak during the molding process, and can also ensure that the edge of the electronic watch protective cover is flat and smooth, thereby improving the quality of the product.

[0057] In the embodiment of the present invention, the lower mold 2 is provided with an ejection mechanism, which includes an ejector plate 14 movably connected to the lower mold 2 and a first ejector 15 and a second ejector 16 connected to the ejector plate 14;

[0058] The first ejector pins 15 are located at the center of the product forming area 12 , and the second ejector pins 16 are located around the product forming area 12 and arranged around the first ejector pins 15 .

[0059] The first ejector pin 15 at the center and the second ejector pins 16 arranged on the circumference can provide uniform and stable ejection force, preventing the product from being subjected to uneven external force during the demolding process, which may cause deformation, damage or stress concentration. This helps to ensure the dimensional accuracy and appearance quality of the product and reduce the defective rate. In particular, for electronic watch protective cases with optical colorful effects, the precise demolding process can ensure that the texture structure 7 is not damaged, maintaining the optical performance and aesthetics of the product.

[0060] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
