The aluminum sheet surface 12 and the silicone surface 14 are used for forming the corresponding positions on the hot stamping plate, so the corresponding names are used. For example, the aluminum sheet surface 12 is used to contact with the aluminum sheet in the hot stamping plate and press into an aluminum sheet layer, and the silicone surface 14 is used to contact with the silicone in the hot stamping plate and press into a silicone layer. A concave pattern 15 is provided on the silicone surface 14. Correspondingly, when the hot stamping plate 20 is made, a protrusion 23 is formed on the hot stamping plate 20. When the protrusion 23 on the hot stamping plate 20 is used to hot stamp the exterior decoration product, a concave area can be formed on the exterior decoration product, so that the product can produce a three-dimensional hot stamping visual effect, which improves the visibility and grade of the product.

[0037] The shape of the concave lines 15 can be designed according to actual needs. Optionally, the shape of the concave lines 15 includes at least one of a dot-shaped concave, a straight line, an arc line, and a folded line. In one possible embodiment, when the concave lines 15 are dot-shaped, a plurality of spaced concave points are arranged on the silicone surface 14. When the hot stamping plate is made using the hot stamping plate mold, the surface of the hot stamping plate forms mutually spaced convex points. In another possible embodiment, a plurality of spaced strip-shaped grooves are arranged on the silicone surface 14, and the shape of the grooves includes a straight line, an arc line, or a folded line. The silicone surface 14 may be provided with a concave line 15 of one shape, or may be provided with two or more different shapes of concave lines 15.

[0038] The concave lines 15 are formed by thermal processing of at least one of cutting with a tool, burning with a laser, and etching with a chemical solution. During processing, the concave lines 15 can be formed by cutting directly on the silicone surface 14 with a tool, or by burning the silicone surface 14 with a laser, or by etching the silicone surface 14 with a chemical agent.

[0039] The depth of the concave lines 15 can be determined according to actual needs. Optionally, the depth of the concave lines is 0.01mm to 1mm. Optionally, the depth of the concave lines is 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9 or 1mm.

[0041] The silicone surface 14 is provided with a ridge, and the height of the ridge is less than or equal to the height of the step surface 13. That is, the ridge is an extension of the step surface 13, and both have the same function when making a hot stamping plate. The hot stamping plate, the step surface 13, and the ridge corresponding to the area all form a dent. When hot stamping, the product corresponding to the dent cannot be hot stamped, achieving a diversified effect of the product after hot stamping. The shape of the ridge is not limited. Optionally, the shape of the upper surface of the ridge includes a straight strip structure, a curved strip structure, a polygonal structure or other irregular structures. The ridge can also divide the silicone surface 14 into two or more areas.

[0042] A hot stamping plate is made from a hot stamping plate mold. Figure 3 and Figure 4 As shown, the hot stamping plate 20 includes a silicone layer 21 and an aluminum layer 22 fixedly combined, the silicone layer 21 includes an outer surface and an inner surface arranged opposite to each other, the inner surface is bonded to the aluminum layer 22, and a protrusion 23 is provided on the outer surface. During production, the silicone layer 21 and the aluminum layer 22 are placed in a hot stamping plate mold, the outer surface of the silicone layer 21 is bonded to the silicone surface 14 of the mold body 10, the aluminum sheet layer 22 is bonded to the inner surface of the silicone layer 21, and the aluminum sheet layer 22 is bonded to the aluminum sheet surface 12. A large-scale extrusion molding machine is used to apply pressure to the aluminum layer, and the silicone layer 21 and the aluminum layer 22 are pressed together by heating to form the hot stamping plate 20. Since there are concave lines on the silicone surface 14, protrusions 23 are formed on the outer surface of the silicone layer 21 accordingly. The hot stamping plate is formed with dents in the areas corresponding to the step surface 13 and the ridges. Optionally, as Figure 3 As shown, the thickness D1 of the silicone layer 21 is 5±0.5 mm, and the thickness D2 of the aluminum layer 22 is 1±0.2 mm.

[0043] A three-dimensional hot stamping process comprises the following steps:

[0044] Electrostatic dust removal: Electrostatic dust removal is performed on the hot stamping surface of the product 30; Figure 7 and Figure 8 The schematic diagram of the product 30 before hot stamping is shown. The electrostatic dust removal step can keep the hot stamping surface of the product, i.e., the exterior part, clean, and reduce the phenomenon of hot stamping leakage or dust on the surface of the gold foil after hot stamping, which affects the appearance of the product.

[0045] Placing the product: placing the product 30 in the hot stamping jig, and exposing the hot stamping surface of the product 30; that is, the non-hot stamping surface of the product is located in the jig, and the hot stamping surface of the product faces the outside of the hot stamping jig;

[0046] Placing the hot stamping foil: placing the hot stamping foil 33 on the hot stamping surface of the product 30;

[0047] Hot stamping: Start the hot stamping machine, install the hot stamping plate 20 on the hot stamping machine, and drive the hot stamping plate 20 to press the hot stamping foil 33 at high temperature, so as to press the hot stamping foil 33 on the hot stamping surface of the product 30, and use the protrusions 23 on the hot stamping plate 20 to embed the hot stamping foil 33 into the hot stamping surface of the product 30. That is, a concave area 34 is formed on the hot stamping surface of the product. Figure 5 and Figure 6 Schematic diagram of product 30 after hot stamping. The hot stamping machine includes a common hot stamping machine or a curved arm hot stamping machine. The hot stamping machine drives the hot stamping plate 20 to press down, and the silicone layer 21 of the hot stamping plate 20 presses the hot stamping foil paper onto the hot stamping surface of the product, that is, the hot stamping is completed by pressing in the present application. This hot stamping process can achieve a three-dimensional metal decorative surface effect through one hot stamping, which reduces the production cost of the product and shortens the production cycle of the product compared with the traditional hot stamping and printing process.

[0048] In the hot stamping step, the air pressure of the hot stamping machine is 3kg to 10kg. Optionally, the air pressure of the hot stamping machine is 3kg, 4kg, 5kg, 6kg, 7kg, 8kg, 9kg or 10kg. Optionally, the air pressure of the hot stamping machine is 3kg to 6kg. Optionally, the air pressure of the hot stamping machine is 6kg to 10kg. The temperature of the electric heating cover in the hot stamping machine is 300℃ to 360℃. Optionally, the temperature of the electric heating cover is 300℃, 310℃, 320℃, 330℃, 340℃, 350℃ or 360℃. The temperature of the hot stamping plate is 220℃ to 280℃. Optionally, the temperature of the hot stamping plate is 220℃, 230℃, 240℃, 250℃, 260℃, 270℃ or 280℃. During lamination, the hot stamping surface is in a molten state to bond the hot stamping foil to the hot stamping surface. When the silicone layer 21 of the hot stamping plate contacts the stamping surface, the stamping surface made of polymer material is in a molten state at high temperature, so that the protrusion 23 of the stamping plate 20 can be used to embed the stamping foil 33 into the inside of the stamping surface, thereby forming a recessed area on the stamping surface. During the cooling and solidification process of the product, the stamping foil is firmly bonded to the product. Therefore, a recessed area 34 can be formed on the product obtained by this stamping process, so that the product can produce a three-dimensional stamping visual effect, thereby improving the visibility and grade of the product.

[0049] When the hot stamping surface is the back side 32 of the product 30, it also includes a printing or spraying step, and a layer of ink is printed or sprayed on the outer surface of the hot stamping foil 33, and the product 30 is made of a transparent material. Since the hot stamping foil is attached to the back of the product, the hot stamping foil with a three-dimensional hot stamping effect can only be seen through the product, so the product is made of a transparent material. The ink layer can cover the small holes that are not hot stamped during hot stamping, so the color of the ink layer can be selected to be the same or similar to the color of the hot stamping foil; optionally, the hot stamping foil on the back of the product is fixed to the cosmetic container by bonding, and since the ink layer is highly hydrophobic, the bonding strength between the hot stamping foil and the adhesive or glue is improved.

[0050] When the hot stamping surface is the front side 31 of the product 30, a spraying step is also included, in which a transparent protective layer is sprayed on the outer surface of the hot stamping foil 33, and the product 30 is made of a transparent material or an opaque material. Since the hot stamping foil is on the outside of the product, the material of the product can be transparent or opaque, which will not affect the effect of the product forming a three-dimensional metal decorative surface; the back of the product is fixed to the cosmetic container by means of snapping, bonding, fusion bonding, etc. After the product is hot stamped, a transparent protective layer is sprayed on the outer surface of the hot stamping foil, so that the effect of three-dimensional hot stamping can be displayed, and the hot stamping foil can be prevented from being scratched or abraded during use. Optionally, the material of the protective layer includes a polymer transparent protective paint layer.

[0051] Product 30 can be made of colorless transparent plastic, colored transparent plastic or colored opaque plastic, and colored plastic can be made by adding masterbatch to plastic particles. Optionally, product 30 is a sheet structure, and the material of product 30 includes TPU material, PP material, PVC material, PET material, PETG material or PCR material. Among them, TPU (ThermoPlasticpolyUrethane) is thermoplastic polyurethane elastomer rubber, PET (PolyEthylene Terephthalate) is polyethylene terephthalate, PP (PolyPropylene) is polypropylene, PVC (PolyVinyl Chloride) is polyvinyl chloride, PETG (Poly(ethyleneterephthalateco-1,4-cylclohexylenedimethyleneterephthalate)) is polyethylene terephthalate-1,4-cyclohexane dimethanol ester, and PCR (Post-ConsumerRecycled material) is recycled plastic.
