[0026] Combination Figure 1 The automotive decorative part provided in the embodiment of the present application includes a skeleton layer 1 and a transparent layer 2, wherein the skeleton layer 1 has a preset color; the transparent layer 2 covers the skeleton layer 1, and the transparent layer 2 is in a transparent state; wherein the transparent layer 2 is injection molded on the skeleton layer 1. In this embodiment, the automotive decorative part has a double-layer structure, wherein the transparent layer 2 is molded on the skeleton layer 1 by injection molding, the skeleton layer 1 can serve as a supporting base and provide color gloss, the transparent layer 2 can provide protection for the skeleton layer 1, and at the same time, the color gloss of the skeleton layer 1 can be presented through the transparent layer 2. In some embodiments, the skeleton layer 1 and the transparent layer 2 have the same cross-sectional shape, so that the transparent layer 2 can completely cover the skeleton layer 1.

[0027] The automotive decorative parts provided in the embodiments of the present application are provided with color by a skeleton layer 1 obtained by injection molding, and a transparent layer 2 is injection-molded on the skeleton layer 1 to protect the skeleton layer 1 so that the color and gloss of the skeleton layer 1 can be presented through the transparent layer 2. While ensuring the color and gloss of the parts, the colored parts of the parts can be effectively prevented from being scratched. The entire production process does not require a painting process, which reduces the appearance quality problems that are easily caused by the painting process, improves the product qualification rate, reduces the parts cost (the product material cost is saved by more than 25% under actual application conditions), and avoids environmental pollution caused by painting.

[0028] For example, in combination Figure 2a~Figure 2f The automotive decorative part provided in the embodiment of the present application can be made by the following method: obtaining a first resin in a molten state, which has a preset color after solidification; injecting the first resin into a first mold cavity A, solidifying and molding to obtain a skeleton layer 1 of the decorative part, the cross-sectional shape of the first mold cavity A is the same as the cross-sectional shape of the decorative part; placing the skeleton layer 1 into a second mold cavity B, and making the skeleton layer 1 and the bottom of the second mold cavity B spaced apart by a preset distance to form a closed cavity, the cross-sectional shape of the second mold cavity B is the same as the cross-sectional shape of the decorative part; obtaining a second resin in a molten state, which is transparent after solidification; injecting the second resin into the closed cavity, solidifying and molding on the surface of the skeleton layer 1 to obtain a transparent layer 2 of the decorative part, the thickness of the transparent layer 2 is the same as the preset distance; demolding the skeleton layer 1 covered with the transparent layer 2 to obtain the decorative part. The second mold cavity B can have the same cross-sectional shape as the first mold cavity A, and the depth of the second mold cavity B can be slightly greater than the depth of the first mold cavity A, so that when the skeleton layer 1 is placed in the second mold cavity B, the skeleton layer 1 can be spaced apart from the bottom of the second mold cavity B. The specific size of the second mold cavity B and the first mold cavity A can be determined according to the size of the decorative part. In some embodiments, the surface roughness Ra of the first mold cavity A and the second mold cavity B is less than 0.032 μm. In this embodiment, by controlling the surface roughness of the first mold cavity A and the second mold cavity B, the surfaces of the first mold cavity A and the second mold cavity B can have a higher level of polishing, which can make the gloss of the decorative part better.

[0029] More specifically, in some embodiments, the decorative part is manufactured in an injection molding machine, which includes a first mold cavity A and a second mold cavity B. The first mold cavity A and the second mold cavity B are arranged at different circumferential positions of the same circle, for example, they can be arranged at two end positions of the same diameter of the circle. The depth of the second mold cavity B is greater than the depth of the first mold cavity A. The injection molding machine also includes a first injection tube C and a second injection tube D. The first injection tube C is connected to the first mold cavity A to inject material into the first mold cavity A through the first injection tube C, and the second injection tube D is connected to the second mold cavity B to inject material into the second mold cavity B through the second injection tube D. The injection molding machine also includes a movable mold that can translate and rotate, and the movable mold can be molded with the first mold cavity A and the second mold cavity B. The method for manufacturing the decorative part includes: controlling the movable mold to mold with the first mold cavity A (see Figure 2a ), and then inject the first resin into the first mold cavity A, and after pressure maintenance and cooling, the first resin is solidified to form the skeleton layer 1 (see Figure 2b ); Control the movable mold to translate in a direction away from the first mold cavity A, so that the movable mold brings the skeleton layer 1 out of the first mold cavity A; Control the movable mold to rotate so that the movable mold drives the skeleton layer 1 to align with the second mold cavity B (refer to Figure 2c ), for example, the movable mold can be controlled to rotate 180°; the movable mold can be controlled to translate toward the direction close to the second mold cavity B, so that the movable mold puts the skeleton layer 1 into the second mold cavity B, wherein when the movable mold is molded with the second mold cavity B, the skeleton layer 1 on the movable mold is spaced a preset distance from the bottom of the second mold cavity B to form a closed cavity (see Figure 2d ); injecting the second resin into the closed cavity (refer to Figure 2e ), after pressure maintenance and cooling, the second resin is solidified on the surface of the skeleton layer 1 to form a transparent layer 2 (see Figure 2f ). During continuous production, the above steps are repeated in sequence.

[0030] In some embodiments, the material of the skeleton layer 1 is a polycarbonate / acrylonitrile-butadiene-styrene terpolymer mixture or polycarbonate. Preferably, the material of the skeleton layer 1 is a high-gloss polycarbonate / acrylonitrile-butadiene-styrene terpolymer mixture (PC / ABS), for example, it can be CB2430HG material of Pulite, of course, it can also be high-gloss polycarbonate. In some embodiments, the preset color of the skeleton layer 1 is high-gloss black, high-gloss white or high-gloss color, so as to respectively produce high-gloss black decorative parts, high-gloss white decorative parts, and high-gloss color decorative parts. For example, the high-gloss color can include high-gloss red, high-gloss blue, high-gloss green, high-gloss brown and other colors.

[0031] In some embodiments, the material of the transparent layer 2 is thermoplastic polyurethane. Thermoplastic polyurethane (TPU) material is transparent after curing, and can meet the performance requirements of automotive applications such as weather resistance, light resistance, chemical resistance, scratch resistance, emission performance, and odor. For example, the thermoplastic polyurethane can be Covestro's Desmopan ® Thermoplastic polyurethane, BASF's Elastollan ® Thermoplastic polyurethane. Of course, in other embodiments, the material of the transparent layer 2 can also be two-component thermosetting polyurethane. Two-component thermosetting polyurethane also has the characteristics of transparency and high wear resistance.

[0032] In some embodiments, the thickness of the skeleton layer 1 is 2 mm to 3.5 mm, and the thickness of the transparent layer 2 is 0.3 mm to 3 mm. The thickness of the skeleton layer 1 and the transparent layer 2 can meet the requirements of the structure, strength and shape of the decorative parts. Preferably, in some embodiments, the thickness of the transparent layer 2 is 1 mm to 3 mm. This arrangement increases the thickness of the transparent layer 2, can produce a depth of field effect, and enhance the three-dimensional decorative effect.

[0033] In some embodiments, a surface of one side of the skeleton layer provided with the transparent layer is provided with a three-dimensional decorative texture. In this embodiment, this arrangement can make the finished decorative parts present different patterns, thereby facilitating the acquisition of more beautiful and diverse decorative parts. Exemplarily, the three-dimensional decorative texture can be obtained by laser engraving.
