[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0024] This embodiment is a molding process of a melamine product, which consists of the following steps:

[0025] Step a, molding and manufacturing a first color embryo 1, wherein the surface of the first color embryo 1 has concave-convex patterns;

[0026] Step b, molding the second color embryo 2 on the first color embryo 1, the second color embryo 2 is molded on the surface of the first color embryo 1 with concave and convex patterns, and the second color embryo 2 has decorative patterns formed by alternating light and dark colors due to different thicknesses of raw materials.

[0027] The second color raw material used to manufacture the second color embryo 2 is a translucent melamine material. The color of the second color raw material is different from the color of the first color raw material used to manufacture the first color embryo 1. The decorative graphics are patterns, patterns or texts. The texts are divided into Chinese characters, numbers, letters, symbols, etc.

[0028] The above-mentioned molding process can be molded in a pair of molds, that is, the pressing of the first color embryo 1 and the pressing of the second color embryo 2 use the same lower mold in the same mold, the first color embryo 1 has a surface with a concave and convex pattern and is pressed by the first upper mold, and the second color embryo 2 is pressed by the second upper mold. The first upper mold and the second upper mold can be rotated with each other. The molding surface of the first upper mold has a concave and convex pattern for forming a decorative pattern on the first color embryo 1, and the molding surface of the second upper mold is inconsistent with the molding surface of the first upper mold. Specifically, the molding surface of the second upper mold is a smooth surface or a concave and convex surface. If the concave and convex surface of the second upper mold is similar in shape to the concave and convex surface of the first upper mold, and the depth is inconsistent.

[0029] The above-mentioned molding process can also be carried out in two sets of molds. In step a, the first color embryo 1 is pressed in the first mold, and the first mold has a concave-convex pattern for forming decorative graphics; in step b, the first color embryo 1 is taken out of the first mold and then placed in the second mold, and one of the molding surfaces of the second mold is consistent with one of the molding surfaces of the first mold, and the other molding surface of the second mold is inconsistent with the other molding surface of the first mold. Specifically, when the other molding surface of the second mold is a smooth plane or curved surface, it is inconsistent with the other molding surface of the first mold; when the other molding surface of the second mold is a smooth concave-convex surface, the concave-convex surface of the second mold and the concave-convex surface of the first mold are the same or similar in shape, but the depth is inconsistent. The above-mentioned molding process can not only be used in combination with the two molds as described above, but can also be expanded to a product in which multiple molds are used in combination.

[0030] Further, in this embodiment, the surface of the first color embryo 1 for combining with the second color embryo 2 has concave-convex patterns, and the outer surface of the second color embryo 2 is smooth, and the outer surface refers to the side of the second color embryo exposed to the outside. By hot-pressing two raw materials of different colors twice and combining them into a melamine product, the body of the product formed in this way can form decorative patterns and texts in the first color embryo 1 and / or the second color embryo 2 due to the different thickness of the raw materials. The decorative patterns and texts can be decorative or practical elements such as patterns, textures, words, numbers, letters, etc. In this embodiment, since the first color embryo 1 and the second color embryo 2 of the melamine product are both concave-convex structures of different depths, the decorative patterns and texts displayed on the melamine product of this embodiment can be located on the surface of the first color embryo 1 exposed to the outside, can also be located on the surface of the second color embryo 2 exposed to the outside, and can also be located on the surfaces of the first color embryo 1 and the second color embryo 2 exposed to the outside at the same time. The decorative patterns and texts formed on the first color embryo 1 and / or the second color embryo 2 are based on the texture of the concave-convex patterns and texts of the first color embryo 1.

[0031] Since the decorative graphics in this embodiment are formed inside the first color embryo body 1 and / or the second color embryo body 2, they are not easily damaged during cleaning and use.

[0032] The outer surfaces of the first color embryo 1 and the second color embryo 2 in this embodiment that are exposed to the outside are both smooth surfaces, which can be smooth planes or curved surfaces, or smooth wavy concave and convex surfaces. The surface is smooth without obvious concave and convex, which is easier to clean during use and has a longer service life.

[0033] The melamine products in this embodiment can be products made of melamine materials such as tableware, tea sets, and handicrafts. The tableware can be basins, bowls, plates, spoons, etc., the tea sets can be teapots, teacups, etc., and the handicrafts can be ornaments, picture frames, etc.

[0034] Specifically, this embodiment is further described by taking a basin as an example.

[0035] like Figure 1 As shown, it includes a basin body, which includes a first color embryo body 1 and a second color embryo body 2. The first color embryo body 1 is formed by a first color raw material through a first molding, and the second color embryo body 2 is formed by a second color raw material through a second molding on the surface of the first color embryo body 1.

[0036] In this embodiment, the inner surface of the basin can form different shades of colors due to the inconsistent thickness of the second color embryo 2, and the different shades of colors outline the decorative patterns; the outer surface of the basin can form different shades of colors due to the inconsistent thickness of the first color embryo 1, and the different shades of colors outline the decorative patterns. The decorative patterns of the first color embryo 1 and the second color embryo 2 are formed by the different thicknesses of their own, and are both based on the concave and convex patterns of the combination of the first color embryo 1 and the second color embryo 1.

[0037] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
