Problems solved by technology

[0005] The purpose of the present invention is to provide a method for producing an in-mold relief structure with exquisite three-dimensional patterns or characters on the surface of the in-mold product without the need to set a label, so as to solve the existing problems. In the technology, the mold opening cost of the in-mold molding is too high, the surface of the in-mold molding product needs to be provided with a label to form a three-dimensional texture, and the in-mold molding label cannot present exquisite patterns and characters, and it can be applied to the mold of plastic or metal products. Method for making in-mold relief structure of in-mold product

Embodiment （ 2

[0035] As shown in Figures 1 and 3-10, the embodiment (2) of the method for making the best in-mold relief structure includes at least:

[0036] The first step is to set an inner surface 10 and an outer surface 11 on a base layer 1. The aforementioned base layer 1 is a metal plate, and the shape of the aforementioned base layer 1 is set in accordance with the shape of the molding die 4, which can be flat, curved, ring-shaped shape or irregular shape; the inner surface 10 of the aforementioned base layer 1 is engraved with an engraved pattern 100, which can be carved manually or engraved by an engraving machine to carve various exquisite patterns and characters, and the aforementioned engraved pattern The inner surface 10 of the base layer 1 can be partially or completely carved in the form of concave relief, convex relief or concave-convex relief, so that the carving lines presented by the base layer 1 are richer and more varied. The inner surface 10 of the base layer 1 is pro...

Embodiment （ 3

[0040] Such as figure 2 and 3 As shown in -8, the manufacturing method embodiment (3) of the best in-mold relief structure includes at least:

[0041] The first step is to set an inner surface 10 and an outer surface 11 on a base layer 1. The aforementioned base layer 1 is a stretchable film made of a material different from the plastic in-mold product 2, such as a plastic film or a rubber film. The aforementioned base layer The shape of 1 is set according to the shape of the molding die 4, and can be flat, curved, ring-shaped or irregular; the outer surface 11 of the base layer 1 is provided with a three-dimensional decoration 110. The inner surface 10 of the base layer 1 is provided with a release layer 3, and the release layer 3 is made of an oily material different from the plastic in-mold product 2 or a non-stick material different from the plastic in-mold product 2 , such as isolating oil film or easy-to-tear film, etc., to ensure that the plastic in-mold product 2 wi...

Abstract

A preparation method for an embossment structure molded in a mold is disclosed, and the embossment structure is applicable to plastic or metal in-mold molded products such as 3C products, household electrical appliances, mechanical instrument parts or common household products. Concretely, a base layer with the embossment structure or stereo ornamentals is employed, a release layer is arranged on the base layer, and the base layer is firmly arranged in the molding mold by utilizing an adsorption manner of the molding mold, and after in-mold molding is finished, the base layer on the surface of an in-mold molded product is torn off, so that exquisite customized or personally-designed stereo embossment lines are formed on the in-mold molded product at a lowest cost, and beautiful sense, qualitative sense and economic benefit of the in-mold molded product are increased.

Description

technical field [0001] The present invention relates to a method for forming relief structures in a mold; especially a method for forming a relief structure in a plastic or metal mold, using a base layer provided with a relief structure or a three-dimensional decoration, and setting a release layer on the base layer, Use the adsorption method of the forming mold to make the base layer firmly set in the forming mold. After the in-mold molding, the base layer on the surface of the in-mold molding must be torn off to produce exquisite relief lines on the surface of the plastic or metal in-mold molding. Method for forming relief structures. Background technique [0002] Existing in-mold forming products produce three-dimensional decoration technology on the surface of in-mold forming products, such as the invention of Taiwan No. I274651 titled "In-Mold Molding Anti-counterfeiting Method", which is to set concave or convex in the mold groove Then put the in-mold forming label in...
