In order to achieve the above object, the utility model discloses a main technical scheme include:

the embodiment of the utility model provides an injection molding in mould of IMR technology double-sided decoration, which comprises a body, the body includes the resin layer, the upper and lower two sides of resin layer are first pattern layer, second pattern layer respectively, be provided with first bond line between resin layer and the first pattern layer, be provided with the second bond line between resin layer and the second pattern layer.

Preferably, the first pattern layer comprises a printed layer of a surface decorative pattern, and the printed layer is printed with a protective layer through a screen.

Preferably, the second pattern layer has the same structure as the first pattern layer.

Preferably, the resin layer is in accordance with the shape of the first pattern layer and the second pattern layer.

Preferably, the first pattern layer and the second pattern layer are integrally laminated and combined on the upper and lower surfaces of the resin layer by injection molding.

(III) advantageous effects

The utility model has the advantages that: the utility model discloses an injection molding in mould of IMR technology double-sided decoration owing to adopt and utilize first pattern layer, second pattern layer to combine in the mode of the upper and lower surface of resin layer through the integrative range upon range of injection moulding, has realized one step of double-sided decoration that targets in place, and not only environmental protection but also economy, the efficient has realized the high-end injection molding surface decoration of multilayer simultaneously.

Detailed Description

For a better understanding of the present invention, reference will now be made in detail to the present invention, examples of which are illustrated in the accompanying drawings. In which the terms "upper", "lower", etc. are used herein to refer to the orientation of the drawings.

The embodiment of the utility model provides a pair of mould internal injection molding that IMR technology two-sided was decorated, including body 10, body 10 includes resin layer 1, and the upper and lower two sides of resin layer 1 are first pattern layer 2, second pattern layer 5 respectively, is provided with first bond line 3 between resin layer 1 and the first pattern layer 2, is provided with second bond line 4 between resin layer 1 and the second pattern layer 5.

In the present embodiment, the first adhesive layer 3 and the second adhesive layer 4 are made of an adhesive having a good adhesiveness such as a resin adhesive.

The first pattern layer 2 comprises a printing layer 21 with a surface decorative pattern, a protective layer 22 is printed on the printing layer 21 through a silk screen, and the protective layer 22 is made of insulating ink commonly used in the market.

The second pattern layer 5 has the same structure as the first pattern layer 2.

Specifically, the resin layer 1 conforms to the shapes of the first pattern layer 2 and the second pattern layer 5.

The first pattern layer 2 and the second pattern layer 5 are integrally laminated and combined on the upper and lower surfaces of the resin layer 1 through injection molding.

In summary, in the present embodiment, the first pattern layer and the second pattern layer are printed layers on which the surface decorative patterns are screen-printed or gravure-printed in advance on the film, then the protective layer is screen-printed on the printed layers to form the decorative film, finally the adhesive layer for bonding with the resin member is printed on the side on which the patterns are printed before being placed in the mold, and then the upper and lower surfaces of the resin layer are simultaneously subjected to in-mold transfer printing while the resin is injected into the injection mold, so as to form the injection molded member with the decorative patterns on the upper and lower surfaces.

In the description of the present invention, it is to be understood that the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
