Description

Multi-layered three-dimensional shell

The invention relates to a surface pattern of a plastic, in particular to a plastic shell panel which can exhibit a layered three-dimensional effect.

In order to gain consumers' popularity and increase market share, today's electronic products need to be constantly updated in addition to better execution performance and more user-friendly operation interface. Through design, they can shape their products. Different characteristics and styles, in turn, increase the consumer's preference for the electronic product. Under this trend, In Mold-Decoration (IMD) has become a surface decoration technology widely used in the industry. It uses in-mold decoration technology to replace the traditional process in painting, printing and heat after forming parts. Stamping...etc., not only can form the surface pattern of the product to increase the visual effect on the appearance, but also reduce the steps and time required for the finished product, and greatly reduce the cost, so it has been widely used in mobile phones and notebooks. Computer and other products.

Conventional products using in-mold decoration technology, although the pattern of the surface of the shell can be diversified, but mostly flat, less visual and three-dimensional visual effects; in addition, a few have a layer of visual effects The shell plate is made by using the in-mold decoration technique on the opposite surfaces (male and female die faces) of a plastic part, and on the male and female molds. The patterns are layered to achieve a shallow stereo effect.

In the above structure, since the male and female molds of the plastic member are all subjected to the in-mold decoration technology, another plastic member needs to be added to protect the in-mold decoration technology provided on the male mold surface of the plastic member. First, the internal structure (such as a hook, positioning post, etc.) originally formed on the male mold surface of the plastic part is now moved to the male mold surface of another plastic part, which not only increases the overall thickness of the product. It also increases the material cost and process time; in addition, the pattern on the male and female molds has only two layers of visual effects after lamination, and the layering and stereoscopic effects formed by them are extremely limited, so it is not cost-effective. In view of the above, the present inventors have made great efforts to study and cooperate with the application of the theory, and finally propose a present invention which is reasonable in design and effective in improving the above-mentioned defects.

An object of the present invention is to provide a shell with a multi-layered three-dimensional effect, so that the pattern of the decorative technology layer exhibits a multi-layered three-dimensional effect.

In order to achieve the above object, the present invention is a multi-layered three-dimensional shell comprising a transparent plastic part, a decorative technical layer and a reflective layer, the transparent plastic part having a first surface and a first surface a second surface, and the second surface is formed with a lens surface, the decorative technique is laminated on the first surface of the transparent plastic part, and the decorative technology layer has a pattern, and the reflective layer is bonded to the second surface of the plastic molding part, wherein the decoration The pattern of the technical layer exhibits a multi-layered three-dimensionality through imaging of the lens surface and the reflective layer of the transparent plastic part.

In order to achieve the above object, the present invention is a multi-layered three-dimensional shell comprising a transparent plastic part, a decorative technical layer, and a reflective layer with a stereoscopic image. The molding member has a first surface and a second surface opposite to the first surface, the decorative technique is laminated on the first surface of the transparent plastic member, the decorative technology layer has a pattern, and the reflective layer with the stereoscopic image is combined with the transparent plastic member The second surface, wherein the pattern of the decorative technology layer exhibits a multi-layered three-dimensionality through the transparent plastic member and in combination with the reflective layer.

Another object of the present invention is to provide a multi-layered three-dimensional shell without increasing the overall thickness, material cost and process time of the product, thereby improving process efficiency.

A further object of the present invention is to provide a shell plate having a multi-layered three-dimensional shape, which can further form a hollow layer in the reflective layer. When a light-emitting module is additionally disposed inside the product of the shell, the light can be Penetrating the hollow layer, transparent plastic parts and decorative technology layers, and increasing the diversity of the pattern of the shell.

Compared with the conventional product, the surface of the product is mostly a plan view or only has a shallow stereo effect. The multi-layered three-dimensional shell of the present invention is formed on the second surface (male mold surface) of the transparent plastic part, and the lens surface is formed. A reflective layer is bonded to the second surface of the transparent plastic part, and the pattern of the decorative technical layer exhibits a multi-layered three-dimensional feeling by the action of the transparent plastic part, the lens surface and the reflective layer; further, the shell board of the present invention does not Another plastic part needs to be added to protect the in-mold decoration technology provided on the male mold surface of the plastic part, but still has a multi-layered three-dimensional feeling, and the internal structure such as the fastening structure or the positioning post is still directly formed. The second surface of the transparent plastic part does not increase the overall thickness, material cost and process time of the product, thereby improving the process efficiency and increasing the convenience and practicability of the present invention.
