Graph printing injection molding method

Abstract

The invention provides a graph printing injection molding method. The graph printing injection molding method is characterized in that after a bottom mould formed by injection molding is taken, a graph layer is printed on the upper surface of the bottom mould; a light-transmittable surface mould is formed on the upper surface of the bottom mould printed with the graph layer by injection molding through a mould, so that the surface mould can be molded on the bottom mould and the graph layer of the bottom mould can be displayed in the surface mould.

Description

technical field

[0001] The invention relates to a graphic printing injection molding method which enables the printed graphics to be molded in a model combined with two injection moldings, so that the model has high bonding strength and the graphics are not damaged. Background technique

[0002] Due to the advancement of printing technology, today's printing equipment can print on the upper surface of soft materials to be printed (such as paper, cloth or other textiles) or hard materials to be printed (such as plastic, metal, glass or ceramics), making it widely used In various industrial fields, to increase the visual effect of the appearance of the product.

[0003] However, when the above-mentioned printing operation is directly printed on the surface of the object to be printed, the printed pattern or text will appear on the surface of the object to be printed in an embossed state. Although it has a three-dimensional effect, it is often used. Abrasion, scratches or even...

Embodiment Construction

[0017] Please refer to Figures 1-3, which is an embodiment of a graphic printing injection molding method of the present invention, which includes the following steps:

[0018] Step a: Take a bottom mold 1 after injection molding;

[0019] Step b: printing a graphic layer 2 on the upper surface of the bottom mold 1;

[0020] Step c: using a mold on the upper surface of the bottom mold 1 printed with the graphic layer 2, injection molding a light-permeable surface mold 3, so that the surface mold 3 can be molded on the bottom mold 1, and the bottom mold The graphic layer 2 of the mold 1 can be displayed in the surface mold 3 .

[0021] In practice, the bottom mold 1 is transparent or opaque, and the graphic layer 2 includes patterns or characters.

[0022] In this way, as shown in Figures 2 and 3, after the surface mold 3 is directly injection-molded on the bottom mold 1, a finished product can be formed, and the graphic layer 2 can pass through light as if it is wrapped in t...
