TWI288085B - Molded article capable of refracting or reflecting light and the die used thereof - Google Patents

Abstract

This invention is to provide a molded article capable of refracting or reflecting light and the die used thereof. In the cavity of the male and the female dies, an etching process is performed to form symmetrical three-dimensional embossments (etching patterns) of different densities and shapes. The dies are then used in the plastic injection molding process with colored or colorless transparent raw material to produce molded articles which have the symmetrical three-dimensional embossments of different densities and shapes on their surfaces. These embossments may result in light refraction, reflection or polarization phenomenon between the incidence and emergence surfaces, resulting in special gloss and visual effects.

Description

1288085 IX. Description of the Invention: The invention relates to a molded article and a mold thereof, and more particularly to a molding with light refraction or reflection which can produce special gloss and visual effects by a pattern. Items and their molds. [Prior Art] According to the general method of manufacturing a molded article having a surface pattern, there are two methods, one of which is formed by etching on the surface of the mold to form a suitable bite flower (last name pattern), and the mold is manufactured. The surface of the plastic article has a desired pattern, and the other is to form a molded semi-finished product, and then the semi-finished product is processed by a surname to form a desired pattern on the surface. However, although the molded articles of the conventional ones can have three-dimensional or double-sided three-dimensional or flat patterns, the patterns are independent and do not have the functions of light refraction and reflection, so they are monotonous and cannot exhibit a laser-like gloss. Degree, visual effect and texture. SUMMARY OF THE INVENTION The present inventors have in view of this, thinking and the idea of invention creation, actively and continuously researching and improving in the spirit of perseverance and perseverance, and through various discussions and trial sample tests, and multiple corrections. Improvements have been made in the present invention. The invention provides a difficult material for refraction or reflection of a secret light and a mold thereof, which are formed on the surface of the cavity of the male and female molds in a side manner, and form a relative shape of three different shapes and densities on the surface of the cavity of the male and female molds. Bite the flower (last name pattern), and use the above-mentioned mold to form a molded article by plastic injection processing with a colored or colorless transparent material, and the surface of the plastic article has a pattern corresponding to the bite of the surface of the male and female molds; &, the reaction of the molded article to light will be reflected by different light lines and depth, and the light refraction of the human face is 5 and the reflection or polarized light is the same, _ not _-like the brightness of the plane or the reading limb Degree and visual effects. The main purpose of the present invention is to distinguish the characteristics of the fine-faced lion-turned material with the corresponding pattern of the double-sided shape and the density, and the light-clear and reflective side, which exhibits a laser-like gloss, visual effect and M. To enhance the value and use of molded articles. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following, the preferred embodiments of the present invention will be described in detail with reference to the following: FIG. 1 is a schematic view of the male mold of the present invention, and a plan view of the mother side of the second figure and a third diagram of the present invention. As shown in the plan view of the molded article, it is attached to the surface of the mold (10), (20) of the mold, and the surface of the mold (11), (21) is exposed by exposure or chemical development, in the male and female molds (1〇) ), (20) the cavity (11), (21) surface forming different shapes and densities of the relative stereo bite (rice pattern X111), (211), and the depth of the bite (m), (2n) And the shape can be freely designed and changed as needed. By using the above-mentioned mold, a transparent or translucent molded article (30) is formed by transparent injection of a colored or colorless transparent material, so that the surface of both sides of the molded article (30) has a male and female (10), (20) the cavity pattern (11), (21) the surface biting flower (ln), the corresponding pattern of the (211) (31); and the molded article (30) reacts to light due to the different patterns on both sides (31) and the pattern (31) depth, which exhibits different light refraction and reflection or polarization reaction between the light incident surface and the exit surface, and achieves gloss and visual effects different from the plane or three-dimensional pattern of the general molded article. From the above specific embodiments, it can be analyzed that the molded article of the present invention (for example) can be matched with the corresponding pattern (31) of different shapes and densities on both sides by the characteristics of the transparent material, and the 1288085 has special light refraction. And the reflection effect 'the molded article (30) exhibits a laser-like gloss, visual effect and texture, thereby achieving the value and use of the molded article (30), and the mold of the present invention is easy to process, Additional manufacturing costs are required. In summary, it is known that the present invention has industrial applicability and progress, and the present invention is not found in any injury, but also lies in the dirty, the provisions of the method of filling the law, and the invention of the invention patent application, the review of the review committee Yu Lilin.
