Description

Manufacturing methods and thing of synthetic resin glasses leg which has the metal decorations face}

The present invention relates to a synthetic resin glasses leg, and more specifically, to strengthen the strength of the synthetic resin glasses legs to form a metal decorative pattern protruding to the reinforcement core of the metal material is inserted into the surface of the metal decorative pattern to the outside of the glasses legs The present invention relates to a method for manufacturing a synthetic resin glasses leg with a metal decorative surface to be exposed to the metal decorative pattern is formed on the glasses legs.

In general, glasses are widely used as an aid for eyesight, but recently, it is recognized as a fashion accessory that represents one's own personality, and glasses with colorful design and decoration are preferred.

The glasses leg is mounted on the wearer's ear and supports to distribute the load of the frame, and it is one of the important parts that gives aesthetics such as design and decoration of glasses.

On the other hand, synthetic resin glasses legs are manufactured by reinforcing the strength of the glasses legs by adding metal reinforcement cores to reinforce the strength. Synthetic resin glasses legs are decorated with glasses legs in various ways to give design and aesthetics.

That is, in order to enhance the design and aesthetics on the synthetic resin glasses legs, high gloss metal decorations are attached to the outside of the glasses legs, which are exposed to the outside, so that the decorations are not exposed to small impacts or hangs. There was a flaw that was easily damaged.

Therefore, in recent years, injection molding of semi-finished eyeglass legs with colored synthetic resin with color on the inside, and attaching metal decoration on the surface, and double-injecting the outer surface with transparent resin, the metal ornaments inside the eyeglass legs Buried spectacles are manufactured and used.

In other words, the double injection is carried out a plurality of injection process to complete one eyeglass leg to form a metal ornament on the synthetic resin leg to obtain a semi-finished eyeglass leg through the first injection process and the metal on the surface By attaching a decoration and injecting it again, one of the manufacturing method of the glasses leg to protect the metal ornament by placing the metal ornament inside the glasses leg so that the resin layer of the transparent body is formed on the surface of the metal ornament.

As the above-mentioned double injection, eyeglass legs in which metal ornaments are located inside the resin layer have excellent aesthetics and are prevented from being damaged by metal ornaments during use, but the manufacturing process is multi-stage and the failure rate is high, resulting in low productivity and low manufacturing cost. There was a flaw that was rising.

That is, in the past, the metal fittings are attached to the first-exjected semi-finished spectacles, which requires a highly skilled attachment technique by manually attaching a large number of metal fittings to the decorative position of the glasses legs. The metal fittings are easily bent or deformed due to the injection pressure due to the injection pressure during double injection, and this is done in the mold. Therefore, the injection molding is performed without the operator's knowledge and the injection molding is performed with the metal fittings damaged. Since the injection position of the metal fittings is moved by injection pressure and injection molding, the defect rate of the finished glasses legs is high.

The present invention has been made to improve the above-mentioned drawbacks as described above to form a plurality of metal ornaments having a thickness on the surface of the reinforcement core is put in order to reinforce the strength of the synthetic resin glasses leg to insert into the mold during the molding of the glasses legs Preparation of synthetic resin glasses with metal ornaments that can form a large number of metal ornaments at the same time by exposing the reinforcement core to the resin injected and exposing the surface of the decoration formed on the reinforcement core to the outside of the resin layer. Its purpose is to propose methods and objects.

In addition, the synthetic resin eyeglass legs according to the present invention omit the step of attaching a metal ornament to the eyeglass legs, the production process is simple, and a method and article for manufacturing a synthetic resin eyeglasses leg having a metal ornament without defects caused by the metal ornament are proposed. There is another object of the invention.

According to an aspect of the present invention,

Corrosion of the surface of the metal piece to form a height difference between the non-corrosive surface and the corrosion surface to form a reinforcing core in which the non-corrosive surface is formed as a decoration, and the injection mold is injected by inserting, but injected into the back of the reinforcing core and the thickness of the protruding decoration Resin is added to the reinforcement core is buried inside the injection resin by the surface of the decoration is located on the surface of the injected resin to be exposed to the outside, characterized in that to form a decorative portion of the glasses legs.

In the present invention as described above, the surface of the decoration formed on the reinforcement core during the injection molding of the eyeglass legs is exposed to the outside of the eyeglass legs to form a decoration by forming a plurality of protrusions at the reinforcement core to form a plurality of decorations at the same time There is an advantage in that productivity is excellent.

In addition, by plating or coloring the eyeglass cores, the color of the decorative body formed on the eyeglass legs can be varied, thereby obtaining an eyeglass leg with excellent aesthetics. There is an advantage that can remove the defects of the injection process is ejected and the decoration is spaced apart or part away.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
