Description

Glasses legs and its manufacturing method {Temple and the manufacture method}

The present invention relates to a pair of spectacles and a method for manufacturing the same, and in particular to a pair of spectacles of a synthetic resin material having a core material of iron and a method for manufacturing the spectacles by injection three times to enable a very new and various design and It is about a pair of glasses.

As is well known, eyeglasses are frequently used as necessities of life and functionally occupy a large part in completing fashion with clothing, shoes and hair design as well as basic vision correction and blocking of sunlight (ultraviolet rays).

These glasses have been developed in a variety of ways, the conventional design of the glasses in addition to the way to diversify the shape of the spectacle by using a pattern, such as painting, transfer, coating, etc. on the frame of the eyeglasses including the glasses legs to design by design I finish it.

However, the design using such a shape has a very limited range of change, and thus it was difficult to add a new design except for the modification of the pattern. Accordingly, it was not enough to keep up with the tastes of the young generation who always pursue new designs. That's what caused me.

In particular, in the case of glasses legs, it was common to apply a design through colors on the outer surface of the conventional glasses legs, but the decoration of the method of adding color to these outer surfaces does not have a long life and is often peeled off or discolored and discolored, so that an effective design is effective. In recent years, in order to diversify the design, there has been a desire to change the design by inserting a core made of a material such as steel into a transparent or semi-transparent glasses leg. In the process, there was a drawback of complicated manufacturing, such as having to work in a state supported by a complicated device, and such a change in design would be difficult to escape from monotony.

The present invention devised in view of the above problems and necessity is to form the legs of the eyeglasses using an injection molding mold, but achieved a very innovative design improvement and diversification by three times injection and two times processing At the same time, it is an object of the present invention to provide a manufacturing method that enables the production to be simplified.

In order to complete the present invention, the first, second, and third injection molding and the injection molding using a general injection method, an injection machine for injecting the glasses legs, and a processing device for forming a pattern by penetrating or engraving the injected glasses legs. By completing the first and second machining in between, looking more specifically,

According to the present invention as described above, while having three textures or three colors of material coexist in one eyeglass leg and having unique patterns and characters, the glasses are solidly integrated as such materials. Compared to the conventional injection glasses, it is possible to produce glasses legs having a very unique and various design, and it is a useful invention to help the development of the glasses industry by widening the choice of the glasses for the consumer.

Hereinafter, a detailed and preferred embodiment for completing the spectacles of the present invention will be described in detail with reference to the accompanying drawings.

Lower mold preparation

The lower mold 10 has a lower injection recess 11 having a depth that is greater than half the thickness of the glasses legs to be manufactured and has a depth as small as a portion, and the hinge part of the lower injection recess 11 includes a part of the hinge. The hinge portion 12 was configured to seat the metal hinge 2 to be formed, and at the rear end, a hole 13 for inserting the iron core 3 for forming the curved earring portion 101 in the glasses leg 100. ) To be configured.

Primary upper mold preparation

The primary upper mold 20 is formed in a flat shape without grooves to form a set with the lower mold 10 so that injection molding is performed at a thickness equal to the depth of the lower injection recess 11 of the lower mold 10. It is.

Second upper mold preparation

The secondary upper mold 20 ′ has an upper injection recess 21 that is as deep as the remaining thickness of the glasses leg 100 formed in the lower mold 10. Therefore, when the lower injection groove 11 of the lower mold 10 and the upper injection groove 21 of the secondary upper mold 20 'abut, the shape is the same as that of the entire eyeglass leg 100 to be manufactured.

1st injection molding

The hinge 2 is inserted into the hinge portion 12 of the lower mold 10, the primary upper mold 20 is brought into close contact with each other, and then the injection molding is performed in the form of the lower injection recess 11 of the lower mold 10. The primary injection molding 1a having half the thickness of the glasses leg 100 to be manufactured is molded.

The iron core 3 is inserted into the portion to be the earring portion 101 of the glasses legs during the injection.

Primary processing

The primary injection molded product (1a) completed in the primary injection molding is processed, the pattern portion (1a-1) in the form of penetrating the widthwise edge or the middle portion of the primary injection molding (1a) in any shape and shape To form the primary workpiece 1b.

2nd injection molding

In the primary processing, the first processed product 1b in the state of processing the pattern portion 1a-1 is seated in the lower injection recess 11 of the lower mold 10, and then the second upper mold 20 ' The contact portion 1a-1 and the second upper mold 20 in the first processed product 1b by being in close contact with each other and injection molding using a material having a different color or a different texture from the first injection molding. The injection molding material is filled in the upper injection recess 21 formed in the ') to mold the secondary injection product 2a. Therefore, the secondary injection product 2a by the secondary injection has the same appearance as the glasses leg 100 to be manufactured.

Secondary processing

By processing the second injection molding (2a) to penetrate the thickness or by processing the pattern portion (2a-1) formed a letter or pattern in an engraved manner to make a secondary processed product (2b).

3rd injection molding

The secondary mold (2b) is seated on the lower mold (10), and the injection molding is carried out by using a material having a different material or color from that of the first and second injections. ).

Finishing

By processing the molded third injection molded product (3a) as described above to remove the burrs (burr) and to finish the production of the glasses leg 100 by smoothing and tidy appearance through a process such as gloss or coating.

Glasses frame assembly

The hinge 2 of the manufactured glass leg 100 is assembled with the hinge of the spectacle frame, and the iron core 3 is bent to create the earring part 101 to complete the manufacture of the glasses.

Glasses leg 100 of the present invention manufactured by such a manufacturing method is the inner surface side and the outer surface side is formed of a different material or a different color is integrated, and the material of the outer surface side is the primary injection molded product (1a) of the inner surface side It is integrated in the form of penetrating or wrapping part of the pattern, and also in the form of penetrating or engraved in the form of the letter or pattern of the processing portion of the material or color in the form of the other material is integrated.

When the injection is made using a different material or the same material when the injection is made of a material having a different color or texture, the material having three colors or three textures is a pattern shape unlike the general injection glasses. B can be integrated in the form of glasses legs.

In addition, the glasses legs manufactured by the method of the present invention have different materials or different colors about half of the thickness, and the three materials due to three injections are not separated from each other while being integrated by injection. Along with the hinge is to form a rigid pair of glasses.
