Description
The present invention relates to a method and an apparatus for manufacturing a spectacle leg, and more particularly, to a method and apparatus for manufacturing a spectacle leg that can reduce the thickness of a spectacle leg by applying an insert injection technique of a metal core.
In general, the glasses should be comfortable to wear when wearing on the user's face, and in order to make the glasses feel good, the glasses legs should be curved according to the contours of the wearer's face, It should be able to exert sufficient tightening force so that it does not flow easily.
In order to prevent the eyeglass legs from pressing down on the wearer's face in order to prevent the eyeglasses legs from touching the wearer's face as much as possible, Keep in close contact with your face.
Therefore, the function of reducing the feeling of pressure of the eyeglass legs and the function of preventing the eyeglass legs from falling off easily from the face require the shape of the opposite eyeglasses legs, so that the manufacture of the eyeglass legs It is difficult to find the answer although it is still difficult to find it.
In order to lighten the weight of the glasses, the glass legs made of resin reinforce the strength of the glasses legs and the iron cores are inserted into the ear pieces of the glasses legs so that the glasses legs come into close contact with the wearer's face.
Conventionally, when an eyeglass leg into which an iron core is inserted is injection molded, an iron core is inserted by a shooting method.
However, injection-type injection molding is possible when the thickness and width of the eyeglass legs are wide, but when the eyeglass legs are slim, the thickness and the width of the eyeglass legs are narrow, And thus it is difficult and difficult to manufacture a slim leg having an iron core inserted therein.
