Method for manufacturing spectacle frame and forming mould thereof

Abstract

The invention discloses a method for manufacturing a spectacle frame, comprising the following steps of: machining one end plane of a mould to form two spectacle frame grooves with a basic shape of the spectacle frame, wherein the two spectacle frame grooves are communicated by a crossbeam groove, two pile head grooves are extent form two ends of the spectacle frame groove, and a hinge groove for accommodating a metal hinge is arranged on each pile head groove. Any metal hinge capable of 180-degree rotation is fixed in each hinge groove, raw materials of the spectacle frame are blended, are heated to form a melt material, then are injected into the spectacle frame grooves, simultaneously flow into the crossbeam groove, the pile head grooves and the hinge grooves, are then cooled and solidified, to form the spectacle frame which is integrally formed with the metal hinges. Two spectacle legs are respectively pivoted on the metal hinges. The method uses an injection molding technology of integration forming of the spectacle frame/ spectacle legs and the metal hinges, and can implement automation production, and reduction of management, personnel production cost. A finished product cannot appear traces any more, a product structure is more firmly, and product quality guarantee is increased. The invention further discloses a spectacle frame mould for implementing the manner.

Description

technical field [0001] The invention relates to the field of spectacle frame forming molds, in particular to a method for manufacturing spectacle frames and a forming mold thereof. Background technique [0002] Spectacles are usually composed of lenses and spectacle frames, and spectacle frames are composed of spectacle frames and temples connected by hinges, so that the spectacle legs can be folded when not in use. At present, the production process of spectacle frames in China First, the glasses frame is formed by injection molding process, and then one end of the hinge is heated and integrated into the frame / arms by manual means, and then the hinge is riveted. Due to the high-temperature fixing method of this kind of process, it is easy to cause damage to the frame, the defective rate is high and the efficiency is low. In addition, the production method of manually heating the hinge into the frame or temple is used, the production cost is too high, and it is subject to th...
