Abstract

The invention discloses an upper mold device for a lens frame bending forming machine. According to the technical scheme, the upper mold device for the lens frame bending forming machine comprises twosets of upper mold seats connected to the lens frame forming machine and moving up and down relative to the lens frame forming machine, lifting cylinders connected between the lens frame forming machine and the upper mold base and driving the upper mold seats to move up and down and two upper modules connected to the upper mold bases and separately abutting against a lens frame; the two sets of upper mold seats are symmetrically arranged and position a leans frame positioning assembly of the lens frame relative to the positions of the upper modules, an installation adjustment assembly is arranged between the upper modules and the upper mold bases, an upper lens frame beam mold abutting against and extruding a lens frame beam is arranged between the two upper modules, and the upper mold seats are provided with driving extrusion assembles which drives the upper lens frame beam mold to move down and extrude and form the lens frame beam. The upper mold device for the lens frame bending forming machine can realize the bending and forming of the lens frame with different bending angles, improve the accuracy of the bending and forming of the lens frame, and improve the bending and forming efficiency of the lens frame.

Description

technical field [0001] The invention relates to the field of mirror frame processing, in particular to an upper mold device of a mirror frame bending forming machine. Background technique [0002] Existing eyes mainly comprise spectacle frame, spectacle pin, eyeglass; And spectacle frame generally comprises two spectacle frames, the bridge of the nose that is arranged between two spectacle frames, the spectacle frame bridge that connects two spectacle frames. [0003] After the injection molding of the frame, the frame is generally flat or has a certain curvature. In order to adapt the spectacle frame to the contour of the human face, it is necessary to adjust the frame by bending and forming. After the beam of the frame is bent at a certain angle, the frame is adapted to the contour of the face to ensure that the two lens frames are compatible with the eyes of the human body. [0004] Existing mirror frame bending is generally performed by preheating the mirror frame and t...
