Document Type and Number:
WIPO Patent Application WO/2022/048218
Kind Code:
A1
Abstract:
Discloses in the present invention is an spectacle frame manufacturing method and a molding die. The molding die comprises a base. An equipment box is fixedly connected to the top of the base; a frame is fixedly connected to the top of the equipment box; a lower die is fixedly connected to the bottom of an inner cavity of the frame; an air cylinder is fixedly connected to the top of the frame; and the bottom of an output end of an air cylinder penetrates through the inner cavity of the frame and is fixedly connected to an upper die. By providing the base, the equipment box, the frame, the lower die, the air cylinder, the upper die, heat dissipation tubes, a fan, a die cavity, heat dissipation boxes, water pumps, first connection tubes, semiconductor refrigeration sheets, second connection tubes, heat conduction rods, a motor, a first rotating rod, a first gear, second rotating rods, second gears, and stirring rods, the present invention can accelerate cooling of a workpiece in multiple manners, thus improving the molding speed of the workpiece, and solving the problem of slower molding speed of existing spectacle frame molding dies. The spectacle frame molding die has an advantage of fast molding speed.
