Embodiment 1

[0017] In the embodiment of the present invention, there is provided a process method of directly molding glasses with chip pits without increasing the machining cost. The glasses include spectacle legs 1, hinges 2, front bezel 3, pipe 4, middle bridge 5, piece pit 6, crown head 7 and front bezel clip 8, such as figure 1 shown.

[0018] In order to achieve the above-mentioned purpose, firstly, the dummy 9 is implanted: the dummy 9 made of steel with the shape of the lens is pre-implanted in the mold cavity before molding. During die-casting, chip pits are formed directly. Such as figure 2 shown.

[0019] The concave structure of the crater forms an undercut after molding, which determines the problem that the glasses cannot be demolded after the crater is formed directly on the mold. In order to solve the above problems, secondly, as a replaceable part, the dummy 9 is precisely positioned in the mold cavity through the positioning hole, which ensures the dimensional accur...

Abstract

The invention discloses a direct compression molding process method for lens pits of liquid metal spectacles. The method includes the following steps that, before molding, fake lenses in the shape of a lens are implanted in a mold cavity of a mold in advance; clamping ports for breaking off front rings are arranged in the positions, close to end pieces, of the front rings of the liquid metal spectacles, and during compression molding, the fake lenses can directly form the lens pits; the fake lenses are accurately positioned in the mold as accessories, and when a casting goes out of the mold, the fake lenses and the casting spectacles go out of the mold together; and the positions of the clamping ports are opened, the whole fake lenses are released from the front rings, the lens pits can be obtained when the fake lenses smoothly disengage from the front rings, and the fake lenses can be repeatedly utilized. By means of the direct compression molding process method, the liquid metal spectacles directly form the lens pits of lenses through a direct compression molding method, machining is not needed, high-efficiency and high-quality batch production can be achieved, and a good technical basis is provided for application of liquid metal in the industry of spectacles.

Description

technical field [0001] The invention relates to the technical field of spectacles manufacturing, in particular to a process method for direct die-casting of lens pits of liquid metal spectacles, and is especially suitable for liquid metal spectacles frames with complete eye socket shapes. Background technique [0002] Liquid metal can be molded by die-casting. It has the characteristics of high strength, high hardness, and strong corrosion resistance. It is very suitable for use as a material for glasses. In recent years, there have been patent application numbers 201410831659.1, 201410833220.2, and 201410833227.4, all of which have proposed the use of liquid metal in the glasses industry, but they cannot provide effective production methods for the characteristics of materials and glasses. [0003] Since liquid metal has no plastic deformation ability, the chip pit cannot be formed by car pitting and then bending like ordinary titanium glasses; after forming and then proces...
