Problems solved by technology

[0004] At present, there are many eye frames on the market that are formed by injection molding, but the structure of the traditional injection mold for eyeglass frames is to use four rows and four inclined roofs, but the structure of the demoulding structure is complicated. , high precision is required for processing and manufacturing, resulting in high cost and long manufacturing time, and the appearance of the spectacle frame after such a demoulding structure is demoulded is poor, often causing strain around the lens frame, which seriously affects the quality of the product

Embodiment Construction

[0028] The present invention will be further described below in conjunction with accompanying drawing:

[0029] Such as figure 1 Shown, a kind of spectacle frame mold structure, comprises front formwork 1 and rear formwork 2, is provided with front formwork 3, rear formwork 4 and The lens frame mold core 5 is provided between the lens frame mold core 5 and the rear template 4. When the mold is opened, the lens frame mold core 5 can make the lens frame mold core 5 move in a straight line and then rotate to get out of the spectacle frame 100. When opening the mold, the demoulding device 6 makes the lens frame mold core 5 move linearly forward. When moving to the set distance, the demoulding device 6 makes the lens frame mold core 5 rotate relative to the spectacle frame 100, and the lens frame mold core 5. Warpage occurs during the rotation process. Due to the elasticity of the injection-molded spectacle frame 100, the spectacle frame 100 pops out and is demoulded. The spectacl...

Abstract

The invention discloses a spectacle frame mold structure. The spectacle frame mold structure comprises a front mold frame (1) and a rear mold frame (2), and is characterized in that a front mold plate (3), a rear mold plate (4) and an eyeglass frame mold core (5) which are used for forming a spectacle frame are arranged between the front mold frame (1) and the rear mold frame (2), and a demolding device (6) used for enabling the eyeglass frame mold core (5) to move linearly and then rotate to be demolded out of the spectacle frame (100) during mold disassembling is arranged between the eyeglass frame mold core (5) and the rear mold plate (4). The spectacle frame mold structure is simple and low in cost, the spectacle frame after injection molding has no any damage after demolding, and the quality is stable.

Description

[0001] 【Technical field】 [0002] The invention relates to a spectacle frame mold structure. [0003] 【Background technique】 [0004] At present, there are many eye frames on the market that are formed by injection molding, but the traditional injection mold for eyeglass frames uses a structure of four rows and four inclined roofs for the demoulding of the spectacle frame, but such a demoulding structure is complicated , Processing and manufacturing require high precision, resulting in high cost and long manufacturing time, and the appearance of the spectacle frame after demoulding of such a demoulding structure is poor, often causing strain around the lens frame, seriously affecting the quality of the product. [0005] Therefore, the present invention arises at the historic moment. [0006] 【Content of invention】 [0007] The object of the present invention is to overcome the deficiencies of the prior art, and provide a mold structure of the spectacle frame with simple struc...
