Spectacle frame forming mold and forming process

Abstract

The invention discloses a spectacle frame forming mold and forming process. The spectacle frame forming mold comprises a base, a positioning groove is formed in the middle of the upper surface of thebase, connecting threaded rods are fixedly arranged on the two sides of the upper surface of the base, the outer surfaces of the connecting threaded rods are slidably connected with connecting blocksthrough sliding through holes, the inner side surfaces of the connecting blocks are rotationally connected with a mold base through rotating rods, the outer side surface of the mold base is slidably connected to the inner side surfaces of the connecting threaded rods, the lower end of the outer surface of the mold base is slidably connected to the inner side surface of the positioning groove, spectacle leg mold grooves are formed in the upper surface of the mold base, first injection molding holes are formed in the front ends of the inner side surfaces of the spectacle leg mold grooves, a spectacle frame mold groove is formed in the lower surface of the mold base, and a second injection molding hole is formed in the rear side surface inside the spectacle frame mold groove. In this way, theconvenience and the stability of production and machining can be greatly improved, the production efficiency can be ensured, and the cost can be effectively reduced.

Description

technical field [0001] The invention relates to the field of spectacle frame technology, in particular to a spectacle frame molding die and a molding process thereof. Background technique [0002] In today's social life, with the increasing pressure of study and work, there are more and more people with myopia, and they need to match their eyes to see things clearly. Therefore, the demand for spectacle frames is also increasing, and spectacle frames are generally produced and processed. Injection molding is performed through a mold. [0003] However, there are some deficiencies in the use of some spectacle frame molding processes. For example, when the existing molding dies are in use, a single mold groove is opened on one side of the two mold seats, which can only produce the frame or the frame separately. The mirror legs are not only inefficient, but also cause a waste of mold space. At the same time, most of the existing molds are tightened and clamped by bolts, which is...

Problems solved by technology

[0003] However, there are some deficiencies in the use of some spectacle frame molding processes. For example, when the existing molding dies are in use, a single mold groove is opened on one side of the two mold seats, which can only produce the frame or the frame separately. The mirror legs are not only inefficient, but also cause a waste of mold space. At the same time, most of the existing molds are tightened and clamped by bolts, which is not only inconvenient to install and disassemble, but also not conducive to stable operation. The use effect is irrational and the use cost is high. , its mold structure and molding process need to be further improved
