Abstract

The invention discloses an extrusion die for producing a multi-layer superfine line plate. The extrusion die comprises a first die core, a second die core, a third die core and a fourth die core which are sequentially and fixedly connected from right to left and are columnar. According to the extrusion die for producing the multi-layer superfine line plate, direct production of a superfine line semi-finished product with a layering effect is achieved through combination of the four die cores, and the defect that an existing single-layer line superposition hot-pressed product are lack of layering sense and stereoscopic sense is overcome; the appearance quality and the market competitiveness of the product are effectively improved; and the extrusion die has the characteristics of a stable structure, convenient production, high quality, exquisite product and the like.

Description

technical field [0001] The invention relates to the technical field of plastic plate production, in particular to an extrusion die for producing multi-layer ultra-fine line plates. Background technique [0002] Cellulose acetate sheets are widely used in the production of eyeglass frames and accessories, and the production of cellulose acetate sheets is divided into extrusion molding and thermoforming. Among them, thermoforming requires the production of semi-finished products of various colors and shapes. Existing molds cannot produce multi-layer ultra-fine line cylindrical semi-finished products, so the method of superimposing single-layer lines has to be adopted, resulting in the lack of layering and three-dimensionality of the pattern of the hot-pressed plate. Contents of the invention [0003] The object of the present invention is to provide an extrusion die for producing multi-layer ultra-fine wire sheets, so as to solve the problems raised in the above-mentioned ba...
