Special-shaped cutter mold and preparation method thereof

Abstract

The invention discloses a special-shaped cutter mold and a preparation method thereof. The special-shaped cutter mold comprises a cutter mold base body, mold cavities and blades; the mold cavities arearranged on the cutter mold base body; two adjacent mold cavities of the same row or column are marked as a first mold cavity and a second mold cavities correspondingly, wherein the first mold cavitycomprises a first linear mold cavity and a first non-linear mold cavity, the second mold cavity comprises a second linear mold cavity and a second non-linear mold cavity, the first linear mold cavityand the second linear mold cavity are overlapped, and the first non-linear mold cavity is connected to the second non-linear mold cavity left and right; the two opposite mold cavities of different rows or columns are marked as a first mold cavity and a third mold cavity correspondingly, wherein the third mold cavity comprises a third linear mold cavity and a third non-linear mold cavity, and a gap is formed between the first linear mold cavity and the third non-linear mold cavity; and the blades are arranged in the mold cavities. According to the special-shaped cutter mold, the common cutterdesign is adopted among the mold cavities, so that the use quantity of the blades is greatly reduced, then the manufacturing cost of the cutter mold is reduced, the number of the blades is reduced, the cutting pressure is correspondingly reduced, and the product reject ratio is reduced.

Description

technical field [0001] The invention relates to the technical field of cutting dies, in particular to a special-shaped cutting die and a preparation method thereof. Background technique [0002] With the continuous development of mobile phone full-screen technology, special-shaped solutions have sprung up, and major manufacturers are competing to apply them. Polarizers, one of the three major components of liquid crystal displays, are also looking for mature special-shaped production solutions. The traditional special-shaped polarizer production method is to first cut into rectangular pieces and then use CNC equipment for processing. This kind of solution has a large margin for edging and low production efficiency. A solution for forming small shaped pieces. [0003] However, the existing special-shaped die cutting method has the following defects: as figure 1 As shown, the existing special-shaped die design adopts a mesh structure, that is, there is a gap of 4 to 5 mm be...

Problems solved by technology

The traditional special-shaped polarizer production method is to first cut into rectangular pieces and then use CNC equipment for processing. This kind of solution has a large margin for edging and low production efficiency. The solution of forming special-shaped small pieces

[0003] However, the existing special-shaped die cutting method has the following defects: as figure 1 As shown, the existing special-shaped die design adopts a mesh structure, that is, there is a gap of 4 to 5 mm between the blade and the blade, which will reduce the material utilization rate during cutting; in addition, the die blade generally adopts Zhongshan mirror imported from Japan Knives are expensive, the blades of the current scheme cannot be reasonably utilized, and the cost of the dies increases; moreover, there is a certain proportional relationship between the cutting pressure and the total meter of blades, the more blades are used, the greater the pressure required for cutting, and the The greater the cutting pressure, the higher the defective rate of the product
