The utility model discloses a technical scheme that thin slice etching mould adopted is:

a sheet etching die comprises a base, wherein a groove is formed in the base, a cutter is arranged in the groove, and the cutter forms a pattern to be punched; the cutter cross-section includes first blade, second blade and cutter body in proper order by top to bottom, the contained angle of first blade is less than the contained angle of second blade.

Preferably, the first blade tip includes a first inclined surface and a second inclined surface, an included angle between the first inclined surface and the vertical direction is 5 degrees to 10 degrees, and an included angle between the second inclined surface and the vertical direction is 15 degrees to 25 degrees; the second blade point comprises a third inclined surface, and the included angle range of the third inclined surface and the vertical direction is 25-40 degrees.

Preferably, the cross section of the cutter body is of a trapezoidal structure, and the included angle between two side edges of the cutter body and the vertical direction is 5-10 degrees.

Preferably, the first blade, the second blade and the cutter body are all transited through a fillet.

Preferably, the height of the cutting knife is 1-1.5 mm.

The utility model discloses a thin slice etching mould's beneficial effect is: the base is provided with a groove, the cutter is arranged in the groove, and the cutter forms a pattern required to be punched. The section of the cutter sequentially comprises a first blade, a second blade and a cutter body from top to bottom, and the included angle of the first blade is smaller than that of the second blade. The blade part of the cutter is cut into multiple stages, and the first blade at the top has a smaller inner angle, so that the first blade is relatively sharp, and quick and complete punching can be quickly realized to ensure good punching precision. The second blade has a larger inner angle, so that the thickness of the second blade is larger than that of the first blade, and the second blade is used for quickly separating the gaps punched by the first blade; meanwhile, the wider thickness can provide stronger supporting force for the bottom of the first blade edge, so that the first blade edge is prevented from being broken, and the service life of the first blade edge is prolonged.

Drawings

FIG. 1 is a schematic structural diagram of a wafer etching mold according to the present invention;

fig. 2 is a cross-sectional view of the slice etching die cutter of the present invention.

Detailed Description

The invention will be further elucidated and described with reference to the following embodiments and drawings in which:

referring to fig. 1 and 2, a wafer etching mold includes a base 10.

The base 10 is provided with a groove 20, the inside of the groove 20 is provided with a cutter 30, and the cutter 30 forms a pattern to be punched. The section of the cutter 30 sequentially comprises a first blade 31, a second blade 32 and a cutter body 33 from top to bottom, and the included angle of the first blade 31 is smaller than that of the second blade 32.

The blade part of the cutter 30 is cut into multiple stages, and the first blade 31 at the top has a smaller inner angle, so that the first blade 31 is relatively sharp, and quick and complete punching can be quickly realized to ensure good punching precision. The second blade 32 has a larger inner angle, so that the thickness of the second blade 32 is larger than that of the first blade 31, and the second blade is used for quickly separating the gap punched by the first blade 31; meanwhile, the wider thickness can provide stronger supporting force for the bottom of the first blade edge 31, so that the first blade edge 31 is prevented from being broken, and the service life of the first blade edge is prolonged.

The knife 30 in this example is 1-1.5mm in height and is used primarily for die cutting sheet material.

Preferably, the first blade edge 31 includes a first inclined surface 311 and a second inclined surface 312, the first inclined surface 311 is inclined at an angle ranging from 5 ° to 10 ° with respect to the vertical direction, and the second inclined surface 312 is inclined at an angle ranging from 15 ° to 25 ° with respect to the vertical direction. The inclined planes with different angles of the first blade edge 31 are utilized to lead the glue overflow phenomenon of the punching edge to have directionality, and the glue overflow phenomenon is guided to the direction of waste materials, so that the precision of the workpiece is improved.
