Description

Die cutting die and die cutting machine

Technical Field

The utility model relates to a cross cutting product processing equipment technical field specifically is a cross cutting mould and cross cutting machine.

Background

With the rapid development of the electronic industry, especially the product range of electronic products is continuously expanded, the application of die cutting processing in the auxiliary material of the electronic product is more and more extensive. The material for die cutting is rubber, single-sided tape, double-sided tape, foam, plastic, vinyl, silicon, metal thin tape, metal sheet, optical film, protective film, gauze, hot melt adhesive tape, silica gel, etc. However, in the existing die cutting machine, since the punching end surface of the die is smooth and planar, broken filaments or burrs are easily generated in the die cutting and punching process of processing over-soft or over-hard materials, and the broken filaments or burrs can be adhered to the die cutting machine, so that the subsequent die cutting and punching is affected, and the yield of raw materials is low.

SUMMERY OF THE UTILITY MODEL

To the easy problem that produces broken filament, flock in current cross cutting die-punching in-process and lead to raw and other materials yield low, the utility model provides a cross cutting mould, its cross cutting die-punching in-process is difficult for producing broken filament, flock, makes raw and other materials yield higher. The utility model also provides a cross cutting machine.

The technical scheme is as follows: the utility model provides a die cutting mould, its is including last mould and the lower mould that is used for die-cut composite insulation material, its characterized in that: a groove is formed in the inner part of the end face of the punching end of the upper die, and the cross section of the punching end is in an inverted right trapezoid shape or an inverted isosceles trapezoid shape;

it is further characterized in that: the upper end surface of the lower die is provided with a through hole corresponding to the groove of the upper die, and the upper end surface of the lower die is matched with the end surface of the punching end;

the included angle between the side wall of the punching end and the vertical direction is 30-60 degrees;

the thickness of the end face of the punching end is 0.5-5 mm;

the composite insulating material is a PC or PET material;

the upper die is made of steel materials;

the utility model provides a cross cutting machine which characterized in that: the die-cutting machine comprises the upper die and the lower die, wherein the upper die and the lower die are respectively arranged on the die-cutting machine, and the end surface of the die-cutting end corresponds to the upper end surface of the lower die.

After the die cutting die with the structure is adopted, the groove is formed in the end face of the punching end of the upper die, so that the contact surface between the upper die and the composite insulating material is small, the punching pressure is increased, broken filaments or broken bits are not easy to generate, the yield of the die cutting punching is improved, meanwhile, the cross section of the punching end of the inverted right trapezoid or the inverted isosceles trapezoid can further increase the punching pressure, and the yield of the die cutting punching is further improved.

Detailed Description

As shown in fig. 1 to 3, a die cutting mold includes an upper mold 1 and a lower mold 2 (not shown) for die cutting a composite insulating material, which is a PC or PET material. Wherein go up mould 1 and be the L type, go up mould 1 and be the steel material, it has recess 12 to open on the terminal surface of die-cut end 11 of mould 1 to go up, and the thickness of the terminal surface of die-cut end 11 is 0.5~5 mm. The section of the punching end 11 is in an inverted right trapezoid or an inverted isosceles trapezoid. Preferably, the included angle a between the side wall of the punching end 11 and the vertical direction is 30-60 degrees. When the composite insulating material is punched by the upper die 1, because the groove 12 is formed in the end face of the punching end 11 of the upper die 1, the contact surface of the upper die 1 and the composite insulating material becomes a square contact surface, the contact area is reduced, the punching pressure is increased, thereby the blank wire or the blank scrap is not easy to generate during punching of the material, the yield of punching of die cutting is improved, the cross section of the punching end 11 adopting the inverted right trapezoid or the isosceles trapezoid can further increase the punching pressure, and the cutting yield is further improved. Meanwhile, a small amount of broken filaments or shavings generated at the punching end face 11 can be stored in the groove 12 during punching, so that uniform processing is facilitated.

As shown in fig. 4, the upper die 1 corresponding to the above structure is provided with a lower die 2, and the specific structure thereof is that a through hole 22 matched with the groove 12 of the upper die 1 is provided on an upper end surface 21 of the lower die 2, the through hole 22 is a square hole or a rectangular hole, and the upper end surface 21 of the lower die 2 is matched with the end surface 11 of the punching end 12. Through the setting of through-hole 22 for when going up die mould 1 die-cut downwards, a small amount of broken silks or the flock that produce also can leak from through-hole 22 and fall, convenient unified processing.

The die-cutting machine (not shown in the figure) is provided with the upper die 1 and the lower die 2 which are in the structure, the upper end face 21 of the lower die 2 corresponds to the end face of the die-cutting end 11, broken filaments and broken bits are not easy to generate when die-cutting and die-cutting are carried out by the die-cutting machine, and the yield of cut materials is higher.

The above description is only for the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
