Abstract

The utility model relates to the field of processing of release films, and discloses a positioning hole cutting die free of waste discharge, which comprises a cutting board and a cutter; the cutter is arranged on the cutter plate; the cutting knife is in an unclosed earphone shape and comprises an arc-shaped blade and two linear blades connected with the end points of the arc-shaped blade. The central angle of the circular arc blade is at least 180 degrees. The two linear blades are parallel to each other. The cutter is not closed and makes the type membrane after the cross cutting not have the waste material to produce, and the membrane on the locating hole still remains at the normal position, but has surely cut out the locating hole shape, disposes the locating pin on the tool when using and can push away the useless membrane of this position, and the locating hole still plays the positioning action, and the waste material is stayed the locating hole position, avoids the waste material to drop, removes the waste discharge step from, has improved production efficiency.

Description

Positioning hole cutting die free of waste discharge

Technical Field

The utility model relates to a from type membrane processing cutting die, in particular to exempt from locating hole cutting die of row's waste material.

Background

The positioning holes on the release film are subjected to die cutting, the cutting die for die cutting needs to discharge cut waste materials after the die cutting is finished, the original wood board cutting die needs to be manually subjected to waste discharge operation, and the production efficiency is low; practical five metals blanking steel mould, it is with high costs, need regularly clear up the grinding apparatus in long-term production process and arrange the waste hole, prevent to arrange the waste hole jam.

SUMMERY OF THE UTILITY MODEL

The utility model provides a technical problem provide a exempt from locating hole cutting die of row's waste material, can not produce the waste material in the course of working, remove the process of wasting discharge from, improve production efficiency.

The utility model provides a technical scheme that its technical problem adopted is: a positioning hole cutting die free of waste discharging comprises a cutting board and a cutter; the cutter is arranged on the cutter plate; the cutting knife is in an unclosed earphone shape and comprises an arc-shaped blade and two linear blades connected with the end points of the arc-shaped blade. The cutter is not closed, so that no waste material is generated in the die-cut release film, the film on the positioning hole is still kept in the original position, but the shape of the positioning hole is cut, the positioning needle on the jig is configured when the die-cut release film is used, the waste film at the position can be ejected, and the positioning hole still plays a positioning role.

Further, the method comprises the following steps: the central angle of the circular arc blade is at least 180 degrees. The area of the positioning hole on the release film can meet the use requirement when the central angle exceeds 180 degrees; the larger the central angle, the closer the circular arc blade cuts a shape that is to a full circle.

Further, the method comprises the following steps: the two linear blades are parallel to each other. The parallel linear blades enable the cutter to have no closed shape, and waste materials are prevented from being generated during die cutting.

Labeled as: 100. a cutting board; 200. a cutter; 210. a circular arc blade; 220. a linear blade; 300. positioning a jig; 310. a positioning pin; 400. products to be pasted; 500. a release film; 510. and (7) positioning the holes.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1, a pilot hole cutting die without discharging waste material comprises a cutting board 100 and a cutter 200; the cutter 200 is arranged on the cutter plate 100; the cutter 200 is in the shape of an unclosed earphone, and the cutter 200 comprises an arc-shaped blade and two linear blades connected with the end points of the arc-shaped blade. For convenient use, need be provided with locating hole 510 on the release film 500, locating hole 510 cuts through cutter 200, and cutter 200 is not closed for the waste material of cutting still stays the normal position, avoids the waste material to drop, removes the waste discharge step from, improves production efficiency.

On the basis of the above, as shown in fig. 1, the central angle of the circular arc-shaped blade is at least 180 °. The central angle of the circular arc blade can be any angle between 180 degrees and 360 degrees, and the central angle can be 190 degrees, 250 degrees, 300 degrees and the like. The larger the central angle, the closer the shape cut by the circular arc blade is to a full circle.

On the basis of the above, as shown in fig. 1, the two linear blades are parallel to each other.

As shown in fig. 2, after the release film 500 is processed by the cutting die, the waste film is retained on the positioning hole 510, and during actual use, the positioning pin 310 on the positioning fixture 300 will push the waste film at the position of the positioning hole 510 open, so that the positioning and the normal use of the release film 500 are not affected.

The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
