Description

Cutting Dies {CUTTING DIE}

The present invention can cut a film having a hard coat layer, such as a three-dimensional molded article (curved molded article, bent molded article) formed from a sheet or a film, a press-molded article, an injection molded article, or an organic EL or a solar cell protective film according to the three-dimensional contour. When the present invention relates to a cutting die capable of fine and accurate cutting process.

BACKGROUND ART Conventionally, a technique for punching a three-dimensional molded article made of plastic or the like is known (see Patent Document 1). In this kind of technique, as shown in Fig. 16 (A), a blade tip e is formed on a band-shaped blade (thomson blade) 81, and a wedge-shaped cutout is formed on the opposite side of the blade (sword side). (82) is formed. As shown in FIG. 16 (B), the blade tip e and the blade P of the band-shaped blade 81 are bent to be concentric arcs and attached to the base 83. In the receiving member 84, unevenness corresponding to the curved shape of the blade tip e of the band-shaped blade 81 is formed. Then, the base 83 is attached to the lower surface plate 85 and the receiving member 84 is attached to the upper surface plate 86 to cut the curved molded object or the bent molded product to be cut.

Patent Document 1: JP-A 2006-15445

However, the above cutting technique is inconvenient to adjust the position of the base 83 to which the band-shaped blade 81 is attached, and the receiving member 85, so that the cutting object cannot be cut into an accurate shape or is not cut. There is a part. For this reason, there exists a problem which should give up fine cutting from the beginning.

In addition, with the above cutting technique, it is impossible to bend the band-shaped blade 81 finely, and thus fine cutting cannot be performed, and the entire band-shaped blade 81 is deformed due to the cutout 82, so that accurate cutting can be performed. There is a problem that can not be broken and the band-shaped blade 81 is broken.

An object of the present invention is to form a three-dimensional molded article (curved molded article, bent molded article), press-molded article, injection molded article, or a film having a hard coat layer such as an organic EL or a solar cell protective film formed of a sheet or a film according to the three-dimensional contour. When cutting, it is to provide a cutting die capable of fine and accurate cutting process.

This invention makes the following structure a summary.

(1) A cutting die for cutting a three-dimensional body having a cutting blade disposed on one side of the upper plate and a lower surface plate and a receiving member disposed on the other side.
The cutting blade has a blade at the tip of the metal block, is formed by cutting so that the tip height of the blade has a different height depending on the portion of the blade tip,
The receiving member has an unevenness corresponding to the height of the tip of each part of the cutting blade,
A first jig for setting the first base, a second jig for setting the second base, and a guide member for allowing the first jig and the second jig to slide only in the vertical direction;
At least one side of the first jig and the second jig is a planar member, and an elastic sheet is attached between the planar member and the base.
(2) a first base having the cutting edge, a second base having the receiving member, and a guide member for slidably sliding the first base and the second base only in the vertical direction. Cutting die.

By this elastic sheet, the contact pressure between the tip of the cutting blade and the receiving member can be alleviated by elasticity, or the gap error between the tip of the cutting blade and the relief of the receiving member can be absorbed.

Butyl rubber (IIR), ethylene propylene rubber (EPM, EPDM), urethane rubber (U), silicone rubber (Q), chloro sulfonated rubber (CSM), chlorinated polyethylene (CM), acrylic rubber (ACM) as an elastic sheet And non-diene rubbers such as epichlorohydrin rubber (CO, ECO), fluororubber (FKM) and the like can be used.

The elastic sheet can be used as a magnet sheet having a self-adsorption effect on one or both surfaces. For example, when the elastic sheet is a magnet sheet having a self-adsorbing action on both sides, (a) one side of the magnet sheet is self-adsorbed to the first base and the other side is self-adsorbed to the first jig, or ( b) One side of the magnet sheet may be configured to self-adsorb on the second base and the other side is self-adsorbed on the second jig.

Or when the elastic sheet is a magnet sheet having a self-adsorbing action on one side, (c) one side of the magnet sheet is adhered to the first base and the other side is self-adsorbed to the first jig, and (d) one of the magnet sheets The side is adhered to the second base and the other side is self-adsorbed to the second jig, (e) one side of the magnet sheet is adhered to the first jig and the other side is self-adsorbed to the first base, (f) the magnet sheet One side of the may be bonded to the second jig and the other side may be configured to self-adsorb on the second base.

It may also have a function of press molding on at least one side of the first base and the second base, the function of vacuum forming, and the function of stacking the cutting object into a three-dimensional molded body.

According to the present invention, since the three-dimensional cutting edge is formed by cutting, it is possible to secure the cutting of the part requiring precision.

Moreover, in this invention, not only the sheet | seat and the film-like flat object, but also the object which curved-formed the film or sheet | seat can be cut. In addition, according to the present invention, the edges (burrs, etc.) of the products formed by injection molding or press molding can be cut (removed) simultaneously with molding, and cracks in films having hard coat layers such as organic EL and solar cell protective films I can cut it without this
