Description

Thomson mold with improved leveling accuracy {THOMSON MOLD}

The present invention relates to a Thompson mold having improved horizontal adjustment accuracy, and more particularly, to a method of manufacturing a trimmable mold which is capable of precisely adjusting a horizontal position of a forming portion of a cutter while easily mounting a cutter on a base plate, A base plate having a fitting portion formed so as to penetrate both sides along the shape of the product so as to prevent the whole of the molding portions from being tilted; And a chamfer portion formed at one end or both ends of the other back surface portion, wherein the one-side forming portion is protruded from one surface of the base plate while the other back surface portion protrudes from the other surface of the base plate And a cutter fitted to the fitting portion of the base plate so as to be horizontally held with respect to the base plate so as to cut or fold or partially cut the sheet to be processed.

The Thomson mold refers to a material used for producing a product such as a polarizing plate or a packaging box by cutting, folding or partly cutting a sheet to be processed such as a thin plate-like synthetic resin or paper.

The Thompson mold can be used for cutting a sheet through a pressing process by mounting the cutter on a base plate along the shape of the product, for bending a folding line for folding the sheet, for forming a perforated line, The height of the forming portion of each cutter is mounted on the base plate so as to protrude at different heights so as to partially cut a part of the thickness.

That is, as shown in Fig. 3, the cutter for cutting is configured such that the whole of the forming part is made of a blade in the form of a straight line so that the product is cut in the sheet to be processed. A cutter for folding forming a thin folding line, a cutter for forming a partial cut, which is formed by a cutting line formed in a dashed line or at a different height so as to partially cut the target sheet in the longitudinal direction or in the thickness direction, Adjust the height of protrusion of each cutter so that it is cut or folded or partially cut to fit the application.

When a sheet is processed using these Thompson molds, the product is completed in the form of an exploded view on the sheet to be processed.

In this case, it is possible to prevent the defective molding of the product from occurring if the protruding height of each cutter is appropriately leveled for each use.

Therefore, in order to adjust and maintain the cutter horizontally, it is important to firmly maintain the fixed state of the cutter inserted in the base plate. However, if each cutter is separately manufactured and fitted to the base plate as shown in FIG. 3,

In the case where the side end portions of the cutters meet, that is, in the region where the side end portions of the cutters intersect, it is difficult to mount and level the cutter because the side end portions of the cutters are in close contact or contact with each other. There is a case in which the horizontal level of the cutter is changed together, and it is difficult to precisely control the cutter again.

In particular, in the case of the Thompson mold for sample production, not the Thompson mold for mass production, a simple wooden mold in which the structure of the mold is simplified is mainly used. Since the cutter is fixed in such a manner that the cutter is constrained to the fitting portion of the base plate, And the horizontal position of the cutter is easily changed.

That is, in the conventional Thomson mold such as Patent No. 10-0653614, in order to fix most of the cutter (blade), apart from the groove-like fitting portion of the shape corresponding to the outer shape of the product, And the side surface of the cutter is pressed and fixed by sandwiching the fixing block in the auxiliary fitting portion in a state where the cutter is sandwiched between the fitting portions,

Such a conventional technique is expensive to manufacture because it is manufactured using a metal mold and a block,

It is mainly suitable for the structure of the Thompson mold for mass production,

In the case of the Thompson mold for sample production in which the product design and the like can be frequently changed, the above-described conventional technology is applied, and the expensive manufacturing cost of the mold increases every time the product design is changed, It takes a long time to manufacture, which is an inefficient method.

In addition, in order to prevent breakage or damage of the molded portion (blade) of the cutter when the conventional Thompson mold does not have the above-described joint structure of the fixed block, a fitting portion is formed through both sides of the base plate, The cutter must be mounted so that the forming part is protruded to one surface of the base plate by pushing the part from the other surface of the base plate to the fitting part,

A separate fixing member capable of fixing the other back surface portion of the cutter fitted in the fitting portion of the base plate is difficult to attach or attach to the other surface of the base plate due to the operational structure of the Thomson mold, ,

If the operator horizontally adjusts the cutter horizontally, the operator may interfere with one another due to contact or contact of one end of the cutter, and the horizontal of the other cutter, which does not need to be horizontally adjusted, may be distorted.

That is, if all or a part of the cutter for cutting is pushed toward the base plate, the height of the protrusion of the blade becomes shallow so that the sheet is not cut, or if all or part of the cutter for folding is excessively protruded from the base plate, Or if the entire or part of the cutter for partial cutting is pushed toward the base plate or excessively protruded from the base plate, partial cutting is not performed for a desired length, It is very important to precisely adjust and maintain the horizontal position of the forming part of each cutter. However,

The conventional Thompson mold is not only difficult to add a separate fixing member for horizontal adjustment of the individual cutter since the side end portions of the cutters are disposed adjacent to each other with one fitting portion connected to each other,

In order to solve this problem, when the fixing member of the present invention is added to the region where the side ends of the cutters are disposed adjacent to each other, the additional fixing member supports the cutter which does not need leveling, So that the horizontal state of the cutters is totally distorted, thereby causing defective molding.

In other words, as shown in Figs. 3 and 4, when the side ends of the different kinds of the cutters are mounted adjacent to each other in an intersecting manner, when the fixing member of the present invention is attached, It tends to support the end portion while penetrating into the region,

Therefore, even the folding cutter that does not cut the sheet is excessively projected beyond the set height on the base plate by being pressed by the fixing member, so that the crossing area where the cutting line, the folding line, There is a problem that a defective process such as breaking or bursting or tearing easily due to a thin thickness is likely to occur.

In order to prevent such a problem, there are public utility models 20-2011-0008884, registered utility models 20-0260510, and 10-1315027, etc. These patents and utility models are also disclosed in the above- In addition, it is necessary to add additional insertion grooves or fixing blocks for fixing the cutter (blade), which complicates the mold structure and increases manufacturing cost.

Accordingly, the present invention has been made to solve the above-mentioned problems,

The simplified structure design makes it easy to install the cutter on the base plate, making it easy and quick to produce Thompson molds, low cost of installation, precise adjustment of the horizontal position of the forming part of the cutter, and interference with other cutters A base plate having a fitting portion formed so as to penetrate both sides along the shape of the product so as to prevent the whole of the molding portions from being tilted; And a chamfer portion formed at one end or both ends of the other back surface portion, wherein the one-side forming portion is protruded from one surface of the base plate while the other back surface portion protrudes from the other surface of the base plate And a cutter mounted on the fitting portion of the base plate so as to be held horizontally with respect to the base plate so as to cut or fold or partially cut the sheet to be processed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a Thomson mold having improved horizontal adjustment accuracy according to the present invention will be described with reference to the accompanying drawings.

1 which is a cross-sectional view schematically showing the coupling relationship between the base plate 10 according to the present invention and the cutter 20 and the fixing member 30, FIGS. 2 and 3 which are front views according to embodiments of the cutter 20 according to the present invention, Fig. 3 is a photograph of a bottom surface of a sample according to the present invention taken in a plane, and Fig. 3 is a photograph obtained by a partial enlargement photographing. Fig. 3 is a photograph of a top surface of a sample according to the present invention, As noted,

The Thompson mold according to the present invention comprises a base plate 10 provided on a press part of a press device and mounted on a press part of the mold part, And a fixing member 30 attached to the other surface of the base plate 10 to support the cutter 20.

The base plate 10 is made of wood such as plywood, and the fitting portion 11 is formed to penetrate both sides of the base plate 10 along the product shape.

The fitting portion 11 is a groove-like structure in which the cutter 20 is forcedly inserted, is formed by laser or scissoring,

At this time, the width of the fitting portion 11 is formed to be finer than the thickness of the cutter 20.

In the drawing, a shape of a fitting portion 11 for forming a sheet to be processed (not shown) to be folded and attached to a packing box or the like is shown.

A cutter 20 in the form of a strip is fitted in the fitting portion 11 with interference.

The cutter 20 is formed in a strip shape and has one side forming portion 21, another side back portion 22 and a chamfer portion 23 formed at one end or both end portions of the other side back portion 22, The forming portion 21 is protruded from one surface of the base plate 10 and the other back surface portion 22 is formed on the fitting portion 11 of the base plate 10 so as to be parallel to the other surface of the base plate 10. [ And the sheet to be processed is cut, folded or partly cut.

Such a cutter 20, as shown in a partially enlarged photograph of Fig. 3,

A cutter for cutting 20A made up of a cutting edge 21A for cutting and separating a sheet from the one-side forming portion 21,

A folding cutter 20B having a folding blade 21B for folding and forming the sheet on one side of the sheet 21,

Among the cutters 20C for cutting a part of a part, which is made up of a cutting edge 21C for cutting and separating a part of the sheet for forming a perforated line or the like on the sheet,

It is composed of any one or a combination of two or more.

The cut forming cutter 20A has a one side forming portion 21 formed as a cutting blade 21A in the longitudinal direction so that when the base plate 10 is pressed and pressed, Is completely cut and separated.

The folding cutter 20B is formed by a blunt bending blade 21B extending in the lengthwise direction so that the bending blade 21B is contacted when the base plate 10 is pressed So that the folding line is formed so that the product can be folded.

The cutter 20C for partial cut molding has a part cutting edge 21C projecting at a different height from the cutting cutter 20A in the form of a dotted line in the longitudinal direction A part of the lengthwise direction or a part of the thickness direction thereof is partially cut to cut and remove a part of the product when the base plate 10 is pressed and operated, .

In the figure, a cutter for partial cut molding 20C having a one-side forming portion 21 made up of a partial cutter blade 21C for partially cutting a sheet in a dotted line form can be identified.

When the cutters 20 are assembled according to the product design structure and the cutters 20 are mounted on the fitting portion 11, the to-be-processed sheet cut by the Thompson mold is formed into a developed shape corresponding to the shape of the product And then discharged.

Particularly, the present invention is characterized in that the chamfered portion 23 formed by removing a part of the cutter 20 is formed at one end or both ends of the other backside portion 22 so that the cutter 20 and the base plate 10 contact each other The cutter 20 is inserted into the fitting portion 11 so that the cutter 20 can be easily fitted to the other surface of the base plate 10 so that the cutter 20 can be easily fitted to the other surface of the base plate 10, The contact pressure on the upper end of the back surface portion 22 of the cutter 20 caused by the frictional force can be relieved so that the portion where the deformation is likely to be relatively bended or deformed can be prevented.

It is also possible to manufacture the cutter 20 with different vertical lengths between the one molding part 21 and the other back part 22 in accordance with the molding design of the product so that the other back parts 22 of the cutters 20 When fitted horizontally on the other surface of the base plate 10,

Not only a separate adjustment work for adjusting the level of the cutter 20 is required but also the upper and lower lengths of the cutter 20 are precisely machined so that the workpiece sheet is pressed and formed so that the horizontal adjustment precision of the Thomson die Can be improved.

It is more preferable that the chamfered portion 23 is provided at one end or both ends of the cutter 20 for folding.

More specifically,

The present invention can be applied to a case in which the base plate 10 is fixed to the other surface of the base plate 10 while covering the other back surface portion 22 of the cutter 20 as shown in [B] and [B] Member (30).

The fixing member 30 has a thin fixing tape as shown in Fig. 4 so as not to interfere with the operating structure of the press apparatus.

The present invention is advantageous in that the cutter 20 is pushed to the other surface side of the base plate 10 from the fitting portion 11 by the repeated pressing pressure so that the one formed portion 21 of the cutter 20 is likely to be lower than the original projecting height Therefore,

The fixing tape 30 is cut so as to fit the length of the other back surface portion 22 of the cutter 20 and attached so as to cover the other back surface portion 22. By this operation of the press device, 20 of the fixing member 30 by the thickness of the fixing member 30,

It is possible to prevent the horizontal state of the cutter 20 from being changed in advance or to horizontally adjust the cutter 20 whose horizontal position has been changed to the original height of the protrusion so that the cutter 20 can be reused.

In particular, the fixing member 30 made of a fixed tape having a small thickness can adjust the horizontal height of the one-side forming portion 21 by supporting the cutter at an appropriate pressure without significantly affecting the mold structure or operation of the pressing apparatus .

As described above, in the present invention, the cutter 20 is supported by the fitting portion 11 through the attachment of the fixing member 30, and the cutter 20A for cutting a sheet to be processed, In the case of the cutter 20C for cutting, it is preferable that the cutting pressure is maintained by supporting one end or both ends of the other back surface portion 22 by the fixing member 30,

In the case of the folding cutter 20B for pressing the sheet to be processed, if one end or both ends of the other back surface portion 22 are supported by the fixing member 30 due to the processing characteristic, 20B are formed so as to have a high protruding height at one side so that the thickness of the end portion of the folding line becomes excessively thin to excessively press the portion to be squeezed so that it is blown by the pressing pressure or is easily broken after crimping It is more preferable that the chamfered portion 23 be formed at both ends of one end portion of the other back surface portion 22 of the fold forming cutter 20B.

4, in order to attach the fixing member 30 and to support the cutter 20, the fixing member 30 has to have a predetermined width,

As shown in [B] of FIG. 4, when the fixing member 30 is attached to an area where one end of each cutter 20 intersects with each other according to the product shape, the end of the fixing member 30 needs to be supported The cutter 20, that is, the one end region of the folding cutter 20B, is likely to break and break due to the excessive pressing.

Of course, it is possible to prevent the above-described problems by cutting the fixing tape so as to exactly match the length of the other backside portion 22 of the cutter 20 and attaching the fixing member 30,

The fixing member 30 can not be cut and used in the correct length of the fixing tape 30 because the position and direction of the fixing member 30 are likely to be changed during attachment of the fixing member 30, ), And thus,

Therefore, when the beveled portion 23 is formed at one end or both ends of the other backside portion 22 formed on the folding cutter 20B, the fixation member 30 is fixed to the chamfered portion 23 as shown in [B] The fixing member 30 and the chamfered portion 23 are not in contact with each other so that the folding cutter 20B can be prevented from being unnecessarily pressed and supported as described above.

The chamfered portion 23 is formed on the other backside portion 22 of the cutters 20A and 20C other than the fold forming cutter 20B in accordance with the number, Things are also possible.

On the other hand, as shown in Fig. 2, the chamfered portion 23 of the present invention,

Among the rectangular-shaped chamfered portion 23a, the serrated chamfered portion 23b, and the rounded chamfered portion 23c,

It is composed of any one or a combination of two.

The selection or combination of the chamfered portions 23 may vary depending on the thickness of the cutter 20, the use, the number, shape, spacing, etc. of the cutters 20,

The rectangular-shaped chamfer 23a is suitable for the cutter 20 having a relatively small pressure acting on one end of the corresponding one-side forming portion 21 and advantageous in securing a maximum non-contact area,

The quadrangular chamfer portion 23b is suitable for the cutter 20 having a relatively large pressure acting on one end portion of the one-side forming portion 21 corresponding thereto and securing a minimum noncontact area,

The round chamfer 23c is suitable for the cutter 20 which is advantageous in that a pressure is relatively applied to one end of the one-side forming portion 21 corresponding to the one end, and that the noncontact area is secured to a medium size.

In the figure, the round chamfered portion 23c is rounded to the inside of the cutter 20, but the rounded chamfer 23c may be rounded to the opposite side (convex shape outward of the cutter 20) Do.

The chamfered portion 23 is formed to have a linear section length d1 (see [A] in FIG. 1) on the same horizontal straight line as the other rear portion 22 of 1 to 10 mm.

The linear section length d1 of the chamfered portion 23 may vary depending on the use of the cutter 20 and the length or thickness of the cutter 20. However, if the linear section length d1 is too short, The linear section length d1 of the chamfered portion 23 is within the range of 1 to 10 mm because the clamping force of the cutter 20 may be weakened if the straight section length d1 is too long, Is more preferable.

The chamfered portion 23 also has a linear section length d2 (see [A] in Fig. 1) located on the same vertical line as the one end or both ends of the cutter 20, .

The linear section length d2 is formed such that the linear section lengths d1 and d2 are symmetrically formed within the same range while the linear section length d1 is relatively less affected by the formed length than the linear section length d1, So that the deterioration of the rigidity of the cutter 20 which is weakened by the cutter 23 is minimized.

While the present invention has been described with reference to the accompanying drawings, it is to be understood that the invention is not limited to the above embodiments and various changes and modifications may be made therein without departing from the spirit and scope of the invention. Changes and substitutions are to be construed as falling within the scope of protection of the present invention.
