Description

  The present invention relates to signboards, nameplates, nameplates, foundation plates, tie pins, cufflinks, seals and other metal sign plates, and in particular, three-dimensional display bodies such as letters and family crests on the surface side of the ground pattern body. The present invention relates to a label plate disposed and a method of manufacturing the label plate.

  As a conventional metal marker plate, a metal plate is laser processed to form a display part with through holes along outer contour shapes such as various characters, symbols, patterns, etc., and a fixed part on the back side of this display part. Some are composed of substrates that are spaced apart. Through a through-hole provided in the metal plate, the color of the substrate on the back side can be seen, and a three-dimensional and colored sign plate is provided (Patent Document 1). .

  However, the above-described marker plate is obtained by cutting out display portions of characters and the like from a metal plate, uses a thin metal plate, and other portions than the characters and the like remain unprocessed metal plates. That is, since the display portion is a through hole and is flush with the metal plate, the display portion itself has no stereoscopic effect. In addition, since the sign plate installed outdoors is often exposed to wind and rain or direct sunlight, it is required to withstand long-term use. Therefore, the conventional marker plate uses a stainless steel plate as a metal plate. Stainless steel plates do not rust, but are hard and difficult to work with, and post-processing finishes are also required. Furthermore, since laser processing equipment and post-processing finishing equipment are required to form through holes in stainless steel plates, the cost of a product will inevitably increase with a sign plate that has a strong personality by order production. There is a problem.

On the other hand, the conventional method of manufacturing a labeling plate using a mold is to create a prototype (wood mold) by carving wood, cast gypsum slurry, demold after curing, and then dry and create a plaster mold Then, the molten metal is cast, and after curing, the gypsum mold is broken to remove the mold. As another method for producing a cast marker plate, light is transmitted to a light transmitting portion provided in a mask material and irradiated to a liquid photocurable resin layer below the light transmitting portion, so that the pattern of the light transmitting portion is applied to the resin layer. There is a method of forming a resin prototype having a raised portion corresponding to the pattern of the translucent portion by forming and removing the resin layer at the uncured portion. According to this conventional method, it is possible to produce a resin prototype for a beautiful decorative casting in which a pattern is raised on the surface of the prototype easily and accurately regardless of the skill level of the operator (Patent Document 2). ).

Furthermore, as a method for casting a stamp made of titanium alloy, a stamp type (wooden) is made of wood, and a stamp-shaped vanishable model made of wax is produced using this stamp type. A refractory slurry is attached to form a refractory film, the internal disappearance model is removed by heating, and the precision casting mold in which the portion with the disappearing material becomes a casting space is formed. It is known that a titanium alloy seal is obtained by pouring molten titanium alloy and destroying a precision casting mold after solidification (Patent Document 3).

However, the method using a resin prototype or a wax disappearance model, like the method using a wooden mold as described above, requires the creation of a prototype for the mold. The manufacturing cost is increased depending on the material and working time. In addition, since the sign plate has a strong personality and high price as a custom-made product, it is preferable that the customer's request is fully reflected in the completed sign plate. It is quite difficult to interact with the customer while looking at the model and incorporate the customer's request into the original or vanishing model to make corrections.

  A first object of the present invention is to integrally form a metal display body such as a character having a certain thickness on the surface of a metal ground pattern body having a certain thickness in view of the above-described conventional drawbacks. Further, the pattern of the ground pattern body is formed by regularly providing through holes penetrating in the thickness direction, and the display body is sized to cover a plurality of through holes of the ground pattern body. Thus, since the display body is supported by the ground pattern body, the display body itself has a three-dimensional effect, the pattern of the ground pattern body also has a three-dimensional effect, and further, through the through holes of the ground pattern body. An object of the present invention is to provide a sign plate having a very original three-dimensional effect capable of taking in the pattern and color of an outer wall of a house or the like to which a sign plate is attached.

  The second object of the present invention is to create 3D data of a mold prototype on a computer screen without creating a mold prototype made of wood or resin, and for a mold created with 3D data on the computer screen. The prototype (appearance corresponding to the product labeling plate) is displayed on the screen, interacting with the customer while viewing the prototype for mold displayed on the screen, and changing the 3D data while incorporating the customer's request, and for the finished mold By subtracting the original 3D data from the 3D data that is the base material of the mold (usually a rectangular parallelepiped), 3D data of the mold having a casting cavity on the substrate surface is created, and this 3D data of the mold is output by a 3D printer. To create a mold made of gypsum (direct digital manufacturing, DDM). In other words, it is possible to manufacture a marker plate reflecting customer's request by casting a molten metal into a mold (actual mold) manufactured directly from 3D data without creating an actual mold prototype. It is to provide a way that can be done.

  In order to achieve the above object, the three-dimensional marker plate according to claim 1 includes a ground pattern body in which through holes penetrating through a metal plate material in the thickness direction are regularly arranged, and a surface of the ground pattern body. And a metal display body that protrudes integrally from the top and is disposed so as to cover the plurality of through holes.

  According to a second aspect of the present invention, in the marker plate according to the first aspect, the ground pattern has a curved surface shape such as a saddle shape, a saddle shape, and a corrugated shape.

  The invention of claim 3 is characterized in that in the marker plate of claim 1 or 2, a metal outer frame body provided so as to surround the outer periphery of the ground pattern body is provided.

According to a fourth aspect of the present invention, in the marker plate of the first, second, or third aspect, the cross-sectional shape of the through hole of the ground pattern body is the same as a Japanese pattern blank portion such as a Kanoko pattern, a hemp leaf pattern, a blue sea wave pattern, etc. It is also characterized by having a similar shape.

According to a fifth aspect of the present invention, in the marker plate according to the first, second, third, or fourth aspect, when the maximum length of the ground pattern body is 10 mm or more, the thickness of the ground pattern body is set to 1 mm above. In addition, the projection dimension of the display body is set to 1 mm or more to provide a three-dimensional effect as a whole. The three-dimensional effect can be maintained by changing the wall thickness of the ground pattern body and the protruding dimension of the display body depending on the use of the sign plate. For example, in the case of a foundation plate, the thickness and protrusion dimensions are about 7 mm or more since the width of the ground pattern body is about 450 mm, and in the case of a nameplate, the thickness and protrusion dimensions are about 5 mm or more because the width of the ground pattern body is about 220 mm. In the case of a cufflink, the thickness of the ground pattern body is 20 mm, so that the above thickness and the protruding dimension are 1.5 mm or more, and in the case of an approved seal, the diameter of the ground pattern body is 10 mm. Is 1 mm or more. That is, the stereoscopic effect can be maintained by setting the thickness and the protruding dimension to be one third or more of the square root of the width or diameter (maximum length) of the ground pattern body.

A sixth aspect of the present invention provides the marker plate according to the first, second, third, fourth or fifth aspect, wherein at least the ground pattern body and the display body are selected from the ground pattern body, the display body and the outer frame body. It is characterized by being integrally formed by casting a molten metal into the casting cavity.

According to a seventh aspect of the invention, in the method for producing a labeled plate according to the first, second, third, fourth, or sixth aspect, 3D data of the labeled plate is created on a computer, and the template plate is used based on the 3D data. 3D data is created, 3D data for the mold is output by a 3D printer to form a mold, and a molten metal is cast into the casting cavity of the mold, so that at least the ground pattern body and the display body are integrated. A method for forming a labeled plate of

As is clear from the above description, the following effects can be obtained in the present invention.
Since the marker plate according to claim 1 is provided with a display body such as a character having a certain thickness on the surface of the ground pattern body having a planar shape or a curved surface shape so as to cover the plurality of through holes. The display body can be supported by the ground pattern body and a stereoscopic effect can be imparted to the display body itself. In addition, since the sign plate has a ground pattern body in which the through holes are regularly arranged, the ground pattern body can be given a three-dimensional effect, and the color of the outer wall of a house or the like where the sign plate is installed. Since the pattern can be taken into the marker plate through the through-hole, a marker plate having a very original stereoscopic effect can be provided.

Moreover, since the through-hole of the ground pattern body becomes a meat stealing part and the amount of metal material used can be suppressed, the marker plate can be provided at a low cost. Further, since the display body has a size that covers the plurality of through holes, that is, a sufficient size as compared with the through holes, the display body is reliably supported by the ground pattern body.

In the sign plate according to claim 2, since the ground pattern body has a curved surface shape such as a saddle shape, a saddle shape, and a corrugated shape, it is possible to provide a sign plate having a more three-dimensional effect than the sign plate according to claim 1. it can. Since the branch part of the front-end | tip of a ground pattern body is continuously connected by an outer frame body, the label plate of Claim 3 is excellent in design property, and can provide the united label plate. Since the cross-sectional shape of the through hole is the same as or similar to the cross-sectional shape corresponding to the blank portion constituting the Japanese pattern, the sign plate of claim 4 is to provide a very Japanese-style and familiar sign plate. Can do. When the maximum length of the ground pattern body is 10 mm or more, the marker plate according to claim 5 has a thickness that can be visually recognized from the surface of the ground pattern body, with the thickness of the ground pattern body being 1 mm above, That is, since the display body having a thickness of 1 mm or more is provided, a stereoscopic effect can be imparted to the display body itself. The sign plate according to claim 6 is prepared by preparing a mold having a casting cavity corresponding to the ground pattern body and the display body, and casting a molten metal into the mold, so that the sign plate is heavy and durable. Can be obtained.

According to the invention of claim 7, the 3D data of the label plate prepared in advance is displayed on the screen of the computer, the 3D data is changed while checking the customer's request while watching this, and the label plate reflecting the customer's request 3D data is created, 3D data for a mold having a casting cavity is created using the 3D data of the marker plate, and a mold (actual mold) is created by outputting the 3D data for the mold with a 3D printer. Since the marker plate is formed by pouring molten metal into the casting cavity of this mold, the conventional wooden or resin prototype is unnecessary, and it is suitable for one-piece production by order and inexpensive. The manufacturing method of can be provided. In addition, since a mold is made using a 3D printer (layered modeling), generation of metal powder, sand-type waste sand and other waste due to cutting can be suppressed, and the material (eg, gypsum grains) remaining in the 3D printer can be reduced. Almost all can be collected, so there is almost no waste. It is possible to easily manufacture a mold whose inner shape is complicated and difficult to manufacture a mold, and which conventionally required a high processing cost, and to obtain an integrally formed product having excellent strength and quality.

  The metal material used for the marker plate of the present invention is preferably a metal that does not rust. For example, cast iron, bronze, brass and the like. As the ground pattern body of the sign plate, a planar shape is easy to manufacture, but a curved surface shape such as a saddle shape, a saddle shape, and a corrugated shape can exhibit a more stereoscopic effect. As a means for forming the through-hole of the ground pattern body, a metal plate material can be punched or laser processed, but it is preferable to cast a molten metal into a mold. The mold may be a three-dimensional casting cavity for forming a ground pattern having a curved surface. The mold can be manufactured (DDM) by outputting 3D data of the mold created by 3D modeling software using a 3D printer, and the material is preferably gypsum. If a plaster mold is used, it is preferable to use a copper alloy having a low melting temperature and capable of expressing various colors such as gold, silver and copper. The finishing method of the sign plate includes polishing such as buffing, hairline finishing, random finishing, surface treatment such as patina finishing, copper antique finishing, gold leaf finishing, paint finishing, white bronze, brass plating, hot-dip zinc plating, etc. Processing can be performed.

For the creation of 3D data (extension .stl) such as a label plate and a template, 3D CAD software such as 3D modeling software Solid Works, Space Claim, and AutoDisk can be used. In addition, free modeling software such as 123D design (extension .123d) and DS mechanical (extension .rsdoc) can be used. The casting cavity for the sign plate is obtained by subtracting the 3D data of the sign plate from the 3D data of the base material (usually a rectangular parallelepiped) as a mold (Subtract of the Combine command), so that the front side or the back side of the sign plate is placed on the base material surface. 3D data of a mold having a casting cavity with an open face can be created. Note that the terms addition and subtraction are sometimes called Boolean (set operation) depending on the software used.

Create data and save to file 2. FIG. 7B shows a graphic 32 in which 3D data of the outer frame of the file 2 is displayed on the screen.

Finally, the data of the characters “A” and “B” are called from the existing character data file, and the 3D data of the character is created by making the thickness 6 mm, and stored in the file 3. Note that the data of the characters “A” and “B” are grouped, and each element can be scaled, three-dimensionalized, and moved simultaneously. FIG. 7C shows the 3D data of the characters in the file 3 displayed on the screen.

The 3D data of the label plate is constructed using the 3D data stored in these three files 1, 2, and 3. That is, in order to create 3D data of the sign plate, the 3D data of the ground pattern body 6 in FIG. 7A is called, and the 3D data of the outer frame body in FIG. Is added and 3D data is added together. Then, by deleting the 3D data of the ground pattern body that protrudes from the outer frame body, 3D data of the ground pattern body surrounded by the outer frame body is generated.

The cross-sectional shape of the through-hole 74 is an equilateral triangle, and has the same or similar shape to the blank portion of the triple turtle shell pattern that is a traditional Japanese pattern. The outer peripheral portion of the ground pattern body 72 is surrounded by a circular outer frame body 75 having a thickness of 8 mm and a width of 12 mm. A 2 mm thick paulownia crest (display body) 76 is integrally provided on the surface of the ground pattern body, and is attached to the gate pillar or the door of the warehouse by screwing a screw rod onto the embedded nut on the back surface. The family crest can be displayed.

The marker plate of the third embodiment is reduced in scale, and a ground pattern body 72 is formed by crossing a bar with a thickness of 1 mm and a width of 1 mm at a distance of 5 mm and crossing at an inclination of 30 degrees and a reverse inclination of 30 degrees, and the outer periphery thereof has a diameter of 15 mm. A tie pin or a cuff button having a family crest 76 arranged as a display body surrounded by an outer frame body 75 of a size is produced. Projection height of the display body is 1.3mm, and it can be used as a tie pin if a clip is fixed to the embedded nut on the back side, and it can be used as a cuff button if a stopper is fixed to the embedded nut on the back side can do. When you want to make the crest of a cufflink symmetrical, use a 3D modeler's line symmetry (mirror) command to create 3D data with the crest directions reversed, and use a template output by a 3D printer as a pair of cuffs Make a button. In addition, if the ground pattern body is formed into a bowl shape, it is possible to obtain a cuff button having a very three-dimensional feeling. In any case, the color of the cutter shirt and the color of the sleeve can be seen from the through hole of the ground pattern body, and an original three-dimensional marker plate can be manufactured.

FIG. 11 is a perspective view showing a marker plate according to a fourth embodiment of the present invention. This embodiment relates to a stamp face member of a seal, and the stamp face member 90 is made of a titanium alloy and is used by being fixed to the lower surface of a short columnar holding member 91 made of marble. It is manufactured by the same method. The ground pattern 92 according to the marker plate of the present embodiment is obtained by crossing a bar 93 having a thickness of 1 mm and a width of 1 mm 3 mm apart with an inclination of 30 degrees and a reverse inclination of 30 degrees. 94 is formed. The outer peripheral portion of the ground pattern body 92 is surrounded by a circular outer frame body 95 having a diameter of 10 mm, a thickness of 2 mm, and a width of 1 mm. On the surface of the ground pattern body, a mirror image character 96 of the character “Kido” is integrally formed with a thickness of 1 mm and a width of 2 mm. Although not shown, a screw rod (not shown) protrudes from the back surface side of the marking member 90, and the screw rod is inserted into a mounting hole 97 formed in the end surface of the grip portion 91, and an inorganic adhesive or the like is inserted. You can fix it with a seal. If the gripping member 91 is made of a titanium alloy and is an integrally molded product without using the marble gripping member 91, screw rods and mounting holes are not required. In addition, if a small unevenness is provided by embossing on the surface (printed surface) of the mirror-image character 96 made of titanium alloy or the outer frame body 95, the adhesion of vermilion is improved. Furthermore, by making the ground pattern body and the display body into a bowl shape, it is possible to make a marking surface with a loose curved surface having an axis in the longitudinal direction, and it is possible to imprint while swinging around the axis. It can be a seal.
