Hereinafter, with reference to the accompanying drawings will be described in detail for each embodiment of the present invention.

First embodiment

The braille block 1a for the blind according to the present invention has a shape similar to that of FIG. 2, which may be manufactured through the process of FIGS. 3 to 8. The manufacturing method will be described with reference to FIGS. 3 to 8 as follows.

First, the support plate material 10 of the metal material which has a predetermined unit size is provided. The braille block 1a shown in FIG. 2 is usually constructed by combining several pieces in the plate direction, but is manufactured as a unit size in manufacturing.

When the metal support plate 10 is prepared, as shown in FIG. 3, a plurality of cutouts 20 are formed on the plate surface of the support plate 10. Referring to FIG. 3, the support plate 10 has a total of twenty-five cut-out portions 20 in a horizontally and vertically uniform shape. The solid line in the cutout portion 20 indicates the cutout line with respect to the support plate 10 of the metal material.

As shown in FIG. 3, the cutout 20 is formed on the support plate 10, and then the cutout 20 is pressed on one surface of the support plate 10. Then, based on each cut line of the cutout part 20, it becomes a shape like FIG.

Referring to the enlarged “A” region of FIG. 4, as the pressing portion 20 is pressed, the plate surface of the support plate 10 is formed with a through hole 21, and is spaced upward from the through hole 21. The through piece 22 is located. In view of the shape of the cut-out portion 20, the through piece 22 is not separated from the remaining support plate 10 by the connecting portion 23.

The injection material passes through a space (not shown) between the through hole 21 and the connection portions 23 of the support plate 10 generated by separating the through pieces 22.

As shown in FIG. 4, after the supporting plate 10 is processed, the first and second molds 30 and 40 for injection are prepared. An upper protrusion molding part 31 is formed inside the first mold 30. The upper protrusion molded part 31 has the same shape as the upper protrusion part 51 which is frustoconical in FIG. 2 which is this braille block 1a. Similarly, a lower protrusion molded part 41 having the same shape as the lower protrusion part 52 having a disc shape in FIG. 2, which is the braille block 1a, is formed inside the second mold 40.

When the first and second molds 30 and 40 are prepared, as shown in FIG. 5, the supporting plate 10 of FIG. 4 is disposed between the first and second molds 30 and 40. At this time, as shown in Figure 6, in the support plate member 10 so that the through-piece 22 is in close contact with the upper surface 31a of the upper protrusion forming part 31 of the first mold (30).

After arranging the support plate 10 between the first and second molds 30 and 40, as shown in FIG. 7, injection into the second mold 40 through the injection material supply part 45 is performed. Inject the material 47. Of course, unlike shown, the injection material supply unit 45 may be formed in the first mold (30).

When the injection material 47 is introduced into the second mold 40, the injected injection material 47 passes through the hole 21 of the support plate 10 from the region of the lower protrusion molded part 41 of the second mold 40. Through) is filled into the upper protrusion molded part 31 of the first mold (30).

Of course, the filled injection material 47 is spread into the space between the connecting portion 23 of the support plate material 10 as well as the through-hole 21 formed in the plate surface of the support plate material 10. However, since the through piece 22 of the support plate 10 is in close contact with the upper surface 31a of the upper protrusion forming part 31 of the first mold 30, the injection material 47 does not spread in this region. .

When the filling of the injection material 47 is completed and the filled injection material 47 is solidified, the supporting plate 10 is removed from the first and second molds 30 and 40. Then, as shown in FIG. 8, the support plate 50 having the upper protrusion 51 of the truncated cone shape is formed on the upper side with the support plate material 10 therebetween, and the lower protrusion 52 is formed on the lower side of the support plate material 10. ), The braille block 1a can be obtained.

In this case, referring to the enlarged view of FIG. 8, it can be seen that the through pieces 22 of the same metal as the support plate material 10 are exposed on the upper surface of the upper protrusion part 51. It can be seen that the inside of the upper protrusion 51 is embedded. Since the through pieces 22 of the same metal as the support plate material 10 are exposed on the upper surface of the upper protrusion 51, even if the braille block 1a is used for a long time, the upper region of the upper protrusion 51 is worn. Resolved.

Of course, the upper and lower protrusions 51 and 52 are supported by the upper and lower protrusions 51 and 52 having the upper diameters of the upper and lower protrusions 52 formed by solidification of the injection material 47. There is no fear of separation from the plate 10.

As such, according to the first embodiment of the present invention, the upper region of the upper protrusion 51 may be prevented from being easily worn, thereby increasing durability and increasing productivity, thereby improving productivity.

Second embodiment

In the case of the first embodiment described above, molding is performed in a state in which the through pieces 22 are not separated from the support plate 10 by the connecting portion 23.

However, as shown in FIG. 9 showing the second embodiment, when the through-piece 22 is formed from the original support plate 10, both the through-piece 22 and the connecting portion 23 are separated from the support plate 10 It can also be manufactured in the state.

Even if the braille block is manufactured in this state, its appearance is the same as that of the braille block 1a of the first embodiment. That is, it can be seen that the through pieces 22 of the same metal material as the support plate material 10 are exposed on the upper surface of the upper protrusion part 51.

However, unlike the first embodiment, the connecting portion 23 is embedded into the upper protrusion 51, but is only embedded in a state separated from the support plate (10).

Third embodiment

The braille block 1b may be manufactured by applying the method of the third embodiment of FIGS. 10 to 13. For reference, overlapping description with the first embodiment is avoided, and the same reference numerals are used for the same configuration.

First, after providing the support plate material 10 to correspond to the process of FIGS. 3 and 4 of the first embodiment, a plurality of through holes 21 to allow the injection material 47 to pass through the plate surface of the support plate material 10. Penetrates.

As shown in FIG. 10, when a total of twenty-five through holes 21 are horizontally and evenly formed on the plate surface of the support plate 10, the through pieces 22 are generated in the process of forming the through holes 21. As described above, the through pieces 22 are in close contact with the upper surface 31a of the upper protrusion forming part 31 of the first mold 30.

However, even if the through-piece 22 having a relatively thin thickness is in close contact with the upper surface 31a of the upper protrusion forming part 31 of the first mold 30, even after molding by the method described above, after the completion of the molding, the support plate The through piece 22 may be exposed to the upper surface of the upper protrusion 51 of the 50. However, in this case, since the through piece 22 is thin, there is a possibility that the contact area with the injection material 47 is small, so that it is separated from the upper protrusion 51.

Accordingly, as shown in FIG. 11, the contact area with the injection material 47 is increased before the hole pieces 22 are brought into close contact with the upper surface 31a of the upper protrusion forming part 31 of the first mold 30. As a means for making a further reinforcement pillar 25 is formed in the through piece 22. Since the through piece 22 is made of a metal material, the reinforcement column 25 may be coupled to the through piece 22 by welding or other methods. At this time, the reinforcement column 25 is formed relatively small compared to the height of the upper protrusion (51).

Referring to FIG. 11 again, after the reinforcement column 25 is formed in the through piece 22, the through piece 22 is formed on the upper surface 31 a of the upper protrusion forming part 31 of the first mold 30. Make sure they are in close contact. Then, as shown in FIG. 12, the injection material 47 is injected into the second mold 40 through the injection material supply part 45.

When the injection material 47 is introduced into the second mold 40, the injected injection material 47 passes through the hole 21 of the support plate 10 from the region of the lower protrusion molded part 41 of the second mold 40. Through) is filled into the upper protrusion molded part 31 of the first mold (30). At this time, since the through piece 22 is in close contact with the upper surface 31a of the upper protrusion forming part 31 of the first mold 30, the injection material 47 does not flow into this area.

When the filling of the injection material 47 is completed and the filled injection material 47 is solidified, the supporting plate 10 is removed from the first and second molds 30 and 40. Then, as illustrated in FIG. 13, the support plate 50 having the upper protrusion 51 of the truncated cone shape is formed on the upper side and the lower protrusion 52 is formed on the lower side with the support plate material 10 therebetween. ), The braille block 1b can be obtained.

In this case, referring to the enlarged view of FIG. 13, it can be seen that the through pieces 22 of the same metal as the support plate 10 are exposed on the upper surface of the upper protrusion 51, and the reinforcement pillar 25 is provided. It can be seen that the silver is embedded inside the upper protrusion 51 and sticks to the injection material 47.

Since the through piece 22 of the same metal as the support plate 10 is exposed on the upper surface of the upper protrusion 51, even if the braille block 1b is used for a long time, the upper region of the upper protrusion 51 wears. Resolved. In addition, it is prevented that the through piece 22 is easily separated by the reinforcing column 25.

As described above, according to the third embodiment of the present invention, the upper region of the upper protrusion 51 is prevented from being easily worn, thereby increasing the durability and improving the productivity.

Although the present invention has been described in detail with reference to the drawings, the present invention is not limited thereto.

In the above-described first embodiment, the connecting portions 23 are described as being embedded inside the upper protrusion 51, but the connecting portions 23 are completely formed on the inner surface of the upper protrusion forming part 31 of the first mold 30. If it is in close contact after the molding is completed, the connecting portions 23 may be exposed to the surface of the upper projection (51).

In the above-described first embodiment, the cutout portion 20 is provided in the form of four connecting portions 23, but it is not necessarily the same as that shown.

In the second embodiment described above, the through piece 22 is obtained from the support plate 10, but the through piece 22 may be received from another place. That is, the through pieces formed in the support plate material 10 may be discarded and the through pieces 22 may be made from other metal materials.

Although the description is omitted in the above-described embodiments, a separate slip preventing means may be further interposed on the surface of the through piece 22 of the metal exposed to the upper surface of the upper protrusion 51.

The anti-slip means may be an uneven surface or a pad. Alternatively, before forming the through pieces 22, by pressing the support plate material 10 in the area where the through pieces 22 are located by using a press formed with the unevenness, the uneven surface for preventing slipping on the upper surface of the through pieces 22 is formed. It can also be formed. If the above manufacturing method is further provided and the manufacturing method is carried out as it is, the through-piece 22 having the anti-slip surface is formed on the surface of the product to be exposed to the outside, thereby exhibiting an anti-slip effect in addition to the anti-wear effect. .

In the above-described embodiments, the description thereof is omitted, but after forming the through pieces 22 from the support plate 10, before placing them on the first and second molds 30 and 40, insert injection, The support plate 10 may be coated including the through piece 22. Various types of coatings may be employed, such as ceramic coating. In this case, since the through-piece 22 exposed to the surface of the finally formed product is coated with a ceramic coating, it helps to secure durability. Of course, the coating also improves the beauty of the appearance.

As described above, according to the present invention, it is possible to prevent the top region of the upper protrusion from being easily worn, thereby increasing the durability and improving the productivity.
