And a waterproof molding type stereoscopic signboard which can project light through the light transmission molding by inserting the light transmission molding into the diffusion hole drilled in various shapes in the molding frame of the stereoscopic signboard, And a method for producing the same.

In general, signboards are used to install their own business sites for the purpose of advertising to other people.

The signboards used for the above purpose are divided into a two-dimensional stereoscopic signboard.

Meanwhile, such a stereoscopic signboard is required to have a distinctive identification or visibility so that the consumer can easily recognize the contents thereof, and it is indispensably provided with an illuminating device which can be seen well at night as well as during the day.

The conventional stereoscopic signboard is composed of a molding frame molded in a letter or pattern in a cylindrical shape having upper and lower openings, an upper panel mounted on the upper part of the molding frame, an upper cover for airtightness of the upper panel and the molding frame, Base module.

The forming frame is formed with an engaging portion for fixing the upper panel and the base panel. The engaging portion is integrally bent in the forming frame, or formed by injection or extrusion.

In addition, in the case of the above-mentioned bonding method, the molding frame made of a metal and the upper panel made of a synthetic resin are different from each other in physical properties, resulting in poor adhesiveness, thereby deteriorating product reliability.

In addition, all of the above-described methods are repeatedly exposed at a high temperature and a low temperature due to the characteristics of a stereolithography board installed on the outside, and the thermal expansion coefficients of the interlocking metal fixing part and the upper panel of the synthetic resin are different, There is a problem that separation (separation) occurs.

This has a problem in that the durability of the stereoscopic signboard itself is lowered, as well as water or foreign matter flows into the space between the separated spaces to cause a malfunction or a safety accident of the illuminating unit.

In addition, since the stereoscopic signboard is formed of a metal material integrally formed with the forming frame, the light irradiated from the lower illuminating portion is covered by the engaging portion, thereby causing a light blind phenomenon in which the corner of the stereoscopic signboard is black .

FIG. And FIG. 6 is a cross-sectional view showing only the upper panel in the waterproof molding type stereoscopic signboard of the present invention.

The stereolithography board 1 of the present invention is formed such that the engaging portion 5 is formed at the upper portion and the assembling rail groove 6 is formed at the lower portion in the longitudinal direction in the process of molding into a three- And molding the forming frame 12. (S1)

Therefore, the forming frame 12 has a structure in which the upper and lower portions are open. In the upper portion, a latching portion 5 is formed facing the right and left ends, and assembly rail grooves 6 are formed facing the lower and left ends.

The lower part of the assembly rail groove 6 is formed as a round shape 13 along the longitudinal direction so that the insertion of the base panel 3 is facilitated.

An upper panel 2 made of an upper acrylic or light diffusing polycarbonate is inserted into the engaging portion 5 of the forming frame 12 to be seated.

The upper panel 2 is formed with an upper engaging groove 15 having a rectangular shape or an inverted triangular shape inward from the upper surface.

Therefore, when the molding liquid is injected to form the upper molding 10 on the upper surface of the upper panel 2, a part of the molding liquid is inserted into the upper engaging groove 15 to be molded so that the upper molding 10 is fixed do.

The upper panel 2 allows the light source irradiated from the LED light source panel 4 to be uniformly diffused over the entire upper portion of the molding frame 12.

The upper surface of the upper panel 2 and the inside of the molding frame 12 are coated with an epoxy resin or urethane or a liquid such as urethane or polyurethane so as to prevent rainwater and moisture from penetrating into the molding frame 12, The upper mold 10 is sealed with a liquid. (S3)

The LED light source panel applied to the present invention is a light emitting diode (LED) ) Are sealed with an individual constitution by a material such as silicon, and they are connected again by wiring to prevent the inflow of rainwater or the like.

The base panel 3 is fitted into the assembly rail groove 6 of the molding frame 12 at step S6 and the base panel 3 is inserted into the molding frame 12 and then bonded or siliconized (S7)

4 is a cross-sectional view showing another embodiment of a method of manufacturing a waterproof molding type stereoscopic signboard according to the present invention, and Fig. 5 is a perspective view showing Fig.

The stereolithographic board of the present invention allows the light source emitting light from the LED module to be diffused through both sides of the molding frame.

Therefore, the molding frame 12 can spread the light source transmitted through the diffusion holes 8 formed on the both sides of the molding frame 12 in various shapes along the longitudinal direction to the sides of the molding frame 12, thereby maximizing the advertising effect.

In the method of manufacturing the stereoscopic sign 1, in the process of molding into the shape of a three-dimensional character or a three-dimensional shape, the molding frame 12 is formed with a plurality of circular or square or star- The molding frame 12 is processed so as to form the diffusion holes 8 and the tape 9 is adhered to the diffusion holes 8 formed on both sides of the molding frame 12 and sealed.

In addition, an epoxy-based, resin-based or urethane-based raw material is injected into the diffusion hole 8 of the molding frame 12 and then dried to form the light transmission molding 11.

In the operation of the translucent molding 11, various colors can be mixed to transmit light of various colors to the outside.

The shaping frame 12 is formed into a three-dimensional shape after the tape 9 is removed from the diffusion hole 8 of the shaping frame 12 and the assembling rail groove 6 is formed in the upper portion thereof and the assembly rail groove 6 in the longitudinal direction And an upper panel 2 made of acrylic or light diffusing polycarbonate is seated on the latching part 5 located at the upper part of the latching part 5 of the forming frame 12.

Epoxy resin or urethane is top-molded (10) by a liquid-type liquid on the upper surface of the upper panel (2) and the molding frame (12).

The base panel 3 is processed into round shapes 13 and 13 'in the longitudinal direction at both upper and left ends so as to be easily inserted into the assembly rail grooves 6 of the molding frame 12, The panel 4 is completed.

The LED light source panels 4 are arranged and attached to the base panel 3 at regular intervals.

The upper molding 10 of the forming frame 12 is turned upside down and then the base panel 3 positioned at the lower position is coupled to the base panel 3 inserted into the assembling rail groove 6 of the forming frame 12. Then, 3) is closed by bonding or silicone or by means of a clip (14).

Accordingly, the light source emitting light from the LED light source panel 4 passes through the light transmission molding 11, a part thereof is transmitted through the diffusion hole 8 and diffused, and the remaining part is transmitted through the upper panel 2 and the upper molding 10 The spread can maximize the advertising effect.

Therefore, when the three-dimensional base plate 1 is manufactured, diffusion holes are formed in the molding frame 12 in various shapes to transmit light to the diffusion holes 8 of the molding frame 12 as well as the upper panel 2.
