First, the step of manufacturing the first mold 10 is a step for molding the second mold 20, and the first mold 10 is made of an impermeable material, more generally, like a conventionally well-known mold. consists of an upper mold 11 and a lower mold 13 made of an iron material, and a forming part 15 to match the shape of the second mold 20 molded by the upper mold 11 and the lower mold 13 ) is provided. (See [A] in FIGS. 1 and 2]

More strictly speaking, the molding part 15 is provided with a molding groove making protrusion 153 to form the molding groove 21 in the second mold 20 to match the shape of the coating layer HC, which will be described later. 2 It is made of a body manufacturing unit 151 for molding the body of the mold 20.

That is, the first mold 10 is made to have an embossed shape like the molding groove making protrusion 153 in order to form the molding groove 21 in the second mold 20 .

The method of manufacturing the second mold 20 is a method of hardening by putting a liquid molding agent in the same manner as in general molding to compress the upper mold 11 and the lower mold 13, or heat-compressing a solid material to form a molded product. That is, a method of molding the second mold 20 may be used, or a blow molding method may be used further, and the scope of rights should not be construed as being limited thereto.

However, in the present invention, since the second mold 20 must be molded with a light-transmitting silicone material, it is preferable to use a method of molding by injecting a silicone liquid to harden or by heating and compressing a silicone material rather than blow molding.

The second mold 20 manufactured by the first mold 10 is made of a light-transmitting silicone material, and the molding groove 21 is formed by the molding groove making protrusion 153 . As a result, it has an intaglio shape and has a light-transmitting property (Second mold 20 manufacturing step) ([B] in FIGS. 1 and 2)

However, if the substrate F is simply seated and then cured, a fine pressure difference may occur or air bubbles may be introduced to cause defective products.

The pressing step is a process for applying a constant pressure and leveling between the substrate (F) and the UV coating liquid (C) filled in the molding groove (21). By pressing the substrate (F) through a pressing roller, the UV coating liquid ( C) to improve the adhesion, and then proceed with the aforementioned curing process.

When the curing process proceeds as described above, the coating layer (HC) is formed on the substrate (F) in the same shape as in [D] of Fig. 2 and [B] of Fig. 3, and at this time, the coating layer (HC) is printed It is molded to have a different thickness depending on the shape of the emblem, so that the emblem can be expected to look three-dimensional.

That is, the molding groove 21 of the second mold 20 is formed in a non-flat shape according to the shape of the emblem to be manufactured, which is the molding groove of the first mold 10 for forming the molding groove 21 . It means that the end of the production protrusion 153 is made of a non-flat shape, which is implemented differently depending on the shape of the emblem, so that the shape is not limited.

In addition, when the coating layer (HC) is formed as described above, as a result, the coating layer (HC) surrounds the outer surface of the light emitting member (L), which is a structure that immediately secures the antifouling and waterproof properties of the light emitting member (L). It can also prevent damage to the emblem and increase productivity by shortening the manufacturing time compared to injection molding.

Furthermore, it is possible to minimize the flickering defect by preventing the light emitting member L from shaking by being cured while closely adhering to the outer surface of the light emitting member L, and the light emitting member L in the present invention is preferably made of an LED chip. This should not be construed as limiting the scope of rights.

In addition, it is self-evident that a separate power is applied to the rear surface of the substrate F to supply electricity to the light emitting member L.

As such, the substrate F on which the coating layer HC is formed is separated from the molding groove 21 of the second mold 20, and then enters the post-processing step,

It is also possible to apply a coating solution (C) to further form a separate coating layer on the outer surface of the molding groove (21) or the second mold (20) for smooth separation of the substrate (F), but the scope of rights is limited thereto should not be interpreted
