본 발명은 표면에 자개가 접착된 칠기 공예품의 백골 제조방법에 관한 것으로 백골을 사출에 의해 성형하되 표면에 자개가 심착된 상태로 단일공정에서 성형함을 특징으로 하며 특히 자개 표면을 평면으로 펴지 않은 상태, 즉 재단만되어 있는 상태의 굴곡되어 있는 자개편이 사출성형시 평면으로 펴지면서 백골 표면에 심착됨을 특징으로 한 방법이다. 종래에도 합성수지로 백골을 압형하였으나 그 방법은 일차가압의해 백골을 압형한 다음 완전경화되기 전의 백골표면에 자가 무늬포를 적충한다음 재차 가압에 의해 자개가 백골표면에 심착되도록 하는 방법이 있었다.The present invention relates to a method for producing a white bone of lacquer crafts with mother-of-pearl glued to the surface, characterized in that the white bone is molded by injection, but the mother-of-pearl is molded in a single process with the mother-of-pearl attached to the surface. It is a method characterized in that the bent mother-of-pearl piece in the state, namely, the state of being cut, is deposited on the surface of the sciatic bone as it is extended to the plane during injection molding. Conventionally, the sciatic bone was pressed with synthetic resin, but the method was to press the sciatic bone by primary pressure, and then apply a self-pattern to the sciatic surface before completely hardening, and then press the mother-of-pearl on the sciatic surface again by pressing.

이때 자개는 재단후 평면상태로 펼친다음 자개무늬포에 접착하기 때문에 종래의 압형 방법은 자개를 평면으로 펴는 작업공정과 접착공정, 2회의 가압공정을 거쳐 성형하였다.At this time, the mother-of-pearl is unfolded in a planar state after cutting and then bonded to the mother-of-pearl pattern fabric.

본 발명에서는 종래의 많은 공정을 단순화하며, 특히 자개를 평면으로 펴는 작업이 없이 사출성형시 그 사출압과 열에 의해 자동으로 펴지면서 백골표면에 심착되도록 한 것이다. 즉 원패를 임의 모양으로 재단한 자개편을 자개무늬포에 모양을 이루도록 접착한 자개무늬포를 사출금형내에 일치시킨 다음 사출시 사출압과 열이 자개의 요입면에 작용하여 압의 이동에 따라 평면으로 펼쳐지면서 표면에 심착된 상태의 백골이 성형되는 것이다. 이를 첨부된 도면에 의하여 본 발명실시를 상세히 설명하면 다음과 같다. 가동 및 고정금형 (1)(2)을 이용하여 합성수지제 백골 (6)을 사출 성형함에 있어서 고정금형 (2) 내에 자개무늬 (4)를 안치시킨다, 이때 자개편 (3)은 원패에서 재단된 것을 평면으로 펴지 않고 직접 무늬지에 등부분 (3b)을 접착하여 임의 무늬모양을 갖춘 자개 무늬지 (4)로 형성하며 자개편 (3)의 요일부 (3a)가 가동금형 (1)을 향하도록 안치시킨다.The present invention simplifies many conventional processes, and in particular, is to be deposited on the surface of the white bone while automatically unfolding by the injection pressure and heat during injection molding without the operation of flattening the mother-of-pearl. In other words, the mother-of-pearl cut in a random shape is matched to the mother-in-law fabric to match the mother-of-pearl pattern in the injection mold. Unfolded into the white bone of the state that is attached to the surface is to be molded. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. In injection molding the synthetic sciatic bone 6 using the movable and stationary molds (1) and (2), the mother-of-pearl pattern (4) is placed in the stationary mold (2), wherein the mother-of-pearl (3) is cut from the original plaque. The back portion (3b) directly to the patterned paper without forming the flat surface to form a mother-of-pearl patterned paper (4) having an arbitrary pattern shape so that the day portion (3a) of the mother-of-pearl (3) faces the movable mold (1). Place it.

안치후 가동금형 (1)을 닿은 후 사출을 하면 압과열이 있는 사출액이 고정금형 (2)의 바닥쪽 즉 자개무늬지 (4)로부터 사방으로 퍼져 금형의 접합면 (5)쪽으로 이동하면서 금형내에 충만되므로 백골 (6)이 형성되는데 사출이 열을 갖은 압은 자개편 (3)의 요입부 (3a)에서 사방으로 퍼지게 되므로 자개편 (3)은 열에의해 연질화되면서 압에 밀려 평면으로 퍼지게 된다. 이때 사출압은 800-1500kg/㎤, 온도는 100-250℃이다.When the injection is made after the movable mold (1) is settled, the injection liquid with pressure overheat spreads from the bottom of the fixed mold (2), that is, the mother-of-pearl pattern (4), and moves toward the joint surface (5) of the mold. As it is filled in, the white bone 6 is formed, and the pressure with the injection is spread in all directions from the recess 3a of the mother piece 3, so that the mother piece 3 is softened by heat and pushed by the pressure to spread to the plane. do. At this time, the injection pressure is 800-1500kg / cm 3, the temperature is 100-250 ℃.

이와 같이 성형된 백골 (6)은 표면의 자개무늬지 (4)를 연마하여 자개편 (3)을 현출시키며 연마후에는 표면에 투명도금을 도포하여 자개편 (3)외 주연과 백골 (6)의 경화시 수축되면서 자개편 (3)과 벌어진 미세한 틈을 메꾸어 완제품을 얻는다.The white bone 6 formed as described above polishes the mother-of-pearl pattern 4 on the surface to reveal the mother-of-pearl piece 3, and after polishing, the surface of the mother-of-pearl (3) and the periphery and the skeleton (6) During hardening, it shrinks and fills the mother-of-pearl (3) and the gaps between them to obtain a finished product.

이와 같은 백골의 제조방법은 자개를 펴주는 작업이 필요없이 직접 사출에 의해 자개가 심착된 상태로 백골이 성형되므로 생산작업이 매우 신속하고 량산할 수 있는 효과가 있다.Such a method of manufacturing a white bone has the effect that the production work is very quick and mass production because the white bone is molded in a state where the mother-of-pearl is deeply deposited by direct injection without the need for straightening the mother-of-pearl.
