The heating plate 25, which is moved forward and backward, is installed. In the drawing, reference numeral 6 is an auxiliary sealing plate and 27 is a hot press plate.

이러한 구성으로 된 본 발명의 장치에 의해 장식판(A)을 제조하는 방법을 설명하면 다음과 같다.Referring to the method of manufacturing the decorative plate (A) by the apparatus of the present invention having such a configuration as follows.

금형판(4)의 보강테(6)와 받침판(7) 및 밑판(9)의 접합된 틈새를 테이프(15)로 제 2 도와 같이 밀폐시킨후 금형판(4)의 표면에 염화비닐 필름지(1)나 열전사 필름지(la)를 테이프(16)로 밀폐되게 부착한다.The sealing gap between the reinforcing frame 6 of the mold plate 4, the support plate 7, and the bottom plate 9 is sealed with a tape 15 as a second tape, and then a vinyl chloride film sheet is formed on the surface of the mold plate 4 ( 1) or the thermal transfer film (la) is hermetically attached with a tape (16).

이때 염화비닐 필름지(1)는 비닐지(14)가 위로 놓여야 하며 열전사 필름지(la)는 투명 필름지(lla)가 위로 놓이게하여야 된다.In this case, the vinyl chloride film 1 should be placed on the vinyl paper 14, and the thermal transfer film la should be placed on the transparent film paper lla.

그후 상기와 같이 금형판(4)에 부착된 염화비닐 필름지(1)나 열전사 필름지(1a) 표면에 제 7(b) 도와 같이 접착제(2)를 분사 도포한후 금형판(4)을 진공판(20)에 공기흡입공(22)의 천공된 진공흡착기 위에 올려놓는다.Thereafter, after spraying and applying the adhesive 2 to the surface of the vinyl chloride film 1 or the thermal transfer film 1a attached to the mold plate 4 as described above, the mold plate 4 is vacuumed. The plate 20 is placed on the perforated vacuum adsorber of the air suction hole 22.

이때 금형판(4)의 밑판(9)에 형성된 공기통로(10)가 진공판(20)의 공기흡입공(22)과 일치되게 놓아야 하며 금형판(4)으로 덮히지 않는 부위의 공기흡입공(22)은 보조밀폐판(26)으로 밀폐시킨다.At this time, the air passage 10 formed on the bottom plate 9 of the mold plate 4 should be placed in accordance with the air suction hole 22 of the vacuum plate 20 and the air suction hole of the portion not covered by the mold plate 4. (22) is sealed with a secondary sealing plate (26).

이러한 상태에서 모터(23)를 구동시켜 히팅판(25)을 제 8(b) 도와 같이 금형잔(4) 직상부에 놓이게 이동시키고 적당한 열을 가하면 염화비닐 필름지(1)나 열전사 필름지(la)는 얼음받아 늘어지면서 몰드(5)의 성형홈으로 내려가게 되며, 이때 진공관(21)과 접속된 진공판(20)에서 공기흡입공(22)을 통해 공기를 강하게 빨아 들이면 염화비닐 필름지(1)나 열전사 필름지(la)와 몰드(5)사이에 있던 공기가 공기구멍(8)을 통해 신속하게 빨려 나가면서 열을받아 축 늘어지는 염화비닐 필름지(1)나 열전사 필름지(1a)는 제 8(b) 도와같이 매우 효과적으로 몰드(5)의 입체감있게 형성된 형을 따라 밀착이 된다.In this state, the motor 23 is driven to move the heating plate 25 to the upper portion of the mold cup 4 as shown in the eighth (b). When the proper heat is applied, the vinyl chloride film 1 or the thermal transfer film la ) Is lowered to the forming groove of the mold 5 while receiving ice, and when the air is strongly sucked through the air suction hole 22 in the vacuum plate 20 connected to the vacuum tube 21, the vinyl chloride film 1 ) Or the vinyl chloride film 1 or the thermal transfer film 1a, which is drooped by heat while the air between the thermal transfer film la and the mold 5 is sucked out through the air hole 8, As in the case of the eighth (b) tile, it is in close contact with the mold having the three-dimensional shape of the mold 5 very effectively.

그후 상기와 같이 표면에 접착제(2)가 도포된 상태에서 몰드(5)에 흡착되어 있는 염화비닐 필름지(1)나 열전사 필름지(la)위에 우레탄액을 채워넣고 그 표면에 이형지를 놓온후 제 9 도와 같이 통상의 열프레스판(27)으로 눌러 압착하면 우레탄액이 몰드(5)의 형태를 따라 발포 경화되면서 접착제(2)에 의해 염화비닐 필름지(1)나 열전사 필름지(1a)와 양호하게 융착이 되며, 그후 금형판(4)으로부터 테이프를 떼어내어 몰드(5)로부터 분리시키면 표면에 나무 무늬결이 자연스럽게 포출되는 본 발명의 장식간을 얻을 수가 있는 것이며, 열전사 필름지(la)의 경우 투명필름지(1la)를 제 6(b) 도와 같이 벗겨내면 저면의 도안층(12a)이 그대로 선명하게 전시되어 표출이 되는 것이다.Then, the urethane liquid is filled on the vinyl chloride film 1 or the thermal transfer film la which is adsorbed on the mold 5 while the adhesive 2 is applied to the surface as described above, and then the release paper is placed on the surface. 9 Pressed and pressed with a conventional hot press plate 27, the urethane liquid is foamed and cured along the shape of the mold 5, and is good with the vinyl chloride film 1 or the thermal transfer film 1a by the adhesive agent 2. When the tape is detached from the mold plate 4 and then separated from the mold 5, it is possible to obtain the decoration of the present invention in which the wood grain is naturally emitted on the surface, and in the case of thermal transfer film paper la When the transparent film 1la is peeled off with the sixth (b) layer, the pattern layer 12a on the bottom surface is clearly displayed and displayed.

이와같은 제조되는 본 발명의 장식판은 원목판과 거의 동일하게 나무 무늬결이 인쇄된 염화비닐 필름지(l)나 열전사 필름지(la)가 몰드(5)의 형을 따라 진공 흡착된 상태에서 우레탄층(3)과 견고하게 융착되는 것이므로 장식판의 표면으로 나무 무늬결이 손상됨이 없이 선명하게 표출될 수 있어 원목판과 같은 느낌을 주는 것으로서 가구용 장식판으로 매우 상품성이 뛰어난 것이다.The decorative plate of the present invention manufactured as described above has a urethane layer (1) in which a vinyl chloride film (l) or a thermal transfer film (la) on which a wooden pattern is printed is vacuum-adsorbed along a mold 5 in a manner similar to a wooden board. 3) Because it is firmly fused together, the surface of the decorative plate can be clearly displayed without damaging the wood texture, giving the impression like a wooden board, and it is very good as a decorative plate for furniture.

따라서 본 발명에 의한 장식판을 가구에 사용할 경우 상당한 량의 원목장식판 대체 효과를 볼 수 있어 원목 수입에 따른 막대한 외화낭비를 줄일 수 있으며, 특히 제 7(c) 도와 같이 직물(13)을 이용한 염화비닐필름지(1)를 사용하여 장식판을 형성할 경우 가구용 장식판으로서 전혀 새로운 개념의 장식판을 제공할 수가 있으며, 이러한 장식판은 가구용 외에 건축 내장제로도 활용될 수가 있는 것으로서 용도가 매우 다양한 장식판이다.Therefore, when the decorative plate according to the present invention is used for furniture, a considerable amount of wood decorative plate replacement effect can be seen, which can reduce enormous foreign currency waste due to wood import, and in particular, vinyl chloride using the fabric 13 as shown in (c). When the decorative plate is formed using the film paper (1), it is possible to provide a decorative plate of a completely new concept as a decorative plate for furniture, and such a decorative plate is a decorative plate that can be used as a building interior material in addition to furniture.
