이상에서 설명한 본 발명에 따르면, 선바이저를 성형하는 상하형(15,16)을 캐비티(25,26)의 둘레부를 따라 배치되는 열전도성재질의 외곽몰드(27)와, 외곽몰드(27)의 내부에 배치되며 열전도성이 상대적으로 낮은 내부몰드(28)로 구성하여, 선바이저 성형재료 적층재를 가압할 때 상기 외곽몰드(28)를 고주파용접장치와 같은 가열장치(21)에 의해 가열함으로써, 한 번의 동작으로 선바이저 윤곽형태의 둘레부를 따라서 외장필름(40,41)을 융착시킴과 동시에 완충시트(5,6)의 둘레부를 선바이저의 테두리형상에 맞도록 성형할 수 있어서, 성형동작이 간단하여 성형시간이 단축되면서도, 외곽몰드(28)만을 집중가열하므로 사용동력이 절감되고, 완충시트(5,6)의 둘레부가 선바이저의 형상에 맞게 열변형되어 성형되므로, 완충시트(5,6)가 가장자리부위에서 팽창되지 않으므로, 완충시트(5,6)의 팽창력에 의해 외장필름(40,41)을 부착상태에 반하여 분리시키는 힘이 작용되지 않기 때문에 부착상태가 양호하게 유지될 수 있다.According to the present invention described above, the upper and lower molds 15 and 16 for forming the sun visor are formed along the outer mold 27 of the thermal conductive material and the outer mold 27 arranged along the circumference of the cavity 25 and 26. It consists of an inner mold 28 disposed inside and having a relatively low thermal conductivity, thereby heating the outer mold 28 by a heating device 21 such as a high frequency welding device when pressurizing the sun visor molding material laminate. In one operation, the outer film 40 and 41 may be fused along the circumference of the sun visor contour, and the circumference of the buffer sheets 5 and 6 may be molded to fit the rim of the sun visor. Since the molding time is shortened and the molding time is shortened, the heating power of the outer mold 28 is reduced, and thus the driving power is reduced. 6) do not expand at the edges Because, the adhesion state can be well maintained since by the force of the buffer sheet (5, 6) it does not act to force the separation against an exterior film (40,41) in the attached state.

또한, 외곽몰드(27)의 캐비티(25,26)의 서로 맞닿는 엣지부에 수직선부(29)가 형성되므로, 외장필름(40,41)의 융착시에 용융재료가 압착되어 외부로만 밀려나가지 않고, 내측과 외측으로 균일하게 밀려나가므로, 용융부분이 외장필름(40,41) 의 양쪽에 형성되어 외장필름(40,41)의 부착력이 더욱 증대된다. 또한 외곽몰드(27)의 수직선부(29)의 외측에는 짧은 길이의 수평부(31)가 형성되어 외장필름(40,41)에 상당한 면적으로 접촉되어 용융시킬 수 있어서, 외장필름(40,41)이 충분히 가열되고 수지의 용출량도 증대되어 완충시트(5,6)가 견고하게 부착된다. 또한 본 발명에 따르면, 내부몰드(28)를 베이클라이트나 기타의 내열성수지(28)로 제작함으로써, 제작코스트를 낮추면서도, 가열장치의 전력소비를 최소화할 수 있다.In addition, since the vertical line portion 29 is formed at the edge portions of the outer molds 27 which are in contact with each other, the molten material is compressed and squeezed out of the outer molds 27 and 40. Since the inner and outer sides are uniformly pushed out, the molten portion is formed on both of the exterior films 40 and 41, and the adhesion of the exterior films 40 and 41 is further increased. In addition, a horizontal portion 31 having a short length is formed outside the vertical line portion 29 of the outer mold 27 to be in contact with the exterior films 40 and 41 with a substantial area, thereby melting the exterior films 40 and 41. ) Is sufficiently heated, the amount of resin eluted also increases, and the buffer sheets 5 and 6 are firmly attached. In addition, according to the present invention, by manufacturing the inner mold 28 to the bakelite or other heat-resistant resin 28, it is possible to minimize the power consumption of the heating device while lowering the manufacturing cost.

이하에서 도면을 참조하여 본 발명의 바람직한 실시예를 설명한다. 도 2는 본 발명의 일 실시예의 상하형의 개방상태도이고, 도 3은 상기 실시예의 상하형의 체결상태도이다. 도시된 바와 같이 본 발명에 따르면, 선바이저형태의 캐비티(25,26)가 형성된 상하형(15,16)이 프레스장치(1)에 설치되고, 이 프레스장치(1)의 일측에는 상하형(15,16)을 가열하기 위한 고주파용접장치로 된 가열장치(21)가 구비된다.Hereinafter, with reference to the drawings will be described a preferred embodiment of the present invention. Figure 2 is an open state diagram of the upper and lower dies of one embodiment of the present invention, Figure 3 is a fastening state diagram of the upper and lower dies of the embodiment. As shown, according to the present invention, upper and lower dies 15 and 16 having sun visor-type cavities 25 and 26 are provided in the press apparatus 1, and one side of the press apparatus 1 has an upper and lower dies ( A heating device 21 made of a high frequency welding device for heating 15 and 16 is provided.

상기 상하형(15,16)은 캐비티(25,26)의 둘레부에 배치되는 열전도성 재질, 바람직하게는 황동으로 제작된 외곽몰드(27)와, 이 외곽몰드(27)의 내부에 배치되며 상기 외곽몰드(27)보다 열전도성이 낮은 재질, 바람직하게는 베이클라이트와 같은 내열성수지로 제작된 내부몰드(28)로 구성된다. 상기 외곽몰드(27)의 형태를 살펴보면, 캐비티(25,26)의 엣지부에 형성되며 금형의 체결시에 서로 맞닿는 부분에는 수직선부(29)가 형성되고, 이 수직선부(29)의 안쪽에는 경사부(30) 또는 만곡부 가 형성된다.The upper and lower dies 15 and 16 are disposed in the outer mold 27, which is made of a thermally conductive material, preferably brass, disposed at the circumference of the cavity 25 and 26, and is disposed inside the outer mold 27. The inner mold 28 is made of a material having a lower thermal conductivity than the outer mold 27, preferably a heat resistant resin such as bakelite. Looking at the shape of the outer mold 27, a vertical line portion 29 is formed in the edge portion of the cavity (25, 26) and abutting each other when the mold is fastened, the inside of the vertical line portion 29 The inclined portion 30 or the curved portion is formed.

이러한 구조에 따르면 상하형(15,16) 사이에 선바이저 성형용 적층재를 투입하고 금형을 가압하여 체결하면, 가열장치(21)의 열이 캐비티(25,26)의 둘레부분의 외곽몰드(27)를 통해서 외장필름(40,41)의 가장자리부분이 집중적으로 융착되고 나머지 부분은 열에 의해 변형되지 않기 때문에, 성형재료의 외관이나 재질이 열변형되지 않아서 외관이 미려하면서도, 외장필름(40,41)의 둘레부가 융착된다. 이 때 도 4의 부분 확대도에 도시된 바와 같이, 캐비티(25,26)의 서로 맞닿는 엣지부에 수직선부(29)가 형성되므로, 이 수직선부(29)에 의해 가압되는 외장필름(40,41)이 용융되어 형성되는 버르 또는 용출물이 금형의 외부쪽으로만 쏠리지 않고 금형의 내측과 외측으로 균일하게 용출되므로, 용융부분이 외장필름(40,41)의 양쪽에 형성되고 부착면적이 증대되어 부착력이 증대된다.According to this structure, when the laminate for sun visor molding is put between the upper and lower molds 15 and 16, and the mold is pressurized and fastened, the heat of the heating device 21 is formed in the outer mold of the periphery of the cavities 25 and 26. 27, since the edges of the exterior films 40 and 41 are intensively fused and the remaining portions are not deformed by heat, the exterior or material of the molding material is not thermally deformed and the exterior is beautiful, but the exterior films 40, The periphery of 41) is fused. At this time, as shown in the partial enlarged view of Figure 4, since the vertical line portion 29 is formed on the edge portions of the cavities (25, 26) in contact with each other, the outer film 40, which is pressed by the vertical line portion 29, 41) is melted, but the eluate or eluate formed is not uniformly eluted to the inside and the outside of the mold without being directed only to the outside of the mold, the molten portion is formed on both sides of the outer film (40, 41) and the adhesion area is increased Adhesion is increased.

또한, 상기 외곽몰드(27)의 수직선부(29)의 외측에는 짧은 길이만큼 연장되는 수평부(31)가 형성되는데, 이 수평부(31)는 상하형(15,16)이 서로 맞닿을 때 외장필름(40,41)의 접촉면적을 증대시켜서 외장필름(40,41)이 충분히 가열되어, 수지의 용출량이 증대되어 외장필름(40,41)이 견고하게 부착될 수 있도록 한다. 외곽몰드(27)의 엣지부를 이루는 수평부(31)의 폭은, 상하형(15,16)이 닫힐 때 엣지부에 의해 외장필름(40,41)이 절단되지 않으면서 충분한 부착력을 확보할 수 있을 정도의 접촉면적을 확보할 수 있도록 정해진다. 이 수평부(31)의 폭은 외장필름(40,41)의 재료의 물성에 따라 정해지지만, PVC 필름을 외장필름(40,41)으로 사용하는 경우에는 적어도 1mm이상 되는 것이 바람직하다.In addition, the outer portion of the vertical line portion 29 of the outer mold 27 is formed with a horizontal portion 31 extending by a short length, the horizontal portion 31 when the upper and lower dies (15, 16) abut each other By increasing the contact area of the exterior films 40 and 41, the exterior films 40 and 41 are sufficiently heated to increase the elution amount of the resin so that the exterior films 40 and 41 can be firmly attached.
