제2a,b,c도는 본 발명의 실시과정을 나타낸 예시도.Figure 2a, b, c is an illustration showing an embodiment of the present invention.
제3도는 본 발명에 의하여 제조된 모조포도알의 단면도.3 is a cross-sectional view of the imitation grapes produced according to the present invention.
본 발명은 장식용으로 사용되는 모조포도알의 제조방법에 관한 것으로 포도알모양의 금형 외주면에 가소제가 첨가된 합성수지 페이스트를 피복시킨 후 가열, 냉각하여 합성수지가 완전히 굳어지기 전에 금형을 빼내므로서 포도알체의 외주면에 할합선이 나타나지 않는 모조 포도알을 제조하는 방법에 관한 것이다.The present invention relates to a method of manufacturing imitation grapes to be used for decoration by coating a plastic resin paste with a plasticizer added to the outer peripheral surface of the grape-shaped mold and heating and cooling to remove the mold before the synthetic resin is completely solidified The present invention relates to a method of manufacturing imitation grape grains that do not show a splitting line on its outer circumferential surface.
종래에도 합성수지로서 장식용의 모조포도알을 성형하는 방법이 알려졌으나, 종래의 방법은 할형금형을 이용한 사출 성형방법에 의한 것이므로 제품표면에 금형의 할합선 흔적이 남게되고 또한 촉감면에 있어서도 비교적 딱딱한 감촉을 주게되어 천연포도알과 다르게 보이므로 장식효과가 미흡하게되는 결합이 있었다.Conventionally, a method of molding decorative imitation grapes is known as a synthetic resin. However, since the conventional method is based on injection molding using a split mold, traces of a split line of the mold remain on the surface of the product and a relatively hard texture on the touch surface. There is a combination that gives a decorative effect is insufficient because it looks different from natural grapes.
본 발명은 전술한바의 종래 결점을 개선하기 위하여 포도알모양의 금형외주면에 합성수지 페이스트를 피복시켜 포도알체를 형성하므로서 외관면이나 촉감면에 있어서 천연 포도에 아주 근사한 모조포도알을 제공할 수 있게 한 것이다.The present invention is to coat the synthetic resin paste on the outer circumferential surface of the grape-shaped mold in order to improve the conventional drawbacks described above to form a grape grains to provide a counterfeit grapes that are very close to natural grapes on the outer surface or the touch surface will be.
본 발명은 전술한 발명의 목적을 달성하기 위하여 PVC121에 가소제인 DOP를 배합하여 가소성을 나타내도록한 합성수지 페이스트를 포도알 형상으로된 금형외주면에 피복시킨 후 합성수지 피복층이 어느정도 경화되지만 신축성이 남아 있을 때 피복층을 금형에서 벗겨내므로서 모형 포도알을 제조하는 바, 금형에 피복된 포도알 모양의 피복층을 벗겨내기 위하여는 꼭지부분의 구멍으로부터 금형이 빠져나와야 하므로 피복층이 완전히 경화되지 않고 충분한 신축성을 갖고 있을 정도로 경화되었을 때 금형에서 피복층을 벗겨내야 한다.In order to achieve the above object of the present invention, a synthetic resin paste, in which a plasticizer is added to PVC 121 and exhibited plasticity, is coated on a mold outer peripheral surface of a grape grain shape, and then the synthetic resin coating layer is hardened to some extent, but elasticity remains. The model layer is manufactured by peeling the coating layer from the mold. In order to peel off the grape-like coating layer coated on the mold, the mold must be ejected from the hole of the nipple so that the coating layer is not completely cured and has sufficient elasticity. When hardened to the extent, the coating should be stripped from the mold.
금형에 피복된 포도알모양의 피복층을 금형으로부터 분리시킬 때 합성수지 피복층의 신축성이 적으면 금형이 빠져나온 후 구멍의 구연부가 원상으로 수축되지 아니하는 경우가 있는 바, 이 경우에는 구연부에 가열된 금형을 마찰시켜 구연부를 수축시키므로서 구멍의 크기를 축소시켜야 한다.When separating the grape-like coating layer coated on the mold from the mold, if the elasticity of the synthetic resin coating layer is small, the hole portion of the hole may not shrink back to its original shape after exiting the mold. The size of the hole should be reduced by rubbing the shrinkage of the bulb.
[실시예]EXAMPLE
꼭지 부분(1′)과 지지부(1″)를 갖는 포도알 모양의 금형(1)을 대판(2)에 다수 입설하고 금형(1)을 60-100℃로 예열하여 그 외주면에 실리콘 오일을 도포건조한 다음 원료통(3)상단에 착설된 조절나사(4)(4′)의 상단에 금형(1)이 하향현가되도록 대판(2)을 올려놓는다.A large number of grape-shaped molds (1) having a stem (1 ') and a support (1 ″) are placed in the base plate (2), and the mold (1) is preheated to 60-100 ° C to apply silicone oil to the outer peripheral surface thereof. After drying, the
PVC 121 100부와 DOP 80부에 미량의 안료를 배합한 합성수지 페이스트(5)를 원료통(3)에 투입하고 실리콘오일이 도포처리된 금형(1)을 꼭지부분(1′)까지 잠기도록 합성수지페이스타(5)에 30초-1분간 담갔다가 빼어내어 금형(1)외주면에 합성수지 페이스트(5)가 피착되어 포도알 모양의 구상체(5′)가 피복 형성되게 한다.100 parts of PVC 121 and 80 parts of DOP are mixed with a synthetic resin paste (5) into the raw material container (3), and the silicone oil-coated mold (1) is immersed in the top part (1 '). Soak it in the
이와 같이 구상체(5′)가 피착된 금형(1)을 오븐속에서 가열하여 합성수지를 숙성하고, 물탱크 속에서 5초 내외로 표면만을 급냉하여 구상체(5′)의 내부는 여열이 잔존하는 상태에서 구상체(5′)을 금형(1)으로 부터 뽑아내면 꼭지부분이 확개되었다. 신축되면서 이형되어 작은 구경의 꼭지구멍(6′)을 갖는 모조포도알(6)의 완제품을 얻을 수 있는바, 이때 이형후 꼭지구멍(6′)의 축소원상 복원이 비정상적으로 될 경우에는 뽑아낸 금형(1)의 잔류열로서 구멍부분을 원상으로되게 축소시킨다.In this way, the mold 1 to which the spherical body 5 'is deposited is heated in an oven to ripen the synthetic resin, and the surface of the spherical body 5' remains inside by quenching only the surface within 5 seconds in the water tank. When the spherical body 5 'was pulled out from the mold 1 in the state of being made, the stem part was expanded. Stretched and deformed to obtain a finished product of imitation grape grains 6 having small apertures 6 '. At this time, if the original restoration of the aperture 6' is abnormal after release, it is extracted. As the residual heat of the mold 1, the hole portion is reduced to the original shape.
이와 같이 본 발명에 의하면 단인체의 구상금형을 이용하여 가소제가 적량 배합된 합성수지를 피착시켜 제조하므로서 포도알 표면에 하등의 할합선흔적이 없이 매끄럽고 윤택하게 성형됨은 물론 손으로 만질 경우에도 적당한 탄력성이 나타내므로 천연포도와 똑같은 외관과 절감이 나타나게 되어 장식효과를 보다 향상시킬 수 있는 것이다.As described above, according to the present invention, a synthetic resin containing a suitable amount of plasticizer is deposited using a spherical mold of a single human body, so that the surface of the grains can be smoothly and smoothly formed without any splitting traces. Therefore, the same appearance and savings as natural grapes appear, which can improve the decorative effect.
