본 발명은 문양고무 성형용 비접착성 불소화 폴리에틸렌 수지를 이용한 형 제작방법에 관한 것이다.The present invention relates to a mold fabrication method using a non-adhesive fluorinated polyethylene resin for patterned rubber molding.

종래에는 조각기나 밀링 등을 이용하여 금속에 음각을 조성하고 그 음각에 혼합된 고무를 주입한 다음 압착하여 고무에 양각문양을 성형하게 되는데 이렇게 고무에 양각문양을 성형하는 금속에 음각문양을 조각하기 위하여는 비용도 많이 들고 작업시간이 많이 소요될 뿐만 아니라 조밀하고 미세한 문양의 형을 제작하기가 어려워 조밀하고미세한 문양을 성형할 수 없는 폐단이 있는 것이다.Conventionally, by using engraver or milling, the intaglio is formed on the metal, the rubber mixed with the intaglio is injected, and then the stamp is pressed to form an embossed pattern on the rubber. In order to be expensive and time-consuming to work, it is difficult to produce a dense and fine pattern mold, there is a closure that can not form a dense and fine pattern.

본 발명은 이러한 점을 감안하여 문양의 양각으로 부식 성형된 금속부식판으로 음각의 비접착성 불소화 폴리에틸렌 수지의 형을 성형하므로서 금속부식판에 양각문양을 부식성형하게 되어 조밀하고 미세한 문양도 간편하게 성형하고 최종의 형을 비접착성 불소화 폴리에틸렌 수지로 형성하므로서 금속형인 경우와 같이 양각문양을 성형하기 위한 고무제품이 달라붙는 단점을 보완하기 위해 이형제를 사용하지 않아도 되는 등의 효과가 있는 것으로서 각 공정 및 도면에 의거 상세히 설명하면 다음과 같다.In view of the above, the present invention forms a mold of a non-adhesive non-adhesive fluorinated polyethylene resin with a metal corrosion plate formed by an embossed pattern, thereby embossing the embossed pattern on the metal plate, thereby easily forming a dense and fine pattern. And the final mold is formed of a non-adhesive fluorinated polyethylene resin, so that it is not necessary to use a release agent in order to compensate for the disadvantage that the rubber products for forming the embossed patterns stick together as in the case of the metal mold. When described in detail based on the drawings as follows.

제1공정 : 필림에 양각을 조성하기 위한 문양을 성형하여 문양부분 이외의 부분이 부식되는 양각을 조성하기 위한 필림(1)을 만든다.First step: A film (1) is formed to form an embossed portion in which a portion other than the pattern portion is corroded by forming a pattern for embossing the film.

제2공정 : 문양(2)이 그려진 양각을 조성하기 위한 필림(1)을 금속부식판(3)에 접착하여 금속부식판(3)을 부식시키면 문양(2)부분 이외의 부분이 부식되어 양각문양(4)의 금속부식판(3)을 얻게 된다.2nd process: When the film 1 for forming the embossed pattern 2 is attached to the metal corrosion plate 3 to corrode the metal corrosion plate 3, portions other than the pattern 2 are corroded and embossed. The metal corrosion plate 3 of the pattern 4 is obtained.

제3공정 : 제2공정에 의해 얻어진 양각문양(4)이 금속부식판(3)을 금속틀(5)에 안착시킨다.Third step: The relief pattern 4 obtained by the second step seats the metal corrosion plate 3 on the metal frame 5.

제4공정 : 양각문양(4)의 금속부식판(3)이 안착된 금속틀(5)에 비접착성 불소화 폴리에틸렌 수지(6)를 주입하고 압착하여 금속부식판(3)의 양각문양(4)에 의해 불소화 폴리에틸렌 수지(6) 저면에 음각문양(7)이 성형된다.Fourth step: A non-adhesive fluorinated polyethylene resin (6) is injected into the metal frame (5) on which the metal corrosion plate (3) of the embossed pattern (4) is seated and pressed to form an embossed pattern (4) of the metal corrosion plate (3). The engraved pattern 7 is formed on the bottom surface of the fluorinated polyethylene resin 6).

제5공정 : 금속틀(5)에서 불소화 폴리에틸렌 수지(6)형을 소정한 후, 분리해내면 음각문양(7)의 불소화 폴리에틸렌 수지(6)로 된 형을 얻게된다.Fifth Step: After the fluorinated polyethylene resin (6) type is specified in the metal frame (5), the fluorinated polyethylene resin (6) in the engraved pattern (7) is obtained.

이렇게 얻은 음각문양(7)의 불소화 폴리에틸렌 수지(6)로 된 형에 혼합된 고무성형물(10)를 삽입하여 히터상판(8)과 히터하판(9)으로 압착하면 원하는 양각문양(4)이 성형된 고무성형물(10)을 얻게되는 것이며 상기와 같이 금속부식판(3)에 양각을 조성하기 위한 필림(1)으로 금속을 부식시켜 문양을 성형하므로서 조밀하고 미세한 문양도 간단하게 성형하게 되며 고무성형물(10)을 성형하는 최종의 형을 비접착성 불소화 폴리에틸렌 수지(6)로 형성하므로서 종래의 금속형에서와 같이 고무성형물(10)이 달라붙는 것을 방지하기 위해 이 형제를 사용하지 않아도 되는 등의 특징이 있는 것이다.When the rubber molding 10 mixed in the mold of the fluorinated polyethylene resin (6) of the intaglio pattern (7) thus obtained is inserted and pressed into the heater upper plate (8) and the heater lower plate (9), the desired relief pattern (4) is formed. It is to obtain a rubber molding (10) and to form a pattern by corroding the metal with a film (1) for forming an embossed on the metal corrosion plate (3) as described above to form a dense and fine pattern simply and rubber molding The final mold for molding (10) is formed of a non-adhesive fluorinated polyethylene resin (6), so that it is not necessary to use this sibling to prevent the rubber molding 10 from sticking as in the conventional metal mold. There is a characteristic.
