본 고안은 성형물의 이형 효과와 성형물 표면의 광택효과에 의한 품질향상 및 금형의 산화방지등을 목적으로 한 신발 금형에 관한 것이다.The present invention relates to a shoe mold for the purpose of improving the quality and anti-oxidation of the mold by the release effect of the molding and the gloss effect of the surface of the molding.
일반적으로 신발 금형의 내면 즉, 성형물과 접촉되는 형구는 금형을 제작시에 미세하나마 요철면이 생기게 되고 이 요철면 때문에 성형물의 표면에 요철부가 생기게 되어 상품적 가치가 저하되고 특히 성형물을 탈형시에 접착 밀도가 높아서 이형이 까다롭고 이형시에 무리한 힘이 가해지면 제품이 손상되는 등의 문제가 있게 된다.In general, the inner surface of the shoe mold, that is, the mold sphere in contact with the molding has a fine but uneven surface at the time of manufacturing the mold, and the uneven surface causes unevenness on the surface of the molding, which lowers the merchandise value, especially when demolding the molding. Due to the high adhesive density, the mold is difficult to release and if excessive force is applied during the mold release, the product may be damaged.
또한, 금형이 금속제일 경우 쉽게 산화되는 문제가 있게되어 금형의 형구 내부나 접촉면에 크롬등을 이용한 도금방법으로 표면이 매끄럽고 이형 효과가 향상된 금형이 알려지고 있으나, 이와같은 금형도 몇번 사용하지 않아서 도금이 벗겨지거나 균열이 생기게 되고 표면이 거칠어지는 문제가 있게 되는 것이다.In addition, when the mold is made of metal, there is a problem that it is easily oxidized, and a mold having a smooth surface and a release effect is known by plating method using chromium on the inside of the mold or the contact surface of the mold. This may cause peeling or cracking and roughening of the surface.
이러한 제반 문제 때문에 금형에 도금하는 횟수가 잦게되며 도금에 소요되는 비용이 많으며 도금중에는 생산이 중단되는 폐단 때문에 많은 경제적 손실을 가져오게 되며 도금 직후에 금형을 사용하게 되면 성형 물에 생산도금액이 묻어 나오게 되어 불량품이 양산되는 폐단이 있게되는 것이다.Due to these various problems, the number of plating on the mold is frequent, the cost of plating is high, and a lot of economic loss is caused due to the closed end during the plating. When the mold is used immediately after plating, the plating solution is buried in the molding. It will come out, there is a waste of mass production of defective products.
본 고안은 상기와 같은 문제점을 해결하기 위하여 금형의 내면에 불소수지로 코팅층을 형성함으로 코팅된 표면에 흠집이나 요철이 생기지 않고 코팅층 자체가 내구성이 강해 균열이나 마모율이 낮으며, 아울러 이형효과가 뛰어나도록한 것으로 첨부도면에 의거 구조 및 작용효과를 설명하면 다음과 같다.In order to solve the above problems, the present invention forms a coating layer of fluorine resin on the inner surface of the mold to prevent scratches or irregularities on the coated surface, and the coating layer itself is durable, so that the crack or wear rate is low, and the release effect is excellent. When explaining the structure and effect according to the accompanying drawings as follows.
골형(1)과 형공(2) 및 형구(3)이 구성된 금형(a)(a')(a")에 있어서 금형 (a)(a")의 접면되는 내면과 금형(a')의 전체 표면에 불소수지로 적정 두께의 코팅층(4)가 형성되도록 한 것이다.In the mold (a) (a ') (a ") in which the bone mold (1), the hole (2), and the mold | die 3 were comprised, the inner surface of the mold (a) (a") and the whole of the mold (a') Fluorine resin on the surface is to form a coating layer 4 of the appropriate thickness.
이와 같이 된 본 고안의 작용 효과를 설명하면 다음과 같다.Referring to the effects of the present invention made as described above are as follows.
금형(a)(a")의 내면은 금형(a')의 상하면 또는 형공(2)에 내접되며 각 금형 (a)(a')(a")가 내접되는 부분에 각각 불소수지를 코팅함으로서 불소수지의 특성 때문에 코팅층(4)의 표면에 점막이나 요철 또는 균열이 없이 매끄럽고, 이 코팅층(4)와 접촉되는 성형물의 표면은 광택 효과가 우수하며, 아울러 이형 효과가 뛰어나게 되어 금형의 형구가 깊더라도 성형물이 쉽게 빠져 나오게 되고 성형물의 이형이 원활하여 제품 생산능력과 품질이 향상된다.The inner surface of the mold (a) (a ") is inscribed on the upper and lower surfaces of the mold (a ') or the mold hole (2), and the fluorine resin is coated on the respective portions where the molds (a) (a') (a") are inscribed, respectively. Due to the characteristics of the fluororesin, the surface of the coating layer 4 is smooth without mucous membranes, irregularities or cracks, and the surface of the molded product contacted with the coating layer 4 has excellent gloss effect and excellent release effect. Even if the molding is easily pulled out and the mold release is smooth, product production capacity and quality are improved.
본 고안은 종래 크롬 도금에 비하여 코팅 작업이 손쉽고 독성이 강한 도금액이나 특수 도금 장치가 필요없게 된다.The present invention is easier to coat than conventional chromium plating and does not require a strong plating solution or a special plating apparatus.
본 고안은 다만 크롬도금에 비하여 코팅재료의 원가가 상승되지만 코팅작업 과정에서 인력과 장치를 감소시킬수가 있고 코팅층(4)의 내구성이 우수하고 코팅 직후에도 바로 성형물을 제작할 수가 있어서 오히려 경제적인 잇점을 얻을 수 있게 되는 것이다.Although the cost of the coating material is higher than that of chromium plating, the present invention can reduce manpower and equipment in the process of coating, and it is excellent in durability because the coating layer 4 is excellent and a molding can be produced immediately after coating. You will get it.
다음은 참고적으로 본 고안 불소수지 코팅 방법과 종래 크롬 방법과 효과를 비교한 것이다.The following is a comparison of the effects of the present invention fluorine resin coating method and the conventional chromium method.
상술한 비교표에서 보는 바와 같이 본 고안 수지 코팅이 크롬 도금보다 원가가 상승되나 수명은 2배 이상이 되어 오히려 비용 절감의 효과가 있으며 금형의 개폐가 용이한 잇점을 얻게된다.As can be seen from the comparison table described above, the resin coating of the present invention has a higher cost than chromium plating, but its lifespan is more than two times, thereby reducing the cost and easily opening and closing the mold.
