본 발명은 플라스틱 형틀을 이용한 액체합성수지 충진 성형 방법에 관한 것으로서, 더욱 상세하게는 금속금형에 액체상태의 합성수지를 충진하여 제품을 생산하던 것을 제작이 간편하고 단가가 매우 저렴한 플라스틱 형틀을 이용하여 합성수지 제품을 생산할 수 있게 하기 위한 것이다.The present invention relates to a method for filling and forming a liquid synthetic resin using a plastic mold, and more particularly, to produce a product by filling a synthetic resin in a liquid state into a metal mold, and using a plastic mold having a very low cost and a low cost. It is to be able to produce.
액체합성수지를 충진하여 제품을 성형하는 종래의 방법은, 먼저 생산하고자 하는 제품에 맞게 제작된 금형 내측에 사후에 생산될 제품과 금형과의 분리작업이 용이하게 이형제를 도포한 뒤에 금형내측에 액체상태의 합성수지를 충진하고 이를 장시간(12시간 이상)동안 경화시킨 다음, 금형에서 제품을 빼내어서 합성수지 제품의 성형작업을 완료하였다.In the conventional method of molding a product by filling a liquid synthetic resin, first, a mold release agent is easily applied to the inside of the mold manufactured for the product to be produced, and then a release agent is easily applied to the mold to separate the product from the mold. The resin was filled and cured for a long time (more than 12 hours), and then the product was removed from the mold to complete molding of the synthetic resin product.
그러나 이는, 상기와 같은 합성수지 제품을 충진 성형하기 위한 금형을 제작시 금형가공이 매우 어려웠으며, 그에 따른 금형 제작단가가 상승되었는데, 상기와 같은 고가의 금형에 액체합성수지를 충진시켜 이를 장시간 경화시키면서 제품을 생산해야하므로, 생산해야 하는 제품의 수량만큼 고가의 금형이 소요되게 되어 제품의 양산에 어려움이 있었고, 수많은 금형을 보관비치해야 하므로 그에따른 비용과 별도의 넓은 공간을 차지하게 되는 문제점이 있었다.However, this was very difficult to manufacture the mold for filling the synthetic resin products as described above, and the mold manufacturing cost was increased accordingly, by filling a liquid synthetic resin in the expensive mold as described above and curing the product for a long time Since it is necessary to produce, it is difficult to mass-produce the product as expensive molds are required as the quantity of the product to be produced, there is a problem that occupies a large space and separate costs according to the storage and storage of numerous molds.
또한, 상기 금형에서 성형완료된 제품을 쉽게 빼내기 위하여 금형내측에 이형제를 충분히 도포해야 하는 또 하나의 번거로운 공정이 소요되게 되어 또 하나의 공정을 관리하기 위한 비용과 공간 그리고 작업시간이 더 요구되게 되어 그에 따른 작업시간의 지연과, 생산원가 상승으로 생산성을 실추시키는 커다란 문제점을 안고 있었다.In addition, in order to easily remove the molded product from the mold, another cumbersome process of applying a mold release agent to the inside of the mold is required, which requires more cost, space, and work time to manage another process. Due to the delay of the working time and the increase of the production cost, there was a big problem that impaired productivity.
따라서, 본 발명은 상기와 같은 종래의 제반문제점들을 완벽하게 해소함과 동시에, 합성수지 성형제품 생산에 획기적인 방법을 제공하기 위한 것으로서, 종래의 금속금형 대신에 플라스틱 액체합성수지를 충진한뒤, 이를 경화시켜 제품을 생산할 수 있도록 하는 플라스틱 형틀을 이용한 액체합성수지 충진성형 방법을 제공하기 위한 것이다.Therefore, the present invention is to completely solve the above problems and at the same time, to provide a breakthrough method for the production of synthetic resin molded products, filling the plastic liquid synthetic resin instead of the conventional metal mold, and then cured the product It is to provide a liquid resin filling molding method using a plastic mold to produce a.
이하에서 본 발명의 내용을 상세하게 설명하면 다음과 같다.Hereinafter, the content of the present invention will be described in detail.
먼저 생산코져 하는 제품에 맞게 플라스틱 형틀을 성형 제작하되, 이 플라스틱 제작은 가공성이 매우 양호한 석고로서 생산코져하는 모형을 제작한뒤 상기 모형에 용해된 알루미늄을 부어 알루미늄 금형을 제작한후, 이 알루미늄 금형을 이용하여 상기 플라스틱 형틀을 성형 제작한다. 그뒤, 상기 공정에서 성형제작된 볼트부재로서 공정되는 밀봉 고정구를 이용하여 밀봉시킨 다음에, 플라스틱 형틀 상측에 액체합성수지 주입충진을 위한 주입구를 마련하고, 이 주입구를 통해 액체합성수지를 주입 충진시킨다.First, the plastic mold is molded and manufactured according to the product to be produced. This plastic production is made of gypsum with good processability, and then a model is produced to produce the aluminum mold by pouring molten aluminum into the model. Using to form the plastic mold. Then, after sealing using a sealing fixture which is processed as a bolt member manufactured in the above process, an injection hole for liquid resin injection filling is provided on the upper side of the plastic mold, and the liquid synthetic resin is injected and filled through the injection hole.
그뒤, 상기와 같이 주입된 액체합성수지를 경화시키고, 이렇게 성형된 제품에서 플라스틱 형틀을 벗겨내어 합성수지재 제품의 성형작업을 완료한다.Thereafter, the injected liquid synthetic resin is cured, and the plastic mold is peeled off from the thus molded product to complete molding of the synthetic resin product.
이때, 제품에서 플라스틱 형틀을 벗겨 낼때에는, 플라스틱 형틀과 제품이 서로 달라붙지 않아서 분리작업이 매우 간편하며 이 플라스틱 형틀의 가격이 매우 저렴하여 벗겨내면서 찢어버리거나 제품에 따라 벗겨내지 않아도 되는 것이다.In this case, when the plastic mold is peeled off from the product, the plastic mold and the product do not stick together, so the separation operation is very easy, and the price of the plastic mold is very low so that it does not have to be peeled off or peeled off depending on the product.
이와같이 방법에 의해 성형제작되는 제품을 첨부된 도면에 따라 본 발명의 일실시예를 들어 다시 한번더 설명하면 다음과 같다.Thus once again described for example an embodiment of the present invention according to the accompanying drawings the product manufactured by the method as follows.
첨부된 도면은 소정의 모양을 구비한 트랜스에 액체합성수지를 충진 성형시키는 것을 나타낸 것으로, 본 발명은 본 발명의 일실시예인 트랜스에 액체합성수지를 충진성형시키는 것과 같이 소정의 형상을 갖고 있는 제품에 합성수지를 몰딩시키는 제품과, 합성수지물로서만 성형되는 제품등에도 모두 적용이 가능한 것인데, 여기에서 본 발명의 일실시예를 첨부된 도면에 따라 설명하기로 한다.The accompanying drawings show filling and molding of a liquid synthetic resin in a transformer having a predetermined shape, and the present invention is a synthetic resin in a product having a predetermined shape such as filling and molding a liquid synthetic resin in a transformer, which is an embodiment of the present invention. It is possible to apply both to the molded products and products molded only as a synthetic resin, one embodiment of the present invention will be described in accordance with the accompanying drawings.
먼저 생산코져 하는 제품(트랜스)에 맞게 제작 형성된 플라스틱 형틀(1)에 트랜스(2)를 장착하면서 그 상측으로 또 한개의 플라스틱 형틀(1)를 정확하게 위치시킨다.First, while mounting the transformer (2) to the plastic mold (1) formed according to the product to be produced (trans), another plastic mold (1) is accurately positioned above it.
그 다음에 트랜스(2) 상하에 위치한 플라스틱 형틀(1)의 테두리 상, 하에 금속재로 된 밀봉고정구(3)를 이용하여 볼트부재(4)로서 상, 하측 플라스틱 형틀(1)과 트랜스(2) 코어를 견고하게 밀착고정시켜 액체합성수지 주입충진시 액체상태의 합성수지가 외부로 흘러나가지 않도록 완전밀봉시킨다.Then, the upper and lower plastic molds 1 and the transformer 2 are formed as bolt members 4 using the sealing fixtures 3 made of metal material on the upper and lower edges of the plastic mold 1 positioned above and below the transformer 2. The core is firmly fixed and tightly sealed so that the synthetic resin in the liquid state does not flow to the outside during filling.
여기에서 상기 밀봉고정구(3)는 상, 하측 플라스틱(1)을 밀봉시키고져 사용되는 것으로, 본 발명의 일예뿐만 아니라 모든 합성수지 성형물에 적용되는 것이다. 그뒤, 상측의 플라스틱 형틀(1)의 일측에 액체합성수지(5)를 주입충진하기 위한 주입구(1a)를 형성시켜야 하는데, 이 플라스틱 형틀(1)상의 주입구(1a) 형성작업은 일반적인 칼로서 필요한 부분만 오려내면 되는 것으로 그 작업이 매우 용이하다.Here, the sealing fixture 3 is used to seal the upper and lower plastics 1, and is applied to all synthetic resin moldings as well as an example of the present invention. Thereafter, an injection hole 1a for injection filling the liquid synthetic resin 5 must be formed on one side of the upper plastic mold 1, and the operation of forming the injection hole 1a on the plastic mold 1 is necessary as a general knife. It is very easy to work with just cutting out.
이렇게 형성된 주입구(1a)를 통해 액체합성수지를 주입하게 되면, 액체상태의 합성수지(5)는 플라스틱 형틀(1) 내측에서 제품사이 즉, 트랜스(2)의 각각의 코일사이의 미세한 공간과, 플라스틱 형틀(1) 내측면과 트랜스(2)간에 형성하는 각종 틈새로 스며들면서 목적하는 바대로 액체합성수지(5)가 충진되게 되고, 이것이 시간이 지남에 따라 경화되게 되면 상기 볼트부재(4)와 밀봉고정구(3)를 분리해낸뒤, 제품 상, 하측에 위치하고 있는 플라스틱 형틀(1)을 벗겨내어 합성수지 제품의 성형작업을 완료하게 되는 것이다.When the liquid synthetic resin is injected through the inlet 1a formed as above, the liquid synthetic resin 5 has a fine space between the products inside the plastic mold 1, that is, between each coil of the transformer 2, and the plastic mold. (1) The liquid synthetic resin (5) is filled as desired while penetrating into various gaps formed between the inner surface and the transformer (2), and when it is cured over time, the bolt member (4) and the sealing fixture After removing (3), the plastic mold (1) located above and below the product is peeled off to complete the molding of the synthetic resin product.
상기와 같은 본 발명은 종래의 금속금형과는 달리 플라스틱 형틀과 합성수지 제품이 서로 붙지 않게 되어 종래의 이형제 도포공정이 삭제되고 값이 매우 저렴한 플라스틱 형틀을 일회용으로 사용하여 합성수지 제품을 충진성형할 수 있게 되므로서, 적은 비용으로 단시간 내에 제품을 양산할 수 있어서, 상품경쟁력에서도 뛰어난 효과를 발휘할 수 있는 특출한 효과가 있는 것이다.Unlike the conventional metal mold, the present invention does not adhere to the plastic mold and the synthetic resin product so that the conventional mold release agent coating process is eliminated, and the plastic mold can be filled and molded using a very low-cost plastic mold for single use. Therefore, the product can be mass-produced within a short time at low cost, and there is an exceptional effect that can exert an excellent effect even in product competitiveness.
