Description

열경화성 수지 사출장치{Thermosetting resin Injection device}Thermosetting resin injection device {Thermosetting resin Injection device}

본 발명은 열경화성 수지 사출장치에 관한 것으로, 보다 구체적으로는 소형 열경화성 수지 제품을 사출기 없이 생산 가능 서보모터를 통하여 정밀 계량 및 토출이 가능하며, 열경화성 수지 전용 사출기 없이 금형의 형개/형폐(Open/Close)만으로 열경화성 수지 제품이 생산 가능한 열경화성 수지 사출장치에 관한 것이다.The present invention relates to a thermosetting resin injection device, and more specifically, to a small-sized thermosetting resin product without an injection machine, capable of precise metering and dispensing through a servo motor, and opening/closing (open/close) of a mold without an injection machine dedicated to thermosetting resin. ) relates to a thermosetting resin injection device capable of producing thermosetting resin products only.

일반적으로 열경화성 수지 사출장치는 금형 내부에 액상 원재료인 열경화성 수지을 주입하여 캐비티에 충진하고 가열된 금형에서 경화 및 취출하는 시스템이다.In general, a thermosetting resin injection device is a system that injects a thermosetting resin, which is a liquid raw material, into a mold, fills a cavity, and hardens and ejects the mold from a heated mold.

여기에서 적용되는 액상실리콘고무(Liquid Silicon Rubber; 이하 '열경화성 수지'라고 함)는 유연성을 갖는 탄성원료로써 가격이 비싼 반면에 내열성이 좋고, 탄성의 내구성 및 감촉이 좋기 때문에 널리 이용되고 있다.Liquid silicone rubber (hereinafter referred to as 'thermosetting resin') applied here is an elastic raw material having flexibility and is expensive, but is widely used because it has good heat resistance, elasticity durability and good touch.

열경화성 수지로 적용되는 수지는 LSR, 폴리우레탄, 에폭시 등 다양한 수지가 적용될 수 있다.Various resins such as LSR, polyurethane, and epoxy may be applied as the resin applied as the thermosetting resin.

또한, 필러를 함유한 것은 수축률이 거의 발생하지 않고, 전처리 코팅 없이 복합 접착 성형이 가능하여 고기능성 및 고부가가치를 도모할 수 있으며, 저점도 상태를 유지하므로 저압 성형이 가능하며 봉지물을 손상하지 않는 이점을 가지고 있다.In addition, those containing fillers have almost no shrinkage, and composite adhesive molding is possible without pretreatment coating, so high functionality and high added value can be achieved. has the advantage of not

이러한 열경화성 수지는 플라스틱사출과 다른 개념으로, 상온의 원재료와 경화제를 장비에 공급하고, 스텍틱믹스를 이용하여 교반 후 스쿠류로 공급하여 150 ~ 200℃의 금형에 경화시키는 방법을 주로 사용하며, 플라스틱사출과는 온도차이라고 생각되나 반응하는 구조 및 화학식 전체가 전혀 다른 개념이다.This thermosetting resin is a concept different from plastic injection, and mainly uses a method of supplying raw materials and curing agents at room temperature to equipment, stirring them using a static mix, supplying them to a screw, and curing them in a mold at 150 ~ 200 ° C. It is thought to be a difference in temperature from injection, but the entire reacting structure and chemical formula are completely different concepts.

그러나 위와 같은 플라스틱사출장비와 액상실리콘장비는 모두 열경화성 수지의 사출에는 이용할 수 없었으며 현재의 장비를 구입하여 수정하는 것 역시 불가능한 것임을 알게 되었다.However, it was found that both the above plastic injection equipment and liquid silicone equipment could not be used for injection of thermosetting resin, and it was also impossible to purchase and modify the current equipment.

즉, 열경화성 수지의 가장 중요한 온도관리 문제를 해결할 수 없었고, 믹싱 및 탈포가 완료된 열경화성 수지는 40 ~ 70℃의 금형에 들어가기 전까지 공기 중의 수분과 노출이 되지 않아야 하며, 기포나 이물질이 절대로 발생하면 안되는 재료이기 때문이다.In other words, the most important temperature management problem of thermosetting resin could not be solved, and the thermosetting resin after mixing and defoaming should not be exposed to moisture in the air until it enters the mold at 40 ~ 70 ℃, and bubbles or foreign substances should never occur. Because it is a material.

또한, 기존의 플라스틱사출장비 및 액상실리콘장비보다 교반이 훨씬 정교해야하기 때문에 기존의 장비를 가지고는 주형 우레탄의 물성을 유지하는데 어려움이 있었다.In addition, it was difficult to maintain the physical properties of molded urethane with existing equipment because stirring had to be much more sophisticated than conventional plastic injection equipment and liquid silicone equipment.

한편, 특허문헌 1은 고무계열 또는 실리콘계열 중 어느 하나 이상의 원재료가 저장되는 원재료저장부와, 원재료저장부로부터 원재료를 공급받고, 공급받은 원재료와 하나 이상의 착색제를 혼합하여 액상실리콘고무를 제조하는 재료제조부와, 재료제조부로부터 공급받은 액상실리콘고무의 토출량을 조절하는 정량조절밸브와, 정량조절밸브로부터 토출된 액상실리콘고무를 공급받되, 내부에 회전되는 스크류가 형성되는 스크류챔버부와, 스크류챔버부로부터 공급받은 액상실리콘고무의 분출량을 조절하여 액상실리콘고무를 금형부에 분출시키는 정량분출부로 구성되는 액상실리콘고무용 사출성형장비를 제안하였다.On the other hand, Patent Document 1 discloses a raw material storage unit in which one or more of the rubber-based or silicone-based raw materials are stored, and a material for preparing liquid silicone rubber by receiving raw materials from the raw material storage unit and mixing the supplied raw materials with one or more colorants. A manufacturing unit, a quantitative control valve for controlling the discharge amount of the liquid silicone rubber supplied from the material manufacturing unit, a screw chamber unit receiving the liquid silicone rubber discharged from the quantitative control valve and forming a screw rotating therein, and a screw An injection molding equipment for liquid silicone rubber is proposed, which consists of a constant injection part that ejects liquid silicone rubber into the mold part by controlling the amount of liquid silicone rubber supplied from the chamber part.

하지만, 전술한 선행기술은 2액형으로 상온에서 작업이 가능하나, 액상의 실리콘과 경화제의 혼합 상태에서 사출장치로의 원활한 이송이 어려울 뿐만 아니라, 혼합물의 상태에 따라 정량 제어가 용이하지 못하여 사출물의 품질이 저하되는 문제점이 있다.However, the above-mentioned prior art is a two-component type and can be operated at room temperature, but it is difficult to smoothly transfer to an injection device in a mixed state of liquid silicone and a curing agent, and it is not easy to control the quantity according to the state of the mixture. There is a problem of deterioration in quality.

특히, 휴대폰의 수밀 기능을 개선한 방수폰과 같은 경우, 열경화성 수지의 공급시, 0.15 ~ 0.2CC의 용량으로 공급이 이루어지도록 정밀 제어가 이루어져야 하는데 정량 제어가 용이하지 못한 선행기술에 의해서는 달성할 수 없을 뿐만 아니라, 제어가 불안정하여 휴대폰 케이스 등의 생산성 및 품질 저하의 주된 요인이 되고 있는 실정이다.In particular, in the case of waterproof phones with improved watertightness of mobile phones, when supplying thermosetting resin, precise control must be performed so that the supply is made in a capacity of 0.15 ~ 0.2CC. In addition, control is unstable, which is a major factor in deteriorating productivity and quality of mobile phone cases.

도 1에 의하면 종래에는 열경화성 수지 전용 사출기를 통해 계량 및 사출되는 사출금형(Mold)을 형개/형폐하여 열경화성 수지 제품을 성형할 수 있으며, 노즐의 Open/Close를 통해 금형에 열경화성 수지를 제공하되, 액상의 실리콘과 경화제를 각각 제공하는 원료공급장치(Dosing Machine)를 통해 처리장치(Processing Unit)를 통해 실리콘과 경화제를 적절한 압력으로 혼합하에 사출금형에 제공할 수 있다.According to FIG. 1, a thermosetting resin product can be molded by opening / closing an injection mold that is conventionally metered and injected through an injection molding machine dedicated to thermosetting resin, and providing a thermosetting resin to the mold through the opening / closing of the nozzle, Silicone and a curing agent may be supplied to an injection mold under mixing at an appropriate pressure through a processing unit through a dosing machine providing liquid silicone and a curing agent, respectively.

그러나, 종래 고가의 열경화성 수지 사출기 구비하여 열경화성 수지 생산을 위하여 별도의 전용 사출기를 구비해야 하므로 사출을 위한 장비의 원가가 상승되며, 기존 플라스틱 사출기 활용하기 위해 전용으로 사출기를 열경화성 수지 전용으로 개조해야만 생산 가능하므로 신규 설비 투자비 및 사출기 개조 비용 증가되는 문제점이 있다.However, since a separate injection molding machine must be provided for the production of thermosetting resin with a conventional expensive thermosetting resin injection molding machine, the cost of equipment for injection increases, and the injection machine must be remodeled exclusively for thermosetting resin in order to utilize the existing plastic injection molding machine. Since it is possible, there is a problem in that new facility investment cost and injection molding machine remodeling cost increase.

더불어, 열경화성 수지 전용 사출기를 설치할 공간 확보가 필요하므로 사출기 유지 보수해야 하며, 열경화성 수지 특성상 정기 유지보수를 위하여 분해 세척을 진행해야 하고, 소비자의 임의 분해 점검이 어렵고 판매처 AS 진행 시 비용이 주기적으로 발생 사출기 유지 보수의 어려움과 보수 비용이 증가되는 문제점이 있다.In addition, since it is necessary to secure space to install an injection molding machine dedicated to thermosetting resin, maintenance of the injection molding machine is required, and due to the nature of thermosetting resin, disassembly and washing must be performed for regular maintenance, and it is difficult for consumers to disassemble and inspect at will, and costs are incurred periodically when performing AS at the sales company. There is a problem in that the maintenance of the injection molding machine is difficult and the maintenance cost is increased.
