Description
본 발명은 플라스틱 제품 성형용 합성수지 사출 노즐에 관한 것으로서, 특히 합성수지 사출 노즐 내부 중앙에 위치한 밸브게이트 개폐용 밸브핀내에 수지 흐름탕도를 형성함을 특징으로한 플라스틱제품 제조용 합성수지 사출 노즐에 관한 것이다.The present invention relates to a synthetic resin injection nozzle for molding a plastic product, and more particularly, to a synthetic resin injection nozzle for manufacturing a plastic product, characterized in that the resin flow turbidity is formed in the valve gate opening and closing valve pin located in the center of the synthetic resin injection nozzle.
현재까지는 플라스틱제품 제조용 합성수지 사출 노즐은 도4에서 참조되는 바와 같이 중앙의 합성수지 흐름탕도(6)를 기준으로 외부에서 공급되는 수지 흐름탕도(미도시) 및 하부의 금형내 수지 공급용 밸브게이트(1)로 구성되어 있으나 이와 같은 구조는 평판 성형제품이 아닌 입체적인 각종 성형제품을 성형시에만 사용이 가능하고 앞으로 국내에서 많은 수요가 확실시되는 플라스틱 카드형 제품, 즉 신분증, 각종신용카드, 운전면허증 및 공중전화카드등과 같은 평판형 성형제품들을 성형하기에는 여러가지 어려움이 많았었다.Until now, the plastic injection nozzle for manufacturing plastic products has a resin flow ball (not shown) supplied from the outside based on the central resin flow ball 6 as shown in FIG. 4 and a valve gate for resin supply in the lower mold. Although it is composed of (1), such a structure is a plastic card type product that can be used only when molding various three-dimensional molded products, not flat plate molded products, and it is surely in high demand in Korea, namely identification card, various credit cards, driver's license There have been many difficulties in molding flat molded products such as public telephone cards.
특히 상기와 같은 평판형의 플라스틱 제품을 기존 사출성형기에 의하여 성형하게 되면 평판인 제품의 상하면에 플라스틱 성형점이 돌출되게 형성되어 외관상 및 사용상 많은 문제점이 있었다.In particular, when the flat plastic products of the above-mentioned type are molded by the conventional injection molding machine, plastic molding points are formed to protrude from the upper and lower surfaces of the flat products, and there are many problems in appearance and use.
본 발명은 상기한 바와 같은 평판 플라스틱 제품의 사출성형시 및 그 성형된제품의 사용시에 많은 문제점을 안고 있는 평판인 카드형 플라스틱 성형물의 사출성형용 노즐의 결점을 개량하여 평판형 플라스틱 제품의 표면에 성형시의 수지 배출공에 의한 돌출점(성형점)이 전혀 생기지 않도록 성형하기 위하여 수지흐름 탕도(6)내의 중앙에 위치한 밸브게이트(1) 개폐용 밸브핀(2)에 소형의 수지 흐름탕도를 천설한 노즐을 제공코져 하는 것으로서 이를 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.The present invention improves the defects of the injection molding nozzle of the card-shaped plastic molding, which is a flat plate having many problems in the injection molding of the flat plastic products as described above and the use of the molded product to the surface of the flat plastic products A small resin flow bath is placed on the valve pin 1 for opening / closing the valve gate 1 located in the center of the resin flow trough 6 so as not to cause any protruding point (molding point) by the resin discharge hole during molding. It will be described in detail with reference to the accompanying drawings as to provide a nozzle installed in the drawings as follows.

플라스틱 제품 제조용 합성수지 사출 노즐에 있어서, 금형(5)내로 수지를 공급하는 밸브게이트(1) 개폐용 밸브핀(2)의 수직방향 하단에 상부는 수지 인입공(4)을 Y자형으로 천설하고 하부는 상기 수지 인입공과 관통되게 L자형 소형수지 흐름탕도(3)나 ㅗ자형 소형수지 흐름탕도(3')중에서 선택된 어느 한가지 탕도를 밸브핀(2)하단 측면으로 향하도록 천설한 것으로 구성된 것이다.In the plastic injection nozzle for manufacturing a plastic product, the upper portion of the valve gate (1) opening and closing valve pin (2) for supplying the resin into the mold (5) in the vertical direction of the resin inlet (4) is laid in the Y-shaped Is formed by laying any one selected from the L-shaped small resin flow flow (3) or the U-shaped small resin flow flow (3 ') toward the bottom side of the valve pin (2) to penetrate the resin inlet hole will be.
이상과 같이 구성되는 밸브게이트(1) 개폐용 밸브핀(2)은 플라스틱 제품 성형시 합성수지가 통상의 성형 노즐에서와 같이 외부의 수지 흐름탕도를 통하여 주입되어 밸브핀(2)의 하단 상부의 Y자형 수지인입공(4)으로 수지가 인입된 후 L자형 소형 수지흐름탕도(3)나 ㅗ자형 소형 수지흐름탕도(3')를 통하여 밸브핀(2)의 일측으로나 양측으로 흘러내려 평판형 성형용 금형(5)에 주입되게 되므로 상하 평면이 매끈한 상태로의 성형물을 얻을 수 있게 된다.즉 본 발명 카드형 성형물 제조용 합성수지 사출 노즐은 탕도 중앙에 위치한 밸브핀 하단에 상부는 Y자형 하부는 L자나 ㅗ자형으로된 소형수지흐름탕도가 형성되어 있어서 평판형 금형에 수지를 측면으로 공급할 수 있어서 평판 성형물의 상하면에 수지흐름탕도에 의해 발생되는 돌출점이 생기지 않게 표면이 매끈한 제품을 얻을 수 있는 효과가 있다.The valve pin 1 for opening / closing the valve gate 1 configured as described above is injected with a synthetic resin through an external resin flow bath as in a conventional molding nozzle when molding a plastic product. After the resin is introduced into the Y-shaped resin inlet (4), it flows to one or both sides of the valve pin (2) through the L-shaped small resin flow diagram (3) or the U-shaped small resin flow diagram (3 '). Since it is injected into the flat mold (5), it is possible to obtain a molded article having a smooth upper and lower planes. That is, the synthetic resin injection nozzle for manufacturing the card-shaped molding of the present invention has a Y-shaped upper portion at the bottom of the valve pin located at the center of the water supply. The lower part is formed with L-shaped or U-shaped small resin flow muddy, so that the resin can be supplied to the flat mold side by side, so that the surface of the flat molded product does not have a protruding point caused by resin flow muddy. There is an effect that it is possible to obtain a shapely products.
