일반적으로 사출성형은 열가소성 플라스틱 또는 열경화성 플라스틱 성형재료를 사출성형기 내에서 가열 용융한 후, 스크루를 통해 사출금형의 캐비티 내로 가압 주입하여 충전하고, 이를 고화 또는 경화하여 성형품으로서 꺼내는 성형방법이다.In general, injection molding is a molding method in which a thermoplastic or thermosetting plastic molding material is heated and melted in an injection molding machine, and then press-filled into a cavity of an injection mold through a screw, and solidified or cured and taken out as a molded product.

상기 사출성형용 금형에 있어서, 용융된 재료는 스프루, 런너 및 게이트 등의 주입공간을 통하여 성형품의 성형공간인 금형의 캐비티 내로 주입되어 성형되고, 성형이 완료된 후에는 밀판이 동작하여 밀핀이 승강하면서, 게이트와 성형품의 연결부분이 분리되어, 런너와 게이트 및 성형품이 분리되면서 취출된다.In the injection molding die, the molten material is injected into the cavity of the mold, which is a molding space of the molded article, through injection spaces such as sprues, runners, and gates, and after the molding is completed, the mill plate is operated to push up the pin. At the same time, the connection portion between the gate and the molded article is separated, and the runner, the gate, and the molded article are separated and taken out.

이와 같은 성형품의 취출 과정에서 성형품을 캐비티로부터 분리해내기 어렵 게 장애를 주는 부분을 통상 언더컷이라 하고, 통상 하부나 측부 등 한부분에만 언더컷이 있는 경우에는 슬라이드 코어를 해당 부분에 맞게 이동시켜 간단하게 처리하였으나, 2개이상의 언더컷이 서로 상이한 각도록 형성되는 경우에는 처리가 용이하지 않았다.The part which makes it difficult to separate the molded part from the cavity during the ejection of the molded part is generally called an undercut.If there is an undercut only in one part such as the lower part or the side part, the slide core is moved to the corresponding part and simply However, the treatment was not easy when two or more undercuts were formed to be different from each other.

이러한 문제점을 해결하기 종래에는 각각의 언더컷에 해당하는 위치에 슬라이드 코어를 다중 내지 다중으로 형성하여, 금형의 개형시에 복수개의 슬라이드 코어가 각개 동작하면서 다수개소에 언더컷을 처리하도록 하고 있으나, 이러한 2개이상의 슬라이드 코어를 사용할 경우, 사출성형장치 내에 복수개의 슬라이드코어를 배치하여야 하므로 설계가 용이하지 않고 구성이 복잡해지며, 유지/보수 또한 용이하지 않은 문제점이 있었다.In order to solve this problem, conventionally, a plurality of slide cores are formed at a position corresponding to each undercut, so that the plurality of slide cores are individually operated when the mold is remodeled, and the undercuts are processed at a plurality of places. When more than one slide core is used, a plurality of slide cores must be disposed in the injection molding apparatus, so that the design is not easy, the configuration is complicated, and the maintenance / maintenance is not easy.

상기한 문제점을 해결하기 위한 본 고안의 목적은 금형의 구성이 간단하도록 단일의 슬라이드 코어를 이용하여 서로 상이한 각도로 형성되는 2개 이상의 언더컷을 처리하기 위한 다중 언더컷 취출을 위한 슬라이드 코어를 제공하는 데 있다.An object of the present invention for solving the above problems is to provide a slide core for taking out multiple undercuts for processing two or more undercuts formed at different angles using a single slide core to simplify the configuration of the mold. have.

이하 본 고안의 실시예를 첨부된 도면을 참조하여 살펴본다.Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

도 1은 본 고안에 따른 다중 언더컷 취출을 위한 슬라이드 코어를 전체적으로 나타내는 구성도이고, 도 2a 내지 2b는 도 1의 A-A'선을 절단하여 슬라이드봉의 작동상태를 나타내는 구성도이며, 도 3a 내지 3b는 도 1의 B-B'선을 절단하여 슬라이드코어의 작동상태를 나타내는 구성도이다.1 is a configuration diagram showing a slide core for taking out multiple undercuts according to the present invention as a whole, Figures 2a to 2b is a configuration diagram showing the operating state of the slide bar by cutting the line AA 'of Figure 1, Figures 3a to 3b is a configuration diagram showing the operating state of the slide core by cutting the line B-B 'of FIG.

본 고안은 다중 언더컷 취출을 위한 슬라이드 코어에 관련되며, 이때 다중 언더컷 취출을 위한 슬라이드 코어는 상·하원판(1)(2)상에 설치되는 상·하금형(1a)(2a)의 일측방면에 중복적으로 형성되면서 서로 상이한 각을 이루는 다중 언더컷을 간단한 금형구조로 취출하기 위해 슬라이드코어(10), 슬라이드공(20), 슬라이드봉(30) 등을 주요구성으로 이루어진다.The present invention relates to a slide core for taking out multiple undercuts, wherein the slide core for taking out multiple undercuts is one side of the upper and lower dies (1a) (2a) installed on the upper and lower plates (1) (2). In order to take out multiple undercuts having different angles while being overlapped with each other in a simple mold structure, the slide core 10, the slide hole 20, the slide rods 30, etc. are formed as main components.

본 고안에 따른 슬라이드코어(10)는 상원판(1)상에 경사지게 돌출되는 제1작동캠(12)과 미끄럼운동되어 하원판(2)상에서 슬라이드이송되면서 언더컷을 처리한다. 슬라이드코어(10)는 하원판(2)상에서 좌우슬라이드이송은 허용되면서 상하 유격이 방지되도록 가이드레일상에 맞물리도록 설치되고, 상원판(1)의 제1작동캠(12)과 대응하는 위치에 제1작동공(12a)이 경사지게 결합된다.The slide core 10 according to the present invention slides with the first operation cam 12 protruding obliquely on the upper plate 1 and slides on the lower plate 2 to process the undercut. The slide core 10 is installed to engage on the guide rails to allow the left and right slide transfer on the lower plate 2 to prevent the vertical play, and to correspond to the first operation cam 12 of the upper plate 1. The first operating hole 12a is inclinedly coupled.

이에 상원판(1)이 승·하강작동되면, 제1작동캠(12)과 제1작동공(12a)의 미 끄럼운동으로 슬라이드코어(10)가 좌우슬라이드이송되면서 언더컷을 처리하게 된다.When the upper plate 1 is moved up and down, the slide core 10 is moved to the left and right slides by the sliding movement of the first operation cam 12 and the first operation hole 12a to process the undercut.

이때, 상기 슬라이드코어(10)는 일단에 하부경사레일(14)이 형성되고, 하부경사레일(14)과 대응하는 상원판(1)상에 상부경사레일(16)이 미끄럼운동되도록 구비된다. 이는 슬라이드코어(10)가 제1작동캠(12)과 제1작동공(12a)의 미끄럼운동에 의해 형합시 도 3에 도시된 바와 같이 상·하부경사레일(16)(14)이 서로 맞물려 미끄럼운동되면서 슬라이드코어(10)를 가압하므로 금형이 더욱 긴밀하게 형합되는 이점이 있다.In this case, the slide core 10 has a lower slope rail 14 formed at one end thereof, and is provided such that the upper slope rail 16 slides on the upper plate 1 corresponding to the lower slope rail 14. This is because the upper and lower inclination rails 16 and 14 are engaged with each other as shown in FIG. 3 when the slide core 10 is formed by sliding the first operating cam 12 and the first operating hole 12a. Since the slide core 10 is pressed while sliding, the mold is more closely bonded.

한편, 상기 슬라이드코어(10)는 좌우슬라이드이송시 설치된 위치에서 정지되도록 저면에 스톱홈(10a)과, 스톱홈(10a)과 맞물리도록 하원판(2)상에 볼플랜저(10b)가 구비되는 것이 바람직하다.On the other hand, the slide core 10 is provided with a ball stopper (10b) on the lower plate (2) to engage the stop groove (10a) and the stop groove (10a) on the bottom so as to stop at the position installed during the left and right slide transfer It is preferable.

또한, 본 고안에 따른 슬라이드공(20)은 슬라이드코어(10)상에 관통되고, 슬라이드코어(10)의 이송방향과 상이한 각으로 구비된다. 슬라이드공(20)은 후술하는 슬라이드봉(30)이 슬라이드이송가능하게 삽입설치되는 설치부로써, 상기 슬라이드코어(10)에 의해 처리되는 언더컷과 상이하게 형성되는 다른 언더컷의 형성위치 및 각도를 고려하여 형성된다. 그리고 슬라이드공(20)은 슬라이드봉(30)이 삽입되어 스프링(S)의 탄성력에 의해 복원력이 작용할 수 있도록 슬라이드봉(30)과 스프링(S)이 삽입설치되는 공간이 서로 다른 직경으로 형성된다.In addition, the slide hole 20 according to the present invention penetrates on the slide core 10 and is provided at an angle different from the conveying direction of the slide core 10. The slide hole 20 is an installation part in which the slide rod 30, which will be described later, is inserted to be slide-movable, and is formed in consideration of the formation position and angle of another undercut formed differently from the undercut processed by the slide core 10. Is formed. And the slide hole 20 is a slide rod 30 is inserted into a space in which the slide rod 30 and the spring (S) is installed to have a different diameter so that the restoring force acts by the elastic force of the spring (S). .

본 고안에 따른 슬라이드봉(30)은 슬라이드공(20)상에 스프링(S)과 함께 삽입설치되고, 상원판(1)상에 돌출되는 제2작동캠(32)과 미끄럼운동되도록 맞물려 슬 라이드이송되면서 다른 언더컷이 처리된다. 슬라이드봉(30)은 슬라이드코어(10)상에 설치되되, 상기 슬라이드공(20)의 형성위치 및 각도에 따라 슬라이드코어(10)와 서로 상이한 이송방향을 가지고, 후단부가 제2작동캠(32)과 경사면으로 맞물려 미끄럼운동되면서 이송이 제어되어 다른 언더컷을 처리하게 된다.The slide bar 30 according to the present invention is inserted into the slide hole 20 with the spring (S) is installed, the sliding engagement with the second operation cam (32) protruding on the upper plate (1) slides As it is transported, another undercut is processed. The slide rod 30 is installed on the slide core 10, and has a different transfer direction from the slide core 10 depending on the position and angle of the slide hole 20, the rear end of the second operation cam (32) ) And the inclined surface is slid and the feed is controlled to handle another undercut.

이때, 도 1에서 슬라이드봉(30)의 설치개수를 1개로 도시하고 있지만, 이에 국한되지 않고, 언더컷의 처리개수에 따라 슬라이드공(20) 및 슬라이드봉(30)을 추가로 더 구비하는 구성도 가능하다.In this case, although the number of installation of the slide rod 30 is shown as one in FIG. 1, the configuration is not limited thereto, and further includes a slide hole 20 and a slide rod 30 according to the number of undercuts. It is possible.

이와 같이 구성된 본 고안의 작동예를 살펴보면, 우선 용융된 재료가 성형품의 성형공간인 금형의 캐비티 내로 주입되어 성형이 완료되면, 상원판(1)이 상승되면서 상·하금형(1a)(2a)을 개방하되, 이때 도 2a 내지 2b와 같이 제2작동캠(32)이 먼저 승강하면 슬라이드봉(30)이 스프링(S)의 탄성력에 의해 슬라이드공(20)상에서 후퇴하면서 일측의 언더컷이 처리됨과 동시에 도 3a 내지 3b처럼 제1작동봉(12)이 승강되면서 제1작동공(12a)과 미끄럼운동되어 슬라이드코어(10)를 후퇴시킴으로 다른측의 언더컷이 처리된다.Referring to the operation example of the present invention configured as described above, first, when the molten material is injected into the cavity of the mold, which is the molding space of the molded product, and the molding is completed, the upper plate 1 is raised and the upper and lower molds 1a and 2a are raised. 2A to 2B, the second actuating cam 32 is first lifted as shown in FIGS. 2A to 2B, and the slide bar 30 is retracted on the slide hole 20 by the elastic force of the spring S and the undercut of one side is processed. At the same time, as shown in FIGS. 3A to 3B, the first operating rod 12 is lifted and slides with the first operating hole 12a to retreat the slide core 10 to process the undercut on the other side.

이처럼, 단일의 슬라이드코어(10)를 이용하여 다중 언더컷의 처리가 가능함에 따라 금형의 구성이 간단하면서 고장발생률이 현저하게 감소되고, 또 금형제작에 따른 비용이 크게 절감되는 이점이 있다.As such, since multiple undercuts can be processed using a single slide core 10, the mold configuration is simple and the failure rate is remarkably reduced, and the cost according to the mold manufacturing is greatly reduced.
