본 고안은 사출금형의 런너(Runner)자동 꺼냄장치에 관한 것으로, 특히 금형 작동에 따라 런너가 제품에서 자동적으로 절단되어 꺼내질 수 있도록 한것이다.The present invention relates to a runner automatic ejection device of an injection mold, and in particular, to enable the runner to be automatically cut out of the product according to the mold operation.

종래에는 제품 성형시 제품과 함께 성형되는 런너를 제품에서 분리하기 위해 여러가지 형상의 언더컷 구조를 이용하여 제품에서 런너를 절단한 후 절단된 런너를 손으로 집어내거나 또는 사이드게이트(Side Gate)를 이용하여 제품과 런너를 함께 꺼낸후 손이나 별도의 컷터에 의해 런너를 절단하였다.Conventionally, in order to separate the runner formed with the product from the product during molding, by using the undercut structure of various shapes, the runner is cut from the product and the cut runner is picked up by hand or by using a side gate. After the product and the runner were taken out together, the runner was cut by a hand or a separate cutter.

그러나 이러한 종래의 장치들은 모두 제품에서 런너를 절단하는 작업과 런너를 꺼내는 작업이 별도의 공정으로 이루어지고, 또 이들 작업이 대부분 수동작업에 의해 행하여 지기 때문에 작업시간이 많이 소요되고 따라서 생산성의 저하를 초래하게 되는 문제점이 있었다.However, all of these conventional devices cut the runner from the product and take out the runner as a separate process, and since these operations are mostly performed by manual work, it takes a lot of work time and thus decreases productivity. There was a problem brought about.

본 고안은 종래의 장치들이 지닌 이와 같은 문제점을 해소하기 위한 것으로, 금형 작동시 런너가 동시에 절단되어 꺼내질 수 있는 개선된 구조의 장치를 제공코저 한것인바, 이를 첨부된 도면에 의해 그 구조를 더욱 상세히 설명하면 다음과 같다.The present invention is to solve the problems of the conventional devices, to provide a device of an improved structure that the runner can be cut and taken out at the same time during the operation of the mold, the structure by the accompanying drawings More detailed description is as follows.

첨부도면 제1도는 본 고안 장치를 가진 사출금형의 일부 단면도로서 고정측 형판(1)과 가동측형판(2) 사이에 슬라이드코어(3)가 설치되고 있고 슬라이드코어(3) 내부에는 코어핀(4)이 스프링(5)에 의해 탄력설치되어 있으며 코어핀(4)의 하단 일측에는 일정각도 만큼 경사지게 절단된 경사면(4a)이 형성되어 있다.1 is a partial cross-sectional view of an injection mold having a device of the present invention, in which a slide core 3 is installed between a fixed side template 1 and a movable side plate 2 and a core pin (inside the slide core 3). 4) is elastically installed by the spring (5) and the inclined surface (4a) is formed to be inclined by a predetermined angle on one side of the lower end of the core pin (4).

고정측 형판(1)의 일측에 절곡된 형상의 링크(6)가 고정되어 있고 이 링크(6)에는 제2도와 같이 세로방향으로 길게 형성된 작동폼(7)이 뚫려 있으며 작동홈(7)에는 링크핀(8)이 끼워짐과 함께 그 링크핀(8)이 슬라이드코어(3)에 결합되어 있다.A bent link 6 is fixed to one side of the stationary side template 1, and the link 6 is formed with an operating form 7 elongated in the longitudinal direction as shown in FIG. The link pin 8 is fitted and the link pin 8 is coupled to the slide core 3.

가동측 형판(2)의 상방에는 코이핀(4)하단에 형성된 경사면(4a)과 동일한 경사면을 가진 경사편(9)이 고정되어 있고 슬라이드코어(3)의 전, 후방에는 대향된 한쌍의 가이드편(10)이 설치되어 있어 가동측형판(2)의 작동에 따라 슬라이드코어(3)가 수평적으로 진퇴할 수 있도록 되어 있다.On the upper side of the movable side template 2, the inclined pieces 9 having the same inclined surface as the inclined surface 4a formed at the bottom of the coffin pin 4 are fixed, and a pair of guides opposed to the front and rear of the slide core 3 are opposed. The piece 10 is provided so that the slide core 3 can retract horizontally in accordance with the operation of the movable side plate 2.

도면중 설명되지 않은 부호 11은 이젝트 핀, 12는 제품, 13은 런너이다.In the figure, reference numeral 11, which is not described, is an eject pin, 12 is a product, and 13 is a runner.

이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

먼저 고정측형판(1)과 가동측형판(2)에 의해 제품(12)이 성형된 상태에서는 제1도와 같이 링크(6)의 작동홈(7)에 끼워져 슬라이드코어(3)와 결합되어 있는 링크핀(8)이 절곡된 형상으로 된 링크(6)의 상방부분에 위치하게 되고 이에 따라 슬라이드코어(3)는 가동측형판(2)의 일측벽과 밀착된 상태에 있게 된다.First, in the state in which the product 12 is molded by the stationary side plate 1 and the movable side plate 2, the product 12 is fitted into the operating groove 7 of the link 6 and coupled with the slide core 3 as shown in FIG. 1. The link pin 8 is located in the upper portion of the bent link 6 so that the slide core 3 is in close contact with one side wall of the movable side plate 2.

이러한 상태에서 성형된 제품을 꺼내기 위해 가동측형판(2)을 열면 슬라이드코어(3)가 링크(6)방향으로 이동함과 동시에 런너(13)가 제품(12)에서 자동적으로 절단되어 꺼내지는데, 가동측 형판(2)이 열리면 제3도와 같이 슬라이드코어(3)와 결합된 링크핀(8)이 작동홈(7)을 따라 하방으로 이동하게 되고 링크핀(8)이 하방으로 이동하면 슬라이드코어(3)가 한쌍의 가이드 핀(10)을 따라 링크(6)방향으로 이동하려는 힘을 받게 되어 그 힘에 의해 런너(13)는 제품(12)에서 절단되며, 런너(13)가 절단된 후에는 슬라이드코어(3)내에 설치된 코어핀(4)하단의 경사면(4a)이 경사면(9)을 따라 스프링(5)을 압축하면서 상승하게 되므로 절단된 런너(13)가 자동적으로 금형에서 꺼내지는 것이다.When the movable side plate 2 is opened to take out the molded product in such a state, the slide core 3 moves in the link 6 direction and the runner 13 is automatically cut out of the product 12 and taken out. When the movable side template 2 is opened, as shown in FIG. 3, the link pin 8 coupled with the slide core 3 moves downward along the operation groove 7, and when the link pin 8 moves downward, the slide core (3) is subjected to a force to move in the direction of the link (6) along the pair of guide pins (10) by which the runner (13) is cut from the product (12), after the runner (13) is cut Since the inclined surface 4a at the bottom of the core pin 4 installed in the slide core 3 is raised while compressing the spring 5 along the inclined surface 9, the cut runner 13 is automatically taken out of the mold. .

또, 이렇게 런너(13)가 절단되어 꺼내진 후 가동측형판(2)을 닫으면 링크핀(8)이 링크(6)의 작동홈(7)을 따라 상방으로 이동하고 슬라이드코어(3)는 가이드핀(10)을 따라 이동하여 가동측형판(2)의 일측벽에 밀착되는 제1도와 같은 상태로 환원되므로 다시 제품을 성형할 수 있게 된다.When the runner 13 is cut and taken out in this way and the movable side plate 2 is closed, the link pin 8 moves upward along the operation groove 7 of the link 6 and the slide core 3 is guided. Moving along the pin 10 is reduced to the same state as in FIG.

이상에서와 같이 본 고안은 가동측 형판(2)의 열림과 닫힘에 따라 슬라이드코어(3)가 이동하면서 자동적으로 런너를 제품에서 절단한 후 배출하도록 되어 있으므로 수동작업에 의해 런너를 절단하고 꺼내던 종래의 장치의 비해 작업공정이 간소화되고 따라서 작업능률을 향상시킬 수 있는 효과가 있다.As described above, according to the present invention, since the slide core 3 moves and the runner is automatically cut from the product according to the opening and closing of the movable side template 2, the runner is cut and taken out by manual operation. Compared with the conventional apparatus, the work process is simplified, and thus, the work efficiency can be improved.
