본 고안은 사출금형에서 제품성형을 완료한 후 이를 추출시키기 위해 이용하는 사출금형의 성형제품 추출(EJECT)장치에 관한 것으로서, 특히 사출금형의 이동형판 내측에 이젝트핀을 시이소 동작 가능하게 두 개의 링크와 스프링으로 탄력 설치하고, 이중심부를 이젝트 구동플레이트를 통해 이젝트 피스톤 로드와 연결 설치하여 피스톤 로드의 전진시 중심부 이젝트핀이 전진하여 성형제품을 밀어주고, 반대로 피스톤 로드의 후진시에는 상, 하에 설치되는 이젝트핀이 전진하면서 성형제품을 완전히 금형에서 분리 추출시킬 수 있도록 한 사출금형의 성형제품 추출 장치에 관한 것이다.The present invention relates to an injection mold molded product extraction (EJECT) device that is used to extract the product after completing the molding in the injection mold, and in particular, two links and the ejector pin inside the movable die of the injection mold to enable the seesaw operation It is elastically installed with spring and connected with ejection piston rod through eject drive plate to eject ejection rod by moving the center eject pin when piston rod moves forward. The present invention relates to an apparatus for extracting a molded product of an injection mold that allows the eject pin to move forward to completely extract the molded product from the mold.

일반적으로 사출금형에 용융수지를 주입하여 제품성형을 완료한 후 이를 외부로 빼내기 위해서는 금형내부에 이젝트핀을 설치하여 이동형판과 고정형판의 형 분리시 이젝트핀이 작동하여 성형된 제품을 밀어 추출시켜 줄수 있게 되어 있다.In general, injecting molten resin into the injection mold to complete product molding and ejecting it to the outside, install eject pins inside the mold, and eject the molded product by operating the eject pin when separating the movable plate and the fixed plate. I can give it.

이와 같은 목적으로 이용되는 종래의 성형제품 추출장치를 보면 제3도에서 보는 바와 같이 사출금형(21)의 이동형판(22) 내측으로 성형판(23)에 이젝트 연결판(24)과 일체로 되게 다수의 이젝트핀(25)을 스프링(26)으로 탄력 설치하고 상기 이젝트 연결판(24)의 중심부를 구동플레이트(27)를 통해 이젝트 피스톤 로드(28)에 연결 설치하여 형 분리시 다수의 이젝트핀(25)이 동시에 전, 후진 동작하면서 성형제품(A)을 추출시킬 수 있게 구성되어 있다.In the conventional molded article extraction apparatus used for this purpose, as shown in FIG. 3, the injection plate 21 is integrated into the mold connecting plate 24 on the forming plate 23 inside the movable plate 22. A plurality of eject pins 25 are elastically installed with a spring 26 and the center of the eject connecting plate 24 is connected to the eject piston rod 28 through a driving plate 27 to install a plurality of eject pins. (25) is configured to be able to extract the molded product (A) while simultaneously moving forward and backward.

따라서 상기와 같은 종래의 추출 장치는 다수의 이젝트핀이 동시에 성형제품을 밀어 추출시키기 때문에 점도가 높은 성형품의 경우에는 추출시 이젝트핀에 붙는 형상이 나타나 제품의 추출작업이 정확하게 이루어지지 못하여 작업성이 저하되고 이에 따라 생산성이 저하되며, 또한 제품자체의 불량발생률이 높은 문제점이 있었다.Therefore, in the conventional extraction apparatus as described above, since a plurality of eject pins push out the molded product at the same time, the molded product having a high viscosity appears to adhere to the eject pin during extraction, and thus the extraction work of the product is not performed accurately. There was a problem that the lowering and thus the productivity is lowered, and the failure rate of the product itself is high.

본 고안은 상기와 같은 종래의 문제점을 보완하고져 사출금형의 이동형판 내측으로 성형판에 결합 설치되는 이젝트핀을 두 개의 링크로서 시이소 동작 가능하게 설치하여 중심의 이젝트핀과 상, 하의 이젝트핀이 형 분리시 순차적으로 작동되게 하여 용이하게 성형제품을 추출시킬 수 있게 한 것으로서, 이하 본 고안을 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention complements the above-mentioned problems and installs an ejector pin coupled to the molding plate inside the moving mold of the injection mold to enable the seesaw operation as two links so that the center eject pin and the upper and lower eject pins are formed. In order to be able to extract the molded product easily by sequentially operating when separated, described in detail by the accompanying drawings of the present invention as follows.

본 고안의 구성을 보면 제 1도에서 보는 바와 같이 통상적으로 이동형판(2)과 고정형판(3)으로 분리 구성되며, 이동형판(2) 내측으로 다수의 이젝트핀(4)(4')(4'')이 스프링(5)으로 탄력 설치되는 사출금형(1)에 있어서 상기 이동형판(2)에 블록(6)으로 연결 고정되는 이동축 성형판(7)내측에 고정보스(8)(8')를 일체로 돌출 형성하여 두 개의 링크(9)(9')를 회동 가능하게 핀(10)(10')으로 고정 설치하고, 이 양 링크(9)(9')의 중심부와 양측단에는 이젝트핀(4)(4')(4'')을 스프링(5)으로 고정 설치하며, 상기 양 링크(9)(9')의 중심부에는 연결로드(11)가 형성되어 이젝트 피스톤 링크(13)와 연결되는 이젝트 구동플레이트(12)에 접하여 지게 연결 구성된 것이다.In the construction of the present invention, as shown in FIG. 1, the movable plate 2 and the fixed plate 3 are generally separated, and the plurality of eject pins 4, 4 ′ (to the inside of the movable plate 2) ( In the injection mold (1) in which the 4 " is elastically installed by the spring (5), the high intelligence (8) (inside the movable shaft forming plate (7) fixed to the movable mold (2) is connected to the block (6). 8 ') are integrally formed to integrally fix the two links 9 and 9' with the pins 10 and 10 'so as to be rotatable, and the center and both sides of the two links 9 and 9' are fixed. Eject pins 4, 4 ′, 4 ″ are fixedly installed at the ends with springs 5, and connecting rods 11 are formed at the centers of both links 9, 9 ′, respectively, to eject piston links. It is configured to be in contact with the eject drive plate 12 is connected to the (13).

미 설명부호 (A)는 성형제품, (14)는 고정측 성형판 임.Unexplained symbol (A) is molded product and (14) is fixed side molded plate.

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

먼저 사출금형(1)의 고정측 성형판(14)과 이동축 성형판(7)사이로 용융수지를 주입하여 제품(A)성형을 완료한 후 성형된 상기 제품(A)을 추출시키기 위해 이동형판(2)을 고정형판(3)에서 분리시킨다음, 제2(a)도에서 보는 바와 같이 이동형판(2)의 내측에 설치되어 있는 이젝트 피스톤 로드(13)를 전진시키면 이와 연결된 구동플레이트(12)가 전진하면서 연결로드(11)를 밀어주게 된다. 이때 양링크(9)(9')는 고정보스(8)(8')의 핀(10)(10')을 중심으로 시이소 동작하면서 중심의 이젝트핀(4')만이 스프링(5)력을 축적하면서 전진하여 성형제품(A)을 밀어 금형과 분리시켜 주게 된다.First, the molten resin is injected between the fixed side mold plate 14 and the movable shaft mold plate 7 of the injection mold 1 to complete the molding of the product A, and then the movable mold to extract the molded product A. (2) is separated from the stationary plate 3, and then, as shown in FIG. 2 (a), when the eject piston rod 13 installed in the inside of the movable plate 2 is advanced, the drive plate 12 connected thereto is connected. ) Pushes the connecting rod 11 as it moves forward. At this time, both links (9) and (9 ') are operated by the seesaw around the pins (10) and (10') of the high information (8) and (8 '), and only the center eject pin (4') applies the spring (5) force. As it accumulates, it moves forward and separates the molded product A from the mold.

이와 같이 성형제품(A)을 먼저 이동형판(2)의 이동측 성형판(7)에서 분리시킨 상태에서 반대로 이젝트 피스톤 로드(13)가 후진을 하게되면 중심의 이젝트핀(4')에 설치된 스프링(5)의 축적된 반발력으로 제2(b)도에서 보는 바와 같이 중심의 이젝트핀(4')은 후진하게되고 이와 동시에 양 링크(9)(9')가 고정보스(8)(8')의 핀(10)(10')을 중심으로 시이소 동작하면서 양 링크(9)(9')의 양단에 연결된 상, 하 이젝트핀(4)(4'')이 전진하면서 중심의 이젝트핀(4')이 밀어 분리시켜 놓은 성형제품(A)의 상, 하단을 밀어 완전히 추출시킬 수 있게 되는 것이다.As such, when the ejected piston rod 13 reverses in a state where the molded product A is first separated from the moving side forming plate 7 of the moving die 2, the spring is installed on the center eject pin 4 ′. With the accumulated repulsive force of (5), as shown in FIG. 2 (b), the center eject pin 4 'is reversed, and at the same time, both links 9, 9' are connected to high information 8, 8 '. The upper and lower eject pins 4 and 4 '' connected to both ends of both links 9 and 9 'move forward while the seesaw operates about the pins 10 and 10' of the 4 ') is to push the upper and lower parts of the molded product (A) separated by pushing to be completely extracted.

이와 같은 동작이 이루어질 때 이젝트 피스톤 로드의 전, 후진 동작에 따라 양 링크가 고정보스의 핀을 중심으로 시이소 동작하면서 중심 이젝트핀과 상, 하 이젝트핀을 순차적으로 전, 후진시켜 성형제품을 완전히 분리 추출시킬 수 있게 된다. 그러므로 정도가 높은 성형제품이라 할지라도 이젝트핀에 달라 붙는 현상이 나타나지 않아 용이하게 성형제품을 추출시킬 수 있어 작업능률과 생산성을 극대화 시킬 수 있고, 또한 성형제품의 불량 발생률을 최소로 줄여 줄수 있는 효과도 얻고자 한 것이다.When such a movement is made, both links move on the high-information pin according to the forward and backward movement of the eject piston rod, and the main eject pin and the upper and lower eject pins are sequentially moved forward and backward to completely separate the molded product. Can be extracted. Therefore, even high precision molded products do not stick to the eject pins, making it easy to extract molded products, maximizing work efficiency and productivity, and minimizing the defective rate of molded products. I would also like to get.
