본 고안은 사출금형의 3단금형에서 런너취출판의 변형을 방지하기 위하여 상,하형판이 다른 부위 즉, 상형판과 런너취출판 또는 상형착설판과 런너취출판의 사이보다 먼저 벌어져서 분리되지 않도록 구성한 사출금형의 형판개폐용 클램프장치에 관한 것으로, 외측면에 요홈부를 가진 탄성편으로 구성된 "U"자형 링크장치와 탕성편의 요홈부에 결착되도록 내면을 형성시킨 클램프체로서 상,하형판을 결합시켜 주므로서 런너취출판과 상형판 및 상형착설판의 사이가 벌어져서 분리된 후에 상,하형판의 사이가 벌어져서 분리되도록 구성한 것이다.In order to prevent deformation of the runner take-out plate in the three-stage mold of the injection mold, the present invention is configured such that the upper and lower dies are not separated by being separated before other parts, that is, between the upper plate and the runner take-out plate or the upper mounting plate and the runner take-out plate. The clamping device for the mold opening and closing of the injection mold, the "U" shaped link device consisting of an elastic piece having a groove on the outer surface and a clamp body formed by forming the inner surface to be bonded to the groove portion of the molten piece to combine the upper and lower plate The gap between the runner take-out plate, the upper plate and the upper plate mounting plate is separated by separating the upper and lower plate plates.

종래에도 사출금형의 형판이 벌어져서 분리되는 순서를 조절시켜 주기 위하여 여러종류의 장치드링 사용되었으나, 대부분이 스프링을 주된 부품으로 사용하였기 때문에 부품수가 많아지고 구조가 복잡해지므로서 그에 따른 장치의 부피가 커져서 많은 공간을 차지하였던 것이다.Conventionally, various types of device rings have been used to control the order in which the injection mold template is opened and separated. However, since most of the springs are used as the main parts, the number of parts increases and the structure becomes complicated, thereby increasing the volume of the device. It took up a lot of space.

따라서, 이러한 장치를 사용하여 사출제품을 양산시에 주된 부품인 스프링의 작동상태가 불확실한 경우가 빈번하게 발생하므로서 상,하형판의 클램핑 상태가 불완전하게 되어 제품의 불량 및 장치의 파손율이 많았던 것이다.Therefore, when the mass production of the injection product using such a device frequently occurs the operating state of the spring, which is the main component, the clamping state of the upper and lower plate is incomplete, so that the defect of the product and the failure rate of the device were many.

또한, 최근에는 실용신안공고 제 85-285호 "사출금형의 형판 개폐용 캠장치"와 같이 고정측형판에 부착되어 있는 한쌍의 고정지지부와 고정측착설판에 부착되어 상기 한쌍의 고정지지부 사이를 지나 아래쪽으로 연장되며, 머리부에는 두개의 경사캠면이 형성된 캠과 스페이스 블럭에 부착된 고정판에 힌지핀으로 결합되어 머리부에는 두개의 경사캠면을 가지며, 상기 고정지지부의 상측면과 평면접촉으로 맞물리도록 형성되며 하단에는 스프링을 제재시킨으로 구성된 것이 안출되었으나, 이 역시 스프링을 주된 부품으로 사용하므로서 장기간 사용시에 불완전 작동상태의 경우가 발생하였을 뿐만 아니라, 스프링이 파손되는 등의 문제점이 있었던 것이다.In addition, recently, a pair of fixed support parts attached to a fixed side mold plate and a fixed side mounting plate, such as Utility Model Publication No. 85-285, "Injection mold opening and closing cam device", is provided between the pair of fixed support parts. It extends downwardly and is coupled to the head by two hinge cams to the fixed plate attached to the cam and the cam formed with two inclined cam surfaces, the head has two inclined cam surfaces, and meshes in planar contact with the upper surface of the fixed support. It is formed so as to be formed to be lowered to the lower end of the spring is composed, but this is also used as a main part of the spring, as well as the case of incomplete operating state in the long-term use, there was a problem such that the spring is broken.

상, 하형판(1) (2) 및 런너취출판(3)과 상형착설판(4) 및 스페이스블럭(5)으로 구성되는 통상의 사출금형의 형판개폐용 클램프장치를 구성함에 있어서, 하형판(2)의 일측면에는 외주면에 요홈부(8)를 가진 탄성편(7)으로 구성된 "U"자형 링크장치(6)를 착설하고, 상형판(1)의 일측면에는 링크장치(6)의 탄성편(7)과 결착되도록 내면부에 경사면(10) (11)을 형성시킨 클램프체(9)를 착설하여서 링크장치(6)의 탄성편(7)과 클램프체(9)의 경사면(10) (11)에 의하여 상, 하형판(1) (2)을 결합하거나 분리하도록 구성함을 특징으로 하는 사출금형의 형판 개폐용 클램프장치이다.In forming a clamping apparatus for mold opening and closing of a normal injection mold, which is composed of upper and lower mold plates (1) and (2) and runner take-out plate (3), upper mold mounting plate (4), and space block (5), On one side of (2) is installed a "U" shaped link device (6) consisting of an elastic piece (7) having a recessed portion (8) on the outer peripheral surface, the linkage device (6) on one side of the upper plate (1) The inclined surface (10) and the inclined surface (10) (11) formed in the inner surface portion to be engaged with the elastic piece (7) of the elastic member (7) of the linkage device (6) and the inclined surface of the clamp body (9) 10) The mold opening and closing clamp device of the injection mold, characterized in that (11) by the upper and lower die plate (1) (2) configured to combine or separate.

첨부도면중 미설명 부호 12는 인장봉, 13는 삼단봉, 14는 부시, 15는 런너 칼퀴핀, 16은 케이트(gate), 17은 제품을 각각 나타낸다.In the accompanying drawings, reference numeral 12 denotes a tension rod, 13 a three-stage rod, 14 a bush, 15 a runner calquipin, 16 a gate, and 17 a product.

이와같은 본 고안의 작동상태를 첨부도면에 의하여 구체적으로 설명하면 다음과 같다.If described in detail by the accompanying drawings the operating state of the present invention as follows.

즉, 첨부도면은 제1도에 도시된 바와같이 상형판(1)의 일측면에는 클램프체(9)가 고정착설되고 하형판(2)의 일측면에는 링크장치(6)가 고정착설되어서 링크장치(6)와 클램프체(9)에 의하여 상,하형판(1) (2)이 결합된 상태에서 금형이 벌어져서 열리기 시작하면, 첨부도면 제2도에 도시된 바와같이 삼단봉(13)이 상승하면서 상형판(1)과 런너취출판(3)의 사이를 벌어져 분리되는 것이고 이때, 상,하형판(1) (2)은 링크장치(6)와 클램프체(9)에 의하여 결합된 상태로 있게 되는 것이다.That is, as shown in FIG. 1, the clamp body 9 is fixedly mounted on one side of the upper plate 1, and the linkage 6 is fixedly mounted on one side of the lower plate 2, and thus the link is attached. When the mold is opened and opened in the state where the upper and lower mold plates 1 and 2 are coupled by the device 6 and the clamp body 9, the three-stage rod 13 is raised as shown in FIG. While separating between the upper plate (1) and the runner take-off plate (3) is separated, the upper and lower plate (1) (2) is coupled by the link device 6 and the clamp body (9) Will be.

금형은 계속 열리면서 첨부도면 제3도에 도시된 바와같이 삼단봉(13)이 더이상 상승하지 못함에 따라서 인장봉(12)의 상승으로 상형착설판(4)만 계속 상승하여서 런너취출판(3)과의 사이가 벌어져서 분리되는 것이고 이때, 상,하형판(1) (2)은 계속 결합상태를 유지하게 되는 것이다.As the mold continues to open, as shown in FIG. 3 of the accompanying drawings, as the three-stage rod 13 is no longer raised, only the upper mounting plate 4 is continuously raised due to the rise of the tension rod 12 so that the runner take-out plate 3 and The gap between the separation will be separated, at this time, the upper and lower plate (1) (2) will continue to maintain a coupled state.

이러한 상태에서도 금형은 계속열리면서 이때의 금형이 열리는 힘이 상형판(1)과 하형판(2)의 결합상태를 유지하고 있는 링크장치(6)와 클램프체(9)의 결합력보다 크게 되어서 상형판(1)과 하형판(2)의 사이가 첨부도면 제4도에 도시된 바와같이 벌어져서 분리되는데 이때, 상형판(1)에 착설된 클램프(9)의 내면부에 형성된 경사면(10)이 하형판(2)에 착설된 "U"자형 링크장치(6)의 탄성력(7)의 외주면에 형성된 요홈부(8)의 상측경사면(8-1)을 밀면서 탄성력(7)을 오므라들게 하므로서 클램프체(9)가 링크장치(6)에서 해탈되는 것이다.Even in this state, the mold continues to open, and the force at which the mold is opened is greater than the coupling force between the link device 6 and the clamping body 9 which maintains the coupling state of the upper plate 1 and the lower plate 2. The space between (1) and the lower die plate (2) is separated by opening as shown in FIG. 4, wherein the inclined surface (10) formed on the inner surface portion of the clamp (9) mounted on the upper die plate (1) The clamping body is made to retract the elastic force 7 while pushing the upper inclined surface 8-1 of the recess 8 formed on the outer circumferential surface of the elastic force 7 of the " U " link device 6 mounted on the plate 2; (9) is released from the linkage device (6).

상기와 같이 작동되어 열린 상태에서 다시 금형이 닫힐 때는 상형판(1)이 하강하면서 상형판(1)에 착설된 클램프체(9)의 내면부에 형성된 경사면(11)이 하형판(2)에 착설된 링크장치(6)의 탄성편(7)의 상측경사면(7-1)을 밀면서 탄성편(7)을 오므라들게 하므로서 클램프체(9)가 링크장치(6)와 결합되게 되는 것이다.When the mold is closed again in the opened and operated state as described above, the inclined surface 11 formed on the inner surface portion of the clamp body 9 mounted on the upper mold plate 1 while the upper mold plate 1 is lowered to the lower mold plate 2. The clamping body 9 is coupled to the linking device 6 by pushing the upper inclined surface 7-1 of the elastic piece 7 of the installed linking device 6 to retract the elastic piece 7.

본 고안의 링크장치(6)와 클램프체(9)가 결합착설되거나 해탈분리되는 것은 링크장치(6)의 탄성편(7)이 갖는 탄성력 즉, 일반적인 철등의 금속이 갖는 탄성한계점이 넘지 않는 일정한 힘의 범위내에서 변형없이 발생하는 탄성력을 이용한 것이다.When the link device 6 and the clamping body 9 of the present invention are attached to or detached from each other, the elastic force of the elastic piece 7 of the link device 6, that is, the constant limit not exceeding the elastic limit point of a metal such as iron, is constant. It uses elastic force that occurs without deformation within the force range.

상기과 같은 본 고안은 종래와 같이 스프링등의 부품을 사용하지 않고 철등의 금속재로서 간단한 구조로 구성하므로서 고장의 염려가 전혀 없어 불확실한 작동이 발생하지 않을 뿐만 아니라, "U"자형 링크장치(6)의 탄성편(7)의 사이에 고무 또는 우레탄등의 물질을 삽입 착설하여서 링크장치(6)의 탄성편(7)이 갖는 탄성력을 조절하여 줄 수도 있으므로서 별도의 전기 스위치나 타이밍장치에 의한 미세한 조정이나 공기에 의한 콘트롤이 필요없는 것이다.As described above, the present invention does not use any components such as springs, and thus has a simple structure as a metal material such as iron, so that there is no fear of failure, and thus, the operation of the U-shaped link device 6 is not generated. The elastic force of the elastic piece 7 of the linking device 6 can be adjusted by inserting and installing a rubber or urethane material between the elastic pieces 7 so as to make fine adjustment by a separate electric switch or timing device. No air control is necessary.

또한, 본 고안의 링크장치나 클램프체는 금형의 크기에 큰 구애됨이 없이 폭넓게 착설사용할 수 있으므로서, 지금까지 사용되어 온 종래의 어떠한 장치보다도 폭넓소 광범위하게 사용할 수 있는 매우 실용적이며, 유용한 고안인 것이다.In addition, the linkage or clamp body of the present invention can be used in a wide range of installations without any particular concern about the size of the mold, and is a very practical and useful design that can be used in a wider range than any conventional devices used up to now. It is

본 고안은 사출금형이 형판개폐를 필요한 순서대로 정확하게 작동시켜 주므로서 확실한 작동상태를 보장받을 수 있으며, 간단한 구조로서 생산성이 있어서 대량생산되어 저렴한 가격으로 공급되어 유용하게 사용할 수 있는 것이다.The present invention can ensure a reliable operating state by the injection mold to operate the mold opening and closing exactly in the required order, it is a simple structure that can be useful because it is productive and mass-produced and supplied at a low price.
