본 고안은 아웃서트(out sert)용 몰드 금형에 있어서, 소재 장착시 소재면과 코어의 면접에 따른 과부하에 의한 코어의 손상이나 소재의 도장부분이 훼손되는 현상을 방지할 수 있게한 이중 면접 금형 장치에 관한 것이다.The present invention is a double mold for out sert mold to prevent damage to the core due to the overload caused by the interview between the material surface and the core or damage to the coating portion of the material during the mounting of the material Relates to a device.

종래의 아웃서트용 몰드금형은 제1도에 도시된 바와 같이 스프루 부시(1)와 로케트링(2) 이 고정되는 고정측설치판(3)과, 런너(4)과 취출하기 위한 런너 취출판(5)과, 고정측 코어(6)가 런너(4)를 취출하기 위한 런너취출판(5)과, 고정측 코어(6)가 고정되는 고정측 형판(7)과, 가동축 설치판(8)에 고정된 스페이서 블록(9)에 고정되는 반침판(10)과, 가동측 코어(12)가 고정되는 가동측 형판(11) 및 이젝트 플레이트(13)(14)에 고정되고 제품(15)을 취출시키기 위한 이젝트핀(16)등이 구비되고 고정측 형판(7)에는 코일스프링(17)으로 탄력 설치되는 지지구(18)가 설치된 구조로 되어 있다.As shown in FIG. 1, the conventional mold for the outsert has a fixed side mounting plate 3 to which the sprue bush 1 and the rocket ring 2 are fixed, and a runner for taking out with the runner 4. The publication 5, the runner taking-out plate 5 for the fixed side core 6 to take out the runner 4, the fixed side template 7 to which the fixed side core 6 is fixed, and a movable shaft mounting plate. The half needle plate 10 fixed to the spacer block 9 fixed to (8), the movable side template 11 and the eject plate 13, 14 to which the movable side core 12 is fixed are fixed to the product ( Eject pins 16 and the like for taking out 15) are provided, and the fixed side template 7 has a structure in which support members 18 are elastically installed with coil springs 17.

그리고. 아웃 서트용 제품으로 예시한 제품(15)은 제4도의 (a)(b)에 도시한 바와 같이, 전자레인지에 사용되는 턴테이블을 보인 것으로, 이는 소재원판(15')의 상, 하면이 페인팅되어 있고 그 중앙부에 아웃서트 되는 몰드 성형부(15a)를 갖는다.And. The product 15 exemplified as an out-supply product shows a turntable for use in a microwave oven, as shown in FIG. 4 (a) (b), which shows the upper and lower surfaces of the material original plate 15 '. It has a mold shaping part 15a which is provided and is centered in the center part.

다시 제1도를 참조하면. 종래의 금형은 금형이 열린 상태에서 지지구(18)를 이용하여 소재 원판(15')을 설치한 후 사출 성형기를 구동시키어 제1도와 같이 금형을 닫은 다음 노즐을 통하여 용융수지를 캐비티내에 투입시켜 아웃 서트 작업을 행한 뒤 응고후 제품(15)을 취출하게 된다.Referring back to Figure 1. In the conventional mold, after installing the raw material plate 15 'by using the supporter 18 in the mold open state, the injection molding machine is driven to close the mold as shown in FIG. 1, and then the molten resin is introduced into the cavity through the nozzle. After performing the out work, the product 15 is taken out after the solidification.

그러나, 이와 같은 종래의 금형은 제1도에 도시한, a, b, c부분에서 가동축과 고정측 금형이 공통적으로 면접을 이루어야 하기 때문에 3개소의 동시 면접을 위한 맞춤가공이 요구되어 금형제작이 까다롭게 될 뿐아니라 사출 성형기의 형 체결고압이 b,c부분에 직접 걸리게 되므로 코어(6)(12)의 b,c부위가 급격히 마모되어 손상되거나 제품(15)소재의 도장된 피복이 벗겨져서 불량의 원인이 되는 결함이 있었다.However, since the movable mold and the fixed side mold have to be commonly interviewed in the a, b, and c portions shown in FIG. 1, custom molds are required for three simultaneous interviews. Not only this is difficult, but the mold clamping pressure of the injection molding machine is directly applied to the b and c parts, so that the b and c parts of the cores 6 and 12 are rapidly worn and damaged or the painted coating of the product 15 is peeled off. There was a defect that caused the.

상기에서 면접은 가동측과 고정측 금형이 서로 맞닿는 상태나 그 부위를 가르키는 것임.In the above, the interview refers to the state where the movable side and the fixed side mold abut each other or the part thereof.

본 고안은 이러한 종래의 결함을 해소하기 위하여 안출한 것으로, 이를 첨부 도면에 의하여 상세히 실명하면 다음과 같다.The present invention has been devised to solve such a conventional defect, which will be described in detail by the accompanying drawings as follows.

제2도 및 제3도에 도시한 바와 같이, 가동측 코어(12)의 플랜지에 수개의 나사공(12a)을 형성하여 수개의 피스턴 로드(19)를 나사맞춤으로 조립하고 가동축 설치판(8)과 받침판(10) 사이에 수개의 단동실린더(20)를 설치함과 아울러 이젝트 플레이트(13)(14)에는 단동실린더(20)를 설치함과 아울러 이잭트 플레이트(13)(14)에는 단동실린더(20)의 외경보다 큰 구멍(21)을 뚫어 그 이젝트 플레이트(13)(14)가 자유로이 왕복 운동할 수있게 하며. 피스턴(22)의 좌측부. 즉 피스턴 로드(19)측에는 압축 코일스프링(23)을 장착하여 필요시에 피스턴로드(19)가 탄력적으로 이동할 수 있게 하였다.As shown in FIG. 2 and FIG. 3, several threaded holes 12a are formed in the flange of the movable core 12 to assemble several piston rods 19 by screwing, and the movable shaft mounting plate ( 8) and a plurality of single-acting cylinder 20 is installed between the support plate 10, and the single-acting cylinder 20 is installed in the eject plate (13), 14, and also in the eject plate (13) (14) A hole 21 larger than the outer diameter of the single-acting cylinder 20 is drilled so that the eject plates 13 and 14 can freely reciprocate. The left side of the piston 22. That is, the piston rod 19 is mounted on the compression coil spring 23 so that the piston rod 19 can move elastically when necessary.

이와같이 된 본 고안은 제3도와 같이 금형이 열린 상태에서 가동측 코어(12)는 받침판(10)에서 h간격만큼 후퇴할 수 있는 있는 여유를 갖고 있으며 i간격만큼 후퇴할 수 있는 여유를 갖고 있다.In the present invention as described above, the movable core 12 has a margin to retreat from the supporting plate 10 by h interval in the state in which the mold is opened, and a margin to retreat by i interval.

이러한 상태에서 사출성형기가 형체결을 위한 전진을 하면 제2도와 같이 상태가 되는데, 이때 실린더(20)의 반력은 형체결 압력보다 적으며 다만 사출압력에 의하여 가동측 코어(12)가 뒤로 밀려 c부위에 틈새가 생기지않을 정도로 압력을 조정해두지만 필요에 따라서는 압력을 높일수도 있다.In this state, when the injection molding machine moves forward for mold clamping, the state becomes as shown in FIG. 2, wherein the reaction force of the cylinder 20 is less than the clamping pressure, but the movable core 12 is pushed back by the injection pressure. Adjust the pressure so that there are no gaps in the area, but you can increase the pressure if necessary.

제2도와 같이 금형이 닫히게 되면 a부위가 서로 닿아서 사출 성형기의 형체결(금형닫힘) 동작이 완료되며 이때 코어(6)(12)의 b.c부위는 실린더(20)의 압력에 의하여 면접이 이루어지게 된다.As shown in FIG. 2, when the mold is closed, the a parts touch each other, thereby completing the mold clamping (molding) operation of the injection molding machine. At this time, the bc parts of the cores 6 and 12 are interviewed by the pressure of the cylinder 20. You lose.

금형이 완전히 닫힌 후에도 가동축코어(12)와 받침판(10)사이에는 틈새 f가 남게 되며 실린더(20)에도 피스턴(22)이 더 후퇴할 수 있는 여유 틈새(9)가 남아 있어 a, b, c부분의 동시 면접을 위한 맞춤 가공이 필요없게 된다.Even after the mold is completely closed, a gap f remains between the movable shaft core 12 and the support plate 10, and a clearance gap 9 for the piston 22 to retreat remains in the cylinder 20, so that a, b, There is no need for custom machining for the simultaneous interview of part c.

이상에서 설명한 바와 같이 본 고안 이중 면접 금형장치는,종래의 구조에서 문제점이던 a. b, c부위의 동시면접을 위한 맞춤작업을 할 필요가 없으인며. 과부하에 의한 코어(6)(12)의 면접부(b)(c)의 급격한 마모를 방지할 수 있게 되므로 코어(6)(12)의 수명을 연장할 수 있으며 면접부(b)(c)의 면접 불량으로 인하여 소재원판(15')의 도장된 부분이 손상됨이 없이 양호하게 보호되는 이점등이 있다.As described above, the subject innovation double interview mold apparatus is a. There is no need to do custom work for simultaneous interviews in b and c areas. It is possible to prevent the abrupt wear of the interview portion (b) (c) of the core (6) 12 due to overload can extend the life of the core (6) (12) and the interview portion (b) (c) Due to the poor interview, there is an advantage that the painted portion of the material disc 15 'is well protected without being damaged.
