본 고안은 사출금형의 구조에 관한 것으로서, 특히 슬라이딩코어의 작동행정이 긴 경사핀이 슬라이딩코어와 밀핀의 간섭됨을 방지할 수 있도록한 것이다.The present invention relates to the structure of an injection mold, and in particular, to allow the operation of the sliding core to prevent the long inclined pins from interfering with the sliding core and the mill pin.

종래의 사출 금형의 구조는 제5도에서 보는 바와같이 금형이 오픈상태에서 닫히면 고정측 형판(51)에 고정된 경사핀(KP)(16)이 가동측형판(52)상측의 슬라이드코어(SC)(15)를 화살표방향으로 이동시키고 리턴핀(RETURN PIN)이 고정측형판(51)의 하측면 즉 D면에 면접되면, 리턴핀에 의해서 이젝트플레이트 상.하(54)(54')가 원위치로 돌아간다.As shown in FIG. 5, when the mold is closed in the open state, the conventional injection mold has a slide core (SC) 16 on the movable side plate 52 having the inclined pin (KP) 16 fixed to the fixed side plate 51. (15) in the direction of the arrow and the return pin is interviewed on the lower side of the fixed side plate 51, that is, the D surface, the eject plate up and down (54, 54 ') by the return pin Return to home position.

이때 상기 슬라이드코어(SC)(15)는 이젝트플레이트상,하(54)(54')가 완전히 후퇴하기도 전에 작동됨으로서 슬라이드코어(SC)(15) 하측 모서리부와 밀판(MP)의 상측 모서리부의 충돌로 인한 파손의 우려가 있는 문제점이 야기되었다.At this time, the slide core (SC) 15 is operated before the upper and lower (54, 54 ') of the eject plate is fully retracted, so that the lower edge of the slide core (SC) 15 and the upper edge of the sealing plate (MP) are operated. There is a problem that there is a risk of damage due to collision.

본 고안은 상기한 종래의 문제점을 해결하기 위하여 안출된 것으로서 본 고안의 목적으로는 슬라이드코어와 밀핀의 간섭됨을 방지하여 파손됨을 방지할 수 있도록한 것이 특징이다.The present invention is devised to solve the above-mentioned problems, and the object of the present invention is to prevent the interference between the slide core and the pin.

상기의 목적을 달성할 수 있는 본 고안을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.When the present invention to achieve the above object will be described in detail by the accompanying drawings as follows.

고정측형판(1)과 가동측형판(2)에 이젝트플레이상.하(4)(4')로 구성되는 사출금형에 있어서 상기 고정측형판(1) 중앙에는 조속되돌림바(3)를 소켓트볼트(11)로 고정한다.In the injection mold consisting of the eject plate upper and lower (4) and (4 ') on the stationary side plate (1) and the movable side plate (2), a fastening bar (3) is placed at the center of the stationary side plate (1). Secure with bolts (11).

이때 조속되돌림바(3)의 일지점에는 걸림요홈(3a)을 형성하였다.At this time, at one point of the quick return bar (3) was formed a locking groove (3a).

그리고 상기 가동측형판(2)과 이젝트플레이트상.하(4)(4')전면에는 상단고리지지대(5)를 설치하되 상단고리지지대(5)의 하측부에는 이젝트플레이트하(4')와 소켓볼트(12)로 고정하고 상단고리지지대(5)의 양측에는 가이드요홈(6)(6')을 형성한후 상기 가이드요홈(6)(6')과 일치되는 위치인 가동측형판(2)에 가이드링(10)(10')을 소켓볼트(13)로 고정설치한다.The upper side of the movable side plate (2) and the upper and lower ejection plate (4) (4 ') is provided with an upper plate support (5), the lower portion of the upper plate (5) eject plate (4') and Fixing with a socket bolt (12) and forming guide grooves (6) (6 ') on both sides of the upper retaining zone (5) and then movable side plate (2) which is a position coinciding with the guide grooves (6) (6'). Fix the guide rings (10, 10 ') to the socket bolts (13).

한편 상단고리지지대(5)의 중앙상측 즉, 상기 조속되돌림바(3)의 슬라이딩 위치에 상단고리(7)를 고정설치하되 이 상단고리(7)의 양측에는 스프링(8)과 강구(9)를 지지설치하여 구성된 것이다.On the other hand, the upper ring (7) is fixed to the upper center of the upper ridge (5), that is, the sliding position of the speed bar (3), the spring (8) and the steel ball (9) on both sides of the upper ring (7) It is configured to support the installation.

이와같이 구성된 본 고안은 사출금형을 가동시키면 제3도 및 제4도에서와 같이 고정측형판(1)과 가동측형판(2)사이가 벌어지면서 열린다.When the injection mold is operated, the present invention configured as described above opens as the gap between the stationary side plate 1 and the movable side plate 2 opens as shown in FIGS. 3 and 4.

그리고 사출성형된 제품을 취출하기 위하여 사출가로 이젝트플레이트(4)(4')를 "A"방향으로 이동시키면 상단고리지지대(5)는 가이드홈(6)(6')에 의하여 가이드링(10)(10')의 외경을 따라 이젝트플레이상.하(4)(4')와 함께 이동하게되면 제품을 금형에서 인출한후 벌어진 금형을 닫는다.Then, in order to take out the injection-molded product, when the ejection plate 4 and 4 'are moved in the direction of "A", the upper ridge 5 is guided by the guide grooves 6 and 6'. When move along with the upper and lower ejection play (4) (4 ') along the outer diameter of 10'), the product is removed from the mold and the opened mold is closed.

이때 고정측형판(1)에 소켓볼트(11)로 고정한 조속되돌림바(3)는 작동시키기전에 상단 고리지지대(5)의 상단고리(7)에 설치된 강구(9)에 충돌하게 되는데 이때 강구(9)를 지지하고 있는 스프링(8)의 스프링력에 의하여 강구(9)는 후퇴하지않은채 상단고리(7)와 연결되어 있는 상단고리지지대(5)에 의해 이젝트플레이트상,하(4)(4')가 이동하면서 제2도에서와 같이 "B"지점에 위치하면 강구(9)를 지지하던 스프링(8)이 압축되면서 조속되돌림바(3)를 잡고있게 된다.At this time, the fastening bar (3) fixed to the fixed side plate (1) with the socket bolt (11) is to collide with the steel ball (9) installed on the upper ring (7) of the upper ring support (5) before operating the steel ball ( 9) The steel plate 9 is supported by the spring force of the spring 8 supporting the upper and lower ejection plates 4 and 4 by the upper ridge 5 connected to the upper ring 7 without retreating. When 4 ') moves and is positioned at the "B" point as shown in FIG. 2, the spring 8 supporting the steel ball 9 is compressed to hold the fastening bar 3.

이상 설명한 바와같이 고정측형판에 조속되돌림바를 고정설치하여 이 조속되돌림바를 상단고리의 스프링지지에 의한 강구에 의하여 잡고있게되므로 이젝트플레이트가 완전히 후퇴하기 전에는 슬라이드코어가 작동하지 않게되므로서 슬라이드코어와 밀핀의 충돌로 인한 파손의 우려가 전혀없는 유용한 고안이다.As described above, the fastening bar is fixedly installed on the fixed side plate to hold the fastening bar by the steel ball by the spring support of the upper ring, so that the slide core is not operated until the eject plate is fully retracted. It is a useful design with no fear of breakage due to crashing.
