Description

사출금형의 슬라이드 코어를 이용한 2단취출 장치Two-stage extraction device using slide mold of injection mold

제1도는 본 고안의 조립상태도.1 is an assembled state of the present invention.

제2도 및 제3도는 본 고안 작동 상태도.2 and 3 is a working state of the present invention.

본 고안은 사출금형 작업에서 2단 취출을 요하는 성형품을 얻기 위하여 경사핀과 슬라이드 코어와 이젝타봉에 의해서 작동시켜 그 가공 공정 공수를 줄이며 금형중량을 가볍게 한 것이다.The present invention is operated by the inclined pin, the slide core and the ejector rod in order to obtain a molded article requiring two-stage ejection in the injection mold operation to reduce the number of processing process and lighten the mold weight.

종래의 2단 취출을 필요로 하는 성형품을 가공하는 금형은 부품의 수가 많고, 이 부품을 조립하고 그 가공에도 시간이 많이 소요되며 이젝타판 및 이젝팅 거리를 조정해주기 위해 이젝타봉을 따로히 설치함으로 금형의 무게가 무거워지고 스테이스와 블록이 커지는 결과 금형높이가 또한 커지는 문제점이 있다.The mold for processing a molded article that requires a conventional two-stage ejection has a large number of parts, and it takes a long time to assemble and process the parts, and separately installs ejector rods to adjust ejector plate and ejecting distance. The weight of the mold becomes heavy and the mold height also increases as a result of the increase in the state of the station and the block.

이와 같은 문제점을 해결하기 위하여 안출한 것으로서 본 고안은 복잡한 구성을탈피하고 중량도 줄이고 그 조립 및 작동이 신속히 된 간단한 금형으로 첨부도면에 의하여 그 구성 및 작용효과를 구체적으로 설명하면 다음과 같다.The present invention as devised to solve such a problem is described in detail the configuration and the effect by the accompanying drawings as a simple mold to escape the complex configuration, reduce the weight and assembly and operation is as follows.

본 고안은 고정측 형판(1)하부 중심에 제품의 형상이 금형 중심선과 일치되는 가동측형판(2)의 스트리퍼편(10)이 연결된 이젝터봉(14)을 와서(12)와 너트(13)사이에 스프링(11)으로 받침판(3) 양요홈(3a)내에 조립하고 이 받침판(3)의 양 경사구멍(3b)에다 경사핀(8) 상부를 체착 조립하고 그 하부는 이젝터판(5)에 고착된 슬라이드 코어(9) 경사구멍(9a)과 조립하며, 받침판(3)은 가동측 설치판(7) 양지주인 스페이스 블록(4)으로 지지되어 있고, 슬라이드 코어(9)평면부와 경사면부를 형성하여 취출장치의 밀핀(15)으로 이젝터판(5)(6)이 상승할때 이젝터봉(14) 하부단부가 이 평면부A 점에서 경사면부 B점으로 이동되어져 성형풀이 빠지게 되는 구성인 것이다.According to the present invention, the ejector rod 14 connected to the stripper piece 10 of the movable side plate 2 in which the shape of the product coincides with the mold center line at the center of the lower side of the stationary side plate 1 comes with 12 and the nut 13. Spring 11 is assembled into the support plate 3 in the recess groove 3a, and the upper part of the inclined pin 8 is fixedly assembled to both inclined holes 3b of the support plate 3, and the lower part of the ejector plate 5 is It is assembled with the slide core 9 inclined hole 9a fixed to the support plate 3, and the support plate 3 is supported by the space block 4 which is a supporter of the movable side mounting plate 7, and the slide core 9 plane part and the inclined surface The lower end of the ejector rod 14 is moved from this flat portion A point to the inclined surface portion B point when the ejector plate 5, 6 is raised by the mil pin 15 of the take-out device, so that the molding pool is removed. will be.

본 고안 작동 상태를 첨부도면 제2도에서 설명하면 우선 미도시된 사출기에 본고안 금형을 조립시킨후 이 금형이 열릴때 고정축 형판(1)과 가동측 형판(2)이 먼저 열리고 나서 취출장치의 밀핀(15)에 의해서 이젝터판(5)(6)이 위로 상승하므로서 제3도와같이 일정한 순간인 즉, 슬라이드 코어(9)의 평면부 A점 위까지는 똑같이 스트리퍼편(10)과 슬라이드 코어(9)가 상승하여 코어부위에서 성형품인 제품이 빠져 나온다.Referring to FIG. 2 of the present invention, the present invention is assembled with an unshown injection molding machine, and when the mold is opened, the fixed shaft template 1 and the movable side template 2 are opened first, and then the take-out device is opened. As the ejector plate 5, 6 rises by the pin 15 of the pin 10, the stripper piece 10 and the slide core ( 9) rises and the molded product comes out from the core part.

이와같이 이젝타봉(14)이 슬라이드코어(9)의 경사직전 A점까지 도달하였으나 첨부도면 제3도에서는 이젝터판(5)(6)이 계속 상승함으로서 경사핀(8)에 의한 슬라이드 코어(9)가 위로 상승하면서 금형의 안쪽으로 들어간다.In this way, the ejector rod 14 reached the point A just before the inclination of the slide core 9, but in the attached drawing 3, the ejector plate 5, 6 continued to rise so that the slide core 9 by the inclined pin 8 Ascend upwards and enter the inside of the mold.

이때 이젝터봉(14)은 tan만큼의 각도를 가지므로서 시간이 경과함에 따라서사출기의 밀핀(15)보다도 올라가는 속도가 tan의 거리만큼 더 빨리 올라감으로서 밀핀(15)보다 이젝터봉(14)의 속도차에 의해서 성형품의 안더컷 부위를 쳐줌으로서 성형품이 완전 취출되는 것이다.At this time, the ejector rod 14 is tan As time elapses with the angle of ascending speed, the speed of ascending than the mill pin 15 of the injection machine is tan. The molded article is completely taken out by hitting the cut portion of the molded article by the speed difference of the ejector rod 14 rather than the mil pin 15 by moving up by a distance of.

위와같이 본 고안은 경사편(8)과 슬라이드코어(9)와 이젝타봉(14)에 의해서 작동함으로 간단한 구성으로 2단 취출할 수 있으므로서 금형의 제작가공 공수가 종래의 것보다 작게 들고 금형 자제의 무게가 줄어들고 원가절감을 할 수 있으며, 급속 귀환계통(Quick Return System)에도 이용 가능하므로 여러목적으로도 이용 가능한 유용한 고안이다.As described above, the present invention is operated by the inclined piece 8, the slide core 9 and the ejector rod 14, so that it can be taken out in two stages with a simple configuration. It can reduce weight, reduce cost, and can be used for a quick return system.
