본 고안은 사출금형을 3단으로 취출되도록 구성하여 런너를 자동으로 취출할 수 있도록 한 사출금형의 3단취출 장치에 관한 것이다.The present invention relates to a three-stage take-out device of the injection mold configured to take out the injection mold in three stages to automatically take out the runner.
종래에는 사출금형으로 사출함에 있어서, 런너와 게이트, 성형품을 동시에 취출 하였기 때문에 성형품의 외관에 백화현성 및 수축현상이 발생되어 성형품의 취출이 어렵게 되었고 취출된 성형품이 손상되어 불량품발생률이 높게되는 문제점이 있었다.In the conventional injection molding, the runner, the gate, and the molded article were taken out at the same time, so whitening and shrinkage occurred in the appearance of the molded article, which made it difficult to take out the molded article. there was.
본 고안은 상기와 같은 점을 감안하여 성형품을 취출할때 런너를 3단계로 취출토록 안출한 것으로 이를 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been made to take out the runner in three stages when taking out the molded article in consideration of the above-mentioned point in detail based on the accompanying drawings as follows.
즉, 하부취부판(1)에 받침판(2), 밑판(5), 봉지지판(8)을 차례로 적층설치하되, 봉지지판(8)은 이젝트봉(11)상에 올려지도록 설치하며 상기 각판체들은 연결봉(13)(14)과 이젝트핀(12)(15)으로 상봉금형체(16)에 연결설치되고 받침판(2)에는 걸림봉(9) 설치봉(3)을 형성하며 이의 일측에 조정봉(4)을 설치하고 걸림봉(9)은 걸림턱(10)을 형성하여 봉지지판(8)에 설치하되, 받침판(2)의 설치공(3)에 위치시키고 걸림턱(6)과 받침턱(7)을 가진 밀판(5)을 관통토록 설치한다.That is, the supporting plate (2), the bottom plate (5), the rod supporting plate (8) are sequentially installed on the lower mounting plate (1), but the rod supporting plate (8) is installed to be mounted on the eject rod (11). They are connected to the upper rod mold 16 by connecting rods 13, 14 and eject pins 12 and 15, and the supporting plate 2 forms a locking rod 9 and an installation rod 3 on one side thereof. 4) and the locking rod (9) is formed on the rod support plate (8) by forming a locking jaw (10), located in the installation hole (3) of the support plate (2) and the locking jaw (6) and the support jaw ( 7) Install the plate (5) with the through.
상부금형체(16)에는 경사면(18)을 가진 텃치블럭(17)을 설치하고 이의 하방에는 받침판(2)에 설치되는 록킹캠(19)을 스프링(20)으로 탄력설치하며, 연결봉(13)상단에는 사각밀편(21)을 설치토록 구성하여 된 것으로 미설명부호 22는 성형품이다.The upper mold 16 is provided with a quench block 17 having an inclined surface 18, and a lowering portion of the locking cam 19 installed on the support plate 2 is elastically installed with a spring 20, and a connecting rod 13 is provided. It is configured to install a square milling 21 in the upper end, and reference numeral 22 is a molded article.
이상과 같이 구성된 본 고안은 제1도와 같이 성형품의 사출이 끝나게 되면 제품이 성형되는데, 제품을 취출하기 위하여 이젝트봉(11)을 상승시키면, 이에 지지된 봉지지판(8)이 제2도에서와 같이 X거리만큼 1차 상승되고 이때 걸림봉(9)은 봉지지판(8)과 함께 상승된다.In the present invention configured as described above, when the injection of the molded product is finished as shown in FIG. 1, the product is molded, and when the eject rod 11 is raised to take out the product, the supporting plate 8 supported therefrom is shown in FIG. As described above, the first distance is increased by the X distance, and the locking rod 9 is raised together with the rod support plate 8.
걸림봉(9)이 봉지지판(8)과 함께 상승되면 이의 걸림턱(10)이 밑판(5)의 걸림턱(6)에 걸려 밑핀(5)을 제3도에서와 같이 Y거리만큼 2차 상승시키며 받침판(2)은 밑판(5)과 함께 동시에 상승된다.When the catching rod 9 is raised together with the rod supporting plate 8, the catching jaw 10 thereof is caught by the catching jaw 6 of the base plate 5, and the bottom pin 5 is secondary by Y distance as shown in FIG. 3. While supporting the base plate 2 is simultaneously raised with the base plate (5).
이와 같이 밑판(5)과 받침판(2)이 상승되면 조정봉(4)이 상부금형체(16)에 걸려 받침판(2)의 상승이 정지되며 록킹캠(19)은 텃치블럭(17)의 경사면(18)에 의해서 일측으로 밀리면서 밑판(5)을 받침판(2)에서 분리시키고 Z거리만큼 3차 상승된다.As such, when the bottom plate 5 and the support plate 2 are raised, the adjusting rod 4 is caught by the upper mold body 16 and the ascending of the support plate 2 is stopped, and the locking cam 19 is inclined surface of the quench block 17 ( 18) while pushing to one side by separating the base plate (5) from the base plate (2) and is raised three times by the Z distance.
이와 같이 각판체가 이젝트봉(11)과 록킹캠(19)에 의해서 3단계로 상승할때 연결봉(13)(14)과 이젝트핀(12)(15)들이 함께 상승되고 이들의 상승순서대로 성형품이 취출되며 최종적으로 사각밀편(21)이 성형품(22)을 밀어올려 이의 취출을 완료시키는 것이다.In this way, when each plate is raised in three steps by the eject rod 11 and the locking cam 19, the connecting rods 13, 14 and the eject pins 12, 15 are lifted together, and the molded products are lifted in the rising order. Finally, the square milling piece 21 pushes the molded article 22 to complete the extraction thereof.
한편, 상기 판체들은 이젝트봉(11)이 하강함에 따라 상기의 역으로 함께 하강되어 다음 성형을 기다리게 된다.On the other hand, the plate is lowered together in the reverse direction as the eject rod 11 is lowered to wait for the next molding.
이상과 같은 본 고안은 간단한 구조로서 성형품을 3단계로 취출하므로서 이의 작업이 간편하고 취출되는 성형품의 외관에 백화현상이나 수축현상이 발생되지 않으므로 양질의 성형품을 제작할 수 있는 등의 특징을 지닌 것이다.The present invention as described above has a feature that it is possible to produce a high-quality molded article because it is easy to work and the whitening or shrinkage does not occur in the appearance of the molded article to be taken out in three steps as a simple structure.
