본 고안은 사출금형에 있어서 TV캐비네트와 같이 제품의 내측에 형상이 복잡하여 제품취출이 어렵고 외관 품질을 중요시하는 제품을 성형시킨 상태에서 취출시 2중밑판을 사용하게 취출시킬 수 있도록 한 사출금형의 2단 취출장치에 관한 것이다.The present invention is an injection mold that allows the use of a double bottom plate when taking out a product that is difficult to take out the product and the appearance quality is important because the shape is complicated inside the product like the TV cabinet in the injection mold. It relates to a two-stage extraction device of.
종래에 사출금형에 있어서는 TV캐비네트와 같이 제품의 내측에 형상이 복잡하여 제품취출이 어렵고 외관품질을 중요시하는 제품을 성형시킨 상태에서 취출시 2중 밀판을 사용하여 연속적으로 용이하게 취출시킬 수 있도록 한 사출 금형의 2단 취출장치에 관한 것이다. 종랭의 사출금형에 있어서는 TV캐비네트와 같이 제품의 내측에 형상이 복잡하여 제품 취출이 어렵고 외관 품질을 중요시하는 제품을 성형시킨 상태에서 취출시 도면 제6도에 도시된 바와 같이 구조상 4면 슬라이드코아(1) 때문에 에젝터핀(11)이와에 다른 취출기구 장치가 어려움에 따라 에젝터핀만을 이용하여 1단으로 제품을 취출하던 관계로 제품 취출이 어려울 뿐만 아니라, 에젝터핀에 부하가 많이 걸리기 때문에 제품외관에 백화현상 및 변형이 발생하여 생산성저하 및 불량이 많이 발생하던 결점이 있었다.Conventionally, in the injection mold, it is difficult to take out the product because the shape is complicated inside the product like the TV cabinet, and it can be easily taken out continuously by using the double-mild plate when taking out the product in which the appearance quality is important. It relates to a two-stage take-out device of one injection mold. In the injection mold of longitudinal cooling, it is difficult to take out the product because the shape is complicated inside the product like the TV cabinet, and when the product is taken out in a state where the appearance quality is important, as shown in FIG. (1) Due to the difficulty of ejector pins 11 and other ejection device devices, the product is difficult to take out due to the fact that the ejector pins are taken out using only the ejector pins. As a result, whitening phenomenon and deformation occurred in the appearance of the product, which resulted in a decrease in productivity and defects.
따라서 본 고안은 이와같은 종래의 결점을 해결하기 위하여 안출된 것으로 첨부된 도면에 의하여 그 구성과 작용효과를 설명하면 다음과 같다.Therefore, the present invention is devised to solve such a conventional drawback and the configuration and operation effects by the accompanying drawings as follows.

The spacer pin 6 and the lower fixing plate 7 are installed at the lower portion thereof, and then the return pin 10 and the ejector pin are attached to the upper pin support plate 9 fixed to the upper sealing plate 8. (11) and the runner knife pin 12, and the lower plate (3) and the lower plate while fixing the return pin (10 ') to the lower pin support plate (9') fixed to the lower plate (8 ') Between the 8 'and between the lower plate 3 and the upper plate 8, which is operatively connected to the lower end by the ejector rod 13, the springs 14 and 14' are respectively resilient. After the support is installed, the chuck block 16 with the sliding jaw 15 protruding toward the upper front portion is fastened to the lower fixing plate 7 using bolts, and the lower end of the upper sealing plate 8 is lowered. Locking blocks 18 and 18 'having the locking jaws 17 and 17' formed on the surface thereof are fastened by fixing bolts, and sliding jaws 15 'are provided on the inner central portion of the lower plate support plate 9' to the outside thereof. Guide clamps on both sides of the clamp 19 are fixed to both sides of the clamp 19 to prevent left and right flow, while the clamp 19 is fixed by fixing bolts having springs 14 " 20) (20 ') is provided, and reference numeral 21 is a molded product.
이와같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
도면 제1도에 도시된 바와같이 일단 사출성형이 완료된 상태에서 먼저 도면에 도시되지 않은 상부형판과 스트리피판(2) 사이가 열리면서 슬라이드코아(1)가 성형품(21)에서 빠지게되고 여기에서 상, 하부밀판(8) (8')은 하강되어 있는 상태에서 이어서, 에젝터봉(13)이 동작 상부판지지판(9), 상부밑판(8)을 상방향으로 밀고 올라가면 1차적으로 상부밀판(8)에 장착되어 있던 록킹블록(18) (18')이 도면 제5도에 도시된 바와 같이 그 하단 전면부로 형성된 걸림턱(17) (17')에 의해 하부판지지판(9')에 장착된 클램프(19)와 록킹됨에 따라 하부판지지판(9'), 하부밀판(8')이 상부핀지지판(9), 상부밑판(8)과 함께 도면 제2도에 도시된 바와 같이 일정스트로크 H만큼 올라가게되고 계속해서 도면 제3도에 도시된바와 같이 에젝터봉(13)이 계속 전진하면서 상부밑판(8)을 밀게되면 도면 제4도에 도시된 바와 같이 하부고정판(7)에 체결되어 있던 텃치블록(16)의 상단 슬라이딩턱(15)과 클램프(19)의 내측중간부에 형성된 슬라이딩턱(15')이 접촉되면서 돌출된 슬라이딩턱(15) (15')의 돌출된 두께만큼 클램프(19)가 스프링(14")을 압축시키면서 탄력적으로 외측으로 밀리면서 클램프(19)의 하단부에 걸림턱(17) (17')에 의해 걸려있던 록킹블록(18) (18')이 걸림이 이탈됨과 동시에 상부밀판(8)과 하부밀판(8')이 분리되면서 상부밑판(8), 상부핀지지판(9)은 나머지스트로크 Z만큼 올라가게되면서 도면 제3도에 도시된 바와 같이 에젝터핀(11)에 의해 2차적으로 성형품(21)을 완전취출시키게되고, 이때, 하부핀지지판(9'), 하부밑판(8')은 스프링(14)에 의해 내려오게 되고 성형품(21) 취출이 끝나면 리턴핀(10)과 스프링(4')의 스프링턱에 상측밑판(8)이 하강하면서 상기에 서술된 바와 같이 동작의 역으로 이루어지며 닫힐 수 있게 된 것으로 본원은 상기의 작동으로 스트리피판에 의하여 성형품이 1차적으로 금형에서 이탈되며 이어서 에젝터봉에 의해 밑판이 연속 상승함에 따라 제품이 완전히 금형을 이탈해서 제품을 용이하게 취출할 수 있게 됨에 따라 연속적인 제품이 완전하게 깨끗이 취출될 수 있을 뿐만 아니라, 작업능률향상과 제품품질향상 및 원가를 절감할 수 있게 된 것이다.As shown in FIG. 1, once the injection molding is completed, the slide core 1 is removed from the molded article 21 while the upper mold and the stripe plate 2, which are not shown in the drawing, are first opened. When the lower plate 8 (8 ') is lowered, the ejector rod 13 pushes up the operation upper plate support plate 9 and the upper bottom plate 8 upwards, and the upper plate 8 is primarily Clamps mounted on the lower plate support plate 9 'by the locking jaws 17 and 17' formed at the lower front face portion thereof as shown in FIG. As shown in FIG. 2, the lower plate supporting plate 9 'and the lower sealing plate 8' are raised together with the upper pin supporting plate 9 and the upper lower plate 8 as shown in FIG. Then, as shown in FIG. As shown in FIG. 4, the upper sliding jaw 15 of the quench block 16, which is fastened to the lower fixing plate 7, and the sliding jaw 15 ′ formed at the inner middle portion of the clamp 19 are in contact with each other. The clamping jaw 17 (17 ') at the lower end of the clamp 19 is pushed outwardly while the clamp 19 compresses the spring 14 "by the protruding thickness of the protruding sliding jaw 15 (15'). The locking block 18 (18 ') held by the lock is released and the upper plate 8 and the lower plate 8' are separated and the upper bottom plate 8 and the upper pin support plate 9 are rested. As shown in FIG. 3, the molded article 21 is completely taken out by the ejector pin 11 while being raised by Z. At this time, the lower pin support plate 9 'and the lower base plate 8' are removed. ) Is lowered by the spring 14 and when the molded product 21 is taken out, the upper base plate 8 is lowered on the spring jaws of the return pin 10 and the spring 4 '. As described above, the reverse of the operation is made and can be closed. In this operation, the molded article is firstly removed from the mold by the strippy plate, and then the product is continuously raised by the ejector rod. As the product can be easily taken out by removing the mold completely, the continuous product can be taken out completely, and the work efficiency, product quality and cost can be reduced.
