본 고안은 사출금형의 긴 성형품에 있어서 에젝터가 필요없이 경사면에서 제품을 안전하게 취출할 수 있게된 사출금형의 긴성형품 경사구멍 언더컷 처리장치에 관한 것이다.The present invention relates to a device for inclined hole undercut treatment of a long molded article of an injection mold, which enables to safely take out a product from an inclined surface in the long molded article of an injection mold without the need for an ejector.

종래의 사출금형의 긴 성형품 경사구멍 언더컷 처리할 경우에 대부분이 에젝터 자욱이 제품에 남아 있음에 따라 긴성형품 및 원형의 성형품등 모든 경사면 상으로 된 제품의 품질이 저하되던 결점이 있었다.In the case of the process of undercutting a long molded article of a conventional injection mold, most of the ejector traces remain in the product, and thus, the quality of a product on all inclined surfaces such as a long molded article and a circular molded article has been deteriorated.

본 고안은 이와 같은 종래의 결점을 해결하기 위하여 안출되 것으로 첨부된 도면에 의하여 그 구성과 작용효과를 설명하면 다음과 같다.The present invention will be devised to solve such a conventional drawback when explaining the configuration and effect by the accompanying drawings as follows.

가동측 형판(1)과 고정측 형판(1')에 각각 가동측 코어(2)와 고정측 코어(2')가 장착되고 고정측 형판(1')에는 경사면으로 된 안내홈내에 슬라이드코어(3)가 삽입 장착되고 또한 슬라이드 코어(3) 내측으로는 앵귤러핀(4)이 삽입되고 고정측 고정판(5)하면 일측에는 녹킹블록(6)이 장착되고 고정측 형판(1')에는 안장봉(7)을 안내하는 부시(8)가 고정되고 인장봉(7) 끝단부에는 와셔(9)가 볼트(10)에 의해 체결되어서 구성되어진 것으로 미설명 부호 11은 성형품인 것이다.The movable side core 1 and the fixed side core 2 'are mounted on the movable side template 1 and the fixed side template 1', respectively, and the fixed side template 1 'is provided with a slide core in a guide groove formed as an inclined surface. 3) is inserted and the angular pin (4) is inserted into the slide core (3) and the fixed side fixing plate (5) is equipped with a knocking block (6) on one side and the saddle rod on the fixed side template (1 ') Bush (8) for guiding (7) is fixed and the end of the tension rod (7) is composed of a washer (9) is fastened by the bolt 10, reference numeral 11 is a molded article.

이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

상기과 같이 조립된 본원은 사출금형의 긴성형품, 경사구멍 언더컷 처리장치로써 일단 금형이 열리기 시작하면 도면 제2도에 도시된 바와 같이 고정측 형판(1')에 장착된 고정측 코어(2'), 슬라이드코어(3), 앵귤러핀(4)이 동시에 작동하게 된 후 도면 제2도에 도시된 바와 같이 스트로크 S만큼 이동함에 따라 도면 제3도에 도시된 바와 같이 고정측 고정판(5')자 고정측 형판(1')이 분리되면서 앵귤러핀(4)에 의해 슬라이드 코어(3)가 작동함으로써 성형품(11)을 쉽게 취출할 수 있게된 것으로 일단 금형이 닫힐 경우에는 상기의 역순동작에 의해 녹킹블록(6)이 슬라이드코어(3)를 밀어주게 됨에 따라 본원은 슬라이드코어(3) 에젝터 역활을 대신하는 것으로 에젝터를 사용하지 않고도 성형품(11)을 쉽고도 안전하게 취출할 수있을 뿐만 아니라 제품의 품질을 향상시키고 또한 모든 경사를 갖는 긴 성형품 및 원형의 성형품등에 있어 종래의 어려웠던 점을 해결하게 된 것이다.The assembled as described above is the injection molding long molded article, inclined hole undercut treatment device once the mold starts to open as shown in Figure 2 fixed side plate 2 'mounted on the fixed side template (1') as shown in FIG. After the slide core 3 and the angular pin 4 are operated at the same time, as shown in FIG. 2, the fixed side fixing plate 5 'is moved as shown in FIG. When the fixed side template 1 'is separated, the slide core 3 is operated by the angular pin 4 so that the molded product 11 can be easily taken out. When the mold is closed, knocking is performed by the above reverse operation. As the block 6 pushes the slide core 3, the present application replaces the slide core 3 ejector role, and it is possible to easily and safely take out the molded product 11 without using an ejector. To improve the quality of And also there will be a resolution of the conventional difficult points, etc. The molded article of a long molded product having a circle and all the gradient.
