본 고안은 사출금형에서 경사면 보스(Boss)의 언더컷 처리를 위한 금형구조에 관한 것이다.The present invention relates to a mold structure for the undercut treatment of the inclined boss (Boss) in the injection mold.

본 고안은 이제까지 어려운 문제로 알려져 왔던 경사면 보스의 언더컷을 용이하게 처리할 수 있는 금형을 제공하는 것을 목적으로 하여, 가동측형판(2)에 형성된 경사구멍에 삽입되도록 스프링(8)이 중앙 외주연부에 설치된 슬라이드 코어핀(7)을 내장하여 맞춤핀(6)으로 서로 체결되어 있는 슬라이드코어(9)와, 상기 슬라이드코어(9)를 슬라이딩 할 수 있도록 지지하는 슬라이드코어 가이드블럭(10)과, 사익 슬라이드코어(9)의 작동거리를 한정하여 주는 슬라이코어 정지핀(11)과 슬라이드 코어(9)를 받쳐주도록 받침판(4)에 형성된 경사블럭(5)으로 구성되는 것을 특징으로 하는 경사면 보스의 언더컷 처리용 금형인 것이다.The object of the present invention is to provide a mold capable of easily processing the undercut of the inclined boss, which has been known as a difficult problem so far. A slide core pin (7) built in the slide core (9) fastened to each other with a dowel pin (6) and a slide core guide block (10) for supporting the slide core (9) to be slidable; Slope core stop pin 11 for limiting the working distance of the slide slide core (9) and the inclined boss (5) formed on the support plate (4) to support the slide core (9) It is a mold for undercut processing.

첨부된 도면을 참고하여 본 고안을 설명하면 다음과 같다.Hereinafter, the present invention will be described with reference to the accompanying drawings.

제1도는 본 고안에 따른 금형이 닫힌 상태를 도시하는 것으로서, 슬라이드코어핀(7), 슬라이드코어(9), 슬라이드코어 가이드블럭(10), 슬라이드코어 정지핀(11) 및 경사블럭(5)의 형상 및 결합상태를 상세히 도시하고 있는 것이다.1 is a view showing a closed state of the mold according to the present invention, the slide core pin (7), slide core (9), slide core guide block (10), slide core stop pin (11) and inclined block (5). It is shown in detail the shape and bonding state.

슬라이드코어핀(7)과 슬라이드코어(9)는 맞춤핀(6)으로 결합되어 있으며, 슬라이드코어 가이드블럭(10)은 상기 슬라이드코어(9)가 슬라이딩 할 수 있도록 되어 있으며 슬라이드 코어(9)의 작동거리를 결정하는 슬라이드코어 정지핀(11)이 상기 가이드 블럭(10)에 조립설치 되어서 가동측형판(2)에 고정되어 있다. 경사블럭(5)은 슬라이드코어(9)의 뒷면을 받쳐주도록 받침판(4)에 조립설치되어서 슬라이드 코어핀(7)이 받는 성형압력을 지지해주는 것이다.Slide core pin (7) and the slide core (9) is coupled to the dowel pin (6), the slide core guide block 10 is to allow the slide core (9) to slide and the slide core (9) A slide core stop pin 11 for determining the working distance is assembled to the guide block 10 and fixed to the movable side plate 2. The inclined block 5 is assembled to the support plate 4 so as to support the rear surface of the slide core 9 to support the molding pressure received by the slide core pin 7.

제1도에서와 같이 금형이 닫힌 상태에서 사출이 완료되어 금형이 열리게 되면 먼저 가동측형판(2)과 받침판(4)의 사이가 열리면서 경사블럭(5)이 슬라이드 코어(9)를 언더컷량(P)만큼 끌고나와 슬라이드 코어 핀(7)이 경사면 보스로 부터 빠져나오게 된다. 이후 정지핀(11)에 의해 결정되는 작동거리만큼 스프링(8)에 의하여 슬라이드코어(9)가 완전히 후퇴되어 슬라이드코어 가이드블럭(10)의 슬라이드코어정지핀(11)에 의해 지지된다.As shown in FIG. 1, when injection is completed while the mold is closed and the mold is opened, the inclined block 5 undercuts the slide core 9 while the movable side plate 2 and the support plate 4 are opened. The slide core pin (7) is pulled out of the slope boss. Thereafter, the slide core 9 is fully retracted by the spring 8 by the operating distance determined by the stop pin 11 and is supported by the slide core stop pin 11 of the slide core guide block 10.

이 동작이 끝나면 고정 측형판(1)과 가동측형판(2)의 사이가 열이고 이젝터핀(3)에 의해 성형품(13)을 취출하게 된다. 성형품(13)이 취출이 완료되어 금형이 닫힐때에도 슬라이드코어 정지핀(11)과 스프링(8)에 의해서 후퇴되었을 때의 상태(제1도)를 그대로 유지하게 되므로 무리가 없고 위험성없이 작동하게 된다. 제3도는 제1도의 A-A선 단면도로서, 슬라이드 코어(9)와 슬라이드 코아 가이드블럭(10)의 형상 및 결합상태를 상세히 도시하고 있다.When this operation | movement is complete | finished, between the stationary side plate 1 and the movable side plate 2, it will heat and the molded article 13 will be taken out by the ejector pin 3. As shown in FIG. When the molded product 13 is taken out and the mold is closed, the state when the retracted by the slide core stop pin 11 and the spring (8) is maintained as it is (Figure 1), so there is no problem and operates without risk. . FIG. 3 is a cross-sectional view taken along the line A-A of FIG. 1 and shows in detail the shape and coupling state of the slide core 9 and the slide core guide block 10. As shown in FIG.

이상 설명된 바와 같이, 본 고안에 따른 금형을 사용하면 이제까지 어려운 문제로 알려져 왔던 경사면 보스의 언더컷이 용이하게 처리되므로 성형품의 품질성향상 및 제품의 기능향상에 크게 이바지하게 된다.As described above, since the undercut of the inclined boss, which has been known as a difficult problem, is easily handled using the mold according to the present invention, it greatly contributes to the improvement of the quality of the molded product and the function of the product.
