Description
제1도는 본 고안의 반출전 상태를 나타낸 단면도.1 is a cross-sectional view showing a state of carrying out the subject innovation.
제2도는 반출후의 단면도.2 is a cross-sectional view after taking out.
본 고안은 나사 특히, 사출물의 암나사로부터의 나사 성형부가 종전의 모우터 구동방식에서 이젝터 블록방식으로 쉽게 분리되도록 개량한 암나사 성형물의 성형 반출장치에 관한 것으로서, 원가 절감 효과를 거두기 위한 목적을 갖고 있다.The present invention relates to a molding apparatus for ejecting female thread moldings in which the screw molding part from the female thread of the injection molding, in particular, is easily separated from the conventional motor driving method by the ejector block method, and has an object of reducing cost. .
이미 실시되고 있는 같은 종류의 성형 반출장치로서는, 나사코어를 모우터로 회전시켜 빼내는 구조로된 것이 주종을 이룬다. 그러나 이런 장치는 나사코어의 회전으로 인한 위치 결정의 오차 및 추력이 발생하지 않도록하기 위해서는 베어링을 사용해야 할 뿐만 아니라, 감속에 필요한 워엄과 워엄기어를 별도로 갖춰야하기 때문에 제조원가면에서 대단히 불리하고, 제조면에서도 어려운 점이 많았다.As the molding discharging device of the same type already implemented, the main one is a structure in which the screw core is rotated by a motor and taken out. However, such a device is very disadvantageous in terms of manufacturing cost because it is necessary to use bearings in order to prevent the positioning error and thrust caused by the rotation of the screw core, and to equip the worm and worm gear necessary for deceleration. There were many difficult points.
본 고안은 이 같은 종래의 결점을 해소하기 위해 고안된 것이다. 이하 본 고안의 바람직한 실시에를 첨부 도면을 참조하여 상세히 설명한다. 상형판(1) 상에 사출 성형부(2)가 있고 하형판(3) 상에 암나사 성형구조가 있는 것에 있어서, 하형판(3) 상에 상협하광형의 쐐기부(4)를 형성하고, 이 쐐기부(4)에 의하여 윗쪽이 오므라들거나 벌어질 수 있고 또한 분할된 이젝터 블록(5)을 유압 또는 공압 피스턴(6) 상단에 피봇지지되도록 설치한 것이다.The present invention is designed to solve such a conventional drawback. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the injection molding part 2 on the upper mold board 1 and the female screw molding structure on the lower mold board 3, the wedge part 4 of the upper and lower light beam type is formed on the lower mold board 3, The wedge part 4 is able to be lifted up or opened and the divided ejector block 5 is installed so as to pivot on the hydraulic or pneumatic piston 6.
이와 같이 구성된 본 고안에 있어서, 상형판(1)과 하형판(3)이 밀착되고 이젝터블록(5)이 상형판(1)의 성형부(2)에 성형준비자세로 위치한 상태에서 소재의 사출성형이 완료되고나서 실린더(7) 내에 상승유압을 가하면 피스턴(6)이 이젝터블록(5)을 밀어올리게 된다.In the present invention configured as described above, the injection of the material with the upper plate (1) and the lower plate (3) in close contact and the ejector block (5) is located in the molding ready position on the forming portion (2) of the upper plate (1) After the molding is completed, when the hydraulic pressure is applied to the cylinder 7, the piston 6 pushes up the ejector block 5.
이 때 이젝터블록(5)은 쐐기부(4)의 유도에 의해서 상승할 수록 상부쪽이 중심을 향해 오므라든다. 그러다가 성형물(8)의 암나사부에서 이젝터블록(5)의 나사성형부(5a)가 완전히 벗어나게되면 성형물(8)은 이젝터블록(5)으로부터 분리 반출되는 것이다.At this time, as the ejector block 5 rises by the induction of the wedge portion 4, the upper side rises toward the center. Then, when the threaded portion 5a of the ejector block 5 is completely released from the female threaded portion of the molding 8, the molding 8 is separated out from the ejector block 5.
이상과 같은 본 고안은 암나사 성형후의 제품 반출에 있어서 구조가 간단하므로 제조원가 절감효과가 매우 크며, 또한 반출시간도 매우 짧아 생산성 면에서 괄목할만 하다.The present invention as described above has a very large cost reduction effect due to the simple structure in the product carrying out after the female thread molding, and also very short take-out time is remarkable in terms of productivity.
