본 고안은 언더컷이 형성되는 제품, 특히 내측 언더컷의 제품의 언더컷 처리를 원활하게 할 수 있도록한 내측 언더컷 처리장치에 관한 것이다.The present invention relates to an inner undercut processing apparatus that facilitates the undercut treatment of a product in which an undercut is formed, especially a product of the inner undercut.

종래에는 내측 언더컷이 형성되는 제품을 한번에 성형 생산할 수 없었으며 취출이 어려운 실정이었다. 따라서, 성형품에 가급적 언더컷 형성을 피할 수밖에 없었던바, 불가피할 경우에는 분할 성형으로 생산하고 있는 등의 문제점이 있었다.Conventionally, the product in which the inner undercut is formed could not be molded and produced at a time, and it was difficult to take out the product. Therefore, there was no choice but to avoid the formation of undercuts in the molded product, if necessary, there were problems such as producing by division molding.

본 고안은 상기와 같은 종래의 문제점을 감안하여 언더컷을 가진 제품의 성형과 취출을 원활하게 할 수 있도록 안출한 것으로 이를 첨부한 도면에 의거하여 상세히 섬령하면 다음과 같다.The present invention has been made in order to facilitate the molding and take-out of the product having an undercut in view of the conventional problems as described above in detail based on the accompanying drawings as follows.

가동측 취부판(1) 상부에 경사홈(4)(5)을 가진 이젝트편(2)(3)을 대향설치하고 이의 상부에는 홀더(7)(8)를 가진 가동측형판(6)을 설치하며 홀더(7)(8)의 내측에 돌출봉(12)(13)을 가진 내측코어(10)(11)를 앵글코어(9)를 중심으로 대향되게 설치하여서 구성된 것으로 도면중 미설명부호 14는 언더컷(15)을 가진 제품을 나타낸 것이다.Eject pieces (2) (3) having inclined grooves (4) and (5) are disposed on the upper side of the movable side mounting plate (1), and movable side plate (6) having holders (7) and (8) on the upper side thereof. The inner core 10, 11 having the protruding rods 12, 13 on the inner side of the holder (7) (8) is installed so as to be opposed to the angle core (9). 14 shows a product with an undercut 15.

이와같이 구성된 본 고안은, 제1도에 도시된 바와같이 하강되어 있을때는 내측코어(10)(11)가 벌어져 있으며 이상태에서 제품(14)을 성형(도시되지 않은 브라켓 내부의 실린더에 연결 구성된 링크와 이젝트편(2)(3)이 피스톤로드를 통하여 판넬(제품. 기판공물)을 지지토록됨)하게 되고, 제품(14) 성형후 가동측 취부판(1)의 이젝트편(2)(3)을 상승시키면 이의 경사홈(4)(5)이 내측코어(10)(11)의 돌출봉(12)(13)을 밀어 내측코어(10)(11)가 앵글코어(9)를 중심으로 하여 내측으로 오므라들면서 상승시키게 되며 이에따라 제2도에서와 같이 제품(14)의 언더컷(15) 부분이 내측코어(10)(11)에서 이탈(실린더의 피스톤로드가 상부로 전지함으로써 이젝트편(2)(3) 상부의 홀더(7)(8)에 의해 판넬(피가공물. 제품)이 지지됨)되게 되고 내측 코어(10)(11)의 측압력은 홀더(7)(8)가 억제하게 되는 것이다.The present invention configured as described above, when lowered as shown in Figure 1, the inner core (10) (11) is open and in this state to form the product (14) link (connected to the cylinder inside the bracket not shown) Eject piece (2) (3) is to support the panel (product.substrate work) through the piston rod, the ejection piece (2) (3) of the movable side mounting plate (1) after molding the product (14) When the inclined grooves 4, 5 push the protruding rods 12, 13 of the inner core 10, 11, the inner core 10, 11 is centered on the angle core 9 As a result, as shown in FIG. 2, the undercut 15 portion of the product 14 is disengaged from the inner core 10, 11 (the piston rod of the cylinder is pulled upward, thereby ejecting the piece 2). (3) The panel (workpiece) is supported by the upper holder (7) (8) and the side pressure of the inner core (10) (11) is to be suppressed by the holder (7) (8) It is.

한편, 상기 과정에서의 세부작동을 설명하면, 제품의 취출시 이젝트편(2)(3)의 상승으로 돌출봉(12)(13)을 통해 내측코어(10)(11)에 상승력이 전달되어 홀더(7)(8)의 경사부와 앵글코어(9)의 경사부 및 이젝트편(2)(3)의 경사홈(4)(5)으로 이루어지는 상호 접동작동에 의해 상기 내측코어(10)(11)가 tan값만큼 내측으로 후퇴를 하게되는 바, 취출이 용이하게 되게 된다.On the other hand, when explaining the detailed operation in the above process, the lifting force is transmitted to the inner core (10) 11 through the protruding rods (12) 13 to the rise of the ejection pieces (2) (3) when taking out the product The inner core 10 is formed by the mutual sliding operation consisting of the inclined portion of the holder 7 and 8, the inclined portion of the angle core 9 and the inclined grooves 4 and 5 of the eject piece 2 and 3. (11) tan Since the retreat to the inner side by the value, it is easy to take out.

이상과 같은 본 고안은 이젝트편이 내측코어에 안내작동됨으로써 언더컷을 쉽게 처리할 수 있으며 이에따라 언더컷을 가진 제품을 용이하게 생산해낼 수 있는 점등의 특징을 지닌 것이다.The present invention as described above is characterized in that the ejection piece is guided to the inner core can easily handle the undercut and accordingly the lighting features that can easily produce a product with an undercut.
