본 고안은 비교적 긴 보스를 가진 제품의 성형을 안정적으로 하고, 이의 취출시 보스의 변형을 방지할 수 있도록 한 긴 보스를 가진 제품의 성형 장치에 관한 것이다.The present invention relates to a molding apparatus of a product having a long boss to make the molding of the product having a relatively long boss stable, and to prevent the deformation of the boss when taking out.

종래에도 긴 보스를 가진 제품을 성형하는 금형장치가 안출된 바 있으나, 이는 성형부를 보다 깊게 형성하고, 이에 코어핀을 삽입시켜 성형하고 있었으며, 성형 후 취출작업시 상기 코어핀과 고정측 형판의 파팅 작업만으로 제품을 취출하도록 하므로써 제품의 취출시 보스 부분이 굽혀지거나 변형되는 일이 종종 발생되었고, 또 보스의 끝단 처리가 원활하게 이루어지지 않게 되므로 이 부분을 재 가공하여야 했으며, 또 취출시의 이형성이 좋지 못하여 제품의 성형 불량이 발생되는 점 등의 문제점이 있었다.Conventionally, a mold apparatus for molding a product having a long boss has been conceived, but this has been formed deeper and formed by inserting a core pin therein, and parting of the core pin and the fixed side template during take-out work after molding By taking out the product only by work, the boss part is often bent or deformed when taking out the product, and because the end treatment of the boss is not made smoothly, this part has to be reprocessed, and the releasability at the time of taking out There was a problem such as poor molding of the product is not good.

본 고안은 상기와 같은 종래의 문제점을 감안하여 비교적 긴 보스를 가진 제품의 성형을 안정적으로 하고, 이의 변형률을 최소한으로 줄이면서 취출을 용이하게 할 수 있도록 안출한 것으로, 이를 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention is designed to stabilize the molding of a product having a relatively long boss in consideration of the conventional problems as described above, and to make it easy to take out while reducing the strain thereof to a minimum, based on the accompanying drawings It will be described in detail as follows.

하판(1)에 이젝터(2)와 스페이스 블럭(3)을 설치하고, 이의 상부에 성형부(5)를 가진 가동측 형판(4)을 설치하며, 이의 상방에 게이트(7)와 코어핀(8)을 가진 고정측 형판(6)을 설치한 것에 있어서, 상기 가동측 형판(4)의 코어핀(8)삽입부에 벤트홀(9)을 형성하고, 이의 상단 위치에 홈(11)이 형성된 록킹부(10)를 형성토록 구성된 것으로 12는 제품이다.The ejector 2 and the space block 3 are provided on the lower plate 1, and the movable side template 4 having the molding part 5 is installed on the upper plate 1, and the gate 7 and the core pins are disposed on the upper plate 1 above. In the case where the fixed side template (6) having the base plate (8) is provided, a vent hole (9) is formed in the core pin (8) insertion portion of the movable side template (4), and the groove (11) It is configured to form the formed locking portion 10, 12 is a product.

이상과 같이 구성된 본 고안은 제1도와 같이 가동측 형판(4)과 고정측 형판(6)을 결합시키면, 고정측 형판(6)에 설치된 코어핀(8)이 코어핀(8) 삽입부로 삽입되고, 이의 끝단이 벤트홀(9)의 상단에 형성된 록킹부(10)의 홈(11)에 안착되며, 이러한 상태에서 상기 게이트(7)를 통해 성형물을 주입하면 제1도와 같이 긴 보스를 가진 제품(12)이 성형된다.According to the present invention configured as described above, when the movable side template 4 and the fixed side template 6 are coupled as shown in FIG. 1, the core pin 8 installed on the fixed side template 6 is inserted into the core pin 8 insertion portion. The end thereof is seated in the groove 11 of the locking part 10 formed at the upper end of the vent hole 9, and in this state, when the molding is injected through the gate 7, the boss having a long boss as shown in FIG. The product 12 is molded.

상기한 상태에서 상기 제품(12)을 취출하기 위하여 하판(1)의 상부에 설치된 가동측 형판(4)과 고정축 형판(6)을 파팅시키면, 게이트(7)의 말단과 제품(12)이 절단되고, 동시에 코어핀(8)의 상승으로 성형제품(12)만이 성형부(5)에 남게되며, 이때 이젝터(2)를 작동시켜 제품을 취출하게 되는 것으로, 상기 취출작업시 즉 코어핀(8)이 상승될때 벤트홀(9)에 공기를 주입시키게 된다.When the movable side template 4 and the fixed shaft template 6 installed above the lower plate 1 are parted in order to take out the product 12 in the above state, the end of the gate 7 and the product 12 At the same time, only the molded product 12 is left in the molding part 5 due to the rise of the core pin 8, and the ejector 2 is operated to take out the product. When 8) is raised, the air is injected into the vent hole 9.

상기와 같이 함에 따라 제품(12)의 보스부분 표면처리 및 끝단처리가 매끄럽게 되고, 또 성형부(5)에서 쉽게 이형되므로 이의 취출이 용이하게 되며, 상기 벤트홀(9) 상방에 홈(11)을 가진 록킹부(10)를 형성하므로써 코어핀(8)을 제어할 수 있고, 보스의 변형을 방지할 수 있게 된다.As described above, the boss portion surface treatment and the end treatment of the product 12 become smooth, and since the mold portion 5 is easily released from the molding portion 5, the extraction thereof is easy, and the groove 11 above the vent hole 9. By forming the locking portion 10 having a controllable core pin 8, it is possible to prevent deformation of the boss.

이상과 같은 본 고안은 보스의 변형없이 이의 성형 및 취출을 용이하게 할 수 있으며, 특히 성형되는 제품의 이형성이 좋고, 제품의 변형이 없으므로 제품이 매끄럽게 되며, 재 가공을 하지 않아도 되는 점 등의 특징을 지닌 것이다.The present invention as described above can facilitate the molding and take-out thereof without deformation of the boss, in particular, the good releasability of the product to be molded, the product is smooth because there is no deformation of the product, there is no need for reprocessing Will have.
