본 고안은 사출금형에 의해 제작하는 전자렌지등의 가전제품의 부품 특히, 턴테이블, V-벨트풀리 등과 같이 보스부를 구비한 제품의 사출 성형 작업에 관한 것으로서, 보스부를 중심으로 회전체의 동심도가 정확히 유지되도록 안출한 아웃써어트 성형용 사출 금형의 소재 고정 장치에 관한 것이다.The present invention relates to the injection molding operation of parts of home appliances such as microwave ovens manufactured by injection molds, particularly products having bosses such as turntables and V-belt pulleys. It relates to a material fixing device of the injection mold for out-assert molding to be held.
종래에는 도면에서 보는 바와같이 프로젝션 용접에 의해 고정된 회전판을 고정 설치할 수 있도록 하기 위하여 가동축형판의 선단부에 평행상태의 고정구를 형성하고, 그 평행 고정구에 회전판을 삽입후 각기 가동몰드 및 고정몰드를 밀착시켜 닫은 상태에서 금형의 캐비티 속으로 액상의 재료를 압입하여 제품을 제작하여 왔는데, 회전판을 고정시킬 때 회전판 중앙에 형성된 삽입공의 크기가 제품의 모델마다 다소 상이하기 때문에, 외경의 변동이 없는 고정구에 회전판을 삽입 설치할 때, 삽입공이 고정구보다 클 경우가 있는데, 이때에는 "A"부 만큼의 틈새가 생김으로 인하여 사출 성형후 취출된 완성 제품의 보스부를 중심으로 회전시킬 경우 "A" 만큼 흔들림이 발생되며, 회전판의 외주의 크기에 비례하여 흔들림의 정도가 더욱 격심해져 제품을 사용할 수 없게 되는 커다란 문제점이 발생하게 되었다.Conventionally, as shown in the drawings, in order to be able to fix and install a fixed rotating plate by projection welding, to form a fastener in parallel to the front end of the movable shaft plate, insert the rotating plate into the parallel fixture and then move the movable mold and the fixed mold, respectively The product has been manufactured by injecting a liquid material into the cavity of the mold in close contact. Since the size of the insertion hole formed in the center of the rotating plate is slightly different for each model of the product when fixing the rotating plate, there is no change in the outer diameter. When inserting the rotating plate into the fixture, the insertion hole may be larger than the fixture. In this case, the gap is created as much as "A", and when it rotates around the boss of the finished product taken out after injection molding, it swings by "A". Is generated, and the degree of shaking becomes more severe in proportion to the size of the outer circumference of the rotating plate. This was a big problem that can not be generated.
따라서, 본 고안을 상기와 같은 문제점을 해결하기 위해, 회전판의 삽입공에 삽입되는 가동축형판의 돌기부에 회전판을 삽입 설치할 때 회전판의 삽입공의 크기가 다소 다를 지라도 그에 관계없이 정확하게 동심도가 맞아지도록 가동축형판의 돌기부의 형상을 경사지게 고정구를 설치하여, 삽입공 크기의 변화에 대처하도록 하여 호환성을 부여한 것으로, 회전체의 보스부의 동심도를 간단하면서도 정확하게 맞추기 위하는데 목적이 있는 것이다.Therefore, in order to solve the problems as described above, when inserting the rotary plate into the projection of the movable shaft plate is inserted into the insertion hole of the rotating plate so that the size of the insertion hole of the rotating plate is slightly different so that the concentricity is exactly matched The inclined shape of the projection part of the movable shaft plate is provided so as to cope with the change of the insertion hole size, thereby providing compatibility, and the purpose is to easily and accurately match the concentricity of the boss part of the rotating body.
이를 첨부도면에 따라서 상세히 설명하면 다음과 같다.This will be described in detail according to the accompanying drawings.
중앙에는 오목부내에 코어핀(23)을 돌출시킨 가동측 코어(22)와 그 외측에 가동측형판(21)이 받침판(24)과 설치판(25) 상에 고정 결합설치된 가동몰드와, 그와 대향작용할 고정몰드가 베이스 상단에 설치되어 작용하는 통상의 아웃써어드 성형용 사출기에 있어서, 가동측형판(21)의 가동측코어(22) 전둘레 외측방에는 전방에 이탈방지편(16)을 구비한 오목부(14)가 형성되고, 외측에 테이퍼측면(12)과 하방에는 상기 오목부(14)내에 이탈방지편(16)을 구비한 오목부(14)가 형성되고, 외측에 테이퍼측면(12)과 하방에는 상기 오목부(14)내에 위치할 프랜지부(13)를 구비한 원통형 고정구(11)가 가동측 코어(21) 외측면에 압축스프링체(15)로서 슬라이딩 자재토록 삽입 설치되는 것이다.In the center, the movable side core 22 which protruded the core pin 23 in the recessed part, and the movable mold in which the movable side plate 21 was fixedly installed on the support plate 24 and the mounting plate 25 at the outer side, In the conventional out third molding injection molding machine, in which a fixed mold to be opposed to the top is installed on the upper end of the base, the release preventing piece 16 is placed in front of the front side of the movable side core 22 of the movable side plate 21. The recessed part 14 provided with the recessed part is formed, The tapered side surface 12 at the outer side and the recessed part 14 provided with the release prevention piece 16 in the said recessed part 14 are formed in the outer side, and the taper is outer side. On the side 12 and below, a cylindrical fixture 11 having a flange portion 13 to be located in the recess 14 is inserted into the spring 21 as a compression spring 15 on the outer side of the movable side core 21. It is installed.
이와 같이 구성된 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.
고정몰드와 가동몰드의 분리로 인하여 금형이 개방되고 이젝터핀(100)이 후퇴하게 되면 회전판(1)은 가동측형판(21)의 전방에 위치한 테이퍼형의 고정구(11)에 삽입하고 각 가동몰드 및 고정몰드를 밀착시켜 닫게되면 고정측코어(200)가 회전판(1)의 후면을 밀어주게 되어 회전판(1) 전면의 삽입공(400)과 경사체의 고정구(11)가 정확하게 동심도를 유지하면서 삽입 고정 되는데 이때, 고정구(11) 후면에 위치한 압축스프링체(15)의 탄성을 부여 받아 고정구(11) 및 회전판(1)에 무리없이 더욱 부드럽고 안정되게 고정이 되며, 고정구(11)의 이탈방지 및 탄성범위를 제한하기 위하여 이탈 방지편(16)이 설치되어 있는 것이다.When the mold is opened and the ejector pin 100 is retracted due to the separation of the fixed mold and the movable mold, the rotating plate 1 is inserted into the tapered fixture 11 located in front of the movable side plate 21 and each movable mold When the fixing mold is in close contact with the fixing mold, the fixing side core 200 pushes the rear surface of the rotating plate 1 such that the insertion hole 400 of the front of the rotating plate 1 and the fixing tool 11 of the inclined body maintain precisely concentricity. In this case, the elastic spring of the compression spring body 15 positioned at the rear of the fixing member 11 is inserted and fixed to the fixing member 11 and the rotating plate 1 more smoothly and stably, and the separation of the fixing member 11 is prevented. And the separation prevention piece 16 is provided to limit the elastic range.
상기와 같이 고정이 완료됨과 동시에 금형이 닫히게 되면서 스프투 게이트(300)를 통해 액체 상태의 재료를 밀어넣어 밀착된 금형의 빈공간으로 속속들이 채우고, 그 재료가 금형내에서 냉각되며 굳어지게 되어 완성제품이 만들어 지는 것이다.When the fixing is completed as described above and the mold is closed, the liquid material is pushed through the soup-to-gate 300 to fill the empty space of the mold in close contact, and the material is cooled and hardened in the mold. This is what is made.
이와같이 작용하는 본 고안은 고정구(11)를 경사지게 형성하여 간단한 조작으로 회전체의 동심도를 충실히 맞출 수 있어 종래의 중심이동에서 오는 문제점을 간단하게 해소하는 특출한 효과가 있는 것이다.The present invention acting as described above has an extraordinary effect of simply forming the fixture 11 inclined to faithfully match the concentricity of the rotating body with a simple operation, thereby easily solving the problems resulting from the conventional center movement.
