본 고안은 용기와 같은 반밀폐 형상의 제품을 성형하기 위한 사출금형의 에어공급장치에 관한 것으로, 특히 콤프레서 등 별도의 기계를 사용하지 않고 금형 자체의 개폐동작을 이용하여 금형 내부로 에어를 공급할 수 있도록 한 것이다.The present invention relates to an air supply apparatus of an injection mold for molding a semi-hermetic product such as a container, and in particular, it is possible to supply air into the mold by using the opening and closing operation of the mold itself without using a separate machine such as a compressor. It would be.
일반적으로 용기와 같이 반밀폐형상으로 된 제품을 성형하는 사출금형은 제품의 취출시 제품의 내측면과 코어 사이에 진공 현상이 발생하게 되고 이러한 상태에서 제품을 그대로 취출하는 경우 파손의 우려가 많기 때문에 취출시 금형내부(성형품과 코어사이)로 에어를 공급하여 제품의 파손을 방지하고 있다.In general, an injection mold for molding a product in a semi-hermetic shape, such as a container, may have a vacuum phenomenon between the inner surface of the product and the core when the product is taken out. When taking out, air is supplied to the inside of the mold (between the molded product and the core) to prevent damage to the product.
금형내부로 에어를 공급하기 위한 종래의 장치, 예를들어 제2도에 도시한 바와같은 장치는 코어(3)의 내부에 에어밸브(6)를 스프링(7)으로 탄력 설치하고 에어통로(8)의 입구 부분에는 콤프레서를 연결하여 제품의 성형후 금형이 열리면 이젝트핀에 의해 제품이 취출됨과 동시에 에어밸브(6)를 통해 에어가 공급되도록 하였다.A conventional apparatus for supplying air into the mold, for example, as shown in FIG. 2, has an air valve 6 installed in the core 3 with a spring 7 and an air passage 8 Compressor was connected to the inlet of the product to open the mold after the molding of the product, and the product was ejected by the eject pin and air was supplied through the air valve (6).
그러나 이러한 종래의 장치는 별도의 콤프레서에 의해 에어를 공급하는 구조이어서 콤프레서가 설치되어 있지 않은 장소에서는 성형작업이 불가능하고 에어를 공급하는 공정이 추가되어 작업시간(금형의 사이클타임)이 길어지게 되며 금형의 개폐에 따라 주기적으로 에어를 공급하기 위해서는 금형에 별도의 센서를 부착해 주어야 하므로 부수적인 설비가 필요하게 되는 등의 문제점이 있었다.However, such a conventional device is a structure in which air is supplied by a separate compressor, so that the molding operation is not possible in a place where the compressor is not installed, and the process of supplying air is added to increase the working time (mould cycle time). In order to periodically supply air in accordance with the opening and closing of the mold, a separate sensor needs to be attached to the mold, thereby requiring additional equipment.
본 고안은 종래의 장치가 지닌 이와같은 문제점을 해소하기 위한 것으로 금형의 일측에 압축실린더를 설치하여 이 압축실린더가 금형의 개폐에 따라 연동하면서 금형 내부로 에어를 공급할 수 있도록 한것인바, 이를 첨부된 도면 제1도에 의해 더욱 상세히 설명하면 다음과 같다.The present invention is to solve such problems with the conventional apparatus, and installed a compression cylinder on one side of the mold to allow the compressed cylinder to supply air into the mold while interlocking with the opening and closing of the mold. Referring to Figure 1 in more detail as follows.
고정측설치판(1), 고정측형판(2), 코어(3), 가동측설치판(4), 가동측형판(5) 등으로 구성된 사출금형의 코어(3) 내부에 에어밸브(6)를 스프링(7)으로 탄력 설치하고 가동측형판(5)에는 에어통로(8)를 형성한 것에 있어서, 고정측형판(2)과 가동측설치판(4)에 각각 브라켓(9)(10)을 고정하여 이들 브라켓(9)(10) 사이에 압축실린더(11)를 설치함과 함께 피스턴(12)과 연결된 피스턴 롯드(13)를 브라켓(9)에 고정하고 롯드측헤드(14)에 형성된 유입공(14a)과 배출공(14b)의 외측에는 각각 일방향 첵크밸브(15)(16)를 설치하여 금형의 개폐에 따라 피스턴(12)이 왕복운동을 하면서 에어통로(8)로 에어를 공급할 수 있게 한 것이다.An air valve 6 inside the core 3 of the injection mold comprising the fixed side mounting plate 1, the fixed side plate 2, the core 3, the movable side mounting plate 4, the movable side plate 5, and the like. ) Is elastically installed with a spring (7) and the air side path (8) is formed on the movable side plate (5), the bracket (9) (10) on the fixed side plate (2) and the movable side mounting plate (4), respectively. ), The compression cylinder 11 is installed between these brackets 9 and 10, and the piston rod 13 connected to the piston 12 is fixed to the bracket 9, and the rod side head 14 One-way check valves 15 and 16 are provided on the outside of the formed inlet 14a and the outlet 14b, respectively, so that the piston 12 reciprocates in accordance with the opening and closing of the mold, thereby introducing air into the air passage 8. It is possible to supply.
도면중 미설명 부호 17은 압축실린더(11) 하방에 형성된 구멍, 18은 첵크밸브(16)와 에어통로(8) 입구부 사이에 연결된 튜브이다.In the figure, reference numeral 17 denotes a hole formed below the compression cylinder 11, and 18 denotes a tube connected between the check valve 16 and the air passage 8 inlet.
이와같이 구성된 본 고안은 금형이 닫혀진 상태에서는 제1도와 같이 압축실린더(11) 내의 피스턴(12)이 최하방에 위치하여 있다가 제품의 성형이 완료된 후 금형이 열리면 에어통로(8)에 자동적으로 에어가 공급되어 제품을 취출하게 된다.According to the present invention configured as described above, the piston 12 in the compression cylinder 11 is positioned at the lowermost position as shown in FIG. 1 in the closed state of the mold, and then air is automatically supplied to the air passage 8 when the mold is opened after the molding of the product is completed. Is supplied to take out the product.
즉, 성형 완료후 금형이 열리면 가동측설치판(4)이 가동측형판(5)과 함께 후퇴하게 되는데, 고정측형판(2)과 가동측설치판(4)에 고정된 브라켓(9)(10) 사이에는 압축실린더(11)가 설치되어 있고 이 압축실린더(11)의 피스턴롯드(13)는 브라켓(9)에 고정되어 있으므로 가동측설치판(4)의 후퇴에 따라 압축실린더(11)의 내용적 "V"가 작아지면서 압축실린더(11) 내의 공기가 압축되며, 압축된 공기는 롯드측헤드(14)에 형성된 배출공(14b)과 첵크밸브(16) 및 튜브(18)를 통해 에어통로(8)로 공급되어 에어밸브(6)를 작동시키게 되는 것이다.That is, when the mold is opened after the molding is completed, the movable side mounting plate 4 is retracted together with the movable side mold plate 5, and the bracket 9 fixed to the stationary side plate 2 and the movable side mounting plate 4 ( A compression cylinder 11 is provided between the cylinders 10 and the piston rod 13 of the compression cylinder 11 is fixed to the bracket 9 so that the compression cylinder 11 is retracted as the movable side mounting plate 4 is retracted. The air in the compression cylinder 11 is compressed as the content "V" of the air is reduced, and the compressed air is discharged through the discharge hole 14b formed in the rod side head 14, the check valve 16, and the tube 18. It is supplied to the air passage (8) to operate the air valve (6).
또, 성형품의 취출이 완료된 후 금형이 닫히면 전술한 바와는 반대로 가동측설치판(4)의 전진에 따라 압축실린더(11)의 내용적 "V"가 커지면서 첵크밸브(15)와 유입공(14a)을 통해 압축실린더(11) 내부로 공기가 유입되고 피스턴(12) 하방의 공기는 압축실린더(11) 하방에 형성된 구멍(17)으로 빠져나가 제1도와 같은 상태로 환원되는데, 배출공(14b)과 유입공(14a)의 외측에 설치된 각 첵크밸브(16)(15)는 일방향 밸브이어서 압축실린더(11)의 내용적 "V"의 변화에 따라 압축실린더(11) 내의 공기가 배출공(14b)으로 배출될 때에는 첵크밸브(16)만 열리고 유입공(14a)으로 공기가 유입될 때에는 첵크밸브(15)만 열리게 되므로 공기의 역류현상은 일어나지 않는다.In addition, if the mold is closed after the ejection of the molded article is completed, the check valve 11 and the inlet hole 14a become larger as the internal volume of the compression cylinder 11 increases as the movable side mounting plate 4 moves forward. Air is introduced into the compression cylinder (11) through the air and the air below the piston (12) exits the hole (17) formed below the compression cylinder (11) and is reduced to the state as shown in FIG. 1, the discharge hole (14b) ) And each of the check valves 16 and 15 provided at the outside of the inlet hole 14a are one-way valves so that the air in the compression cylinder 11 is discharged in accordance with the change in the volume "V" of the compression cylinder 11. 14b), only the check valve 16 is opened and when the air is introduced into the inlet hole 14a, only the check valve 15 is opened so that no backflow of air occurs.
이상에서와 같이 본 고안은 금형 일측에 설치된 압축실린더(11)가 금형의 개폐동작에 따라 연동하면서 제품의 취출시마다 자동적으로 에어를 공급하게 되어 있으므로 에어의 공급을 위한 에어콤프레서 등의 부수적인 설비가 불필요해지며, 에어공급을 위한 별도의 시간이 필요하지 않아 금형의 사이클타임이 단축되므로 생산성의 향상을 가져오는 효과가 있다.As described above, the present invention is designed to supply air automatically every time the product is taken out while the compression cylinder 11 installed on one side of the mold is interlocked according to the opening / closing operation of the mold, thereby providing additional equipment such as an air compressor for supplying air. It is unnecessary, and the cycle time of the mold is shortened because no time for air supply is required, resulting in an improvement in productivity.
