본 고안은 사출성형기의 관한 것으로서, 특히 긴 용기의 사출 성형시에 제품에 손상이 가거나 금형이 파손되는 것을 방지하도록 하는 사출성형기의 취출장치에 관한 것이다.The present invention relates to an injection molding machine, and more particularly, to an apparatus for taking out an injection molding machine to prevent damage to a product or damage to a mold during injection molding of a long container.
종래 취출장치를 제 1 도에 의해 설명한다.The conventional extraction apparatus will be described with reference to FIG.
구동장치에 의해 상·하 동작되는 받침판(1)과, 상기 받침판(1)의 상부에 접촉되며 일측에 밀핀(3)이 고정되어 있는 고정판(2)과 상기 밀핀(3)에 연결되어 성형제품(7)을 취출시켜주는 스프리퍼 플레이트(4)와, 상기 스트리퍼 플레이트(4)에 의해서 동작되며 성형제품(7)을 성형시켜 주는 성형틀(6)과, 상기 성형틀(6)이 성형제품(7)과의 밀착된 상태에 있을 때 성형제품(7)의 취출이 용이하도록 하기 위해서 밀착된 부분에 압축공기를 주입시켜주는 압축공(5)이 구성되었다.A molded product connected to the support plate 1 which is operated up and down by a driving device, a fixed plate 2 which is in contact with the upper part of the support plate 1, and a pin 3 is fixed at one side thereof, and the mill pin 3. (7) a sputter plate (4) for taking out, a molding mold (6) operated by the stripper plate (4) to mold the molded product (7), and the molding mold (6) is a molded product In order to facilitate taking out of the molded product 7 when it is in close contact with (7), a compressed hole 5 for injecting compressed air into the close contact portion is configured.
이와 같이 구성된 취출장치의 작용을 제 1 도에 의거 설명한다.The operation of the take-out device configured as described above will be described based on FIG.
핫팁(도면에 도시되지 않음)에서 뿜어져 나온 액체상태의 플라스틱이 성형틀(6) 내부로 들어오면서 사출성형이 이루어진다.The injection-molding takes place as the liquid plastic spouted from the hot tip (not shown) enters the mold 6.
그리고 성형된 성형제품(7)을 성형틀(6)에서 취출시키기 위해서 구동장치(도시되지 않음)에 의해서 동력을 받아 작동하는 고정판(2)이 움직이며, 이 고정판(2)에 고정 되어져 있는 밀핀(3)이 상향 동작되면서 스트리퍼 플레이트(4)를 상향으로 밀어올리게 되어 취출이 행하여 지는 것이다.Then, in order to take out the molded product 7 from the molding die 6, a fixed plate 2 which is driven by a driving device (not shown) is moved, and the pin is fixed to the fixed plate 2. As 3 is operated upward, the stripper plate 4 is pushed upward, and the extraction is performed.
이때, 성형틀(6)과 성형제품(7)간에는 사출성형시 강한 밀착력을 받아서 진공상태에 있기 때문에 압축공(5)을 통해서 강한 압축공기를 주입시켜 주어야 취출이 용이하게 행하여 진다.At this time, since the injection mold 6 and the molded product 7 is in a vacuum state by receiving a strong adhesion during injection molding, strong compressed air must be injected through the compression hole 5 to be easily taken out.
그런, 깊이가 깊고 외경이 작은 성형제품의 경우 압축공(5)을 통한 압축공기의 주입에는 한계가 있으므로 성형제품의 취출이 어려웠고 구동장치의 강한 상향력을 받는 스트리퍼 플레이트의 파손으로 인해 성형제품 표면에 흠이 발생하기 쉽고 밀핀의 처짐으로 인해 성형틀 피로가 발생되어 생산성에 문제점이 발생되었다.In the case of a molded product having a deep depth and a small outer diameter, the injection of compressed air through the compression hole 5 is limited, so that the molded product is difficult to take out, and the molded product surface is damaged due to breakage of the stripper plate subjected to the strong upward force of the driving device. It is easy to generate a flaw in the mold due to the deflection of the mill pin caused a problem in productivity.
본 고안은 이러한 문제점을 감안한 것으로서, 금형틀을 벌려주는 실린더의 작동과 동시에 성형제품을 밀어 주도록 상·하 동작하는 취출공이에 의해서 깊이가 깊고 외경이 작은 제품의 경우에도 쉽게 성형틀에서 분리해주도록 하는 취출장치를 제공함하는데 목적이 있다.The present invention has been made in view of the above problems, and it is easy to separate a mold from a mold having a deep depth and a small outer diameter by a blow hole that moves up and down to push the molded product at the same time as the cylinder opening the mold mold. It is an object to provide a take-out apparatus.
본 고안 사출성형기 추출장치의 구성을 제 2 도 및 제 3 도에 의해 설명한다.The construction of the injection molding machine extracting device of the present invention will be described with reference to FIGS. 2 and 3.
금형틀(108)을 벌려주도록 구동력을 제공하는 구동부와, 상기 구동부가 작동됨과 동시에 회동하므로써 성형제품(110)이 금형틀(108)에서 이탈되도록 해주는 상·하 분리부와, 상기 상·하 분리부가 동작되어 성형제품(110)을 이탈시킬 때 공기가 유통되도록 금형틀(108)에 형성된 통기공(109)으로 구성된다.A driving unit providing a driving force to open the mold mold 108, an upper / lower separating portion allowing the molded product 110 to be detached from the mold mold 108 by being rotated at the same time as the driving unit is operated, and the upper and lower separating parts It is composed of a vent hole 109 formed in the mold frame 108 so that the air flows when the additional operation is to leave the molded product 110.
그리고 구동부는 구동력을 주는 실린더(101)와, 상기 실린더(101)의 일측에 연결되고 타측은 금형틀(108)에 연결 구동력을 전달하는 슬라이드 코어(102)로 구성된다.And the drive unit is composed of a cylinder 101 for giving a driving force, the slide core 102 is connected to one side of the cylinder 101 and the other side transmits the driving force to the mold frame (108).
이때 실린더(101)는 유압에 의해서 작동되도록 구성된다.At this time, the cylinder 101 is configured to be operated by hydraulic pressure.
그리고 슬라이드 코어(102)는 상기 상·하 분리부와 접촉되는 부분이 경사지도록 형성되어 슬라이드 코어(102)가 수평 작동됨과 동시에 상·하 분리부가 회동되도록 해주는 슬라이드 면(102')으로 구성된다.The slide core 102 is formed of a slide surface 102 ′ which is formed such that a portion in contact with the upper and lower separation parts is inclined so that the slide core 102 is horizontally operated and the upper and lower separation parts are rotated.
그리고 상·하 분리부는 상기 슬라이트 면(102')에 접촉되어서 상·하 동작을 하므로써 성형제품(11)을 이탈시키는 취출공이(103)와 상기 취출공이(103)가 회동되도록 캐비티 코어(107)에 고정 형성된 고정핀(104)과 상기 취출공이(103)가 회동된 상태에서 원위치로 복귀되도록 탄성력을 주는 탄성부재(105)로 구성된다.In addition, the upper and lower separators contact the slit surface 102 ′ to perform the up / down operation so that the ejection hole 103 and the ejection hole 103 for leaving the molded product 11 are rotated so that the cavity core 107 rotates. It is composed of a fixing pin 104 and fixed to the elastic member 105 to give an elastic force to return to the original position in the ejected hole 103 is rotated state.
미설명 부호 106은 액상의 플라스틱을 금형틀(108) 내부로 주입시키는 핫팁이다.Reference numeral 106 is a hot tip for injecting the liquid plastic into the mold (108).
본 고안 사출성형기 취출장치의 작용, 효과를 제 2 도 및 제 3 도에 의거해서 설명한다.The operation and effect of the present invention injection molding machine ejection device will be described based on FIG. 2 and FIG.
핫팁(106)을 통하여 금형틀(108)내부로 액체상태의 플라스틱을 주입시키면 성형이 이루어진다.Molding is performed by injecting liquid plastic into the mold 108 through the hot tip 106.
이때 성형제품(110)을 취출시키기 위해서 실린더(101)에 유압을 줘서 작동시키면 슬라이더 코어(102)가 우측방향으로 작동되고 슬라이드 코어(102)에 연결되어 있는 금형틀(108)이 벌어지면서 통기공(109)을 통하여 공기가 유입되면 성형제품(110)의 밀착상태는 해소된다.At this time, when the cylinder 101 is operated by applying hydraulic pressure to take out the molded product 110, the slider core 102 is operated in the right direction, and the mold frame 108 connected to the slide core 102 is opened to vent holes. When the air flows through the 109, the close contact state of the molded product 110 is eliminated.
이때 슬라이드 면(102')에 접촉되어 있는 취출공이(103)의 일단은 슬라이드 면(102')을 따라서 미끄러지듯이 올라가게 되고 금형틀(108)에서 원활히 이탈되도록 취출공이(103)의 타단은 성형제품(110)을 하측으로 밀어준다.At this time, one end of the blow hole 103 in contact with the slide surface 102 'is slid up along the slide surface 102' and the other end of the blow hole 103 is molded so as to be separated from the mold frame 108 smoothly. Push the product 110 downward.
그리고 성형제품(110)이 완전히 이탈된 후 실린더(101)에 의해서 슬라이드 코어(102)는 좌측으로 이동하게 되고 탄성부재(105)에 의해서 탄성력을 받는 취출공이(103)는 슬라이드 면(103')을 따라 미끄러져 내려오면서 원상태로 되돌아오게 되는 것이다.After the molded product 110 is completely removed, the slide core 102 is moved to the left side by the cylinder 101, and the ejection hole 103 which is elastically received by the elastic member 105 is the slide surface 103 ′. Sliding down along the way will be back to its original state.
이와 같이 과정은 반복적으로 가동하게 되는 것이다.In this way, the process is operated repeatedly.
따라서 종래의 이탈이 어려웠던 성형제품을 금형틀에서 원활히 이탈시켜 주므로써 다양한 금형틀의 제작이 용이하고 성형 사이클 시간을 줄일 수 있다.Therefore, it is easy to manufacture a variety of mold molds by reducing the molded product that was difficult to remove the mold from the mold frame can be easily reduced the molding cycle time.
그리고, 취출공이에 의해서 취출이 확실히 되도록 함으로써 성형제품에서 발생되는 흠을 없애주고 종래의 금형이 파손되는 것을 방지하도록 해준다.In addition, it is possible to make sure that the ejection is made by the ejection hole, thereby eliminating the flaw generated in the molded product and preventing the conventional mold from being broken.
