본 고안은 세탁기 펄쉐이터(Pulsator) 성형 금형의 성형품 취출 장치에 관한 것으로, 특히 밀핀을 고정하는 핀지지판과 성형기의 이젝터봉이 밀어주도록 된 밀판을 없애고, 밀핀을 슬라이브 파이프 구조로 하여 그 내부에 길이 방향으로 격판을 장설하여 냉각수가 통하도록 하여 제품을 냉각시킬 수 있도록 한 것이다.The present invention relates to a device for taking out a molded article of a washing machine pulsator molding die, and in particular, a pin support plate for fixing a mill pin and an ejector rod for pushing the ejector rod of the molding machine are removed, and the mill pin is a slide pipe structure. The diaphragm is installed in the longitudinal direction to allow the coolant to pass through to cool the product.
종래의 세탁기 펄쉐이터 성형품 취출장치는 상원판과 하원판내에 슬라이드코아 및 하코아, 밀핀지지판, 받침판, 밀판등으로 구성되어 그 구조가 복잡하고 이로 인하여 금형 제작비 또한 고가이며, 또 사용이 매우 불편하고 잔고장이 일어나는 등의 폐단이 있었으며, 특히 별도의 냉각수 순환 장치가 필요하므로 이로 인하여 더욱 복잡한 구조를 형성하게 되는등의 많은 결점이 있었다.Conventional washing machine pearl shader ejection device is composed of slide core and hacoa, mill pin support plate, support plate, mill plate, etc. in the upper plate and the lower plate, the structure is complicated, and the mold manufacturing cost is also expensive and very inconvenient to use. And there was a closed end such as a balance failure, and in particular, because a separate cooling water circulation device is required, there are many defects such as forming a more complex structure.
따라서 본 고안은 상기와 같은 종래의 결점을 감안하여 안출된 것으로 특히 금형의 구성품중 핀지지판 및 밀판을 쓰지 않고도 성형이 용이하고, 또 밀핀내에 격판을 장설하여 냉각수가 통하도록 하므로서 제품 냉각을 시키도록 한 취출 장치를 제공하는데 그 목적이 있는 것으로 이하 첨부된 도면에 의거 상세히 설명하면 다음과 같다.Therefore, the present invention has been devised in view of the above-mentioned drawbacks, and in particular, it is easy to mold without using a pin support plate and a mill plate among the components of the mold, and also to install a diaphragm in the mill pin to allow the cooling water to pass through the product to be cooled. It will be described in detail with reference to the accompanying drawings that the purpose is to provide a take-out device as follows.
하원판(1)에 세탁기 펄쉐이터의 측부를 형성하도록 돈 하코아(2)를 축설하고, 이 하코아(2)의 내부로 내부에 격판(3)를 장설하고, 슬리이브 파이프 구조로 된 밀핀(4)을 삽설하되, 밀핀(4)의 하부에 스프링 탄지턱(5)을 형성하고, 밀핀(4)의 저면에는 기밀유지용 O링(6)을 삽설한 밀핀 받침편(7)을 고착시키고, 상기한 밀핀(4)의 탄지턱(5) 하측에 냉각수 공급관(8)을 장설하여, 이 냉각수 공급관(8)을 통하여 주입된 냉각수가 밀핀(4)의 내부의 일측을 따라 들어가 격판(3)의 타측으로 순환되어 흘러나오게 하였으며, 받침판(9) 하부에 밀핀 가이드봉(10)을 장설하였는데, 이 밀핀 가이드봉(10)의 일측에는 상기한 밀핀(4)의 일측에 장설되는 냉각숨 공급관(8)의 승강 작동이 용이토록 가이드 승강공(11)을 형성하고 밀핀 가이드봉(10)의 내측은 밀핀(4)을 탄지하는 사각코일스프링(12)을 삽설하되, 사각코일스프링(12)의 길이가 매우 길어지고 또 긴 사각코일스프링(12)의 구입이 용이치 않으므로 두 개로 형성하여 중간에 와셔(13)를 삽설하며, 하원판(1)과 받침판(9) 및 하고정판(15)은 사출시 벌어지거나 요동하지 않도록 고정볼트(16)로서 체결 고정하여서된 세탁기 펄쉐이터 성형 금형의 성형품 취출 장치인 것이다.Don Hacoa 2 is built in the lower plate 1 so as to form the side of the washing machine pearl shader, a diaphragm 3 is installed inside the Hacoa 2, and a sleeve pipe structure Insert the pin (4), but the spring tungsten jaw (5) is formed in the lower part of the pin (4), the bottom of the pin (4) is a pin pin support piece (7) in which the O-ring (6) for airtightness is inserted The cooling water supply pipe 8 is installed in the lower side of the carbon jaw 5 of the mil fin 4, and the cooling water injected through the cooling water supply pipe 8 enters along one side of the inside of the mil fin 4 and partitions. Circulated to the other side of (3) and flowed out, and was installed in the bottom of the backing plate (9), the pin pin guide rod 10, the one side of the pin pin guide rod 10, the cooling is installed on one side of the pin (4) Square coil for forming the guide lifting hole (11) to facilitate the lifting operation of the breathing supply pipe (8) and the inside of the mil pin guide rod (10) holding the mil pin (4) Insert the spring 12, but because the length of the rectangular coil spring 12 is very long and it is not easy to purchase a long rectangular coil spring 12 formed into two to insert the washer 13 in the middle, the lower plate (1) and the support plate 9 and the fixed plate 15 is a molded article take-out device of the washing machine pearl shaper molding die which is fastened and fixed as a fixing bolt 16 so as not to open or swing during injection.
미 설명 부호 20은 이젝터봉, 21,21' , 슬라이드코아, 22는 슬라이드 가이드봉, 23은 상원판, 24는 성형품, 26은 다리, 27은 이젝터봉 삽입공 이다.Reference numeral 20 is an ejector rod, 21, 21 ', slide core, 22 is a slide guide rod, 23 is the upper plate, 24 is a molded product, 26 is a leg, 27 is an ejector rod insertion hole.
위와 같이 구성된 본 고안의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above are as follows.
성형품(24) 취출시 형개는 상원판(23)과 하원판(1) 사이에서 되는데, 이때 슬라이드 가이드봉(22)에 의해 슬라이드코아(21)가 외측으로 이송한 후 이어서 하고정판(15)의 이젝터봉 진입공(27)을 통하여 이젝터봉(20)이 인입되면서 밀핀받침편(7)을 밀어주므로서 사각코일 스프링(12)이 압축되면서 밀핀(4)이 진입하게 되므로 성형품(24)이 취출되는 것인데, 이때 냉각수 공급관(6)도 가이드 승강공(11)내에서 밀핀(4)과 같이 승강되는 것이고, 성형시에는 이 냉각수 공급관(8)을 통하여 계속 냉각수가 주입되면서, 주입된 냉각수는 밀핀(4) 내부에 장설된 격판(3)의 일측으로 들어가 격판(3) 상측의 틈새를 통하여 격판(3)의 일측으로 들어가 격판(3) 상측의 틈새를 통하여 격판(3)의 타측으로 순환되는 것이며, 밀핀(4)의 원복은 사각코일 스프링(12)의 복원력에 의해 제위치로 돌아오는 것이다.When the molded article 24 is taken out, the mold opening is made between the upper plate 23 and the lower plate 1, wherein the slide core 21 is transferred to the outside by the slide guide rod 22, and then the fixing plate 15 is removed. As the ejector rod 20 is pushed in through the ejector rod entry hole 27, the push pin support piece 7 is pushed in, and thus the square pin spring 12 is compressed, so that the mill pin 4 enters the molded article 24. In this case, the cooling water supply pipe 6 is also elevated in the guide lifting hole 11, such as the mill pin (4), and during the molding, while the cooling water is continuously injected through the cooling water supply pipe (8), the injected cooling water is a mill pin (4) enters one side of the diaphragm (3) installed therein and enters one side of the diaphragm (3) through the gap on the upper side of the diaphragm (3) and is circulated to the other side of the diaphragm (3) through the diaphragm on the upper side of the diaphragm (3). The original pin of the mill pin 4 is in position by the restoring force of the square coil spring 12. It will come back.
상술한 바와 같이 본 고안은 냉각수가 공급되도록 된 밀핀(4)이 이젝터봉(20)에 의해 바로 진입토록 하므로서 별도로 밀판 지지판 및 밀판을 제작할 필요가 없고, 이로 인한 금형제작 공정 및 비용이 대폭 절감되는 것이며, 특히 냉각수가 밀핀(4) 내부로 순환되게 함으로서 냉각효과 또한 매우 우수한 것으로 구조가 간단하여 고정이 전무한 등의 잇점이 있는 매우 유용한 고안인 것이다.As described above, the present invention does not need to separately manufacture the plate support plate and plate because the mill pin 4 to be supplied with the coolant is directly entered by the ejector rod 20, thereby greatly reducing the mold manufacturing process and cost. In particular, the cooling water is also very good by allowing the cooling water to circulate inside the mill pin (4) is a very useful design with the advantage of simple structure and no fixing.
