본 고안은 사출 금형에 있어서 원형을 가진 성형품에 제품의 특성상 파팅라인(Parting line)이 있으면 안될 때에 슬라이드 코어를 이용하여 제품을 안전하게 취출시킬 수 있는 사출 금형의 슬라이드 코어를 이용한 자동 취출장치에 관한 것이다.The present invention relates to an automatic take-out device using a slide core of an injection mold that can safely take out the product by using a slide core when the molded article having a circular shape in the injection mold should not have a parting line. .
종래의 경우에는 취출하는 방법이 한정되어 있어서 파팅 라인이 없는 제품을 취출하는데 있어 에젝터를 사용하였기 때문에 제품을 안전하게 취출할 수 없어 품질을 저하시키는 원인이 되었으므로 이들 해결하기 위해 여러 가지 방법들이 사용되어 왔으나 이들은 구조가 복잡할 뿐 아니라 효율적으로 성형품을 취출할 수가 없었던 결점이 있었다.In the conventional case, since the ejection method is limited and the ejector is used to take out the product without the parting line, the product cannot be safely taken out, which causes the quality to be deteriorated. However, they have the drawback that they were not only complicated in structure but also could not take out molded products efficiently.
본 고안은 이와 같은 종래의 결점을 해소시키기 위하여 안출된 것으로서 첨부된 도면에 의하여 그 구성과 작용 효과를 상세히 설명하면 다음과 같다.The present invention is devised to solve such a conventional drawback and the construction and operation effects will be described in detail by the accompanying drawings as follows.
상고정판(1)에 런너(2)를 장착하고 하고정판(3)상면에는 다리(4)와 지지편(5)이 볼트(6)로 체결된 가동축형판(7)을 장착시키고 지지편(5")이 볼트(6')로 체결된 상부 형판(8)의 상면에는 스트리퍼판(9)에 장착된 앵글러핀(10)이 삽입될 홈을 내설시키고 연마편(11)을 고정시킨 슬라이드 코어(12)를 좌, 우측에 장착시키고 슬라이드 코어 홀더(13)를 볼트(6")로 체결시켰으며 또한, 가동축형판(7)의 상부에는 연마편(11')을 설치하고 앵글러핀(10')이 작동될 안내홈을 기존의 앵글러핀(10)의 홈보다 크게 형성시킨 슬라이드 코어(12')를 좌, 우측에 내장시키고 슬라이드 코어홀더(13')를 볼트(6")에 의해서 체결시킨 구성으로써 미설명 부호 14는 성형품인 것이다.The runner 2 is mounted on the upper fixing plate 1, and the movable shaft plate 7 on which the legs 4 and the support pieces 5 are fastened by bolts 6 is mounted on the fixing plate 3 upper surface. A slide core in which a groove into which an angler pin 10 mounted on a stripper plate 9 is inserted is inserted into the upper surface of the upper template 8 to which the bolt 6 'is fastened by the bolt 6', and the polishing piece 11 is fixed. (12) is mounted on the left and right sides, and the slide core holder 13 is fastened by bolts 6 ", and on the upper side of the movable shaft plate 7, an abrasive piece 11 'is installed and an angler pin 10 The slide core 12 'is formed on the left and right sides of the guide groove to which the') is operated to be larger than the groove of the conventional angler pin 10, and the slide core holder 13 'is fastened by the bolt 6 ". As described above, reference numeral 14 denotes a molded article.
이와 같이 구성된 본 고안의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effect of the present invention configured in this way in detail as follows.
제1a도에서 보는 바와 같이, 전체적으로 결합된 상태에서 런너(2)에 용융상태의 성형물을 투입시켜 임의의 성형이 완료된 상태에서 상부 형판(8)과 스트리퍼판(9)사이에 내장시킨 스프링의 탄성력에 의해서 앵글러핀(10)을 경사지게 좌, 우측으로 고정시키고 스트리퍼판(9)을 장착시킨 상고정판(1)이 상향 이동되며 이때 런너(2)는 제품에서 분리되고 동시에 슬라이드 코어(12)에 형성된 안내홈에 삽입된 앵글러핀(10)이 경사면과 접촉되면서 상부형판(8)의 상면에 형성시킨 일정거리의 공간만큼 슬라이드코어(12)를 제품의 언더컷 정도에 따라 좌, 우측으로 진행시키고 슬라이드 코어(12)의 진행거리를 유지해주는 지지편(5')에 의해 정지하게 되어 도면 제1(b)도에서와 같이 1차 언더컷이 이루어지며 이때, 스트리퍼판(9)과 슬라이드 코어 홀더(13)에는 일정거리를 잡아주는 고리 장치가 장착되어 있으며 슬라이드 코어 홀더(13)는 앵글러핀(10')이 장착된 상부 형판(8)에 볼트(6")로 고정되어 있어서 계속적으로 스트리퍼판(9)을 상향 이동시키므로써 상부형판(8)은 제품에서 완전 이탈되고 슬라이드코어(12')에 형성된 앵글러핀(10')과 안내홈은 앵글러핀(10) 안내홈보다 크게 형성되어 있어 앵글러핀(10')과 안내홈과 공간을 형성시키므로 슬라이드 코어(12')가 좌, 우측에서 제품의 밑부분에 형성된 탬 성형부를 잡아주고 앵글러핀(10')이 일정거리 만큼 이동되므로써 슬라이드 코어(12')에 형성된 앵글러핀 안내홈의 경사면 윗부분과 접속되면서 가동축 형판(7)의 상면에 형성된 공간만큼 슬라이드 코어(12')를 제품의 언더컷 정도에 따라 좌, 우측으로 진행시키어 최종적으로 성형품이 안전하게 자동 취출되는 것이다.As shown in FIG. 1A, the elastic force of the spring embedded between the upper template 8 and the stripper plate 9 in a state where any molding is completed by putting the molten molding product into the runner 2 in the state of being fully engaged. By fixing the angler pin 10 to the left and right to be inclined by the top and the upper fixing plate (1) equipped with the stripper plate (9) is moved upwards, wherein the runner (2) is separated from the product and at the same time formed on the slide core (12) As the angler pin 10 inserted into the guide groove is in contact with the inclined surface, the slide core 12 advances to the left and right sides according to the degree of undercut of the product by the space of a predetermined distance formed on the upper surface of the upper plate 8. It stops by the support piece 5 'which maintains the travel distance of 12, and the first undercut is made as shown in FIG. 1 (b), at this time, the stripper plate 9 and the slide core holder 13 A certain distance The azu is equipped with a ring device and the slide core holder 13 is fixed to the upper template 8 on which the angler pin 10 'is mounted with a bolt 6 "to continuously move the stripper plate 9 upwards. The upper upper plate 8 is completely separated from the product, and the angler pin 10 'and the guide groove formed in the slide core 12' are larger than the angler pin 10 guide groove, so the angler pin 10 'and the guide groove are formed. Angular pin formed on the slide core 12 'is formed by forming the grooves and the space, so that the slide core 12' is held at the bottom of the product at the left and right sides, and the angler pin 10 'is moved by a certain distance. The slide core 12 ′ is advanced left and right according to the undercut degree of the product as much as the space formed on the upper surface of the movable shaft template 7 while being connected to the upper portion of the inclined surface of the guide groove, and finally the molded product is automatically taken out safely.
따라서, 상기의 동작을 갖는 자동 취출장치는 제품의 외관에 파팅라인이 없이 성형품을 안전하게 취출시킬 수 있으므로 제품의 품질을 향상시킬 뿐 아니라 원형제품에 있어서 작동이 용이하며 에젝트를 사용하지 않기 때문에 금형의 원가를 절감시키는 효과가 있는 것이다.Therefore, the automatic take-out apparatus having the above operation can safely take out the molded article without the parting line on the exterior of the product, thereby improving the quality of the product as well as making it easy to operate in the circular product and not using the eject mold. It is effective to reduce the cost.
