종래의 사출성형금형의 구조는, 제1도에 도시된 바와 같이, 고정측취부판(1)이 런너 스트리퍼판(2) 및 고정측 형판(3)과 연결되어 고정측을 형성하고, 스프루(22)는 로케이트링(21) 내에 조립되어 고정측취부판(1)에 연결되어 있고, 가동측형판(4)은 차례로 받침판(5), 스페이스블록(6), 상 이젝트판(7), 하 이젝트판(8) 및 가동측 취부판(9)와 연결되어 가동측을 형성하고 있다.In the structure of the conventional injection molding mold, as shown in FIG. 1, the fixed side mounting plate 1 is connected to the runner stripper plate 2 and the fixed side mold plate 3 to form the fixed side, and the sprue (22) is assembled in the locate ring (21) and connected to the fixed side mounting plate (1), and the movable side plate (4) is in turn a supporting plate (5), a space block (6), and an upper ejection plate (7). And the high eject plate 8 and the movable side mounting plate 9 to form the movable side.

이러한 사출성형금형의 사출성형은, 사출기의 노즐(미도시)를 통해 용융수지가 스프루(22)를 통해 고정측형판(3)상의 상코아(13)에 흘러 하코아(14)에 이르러 고정측형판(3)과 가동측형판(4)의 면접촉으로 성형품이 완성된다. 이후 용융수지가 냉각되어 냉각작용이 완료되면 가동측형판(4)이 후퇴되는데, 사출기 취출로드에 의해 하 이젝트판(8)이 전진하고 내부의 이젝트핀에 의해 성형품이 가동측형판(4)에서 분리된다.In the injection molding of the injection molding mold, the molten resin flows through the sprue 22 to the top core 13 on the stationary side plate 3 through the nozzle (not shown) of the injection molding machine, and reaches and fixes the hacoa 14. The molded article is completed by the surface contact between the side plate 3 and the movable side plate 4. After the molten resin is cooled and the cooling operation is completed, the movable side plate 4 is retracted. The eject plate 8 is advanced by the ejector ejection rod, and the molded product is moved from the movable side plate 4 by an ejector pin therein. Are separated.

상기 형편(3)(4)의 면접은 가이드부시(33) 및 가이드 핀(34)에 의해 이루어지고, 이젝트핀의 복원은 리턴핀(28)에 의해 이루어지고 있다.The interviews of the pieces 3 and 4 are made by the guide bush 33 and the guide pin 34, and the restoration of the eject pin is made by the return pin 28.

이와 같이 종래의 사출성형금형에서는 한 금형 코아내에서 하나의 성형품을 생산하므로 전체적으로 교환, 분해, 조립 등이 요구되므로 금형의 제작, 가공, 분해, 조립 및 보관 등에 따라 비용과 시간이 증대되는 문제점이 있었다.As such, conventional injection molding molds produce one molded product in one mold core, and thus require replacement, disassembly, and assembly as a whole. Therefore, cost and time increase due to manufacturing, processing, disassembly, assembly, and storage of the mold. there was.

본 고안은 이러한 종래기술의 문제점을 해결하기 위한 것으로, 기본금형에 코아만의 교화나, 가공 등을 할 수 있어 비용 및 시간을 절감할 수 있는 사출성형금형의 구조의 제공을 목적으로 한다.The present invention is to solve the problems of the prior art, it is an object of the core mold to provide the structure of the injection molding mold that can reduce the cost and time can be re-coated, processed and the like.

상기 목적을 달성하기 위하여, 본 고안의 사출성형금형의 구조는, 고정측형판과, 기동측형판을 구비하는 사출성형금형의 구조에 있어서, 상기 고정측형판상에 상코아를 갖는 상코아금형의 착탈가능하게 조립되고, 상기 가동측형판상에 하코아를 갖는 하 코아금형의 착탈가능하게 조립된 것을 특징으로 한다.In order to achieve the above object, the structure of the injection molding mold of the present invention, in the structure of the injection molding mold having a fixed side plate and a starting side plate, the attachment of the upper core mold having an upper core on the fixed side plate. It is assembled as possible, and the detachable assembly of the ha core mold which has a ha core on the said movable side plate is characterized.

이하, 첨부 도면을 참조하여 본 고안의 사출성형금형의 구조를 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings will be described in detail the structure of the injection molding mold of the present invention.

본 고안의 사출성형금형의 구조는, 제2도에 도시된 바와 같이, 고정측취부판(1)이 런너 스트리퍼판(2) 및 고정측 형판(3)과 연결되어 고정측을 형성하고, 스프루(22)는 고정측취부판(1)에 연결되고 있고, 가동측형판(4)은 차례로 받침판(5), 스페이스블록(6), 상 이젝트판(7), 하 이젝트판(8) 및 가동측 취부판(9)와 연결되어 가동축을 형성하고 있고, 상기 고정측형판(3)상에 상코아(54)를 갖는 상코아 금형(58)이 착탈가능하게 실린더(51)로 조립되고, 상기 가동측형판(4)상에 하코아(53)를 갖는 하 코아금형(59)이 착탈가능하게 조립되어 있다.In the structure of the injection molding mold of the present invention, as shown in FIG. 2, the fixed side mounting plate 1 is connected to the runner stripper plate 2 and the fixed side template 3 to form the fixed side, The base 22 is connected to the fixed side mounting plate 1, and the movable side plate 4 is in turn supported by the support plate 5, the space block 6, the upper ejection plate 7, the high ejection plate 8, and An upper core die 58 having an upper core 54 on the stationary side plate 3 is assembled with a cylinder 51 so as to be connected to the movable side mounting plate 9 to form a movable shaft. A lower core mold 59 having a lower core 53 on the movable side plate 4 is detachably assembled.

한편, 하코아(53)의 성형품을 취출하기 위한 밀핀(55)이 기본금형의 밀핀(56)에 의해 작동되는 이젝트판(60)에 작동하도록 되어 있다.On the other hand, the mill pin 55 for taking out the molded article of the hacoa 53 is operated to the eject plate 60 operated by the mill pin 56 of the basic mold.

이하, 본 고안의 사출성형금형의 구조의 작용을 설명한다.Hereinafter, the operation of the structure of the injection molding mold of the present invention will be described.

이러한 사출성형금형의 사출성형은, 사출기의 노즐(미도시)를 통해 용융수지가 스프루(22)를 통해 고정측정판(3)상의 상 코아 금형(58)의 상코아(54)에 흘러 하코아 금형(59)의 하코아(53)에 이르러 상코아 금형과 하 코아 금형의 면접촉으로 성형품이 완성된다.In the injection molding of the injection molding mold, the molten resin flows through the sprue 22 to the upper core 54 of the upper core mold 58 on the fixed measuring plate 3 through the sprue 22. The molded article is completed by the surface contact of the upper core mold and the lower core mold by reaching the core 53 of the core mold 59.

이후 용융수지가 냉각되어 냉각작용이 완료되면 가동측형판(4)이 후퇴되는데, 사출기 취출로드(57)가 하 이젝트판(8)을 밀고, 하이젝트판(8)의 밀핀(56)이 하코아금형의 하 이젝트판(60)를 밀어 하 이젝트판(60)의 밀핀(55)의 하코아의 성형품을 하코아로 부터 분리하게 된다.After the molten resin is cooled and the cooling operation is completed, the movable side plate 4 is retracted. The ejector ejection rod 57 pushes the high eject plate 8, and the mill pin 56 of the high eject plate 8 is lowered. Pushing the core mold eject plate 60 to separate the molded product of the cocoa of the mill pin 55 of the high eject plate 60 from Hacoa.

이때 가이드핀(52)은 상, 하 코아 금형의 이동결합을 안내하며 맞춤핀 역할을 한다.At this time, the guide pin 52 guides the mobile coupling of the upper and lower core molds and serves as a dowel pin.

이상, 상세히 설명한 바와 같이, 본 고안에 따르면, 본 고안의 사출성형금형의 구조는, 기본금형을 그대로 두고, 코아부분만을 사용할 수 있어, 금형의 제조시, 금형의 교환시, 금형에 수정시에 코아부분만을 제조, 교환, 수정하면 되므로, 조립, 분해, 보관 등에 따른 비용과 시간을 크게 절감할 수 있는 효과가 있다.As described above, according to the present invention, according to the present invention, the structure of the injection molding mold of the present invention can be used only in the core part with the basic mold intact. Since only the core part needs to be manufactured, exchanged, and modified, the cost and time for assembly, disassembly, and storage can be greatly reduced.
