본 고안은 다층 캐비티 사출 금형에 관한 것으로, 특히 제품 형상의 홈이 상,하부면에 가공되어 있는 중간형틀을 상,하형틀 사이에 설치하여 상하층에서 동시에 제품이 성형되도록 하므로서 짧은 시간내에 많은 양의 제품을 사출할 수 있도록 한 것에 관한 것이다.The present invention relates to a multi-layer cavity injection mold, and in particular, an intermediate mold in which the groove of the product shape is processed on the upper and lower surfaces is installed between the upper and lower molds so that the product is molded at the same time in the upper and lower layers. It is about making it possible to inject the product of.

종래에는 상,하형틀을 일개조로 하는 금형의 상,하부판에만 제품 형상의 홈을 가공하여 상,하부판에 가공되어 일치되는 홈의 수 만큼 제품을 사출하여 왔었다.Conventionally, only the upper and lower plates of a mold having the upper and lower molds are processed to process the grooves of the product shape, and the products have been injected into the upper and lower plates by the number of matching grooves.

그런데 많은 수의 제품을 사출하기 위하여 상,하부판의 면에 각각 제품형상의 홈을 가공하고자할 때에는 상하부판의 면적이 커져야하고 이에 따라 자동적으로 금형 크기가 커져야하므로 대형 사출기로 사출하여야 하는 불합리한 문제점이 발생하기 또한 가공하기 위하여 운반하는데 힘이 많이들 뿐 아니라 보관상에도 넓은 면적을 차지해야 하는 문제점이 있었다.However, in order to process the product shape grooves on the upper and lower surfaces of the upper and lower plates in order to inject a large number of products, the area of the upper and lower plates must be large, and accordingly, the mold size must be automatically increased, thereby causing an unreasonable problem of injection into a large injection molding machine. There is a problem that it takes a lot of effort to transport to generate and process, as well as occupy a large area in storage.

본 고안은 상술한 문제점을 해소하기 위해 제안된 것으로 작은 사이즈의 금형에서도 많은 수의 제품을 사출할 수 있도록 한 다층 캐비티 사출 금형을 제공하는데 목적이 있다.The present invention has been proposed to solve the above-mentioned problems, and an object of the present invention is to provide a multi-layer cavity injection mold capable of injecting a large number of products even in a small mold.

상기 목적을 달성하기 위한 본 고안은 중간형틀의 상부면에는 상형틀의 하부면에 가공된 제품 형상의 홈과 일치되도록 가공하고, 중간형틀의 하부면에는 하형틀 상부면에 가공된 제품의 형상의 홈과 서로 일치하도록 가공한 중간형틀을 상,하형틀 사이에 설치한 다음 중간형틀과 하형틀의 양측면에 삼단고리를 부착하여 삼단봉을 설치하므로서 목적은 달성된다.The present invention for achieving the above object is processed to match the groove of the product shape processed on the lower surface of the upper mold on the upper surface of the intermediate mold, the lower surface of the upper mold of the shape of the product processed on the upper mold The purpose is achieved by installing the intermediate mold machined to match the grooves between the upper and lower molds, and then attaching the three-stage ring to both sides of the intermediate mold and the lower mold.

이하, 본 고안의 바람직한 구성 및 작용·효과를 첨부된 도면에 따라서 상세히 설명한다.Hereinafter, the preferred configuration, operation, and effects of the present invention will be described in detail with reference to the accompanying drawings.

도1은 본 고안의 분리 사시도이고, 도2는 본 고안에 의해 제품이 사출되는 상태를 종방향으로 절단하여 나타낸 상태도이다.Figure 1 is an exploded perspective view of the present invention, Figure 2 is a state diagram showing the state in which the product is injected by the present invention in the longitudinal direction.

도1에 의하면 취부판(1)과 상,하부판(2)(2a)으로 형성된 상,하형틀에 있어서, 상,하면에 제품형상의 홈(6)(6a)이 가공된 중간형틀(4)을 상,하형틀(3)(3a) 사이에 설치하되, 성형틀(3)의 하부면과 중간형틀(4)의 상부면에 제품형상의 홈(6')(6)이 서로 대칭되도록 가공하고, 중간형틀(4)의 하부면과 하형틀(3a)의 상부면에도 제품 형상의 홈(6a)(6a')을 서로 대칭되도록 가공한 다음 중간형틀(4)과 하형틀(3a)의 양측면에 구멍(5)이 형성된 삼단고리(7)를 설치하여 삼단봉(8)을 각각 구멍(5)으로 관통하여 연결되게 설치한 구성이다.Referring to Fig. 1, in the upper and lower molds formed by the mounting plate 1 and the upper and lower plates 2 and 2a, an intermediate mold 4 in which grooves 6 and 6a of product shapes are processed on the upper and lower surfaces. It is installed between the upper and lower molds (3) (3a), the processing grooves 6 ', 6 in the shape of the product on the lower surface of the mold 3 and the upper surface of the intermediate mold (4) The grooves 6a and 6a 'of the product shape are also symmetrically processed on the lower surface of the intermediate mold 4 and the upper surface of the lower mold 3a, and then the intermediate mold 4 and the lower mold 3a are A three-stage ring (7) having holes (5) formed on both sides is installed to connect the three-stage rod (8) through the holes (5), respectively.

한편, 중간형틀(4)의 중심부에 구멍(5a)을 천공하여 노즐(9)에서 분사되는 수지를 상형틀(3)의 구멍(5b)을 통과한 다음 하형틀(3a)의 런너홈(5c)에까지 도달하게 한 구성이고, 또한 이젝트 핀(11)이 상측 제품과 하측 제품에 간섭을 받지 않도록 서로 다른 형태로 런너를 위치토록함과 동시에 제품 위치도 서로 다른 위치에 오도록 형성한 구성이다.On the other hand, the hole 5a is drilled in the center of the intermediate mold 4 to pass the resin injected from the nozzle 9 through the hole 5b of the upper mold 3, and then the runner groove 5c of the lower mold 3a. ) And the ejector pins 11 are formed such that the runners are positioned in different forms so as not to interfere with the upper and lower products, and the product positions are also at different positions.

이와같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

도2에 도시된 바와같이, 노즐(9)에서 분사되는 수지가 상형틀(3)의 구멍(5b)과 중간형틀(4)의 구멍(5a)을 통과한 다음 하형틀(3a)과 중간형틀(4)에 형성된 런너홈을 따라 제품형상홈(6a)(6a')에 채워지게한 다음 상형틀(3)과 중간형틀(4)의 상면에 형성된 런너홈에 따라 제품 형상홈(6)(6')에 채워져 제품이 성형되는 것이다.As shown in Fig. 2, the resin sprayed from the nozzle 9 passes through the hole 5b of the upper mold 3 and the hole 5a of the intermediate mold 4, and then the lower mold 3a and the intermediate mold. The product-shaped grooves 6 and 6a 'are filled in the product-shaped grooves 6a and 6a' along the runner grooves formed in the product-shaped grooves. 6 ') and the product is molded.

상기와 같이 성형된 제품은 상형틀(3)이 열리면서 상형틀(3)의 상부에 돌설된 가이드봉(10)이 빠져나오면서 중간형틀(4)을 상형틀(3) 방향으로 당기게 되는데 이때 중간형틀(4)과 하형틀(3a)의 측면에 설치된 삼단봉(8)과 하형틀(3a)에 설치된 다수개의 이젝트핀(11)에 의하여 상,하단면에 성형된 제품의 런너(13)와 제품(12)이 각 형틀로부터 이탈되도록 한다.The molded product as described above is to pull the intermediate mold 4 in the direction of the upper mold (3) while the guide rod 10 protruding from the upper portion of the upper mold (3) while the upper mold (3) is opened. (4) and the runner 13 and the product of the product formed on the upper and lower surfaces by the three-stage rod (8) installed on the side of the lower mold (3a) and the plurality of eject pins (11) installed on the lower mold (3a) 12) is to be separated from each template.

이렇게 상형틀(3) 및 중간형틀(4)과 하형틀(3a)로부터 이탈된 제품은 자동커팅기(15)와 자동취출기(도면에는 표기되지 않았음)에 의하여 하단부에 있는 런너를 절단함과 동시에 상,하단면에 성형된 제품을 취출하게 된다.The product separated from the upper mold (3), the intermediate mold (4) and the lower mold (3a) by cutting the runner at the lower end by the automatic cutter 15 and the automatic ejector (not shown) At the same time, the product molded in the upper and lower cross-section is taken out.

이와같은 본 고안은 중간 형틀의 상,하부면에 캐비티 수를 가공하여 상하형틀 사이에 설치하므로서 사이즈가 적은 금형으로 짧은 시간내에 많은 수량의 제품을 사출할 수 있어 작업 능률 향상 및 원가절감의 효과를 얻을 수 있게한 것이다.The present invention is designed to process the number of cavities on the upper and lower surfaces of the intermediate mold and install it between the upper and lower molds, so that a large number of products can be injected in a short time with a small mold, thereby improving work efficiency and reducing costs. To get it.
