본 고안은 사출금형에서 성형되는 제품의 길이가 1060㎜폭이 65㎜정도되는 긴 띠 형상의 제품을 성형할때 제품의 변형을 방지하는 장치에 관한 것으로서, 특히 금형의 성형코어부 중심에 즉 용융수지 주입부 위치에 Be-Cu재질의 코어를 설치하여 이 내부로 제품이 성형되는 동안 냉각수를 직통으로 주입 순환시켜 주어 게이트부의 온도를 내리고, 밀도를 높이며, 수축량을 줄여 제품의 변형을 방지하여 줄 수 있도록 한 사출 금형의 제품 변형장치에 관한 것이다.The present invention relates to a device for preventing deformation of a product when molding a long strip-shaped product having a length of about 1060 mm and a width of about 65 mm, which is molded in an injection mold. The core of Be-Cu material is installed at the location of the resin injection part to inject and circulate the cooling water directly while the product is molded into the inside to lower the temperature of the gate part, increase the density, and reduce the shrinkage to prevent deformation of the product. The present invention relates to a product deformation apparatus of an injection mold.

일반적으로 상기와 같이 긴 띠 형상의 제품을 사출금형에서 성형하게 되면 성형부 게이트부를 안고 제품이 안쪽으로 취는 현상이 발생 하였던 것이다.In general, when the long strip-shaped product is molded in the injection mold as described above, the phenomenon in which the product is taken inwards while holding the gate part of the molding part occurs.

따라서 상기와 같은 현상을 방지하고져 종래에도 여러가지 방법으로 변형방지를 하였으나 큰 실요를 거두지 못하였고 또한 상기의 종래 방법들은 모두 그 구조가 복잡하여 금형제작에 어려움이 많았던 것이다.Therefore, the above-described phenomenon was prevented, but the deformation prevention was prevented by various methods in the related art, but it was not a big requirement. In addition, all of the above-described conventional methods had a complicated structure, which made it difficult to manufacture a mold.

본 고안은 상기와 같은 종래의 문제점들을 보완하고져 사출금형의 성형코어 게이트부에 Be-Cu재질의 코어를 설치하고, 이에 배관라인을 연결하여 제품 성형시 이내부로 냉각수를 직통으로 순환시켜 제품의 변형을 방지하여 줄 수 있게 한 것으로서 이하 본 고안을 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention complements the above-mentioned problems and installs a Be-Cu core at the molded core gate portion of the injection mold, and connects a pipe line to circulate the coolant directly to the inside of the product to deform the product. The present invention will be described in detail below with reference to the accompanying drawings.

본 고안의 구성을 보면 제1도와 제2도에서 보는 바와 같이 통상적으로 고정측 설치판(2)과 고정측 형판(3), 고정측 코어(4)및 가동측 코어(5)와 가동측 형판(6), 가동측 설치판(7)으로 구성되는 사출금형(1)에 있어서, 상기 사출금형(1)의 가동측 코어(5)와 고정측 코어(4)의 내부로 게이트 위치에 Be-Cu재질의 코어(8)(8′)를 설치하고, 이에 냉각수공급용 배관(9)(9′)을 각각 연결 설치하여 구성된 것이다.In the construction of the present invention, as shown in FIG. 1 and FIG. 2, the fixed side mounting plate 2 and the fixed side template 3, the fixed side core 4, and the movable side core 5 and the movable side template (6) In the injection mold (1) consisting of the movable side mounting plate (7), Be- at the gate position inside the movable side core (5) and the fixed side core (4) of the injection mold (1). The core 8 (8 ') of Cu material is provided, and the cooling water supply piping 9 (9') is connected and installed, respectively.

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

먼저 금형(1)을 폐형 시킨 후 용융수지를 주입하여 가동축 코어(5)와 고정측 코어(4)사이에서 제품(P)을 성형하는 동안 냉각수 공급용 배관(9)(9′)을 통하여 냉각수를 공급하게 되면 내부 Be-Cu코어(8)(8′)에 냉각수가 공급되어 제품(p)성형부의 게이트부를 냉각시켜주어 게이트부의 밀도를 높이고, 수축량을 줄여 제품(P)의 변형을 방지할 수 있게 되는 것이다.First, the mold 1 is closed, and then molten resin is injected to form the product P between the movable shaft core 5 and the fixed core 4 through the cooling water supply pipe 9 and 9 '. When the coolant is supplied, the coolant is supplied to the internal Be-Cu core 8 (8 ') to cool the gate part of the product (p) molding part, thereby increasing the density of the gate part and reducing the shrinkage to prevent deformation of the product (P). You can do it.

그러므로 간단한 구조로 제품의 변형을 방지하게 되므로 금형의 구조가 간단하여 제작비를 줄일 수 있고 또한 게이트부에 직접 냉각수를 공급하게 되므로 냉각효과를 극대화시켜 제품의 변형 방지효과를 극대화 할 수 있어 제품의 품질을 향상시키고, 불량 발생률을 극소화 시킬 수 있게 된 것이다.Therefore, since the structure of the mold is prevented by the simple structure, the structure of the mold is simple to reduce the production cost and the cooling water is directly supplied to the gate part, so the cooling effect can be maximized to maximize the effect of preventing deformation of the product. It is possible to minimize the occurrence rate of defects.
