Description

사출금형의 게이트 절단장치Gate cutting device of injection mold

제1도는 본 고안의 설치상태 단면도.1 is a cross-sectional view of the installation state of the present invention.

제2도는 본 고안의 작동상태 단면도.2 is a cross-sectional view of the operating state of the present invention.

* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

1 : 가동측취부판 2, 3 : 이젝트판1: movable mounting plate 2, 3: eject plate

4 : 이젝트핀 5 : 지지대4: eject pin 5: support

6 : 스프링 7 : 절단핀6: spring 7: cutting pin

8 : 이젝트봉8: eject rod

본 고안은 사출금형에 있어서, 제품을 취출하기전에 제품과 스크랩 사이의 게이트를 자동적으로 절단시킬 수 있도록한 게이트 절단장치에 관한 것이다.The present invention relates to a gate cutting device in an injection mold, which enables to automatically cut the gate between the product and the scrap before taking out the product.

종래에도 게이트를 절단하는 장치가 일부 안출된바 있었으나, 이는 대부분이 슬라이드코어의 동작에 따라 게이트가 절단되도록 되어 있었기 때문에 슬라이드코어의 동작을 규제하여야 하는 문제점이 있었고 또 슬라이드코어를 설치하지 않는 금형장치에 있어서는 제품과 스크랩 사이의 게이트를 자동적으로 절단시키지 못하고 수작업으로 절단하여야 하는 점등의 문제점이 있었다.In the past, a device for cutting a gate has been partially devised. However, since the gate is cut according to the operation of the slide core, most of them have a problem of regulating the operation of the slide core. In the case of the gate between the product and scrap does not automatically cut, there was a problem of the lighting that must be cut by hand.

본 고안은 상기와 같은 종래의 문제점을 감안하여 안출한 것으로 이를 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been devised in view of the above-described conventional problems, and will be described in detail with reference to the accompanying drawings.

가동측 취부판(1)의 상부에 이젝트핀(4)을 가진 상, 하 이젝트판(2)(3)을 설치하고 이의 하방에는 가동측 취부판(1)에 지지되는 지지대(5)를 설치하여 이젝트판(2)과의 사이에 스프링(6)을 탄력 설치하며 지지대(5)의 중앙에 절단핀(7)을 설치하고 이의 하방에 이젝트봉(8)을 설치토록 구성하여서된 것으로 9는 제품, 10은 스크랩, 11은 게이트이다.The upper and lower ejection plates 2 and 3 having the eject pins 4 are installed on the upper side of the movable side mounting plate 1, and below the support plates 5 supported by the movable side mounting plate 1. The spring 6 is elastically installed between the eject plate 2 and the cutting pin 7 is installed at the center of the support 5, and the ejection rod 8 is installed below it. Product, 10 is scrap, 11 is gate.

이상과 같이 구성된 본 고안은 제1도와 같이 이젝트판(2)(3)과 이젝트봉(8)이 하강된 상태에서 제품을 성형하게 되며 제품성형후 이를 취출하기 위하여 이젝트봉(8)을 상승시킨다.The present invention configured as described above forms the product in a state where the eject plate 2, 3 and the eject rod 8 are lowered as shown in FIG. 1, and raises the eject rod 8 to take it out after forming the product. .

이젝트봉(8)이 제2도와 같이 상승되면 가동측 취부판(1)에 지지된 지지대(5)가 스프링(6)을 누르면서 상승하여 절단핀(7)을 밀어주며 이때 이젝트판(2)(3)은 정지되어 있다.When the ejector rod 8 is raised as shown in FIG. 2, the support 5 supported on the movable side mounting plate 1 is raised while pressing the spring 6 to push the cutting pin 7 to the ejector plate 2 ( 3) is stationary.

상기와 같이 절단핀(7)이 상승되면 제품(9)과 스크랩(10) 사이에 게이트(11)를 밀어 절단시키게 되며 게이트(11) 절단후 이젝트봉(8)에 의하여 지지대(5)와 이젝트판(2)(3)이 함께 상승되고 이젝트핀(4)이 제품(9)과 스크랩(10)을 취출하게 되는 것이다.As described above, when the cutting pin 7 is raised, the gate 11 is pushed and cut between the product 9 and the scrap 10. After the cutting of the gate 11, the support bar 5 and the ejection rod 8 are ejected. The plates 2 and 3 are raised together and the eject pins 4 take out the product 9 and the scrap 10.

이상과 같은 본 고안은 간단한 구조로서 제품과 스크랩 취출전에 게이트를 확실하게 절단할 수 있으며 절단작업이 간편하고 용이하게 되는 점등의 특징을 지닌 것이다.The present invention as described above is a simple structure that can be reliably cut the gate before taking out the product and scrap and has the feature of lighting that the cutting operation is simple and easy.
