본 고안은 사출금형장치에 있어서, 제품을 형성하는 코어를 회전시키면서 게이트를 자동적으로 절단시킬 수 있도록 한 게이트 자동절단장치에 관한 것이다.The present invention relates to a gate automatic cutting device that is capable of automatically cutting a gate while rotating a core forming a product in an injection mold apparatus.

종래의 사출금형 장치에 있어서는 제품성형후 제품과 스크랩을 분리시키기 위한 별도의 장치가 없었으며 이들의 분리작업은 제품성형후 수작업으로 게이트부를 일일이 절단시키므로서 가능하였다.In the conventional injection molding apparatus, there was no separate device for separating the product and the scrap after molding the product, and their separation was possible by manually cutting the gate part after the molding.

따라서, 제품과 스크랩의 분리작업이 매우 번거롭게 되었고 이의 작업공수가 많이들게 되었으며 생산성 저하의 증대한 요인이 되고 있는 점등의 문제점이 있었다.Therefore, the separation work of the product and the scrap is very cumbersome, and the labor of the work is increased and there is a problem of lighting that is an increase factor of the productivity decrease.

본 고안은 상기와 같은 문제점을 감안하여 제품 취출시 코어를 회동시키므로서 제품과 스크랩을 자동적으로 절단, 분리시킬 수 있도록 안출한 것으로 이를 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been made in order to automatically cut and separate the product and scrap by rotating the core when taking out the product in view of the above problems as described in detail based on the accompanying drawings.

고정측형판(1)과 가동측형판(2) 및 반침판(3), 코어(4) 및 이젝트핀(6)이 설치된 이젝트판(5)으로 구성된 것에 있어서, 코어(4)의 측면에 회전경사홈(7)을 형성시켜 코어(4)가 회동 가능하게 하고, 고정측형판(1)에는 핀(9)을 가진 작동편(8)을 설치토록 구성하여서 된 것으로 10은 제품, 11은 스크랩, 12는 게이트부이다.The fixed side plate 1, the movable side plate 2, the half needle plate 3, the core 4, and the eject plate 5 provided with the eject pin 6, which rotate on the side of the core 4 The inclined groove 7 is formed so that the core 4 can be rotated, and the fixed side plate 1 is provided with an operating piece 8 having a pin 9, where 10 is a product and 11 is a scrap. And 12 is a gate part.

이상과 같이 구성된 본 고안은 제2a도와 같이 고정측형판(1)과 가동측형판(2)이 결합된 상태에서 제품(10)을 성형한 다음, 이를 취출시키기 위하여 파팅과 더불어 이젝트핀(6)을 작동시키면 작동편(8)과 코어(4)가 상,하로 이동되면서 코어(4)가 회전되고 이의 회전에 따라 스크랩(11)과 제품(10)사이의 게이트부(12)가 절단되는 것으로, 작동편(8)과 코어(4)가 분리될때 작동편(8)의 핀(9)이 회전경사홈(7)사이에서 수직 이동함에 따라 코어(4)가 회전되는 것이다.The present invention constituted as described above, after forming the product 10 in a state in which the fixed side plate 1 and the movable side plate 2 are coupled as shown in FIG. When the operating piece 8 and the core 4 is moved up and down, the core 4 is rotated and the gate portion 12 between the scrap 11 and the product 10 is cut according to the rotation thereof. When the operating piece 8 and the core 4 are separated, the core 4 is rotated as the pin 9 of the operating piece 8 moves vertically between the rotation inclination grooves 7.

이상과 같은 본 고안은 제품성형후 이의 취출작업시 코어를 회전시킴으로서 게이트부를 자동적으로 절단시킬 수 있으며 이에 따라 제품과 스크랩을 간편하게 분리시킬 수 있어 작업공수를 절감시킬 수 있고 생산성을 증대시킬 수 있는 점등의 특징을 지닌 것이다.The present invention as described above can rotate the core in the take-out operation after forming the product to automatically cut the gate part, and thus can easily separate the product and scrap, saving labor and increasing productivity. It is characterized by.
