Description

사출물 취출장치{Ejection device}Injection ejection device {Ejection device}

개시되는 내용은 사출물 취출장치에 관한 것으로, 더욱 상세하게는 사출성형기에서 성형을 마친 성형물을 손상없이 안정적으로 취출할 수 있도록 한 사출성형장치의 사출물 취출장치에 관한 것이다. The disclosed subject matter relates to an injection molding apparatus, and more particularly, to an injection molding apparatus capable of stably taking out a molded product molded by an injection molding machine without damage.

본 명세서에서 달리 표시되지 않는 한, 이 섹션에 설명되는 내용들은 이 출원의 청구항들에 대한 종래 기술이 아니며, 이 섹션에 포함된다고 하여 종래 기술이라고 인정되는 것은 아니다.Unless otherwise indicated herein, the material described in this section is not prior art to the claims of this application, and inclusion in this section is not an admission that it is prior art.

사출성형기의 작동은 두 부분으로 나누어진 금형을 장착한 형반이 두 개가 있으며, 한쪽은 고정이며 다른 한 부분이 열리고 닫힌다. The operation of the injection molding machine is that there are two platens with molds divided into two parts, one is fixed and the other part opens and closes.

즉 금형을 닫고 여는 것을 형개폐라 한다. In other words, closing and opening the mold is called mold opening and closing.

닫겨진 금형 내로 용융된 플라스틱 원재료를 사출기 실린더와 스크류를 통하여 투입하는 것을 사출이라하며, 사출성형기 실린더 내에서 스크류가 회전하면서 플라스틱 원재료를 전단력인 마찰과 열로 녹이면서 다음 사출을 위한 원하는 양의 녹은 원재료를 준비하는 것을 계량이라 한다.Injection is to inject the molten plastic raw material into the closed mold through the injection molding machine cylinder and screw, and while the screw rotates in the injection molding machine cylinder, the plastic raw material is melted with friction and heat, which are shear forces, and the desired amount of molten raw material for the next injection. Preparing for is called weighing.

사출된 원재료는 금형 내로 투입되어서 일정의 모양을 가지는 사출제품이 성형되며, 소정의 냉각 시간을 소모한 후에 형개되고 이후에 금형 내에 있는 제품을 떼어내는 작업을 에젝팅이라 한다. The injected raw material is put into the mold to form an injection product having a certain shape, and after consuming a predetermined cooling time, the mold is opened, and the operation of removing the product in the mold is called ejecting.

즉, 사출성형기의 일반적 동작 순서는 형폐, 사출, 계량, 형개, 에젝팅의 순서로 반복하면서 양산 제품을 생산한다.That is, the general operation sequence of the injection molding machine is repeated in the order of mold closing, injection, metering, mold opening, and ejecting to produce mass-produced products.
