Description

사출 및 압출용 믹싱노즐{Mixing nozzle for injection and extrusion}[0001] The present invention relates to mixing nozzles for injection and extrusion,

본 발명은 사출 및 압출용 믹싱노즐에 관한 것으로, 더 상세히는 믹싱조즐의 구조를 개선하여 첨가제와 용융수지의 색 농도 균일화함과 아울러 선명한 색상 표현이 가능한 사출 및 압출용 믹싱노즐에 관한 것이다.The present invention relates to a mixing nozzle for injection and extrusion, and more particularly, to a mixing nozzle for injection and extrusion which improves the structure of a mixing nozzle to uniformize the color density of the additive and the molten resin, and can display a clear color.

일반적으로, 플라스틱의 압출 또는 사출 성형 공정에서 색상을 첨가할 경우에, 특히 별도로 콤파운딩 작업을 거친 수지를 사용하지 않을 경우에는 색상의 혼합이 이루어지지 않아 색상이 한곳으로 몰리게 되는 현상이 발생한다. 따라서, 플라스틱 압출물 또는 사출물에 색상을 첨가하고자 하는 경우에는 별도로 가공비가 추가되는 콤파운딩된 수지를 사용해야 하므로 제품의 원가 상승이 초래된다.In general, when a color is added in the extrusion or injection molding process of a plastic, particularly when a resin that has undergone a compounding operation is not separately used, the color is not mixed and the color is mixed into one place. Therefore, when a color is to be added to a plastic extrudate or an injection molded article, a costly resin is required to be used, which requires additional processing costs.

상기의 문제점을 해소하기 위해 선출원된 플라스틱 사출성형용 노즐은 플라스틱 성형기의 일단과 연결되어 가열된 플라스틱 수지가 성형되도록 사출되는 노즐에 있어서, 플라스틱 성형기와 결합되며 내측에 관통된 요입공이 형성된 노즐몸통과, 일측은 상기 노즐몸통과 연결되며 타측은 가열된 플라스틱 수지가 토출되는 분사구가 형성된 캡으로 이루어진 노즐본체와; 상기 노즐몸통의 내측에 안착되어 가열된 플라스틱 수지가 혼합되도록 유로가 형성된 격자형상의 교차로와, 상기 교차로의 사이에서 일렬로 돌출된 돌출부로 이루어진 헤드로 구성된다. In order to solve the above problems, a nozzle for plastic injection molding, which is connected to one end of a plastic molding machine, is injected so as to mold a heated plastic resin. The nozzle is connected to a plastic molding machine and has a nozzle body A nozzle body having one side connected to the nozzle body and the other side formed with a cap having an injection port through which heated plastic resin is discharged; A lattice-shaped intersection in which a flow path is formed so as to be mixed with the heated plastic resin, which is seated inside the nozzle body, and a head made up of projections projected in a line between the intersections.

이러한 플라스틱 사출성형기용 노즐은 가열된 플라스틱 수지가 헤드에 형성된 교차로를 통과하면서 와류 현상이 발생되어 수지와 첨가 물질의 혼합이 이루어질 수 있다. 그리고 노즐은 교차로가 헤드의 외주면에 형성되어 수지와 첨가 물질이 헤드의 외주면을 따라 나선 형상으로 이동하면서 교차되기 때문에 수지와 첨가 물질이 어느 정도 혼합 가능하지만 균일하게 혼합되는 것은 불가능하였다.Such a nozzle for a plastic injection molding machine can generate a vortex phenomenon while passing a heated plastic resin through an intersection formed on a head, so that the resin and the additive material can be mixed. In addition, since the nozzle and the nozzle are formed on the outer circumferential surface of the head, the resin and the additive material are mixed with each other while moving in a spiral shape along the outer peripheral surface of the head.
