Title
(EN) SIDE GATE VALVE DEVICE OF HOT RUNNER
(FR) DISPOSITIF DE ROBINET-VANNE LATÉRAL DE CANAL DE CAROTTE CHAUFFÉ
(KO) 핫런너의 사이드게이트 밸브장치
Abstract
(EN)
Disclosed is a side gate valve device of a hot runner. The side gate valve device of a hot runner of the present invention is configured such that a main resin path is formed inside a lifting runner pin and a resin bypass is formed outside the lifting runner pin, so that a resin flows inside and outside the lifting runner pin and is discharged. As such, the present invention can ensure the reliability of operation by preventing an elevating operation of a lifting runner pin from being disabled due to the phenomenon where a resin penetrates into and solidifies a gap which is formed on an outer surface of a conventional lifting runner pin due to a machining error or thermal expansion.

L'invention concerne un dispositif de robinet-vanne latéral d'un canal de carotte chauffé. Le dispositif de robinet-vanne latéral d'un canal de carotte chauffé de la présente invention est conçu de telle sorte qu'un trajet principal de résine est formé à l'intérieur d'une tige de canal de carotte d'élévation et une dérivation de résine est formée à l'extérieur de la tige de canal de carotte d'élévation, de telle sorte qu'une résine s'écoule à l'intérieur et à l'extérieur de la tige de canal de carotte d'élévation et est évacuée. Ainsi, la présente invention peut garantir la fiabilité de fonctionnement par le fait d'empêcher la désactivation d'un fonctionnement d'élévation d'une tige de canal de carotte d'élévation en raison du phénomène où une résine pénètre et se solidifie dans un interstice qui est formé sur une surface externe d'une tige de canal de carotte d'élévation classique en raison d'une erreur de machine ou d'une dilatation thermique.

본 발명은 핫런너의 사이드게이트 밸브장치를 개시한다. 본 발명의 핫런너의 사이드게이트 밸브장치는 승강 런너핀의 내부로는 메인 수지로를 형성하고 외부로는 우회수지로를 형성함에 따라 상기 승강 런너핀의 내,외부로 수지가 유동되어 배출되도록 구성되어 있으므로 종전의 승강 런너핀의 외면에 가공오차나 열팽창에 의해 형성된 간극으로 수지가 침투하여 고화되는 현상으로 인해 승강 런너핀의 승강동작이 불능 상태로 빠지는 것을 방지하여 동작의 신뢰성을 보장할 수 있도록 한 것이다..
