Abstract
The invention provides a secondary ejection device of an ejector sleeve, and belongs to the technical field of die-casting dies. The secondary ejection device solves the problems that an existing secondary ejection device of an ejector sleeve is low in ejection efficiency. The secondary ejection device of the ejector sleeve comprises a fixed die, a lower needle plate, an ejector sleeve assembly and a synchronization assembly. The lower needle plate is arranged below the fixed die and connected with the fixed die. The ejector sleeve assembly is arranged between the fixed die and the lower needle plate, the lower end of the ejector sleeve assembly is arranged on the lower needle plate in an inserted manner, and the upper end of the ejector sleeve assembly penetrates the fixed die and stretches outwards. The two ends of the synchronization assembly are connected with the fixed die and the lower needle plate correspondingly. When the synchronization assembly is in contact with the lower needle plate, the lower needle plate can drive the fixed die to move synchronously, and the synchronization assembly moves along with the lower needle plate. When the synchronization assembly is separated from the lower needle plate, the ejector sleeve assembly is static, and the lower needle plate can drive the fixed die to continue to move. The secondary ejection device of the ejector sleeve has the beneficial effects of being reasonable in layout and high in ejection efficiency.
