Abstract

A double coloured plastic injection machine comprises a moving template, a rotating disc installed at one side of the moving template, at least one ejection mechanism installed at the other side of the moving template, several ejector rods connected to the at least one ejection mechanism, and several extension rods. The moving template is provided with through holes which are used for the ejector rods to pass through, the rotating disc is provided with several stepped holes which can hold the extension rods, each extension rod comprises a cylindrical body and a head part arranged on one end of the cylindrical body, the ejector rods can be driven by the at least one ejection mechanism to push the cylindrical bodies of the extension rods, and each stepped hole comprises at least one blocking wall used for preventing head parts of corresponding extension rods from moving towards the moving template. The extension rods are installed in the rotating disc of the double coloured plastic injection machine to cooperate with the ejection of the ejector rods, and therefore the ejection stroke of the ejector rods is prevented from being increased, useless running time is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a two-color injection molding machine. Background technique [0002] Compared with the traditional injection molding machine, the two-color injection molding machine adds a turntable. The turntable has a certain thickness, which causes the ejection stroke of the ejector rod to be lengthened, increases the idle running time, and reduces the production efficiency. Contents of the invention [0003] In view of the above, it is necessary to provide a two-color injection molding machine with reduced idle time. [0004] A two-color injection molding machine, comprising a movable template, a turntable installed on one side of the movable template, at least one ejector mechanism installed on the other side of the movable template, and several ejector rods connected to the at least one ejector mechanism and a number of extension rods, the movable formwork is provided with a number of perforations for these push rods to pass through,...
