In technique scheme, described second return guide rod hole one end is circumferentially provided with and the compressed grooves compressing boss and match, and described second plunger tip rod aperture one end is circumferentially provided with the return groove matched with return boss.
In technique scheme, the length of described return guide rod is greater than the length of plunger tip bar.
In technique scheme, described pressing plate two ends are respectively equipped with installation screw.
What the present invention utilized Compress Spring automatically replies power, plunger tip plate is driven to move to the direction of core, return groove on plunger tip plate coordinates with return boss, plunger tip bar is driven to move, the core box of core from core making machine is ejected, accelerate the speed that core ejects, easy to use, avoid, outside the core box of core making machine, core ejecting device is set separately, save die space, reduce production cost, and the automation adopting this core ejecting device can realize core to eject from core box, without the need to manual operation, save manpower, enhance productivity, particularly more convenient for plunger tip the larger core of volume, the requirement of modern production can be met.
