Patent number: 7500508Abstract: An injection-molding device is for manufacturing V-engine blocks, in particular an injection-molding machine with a fixed and moving mold half, wherein the moving mold frame contains sliders and ejectors, along with center sleeve sliders angularly arranged relative to each other and a supporting plate for locking the center sleeve slider. Therefore, the force is introduced perpendicular via the center sleeve sliders, and absorbed via the supporting plate or moving identification plate. The moving mold half is secured on a mounting frame.Type: GrantFiled: January 12, 2006Date of Patent: March 10, 2009Assignee: Buhler Druckguss AGInventors: Siegfried Heinrich, Sascha Padovan, Ulrich Binder, Benno Niedermann
