  • Patent number: 7500508
    Abstract: 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.

  • Patent number: 6997231
    Abstract: The invention relates to a method for vacuum diecasting and a diecasting mould (1), especially for diecasting components made of metal or the alloys thereof. The aim of the invention is to provide a better casting quality while simplifying the procedure of the method. To this end, the evacuation of the die cavity (5) and the filling with molten bath are carried out independently from one another.
