Abstract
The present invention relates to a guiding and centering device () for a forming tool (), in particular an injection molding or die-casting tool, comprising a first mold half () and a second mold half () which are guided by guide means () from a closed position in which the respective separating surfaces of both mold halves () are pressed against one another into an opened position and vice versa. This guiding and centering device () comprises a protruding guiding body () formed as a circular cylindrical bolt () provided at the first mold half (), a guiding recess () formed as a bush () with an circular cylindrical inner surface () provided at the second mold half () and a rolling element cage () with rolling elements () inserted in rows (), by means of which the two mold halves () are guided and precisely centered in the closed position. The rolling element cage () is supported by the circular cylindrical inner surface () of the bush () and positioned via positioning means () in such a way that when closing the forming tool the circular cylindrical bolt () runs practically simultaneously in a first row of rolling elements () and a second row of rolling elements () of the rolling element cage ().
