Abstract
The invention relates to a mold clamping unit on a plastic injection molding machine, the unit having a clamping mechanism for opening and closing an injection mold, the mechanism having a servo motor as the drive motor (). The drive motor drives at least one spindle drive () which has a spindle nut () and spindle which work together on a bearing position (). A cooling system with cooling channels () is provided for removing heat from the clamping mechanism. A more efficient cooling of the spindle drive is achieved in that the cooling channels () penetrate the bearing position () of the spindle drive () and/or one of the cooling plates () assigned to the bearing position.
