Definitions

  • the injection unit E is an electromechanical spindle drive with a spindle 18 which is driven by the drive motor 51, the drive motor in the carrier block 10 is stored.
  • the force of the drive motor can be transmitted via a reduction gear designed as a planetary gear set 51a to a region 18a of reduced diameter, which is mounted on bearings 23 on a molded part 10a of the carrier block 10.
  • a nut 11 is fixed in a rotationally fixed manner on the injection bridge via fastening means 11a.
  • a reversal of the arrangement of spindles and nuts or an arrangement of the injection motor 51 on the injection bridge is possible in principle, but would have the disadvantage that larger masses have to be moved.

Abstract

L'unité de moulage par injection proposée comporte plusieurs unités d'entraînement électromécaniques (A) disposées symétriquement par rapport à l'axe d'injection et servant à pousser l'unité de moulage par injection jusqu'à ce que la buse repose contre le moule, ainsi que plusieurs unités d'injection électromécaniques (E) disposées symétriquement par rapport à l'axe d'injection et servant à déplacer le pont d'injection (25) par rapport au bloc de support (10). A cet effet, le pont d'injection et le bloc de support peuvent être déplacés le long d'éléments de guidage (83) linéaires. Ces éléments de guidage (83) sont disposés symétriquement par rapport à l'axe d'injection, tandis que les unités d'entraînement (A), les unités d'injection (E) et les éléments de guidage (83) se trouvent dans des plans différents (h-h, e-e, f-f) qui comprennent l'axe d'injection (s-s).
