摘要:
Locking mechanism for extrusion head consisting of two moving units (3,8) with wedge mechanism (5, 10) for each side of extrusion head which are placed on wall (1) on carrier portion of extrusion head (2), wherein the one side moving unit (3) moves the pushing bar (4) with wedge slant (5) to the locking hole (6) in openable portion of extrusion head (7) to fix its working position. Thereafter, the second moving unit (8) moves the pushing bar (9) towards the second wedge slant (10) of pushing bar (4) in working position and by the distribution of forces on wedge slant (5) generates the closing force for resisting the pressure of plasticised material.
