ABSTRACT:
This clamping device (5) is of the type comprising a peg (6) which projects from the half-mold (2) and which is received in a recess (17) in the platen, and a clamping mechanism (5) including a transverse cylinder (9) and a wedge (8) deigned to interact with the peg in order to ensure the removable clamping of the half-mold. The clamping mechanism (5) comprises a bearing block (7) designed to be fixed at the entrance of the recess (17) and including, on the one hand, a passage (25) for the peg (6), and, on the other hand, an incline (24) for the bearing of the wedge (8), this incline being provided on that face of the block which points towards the recess in the platen. The peg (6) is axisymmetric with a widened head (14). The clamping device finds applicability in the injection-molding of plastics.
