Abstract: The mold clamping unit comprises a column mounted in a transfer means and moving in forward and backward direction; a mold clamping piston in which clamping operation and clamping-releasing operation are performed; plurality of column teeth disposed on a surface of the column along an axial direction of the column; center bore provided in a central of the mold clamping piston; clamping tooth seating groove with a plurality of clamping teeth inside the mold clamping piston contacting the center bore; rotating plate with plurality of clamping tooth guide grooves separated from the clamping teeth in the axial direction of the column; and a teeth rod positioned in each of the clamping tooth guide groove, wherein each teeth rod is connected to each clamping teeth during the rotation of the rotating plate, for moving each clamping tooth in a central or radial direction of the rotating plate and clamping of the clamping tooth and the column can proceed.

Abstract: A mold clamping unit is provided.

Abstract: Disclosed is a clamping apparatus for an injection molding machine, which includes a frame; a first fixed die plate fixed to the frame and on which a first half mold is mounted; a tie bar fixed to a second fixed die plate to guide a moving die plate; the moving die plate slidably installed to the tie bar and on which a second half mold corresponding to the first half mold is mounted; a coupling means installed to a rear side of the moving die plate and coupling the moving die plate and the tie bar; the second fixed die plate installed to the tie bar at the front of the first fixed die plate; and at least one piston ram installed between the fixed die plates and selectively controlling a distance between the fixed die plates so that the half molds are closely adhered or separated.
