The present invention relates to a locking system for a tandom injection molding machine, which can open and close a parting line between a movable mold and an medium mold and a parting line of the medium mold and a fixed mold. The locking system for a tandom injection molding machine comprises a fixed mold block, a movable mold block installed at one side of the fixed mold block movably to the fixed mold block, and a medium mold block installed between the fixed mold block and the movable mold block movably to the fixed mold block. Particularly, the locking system for a tandom injection molding machine comprises: a first locking member including a first medium fixing port installed at one side of the medium mold block and a first key fixing port installed in the vicinity of the medium mold block to be in contact with the first medium mold block; a second locking member including a second medium fixing port installed at the other side of the medium mold block and a second key fixing port installed in the movable mold block in the vicinity of the medium mold block to be in contact with the second medium fixing port, and disposed apart from the first locking member to have a predetermine distance in the diagonal direction from the first locking member; a key block installed between the first locking member and the second locking member movably in the longitudinal direction and including a first key groove to which the first locking member is inserted and a second key groove to which the second locking member is inserted, wherein the first and the second key grooves are spaced apart from each other in the diagonal direction; and an actuator for moving the key blocks in the longitudinal direction. |
