摘要

PURPOSE:To permit clamping of molds regardless of the thickness of molds by a method in which lock parts to be provided to a tie rod ae supported on a common plate, and the plate is faced a locking cylinder and controllably regulated to given position by a lock positioning means. CONSTITUTION:A coupling portion 11 for clamping is formed on the periphery above a fixed mold 2 of each tie rod 3. In relation to the coupling portion 11, lock parts 12 are provided on the tie rod 3 in a slidable manner in the axial direction and also in a detachable manner to the coupling portion 11. Eack lock part 12 is integrally supported by fixing a casing 12a to the upside of a common lock plate 16 which is slidably fitted over each tie rod 3. A locking cylinder 17 is provided in a place corresponding to each lock part 12 between the downside of the lock plate 16 and the upside of the slide 5.
