摘要

Movable platen (12) is built by first movable platen (17) and second movable platen (18), and the second movable platen (18) is arranged so as to allow moving over a given range along the direction perpendicular to the moving direction of the first movable platen (17), so that any micro displacement of movable die (62) relative to fixed die (61) can be coped with by movement of the second movable platen (18) to thereby attain high-precision interlocking of the movable die (62) with the fixed die (61). Accordingly, accurate clamping between the fixed die and the movable die can be carried out to thereby attain production of high-precision shaped articles.
