摘要： A clamping apparatus includes upper and lower platens; one or more tiebars connecting the platens; and an intermediate platen between the upper and lower platens for movement relative to and along the tiebars. Upper and lower mold halves are provided on the upper and intermediate platens, respectively. A linkage connects the lower and intermediate platens. The linkage includes upper and lower links connected with each other for rotation on an intermediate shaft. The upper and lower links are pivotably supported on first and second shafts fixed to the intermediate and lower platens, repectively. The intermediate shaft is operatively connected with a drive mechanism so that the drive mechanism transmits a driving force to the linkage, and the lower platen is moved relative to the intermediate platen. A set of a radical needle bearing and a thrust bearing is used for at least one of the intermediate, first, and second shafts.
