PURPOSE:To obtain the sufficient mold clamping pressure and also to prevent moldings from being dirtied due to oil without deteriorating durability. CONSTITUTION:A table 4 is freely supported to the upper part of a base 1 via the rods 3 with permitted vertical movement. The table 4 is elevated and driven via a ball screw 21, and a nut 25 by a motor 20. A rotary disk 31 is freely rotatably provided on the base 1. A first supports 41 are downward projected on the table 4. A second supports 42 are upward projected on the rotary disk 31. Both the first supports 41 and the second supports 42 are alternately made parallel in the horizontal direction at a mold opening time and aligned in the vertical direction and mutually collide at a closing time. The supporting member 5 of a bottom force is elevated and driven for the table 4 by a hydraulic cylinder device 51. Thereby amount of oil in the device 51 is reduced. Sufficient mold clamping force is generated by the device 51. The ball screw 21, resists the mold clamping pressure by the help of the supports 41, 42. |
