Abstract
A clamping apparatus includes a fixed die plate (21) fixed to a frame (26), four tie rods (23), (24) extending in the horizontal direction and respectively fixed to the fixed die plate (21) in parallel to each other, a moving die plate (22) supported to the four tie rods (23), (24) so that the moving die plate (22) can slide freely and a clamping mechanism for moving the moving die plate (22) forward and backward along the four tie rods (23), (24). This clamping apparatus comprises a guide mechanism (25) for downwardly or upwardly supporting the moving die plate (22) and which allows the moving die plate (22) to move in the opposite direction of gravitation.
