ABSTRACT:
A hydraulic press comprising a hydraulic cylinder including a cylinder tube and a piston slidable within the cylinder tube and having a piston rod extending from the piston and adapted for actuating a movable die of a metallic mold including a stationary die cooperating with the movable die. The cylinder tube (11) of the hydraulic cylinder (10) is extended beyond the piston rod (14) and secured at its extended end to a base plate (15), and an extended portion of the cylinder tube is provided with at least one opening (16) for inserting the metal mold (9) in a space (19) within the extended portion (20) of the cylinder tube (11) to set the movable die (a) on the end of the piston rod (14) and the stationary die (9b) on the base plate (15) and thereby to reduce weight and manufacturing cost of the hydraulic press having a high strength against eccentric load and further to provide an improved hydraulic press easily changeable in its layout.
