Claims

[Scope of Claim for Utility Model Registration] (1) A multi-stage system in which a plurality of molds are arranged in multiple stages between a top beam that faces each other and approaches and moves away from each other using lifting means, and a table below the top beam, and these molds are pressed simultaneously. A press, wherein a guide bar is provided between the top beam and the table and is slidable on at least one of them,
This multi-stage tunable press is characterized in that a coil spring with a constant pitch is inserted into the guide bar, and a plurality of molds are arranged around the coil spring at equal distances. (2) A multi-stage press in which a plurality of molds are arranged in multiple stages between a top beam that approaches and moves away from each other by a lifting means and a table below the top beam, and presses these molds simultaneously; The molds of each stage arranged between the top beam and the table are attached to the top beam side using separate hydraulic cylinders, or they are attached to the table side, and each hydraulic cylinder is connected to a pressure oil source so that the molds can be moved upward or downward. A multi-stage synchronized press characterized in that each of the hydraulic cylinders is configured or controlled so that the dies are moved up and down at a speed proportional to the distance traveled by each of the dies. (3) The space between the top beam, which approaches and moves away from each other by the lifting means, and the cylinder part of the hydraulic cylinder that supports the table below is separated from the outside by a partition wall to form a sealed space, and a vacuum device is installed in this space. The suction ports of the molds are connected, the molds are arranged in multiple stages in the space, and the molds of each stage are suspended by a cylinder rod of a hydraulic cylinder attached to the top beam side or supported on the table side. . A multi-stage vacuum press, characterized in that a door with a sealed structure that can be opened and closed is formed on at least one wall surface on the side periphery of the partition wall surface.
