同心位置に確実に保持することとなる。Next, in the dummy block (14), a receiving hole (16) to be engaged with the pressurizing plate is recessed in the front end surface of a substantially short columnar body with the front end protruding slightly to a large diameter. ) Has a substantially annular seal portion (15) formed on the rear end surface thereof, and a female thread hole (17) into which the male thread portion (5) of the communication rod (4) is screwed in the rear end surface in the axial direction, Next, a stepped through hole (18) having a diameter smaller than that of the female screw hole (17) and opening into the receiving hole (16) is formed, and the pressure plate (19) has a large-diameter truncated end. Conical body with female screw hole (20) at the center
The pressure plate (19) is engaged in the receiving hole (16) of the dummy block (14), and the headed connecting bolt (2) is inserted into the stepped through hole (18) from the rear side.
1) is screwed into the female screw hole (20) of the pressure plate (19) and the tip of the bolt (21) is advanced to a position almost flush with the front face of the pressure plate (19), and in that state the bolt (21) The tip is welded to the pressure plate (19). (22) indicates a welded portion. The welded portion (22) prevents the connecting bolt (21) from loosening, and thereby reliably holds the pressure plate (19) in a concentric position with the dummy block (14).

The rear end of the tapered surface is a partial taper surface, in this example, the rear half surface (rear end is a taper half surface) is recessed rearward from the bottom surface (23) of the receiving hole (16), and the front end is tapered. Forming an annular escape chamber (24) continuous with the half surface and concentric with the outer peripheral surface of the dummy block (14),
The seal portion (15) is made long in the axial direction by the vacant chamber (24) to further facilitate the expansion. In this example, the angle of inclination of the truncated cone of the pressure plate (19) is made slightly larger than that of the truncated cone of the receiving hole (16),
This ensures that the seal portion (15) of the pressure plate (19) is expanded.

る。When not in use, the pressure board (19) slightly projects from the tip surface of the dummy block (14) as shown in the second illustration, and its rear end surface is slightly spaced from the bottom surface (23) of the receiving hole (16). When the pressurizing plate (19) is exposed to high pressure on the front surface, the rear end face is the bottom of the receiving hole (23).
The seal portion (15) is expanded rearward until it comes into contact with the seal member (15) to a predetermined diameter. At that time, the tip surface of the pressure plate (19) is flush with the tip surface of the dummy block (14).

The block is connected to the crocodile, and then the connecting rod (4) is opened into the connecting rod insertion hole (2) of the stem (1) whose rear end is supported by the extruder body (E). The stem is fitted with the locking hole (26) in the whirl-stop pin (25), and then the cotter (7) is inserted into the cotter holes (3) of the stem (1) and the connecting rod (4). ), (6), and when fully inserted, the locking hole (8) comes out and the retaining pin (11)
Automatically locks and prevents the cotter (7) from coming off.

を有効に維持する。After connecting the dummy block (14) to the stem (1) as described above, the dummy block (14) is pushed into the container and the billet is extruded. In the above-mentioned extrusion, the pressure plate (19) receives a high pressure, and the tip of the receiving hole (16) presses the half surface of the taper toward the outer peripheral direction by the frustoconical taper surface of the sealing plate (15) by elastic displacement. It is expanded and the seal portion (15) is brought into pressure contact with the inner peripheral surface of the container for sealing. In this case, the relief chamber (24) facilitates the expansion of the seal portion (15) and wear generated from the contact portions of both the pressure platen (19) and the tapered surface of the receiving hole (16) at the time of extrusion. Foreign matter such as powder is immediately received and held in the escape empty chamber (24), and further, since the empty chamber (24) extends rearward from the bottom surface (23) of the receiving hole (16),
The received foreign matter is transferred to the rear surface of the pressure plate (19) and the bottom surface of the receiving hole (2
It is held with almost no intervention between it and 3), thereby effectively maintaining the expanding action on the seal portion (15) of the pressure plate (19).

The cotter (7) is pulled out while it is supported, and then the connecting rod (4) is pulled forward from the stem (1) to separate the dummy block (14) from the stem (1). Next, the broken connecting rod (4) is removed from the dummy block (14), and the male screw portion (5) of the new connecting rod (4) is screwed into the female screw hole (17) of the dummy block. Similarly, connect the dummy block (14) to the stem (1).
