【考案の詳細な説明】
本考案は、金属の間接押出プレスの改良に関す
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in metal indirect extrusion presses.
従来の間接押出プレスにおいては、ダイスとダ

去に時間がかかりメンテナンス上でも問題があつ
た。 In conventional indirect extrusion presses, molten metal flows into the gap between the die and the die holder, which causes them to stick together, making it difficult to remove the die when replacing the die. In addition, it took a long time to remove metal scum adhering to the inner surface of the die holder, which caused problems in terms of maintenance.

る。なお、第１図中１３はビレツトである。 The present invention aims to solve this problem, and the embodiment will be explained based on the drawings. Fig. 1 is an enlarged sectional view of the main part. An open die holding hole 3 is provided, and a die 4 consisting of a combination of a bolster 5, a bucker 6, a die 7, a buffle 8, and a sleeve 9 is inserted and held in the die holding hole 3. Further, the tip of a canister 10 that slides inside the die stem 1 back and forth in the extrusion direction so as to push out the die 4 from the die holding hole 3 is placed so that the rear surface of the die 4 inserted into the die holding hole 3 is opposed to the tip of the canister 10. In addition, a groove 11 is provided on the outer periphery of the tip of the die 4, and a seal ring 12 is attached to the groove 11 so as to elastically come into close contact with the inner circumferential surface of the die holding hole 3. As shown in FIG. 1, the outer peripheral surface of the seal ring 12 is formed into a tapered surface in which the diameter on the front end side of the die 4 is increased and the diameter on the rear end side is slightly smaller. In addition, 13 in FIG. 1 is a billet.

後面を押し、ダイス４を抜き取る。 An indirect extrusion press with such a structure is used as follows. First, in FIG. 2, the die 4 is inserted into the die holding hole 3 at the tip of the die stem 1 held by the die slide 14. and,
When a predetermined extrusion operation is started, molten metal enters between the die holding hole 3 and the die 4 due to the extrusion pressure, but the seal ring 12 is in close contact with the inner surface of the die holding hole 3. This prevents their intrusion. When the extrusion operation is completed and it becomes necessary to replace the die 4, the die slide 14 is moved to the die removal cylinder 15 as shown in FIG. Then, as shown in FIG. 4, the die extracting cylinder 15 is operated to slide the canister 10, and the canister 10 is pushed against the rear surface of the die with its tip to extract the die 4.

外周エツジにより外部に押出される。 At this time, as shown in the main part in FIG. Since it is in close contact with the circumferential surface, as the seal ring 12 moves, it is pushed out by the outer circumferential edge of the tip.

上する。 The present invention is as described above, and by providing a seal ring on the die, molten metal is prevented from flowing into the gap between the die and the die holding hole, and the die can be easily removed. In addition, when the die is removed, the outer edge of the seal ring can clean out metal debris that has flowed into the inner surface of the die holding hole, eliminating the need to specially clean the inner surface of the die holding hole. It can shorten the time for replacement work and improve productivity.
