The connection fitting (C) called compression fitting is used in the conventional method that is taken out through the cooling box (B). As shown in the enlarged view of FIG. 4, the sheath (1) is pulled out from the hole penetrating the back surface of the cooling box (B), and the pipe taper screw (2) is screwed into the hole, ) Part is sealed, and further external screw (3)
Also, by mounting the top (4) made of a metal material and tightening the outer screw (3), the deformation of the top (4) is utilized to seal the part (b).
しかるに上記コンプレッションフィッティング方式によ

された外ネジを冷却箱のシース取出側に固定し、次いで
シースの先端を鋳型本体に取付ける。However, in the case of the compression fitting method, since the hollow holes formed in the taper screw and the outer screw are only large enough for the sheath (1) to pass through, the sleeve (5) with the compensation lead wire (6) connected to the sheath (5) is used. ) Cannot be passed. Therefore, the procedure for attaching the tip of the sheath to the mold body and fixing it to the cooling box is as follows: 1) Cool the tip with the sheath connected to the sleeve inserted from the sheath tip side through the hollow hole of the taper screw and the external screw. The sheath has play (7) between the mold body and the cooling box as shown in Fig. 5 (a) because it is necessary to penetrate both side walls of the box and attach the tip of the sheath to the mold body. Wiring. Then, in this state, the taper screw is tightened to fix the taper screw and the outer screw loosely screwed to the taper screw to the sheath extraction side of the cooling box, and then attach the tip of the sheath to the mold body.
２）次に第５図（ロ）に示す様に冷却箱（Ｂ）を鋳型本

き込んだり、シースを損傷することが多い。As described above, in the conventional method, since it is necessary to provide a sheath play (7) between the mold body and the cooling box, the length of the sheath becomes excessively long. You need to be very careful when approaching.
In measuring the temperature of a mold, it is common to measure at many points in the vertical direction. Therefore, it takes time and effort to move the cooling box to the mold body in which a large number of thermocouples are arranged, and even with the utmost care, the sheath is often wound between the mold body and the cooling box and the sheath is damaged.
