[0021] The upper end surface of the operating table 1 is provided with support rods 13 at the front and rear, and the support rods 13 are respectively inserted with first rotating rods 14 on the opposite surfaces. One end of the first rotating rod 14 is respectively provided with elastic limit blocks 15 on both sides, and the support rod 13 is provided with limit holes on both sides, and the elastic limit blocks 15 are engaged in the limit holes.

[0022] Furthermore, the second fixed rod 16 forms a rotating structure with the support rod 13 through the first rotating rod 14, and the first rotating rod 14 forms an elastic locking limiting structure with the support rod 13 in the limiting hole through the elastic limiting block 15, so that the mold steel is assisted to rotate by the first rotating rod 14, and the state of the mold steel is fixed by the elastic limiting block 15 locking in the limiting hole.

[0023] The other ends of the first rotating rods 14 are respectively connected to the second fixing rods 16, and the second fixing rods 16 are respectively provided with multiple groups of grooves on the upper and lower surfaces, and a spring 17 is fixedly arranged in the groove, the other end of the spring 17 is connected to a connecting block 18, and a second rotating rod 19 is inserted between the connecting blocks 18 on the same horizontal line, and elastic limit blocks 15 are respectively provided on the outer walls at both ends of the second rotating rod 19, and corresponding limit holes are provided on the connecting blocks 18, the second rotating rod 19 is connected to a limit plate 20 on the outer wall, and mold steel is placed between the limit plates 20, and a suction cup 21 is provided on the side of the limit plate 20 close to the mold steel.

At the same time, the staff can remove the second quenching head 11 on the operating head 8, so as to manually quench the smaller slits and other positions on the mold steel, and then the quenching efficiency of the device for the mold steel is increased by the synchronous operation of the two sets of quenching heads; for mold steel When the front quenching is completed, the spring 17 can be pulled upwards, and the elastic limit block 15 on the second rotating rod 19 above can be pressed at the same time, so that the limit plate 20 is rotated in the direction of the mold steel under the action of the second rotating rod 19, and then the suction cup 21 on the limit plate 20 can be adsorbed on the surface of the mold steel, so that the mold steel can be squeezed and limited by the suction cup 21, the limit plate 20 and the spring 17; when the mold steel is limited, the support plate 24 can be driven to descend by the electric push rod 22, so as to avoid the support plate 24 from hindering the rotation of the mold steel, and then the elastic limit block 15 on the first rotating rod 14 can be pressed, so that the mold steel can be assisted to rotate by the first rotating rod 14 under the action of its own gravity, so as to avoid the mold steel being too heavy to be turned over, and after the mold steel is turned over, the limit plate 20 above the mold steel is rotated outward by the same principle, so as to facilitate the quenching of the surface of the mold steel.
