[0038] Example 3

[0039] like Figure 4 As shown, the self-locking mechanism 39 includes a self-locking frame 391 arranged inside the mold body 1, a guide rod 392 is fixedly connected inside the mold body 1, a push rod 393 is fixedly connected to one side of the self-locking frame 391, a spring 394 is sleeved on the outer surface of the push rod 393, a push plate 395 is fixedly connected to one end of the push rod 393, and a push block 396 is fixedly connected to one side of the push plate 395. An active groove adapted to the self-locking frame 391 is provided inside the mold body 1, and a self-locking groove adapted to the self-locking frame 391 is provided on the outer surface of the fixed rod 32. By providing the self-locking groove, the fixed rod 32 can be fixed inside the mold body 1 with the help of the self-locking frame 391, and one end of the push rod 393 slides through one side of the inner wall of the active groove, and the mold body 1 A push groove compatible with the push plate 395 is provided inside, one end of the spring 394 is welded to one side of the inner wall of the push groove, and the other end of the spring 394 is welded to one side of the push plate 395, and a guide hole compatible with the guide rod 392 is provided on one side of the push plate 395. By providing a movable groove, the self-locking frame 391 can move normally inside the mold body 1, and by providing a push groove, the push plate 395 can move normally inside the mold body 1.

The spring 394 is affected by the force of the push plate 395 moving, and its shape gradually changes. As the side plate 31 is pushed until it can no longer move, the fixed rod 32 stops moving inside the mold body 1 and the self-locking frame 391. At this time, the self-locking frame 391 corresponds to the self-locking groove on the fixed rod 32, and the self-locking frame 391 is no longer affected by the force of the movement of the fixed rod 32 and stops. At the same time, the push plate 395 stops moving, and the spring 394 is no longer affected by the force and gradually restores its shape, and actively drives the push plate 395 to move. During the movement of the push plate 395, the push rod 393 is used to drive the self-locking frame 391 to move. As the self-locking frame 391 moves, it gradually engages with the self-locking groove on the fixed rod 32 until the self-locking frame 391 and the fixed rod 32 are self-locked.

[0041] Working principle:

[0042] like Figure 1-6As shown, during installation, the cooling pipe 2 with the fixed sleeve 334 and the positioning sleeve 333 is fixed on the base 310 and positioned with the side frame 331. The fixing block 335 is inserted into the inside of the base 310, and the fixing sleeve 334 gradually approaches the base 310 as the fixing block 335 is inserted, until the fixing sleeve 334 is completely in contact with the base 310, and the fixing block 335 is completely inserted into the inside of the base 310. Keep the cooling pipe 2 in the position where the fixing sleeve 334 is in contact with the base 310, slowly push the side frame 331 to move, the side frame 331 gradually approaches the base 310, and drives the connecting rod 337 to move, the connecting rod 337 gradually moves toward the inside of the base 310, and drives the limit plate 338 to move inside the base 310. As the side frame 331 moves, the clamping rod 336 is gradually inserted into the inside of the base 310, and gradually penetrates the base 310 and is inserted into the inside of the fixing block 335. During the movement of the side frame 331, the side frame 331 gradually approaches the positioning sleeve 333 sleeved on the outer surface of the cooling tube 2, and pushes the side frame 331 until it is completely in contact with the base 310, the positioning sleeve 333 is completely inserted into the inside of the side frame 331, and the clamping rod 336 is inserted into the inside of the fixing block 335. The cooling tube 2 is positioned and fixed on the base 310 using the positioning sleeve 333 and the fixing sleeve 334. The side plate 31 is fixed to one side of the mold body 1, the fixing rod 32 and the rotating rod 37 are inserted into the inside of the mold body 1, and the side plate 31 is slowly pushed to move, the side plate 31 gradually approaches the mold body 1, and as the side plate 31 moves, the rotating rod 37 gradually inserts into the inside of the mold body 1 following the movement of the side plate 31, and drives the threaded rod 38 to gradually approach the thread groove inside the mold body 1, until the side plate 31 is pushed until the threaded rod 38 contacts the thread groove. Use a tool to rotate the screw block 35, and before rotating the screw block 35, ensure that the screw sleeve 34 remains fixed. The threaded rod 38 gradually rotates as the screw block 35 rotates, and gradually inserts into the inside of the thread groove, and the side plate 31 continues to approach the mold body 1 until the screw block 35 is rotated until it can no longer rotate, and the side plate 31 overlaps with the mold body 1. As the fixed rod 32 is inserted into the inside of the mold body 1 and slowly pushes the movement of the side plate 31, the fixed rod 32 contacts the self-locking frame 391 inside the mold body 1. The self-locking frame 391 is affected by the force of the movement of the fixed rod 32, and actively moves inside the mold body 1, and drives the push rod 393 to move. During the movement of the push rod 393, the push plate 395 is driven to move. The push plate 395 slides on the outer surface of the guide rod 392 and drives the push block 396 to move. The spring 394 is affected by the force of the movement of the push plate 395 and its shape gradually changes.As the side plate 31 is pushed until it can no longer move, the fixed rod 32 stops moving inside the mold body 1 and the self-locking frame 391. At this time, the self-locking frame 391 corresponds to the self-locking groove on the fixed rod 32, and the self-locking frame 391 is no longer affected by the force of the movement of the fixed rod 32 and stops. At the same time, the push plate 395 stops moving, and the spring 394 is no longer affected by the force and gradually restores its shape, and actively drives the push plate 395 to move. During the movement of the push plate 395, the push rod 393 is used to drive the self-locking frame 391 to move. As the self-locking frame 391 moves, it gradually engages with the self-locking groove on the fixed rod 32 until the self-locking frame 391 and the fixed rod 32 complete self-locking.

[0043] When in use, the cooling pipe 2 passing through one side of the mold body 1 is connected to the cooling equipment, one end of the cooling pipe 2 is the coolant inlet, and the other end is the coolant outlet. After the cooling pipe 2 is connected to the cooling equipment, as the mold body 1 is used in the production process of mechanical parts, when the processed parts inside the mold body 1 need to be cooled, the cooling equipment is started to add coolant to the inside of the cooling pipe 2. After the coolant enters the inside of the cooling pipe 2, the cooling pipe 2 gradually cools the mold body 1, so that the mechanical parts processed inside the mold body 1 complete the cooling treatment inside the mold body 1.
