In addition, when the locking pin 61 is not inserted into the locking hole 53, its upper end face is in contact with the lower end face of the limiting pressure plate 54, and the connecting spring 631 is in a stretched state at this time.

[0043] When the movable locking pin 7 cooperates with the mold body 3 to lock the mold body 3, the movable locking pin 7 is inserted into the locking socket 32 ​​on the mold body 3.

[0044] like Figure 1 , Figure 11 and Figure 12As shown, the second convenient locking component includes: a movable support block 8 and a frame 9. The movable support block 8 has an installation hole 81, and a support rod 132 is inserted into the installation hole 81. The movable support block 8 is movably installed on the installation support column 13 through the cooperation between the installation hole 81 and the support rod 132.

[0045] The lower end of the movable support block 8 is symmetrically welded with connecting rods 82. A side support plate 83 is welded to one side of the movable support block 8. An L-shaped support plate 84 is welded to the lower end of the side support plate 83. A mating connecting strip 85 is also welded to the side support plate 83.

The connecting rod 87 realizes the movable connection between the frame 9 and the movable support block 8. Thus, when the movable support block 8 moves, the frame 9 can be moved by the movable support block 8.

[0047] The connecting rod 82 at the lower end of the movable support block 8 is inserted into the connecting through hole 41 on the drive connecting plate 4. The movable support block 8 and the drive connecting plate 4 are connected by the cooperation of the connecting rod 82 and the connecting through hole 41. When the drive connecting plate 4 moves, the movable support block 8 can be moved by the drive connecting plate 4, and the connecting rod 82 can move up and down along the connecting through hole 41.

[0048] A support plate frame 91 is welded and fixed to the frame frame 9 by welding process. A support limiting post 92 is welded and fixed to the support plate frame 91 by welding process. When the support limiting post 92 is inserted into the limiting guide hole 22, it fixes the punch head 2. At this time, the support plate frame 91 is in contact with the lower end face of the mounting base 21. The support plate frame 91 can further support the punch head 2, fully ensuring its installation firmness and stability.

[0049] A process for forming sliding block bricks from special steel smelting includes the following steps: Step 1: Positioning of the stamping head 2: Position the stamping head 2 on the mounting support column 13; Step 2: Positioning of mold body 3: Position mold body 3 on mold base 15; Step 3: Locking the stamping head 2 and the mold body 3: Move the drive connecting plate 4 to fix the stamping head 2 on the mounting support column 13 and at the same time fix the mold body 3 on the mold base 15; Step 4: Placing the blank: Place the blank in the mold body 3; Step 5: Stamping: The stamping head 2 moves downward and cooperates with the mold body 3 to stamp the blank.

[0050] When installing the stamping head 2, the mating support block 23 on the mounting base 21 is sleeved on the mating support rod 136, and the mating support block 23 is in contact with the support block 135 to achieve the positioning of the stamping head 2.

[0051] When installing the mold body 3, the mold body 3 is sleeved onto the positioning column 151 through the positioning guide hole 31. The positioning of the mold body 3 is achieved through the cooperation between the positioning guide hole 31 and the positioning column 151.

[0052] Once the stamping head 2 and the mold body 3 are both positioned, the fixing operation can be achieved. That is, the screw 44 is rotated to move under the action of the thread, which in turn drives the drive plate 4 to move towards the mold body 3. As the drive plate 4 moves, the gear 5 will be driven to rotate under the action of the mating teeth 47. As the gear 5 rotates, the locking strip 52 on the gear 5 will be partially inserted into the locking cavity 33. The initial fixing of the mold body 3 is achieved through the cooperation between the locking cavity 33 and the locking strip 52.

[0053] As gear 5 rotates, the locking tooth hole 53 on the locking bar 52 aligns with the locking tooth post 61, thus freeing the locking tooth post 61 from restriction. At this time, the connecting ring 6 also becomes unrestricted. Under the action of the connecting spring 631, the connecting ring 6 moves upward, causing the locking tooth post 61 to be inserted into the locking tooth hole 53. The engagement between the locking tooth post 61 and the locking tooth hole 53 locks gear 5, preventing gear 5 from rotating. Consequently, gear 5 locks the drive connecting plate 4, ensuring the drive connecting plate 4 is in a stable state. This, in turn, guarantees the firmness and stability of the installation of the stamping head 2 and the mold body 3.

[0054] When the connecting ring 6 moves upward under the action of the connecting spring 631, the cooperation between the displacement channel 65 and the displacement post 72 will drive the movable locking post 7 to move towards the mold body 3, thereby allowing the movable locking post 7 to be inserted into the locking hole 32 on the mold body 3. In this way, the movable locking post 7 can further fix the mold body 3, ensuring the fixing strength of the mold body 3.

[0055] Furthermore, when the drive plate 4 moves towards the mold body 3, it will also drive the movable support block 8 to move synchronously. As the movable support block 8 moves towards the stamping head 2, it will drive the mating connecting bar 85 to move. Thus, as the mating connecting bar 85 moves, under the action of the connecting rod 87, it will drive the frame frame 9 to move upward. As the frame frame 9 moves upward, the support limiting post 92 on the frame frame 9 will be inserted into the limiting guide hole 22 on the mounting base 21. In this way, the cooperation of the support limiting post 92 and the limiting guide hole 22 can achieve... The fixing of the punch head 2, along with the upward movement of the frame 9, will cause the support plate 91 to contact the lower end face of the mounting base 21. In this way, the support plate 91 can further support the mounting base 21, ensuring the support strength of the punch head 2. When the movable support block 8 moves towards the punch head 2, it will also drive the L-shaped support plate 84 to move synchronously. As the L-shaped support plate 84 moves, it will contact the lower end face of the mounting base 21. In this way, the L-shaped support plate 84 can also provide auxiliary support for the punch head 2.

[0056] The stamping head 2 and the mold body 3 are very easy to install and remove, and can be fixed and unlocked simultaneously, which greatly facilitates the installation and removal of the two by the staff.

[0057] When it is necessary to replace the stamping head 2 and the mold body 3, push the connecting ring 6 downward to make the locking pin 61 on the connecting ring 6 disengage from the locking pin hole 53, so that the gear 5 is in the unlocked state. Then, rotate the screw 44 in the opposite direction to make it move under the action of the thread, thereby driving the drive plate 4 to move away from the mold body 3. As the drive plate 4 moves, it will drive the gear 5 to rotate in the opposite direction, thereby making the locking bar 52 disengage from the locking cavity 33. In addition, when the connecting ring 6 moves downward, it will also drive the movable locking pin 7 to disengage from the locking hole 32, thus making the mold body 3 in the unlocked state. As the drive plate 4 moves in the opposite direction, it will also drive the movable support block 8 to move in the opposite direction, thereby making the frame 9 move downward, thereby making the support limiting pin 92 disengage from the limiting guide hole 22, so that the stamping head 2 is in the unlocked state, which can realize the quick disassembly of the stamping head 2 and the mold body 3.
