The engraving block 3 moves away from the upper fixed block 2 and slides into the through groove 101 through the cooperation of the screw 5 and the slide groove 4 to separate the engraving block 3 from the mold body 1 and replace the engraving block 3.

[0023] like Figure 2 and Figure 5As shown, a hollow tube 6 is provided on the mold body 1, and the highest point of the hollow tube 6 does not exceed the sliding plane of the imprinting block 3 and the mold body 1, thereby ensuring that the imprinting block 3 can be horizontally moved to the space of the through groove 101, and the hollow tube 6 is provided below the upper fixed block 2, and the distance between the hollow tube 6 and the lower fixed block 21 is the thickness value of the imprinting block 3. This distance is set to ensure that the imprinting block 3 remains in contact with the lower fixed block 21 while the upper fixed block 2 can limit the top of the imprinting block. A limiting rod 7 is provided for sliding in the hollow tube 6, and the bottom of the limiting rod 7 is A spring 8 is provided between the end and the hollow tube 6. When the spring 8 is in normal state, the upper end of the limiting rod 7 extends outward from the outside of the hollow tube 6. The limiting rod 7 extends outward from the outside of the hollow tube 6 to limit the engraving block 3 to prevent it from automatically moving into the through groove 101 after being squeezed, thereby ensuring the working stability of the engraving block 3. At the same time, through the setting of the limiting rod 7, the engraving block 3 is ensured to be accurately positioned during installation, avoiding engraving quality problems caused by position offset, thereby further improving the installation accuracy and stability of the engraving block 3, and ensuring the consistency and high quality of the engraving.

[0027] When the engraving block 3 needs to be replaced, by pressing the connecting plate 10 downward, the connecting plate 10 drives the L rod 9 to move downward, and the L rod 9 pulls the limiting rod 7 to move downward along the hollow tube 6 and compresses the spring 8. When the limiting rod 7 moves down to the inner cavity of the hollow tube 6, the limit on the engraving block 3 is released. At this time, the screw 5 is loosened and moved along the slide groove 4 in the direction away from the upper fixed block 2, thereby driving the engraving block 3 to slide into the through groove 101. Then, the connecting plate 10 is released. Under the action of the spring 8, the limiting rod 7 is reset upward, thereby separating the engraving block 3 from the upper fixed block 2. The engraving block 3 can be pulled out of the through groove 101 to achieve the engraving block 3 and the mold body 1. Convenient separation; insert the engraving block 3 that needs to be replaced into the through groove 101, then move the engraving block 3 in the direction of the lower fixed block 21, and drive the limit rod 7 to move downward by moving the connecting plate 10 downward. When the screw 5 at the top of the engraving block 3 slides into the slide groove 4, tighten the screw 5 so that the screw 5 abuts against the upper fixed block 2, thereby fixing the engraving block 3, and then release the connecting plate 10, and the limit rod 7 is reset, thereby further providing a limit for the engraving block 3, thereby preventing the engraving block 3 from shifting toward the through groove 101 after being pressed down by the pressing plate, thereby ensuring the stability of the engraving block 3 and the engraving effect, thereby realizing convenient replacement of the engraving block 3.
