During demolding, the driving assembly 324 drives the first extension 3221 and the second extension 3222 to leave below the arc-shaped convex portion 3122.

[0038] Please refer to Figures 9-10 As shown, the working principle of the interlocking paving brick forming device 200 of this embodiment:

[0039] When mold clamping and pouring are required, the mold frame component 3 fits above the bottom plate. The brick mold frame 311 and the bottom plate enclose to form a molding cavity for the interlocking paving brick 100. The driving assembly 324 drives the first extension 3221 and the second extension 3222 to extend below the arc-shaped convex portion �122. After pouring the raw material, the pressing head component 4 presses down to cover the upper mold cavity 312. At this time, the first extension 3221, the second extension 3222 and the lower mold cavity 313 cooperate to form the brick base 2, and the upper mold cavity 312 forms the brick lock block 1. When demolding is required, the pressing head component 4 rises and the upper mold cavity 312 opens. The driving assembly 324 drives the push plate 321 to slide, driving the first extension 3221 and the second extension 3222 to leave below the arc-shaped convex portion 3122. In this way, the first extension 3221 and the second extension 3222 will not interfere with the demolding of the arc-shaped convex portion 3122. Then the mold frame component 3 moves upward as a whole by a distance of at least the height of one interlocking paving brick 100, so that the interlocking paving brick 100 completely leaves the brick mold frame 311 and is located on the bottom plate, that is, the demolding of the interlocking paving brick 100 is completed.
