After the molding is completed, the punch 21 moves away from the die 22, and the first pressure cover 31 is separated from the punch 21. The first driving member 4 then passes through the processing base 1 and the die 22 to drive the second pressure cover 32 to move away from the die 22 to realize demolding.

[0036] Specifically, see Figure 2 and Figure 3In one embodiment of the utility model, the matching portion 321 further includes a spring 321f, and the spring 321f is connected to the side wall of the installation slot 321c and the block 321b.
