[0034] The upper die moving assembly 4 is disposed on the top of the workbench 11 .

[0035] The bottom of the workbench 11 is fixedly connected with four supporting legs for support and fixation. The workbench 11 and the support plate 12 are fixedly connected through the demoulding assembly 3. The side mold 2 is square in shape. The size of the demoulding frame 31 can just fit the inner surface of the side mold 2 completely. The connecting blocks 32 are U-shaped and there are two of them. One end of the two connecting blocks 32 is fixedly connected to the top of the left and right ends of the demoulding frame 31. The bottoms of the two passive telescopic rods 33 pass through the interior of the workbench 11 and are fixedly connected to the top of the support plate 12, and the surfaces of the tops of the two passive telescopic rods 33 pass through the interiors of the two connecting blocks 32 and are fixedly connected to the inner surfaces of the tops of the two connecting blocks 32 respectively.
