[0023] As shown in Figure 3 and Figure 4 , the transmission assembly comprises a first bevel gear 9 fixedly connected to the bottom of the screw rod 6, the first bevel gear 9 is engaged with a second bevel gear 10 on one side, the two second bevel gears 10 on the same side are fixedly connected with a rotating shaft 11, the transmission box 4 inner cavity bottom is fixedly connected with a supporting plate 12, the rotating shaft 11 both ends penetrates through the supporting plate 12 and is rotatably connected therewith, the rotating shaft 11 side wall is provided with a driving member. By setting the transmission assembly, the screw cylinder 5 on the four corners can be driven synchronously, thereby driving the lower mold to rise synchronously, adjusting the distance between the two side molds to an appropriate distance, thereby adapting to the processing of different parts, and also can be used on the press body 1 with shorter stroke, high flexibility and good stability.

[0024] As shown in Figure 3 and Figure 4 , the driving member comprises a worm wheel 14 fixedly connected to the side wall of the rotating shaft 11, two worm wheels 14 are engaged with a worm 13 on the lower side, the other end of the worm 13 penetrates through the transmission box 4 and is fixedly connected with a hexagonal block 15, the worm 13 is rotatably connected with the transmission box 4. By setting the worm 13 for providing transmission force for the screw rod 6, and the worm wheel 14 and the worm 13 have self-locking function, which can further improve the stability of the whole and reduce the influence caused by vibration when the hydraulic drive unit 2 runs.

[0025] As shown in Figure 2 and Figure 5 , the through hole 16 side wall is fixedly connected with two limiting blocks 17, the screw cylinder 5 side wall is provided with two limiting grooves 18, the limiting blocks 17 and the limiting grooves 18 are slidably connected.
