[0024] Among them, the guide plate 1, the mold closing hook seat 6 and the cylinder 7 are on the same horizontal line; the specific connection relationship between the mold closing hook seat 6 and the cylinder 7 is: the mold closing hook seat 6 is installed at the end of the piston rod of the cylinder 7 and is locked with a nut to prevent loosening; the locking nut 10 is a thin locking nut; the connecting plate 9 is L-shaped.

[0025] The use state of the present invention is: Figure 1 and Figure 2 This is a schematic diagram of the action of the present invention. The movable end of the cylinder 1 7 is extended, and the mold clamping hook seat 6 moves together with the mold clamping hook 3 toward the guide plate 1. The mold clamping hook 3 opens after contacting the hook guide plate 1. When the mold clamping hook 3 is completely in contact with the guide plate 1, the cylinder 1 7 reaches the extension stroke limit and remains, so that the two mold clamping hooks 3 remain in the open state.

[0026] When opening the mold, Figures 3 to 5 , the power switching from cylinder 1 7 to cylinder 2 11: first, cylinder 2 11 is in the follow-up state, cylinder 1 7 pushes the mold clamping hook seat 6 to move the guide plate 1, and after reaching the extension stroke limit, it switches to the follow-up mode, the two mold clamping hooks 3 are disengaged from the model mounting base plate 12 and remain in the open state, the cylinder 2 11 releases the follow-up state and performs the extension action, pushing the model mounting base plate 12 to continue to open until the stroke limit;

[0027] When closing the mold, Figures 6 to 8, the power switching from cylinder 2 11 to cylinder 1 7: first, cylinder 1 7 is in the following state, cylinder 2 11 retracts, driving the model mounting base plate 12 to contact with the mold clamping hook seat 6, and the hydraulic buffer 8 slows down the side impact at the moment of contact. When the mold clamping hook 3 gradually leaves the guide plate 1 and completely hooks the model mounting base plate 12, cylinder 2 11 is converted to the following state, cylinder 1 7 is released from the following state and performs the retraction action, and continues to drive the model mounting base plate 12 until the model clamping is completed.
