In one embodiment, the fixing base 610 has a connection port 612, the connection port 612 is communicated with the receiving groove, and the hydraulic unit 400 can be used for pumping hydraulic oil so that the hydraulic oil flows into the receiving groove from the connection port 612, and the hydraulic oil is accumulated to provide a continuous upward supporting force to the piston 620, thereby pushing the piston 620 to move. In one embodiment, the fixing mechanism further includes a driving unit 300, and the driving unit 300 can drive the hydraulic unit 400 to draw hydraulic oil. Specifically, the driving unit 300 may be a motor, more preferably an asynchronous motor, and the hydraulic unit 400 may be driven to extract hydraulic oil by the rotation of the driving unit 300, so as to extract the hydraulic oil into the accommodating groove and push the piston 620 to move, thereby clamping the clamping member 630. In one embodiment, the clamping unit 600 includes a sealing ring 670, and the sealing ring 670 is sleeved on the connecting member 650 to seal a gap between the connecting member 650 and the fixing base 610. That is, when the hydraulic unit 400 draws hydraulic oil to push the piston 620 to move, the sealing ring 670 may prevent hydraulic oil from flowing out from a gap between the connection member 650 and the fixing seat 610.

The manometer is connected in the oil pump, not only can detect the output pressure of oil pump, and this pressure value can clearly be embodied in the manometer simultaneously to make the user carry out real time supervision to this pressure value. On one hand, when the user detects that the pressure value is too low, the driving force of the hydraulic oil pushing the piston 620 is insufficient, which easily causes the clamping member 630 not to stably clamp the first mold 40, and at this time, the user can set the output pressure of the oil pump, so as to timely supply pressure to the clamping member 630. On the other hand, when the user detects that the pressure value is too high, the impact of the hydraulic oil on the piston 620 is too large, which easily causes the clamping force of the clamping member 630 to clamp the first mold 40 to be too large, and the structure of the first mold 40 is damaged, and at this time, the user can perform reduction adjustment on the output pressure of the oil pump so as to prevent the pressure supply to the clamping member 630.

Specifically, the detection member 700 may preset an upper limit pressure value and a lower limit pressure value, the detection member 700 detects the clamping pressure of the clamping member 630 during the clamping of the first mold 40, and when the detection member 700 detects that the pressure value reaches the upper limit pressure value, the controller 800 may control the motor to stop working and close the valve of the oil pump, so that the pressure value of the clamping member 630 is in a stable state, that is, the clamping member 630 is in a pressure maintaining state. When the pressure value reaches the offline pressure value detected by the detecting member 700, the controller 800 can control the motor to start, open the valve of the oil pump, and recover the pressure supply to the clamping member 630, so as to avoid the first mold 40 from loosening and further causing danger in the production process of the die-casting device 10 due to insufficient pressure.
