The large mold opening machine according to claim 2, characterized in that: The mold clamping mechanism (43) is provided with a front clamping plate (431), a rear clamping plate (432) and a clamping oil cylinder (433); the front clamping plate (431) is connected to the front mounting plate of the sliding box (41) via a set of guide shafts (434); the rear clamping plate (432) is connected to the rear mounting plate on the sliding box (41); and the clamping oil cylinder (433) is provided on one side of the rear mounting plate and is connected to the rear clamping plate (432).

4. The large-scale mold opening machine according to claim 1, characterized in that: The hook (617) is provided with a hook body, the upper part of the hook body is provided with a mounting hole, the lower part is provided with a hook body, the hook body is clamped on the top of the hammer shaft (614), and the upper part of the hook body is connected to the end of the piston rod of the die cylinder (613).

5. The working method of the large-scale mold opening machine according to claim 1, characterized in that: The specific working method is as follows: 1): First, place the mold on the slide (411), and move the slide cylinder to fix the mold; 2): Then align the die opening gap on the die with the die opening punch (616), that is, let the slide cylinder drive the slide (411) to move forward and backward, and the punch (616) moves up and down under the drive of the die cylinder (613), and the two cooperate with each other; 3): After the die opening is aligned with the punch (616) in the previous step, the die is passed through the die cylinder (613) to the outer circle of the die; 4): Then adjust the stroke of the micro-motion cylinder (619) according to the actual needs of production; 5): After the micro-motion cylinder (619) is adjusted, the pressure wheel cylinder (621) descends, the pressure wheel cylinder (621) drives the guide rod (622), and the guide rod (622) drives the pressure wheel (623) to move downward, move to the mold, and press the mold opening; 6): Loosen the movable slide cylinder until the end face of the mold is 2 / 3 of the length, and adjust the stamping amount of the mold opening device (61) to the required amount for processing; 7): Then select automatic mold opening or manual mold opening through the control device as needed; 8): When automatic mold opening is selected, the number of times the punch (616) impacts the mold is set first, and then the control device controls the die cylinder (613) and the micro-motion cylinder (619) to descend to drive the punch (616) to impact the mold. When the micro-motion cylinder (619) rises, the roller (42) is driven by the roller drive mechanism to drive the mold to rotate; 9): When the mold rotates to a suitable angle along with the roller (42), the steps in step 8) are repeated, that is, the control device controls the die cylinder (613) and the micro-motion cylinder (619) to descend and drive the punch (616) to impact the mold until the mold is completely opened; 10): When manual mold opening is selected in step 7), the solenoid valve is activated to lower the micro-movement cylinder (619), and then the solenoid valve is activated to allow the punch (616) to impact the mold, and the solenoid valve is activated to raise the micro-movement cylinder (619), and the solenoid valve is activated to allow the roller (42) to drive the mold to rotate; 11): When the mold is rotated to the appropriate position, repeat the steps in step 10), that is, the solenoid valve is activated to lower the micro-motion cylinder (619), and the solenoid valve is activated again to allow the punch (616) to impact the mold, and the solenoid valve is activated to raise the micro-motion cylinder (619). The solenoid valve is activated to allow the roller (42) to drive the mold to rotate until the mold is fully opened.
