The mold opening detection device 400 clamps the upper mold and moves upwards to separate the upper mold from the lower mold, the lower mold is driven by the second driving mechanism 330 to move to the manipulator 700, and the manipulator 700 detects and picks up the workpiece in the lower mold. Meanwhile, the mold opening detection device 400 clamps the upper mold and moves downwards to enter the cleaning mechanism 500, so that the upper mold is detected and cleaned, and the upper mold moves upwards to the highest point after the detection and cleaning are finished. Thereafter, the lower die moves to the position above the cleaning mechanism 500 along with the second driving mechanism 330, the rotating mechanism 340 drives the lower die to turn 180 degrees and back down, and the first driving mechanism 310 drives the lower die to move downwards to the cleaning mechanism 500, so that the detection and cleaning of the lower die are realized. And after cleaning, the lower die is turned over again to be in a flat state and ascends. If any one of the upper die and the lower die has a fault such as a breakage, a crack or the like, the upper die moves downwards to enable the fault die to be re-clamped, the conveying device 300 conveys the fault die to a position between the first die bearing plate 110 and the third die bearing plate, and the first die pushing mechanism 120 pushes the fault die to the fault die platform 600. The transporting device 300 moves to the second mold receiving plate 210 again, receives the spare mold pushed out by the second mold pushing mechanism 220, and transports the spare mold to the mold opening detection device 400 and the cleaning mechanism 500 for detection and cleaning, so that the manipulator 700 puts the raw material again and completes mold closing and pushing into the hearth.

The above is only the part or the preferred embodiment of the present invention, no matter the characters or the drawings can not limit the protection scope of the present invention, all under the whole concept of the present invention, the equivalent structure transformation performed by the contents of the specification and the drawings is utilized, or the direct/indirect application in other related technical fields is included in the protection scope of the present invention.
