[0056] After the cutter 28 is running, the cutter 28 moves into the blade groove of the detector 31, and the detector 31 detects that the cutter 28 has completed the cutting process. After the detector 31 detects that the cutter 28 is reset again, the detector 31 controls the auxiliary mechanism 3 to continue the operation of the injection molding equipment;

[0057] When the second injection mold 22 is reset and cleaned, the arm cylinder 33 is started, the arm cylinder 33 drives the support frame 32 to rotate, and the support frame 32 drives the brush 310 and the push rod 312 to rotate, so that the brush 310 and the push rod 312 are attached to the first injection mold 21, so that the brush 310 is opposite to the injection groove of the first injection mold 21, and the push rod 312 is opposite to the injection port of the first injection mold 21. After the detector 31 detects that the cutter 28 is reset, the detector 31 controls the third electric push rod 311 to start, and the third electric push rod 311 drives the push rod 312 to move, so that the push rod 312 moves into the injection mold. The ejector rod 312 pushes out the residual material that may remain in the injection tube 25, and then after the ejector rod 312 is reset, the stepper motor 38 is started, and the stepper motor 38 drives the gear 36 to rotate, so that the gear 36 moves on the rack 35, so that the gear 36 drives the linkage frame 37 to move on the slide rail 34, and the linkage frame 37 drives the brush 310 to move, and at the same time the second electric push rod 39 is started, and the second electric push rod 39 drives the brush 310 to extend, so that the brush 310 is attached to the injection groove of the first injection mold 21, so that the injection groove of the first injection mold 21 is cleaned by the brush 310.
