after the left slider and the right slider are matched with the fixed die, the left cutting edge and the right cutting edge respectively collide with the left side and the right side of the parting surface of the fixed die, the parts of the fabric positioned at the two sides of the fixed die core back-off structure are cut, and the cut fabric excess materials are locally connected with the parts of the fabric positioned in the injection molding cavity;
the part of the fabric in the left fabric stitching area is stitched between the left slider and the fixed die, and the part of the fabric in the right fabric stitching area is stitched between the right slider and the fixed die.
Step four, after the injection molding is finished, the injection molding piece and the part of the fabric in the injection molding cavity are combined into a whole;
firstly, the slide block driving mechanism drives the left slide block and the right slide block to respectively withdraw towards two sides;
secondly, the injection molding machine drives the movable mold to move, the movable mold and the fixed mold complete mold opening, the cloth hanging needle is separated from the fabric, the fabric excess and the injection molding piece are left on the fixed mold and are ejected out together by an ejection mechanism of the fixed mold;
and finally, after the mechanical arm takes the part, manually cutting off the fabric excess material on the injection molding part, and putting the fabric excess material into a waste material barrel for recycling.
