[0041] ​​​​​In specific use, first, the automatic trigger sheet 17 is triggered upward by the handle 18 to make the automatic trigger sheet 17 separate from the micro-shift component shell 16, and then the polyurethane paint is sprayed into the micro-shift component shell 16 and the bottom of the upper mold 20. Then the automatic trigger sheet 17 is buckled into the micro-shift component shell 16, so that the automatic trigger sheet 17 is below the extrusion balloon 6, the installation of the automatic trigger sheet 17 is completed, the upper mold 20 and the lower mold 19 are closed, and the driving motor 27 is started at this time to make the driving gear 26 rotate, the C-shaped guide 30 is driven to rotate through the guide teeth 33, and then the rotating disc 31 rotates. When the driving gear 26 moves to the bending change point 34, the guide teeth 33 at the bending change point 34 make the driving gear 26 move upward or downward, and then the driving gear 26 moves upward and downward along the waist-shaped groove 25 under the guidance of the moving slider 24. When the driving gear 26 moves past the bending change point 34, it continues to rotate along the guide teeth 33 inside or outside the C-shaped guide 30 to make the C-shaped guide 30 rotate reversely, thereby driving the rotating disc 31 to rotate reversely, and then the rotating support table 4 is synchronously rotated through the shaft of the rotating disc 31 to make the upper mold 20 and the lower mold 19 rotate synchronously, so as to realize mold shaking, improve the polyurethane foaming effect, and make the foaming material foam more uniformly. In the process of rotating the upper mold 20 and the lower mold 19, the automatic trigger sheet 17 slides on the inner wall of the micro-shift component shell 16 due to its own gravity. At this time, after the mold shaking is completed, the upper mold 20 and the lower mold 19 return to the horizontal position, the foaming process starts, the foaming material expands in volume and drives the automatic trigger sheet 17 to slide upward. When the automatic trigger sheet 17 moves to contact the extrusion balloon 6, the foaming material no longer expands, and then the automatic trigger sheet 17 presses the extrusion balloon 6 to make the water in the extrusion balloon 6 enter the injection valve 9 through the conveying shell 7. The injection valve 9 opens to make the water in the extrusion balloon 6 enter the micro-shift operation container 13 through the injection valve 9 and the conveying hole 11. The remaining water is conveyed to the plurality of micro-shift operation containers 13 through the plurality of conveying holes 11 to combine with the water-absorbing resin particles 14. Then the plurality of water-absorbing resin particles 14 absorb water to expand. In the process of waiting for the polyurethane foaming material to be formed, the plurality of water-absorbing resin particles 14 also expand to be formed and contact the micro-shift partition layer 12. The water remaining on the expanded water-absorbing resin particles 14 makes the micro-shift partition layer 12 melt. Then the expanded water-absorbing resin particles 14 move outward from the plurality of micro-shift moving holes 15. The plurality of water-absorbing resin particles 14 apply force to the formed polyurethane foaming material from a plurality of positions on both sides of the polyurethane foaming material to help the soft polyurethane foaming material after being formed to separate from the micro-shift component shell 16, so as to facilitate taking out the formed foaming material from the lower mold 19.In the foaming process, when the automatic trigger sheet 17 has not contacted the extrusion balloon 6, the unsoluble micro-shift layer 12 does not affect the foaming process, and when the automatic trigger sheet 17 presses the extrusion balloon 6, the micro-shift layer 12 is gradually dissolved, providing the automatic separation effect of the foaming material during the foaming forming process, saving manpower; due to the limiting effect of the upper mold 20, after the automatic trigger sheet 17 contacts the upper mold 20 during the foaming process, the foaming process also stops, helping the polyurethane foaming material to foam and form.
