At this time, the opening of the bottom mold 102 faces downward, and the foam glue in the bottom mold 102 separates from the bottom mold 102 under the action of gravity, thereby completing the automatic demolding effect of the foam glue, making the demolding of the foam glue faster and more convenient.

[0022] The mounting block 105 is fixedly mounted on the bottom mold 102, the rotating rod 106 is rotatably mounted on the fixed rod 104 and penetrates the fixed rod 104, the rotating rod 106 is fixedly connected to the mounting block 105, the driving assembly drives the rotating rod 106 to rotate, the upper mold 103 is a downward convex structure, the bottom mold 102 is a box structure with an opening facing upward, the mounting blocks 105 are in two groups and are symmetrically distributed on both sides of the bottom mold 102, the rotating rod 106 is in two groups and is distributed on the fixed rods 104 on both sides, the rotating rod 106 is connected to the mounting block 105, and the upper mold 103 is a downward convex structure, the bottom mold 102 is a box structure with an opening facing upward, the mounting blocks 105 are in two groups and are symmetrically distributed on both sides of the bottom mold 102, the rotating rod 106 is connected to the mounting block 105, and the rotating rod 106 is connected to the mounting block 105. The block 105 is welded, and the rotating rod 106 is rotatably installed on the fixed rod 104 through a bearing. The driving assembly enables the rotating rod 106 to have a better rotation effect. During demoulding, the driving assembly drives the rotating rod 106 on the left side to rotate, and at the same time, with the cooperation of the rotating rod 106 on the right side, the mounting block 105 and the bottom mold 102 are rotated 180 degrees. At this time, the opening of the bottom mold 102 faces downward, and the foam glue in the bottom mold 102 is separated from the bottom mold 102 under the action of gravity, thereby completing the automatic demoulding effect of the foam glue, making the demoulding of the foam glue faster and more convenient.

[0023] Secondly, the first gear 107 is fixedly mounted on the rotating rod 106; the active driving component drives the first gear 107 to rotate, and the first gear 107 coincides with the axis of the rotating rod 106. The active driving component enables the first gear 107 to have a better rotation effect.
