[0006] A horizontal plate is arranged on the bottom plate between the horizontal beam and the vertical beam; wherein one end of the horizontal plate of the upper mold is formed with a convex arc surface extending downward and partially matching the arc surface of the door panel of the entrance door, and one end of the horizontal plate of the lower mold is also formed with a concave arc surface extending downward and partially matching the arc surface of the door panel of the entrance door;

[0007] A panel is arranged on each horizontal plate, and the panel is in contact with the surface of the horizontal plate; and a flexible foam board in contact with the curved surface of the panel is arranged on the panel at the convex curved surface end of the horizontal plate of the upper mold and on the panel at the concave curved surface end of the horizontal plate of the lower mold.

[0008] Preferably, the total thickness of the transverse plate and the panel is less than the height of the transverse beam and the vertical beam.

[0009] Preferably, the panel is an aluminum plate.

[0010] Preferably, the flexible foam sheet is a flexible polyurethane foam.

[0011] Preferably, the cross beams, vertical beams, cross plates and panels are all fixed to the base plate by countersunk screws.

[0012] Preferably, adhesive is coated between the flexible foam board and the transverse board.

[0013] The beneficial effects of the utility model are:

[0014] After comprehensive consideration of design calculations and factors such as compression deformation of door panels, appropriate sizes of the convex and concave arc surfaces of the horizontal panel are obtained, and flexible foam boards (the foam boards are elastic) are used on the arc surfaces of the horizontal panels to ensure that the door panels and the arc surfaces of the bonding tooling can fit tightly when the door panels are pressure cured during bonding, and then the door panels can be evenly stressed when pressure is applied, thereby improving the reliability of bonding and ensuring the bonding quality of the door panels.
