Through the cooperation of the plug hole 533 and the second plug post 511, the rear side of the plug plate 53 can be fixed relative to the base plate 51. The plug-in and pull-out structure at both ends of the plug plate 53 facilitates the installation and disassembly of the plug plate 53. After the foaming adhesive solidifies, it is convenient to discharge the refrigerator foam door panel.

[0027] Please see Figure 2-4A further solution based on this embodiment is as follows: A pressure plate 21 is provided above the workbench 1, and a guide post 22 is connected to the bottom of the pressure plate 21. The guide post 22 can pass through the workbench 1 and connect to the connecting plate 23 below the workbench 1. A cylinder 24 is provided below the connecting plate 23. The cylinder 24 is fixed relative to the support leg 11. The pressure plate 21 can restrict the foaming adhesive from overflowing from the foaming mold space formed by the plug plate 53, baffle 52, moving plate 2 43, bonding plate 454, and moving plate 1 34, thereby limiting the foaming adhesive. After the cylinder 24 drives the pressure plate 21 to rise, it can increase the convenience of the refrigerator foaming door panel discharge. The cylinder 24 can be fixed to the ground by expansion bolts, or a metal plate can be set at the bottom of the support leg 11, and then the cylinder 24 is fixed to the screw holes on the metal plate.

[0028] Please see Figure 1-3 A further solution based on this embodiment is: the top of the pressure plate 21 is provided with an injection port 211, into which expanding foam can be injected. By providing an injection port 211 on the top of the pressure plate 21, it is convenient for the expanding foam to enter, and a refrigerator foam door panel is formed under the limitation of the support structure.

[0029] Working Principle: This mechanism involves adjusting the support of the foaming mold, making it particularly suitable for the pre-fabrication of refrigerator foam door panels. This section uses the production of refrigerator foam door panels as an example to explain the principle of this structure. This structure is used for the pre-foaming treatment of refrigerator foam door panels to improve the efficiency of subsequent refrigerator door panel production and reduce foaming time. During subsequent door panel production, the refrigerator foam door panel produced by this mechanism is inserted into the engineering plastic of the refrigerator door panel. The empty spaces inside the refrigerator door panel are then filled with foam adhesive using a foam gun, reducing the time spent filling the refrigerator door panel with foam adhesive using a foam gun and improving efficiency. To improve the production efficiency of refrigerator door panels, when producing a single specification of foamed refrigerator door panel, the thickness of the foamed door panel remains unchanged; only the length and width dimensions are altered. The programmable controller drives the first and second reversible electric cylinders 31 and 41, moving the first and second moving plates 34 and 43 to appropriate positions. The second moving plate 43 then moves the insert rod 452, the spring-loaded block 451, and the bonding plate 454 left and right together. When the first moving plate 34 moves forward, it presses against the spring-loaded block 451, the bonding plate 454, and the insert rod 452. 2. Moving forward together, spring 453 is compressed here. When moving plate 1 34 moves backward, spring 453 will relax. Adhesive plate 454 and spring block 451 will continue to press against the front of moving plate 1 34. After moving plate 1 34 and moving plate 2 43 move to the appropriate position, cylinder 24 drives pressure plate 21 to move downward, covering the top of adhesive baffle 52, plug plate 53, moving plate 2 43, moving plate 1 34, and adhesive plate 454. Then, the foam gun on the robotic arm is aimed at injection port 211 and fills it with foam adhesive. Here, the adhesive plate 454 can fit the left side of the movable plate 43. After filling is completed and the refrigerator foam door panel has solidified, the cylinder 24 drives the pressure plate 21 to move upward. Then the worker prys out the plug plate 53. The reversing electric cylinder 31 drives the movable plate 34 to move backward, and the reversing electric cylinder 41 drives the movable plate 43 to move to the right. The worker uses a scraper to remove the internal refrigerator foam door panel. The reversing electric cylinder 41, the reversing electric cylinder 31, the cylinder 24 and the related programs, circuit connections and air circuit connections are all existing technologies. Their working principles will not be described in detail here.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
