During the assembly of the refrigerator, if you want to turn the direction of the refrigerator, you can control the lifting platform 1 to rise, push the refrigerator upward, and then turn the refrigerator. The turntable 5 between the refrigerator and the lifting platform 1 provides conditions for the refrigerator to turn. When it is turned to a suitable position, the lifting platform 1 is controlled to descend, and the refrigerator is placed back on the placement platform 2. A rubber pad 7 is provided on the top of the turntable 5, and the rubber pad 7 is connected to the turntable 5. The rubber pad 7 can increase the friction between the turntable 5 and the refrigerator to prevent the turntable 5 from sliding or shifting during the process of carrying the refrigerator to rotate.

[0034] A telescopic frame 301 is provided on one side of the two placement platforms 2 away from the lifting platform 1. An electric push rod is provided inside the telescopic frame 301, and the electric push rod is connected to the telescopic frame 301.

An injection molding machine body 305 is arranged on the side of the telescopic frame 301 away from the placement table 2, and the injection molding machine body 305 is connected to the injection molding tube 304 through a connecting pipe 306.

[0035] When it comes to the step of injection molding and foaming, if the foaming injection port is facing upward, the operator can directly control the telescopic frame 301 to retract.

[0040] The refrigerator to be assembled is placed on the placement table 2 , and an operator can assemble the refrigerator on the placement table 2 .

[0041] When it comes to the step of injection molding and foaming, if the foaming injection port is facing upward, the operator can directly control the telescopic frame 301 to retract. The contraction of the telescopic frame 301 will drive the rotating rod 302 to descend, and the injection tube 304 will move downward with the rotating rod 302. At this time, the operator can insert the injection tube 304 into the foaming injection port of the refrigerator, start the injection molding machine body 305 to output the foamed plastic, and thus perform foaming injection molding on the refrigerator.
