Description

TECHNICAL FIELD

[0002] The refrigerator shell is a cavity with a relatively complex structure. Therefore, the used mold frame is the most expensive component in the assembly production line. The mold frame supports the preform and the liner of the shell to bear the pressure generated by foaming. During the foaming process of the refrigerator shell, the shell needs to be transported, and a corresponding mold is selected to close the foaming opening of the refrigerator shell. Selecting an appropriate driving mode and operation method during the foaming operation of the refrigerator shell can not only improve the efficiency of the refrigerator foaming operation but also reduce the cost.

[0044] The lower die assembly 22 comprises a sliding groove arranged in the supporting frame 21, the lower die shell 221 is slidably arranged in the sliding groove, the reset spring rod is arranged between the lower die shell 221 and the inner wall of the sliding groove, the lower die bottom plate 222 is slidably arranged in the lower die shell 221, and the supporting spring rod is arranged between the lower die bottom plate 222 and the lower die shell 221.

[0048] The control assembly 42 includes a control hole opened at the upper end surface of the mounting rack 1, the control hole and the docking frame 32 are connected through a contraction air bag 421, and the control hole is connected with a first air pipe 422 at one end of the gas pump 41.

[0049] The execution assembly 43 includes an execution mounting hole opened on the mounting rack 1, a second air pipe 431 is mounted in the execution mounting hole, the second air pipe 431 is connected with the gas outlet, the second air pipe 431 is provided with a three-way valve 432, the three-way valve 432 is an electric valve, the three-way valve 432 is connected with an execution air bag 433, the execution air bag 433 is connected on the supporting frame 21, and an execution spring rod is arranged between the supporting frame 21 and the inner wall of the mounting rack 1;

[0050] When the refrigerator shell is placed, first control the air pump 41 to start working, the air pump 41 works in this state to extract the gas in the execution air bag 433, and inject the extracted gas into the contraction air bag 421, first the air pressure in the contraction air bag 421 starts to increase, the contraction air bag 421 first extrudes the docking frame 32 in the process of expansion, the docking frame 32 moves from top to bottom after being extruded, while the air pressure in the execution air bag 433 decreases, the supporting frame 21 moves to the position capable of working with the docking forming unit 3 under the action of the execution spring rod, the supporting frame 21 remains stationary after moving to the working position, at this time the air pump 41 continues to work, the docking frame 32 continues to move downward under the action of the contraction air bag 421, the docking frame 32 at this time exerts pressure on the positioning assembly 23, so that the positioning assembly 23 can fix the supporting frame 21 on the mounting rack 1 in work.

[0052] By adopting the above technical scheme, the execution frame 434 is driven to move in the execution sliding groove through the execution adjusting plate 435 during the movement of the supporting frame 21 in specific work process, the execution frame 434 abuts against the inner walls on both sides of the execution sliding groove when the supporting frame 21 moves to the working position, and the supporting frame 21 abuts against the inner wall on the other side of the execution sliding groove when the supporting frame 21 returns to the initial state, the position of the execution frame 434 is limited to determine the state of the supporting frame 21, so that the supporting frame 21 can accurately move in position.

[0053] As shown in Figure 1 , 11 -12, in order to ensure the stability of the supporting frame 21 working at the specified position, the limiting piece includes a limiting cylinder 436 mounted on the outer wall of the mounting rack 1, a limiting work frame 437 is mounted on the limiting cylinder 436, limiting support frames are uniformly arranged on the lower end face of the limiting work frame 437, and limiting locking rods 438 matched with the limiting locking holes are uniformly arranged on the limiting support frames.

[0059] After the foaming operation of the refrigerator shell is completed, the limiting part is first controlled to reset. After the limiting part is reset, the air pump 41 is controlled to operate in reverse. At this time, the air flow in the shrinkage air bag 421 is injected into the execution air bag 433 by the air pump 41. In this process, the pressure inside the shrinkage air bag 421 is reduced. The butt joint frame 32 is driven by the supporting telescopic rod 31 to move upward from bottom to top. In the movement, the positioning assembly 23 is reset, and the butt joint frame 32 is pushed to move toward the initial position during the expansion of the execution air bag 433.

[0065] By adopting the above technical scheme, in the specific operation process, when the supporting frame 21 returns to the initial state and is locked by the fixed support chain, the three-way valve 432 is started to close the communication state between the execution air bag 433 and the second air pipe, and the third air pipe 445 is communicated with the second air pipe 431 at the same time. At this time, the gas flow output by the gas pump in the operation flows into the moving cavity through the third air pipe 445, and the moving piston rod 442 starts to drive the execution operation frame 443 to move under the action of the gas flow pressure. The execution operation frame 443 drives the rack 444 and the driven gear 244 to cooperate with each other to control the rotation of the cam disc 243 on the rotating shaft 242 in the movement process.
