[0002] The plastic suction forming of the inner box of a refrigerator is a common technical means for forming the inner box of a refrigerator. The plastic suction mould for the inner box of a refrigerator uses a thermoplastic plastic sheet as the raw material. After heating it to make it soft, it is placed on a groove plate. Under the action of external force, it is evenly stretched, and through the movement of the mould, the sheet is stretched for the second time. Then, by pumping out the air between the sheet and the mould surface to form a vacuum, the sheet is completely adsorbed on the mould surface, and then cooled and shaped and demoulded to become the required part.

[0003] However, due to the lack of a device for quickly cooling and shaping in the existing vacuum plastic suction mould for the inner box of a refrigerator, the demoulding process is relatively complicated and time-consuming, greatly reducing the demoulding efficiency. At the same time, after the plastic suction of the inner box of a refrigerator is demoulded, there may be residues and the like attached to the inside of the mould box. When the mould is used again, problems such as poor plastic suction effect are likely to occur, which is not conducive to the vacuum plastic suction forming of the inner box of a refrigerator. Therefore, in order to solve the above problems, we need to design a vacuum plastic suction mould for the inner box of a refrigerator. Summary of the Utility Model:
