Preferably, wherein set up the multiunit on work box 4 both sides and dodge groove 11, dodge groove 11 through the setting, be convenient for bear the base 5 and rotate, wherein dodge the shape of groove 11 can with bear the base 5 shape unanimity, the space enough bear the base 5 rotate can, excellent in use effect.

The working principle is as follows: when a foaming agent needs to be added into a refrigerator mould, firstly, a car body 1 with the refrigerator mould is moved into a working box body 4, a driving motor 701 rotates to drive a main gear 801 to rotate, when the main gear 801 rotates to drive a driven gear 802 to rotate, so that a driven lead screw 702 is driven to rotate by the driven gear 802 to drive two driving rods 703 to approach each other, so that a lifting plate 2 is driven to slide upwards through an adjusting support rod 704, when the lifting plate 2 slides upwards, a driving toothed plate 603 is driven to slide upwards, when the driving toothed plate 603 slides upwards, a transmission gear 602 is driven to rotate, specifically, the car body 1 rotates outwards, so as to drive a clamping plate 3 to rotate, after the clamping plate 3 is abutted by the inner wall of the working box body 4, the clamping plate 3 keeps a vertical state, so that the refrigerator mould is fixed, and the stability of the refrigerator mould during sliding is improved, the refrigerator mould is upwards transmitted to a set position on the working box body 4, and foaming agent adding operation is carried out; meanwhile, when the driving rods 703 approach each other, the connecting rod 901 is driven to slide, the connecting rod 901 drives the first wedge block 902 to slide, and after the first wedge block 902 abuts against the second wedge block 903 and then continues to drive the first wedge block 902 to slide, the first wedge block 902 drives the second wedge block 903 to slide downwards, so that the sliding rod 904 is driven to slide downwards, the fixing base 905 is driven to land downwards, and the stability of the vehicle body 1 is improved; after the foaming agent adding operation is completed, the driving motor 701 rotates reversely, the refrigerator mold slides downwards through the lifting plate 2, after the refrigerator mold slides to a set position, the vehicle body 1 slides out of the interior of the working box body 4, the refrigerator mold is clamped and moved away through clamping devices such as a mechanical arm, the driving motor 701 is started again before clamping, when the rotating shaft of the driving motor 701 rotates, the bearing base 5 is driven to rotate through the transmission assembly 6, the clamping plate 3 is not limited by the inner wall of the working box body 4, therefore, the bearing base 5 can be synchronously rotated along with the clamping plate 3, the refrigerator mold is far away from the clamping plate 3, the mold can be clamped into the next working flow through the mechanical arm conveniently, the working efficiency is improved, and the using effect is good.

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