[0035] When in use, a filter is installed in the recovery tank 506 through a card slot, and an auxiliary cleaning and recovery mechanism can be added through the recovery tank 506 to increase the functionality of the molding mold.

[0036] For example, Figure 3 As shown, the utility model also includes: a card slot 301 corresponding to the card block 402 is opened on the top of the turntable 3, a push block 302 is slidably connected to the periphery of the card block 402 in the card slot 301, an air cushion 303 is gluingly connected to the periphery of the push block 302 in the card slot 301, and an air nozzle 304 is threadedly connected to the outer surface of the turntable 3, and the air outlet end of the air nozzle 304 is connected to the air cushion 303.
