Then the vacuum pump body 27 is controlled to extract the gas in the inner cavity of the hollow disk 24, so that the workpiece is vacuum-adsorbed at the bottom of the rubber bag 25, and the square tube 22 is lifted as a whole to complete the demoulding process, thereby improving the production efficiency of the workpiece. The dust filter 26 can prevent debris from being absorbed into the inside of the hollow disk 24, thereby ensuring the safety of the vacuum pump body 27.

[0024] As an implementation method in this embodiment, Figure 1-4 As shown, the boss 28 is fixedly installed on the front of the workbench 1, a stepper motor 281 is fixedly installed on the bottom of the boss 28, a rotating seat 282 is rotatably connected to the inner wall of the boss 28, the output shaft of the stepper motor 281 is fixedly connected to the bottom of the rotating seat 282, a telescopic cylinder 283 is fixedly installed on the top of the rotating seat 282, a connecting rod 284 is fixedly installed on the telescopic end of the telescopic cylinder 283, and one end of the connecting rod 284 away from the telescopic cylinder 283 is fixedly connected to the outer wall of the connecting sleeve 21, the main mold 11 is detachably connected to the top of the workbench 1, the top of the main mold 11 is movably plugged with a closed mold 12, and the top of the closed mold 12 is welded with a lifting ear 13.

The heat exchange rate between the material and the water body is improved through the design of the heat exchange wing 33. The material of the insulation layer 36 can be set to phenolic foam. Through the design of the insulation layer 36, the influence of the air temperature on the cold water temperature is reduced.
