The invention has the beneficial effects that:

(1) according to the new energy automobile shell casting device, the inserting rod is driven to move upwards through the baffle, the piston is driven to move upwards in the circular cavity when the inserting rod moves upwards, the piston pushes gas in the circular cavity to be extruded into the air cavity through the inclined hole when moving upwards, the gas in the air cavity pushes the rubber plug to move upwards in the circular groove, the upward moving rubber plug pushes the push rod to move upwards, the push rod pushes the push plate to move upwards, the push plate moves outwards from the inside of the clamping groove when moving upwards, and then the push plate pushes a casting in the mold groove out of the mold groove, so that the casting can be conveniently taken out from the space between the mold and the mold groove.

(2) According to the new energy automobile shell casting device, the fixed block is rotated to drive the soft threaded strip to rotate, the soft threaded strip moves towards the inner part of the round pipe when the soft threaded strip rotates and is pushed by the extrusion of the threaded cylinder, the soft threaded strip pushes the push block to move in the round pipe, the push block pushes casting materials accumulated in the round pipe to be discharged, and therefore the casting materials in the round pipe are prevented from being solidified to block the round pipe, and the automobile shell casting operation cannot be continued.

(3) According to the new energy automobile shell casting device, the pressure rod is driven to move upwards when the mold moves upwards, the pressure rod is pushed to move downwards by the pressure plate after the pressure rod is contacted with the pressure plate, the arc plate is pushed to move out of the arc groove when the pressure rod moves downwards, and the arc plate presses the casting adhered to the mold, so that the casting is prevented from being attached to the surface of the mold and being inconvenient to take.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the embodiments and descriptions given above are only illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the claims. The scope of the invention is defined by the appended claims and equivalents thereof.
