After demolding and cleaning are finished, the hydraulic cylinder 2 can be opened through control, at the moment, the hydraulic cylinder 2 can drive the upper template 5 on the mounting plate 4 to move downwards through the hydraulic rod 3, at the moment, the connecting wire 7 moves downwards, the threaded rod 11 on the fixed coil 10 can be driven to rotate reversely under the action of the scroll spring 35 in the limiting frame 34, the connecting wire 7 can be wound, meanwhile, the fixed ejector rod 13 on the sliding plate 12 can be driven to move downwards, the demolding plate 17 is driven to move downwards to the original position and is separated from the fixed ejector rod 13, meanwhile, the downward movement of the sliding plate 12 can drive the lower powerful magnetic block 19 to gradually get away from the upper powerful magnetic block 20, at the moment, the reset spring 23 can be combined to drive the cleaning plate 22 to return to the original position, when the upper powerful magnetic block 20 moves outwards, the piston 25 can be driven to move outwards in the fixed pipe 28 through the fixed rod 24, at the moment, the baffle 27 can be pushed to rotate inwards under the action of air pressure, and the piston 25 of the through hole 26 is opened, so that the storage box 29 is not adversely affected, and the next work and use are facilitated.

To sum up: the invention has the beneficial effects that the device is improved on the basis of the prior art.

According to the invention, when the upper template 5 moves upwards, the threaded rod 11 can be driven to rotate through the connecting wire 7 and the fixed coil 10, so that each fixed ejector rod 13 on the sliding plate 12 can be driven to move upwards and push the stripping plate 17 to move upwards stably, the automatic stripping work can be conveniently and quickly completed in the process of mold splitting, and meanwhile, the damage to an aluminum alloy formed part when a follow-up worker uses a tool to strip the aluminum alloy formed part can be effectively prevented.

The device can drive the lower powerful magnetic block 19 upward movement of both sides when sliding plate 12 upward movement, and then can attract the last powerful magnetic block 20 of both sides simultaneously to middle motion, and drive clearance board 22 through connecting rod 21 and carry out automatic promotion clearance work to remaining raw materials debris in lower bolster 16, and can drive piston 25 on the dead lever 24 inward movement in fixed pipe 28 when the last powerful magnetic block 20 of both sides simultaneously to middle motion, can effectively increase the atmospheric pressure in the storage box 29, and then can carry the water in the storage box 29 to the small-size shower nozzle 33 department on the coupling hose 32 through linking up pipe 30, and spray in clearance board 22 department, and then can effectively strengthen the clearance effect, effectively improved the work efficiency of device.

The present invention is not limited to the above preferred embodiments, and any modifications, equivalent replacements, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
