In the figure: the device comprises a carrying pole type cross beam 1, a blocking cylinder 2, a stretching spring 3, a guide sleeve 4, a blocking connecting rod 5, an oil filling nozzle 6, a plug 7, a blocking opening 8, a connecting rod cantilever 9, a fish-eye joint 10, a plug 11 rotating cylinder, a universal ball bearing 12, a plug 13 rotating cylinder mounting seat, a connecting column 14 and a fixing plate 15.
Detailed Description
As shown in fig. 1, a shoulder pole type plug mechanism comprises two blocking cylinders 2 and a blocking connecting rod 5, wherein the blocking cylinders 2 are distributed on two sides of the blocking connecting rod 5, and the stress balance of the plug is ensured. The shoulder pole type cross beam 1 is in threaded connection with the end parts of the two blocking cylinders 2 through connecting columns 14, the two blocking cylinders 2 are longitudinally installed, a piston rod I faces upwards, a guide sleeve 4 is arranged in the middle of a blocking connecting rod 5, a plug 7 is connected to the end of the blocking connecting rod, high-temperature-resistant lubricating grease can be injected into the guide sleeve 4, the resistance of the plug 7 is reduced in the lifting and rotating process, and lifting and rotating actions of the plug 7 are smoother. One side of the two blocking cylinders 2 is provided with a plug rotating cylinder 11 which is horizontally arranged, the guide sleeve 4 is provided with an oil filling nozzle 6, high-temperature resistant lubricating grease is filled into the guide sleeve 4 through the oil filling nozzle 6 for lubrication, and resistance when the plug 7 is lifted and rotated is reduced. Two extension springs 3 are arranged below the shoulder pole type cross beam 1, one end of each extension spring 3 is fixed on the shoulder pole type cross beam 1, the other end of each extension spring 3 is fixed on a fixing plate 15, and two blocking cylinders 2 and guide sleeves 4 are further fixed on the fixing plates 15. The front end of a piston rod II of the plug rotating cylinder 11 and the plug connecting rod cantilever 9 move through a fish-eye joint 10, and the plug connecting rod cantilever 9 swings up and down along with the plug connecting rod 5, so that the plug rotating cylinder 11 is not influenced by the ascending and descending of the plug 7. When the plug cylinder 2 fails, the plug 7 has enough pressure to block the plug opening 8, so that the aluminum liquid cannot flow into the working chamber without limitation. The extension spring 3 that shoulder pole formula crossbeam 1 below even has guarantees to block up when cylinder 2 became invalid (if the cylinder damages, air supply atmospheric pressure is insufficient or the outage, the cylinder connection is not hard up), can effectually guarantee the downforce of end cap 7, does not make the aluminium liquid flow to the working chamber always.

The fixed end of the plug rotary cylinder 11 is linked by adopting a universal ball bearing 12, the front end of a piston rod of the plug rotary cylinder 11 is movably linked with the plug connecting rod cantilever 9 through a fish-eye joint 10, and the possibility of breakage of a guide rod is avoided. The plug rotating cylinder 11 is not influenced by the ascending and descending of the plug 7, can swing up and down along with the plug connecting rod 5, and the stress of the plug rotating cylinder 11 still keeps the straight line stress of the fixed point and the two points of the rod end while swinging, so that the piston rod II keeps straight line back and forth movement all the time, and the service life of the plug rotating cylinder 11 is prolonged. The plug rotary cylinder mounting seat 13 is provided with a universal ball bearing 12 which is fixed with the plug rotary cylinder 11.
The working process comprises the following steps:
1. the blocking cylinder 2 drives the plug 7 to move upwards, the plug 7 leaves the blocking opening 8, and a gap between the two chambers is opened;
2. the aluminum liquid in the standing chamber flows into the working chamber through a gap between the two chambers under the action of self gravity;
3. the aluminum liquid in the working chamber rises to a set liquid level;
4. the blocking cylinder 2 drives the plug 7 to move downwards, the plug 7 is attached to the blocking opening 8, and a gap between the two chambers is blocked;
5. the plug rotating cylinder 11 drives the plug 7 to rotate, so that the plug 7 and the blocking opening 8 are tightly attached;
6. the working chamber is filled with compressed air to press the aluminum liquid to enter the die cavity of the low-pressure casting machine through the liquid lifting pipe.
