And a connecting rod 13 is rotatably connected to the arc-shaped baffle plate 12, a pull rod 14 is rotatably connected to one end, far away from the arc-shaped baffle plate 12, of the connecting rod 13, a plug 18 is slidably connected to the sliding cylinder 1, and one end, far away from the connecting rod 13, of the pull rod 14 is fixedly connected with the plug 18.
The lower extreme fixed connection of plug 2 has iron to scrape the ring 17, inlays on the inner wall of slide tube 1 and is equipped with multiunit solenoid 25, and multiunit solenoid 25 is from last to equidistant distribution down, and adjacent two sets of solenoid 25 interval is 10 cm.
The side wall of the push plug 2 is provided with a vibration groove 19, a vibration power generation sheet 20 is embedded in the vibration groove 19, the vibration power generation sheet 20 is electrically connected with the solenoid 25 through a conductive mechanism, and a vibration mechanism for vibrating the vibration power generation sheet 20 is installed in the vibration groove 19. The conductive mechanism comprises a first conductive plate 23 and a second conductive plate 24, wherein the first conductive plate 23 is embedded on the side wall of the plunger 2 and electrically connected with the vibration generating piece 20, and the second conductive plate 24 is embedded on the inner wall of the sliding cylinder 1 and electrically connected with the solenoid 25.

It should be noted that, the weight rod 21 can be made of a material with a relatively high density, such as lead, which has a relatively high mass and a relatively high inertia, and when the plunger 2 is pushed by the spring rod to move downwards and reset, the weight rod 21 cannot move downwards along with the plunger 2 synchronously under the inertia, so that the vibration power generating piece 20 on the upper side is pressed, and the vibration power generating piece 20 is made of a piezoelectric material and can generate a current when being pressed mechanically, and in addition, an amplifying circuit is arranged between the vibration power generating piece 20 and the first conductive plate 23 to amplify the generated current, and when the first conductive plate 23 contacts the second conductive plate 24, the amplified current can be transmitted to the corresponding solenoid 25, so that the solenoid 25 is energized and generates a relatively strong magnetic force.
In the present invention, the molten metal flows into the first flow path pipe 7 first in communication with the exhaust system used in the background art. When the molten metal reaches the inside of the sliding cylinder 1 and between the lower sides of the push plugs 2, air between the molten metal and the push plugs 2 expands and is discharged outwards from the exhaust ports 15 on the two sides of the sliding cylinder 1. Therefore, the air does not push the plunger 2 to move upwards, and when the molten metal flows to the lower side of the arc-shaped baffles 12 and continues to flow upwards, the two arc-shaped baffles 12 are turned outwards by the flowing molten metal, so that the two pull rods 14 can be pushed to move outwards through the connecting rods 13, the pull rods 14 can pull the plugs 18 to enter the exhaust ports 15, and the plugs 18 can block the exhaust ports 15. When the molten metal flows into the sliding cylinder 1, the metal pushes the push plug 2 to move upwards, and the molten metal cannot flow out of the exhaust port 15. The plunger 2 will also push the spring rod 4 to move upwards, so that the left end of the pressure rod 5 moves upwards and the right end moves downwards, and push the valve rod 11 and the valve core 10 to move downwards, so as to block the upper end of the second flow passage pipe 8, and prevent the metal liquid from flowing into the exhaust valve cylinder 6 after the air in the cavity is discharged from the second flow passage pipe 8, the exhaust valve cylinder 6 and the exhaust pipe 9.
Therefore, in summary, in the invention, when the molten metal does not reach the inside of the sliding cylinder 1 and the lower side of the push plug 2, the air between the push plug 2 and the molten metal can be exhausted through the exhaust port, so that the push plug cannot be pushed to move, and therefore, the exhaust valve cylinder 6 cannot be closed in advance, so that the air in the cavity of the mold can be fully exhausted, and the cavity of the processed product caused by bubbles in the cavity is avoided.
After production is finished, after the molten metal in the sliding cylinder 1 flows out of the first flow passage pipe 7, the push plug 2 moves downwards under the action of the spring on the spring rod 4. Under the inertia effect, the weight lever 21 cannot move downwards along with the push plug 2 so as to press the vibrating power generation piece 20 on the upper side, the vibrating power generation piece 20 is forced to generate mechanical deformation to generate current, when the first conductive plate 23 is contacted with the second conductive plate 24 on the uppermost side, the generated current is amplified by the amplifying circuit and then is led into the solenoid 25 which is connected to the uppermost side, the solenoid 25 is powered on to generate magnetism and attract the iron scraping ring 17 to drive the push plug 2 to move upwards for a certain distance, then the weight lever 21 stops pressing the vibrating power generation piece 20, the solenoid 25 on the uppermost side is powered off and does not attract the iron scraping ring 17, so that the spring lever 4 continues to push the push plug 2 to move downwards, at the moment, the weight lever 21 continues to press the vibrating power generation piece 20 under the inertia effect, meanwhile, the second conductive plate 24 on the middle part of the inner wall of the sliding cylinder 1 is contacted with the first conductive plate 23, so that the solenoid 25 on the middle part is powered on, in turn, will attract the iron scraper ring 17 up a small distance. Similarly, the solenoid 25 for the lowermost side will also turn on and off and attract the ferrous scraper ring 17 upward a small distance.
Therefore, after the device is produced, under the action of the conductive mechanism, the vibration mechanism, the solenoid 25 and other components, the push plug 2 and the iron scraping ring 17 on the upper side of the push plug move up and down for many times, the iron scraping ring 17 quickly scrapes off the molten metal remained on the inner wall of the sliding cylinder 1 and discharges the molten metal through the first flow channel pipe 7, and the molten metal is prevented from being cooled and formed on the inner wall of the sliding cylinder 1, so that the sealing performance between the inner wall of the sliding cylinder 1 and the push plug 2 is influenced.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
