Principle of operation

Firstly, an operator starts a hydraulic pump positioned below the frame 32, stops the equipment at a proper position, takes out a proper amount of raw materials and puts the raw materials into raw material ports at the centers of nine die shells 15 positioned on the surface of the upper template 19, and then continuously operates the hydraulic pump, so that hydraulic oil is injected into a liquid injection channel 54 through an oil injection flange pipe 28, and the liquid injection channel 54 positioned in the push rod hydraulic cylinder 26 is pushed to move;

the shifting of the liquid injection channel 54 pushes the switching block 22 at the inner side of the device to shift, at this time, because the generated pulling force is small, the switching block 22 can pull the supporting bottom plate 31 inwards under the action of the limiting slide block 53, meanwhile, as the support base plate 31 and the inner side of the upper sealing ring mold 20 are respectively provided with the support base plate fixing plate 37 and the upper mold plate fixing plate 24, and the supporting base plate fixing plate 37 and the upper plate fixing plate 24 are connected by a movable ring 38, the inward movement of the support base plate 31 will bring the upper gasket mold 20 inward, the carrying hanger 34 arranged outside the sealing ring mold 20 is hung outside the track rod 33, the track rod 33 is limited to move in the track of the upper template track 30, so that the sealing ring mold 20 gradually descends and is connected with the four positioning protrusions on the surface of the support base plate 31, and finally the sealing ring mold 20 is in contact with the surface of the support base plate 31;

when the supporting bottom plate 31 moves to the innermost side of the equipment and is blocked by the upward bulge on the inner side of the rack 32, as the hydraulic pump continuously injects hydraulic oil into the push rod hydraulic cylinder 26, the switching block 22 continues to keep the original movement direction, the limiting slide block 53 arranged on the surface of the switching column 51 is pressed into the switching column 51 under the pressure of the switching block 22, the switching block 22 is unlocked to continue to move and drives the connecting rod 12 arranged above the switching block 22 to move, the movement of the connecting rod 12 drives the sucker rod 11 to move so as to draw out the hydraulic oil in the top plate hydraulic cylinder 10 and press the top plate hydraulic rod 39 to descend, so that the pressure column 14 extends into the pressure die 16 and presses the raw materials in the die;

when the top plate hydraulic rod 39 continuously descends to a certain height, the limiting ring 36 arranged outside the pressing column 14 is in contact with the upper surface of the pressing die 16 and presses the pressing die 16 to sink, at the moment, the outer diameter of the circular groove of the pressing die shell 15, which is larger than the sealing ring mold 20, does not descend any more, the outer diameter of the pressing die 16, which is smaller than the inner diameter of the circular groove, can continuously descend and press the flash generated in the middle of the silica gel sealing ring, the pressing column 14 starts to go deep into the top plate 13 as the top plate hydraulic rod 39 continuously sinks and is blocked by the sealing ring mold 20, and starts to rotate under the action of the pressing column thread 41, and the pressing die 16 also starts to rotate as the linkage column 18 at the lower end surface of the limiting ring 36 is connected with the linkage hole 17 at the upper surface of the pressing die 16, so as to tear the flash of the silica gel sealing ring, and the pressing die shell 15 arranged outside the lower bottom surface of the pressing die 16 can simply polish the silica gel sealing ring in the process;

after pressing is completed, the hydraulic pump rotates reversely so that the push rod 25 backs up and therefore drives the switching block 22 to retreat, the switching block 22 slides a small section of the rear connecting rod 12 to abut against the switching block 22 and is driven by the switching block 22 to retreat so that the sucker rod 11 is pushed into the top plate hydraulic cylinder 10 to lift the top plate 13 through the top plate hydraulic rod 39, when the top plate 13 reaches a certain height, the switching block 22 starts to push the pull rod 21 to retreat and drive the supporting bottom plate 31 and the sealing ring mold 20 to retreat, when the sealing ring mold 20 retreats, the carrying hanger 34 outside the sealing ring mold 20 is hung outside the rail rod 33, so that the upper mold plate rail 30 is gradually lifted up, and at the moment, the top column 48 in the supporting bottom plate 31 loses pressure to lift up the sealing ring demolding module 47 in the sealing ring mold 20 to realize demolding.
