In actual use, the upper die holder 2 and the lower die holder 1 are separated, the second plate 302 is pulled upwards to rotate to a first state, then the second plate 302 drives the supporting rod 13 to translate in a direction away from the first plate 301 through the linkage block 14 and the linkage groove 15, the supporting rod 13 stretches the first elastic piece 16 to elastically stretch and store elastic potential energy, the supporting rod 13 drives the sliding block 17 to move in the sliding groove 18, and the sliding block 17 extrudes the limiting block 20 to chamfer to smoothly pass through and automatically limited, so that the second plate 302 can be automatically kept in the first state, and the first die cavity 5 is restored to be horizontal and complete; after the rubber raw materials are placed, under the automatic control of equipment, the upper die holder 2 drives the upper die plate 6 to descend, the upper die plate 6 drives the swing rod 22 to descend, and the swing rod 22 drives the roller 23 to approach the butt joint 24; before the upper die plate 6 is attached and abutted with the lower die plate 3, the roller 23 enters the sliding groove 18 through the abutting joint 24, and as the upper die holder 2 continues to descend, the roller 23 is pushed by the swing rod 22 to slide in the sliding groove 18, the roller 23 can press the limiting block 20 first and then abut against the sliding block 17, and at the moment, the upper die plate 6 is just attached and abutted with the lower die plate 3, so that the hot working of the rubber ring can be performed; after the rubber ring is processed, the upper die holder 2 drives the upper die plate 6 and the swing rod 22 to ascend, so that demolding of the rubber ring and cutting of the flash can be performed, meanwhile, the swing rod 22 drives the roller 23 to slide in the sliding groove 18 to be close to the direction of the opposite joint 24 and keeps pressing the limiting block 20, then the elastic potential energy of the first elastic piece 16 is released, the supporting rod 13 is pulled, the sliding block 17 which is limited by the limiting block 20 can move along with the roller 23 in a fitting way, and in the process, the supporting rod 13 does not drive the second plate 302 to rotate through the linkage block 14 and the linkage groove 15, namely the second plate 302 still keeps a first state, so that the flash cutting is facilitated; after the flash is cut, the sliding block 17 moves along with the roller 23, so that the stay bar 13 corresponds to the bending change position of the linkage groove 15, the upper die holder 2 continues to rise, the stay bar 13 drives the roller 23 to slide continuously to approach the butt joint 24, so that the stay bar 13 drives the second plate 302 to start to rotate downwards, namely the second plate 302 moves in a second state, and therefore the rubber ring can be conveniently taken; finally, the upper die holder 2 drives the roller 23 to leave from the butt joint 24 through the stay bar 13, and one-time rubber ring processing is completed.
A heat-resistant rubber ring processing technology is based on heat-resistant rubber ring processing equipment, and rubber strip raw materials are filled into a first die cavity 5; the upper die plate 6 descends to be attached to the lower die plate 3 so that the second die cavity 10 is in butt joint with the first die cavity 5, the butt joint table 4 is embedded between the two seal rings 8, and the butt joint table 4 is communicated with glue overflow holes 11 on the seal rings 8; the rubber strip raw material is heated and pressurized to be melted, and then overflows to the overflow groove 9 through the overflow hole 11; after the rubber cools, the upper die plate 6 is lifted again to be separated from the lower die plate 3 so as to automatically cut off the formed rubber ring and the flash.
While certain exemplary embodiments of the present application have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that modifications may be made to the described embodiments in various different ways without departing from the spirit and scope of the application. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive of the scope of the application, which is defined by the appended claims.
