Description

Technical Field

[0001] This utility model relates to the field of engineering component preparation technology, specifically to a vulcanization molding equipment for bridge bearing rubber pads. Background Technology

[0002] Bridge bearing rubber pads are core components connecting the superstructure and substructure of bridges, undertaking functions such as load transfer and vibration buffering. Vulcanizing the rubber pads can optimize their mechanical properties and meet the load-bearing and buffering requirements of bridge bearings. However, existing vulcanization equipment has a fixed vulcanization area inside the vulcanizing machine, which means that the rubber pads need to be unloaded and re-fed immediately after feeding and vulcanization. The entire process needs to be carried out step by step. In addition, the vulcanized material contains a lot of heat, and it takes a long time to cool down before it can be removed. As a result, the overall vulcanization operation of the rubber pads takes a lot of time and reduces vulcanization efficiency.

[0018] This utility model discloses a vulcanization molding equipment for bridge bearing rubber pads.

[0019] This utility model provides, for example Figure 1-3 The bridge bearing rubber pad vulcanization molding equipment shown includes a vulcanizing machine 1 and a vulcanization assembly. The vulcanization assembly includes an upper mold 2 and a lower mold 3. The upper surface of the lower mold 3 is provided with two molding templates 4 arranged in a horizontal manner. A hydraulic cylinder assembly 5 is fixed between the vulcanizing machine 1 and the upper mold 2. A connecting plate 6 is fixed between the two molding templates 4. A moving block 7 is fixed at the bottom of the connecting plate 6. An installation plate 8 is fixed on the surface of the vulcanizing machine 1. A reciprocating screw 9 is rotatably inserted inside the installation plate 8. A damping sleeve 18 is fixedly inserted inside the installation plate 8. The smooth end of the reciprocating screw 9 is rotatably disposed inside the damping sleeve 18. A support frame 10 is fixedly installed at the lower end of the outer wall of the vulcanizing machine 1. The end of the reciprocating screw 9 is rotatably disposed inside the support frame 10. The reciprocating screw 9 is configured to cooperate with the moving block 7. A moving and shifting mechanism for driving the reciprocating screw 9 to rotate in one direction is provided between the reciprocating screw 9 and the upper mold 2. The moving and shifting mechanism includes multiple ratchet teeth 11 arranged at intervals. A ratchet gear 12 is fixedly sleeved on the rod wall of the reciprocating screw 9. A connecting frame 13 is fixedly provided on the outer wall of the upper mold 2. The forming template 4 is staggered with the connecting frame 13. Multiple mounting frames 14 are fixedly arranged at intervals on the lower end of the outer wall of the connecting frame 13. The multiple mounting frames 14 are all arranged in a U-shape. The ratchet teeth 11 are located inside the mounting frames 14. A rotating rod 15 is rotatably passed through the inside of the mounting frame 14. The ratchet teeth 11 are fixedly sleeved with the rotating rod 15. A baffle 16 is fixedly provided on the lower end of the outer wall of the mounting frame 14. The baffle 16 is configured to cooperate with the ratchet teeth 11. A compression spring 17 is fixedly provided between the ratchet teeth 11 and the connecting frame 13. The ratchet gear 12 is configured to cooperate with the multiple ratchet teeth 11.

[0020] In order to effectively assist in cooling the rubber pad after vulcanization, such as Figure 1 As shown, two symmetrically arranged fixing plates 19 are fixedly installed on the upper part of the outer wall of the vulcanizing machine 1, and a cooling fan 20 is fixedly installed at the bottom of both fixing plates 19.

[0021] Working principle: In the initial state, both molding templates 4 are on the surface of the vulcanizing machine 1. One molding template 4 is located in the vulcanizing position directly below the upper mold 2, and the other molding template 4 is located in the non-vulcanizing position. The operator first fills the molding template 4 in the non-vulcanizing position with rubber raw material, and then starts the equipment. The hydraulic cylinder assembly 5 drives the upper mold 2 to move downward. The upper mold 2 gradually approaches the lower mold 3 and closes with the molding template 4 in the vulcanizing position. At this time, the vulcanizing machine 1 begins to vulcanize the rubber raw material in the molding template 4. During this process, when the upper mold 2 moves downward, it will drive the connecting frame 13 to move downward synchronously. The ratchet 11 in the mounting frame 14 below the connecting frame 13 contacts the ratchet 12 on the wall of the reciprocating screw 9. Since the downward direction of the upper mold 2 is opposite to the unidirectional driving direction of the ratchet 11, the ratchet 11 will rotate around the rotating rod 15 and compress the spring 17. At this time, the ratchet 12 does not rotate, the reciprocating screw 9 remains stationary, and the molding template 4 in the vulcanizing position stably carries out the vulcanizing operation. At the same time, the non-vulcanizing position can cool the rubber pad that has been vulcanized (the cooling fan 20 is started, and the fan below the fixed plate 19 blows air to cool the rubber pad) or prepare for the next material filling. Since the cooling fan 20 is set on both sides, it can effectively cool the internal components of the molding template 4 that move in both directions. After the rubber pad at the vulcanization position is vulcanized, the hydraulic cylinder assembly 5 drives the upper mold 2 to move upward away from the lower mold 3. The upper mold 2 drives the connecting frame 13 to move upward synchronously. At this time, the ratchet tooth 11 is reset under the elastic force of the compression spring 17, and the baffle 16 limits the ratchet tooth 11, so that the ratchet tooth 11 and the ratchet gear 12 are tightly meshed. During the upward movement of the upper mold 2, the ratchet tooth 11 drives the ratchet gear 12 to rotate in one direction. The ratchet gear 12 drives the reciprocating screw 9 to rotate synchronously under the support of the damping sleeve 18 and the support frame 10 in the mounting plate 8. Since the reciprocating screw 9 is set to cooperate with the moving block 7, the rotation of the reciprocating screw 9 will drive the moving block 7 to move laterally back and forth along the axis of the reciprocating screw 9. The moving block 7 drives the two forming molds through the connecting plate 6. The plate 4 is synchronously transversely rotated (because the moving block 7 cooperates with the reciprocating screw 9, and the connecting plate 6 is fixed to the moving block 7, and the connecting plate 6 is fixedly connected to the two forming templates 4, so that when the moving block 7 moves to the rightmost end of the reciprocating screw, the left forming template 4 moves to the working area, and as the reciprocating screw 9 continues to rotate, the moving block 7 moves back, so that the right forming template 4 moves back to the working area, thus completing the transverse rotation of the two forming templates 4. At the same time, because the connecting frame 13 and the forming template 4 are staggered front and back, the forming template 4 will not be obstructed during the transverse movement). The forming template 4 that was originally in the vulcanization position moves to the non-vulcanization position, and the forming template 4 that was originally in the non-vulcanization position moves to the vulcanization position directly below the upper mold 2. Subsequently, the hydraulic cylinder assembly 5 drives the upper mold 2 to move down and close the mold, vulcanizing the raw material in the new vulcanizing position forming template 4. At the same time, the non-vulcanizing position can be used for material removal and filling. This cycle is repeated to realize that the two forming templates 4 can alternately perform vulcanization operations and auxiliary operations, which greatly shortens the overall vulcanization process time and improves vulcanization efficiency.

[0022] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
