Description

Technical Field

[0001] The utility model relates to the technical field of bridge rubber bearing production, in particular to a rubber bearing vulcanization device. Background Art

[0002] Bridge rubber bearings are made of multiple layers of rubber sheets and thin steel plates that are staggered, vulcanized and bonded. They have sufficient vertical rigidity to reliably transmit the pressure of the upper structure to the piers; they have good elasticity to adapt to the rotation of the beam ends; and they have a large shear deformation capacity to meet the horizontal displacement of the length and width directions of the upper structure.

[0003] After the rubber bearing is vulcanized, it needs to be demoulded. However, the existing vulcanization device is not convenient for demoulding.

[0004] The patent with publication number CN112693048A discloses a heating and vulcanizing mold for a laminated rubber bearing, including a mold body for heating and vulcanizing the laminated rubber bearing, wherein the laminated rubber bearing is composed of an upper flange plate, a lower flange plate, a plurality of rubber layers and a plurality of steel plate layers, wherein the plurality of rubber layers and the plurality of steel plate layers are alternately stacked and arranged between the upper flange plate and the lower flange plate, and the mold body includes a plurality of modules, wherein the plurality of modules cooperate with the upper flange plate and the lower flange plate to form a mold cavity, and a groove is provided on the inner end surface of the module, and a plurality of electromagnetic coils for heating the steel plate layer are installed in the groove.

[0005] The above patent adopts electromagnetic induction heating, which can evenly and quickly heat the steel plate layer in the laminated rubber bearing. The heat of the steel plate can be directly transferred to the rubber layer, thereby achieving high-speed vulcanization and effectively solving the problem of uneven vulcanization. However, the inventor found during use that the demoulding of the rubber bearing needs to be done on a demoulding machine (i.e., the mold is moved to the demoulding machine and fixed, and the demoulding machine is started to eject the rubber bearing) or the module is removed and then the electromagnetic coil is removed, and finally the insulating heat insulation board is removed to complete the demoulding. Both of the above methods have the disadvantages of cumbersome operation steps and low work efficiency.

[0006] Therefore, it is necessary to develop a rubber bearing vulcanization device to address the above defects. Utility Model Content
