Problems solved by technology

[0008] Although the above-mentioned invention application proposes a method of speeding up heat transfer by punching holes in the support and inserting metal heat-conducting rods, it does not deviate from the central heat-conducting diffusion technology. During the process, the rubber close to the metal heat conduction rod melts excessively, and the rubber far away from the metal heat conduction rod is insufficiently vulcanized. At the same time, because there is a large amount of air between the rubber layer and the steel sheet, it is difficult to discharge the air during vulcanization, which greatly affects the molding of the rubber bearing. The final quality and seismic effect, vertical stiffness and vertical bearing capacity will all be affected

[0051] According to the specification requirements of the above-mentioned building laminated rubber bearings, a rapid vulcanization mold of a building laminated shock-isolation rubber bearing having the technical characteristics of the present invention is placed on a flat vulcanizing machine, the upper heating template 5 is opened, and the rubber sheet 13, Steel sheets 14 are alternately put into the building laminated shock-isolation rubber bearing mold, and then the heated inner mold 1 with heat conduction strips is put in...

Embodiment 2

[0056] Same as Example 1, but in consideration of the large volume and weight of the large-scale building laminated vibration-isolation rubber bearing mold, a combined mold structure is used, and the inner mold 1 is heated by a heat conduction strip, which is divided into eight modules at 45 degrees, and the outer mold is divided into eight modules. The radius of the circle is 85mm, and the radius of the inner circle is 15mm to form an inner hole, and a central positioning compression sleeve is added in the hole with a radius of 14.5mm. Keep a gap of 0.5mm with the hole, and insert the adjustment piece to make the module press the laminated steel sheet. Similarly, the annular heating outer mold 2 also adopts a module structure and has a guiding structure. Various known technologies can be used to make the module The laminated steel plates are pressed tightly to maintain good heat conduction, and the modular structure is conducive to the enlargement of the mold, while maintainin...

Embodiment 3

[0058] This example is a large-scale integrated large-scale building laminated shock-isolation rubber bearing, which omits two sealing steel plates, directly heats the connecting plate, and directly vulcanizes it as a part of the bearing, so as to simplify the process, reduce the cost and improve the bearing. Quality, the basic specifications of the support are: diameter 1000mm, height 635mm, film 40 layers, thickness 10mm, steel sheet 39 layers, thickness 4mm, the conventional process makes such a large support, it is difficult to evenly heat, and the center temperature rises slowly. After adopting the structure of the invention, the heat transfer speed is accelerated, and the edge and the center are heated almost simultaneously, which can effectively solve the contradiction between oversulfurization and undersulfurization simultaneously. Simple calculation shows that the heat conduction heat flux of the present invention reaches 1499w, which is 3.7 times higher than that of t...
