Description

Technical Field

[0001] This utility model relates to the field of seismic isolation bearing technology, specifically a seismic isolation bearing mold structure. Background Technology

[0002] Seismic isolation bearings are a special type of structural support device. They are created by adding a seismic isolation layer between the superstructure and the foundation and installing rubber seismic isolation bearings to achieve a soft connection with the ground, thereby offsetting part of the seismic energy and reducing seismic damage. Rubber seismic isolation bearings are made by stacking rubber discs and circular steel plates.

[0003] During the manufacturing process of seismic isolation bearings, the stacked rubber discs and circular steel plates need to be vulcanized. Vulcanization requires a vulcanization mold, but existing molds are often integrally designed, making it difficult to open the mold after vulcanization. A press is needed for demolding, which can easily lead to product and mold scrapping. Therefore, we propose a new mold structure for seismic isolation bearings. Utility Model Content

[0004] To address the shortcomings of existing molds, which are difficult to open after vulcanization and require demolding with a press, easily leading to product and mold scrap, this utility model provides a vibration isolation support mold structure. It has the advantage that the first and second molds can be quickly demolded by removing the locking screw and locking nut, thus solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A seismic isolation bearing mold structure includes a first mold and a second mold, which are symmetrically placed to form a ring structure. Second ear plates are fixedly connected to the ends of the first mold and the second mold, and multiple openings are opened on the second ear plates from top to bottom. It also includes a top cover and a support base, which are located at the two ends of the first mold and the second mold, respectively. L-shaped side plates are symmetrically connected to the side wall of the support base. Multiple limiting plates are horizontally connected to the adjacent side of the L-shaped side plates, and the first ear plates are symmetrically connected to the side wall of the top cover. After the limiting plates are rotated and moved into the openings, the first ear plates, the second ear plates, the L-shaped side plates, and the limiting plates are locked together by locking screws, and locking nuts are tightened at the ends of the locking screws.

[0006] Optionally, an annular seat is fixedly connected to the top of the support base, and an annular groove coaxial with the annular seat is opened at the bottom of the first mold and the second mold.

[0007] Optionally, the base is fixedly connected to the bottom of the support.

[0008] Optionally, the bottom of the top cover is fitted with an extension seat coaxial with the first mold and the second mold. When the extension seat is located between the first mold and the second mold, the side wall of the extension seat is clearance-fitted with the inner wall of the first mold and the second mold.

[0009] Optionally, the top cover has a vent hole that extends through the extension seat.

[0010] Optionally, a first through hole is provided on the second ear plate, and a second through hole is provided on the L-shaped side plate and the limiting plate, with the locking screw connected through the first and second through holes.

[0011] Compared with the prior art, this utility model can seal the cavity formed by the first mold, the second mold, and the support base through the top cover, and can fasten the top cover, the first mold, the second mold, and the support base by the locking screw and the locking nut. After vulcanization treatment, the locking screw and the locking nut can be removed, and the first mold and the second mold can be rotated to quickly demold, which improves processing efficiency and extends the service life of the mold.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Reference Figures 1 to 4 This utility model provides a technical solution: a seismic isolation bearing mold structure, including a first mold 7 and a second mold 18. In use, the first mold 7 and the second mold 18 are placed symmetrically to form a ring structure, and second ear plates 10 are fixedly connected to the ends of both the first mold 7 and the second mold 18. Figure 3 , 4 As shown, it also includes a top cover 2 and a support base 6. The top cover 2 and the support base 6 are located at the two ends of the first mold 7 and the second mold 18, respectively. L-shaped side plates 8 are symmetrically connected to the side wall of the support base 6. Multiple limiting plates 9 are horizontally connected to the side of the L-shaped side plates 8. Multiple openings 5 ​​are opened from top to bottom on the second ear plate 10.

[0020] During installation, the first mold 7 and the second mold 18 are first placed on top of the support base 6. To improve the stability of the first mold 7 and the second mold 18 on top of the support base 6, an annular seat 15 is fixedly connected to the top of the support base 6, and an annular groove 17 coaxial with the annular seat 15 is opened at the bottom of the first mold 7 and the second mold 18. After placement, the first mold 7 and the second mold 18 are rotated, which can drive the limiting plate 9 to rotate and move into the opening 5, thereby limiting and fixing the position of the first mold 7 and the second mold 18.

[0021] like Figure 3 , 4 As shown, the first ear plate 4 is symmetrically connected to the side wall of the top cover 2. After the limiting plate 9 is rotated and moved into the opening 5, the first ear plate 4, the second ear plate 10, the L-shaped side plate 8, and the limiting plate 9 are locked together by the locking screw 1. The second ear plate 10 has a first through hole 13, and the L-shaped side plate 8 and the limiting plate 9 have a second through hole 14. The locking screw 1 is connected through the first through hole 13 and the second through hole 14, and the locking nut 12 is tightened at the end of the locking screw 1. By fixing the locking nut 12 and the locking screw 1, the first mold 7 and the second mold 18 can be fixed between the top cover 2 and the support base 6.

[0022] Meanwhile, to improve the stability of the support base 6, such as Figure 2 , 4As shown, a base 11 is fixedly connected to the bottom of the support 6, and an extension seat 16 coaxial with the first mold 7 and the second mold 18 is tightly attached to the bottom of the top cover 2. When the extension seat 16 is located between the first mold 7 and the second mold 18, the side wall of the extension seat 16 is in clearance fit with the inner wall of the first mold 7 and the second mold 18. A vent hole 3 is provided on the top cover 2 that penetrates the extension seat 16.

[0023] In summary, this seismic isolation bearing mold structure, during use, involves placing the rubber pads and steel sheets requiring vulcanization into the cavity formed by the first mold 7, the second mold 18, and the support base 6, and sealing it with the top cover 2. The locking screw 1 is then installed to secure the top cover 2, the first mold 7, the second mold 18, and the support base 6, and finally locked with the locking nut 12. After vulcanization, the locking screw 1 and the locking nut 12 are removed, and the first mold 7 and the second mold 18 are rotated, causing the limiting plate 9 to move out of the opening 5. This allows for quick demolding of the first mold 7 and the second mold 18, effectively improving processing efficiency and greatly facilitating operation.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
