Description

Technical Field

[0001] The utility model relates to the field of rubber shock-isolating bearing manufacturing, in particular to a manufacturing mold for the rubber shock-isolating bearing. Background Art

[0002] Rubber seismic isolation bearings are a special structural support device, whose main purpose is to reduce the vibration and damage of building structures during earthquakes. Specifically, it is achieved by adding an 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 earthquake energy and reducing earthquake damage. Building seismic isolation rubber bearings can be mainly divided into natural rubber seismic isolation bearings and lead rubber seismic isolation bearings. Natural rubber seismic isolation bearings are made of superimposed rubber discs and circular steel plates, while lead rubber seismic isolation bearings insert a lead core between the rubber disc and the circular steel plate to improve the damping ratio and increase early stiffness.

[0003] In order to manufacture the rubber disc required for the lead rubber isolation bearing, a manufacturing mold for the rubber isolation bearing is required.

[0004] The current manufacturing mold of rubber seismic isolation bearings is mainly composed of an upper mold, a lower mold and a middle mold. The middle mold is placed between the upper mold and the lower mold to produce a rubber disc with a circular hole in the center. However, in actual use, the operator may forget to place the middle mold between the upper mold and the lower mold, resulting in the rubber disc being unusable, causing economic losses. On the other hand, the current manufacturing mold of rubber seismic isolation bearings usually directly pours the molten rubber matrix into the lower mold. There is often a certain amount of air in the lower mold, which may cause bubbles to appear inside the rubber disc produced, resulting in a decrease in the product quality of the rubber disc. Therefore, a manufacturing mold for rubber seismic isolation bearings is proposed to solve the above problems. Utility Model Content

The movement of the anti-fool pillar 6 will drive the rectangular block 9 to move together. The rectangular block 9 and the return spring 10 make the outer side of the anti-fool pillar 6 be received into the interior of the upper mold 2 when the force is not applied, and the inner side protrudes and fixes the upper groove 5. The top of the anti-fool pillar 6 is provided with a slot 11 for convenient card connection.

[0035] Reference Figure 1-Figure 3 The top of the lower die 1 is fixedly connected to a limit seat 12. The limit seat 12 is provided with four groups, which are evenly distributed in a ring shape at the top of the lower die 1 and are opposite to the position of the anti-fool column 6. A limit groove 13 is provided inside the limit seat 12. The inner wall of the top of the limit groove 13 is elastically connected to the limit block 15 through a limit spring 14. The limit spring 14 is provided with two groups, which are symmetrically arranged on both sides of the limit block 15. One end of the limit spring 14 is fixedly connected to the inner wall of the top of the limit groove 13, and the other end of the limit spring 14 is fixedly connected to the top of the limit block 15. When the limit block 15 is not subjected to force, the limit spring 14 will push the limit block 15 to move downward, and the limit block 15 will be pushed outward. The upper mold 2 is fixedly connected to the top of the limit block 15, and a pulling component for conveniently releasing the limit is fixedly connected to the top of the limit block 15. The connecting column 17 is slidably connected to the top of the limit block 15. The connecting column 17 is slidably connected to the top of the limit seat 12. When the connecting column 17 moves, the limit block 15 is driven to move. A pull ring 18 is fixedly connected to the top of the connecting column 17, and the pull ring 18 connects four groups of connecting columns 17 at the same time.

[0036] Reference Figure 2 and Figure 4A feed valve 19 is arranged at the top of the upper mold 2. Four groups of feed valves 19 are arranged, which are evenly distributed in a ring shape at the top of the upper mold 2, so as to facilitate the uniform injection of rubber masterbatch. An exhaust valve 20 is arranged inside the lower mold 1. Two groups of exhaust valves 20 are arranged, which are symmetrically arranged on the left and right sides of the lower mold 1. A sliding sleeve 21 is fixedly connected inside the lower mold 1. Eight groups of sliding sleeves 21 are arranged, which are evenly distributed in a ring shape inside the lower mold 1. A sliding circular groove 22 is opened inside the sliding sleeve 21. The inner wall of the bottom end of the sliding circular groove 22 is elastically connected to the limiting cylinder 24 through a support spring 23. When the limiting cylinder 24 is not subjected to force, the support spring 23 will push the limiting cylinder 24 to move upward. The support spring 23 is The end is fixedly connected to the top of the sliding groove 22, and the other end of the support spring 23 is fixedly connected to the bottom of the limiting cylinder 24. The outer circumference of the limiting cylinder 24 is slidably connected to the inside of the sliding groove 22. The sliding groove 22 limits the limiting cylinder 24 to only slide up and down along the inner wall of the sliding groove 22. A sealing round block 25 with good sealing performance is fixedly connected to the top of the limiting cylinder 24. The outer circumference of the sealing round block 25 is slidably connected to the inside of the lower mold 1, and the inside of the sealing round block 25 is slidably connected to the outer circumference of the middle mold 4. When the upper mold 2 is placed on the lower mold 1, the top of the sealing round block 25 contacts the upper mold 2 to reduce the original air inside the lower mold 1. A handle groove 26 is provided at the top of the upper mold 2 for easy lifting.

[0037] Working principle: When you want to install the upper mold 2, first place the middle mold 4 in the fixed lower groove 3, and then align the fixed upper groove 5 at the bottom of the upper mold 2 with the top of the middle mold 4 and place it downward. At this time, the top inclined surface of the side of the middle mold 4 will squeeze the anti-fool column 6. When the middle mold 4 completely enters the fixed upper groove 5, the anti-fool column 6 pops out from the side wall of the upper mold 2, and pulls up the pull ring 18 at the same time. The pull ring 18 drives the card block 16 to pop out through the connecting column 17 and the limit block 15, and squeezes the limit spring 14 at the same time. When the popped-up anti-fool column 6 enters the inside of the limit seat 12, release the pull ring 18, and the limit spring 14 resets, driving the card block 16 to be connected to the inside of the card groove 11. When the middle mold 4 is not installed, the anti-fool column 6 inside the upper mold 2 cannot pop out, and the upper mold 2 cannot be fixed, thereby preventing the middle mold 4 from being forgotten to be installed. When you want to reduce the bubbles inside the rubber disc, the rubber masterbatch is transported inward through the feed valve 19, the rubber masterbatch enters the interior of the lower mold 1, and squeezes the sealing round block 25. The sealing round block 25 is squeezed downward by the rubber masterbatch, driving the limiting cylinder 24 to move downward and squeeze the supporting spring 23. The supporting spring 23 pushes the sealing round block 25 upward, making the rubber inside the rubber disc tighter. At the same time, the air under the sealing round block 25 is discharged from the exhaust valve 20, thereby reducing the bubbles inside the rubber disc.
