Description

Technical Field

[0001] This utility model relates to the field of rubber products technology, and in particular to a rubber support ring and mold for an accumulator capsule. Background Technology

[0002] An accumulator is an energy storage device in a hydraulic or pneumatic system. Figure 1 This is a schematic diagram of the internal structure of an accumulator, including a tank 1 and a capsule 2 located inside the tank 1. The tank 1 has an inflation valve 11 and an oil valve 12 at both ends, with the inflation valve 11 connected to the capsule 2. The principle is as follows: when the system pressure increases, oil enters the tank 1, compressing the gas inside the capsule 2 until the system pressure stops rising; when the system pressure decreases, the capsule 2 expands, pushing the oil back into the circuit, thus mitigating the pressure drop. The problem is that the capsule 2 lacks stable support and buffer protection during expansion. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a rubber support ring and mold for an accumulator capsule. The rubber support ring can provide stable support and cushioning protection for the accumulator capsule.

[0004] In order to achieve the purpose of this utility model, the following solution is proposed: An accumulator capsule rubber support ring includes a rubber ring and a metal ring.

[0005] The rubber ring is frustoconical in shape, with a first groove at its center and a second groove located below the first groove. The inner diameter of the first groove is larger than the inner diameter of the second groove, forming a step between the two. The metal ring is placed on the step. The metal ring is used to install the rubber support ring inside the accumulator. The bottom of the rubber ring is concave to support the capsule.

[0006] Furthermore, the inner diameter of the metal ring is smaller than the inner diameter of the second groove, and the outer diameter of the metal ring is larger than the inner diameter of the first groove.

[0007] Furthermore, the outer wall of the rubber ring is provided with an arc-shaped groove.

[0008] A mold for preparing the rubber ring includes a main upper mold, a main lower mold, a secondary upper mold, and a secondary lower mold arranged coaxially, forming an injection area. The main upper mold is located above the main lower mold, and the secondary upper mold is located above the secondary lower mold. Both the secondary upper mold and the secondary lower mold are located inside the main upper mold and the main lower mold. The bottom surface of the main upper mold corresponds to the recess at the bottom of the rubber ring. The outer wall of the secondary upper mold corresponds to a second groove, and the outer wall of the secondary lower mold corresponds to a first groove. There is a gap between the outer wall of the secondary upper mold and the top surface of the secondary lower mold for pre-placing a metal ring. The inclined wall of the main lower mold corresponds to the outer wall of the rubber ring.

[0009] The beneficial effects of this utility model are as follows: by installing the rubber support ring inside the accumulator, the rubber support ring can effectively protect the accumulator capsule through elastic support, buffering and shock absorption, stress dispersion and friction reduction, etc., extend the service life of the capsule, and ensure the safe and reliable operation of the accumulator. Attached Figure Description

[0010] Figure 1 A schematic diagram of the internal structure of an energy storage device in the background art is shown; Figure 2 A cross-sectional view of the rubber retainer ring is shown; Figure 3 A cross-sectional view of the mold for the rubber retainer ring is shown. Detailed Implementation

[0011] Example 1 like Figure 2 As shown, this embodiment provides a rubber support ring for an accumulator capsule, including a rubber ring 31 and a metal ring 32.

[0012] Specifically, the rubber ring 31 is frustoconical in shape, and a first groove 311 and a second groove 312 are provided at the center of the rubber ring 31. The first groove 311 is located above the second groove 312, and the inner diameter of the first groove 311 is larger than the inner diameter of the second groove 312, forming a step between the two. The metal ring 32 is placed on the step.

[0013] Specifically, the inner diameter of the metal ring 32 is smaller than the inner diameter of the second groove 312 so that the metal ring 32 can be easily clamped onto the air valve 11 or the oil valve 12, thereby installing the rubber support ring inside the accumulator; the outer diameter of the metal ring 32 is larger than the inner diameter of the first groove 311, that is, the outer wall of the metal ring 32 is embedded in the solid of the rubber ring 31, which can further strengthen the connection between the metal ring 32 and the rubber ring 31.

[0014] Specifically, the bottom of the rubber ring 31 is concave. During use, the rubber support ring is installed... Figure 1 Inside the accumulator, usually located at the upper and lower ends of capsule 2, the concavity of rubber ring 31 helps to support capsule 2 more stably.

[0015] Specifically, the outer wall of the rubber ring 31 is provided with an arc-shaped groove 313, which is equivalent to the buffer opening of the rubber ring 31 itself.

[0016] When capsule 2 expands, the rubber ring can provide stable support and prevent capsule 2 from being damaged due to excessive deformation; the rubber ring can prevent capsule 2 from directly contacting tank 1 or other parts during high pressure or frequent movement, avoiding wear or tear; the rubber ring 31 of the rubber ring has a certain elasticity and cushioning performance, which can absorb the impact and vibration generated during the movement of capsule 2 and reduce fatigue damage to capsule 2; the rubber ring can also play a certain sealing auxiliary role to prevent gas or liquid leakage.

[0017] In summary, the rubber support ring effectively protects the accumulator capsule 2 by providing elastic support, buffering and shock absorption, dispersing stress, and reducing friction, thereby extending the service life of the capsule 2 and ensuring the safe and reliable operation of the accumulator.

[0018] Example 2 like Figure 3 As shown, this embodiment provides a mold, including a main upper mold 41, a main lower mold 42, a secondary upper mold 43 and a secondary lower mold 44 arranged coaxially, and a glue injection area 45 is formed between these four, which is used to inject glue to form the rubber ring 31 described in Embodiment 1.

[0019] Specifically, the main upper mold 41 is located above the main lower mold 42, and the secondary upper mold 43 is located above the secondary lower mold 44. Both the secondary upper mold 43 and the secondary lower mold 44 are located inside the main upper mold 41 and the main lower mold 42. The bottom surface of the main upper mold 41 corresponds to the recess at the bottom of the rubber ring 31. The outer wall of the secondary upper mold 43 corresponds to the second groove 312 of the rubber ring 31, and the outer wall of the secondary lower mold 44 corresponds to the first groove 311 of the rubber ring 31. There is a gap between the outer wall of the secondary upper mold 43 and the top surface of the secondary lower mold 44, which is used to pre-place the metal ring 32. The inclined wall of the main lower mold 42 corresponds to the outer wall of the rubber ring 31.

[0020] Specifically, there is an overflow groove 46 between the bottom surface of the main upper mold 41 and the main lower mold 42, and there is a mold release opening 47 between the outer wall of the main upper mold 41 and the outer wall of the main lower mold 42.

Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
