Description

Technical Field

[0001] This utility model relates to a rubber gasket sealing performance testing device, belonging to the field of sealing test technology. Background Technology

[0002] Rubber, as an important industrial material, is widely used and plays a crucial role in various fields such as the automotive, electronics, pharmaceutical, construction, and aerospace industries due to its unique elasticity and resistance to various media. Before being put into use, rubber products must undergo rigorous performance testing to ensure that their dimensions, structure, and resistance to various media meet specific application requirements.

[0003] In the performance testing of rubber products, dimensional and appearance inspection is a fundamental and essential step, and can usually achieve 100% measurement accuracy using specialized testing equipment. For rubber gaskets used in high-pressure environments, their sealing performance is particularly critical. Sealing tests not only verify the rationality of the product's structural design but also verify the appropriateness of the rubber material selection. Therefore, how to more closely simulate the actual operating conditions of the product and its sealing performance has become an urgent problem to be solved.

[0004] Currently, although rubber gaskets are widely used in the market, the lack of suitable testing equipment makes it impossible to conduct sealing tests on many products, or the test conditions differ significantly from actual usage conditions. This not only affects product performance verification but also poses challenges to product quality control. Therefore, developing a testing device that can simulate actual usage conditions and accurately evaluate the sealing performance of rubber gaskets is of great significance for improving product quality and ensuring safe use.

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0022] A rubber gasket sealing performance testing device includes a lower plate 1, an upper plate 2, and an adapter 3. The lower plate 1 is a cylinder, and its upper surface is provided with a product placement groove 1-1 that is concentrically arranged and matches the product shape. The upper end of the lower plate 1 is fixedly connected to the upper plate 2 by screws. Specifically, multiple corresponding screw holes are evenly distributed along the circumference of the outer edge of the upper surface of the lower plate 1 and the outer edge of the upper surface of the upper plate 2, and screws are installed in the corresponding screw holes. When oil medium is added to the product placement groove 1-1, the screw fixing can prevent the testing device from cracking. The outer side wall of the lower plate 1 is provided with two stepped threaded holes 1-4, which are correspondingly inserted into two adapters 3. Each adapter 3 extends into the product placement groove 1-1 and is used to connect the test medium.

[0023] The upper surface of the lower plate 1 is provided with two positioning holes 1-2. The two positioning holes 1-2 are located on the same diameter of the lower plate 1 and are symmetrically arranged on both sides of the center of the lower plate 1 for positioning the rubber pad.

[0024] The lower surface of the upper plate 2 is provided with two simulated part holes 2-2, and the two simulated part holes 2-2 are set in a one-to-one correspondence with the two positioning holes 1-2.

[0025] The upper surface of the lower plate 1 is provided with two mold-removing openings 1-5. The two mold-removing openings 1-5 are located on the same diameter of the lower plate 1, and two positioning holes 1-2 are symmetrically arranged on both sides of the center of the lower plate 1. Each mold-removing opening 1-5 is 30mm wide, 40mm long, and 5mm deep. The mold-removing openings 1-5 facilitate the disassembly of the tooling.

[0026] The upper plate 2 is symmetrically equipped with L-shaped handles 4 on both sides of its upper end, making it easy to pick up the upper plate 2.

[0027] The lower surface of the upper plate 2 and the upper surface of the lower plate 1 are provided with a plurality of corresponding pin slots. A pin 5 is inserted into each pair of corresponding pin slots to achieve initial guidance and positioning of the upper plate 2 and the lower plate 1.

[0028] This utility model is used in conjunction with a pressure testing machine. A rubber gasket is placed in the product placement groove 1-1, and the matching parts for the rubber gasket are inserted into the corresponding simulated part holes 2-2 and positioning holes 1-2. Then, the upper plate 2 is installed to form a closed space. Depending on the medium used in the product, one adapter 3 is the oil inlet and the other adapter 3 is the oil outlet, creating a pressure difference. At the same time, the utility model can be heated with the help of the test chamber to simulate the product's usage state. The sealing performance of the rubber gasket is judged by observing whether there is oil leakage between the upper plate 2 and the lower plate 1. This achieves a sealing test with pressure, medium, and temperature, and provides corresponding parameters according to the usage conditions.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of the equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
