Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and more specifically, to a pressure sealing device for the foaming test stage of foamed materials. Background Technology

[0002] Foamed materials are a class of materials with a unique honeycomb or porous structure. Their core is a composite material formed by introducing numerous pores into a matrix material such as polymers, metals, ceramics, or glass. Foamed materials require foaming tests to assess their performance, physical properties, and chemical stability. A conventional test involves filling a mold with a slurry of the foamed material and allowing it to foam. However, the slurry tends to bulge out after foaming within the mold, necessitating pressure sealing to prevent this bulging.

[0003] Pressure sealing is usually performed by pressing a pressure plate onto the mold, but there may be impurities or residual material splashed out during slurry filling on the mold surface, which will cause the mold to become less flat when in contact with the pressure plate. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a pressurization and sealing device for the foaming test stage of foamed materials. This device uses a scraper and a cleaning component to clean the mold and pressure plate before pressurization, thereby improving the flatness of the mold and pressure plate when they come into contact.

[0005] This utility model is achieved through the following technical solution: a pressure sealing device for the foaming test stage of foamed material, including a holding seat, the holding seat is used to place the mold, a bracket is fixedly connected to the holding seat, a crossbeam is fixedly connected to the top of the bracket, a first driving member is provided on the crossbeam, a pressure plate is fixedly connected to the output shaft of the first driving member, and the first driving member is used to drive the pressure plate to move towards the holding seat. The container is provided with several rail grooves, which are located on both sides of the mold. Each rail groove is slidably connected to a scraper, which is equipped with a scraper blade. The two ends of the scraper blade are fixedly connected to the scraper on both sides of the mold, and the bottom of the scraper blade abuts against the top of the mold. A second driving component is provided in the rail groove to drive the scraper to move. A cleaning component is provided on the top of the scraper, which is used to clean the bottom of the pressure plate when the scraper is moved by the second drive component.

[0006] Furthermore, the holding base is provided with a slot that engages with the mold.

[0007] Furthermore, several airbags are embedded in the inner wall of the slot, and an air pump is installed on the holding seat. All airbags are connected to the air pump.

Each cleaning unit includes a cylinder, with a rod slidably connected inside the cylinder. The rod extends beyond the top of the cylinder, and a cleaning head is detachably connected to one end of the rod extending outside the cylinder. An elastic element is provided inside the cylinder, and the elastic element abuts against the rod.

[0010] Furthermore, a contact plate is detachably connected to the bottom of the pressure plate.

[0017] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] The following detailed description illustrates the specific implementation method: Example 1: As attached Figures 1-5 As shown: A pressurized sealing device for the foaming test stage of foamed material includes a holding seat 1 for placing a mold, a bracket 2 bolted to the holding seat 1, a crossbeam 3 screwed to the top of the bracket 2, a first driving member 4 mounted on the crossbeam 3, a pressure plate 5 bolted to the output shaft of the first driving member 4, and the first driving member 4 for driving the pressure plate 5 to move toward the holding seat 1.

[0021] The holding base 1 has several rail grooves 6, located on both sides of the mold. Scraper frames 8 are slidably connected to each rail groove 6, and scraper blades 7 are mounted on the scraper frames 8. The two ends of the scraper blades 7 are bonded and fixed to the scraper frames 8 on both sides of the mold, and the bottom of the scraper blades 7 abuts against the top of the mold. A second driving component is installed within the rail groove 6 to move the scraper frames 8. Both the first driving component 4 and the second driving component are hydraulic cylinders. The stroke of the second driving component can drive the scraper frame 8 outside the pressing range of the pressure plate 5, thereby preventing the scraper frame 8 from being damaged after the pressure plate 5 lowers under pressure.

[0022] A cleaning assembly 9 is provided at the top of the scraper blade 7. The cleaning assembly 9 is used to clean the bottom of the pressure plate 5 when the scraper frame 8 is moved by the second drive component. The cleaning assembly 9 includes several cleaning units 91, which are distributed along the length of the scraper blade 7. Each cleaning unit 91 includes a cylinder 911. A rod 912 is slidably connected inside the cylinder 911. The rod 912 extends beyond the top of the cylinder 911. A cleaning head 913, which is a brush head, is detachably connected to one end of the rod 912 extending outside the cylinder 911. An elastic element 914, which is a spring, is provided inside the cylinder 911. The elastic element 914 abuts against and is welded to the rod 912. A pressure sensor 915 is bolted inside the cylinder 911. The end of the elastic element 914 away from the rod 912 abuts against the pressure sensor 915. Indicator lights 916 are screwed to the outside of the cylinder 911.

[0023] The bottom of the pressure plate 5 is detachably connected to the contact plate 10 via bolts.

[0024] In use, foaming material slurry is added into the mold, and the mold with the filling completed is placed on the holding seat 1. The height of the pressure plate 5 is adjusted by the first drive component 4 so that the pressure plate 5 enters the cleaning range of the cleaning component 9. The second drive component is activated, which drives the scraper 8 to move. As the scraper 8 moves, it drives the scraper blade 7 to scrape the upper surface of the mold, thereby removing impurities or spilled slurry from the upper surface of the mold, making the upper surface of the mold smoother.

[0025] Furthermore, as the scraper 7 is moved, the cleaning component 9 also cleans the bottom of the pressure plate 5, thereby removing impurities or dust from the bottom of the pressure plate 5 and improving flatness when in contact with the mold. Improved flatness can reduce the gap when the pressure plate 5 is pressed with the mold, thereby reducing the probability of the foaming material slurry overflowing from the gap when it expands.

[0026] After cleaning, the first drive component 4 is moved toward the mold, causing the pressure plate 5 to press and hold the mold. After being pressed, the mold can effectively resist the mechanical force generated by the expansion of the foaming material slurry through the pressure plate 5, thereby preventing the foaming material slurry from overflowing from the mold and ensuring the foaming effect.

[0027] As the number of pressurization cycles increases, the pressure plate 5 may undergo fatigue deformation due to long-term pressure, resulting in indentation at the contact area between the pressure plate 5 and the mold. Therefore, a contact plate 10 is detachably connected to the bottom of the pressure plate 5 by bolts. The contact plate 10 provides a contact surface with the mold. When the contact plate 10 deforms, it can be disassembled and replaced by bolts, thereby eliminating the indentation on the contact surface and maintaining the flatness of the contact.

[0028] The cleaning unit 91 consists of a rod 912 and an elastic element 914 inside the cylinder 911. The elastic element 914 is elastic and can adapt to certain dimensions. The cleaning head 913 is detachably connected to the rod 912 and can be replaced when it ages. It can also be replaced with a scraper head, mop head, etc., depending on the type of impurities and stains. In addition, a pressure sensor 915 is installed inside the cylinder 911. The pressure sensor 915 can detect the elastic force generated by the elastic element 914. When the bottom of the contact plate 10 is flat, theoretically, the pressure value detected by each cleaning unit 91 is equal. When the pressure value of a certain cleaning unit 91 is different from that of other cleaning units 91, if the pressure value is relatively increased, it indicates that there are larger stains or impurities. If the pressure value is relatively decreased, it indicates that the cleaning head 913 of that cleaning unit 91 has aged and deformed, or that the bottom of the contact plate 10 is dented, requiring replacement of the cleaning head 913 or the contact plate 10. An indicator light 916 on the outside of the cylinder 911 illuminates when the pressure value decreases, reminding the user to replace it in time.

[0029] Example 2: The difference from the above embodiment is that: a slot 11 is provided on the holding base 1, and the slot 11 engages with the mold. Several airbags 12 are embedded in the inner wall of the slot 11, and an air pump 13 is bolted to the holding base 1. All airbags 12 are connected to the air pump 13. A baffle 14 is provided at the top of the slot 11, and the baffle 14 is distributed along the edge of the slot 11. A switch 15 is provided on the holding base 1 to control the first driving component 4, the second driving component, and the airbags 12.

[0030] When placing the mold on the holding base 1, the user places the mold into the slot 11, which can limit and constrain the mold to prevent it from moving. The user can turn on the air pump 13 through the switch 15, which will inject air into the air bag 12, causing the air bag 12 to expand and clamp the mold, reducing the probability of mold displacement.

[0031] The guardrail 14 can block stains, impurities or splashed foam material slurry on the holding seat 1, reducing the probability of stains, impurities or splashed foam material slurry falling into the slot 11, thereby reducing the probability that the mold cannot be placed flat due to stains, impurities or splashed foam material slurry falling into the slot 11.

[0032] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
