Description

Technical Field

[0001] This application belongs to the field of sample making mold technology, and in particular relates to an adhesive sample making compression and exhaust device. Background Technology

[0002] Currently, in both laboratory and industrial production, traditional molds are commonly used to prepare silicone adhesive samples. The standard procedure involves injecting liquid or semi-liquid adhesive into the mold cavity, relying on the adhesive's own fluidity for initial leveling, or supplemented by simple manual smoothing, before directly placing the sample into an oven for heat curing. However, this traditional sample preparation method has several significant technical drawbacks:

[0003] 1. Poor surface quality of the sample: It is difficult to eliminate surface ripples by relying solely on the flow of the adhesive itself, and the low precision and uneven force of manual scraping can easily lead to uneven surface, scratches, or missing material at the edges of the final cured sample.

[0004] 2. Difficulty in removing internal air bubbles: During the adhesive injection process, air bubbles are inevitably drawn in. Traditional methods lack effective venting methods, and these bubbles are trapped inside the mold cavity, forming cavities or surface pits inside the sample after curing.

[0005] 3. Low sample preparation efficiency and long cycle: The above problems often result in a low first-time sample pass rate, requiring repeated preparation to obtain a sample that meets the test requirements. This may include injection, attempted venting, curing, finding non-compliance, and restarting. The entire process is cumbersome and highly dependent on the operator's experience, which seriously delays the overall test progress and fails to meet the efficiency requirements of modern quality control.

[0010] In this application, the central region of the top plate 112 of the portal frame is provided with a through hole for the elastic pressure mechanism 130 to pass through.

[0011] In this application, the elastic pressure mechanism 130 further includes a guide post 132 and a guide sleeve 133;

[0012] One end of the guide post 132 is fixedly connected to the cover plate 120, and the other end passes through the through holes on the elastic member 131 and the top plate 112 of the portal frame in sequence and is connected to the gripping part 140; the guide sleeve 133 is disposed in the through hole of the top plate 112 of the portal frame and slides in cooperation with the guide post 132.

[0013] The elastic element 131 is sleeved on the guide post 132 and is located between the cover plate 120 and the top plate 112 of the portal frame.

[0014] In this application, the inner wall of the side plate 111 of the portal frame is provided with a first slide rail 1111; the corresponding sides of the cover plate 120 are provided with first sliders 121 that cooperate with the first slide rail 1111.

The portal frame 110 provides a rigid, vertical guide path for the cover plate 120, ensuring that the cover plate 120 maintains vertical movement under the drive of the elastic pressure mechanism 130, fundamentally avoiding uneven sample thickness or uneven edge defects caused by pressure deviation. Simultaneously, the continuous, automatic pressure provided by the elastic pressure mechanism 130 thoroughly squeezes out air bubbles inside the adhesive and compacts and smooths the surface, ensuring that the final cured sample is dense, bubble-free, and has a smooth surface, greatly improving the quality of the test sample and the accuracy of the test results. Furthermore, since the compression device 100 itself is a stable integral structure, after compression and degassing are completed, it can be transferred as a whole, directly into the oven for curing along with the mold below.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0033] Example 1:

[0034] As attached Figure 1 As shown, in order to solve the above-mentioned technical problems, this application provides an adhesive sample preparation compression and degassing device, mainly comprising:

[0035] Compression device 100; the compression device 100 includes a portal frame 110, a cover plate 120 disposed on the inner wall of the side plate 111 of the portal frame, and an elastic pressure mechanism 130; the side plates 111 of the portal frame are disposed in the same direction and perpendicularly on opposite sides of the top plate 112 of the portal frame; the bottom end of the elastic pressure mechanism 130 is connected to the upper surface of the cover plate 120, and its top passes through the central region of the top plate 112 of the portal frame; wherein, the elastic pressure mechanism 130 includes at least one elastic element 131; the cover plate 120 can slide axially on the inner wall of the side plate 111 of the portal frame by the drive of the elastic pressure mechanism 130.

[0036] It should be noted that the core of this application embodiment lies in the compression device 100 that can transmit the pressure of the gas in the sample pack. In this embodiment, the portal frame 110 serves as a rigid support and guide foundation and is composed of a top plate 112 and a pair of side plates 111.

[0037] Preferably, the portal frame 110 can be integrally formed by cutting and bending a 10mm thick 304 stainless steel plate to ensure its structural stability and prevent deformation under pressure and heat. The top plate 112 is a rectangular plate of 200mm × 150mm. A pair of side plates 111 are perpendicular to the top plate 112. The dimensions of the side plates 111 can be 150mm × 80mm, and they are arranged parallel to each other on opposite sides of the long side of the top plate 112, thus forming a stable "portal" shaped structure. The above dimensional data are only a preferred reference and are not limited thereto. This structure provides a reliable reference for the entire compression process, ensuring that the applied pressure is a purely vertical downward force, avoiding uneven pressure caused by frame deformation or tilting.

[0038] It should be noted that in this embodiment, the cover plate 120 is used to directly transmit pressure and achieve surface flatness.

[0039] Preferably, the cover plate 120 can be a hard anodized aluminum alloy plate with a thickness of 8mm and a planar dimension of 180mm × 130mm, slightly smaller than the inner contour of the portal frame 110, so that it can be accommodated between the two side plates 111. Its lower surface is finely ground, with extremely high flatness and smoothness. The high flatness of the surface ensures perfect fit with the sample mold plate 200, making it easy to obtain a flat sample surface.

[0040] In this embodiment, the elastic pressure mechanism 130 is used to provide and transmit continuous, uniform compressive force. (See attached diagram) Figure 2 The diagram shown is a structural schematic of the elastic pressure mechanism in one embodiment of the application.

[0041] Preferably, this embodiment uses two parallel stainless steel helical compression springs as elastic elements 131. Their wire diameter is 2mm, outer diameter is 20mm, and free height is 80mm. The stainless steel material can withstand the high temperatures of the oven; the two springs in parallel provide an initial preload of approximately 100N, ensuring sufficient force for venting and compaction, while the pressure is gentle and will not damage the mold.

[0042] The guide post 132 can be two 12mm diameter hard chrome steel optical shafts, whose lower ends are securely connected to the upper surface of the cover plate 120 via threads. The guide sleeve 133 can be a self-lubricating copper sleeve embedded in the through hole of the top plate 112, with its inner diameter precisely sliding with that of the guide post 132. In this embodiment, the cooperation between the guide post 132 and the guide sleeve 133 ensures that the cover plate 120 slides up and down smoothly without any shaking, strictly limiting its movement path to only the vertical axis, achieving uniform pressure and preventing the cover plate from jamming.

[0043] In this application, the compression device 100 further includes a gripping part 140; the gripping part 140 is connected to the top end of the elastic pressure mechanism 130.

[0044] It should be noted that, to facilitate user operation of the elastic pressure mechanism 130, the elastic pressure mechanism 130 in this embodiment may further include a gripping portion 140. Preferably, as shown in the attached... Figure 2 As shown, the grip 140 can be a T-shaped handle, which is connected to the upper end of the guide post 132 passing through the top plate 112 via a thread. The T-shaped design is ergonomic, making it easy for users to apply force with both hands or one hand to perform downward and upward operations.

[0045] In this application, to ensure the stability of the sliding of the cover plate 120, this embodiment provides two preferred sliding fit schemes:

[0046] As attached Figure 3 The diagram shown is a structural schematic of the slide rail and slider in one embodiment of this application. A standard linear slide rail 1111 is fixed to the inner wall of the side plate 111 of the portal frame by screws, and sliders 121 that precisely mate with the linear slide rail 1111 are installed on the corresponding sides of the cover plate 120. This design uses a standard linear guide pair, resulting in high guiding accuracy, low friction coefficient, extremely smooth movement, and long service life.

[0047] Alternatively, raised slide rails 122 can be machined on the corresponding sides of the cover plate 120. A groove matching the slide rail 122 can be opened on the inner wall of the side plate 111 of the portal frame, and a second slider 1112 can be embedded in the groove. This solution has a more compact structure, stronger overall integrity, and can effectively reduce the size and weight of the device.

[0048] As attached Figure 4 As shown in the schematic diagram of the sample mold plate in one embodiment of this application, in this application, the adhesive sample preparation compression and exhaust device further includes:

[0049] Sample mold plate 200; demolding grooves 210 are provided at one or both opposite edges of the sample mold plate 200;

[0050] The cover plate 120 is detachably disposed on the upper surface of the sample mold plate 200, and the lower surface of the cover plate 120 is in contact with the upper surface of the sample mold plate 200; the pressure provided by the elastic pressure mechanism 130 is directly transmitted to the sample mold plate 200 through the cover plate 120.

[0051] It should be noted that the target mold in this embodiment serves as the basis for sample preparation, on which specific sample cavity is machined to contain liquid adhesive and determine the final shape of the sample; the sample mold plate 200 serves as a precision top cover plate for the target mold. Its lower surface is used to cover the cavity opening of the target mold, closing the open cavity and forming a sealed molding space with its top surface sealed by the sample mold plate 200.

[0052] In this application, the lower surface of the sample mold plate 200 is used to cover the target mold of the sample cavity; the outline of the sample mold plate 200 is adapted to the opening outline of the target mold, and the area of ​​the sample mold plate 200 is not less than the opening area of ​​the target mold.

[0053] Preferably, the sample mold plate 200 can be a transparent polycarbonate plate with a thickness of 8mm, whose outline is precisely matched with the opening outline of the target mold, and whose area is slightly larger than the opening area to ensure that it can completely cover and seal the cavity. However, it is not limited to this.

[0054] In this application, a groove door 220 is hinged to the demolding groove 210; when the groove door 220 is closed, it covers the demolding groove 210 and is flush with the surface of the sample mold plate 200.

[0055] Preferably, as shown in the appendix Figure 5 As shown in the top view of another sample mold plate in one embodiment of this application, in this preferred embodiment, demolding grooves 210, 2mm deep and 5mm wide, are machined on the opposite sides of the sample mold plate 200. Each groove is hinged with a groove door 220 via a micro-hing. During molding, the groove door 220 is closed and flush with the plate surface to ensure the integrity of the pressure surface; during demolding, the groove door 220 is pried open, and tools can be inserted into the groove to pry and easily separate the mold plate that may be adhered to the sample.

[0056] The working principle and process of the compression exhaust device in this embodiment are as follows:

[0057] First, the liquid adhesive is filled into the sample cavity of the target mold. Then, the sample mold plate 200 is placed over the cavity opening of the target mold, ensuring that the recessed door 220 is closed. Next, the cover plate 120 of the compression device 100 is aligned and placed on the upper surface of the sample mold plate 200. The user presses down on the grip 140, and the elastic pressure mechanism 130 drives the cover plate 120 to apply pressure to the sample mold plate 200. This pressure is transmitted to the adhesive through the sample mold plate 200, squeezing out air bubbles and ensuring that the adhesive surface is completely adhered to the lower surface of the sample mold plate 200, thereby ensuring the flatness of the top surface of the sample.

[0058] While maintaining compression, the assembly of the compression device 100, the sample mold plate 200, and the target mold 300 is placed together in an oven for heating and curing. The continuous pressure provided by the spring is crucial in the early stages of curing.

[0059] After curing, remove the whole piece, lift the gripping part 140 upwards to release the compression device 100, then use the demolding groove 210 to pry open the sample mold plate 200, and finally take out the formed sample from the target mold.

[0060] In summary, this embodiment, through the implementation of the above-described specific structure, achieves the invention's objective of providing uniform pressure, ensuring vertical guidance, facilitating overall operation and curing, and effectively prepares a high-quality test sample with a smooth surface and no internal bubbles.

[0061] In this application, the central region of the top plate 112 of the portal frame is provided with a through hole through which the elastic pressure mechanism 130 passes.

[0062] It should be noted that, in this embodiment, a through hole for the elastic pressure mechanism 130 to pass through is precisely machined in the central region of the top plate 112 of the portal frame. The axis of the through hole is perpendicular to the plane of the top plate 112, and its position is aligned with the center of the cover plate 120 below.

[0063] Preferably, the diameter of the through hole is machined to a tolerance grade of Φ14H7 to ensure an interference fit with the subsequent guide sleeve 133.

[0064] In this application, the elastic pressure mechanism 130 further includes a guide post 132 and a guide sleeve 133; one end of the guide post 132 is fixedly connected to the cover plate 120, and the other end passes through the elastic member 131 and the through holes on the top plate 112 of the portal frame in sequence and is connected to the gripping part 140; the guide sleeve 133 is disposed in the through hole of the top plate 112 of the portal frame and slides in cooperation with the guide post 132; the elastic member 131 is sleeved on the guide post 132 and is located between the cover plate 120 and the top plate 112 of the portal frame.

[0065] It should be noted that in this embodiment, the guide post 132 consists of two hard chrome steel optical shafts with a diameter of 12mm and a tolerance of f7, the lower ends of which are firmly connected to the upper surface of the cover plate 120 by threads; the guide sleeve 133 is a standard self-lubricating copper sleeve, the outer diameter of which is interference-fitted with the Φ14H7 through hole on the top plate 112 and is pressed into the through hole for fixation; the inner diameter of which is precision sliding fit with the guide post 132 of G6 / h5.

[0066] In this embodiment, the guide sleeve 133 is fixed in the through hole of the top plate 112, providing a smooth, wear-resistant, and precise guiding channel for the guide post 132. This structure ensures that the guide post 132 slides up and down smoothly without radial wobble, strictly limiting its movement path to only the vertical axis. This is the core guarantee for achieving uniform pressure on the cover plate 120 and avoiding skewing and jamming, while also protecting the through hole on the top plate 112 from wear and extending the service life of the device.

[0067] In this embodiment, two parallel stainless steel helical compression springs are used as elastic elements 131. They are sleeved on the outside of the guide post 132 and located between the cover plate 120 and the top plate 112 of the portal frame. The guide post 132 passes through the center of the spring and also serves to prevent the spring from buckling and bending.

[0068] In this application, the inner wall of the side plate 111 of the portal frame is provided with a first slide rail 1111; the corresponding sides of the cover plate 120 are provided with first sliders 121 that cooperate with the first slide rail 1111.

[0069] In this application, the cover plate 120 is provided with second slide rails 122 on both sides; the inner wall of the side plate 111 of the portal frame is provided with a second slider 1112 that cooperates with the second slide rails 122.

[0070] It should be noted that in this embodiment, the slide rail can be set on the side plate 111, and the slider can be set on the cover plate 120; or the slide rail can be set on the cover plate 120, and the slider can be set on the side plate 111.

[0071] Preferably, the first slide rail 1111 can be selected from the guide rail portion of a standard miniature ball linear slide rail assembly available on the market, with a cross-sectional width of 9mm and a length of 140mm, and is vertically fixed to the inner wall of the side plate 111 by four M4 hex socket screws; while the first slider 121 is a ball slider that matches the above-mentioned guide rail. The first sliders 121 on both sides of the cover plate are mounted on the side of the cover plate 120 by two M4 screws. The slider may contain a ball circulation channel to achieve high-precision, low-resistance linear motion, and is not limited to this.

[0072] It should be noted that when installing the two first slide rails 1111, precision measuring tools must be used to ensure that they are strictly parallel and perpendicular to the plane of the top plate 112 of the portal frame 110.

[0073] This embodiment employs a professional linear guide pair, which greatly reduces the coefficient of friction, making the up-and-down sliding of the cover plate 120 extremely smooth and stable, without any jamming or shaking. This ensures the absolute perpendicularity of the pressure transmission direction.

[0074] In this application, the area of ​​the cover plate 120 is not less than the area of ​​the sample mold plate 200.

[0075] Preferably, in this embodiment, the sample mold plate 200 can be a rectangular plate covering the corresponding adhesive sample mold, with dimensions of 150mm × 100mm. Correspondingly, the cover plate 120 is designed as a rectangular plate of 160mm × 110mm, with an area slightly larger than the sample mold plate 200, ensuring that the outline of the cover plate 120 completely encloses the outline of the sample mold plate 200 during placement. This structural design ensures that the pressure generated by the elastic pressure mechanism 130 completely and evenly covers and acts on the entire sample forming area, avoiding edge pressure loss or pressure gradients.

[0076] In this application, two connecting rods 1113 are also arranged in parallel between the two inner walls at the bottom of the side plate 111 of the portal frame; the height distance between the connecting rods 1113 and the lower surface of the cover plate 120 is greater than the total height of the target mold on which the sample mold plate 200 is covered.

[0077] As attached Figure 6 The diagram shown is a structural schematic of another adhesive sample preparation compression and venting device according to an embodiment of this application. It should be noted that in this embodiment, two connecting rods 1113 can be arranged parallel to each other between the bottom inner walls of the side plates 111 of the portal frame. The height distance between these two connecting rods 1113 and the cover plate 120 is slightly greater than the height of the target mold after the sample mold plate 200 is closed, facilitating insertion, removal, and compression operations. Before starting the compression operation, the two ends of the target mold are placed correspondingly on these two connecting rods 1113. During the compression operation, the cover plate 120 transmits downward pressure to the sample mold plate 200 and the target mold, while the connecting rods 1113 provide support and apply an upward force to the target mold, making the compression and sustained effect more effective.

[0078] In summary, this application embodiment constructs a compression device 100 integrating a rigid portal frame 110, a cover plate 120 that can slide precisely along the frame, and an elastic pressure mechanism 130 that passes through the top plate 112. This device works in conjunction with a sample mold plate 200, which serves as a precision cover plate and has a demolding groove 210, to achieve efficient, one-time compression, degassing, and leveling of the adhesive inside the target mold 300, greatly improving sample preparation efficiency and effectiveness.
