[0044] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0045] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0047] See also Figure 1-Figure 3 As shown, according to the technical solution of the present invention, the apparatus for curing and molding a block-shaped absorbing material includes a first mold and a second mold, which are arranged horizontally in sequence. The first mold includes a first mold cavity layer 1, one side of which is provided with a first molding cavity 11 and a first injection port 12 that are interconnected. The first injection port 12 is located at the bottom of the first mold cavity layer 1. During use, the first mold is arranged vertically, that is, perpendicular to the ground, a horizontal surface, or the plane of the equipment base.

[0048] Similarly, the second mold includes a second mold cavity layer 2. The second mold cavity layer 2 is provided with a second molding cavity 21 and a second injection port 22 that are interconnected on the side facing the first mold cavity layer 1. The second injection port 22 is provided at the bottom of the second mold cavity layer 2. When in use, the second mold is arranged in a vertical direction, that is, perpendicular to the ground, a horizontal plane, or the plane of the equipment base.

[0049] Specifically, the first molding cavity 21 and the second molding cavity 22 are arranged in correspondence with each other. During use, the first mold cavity layer 1 and the second mold cavity layer 2 are affixed to each other, and the first molding cavity 21 and the second molding cavity 22 are combined to form the molding cavity of the mold. The injected injection molding material is solidified and formed into a block-shaped absorbing material in this molding cavity. Among them, the first molding cavity 21 and the second molding cavity 22 can be designed into different shapes according to actual needs, with circular or square shapes being common. The first injection port 12 and the second injection port 22 are arranged in correspondence with each other, and the two are combined to form the injection port of the mold. The external injection molding device injects the flowing material into the interior of the mold through the injection port, and finally injects it into the molding cavity to complete the solidification molding.

[0050] See also Figure 2 and Figure 3 As shown, both the first injection port 12 and the second injection port 22 are configured in a Y-shaped structure. The Y-shaped structure specifically includes a first port connected to an external injection device, the first port bifurcating upward to form two second ports, and the second ports communicating with a mold cavity layer formed by the combination of the first mold cavity layer 1 and the second mold cavity layer 2. During injection molding, the injection device injects material into the first port, which then flows into the mold cavity layer separately through the two second ports.

[0051] In the technical solution of this embodiment, the first and second molds of the block-shaped absorbing material curing and molding apparatus are designed in a left-right layout, that is, the first cavity layer 1 and the second cavity layer 2 are arranged left and right. Since the injection port is located at the bottom of both cavity layers, the injection material is injected upward from below the injection port. Compared with the traditional top-down mold layout and horizontal injection arrangement, the bottom-up injection process of the present invention can leverage the material's own gravity, thereby effectively reducing the probability of bubble formation, ultimately improving the quality of the block-shaped absorbing material obtained after demolding the curing and molding apparatus. Furthermore, the Y-shaped structure of the bottom injection port significantly accelerates the injection speed during material injection. At the same time, the Y-shaped structure provides the necessary buffer area for injection. Compared with the traditional single, straight injection port design, the curing and molding apparatus of the present invention can improve the stability and continuity of the injection process.

[0052] See also Figure 2 and Figure 3 As shown, in a preferred embodiment of this embodiment, the first injection port 12 is recessed inward to form a first buffer groove 13, and / or the second injection port 22 is recessed inward to form a second buffer groove 23. Specifically, when the first cavity layer 1 and the second cavity layer 2 are in contact with each other, the first buffer groove 13 and the second buffer groove 23 can both be used to provide a buffering effect for the injection of the injection material, increase the material buffer area of ​​the injection port, and prevent the injection of unstable or discontinuous materials caused by injection pressure. Compared with the traditional single straight injection port design, the buffer groove design can improve the stability and continuity of the injection process. In particular, when the first buffer groove 13 and the second buffer groove 23 are provided at the same time, the two buffer grooves are combined to form a buffer cavity, further increasing the buffer area.

[0053] Example 1

[0054] In the first embodiment of the present utility model, a technical solution is provided regarding the specific structural design of the vacuum assembly and the assembly relationship between the vacuum assembly and the mold cavity layer.

[0055] See also Figure 2 and Figure 3 As shown, in the technical solution of this embodiment, the block-shaped absorbing material curing and molding device also includes an exhaust assembly. Exhaust ports 9 are provided at the tops of both the first mold cavity layer 1 and the second mold cavity layer 2. One end of the exhaust port 9 communicates with the molding cavity formed by the combination of the first molding cavity 11 and the second molding cavity 21 via a mold cavity exhaust channel 14, and the other end communicates with the exhaust assembly. Specifically, the molding cavity formed by the combination of the first molding cavity 11 and the second molding cavity 21 is connected to the external exhaust assembly via the mold cavity exhaust channel 14 and the exhaust port 9. The exhaust action of the exhaust assembly generates a pressure differential, which pushes the less fluid material toward the interior of the mold cavity layer, further accelerating the injection speed, while also facilitating the exhaust of gas within the mold cavity layer and improving the quality of the finished product.

[0056] See also Figure 1 and Figure 2 As shown, in a preferred embodiment of the present invention, the air extraction assembly includes an air extraction device (not shown in the figure), a buffer 7 and a pipe 8. One end of the buffer 7 is connected to the air extraction device through the pipe 8, and the other end is detachably connected to the exhaust port 9. The air extraction device can be a device that can generate a gas suction effect, such as an air pump. When started, a pressure difference is generated, so that the material flowing out of the injection molding device pipe can smoothly pass through the injection port formed by the combination of the first injection port 12 and the second injection port 22 under the action of the thrust and enter the molding cavity formed by the combination of the first molding cavity 11 and the second molding cavity 21, while also helping to discharge the gas in the two mold cavity layers.

[0057] See also Figure 2 and Figure 3 As shown, in an optional scheme, a scheme for the connection between the vacuum assembly and the cavity layer is provided. Among them, the exhaust port 9 is set as a threaded hole, and the bottom of the buffer 7 is provided with a threaded connection end 71, and the threaded connection end 71 is screwed into the threaded hole, thereby achieving the effect of detachable connection between the buffer 7 and the cavity layer. When the molding and curing device is used to cure and process some materials with good fluidity, the vacuum assembly can be omitted, and the material is injected into the cavity layer through the pressurization of the external injection molding device (pressurization of the injection molding pipe port); when the molding and curing device is used to cure and process some materials with poor fluidity, the vacuum assembly can be equipped, and the threaded connection end 71 at the bottom of the buffer 7 is screwed into the threaded hole to achieve connection, and the vacuum action of the vacuum device generates a pressure difference, which pushes the material with poor fluidity to flow toward the cavity layer, thereby accelerating the injection speed.

[0060] See also Figure 2 As shown, in the technical solution of this embodiment, the first mold cavity layer 1 is provided with a first mold exhaust channel 15 that is not connected to the first molding cavity 11 or the second molding cavity 21. The first mold exhaust channel 15 is connected to the exhaust port 9. The first mold exhaust channel 15 is used to promptly exhaust air or other gases between the first mold cavity layer 1 and the second mold cavity layer 2, thereby avoiding molding defects and ensuring the molding quality and dimensional stability of the block-shaped absorbing material. Furthermore, when an exhaust assembly is installed, gas exhaust can be further accelerated, improving molding quality.

[0061] Optionally, the number of the first mold exhaust channels 15 can be set to two, and the tops of the two channels are both connected to the exhaust port 9.

[0062] See also Figure 2 As shown, in a preferred embodiment of this embodiment, the first mold cavity layer 1 is further provided with a second mold venting channel 16 that is not connected to the first molding cavity 11 or the second molding cavity 21. The second mold venting channel 16 has openings at the top and bottom of the first mold cavity layer 1, respectively. These two openings constitute the two exhaust ports of the second mold venting channel 16. The second mold venting channel 16 is used to promptly exhaust air or other gases between the first mold cavity layer 1 and the second mold cavity layer 2 during lamination, thereby avoiding molding defects. Combined with the first mold venting channel 15, the molding quality and dimensional stability of the block-shaped absorbing material can be further improved.

[0063] Optionally, the number of the second mold exhaust channels 16 can be set to two, and the two channels are symmetrically arranged on both sides of the first molding cavity 11.

[0064] Example 3

Specifically, the mold positioning post 17 is used to be inserted into the mold positioning hole 24 when the first mold cavity layer 1 and the second mold cavity layer 2 are closed, thereby playing a role in matching and positioning, improving the mold positioning accuracy, ensuring the mold's position is fixed, and ensuring the stability and accuracy of the mold during the processing process, avoiding the reduction of processing accuracy due to changes in the mold position, and ensuring that the quality and shape of the molded product meet the design requirements.

[0067] Optionally, the number of the model positioning columns 17 and the number of the model positioning holes 24 are equal, and preferably four, which are respectively arranged at the four corners of the first mold cavity layer 1 and the second mold cavity layer 2 .

The mold cavity positioning column 25 is used to be inserted into the mold cavity positioning groove 18 when the first mold cavity layer 1 and the second mold cavity layer 2 are molded together. Thus, on the basis of the positioning function played by the mold positioning column 17 and the mold positioning hole 24, the mold cavity positioning column 25 further plays a precise positioning function for the corresponding position of the first molding cavity 11 and the second molding cavity 21, ensuring that the positions of the first molding cavity 11 and the second molding cavity 21 are completely corresponding, thereby forming a molding cavity for curing and molding the absorbing material, and ensuring that the quality and shape of the product molded in the molding cavity meet the design requirements.

[0069] Optionally, the number of the mold cavity positioning columns 25 and the mold cavity positioning grooves 18 are equal, and preferably there are two of them, which are respectively arranged above the first molding cavity 11 and the second molding cavity 21, and are respectively arranged adjacent to the two molding cavities.

[0070] Example 4

[0073] Optionally, threaded holes are provided on the first plywood fixing layer 4, the first connecting layer 3, and the first mold cavity layer 1, and the three are fixedly connected by any one of bolts, screws, or screws.

[0074] Example 5

[0075] In the fifth embodiment of the present invention, a process scheme for realizing injection molding and curing by using the block-shaped absorbing material curing and molding device described in embodiments 1-4 is provided.

[0076] 1) Prepare the mold: Prepare a mold with a molding cavity of the corresponding shape according to the shape and size of the required block absorbing material, ensure that the inside of the mold cavity layer is clean and free of impurities, and apply a release agent on the inner surface of the mold cavity layer.

[0077] 2) Install the mold: Install the two molds on the two clamping plates of the left and right molding press respectively, align the holes and then press them together tightly.

[0078] 3) Install the exhaust assembly: Install a detachable buffer above the exhaust hole in the cavity layer and connect the pipes and exhaust device. Of course, in this utility model, the exhaust assembly is a selectively installed component and is only used when decompression is required to assist injection molding of materials with poor fluidity.

[0079] 4) Injection and Curing: The external injection molding device is activated to inject the flowing material into the mold cavity through the Y-shaped injection port of the mold cavity layer. Simultaneously, the exhaust device is activated to create a pressure differential to promote material flow and expel air from the mold. Once the material fills the mold, the injection molding machine is turned off and the material is allowed to solidify.

[0080] 5) Demolding and inspection: After the material is completely solidified, open the molding press, take out the finished product, and conduct quality inspection.

[0081] In summary, the block absorbing material curing and molding device provided by the present invention adopts a left-right layout design, and the injection port is set at the bottom of the mold cavity layer. The injection material is injected upward from the bottom of the injection port. The injection process uses the gravity of the material itself to effectively reduce the probability of bubble generation, and ultimately improve the quality of the finished product obtained by demolding the curing and molding device. In addition, the present invention designs the injection port as a Y-shaped structure with a buffer groove. Since it is bifurcated into two channels and the buffer area at the injection port is increased, the injection speed can be significantly accelerated when injecting the material. At the same time, the Y-shaped structure can provide the necessary buffer area for the injection, thereby improving the stability and continuity during the injection process. In addition, by installing a detachable vacuum assembly above the exhaust hole, a pressure difference is generated by the vacuum action, which pushes the material with poor fluidity to flow toward the inside of the mold cavity layer, further accelerating the injection speed, and also helps to discharge the gas in the mold cavity layer, thereby improving the quality of the finished product.

[0082] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
