Detailed Implementation
[0026] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0027] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0028] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0029] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0030] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0031] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0032] Considering that existing high-pressure vessel molds used in cold isostatic pressing are generally fixed-size molds, these molds are only suitable for producing blanks of fixed sizes, resulting in low applicability. Furthermore, the molds must be cut and disassembled for recycling, making the process cumbersome. This application provides a combined cold isostatic pressing mold and forming apparatus, which is applicable to producing blanks of various fixed sizes, offering high applicability and a simpler recycling process.
[0033] Specifically, see Figure 1 and Figure 2As shown, this application provides a combined cold isostatic pressing mold 1, which may include plate 110, a first locking member 200, a cover 300, and a pressing assembly 400. The plate 110 is detachably assembled to form a receiving body 100 with an opening 100a, and adjacent plate 110s are each provided with a locking portion. The first locking member 200 is used to lock the locking portions of two adjacent plate 110s to fix the two adjacent plate 110s to each other. The cover 300 is detachably provided over the opening 100a. The pressing assembly 400 includes a pressing member 410 and at least two second locking members 420. The pressing member 410 presses against the side of the cover 300 away from the opening 100a. The second locking members 420 are respectively connected to different sides of the pressing member 410 along the circumference of the opening 100a. The second locking member 420 includes an adjusting member 421 and a first connecting member 422 and a second connecting member 423 disposed at both ends of the adjusting member 421. The first connecting member 422 is connected to the pressing member 410, and the second connecting member 423 is connected to the plate 110. The second locking member 420 can be adjusted by adjusting the adjusting member 421 so that the first connecting member 422 and the second connecting member 423 are pulled together, and the pressing member 410 applies pressure to the cover 300.
[0034] The aforementioned combined cold isostatic pressing mold 1 can be detachably assembled from plates 110 to form a container 100 with an opening 100a. This allows the cold isostatic pressing mold to be assembled from plates 110 of different sizes to form containers 100 of different volumes. Thus, the combined cold isostatic pressing mold 1 can be applied to scenarios where various fixed-size blanks are produced. It is worth noting that the combined cold isostatic pressing mold 1 of this application is also provided with a pressing component 400. The pressing component 400 is used to apply pressure to the cover 300 so that the cover 300 can be securely placed on the opening 100a. Moreover, the pressing component 400 can be applied to scenarios where various fixed-size blanks are produced, which helps to improve the applicability of the combined cold isostatic pressing mold 1. In addition, when recycling the combined cold isostatic pressing mold 1, only the first locking member 200 needs to be disassembled to disassemble the container 100 into separate plates 110. This facilitates recycling and avoids the trouble of cutting and disassembling the combined cold isostatic pressing mold 1, thus improving the ease of recycling the combined cold isostatic pressing mold 1.
[0035] It should be noted that the aforementioned second locking element 420 can be configured as two, three, or four, etc. For example, in conjunction with... Figure 1 As shown, there can be two second locking elements 420, which are symmetrically distributed on both sides of the housing 100, so that pressure can be applied evenly to the cover 300.
[0036] Understandably, when there are three or more second locking elements 420, the second locking elements 420 can be distributed at equal angles along the circumference of the opening 100a, which can ensure the balance of the pressure applied to the cover 300 and improve the stability of the cover 300.
[0037] For example, when there are four second locking elements 420, adjacent second locking elements 420 can be distributed at 90 degrees along the circumference of the opening 100a.
[0038] Optionally, the aforementioned pressing member 410 may be configured as a rod, pressure plate, or block, etc.
[0039] Optionally, combined Figure 1 As shown, the two ends of the adjusting member 421 can be respectively provided with a first threaded hole and a second threaded hole. The first connecting member 422 includes a first screw 4221 and a first connecting part 4222. The first screw 4221 passes through the first threaded hole, and the first connecting part 4222 is connected to the pressing member 410. The second connecting member 423 includes a second screw 4231 and a second connecting part 4232. The second screw 4231 passes through the second threaded hole, and the second connecting part 4232 is used to connect the plate 110. The adjusting member 421 is used to rotate relative to the first screw 4221 and the second screw 4231 so that the first screw 4221 and the second screw 4231 move closer to or further away from each other, thereby realizing the pressing or loosening effect of the pressing member 410 on the cover 300.
[0040] Specifically, the aforementioned first screw 4221 can be connected to the first threaded hole in a positive spiral, and the second screw 4231 can be connected to the second threaded hole in a negative spiral. This enables the first screw 4221 and the second screw 4231 to move closer to or further away from each other when the adjusting member 421 rotates forward or backward relative to the first screw 4221 and the second screw 4231.
[0041] Understandably, in some other embodiments, the adjusting member 421 can also be configured as a telescopic rod with a snap-fit structure at both ends. The first screw 4221 can be replaced with a snap-fit rod with a snap-fit groove spaced apart. Similarly, the second screw 4231 can also be replaced with a snap-fit rod with a snap-fit groove spaced apart. In this way, the snap-fit structure of the telescopic rod can be snapped into the snap-fit groove at different positions through the telescopic action of the telescopic rod, thereby realizing the pressing or loosening action of the pressing member 410 on the cover 300.
[0042] Optionally, the first connecting part 4222 can be configured as a connecting ring, and the pressing member 410 can be provided with a flange that can pass through the connecting ring. This enables the first connecting member 422 and the pressing member 410 to be detachably connected, improving the ease of pressing the cover 300.
[0043] It is worth noting that the aforementioned pressing member 410 can be configured as a pressure plate or block, etc., and adaptably, the aforementioned flange can be integrally formed on the side edge of the aforementioned plate or block.
[0044] Optionally, in some other embodiments, the first connecting portion 4222 is configured as a connecting ring, and the pressing member 410 is configured as a rod, the end of which can pass through the connecting ring. Specifically, in this embodiment, the second locking member 420 can be adaptively configured as two, and the first connecting portions 4222 of the two second locking members 420 can be used to sleeve on both ends of the rod, thereby achieving balanced pressing on the cover 300.
[0045] Combination Figure 1 and Figure 2 As shown, the plate 110 is provided with a first hook 111 and a second connecting part 4232 is configured as a hook. The hook is detachably hooked to the first hook 111, which enables the second connecting part 4232 to be detachably connected to the plate 110, thus improving the ease of pressing the cover 300 by the pressing assembly 400.
[0046] Optionally, see Figure 2 The plate 110 is provided with a second hook 112, which is used for crane lifting.
[0047] Specifically, after the combined cold isostatic pressing mold 1 completes the molding process, the crane can lift the combined cold isostatic pressing mold 1 by hooking the second hook 112. This makes the combined cold isostatic pressing mold 1 applicable to molding scenarios of large blanks, thus improving the applicability of the combined cold isostatic pressing mold 1.
[0048] Optionally, please continue reading Figure 2 The second hook 112 may include a first lifting ring 1121 and a second lifting ring 1122, which are spaced apart along the depth direction of the opening 100a.
[0049] Specifically, the aforementioned first lifting ring 1121 can be positioned near the opening 100a, and the second lifting ring 1122 can be positioned away from the opening 100a. Thus, the first lifting ring 1121 can be used by the crane to lift the combined cold isostatic pressing mold 1 away from the molding tank, and the second lifting ring 1122 can cooperate with the first lifting ring 1121 to allow the crane to lay the combined cold isostatic pressing mold 1 flat. Furthermore, the second lifting ring 1122 can be used by the crane for independent lifting; it should be noted that in this case, the first lifting ring 1121 is not lifted by the crane. This allows the combined cold isostatic pressing mold 1 to be further tilted and flipped so that the opening 100a faces downwards, thereby facilitating the unloading of the molded blank. Thus, the aforementioned arrangement of the first lifting ring 1121 and the second lifting ring 1122 facilitates the crane's various operations such as lifting or flipping, improving the ease of the crane's lifting process.
[0050] Preferably, the first lifting ring 1121 can be provided on both opposite sides of the container 100, so that the crane can lift from both sides of the container 100 at the same time, which can reduce the shaking of the combined cold isostatic pressing mold 1 when it is lifted by the crane and improve the stability of the lifting process.
[0051] Optionally, see Figure 2 and Figure 3 The housing 100 can be formed by splicing the edges of adjacent plates 110. The first locking member 200 includes an angle steel 210 and a locking nut 220. The angle steel 210 is provided with a third threaded hole, and the locking part is provided with a fourth threaded hole. The angle steel 210 is used to fit against the splice of two adjacent plates 110, so that the third threaded hole and the fourth threaded hole are aligned. The locking nut 220 is used to lock the third threaded hole and the fourth threaded hole, thus enabling quick assembly and disassembly between adjacent plates 110.
[0052] Optionally, see Figure 2 In some embodiments, the angle steel 210 may include at least two segments, which are spaced apart along the edge direction of the plate 110, thereby improving the ease of locking the angle steel 210.
[0053] Optionally, see Figure 3 In some other embodiments, the angle steel 210 can be set as a segment, and the third threaded holes are arranged at intervals along the extension direction of the angle steel 210. The angle steel 210 covers the edge of the plate 110 and the third thread is aligned with the fourth threaded hole, which can improve the strength of the angle steel 210 in connecting and fixing adjacent plates 110.
[0054] Optionally, combined Figure 2 and Figure 3As shown, the plate 110 has at least two liquid-permeable holes 113, which can be irregularly distributed on the plate 110 to allow for the flow of the medium and ensure that pressure can be transmitted to the powder or blank inside the mold. It should be noted that the aforementioned medium refers to the pressure-transmitting medium such as liquid or gas used in the cold isostatic pressing process, which is used to uniformly pressurize the powder or granular material.
[0055] Preferably, the liquid penetration holes 113 are arranged in a regular pattern on the plate 110, such as a square arrangement or a triangular arrangement.
[0056] Optionally, the liquid penetration holes 113 are distributed in a matrix on the plate 110, which ensures that the pressure of the medium can be evenly transmitted to the powder or blank inside the mold, thereby improving the molding effect.
[0057] This application also provides a molding apparatus, including the aforementioned combined cold isostatic pressing mold 1. The molding apparatus further includes a rubber sleeve for being fitted into the container 100. Specifically, the rubber sleeve is used to fill the powder or blank to be molded.
[0058] The molding apparatus described in this application allows the plates 110 of the combined cold isostatic pressing mold 1 to be detachably assembled into a container 100 with an opening 100a. This enables the cold isostatic pressing mold to be assembled and spliced according to plates 110 of different sizes to form containers 100 of different volumes. Thus, the combined cold isostatic pressing mold 1 can be applied to scenarios where various fixed-size blanks are produced. It is worth noting that the combined cold isostatic pressing mold 1 described in this application is also provided with a pressing component 400. The pressing component 400 is used to apply pressure to the cover 300 so that the cover 300 can be securely placed on the opening 100a. Moreover, the pressing component 400 can be applied to scenarios where various fixed-size blanks are produced, which helps to improve the applicability of the combined cold isostatic pressing mold 1. In addition, when the combined cold isostatic pressing mold 1 is recycled, only the first locking member 200 needs to be disassembled to disassemble the container 100 into separate plates 110. This facilitates recycling and avoids the trouble of cutting and disassembling the combined cold isostatic pressing mold 1, thus improving the ease of recycling the molding device.
[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0060] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
