Description

Technical Field

[0001] This invention relates to the field of mold manufacturing technology, specifically to a directional molding mold with adjustable porosity for ceramic composite wear-resistant materials. Background Technology

[0002] Mold manufacturing technology is a comprehensive engineering technology based on product structure and material properties, involving the design, processing, assembly, and optimization of molding dies. Its core aspects include mold structure design, precision machining (such as CNC milling and EDM), surface treatment, and precision testing. By constructing mold cavities and mechanisms that meet molding process requirements, it enables efficient, batch, and precision molding of materials (metals, plastics, ceramics, etc.). It is a core technology for ensuring product consistency and quality in industrial production, providing crucial process support for the molding applications of various functional materials.

[0003] As a specialized and innovative application of mold manufacturing technology in the field of special materials, this orientation molding mold is specifically designed for the unique molding requirements of ceramic composite materials, focusing on the core challenges of high temperature resistance, high strength, and complex molding processes.

This mold provides crucial molding support for the large-scale application of ceramic composite materials in high-end equipment, and its innovative design can specifically solve molding problems in specific scenarios, making it a core piece of equipment for improving the reliability of ceramic matrix composite components.

[0004] However, in existing technologies, some devices used to prepare ceramic composite wear-resistant materials lack flexible and effective means of porosity control, often relying on fixed mold structures or single raw material ratios. This makes it impossible to precisely adjust the number and distribution density of pores according to different working conditions. The porosity is often within a fixed range, making it difficult to adapt to diverse application scenarios. This results in materials either having excessive pores that affect wear resistance or insufficient pores that fail to meet specific heat dissipation, weight reduction, or other requirements. The materials exhibit poor adaptability and low customization, failing to support the personalized preparation of high-performance ceramic composite wear-resistant materials.

[0021] Compared with the prior art, the advantages of the present invention are as follows:

[0022] 1. In this invention, the working time and output power can be adjusted by using a micro unidirectional blowing pump to precisely control the amount of borosilicate glass powder conveyed. Combined with the sealing gasket and the annular gap between the inner and outer tubes and the groove of the inner tube, the powder is evenly dispersed in the ceramic mud.

It can adapt to the forming needs of ceramic blanks of various specifications and shapes, greatly improve the versatility and flexibility of the mold, and reduce the equipment investment cost for the production of various types of products.

[0024] 3. In this invention, the clamping mechanism consisting of the insert and the air groove achieves stable installation and fixation of the mold cup. During installation, the insert is inserted into the inner wall of the bottom of the mold cup for precise positioning, preventing the mold cup from shifting during the extrusion process. The air groove on the surface of the insert can promptly expel air from the mold cup, ensuring smooth installation. At the same time, clamping plates one and two clamping plates clamp the mold cup through the transmission of the rotating rod and the threaded rod. The anti-detachment ring and the limiting piece further ensure the stability of the clamping structure. The dual positioning and clamping design effectively improves the forming accuracy of the ceramic blank and reduces blank defects caused by mold cup displacement. Attached Figure Description

[0036] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0037] like Figures 1 to 9The illustration shows an embodiment of an adjustable porosity directional molding die for ceramic composite wear-resistant materials provided by the present invention. It includes a body 1 that supports various components and provides an installation base. An extrusion assembly is fixedly connected to the top of the body 1 to extrude and shape the ceramic clay. The extrusion assembly includes multiple limiting posts 2 fixed to the top of the body 1, providing guidance for the lifting and lowering of the mounting plate 5 and ensuring the smooth descent of the mold 6. Pushing cylinders 3 are fixedly connected to the top of the multiple limiting posts 2, providing extrusion power to push the mounting plate 5 and the mold 6 downwards. A limiting plate 4, sliding outside the limiting posts 2, is fixedly connected to the outside of the pushing cylinder 3, fixing the pushing cylinder 3 and enhancing its installation stability. The output end of the pushing cylinder 3 is fixedly connected to the mounting plate 5, connecting the pushing cylinder 3 and the mold 6 to transmit extrusion force. The bottom of the mounting plate 5 is fixedly connected to the mold 6, which directly contacts the ceramic clay to apply pressure, compacting the ceramic clay into shape.

[0038] A support platform 7 is fixedly connected to the top of the machine body 1, which supports the clamping assembly, mold cup 14, extraction assembly, etc., providing a stable installation and working platform. The clamping assembly is fixedly connected to the top of the support platform 7 to clamp and fix the mold cup 14, preventing displacement during extrusion. The clamping assembly includes a clamping plate 8 fixed to the top of the support platform 7, which serves as a reference for clamping and provides clamping support; a clamping plate 9 is also slidably connected to the top of the support platform 7, which, by sliding close to the clamping plate 8, clamps the mold cup 14; two rotating rods 10 are rotatably connected to the inner wall of the clamping plate 8, which are turned by the operator to drive the threaded rod 11 to rotate; a threaded rod 11 that is threadedly connected to the right side of the rotating rod 10 is fixedly connected to the clamping plate 9, which pushes the clamping plate 9 to slide through the threaded transmission to adjust the clamping distance; an anti-detachment ring 12 that rotates on the inner wall of the clamping plate 8 is fixedly connected to the outside of the rotating rod 10 to ensure that the rotating rod 10 only rotates and does not axially displace and disengage, thus ensuring transmission stability; a limit piece 13 is fixedly connected to the right side of the threaded rod 11 to prevent the clamping plate 9 from sliding excessively and disengaging from the threaded rod 11, thus limiting the clamping stroke.

[0039] The top of the support platform 7 is equipped with a mold cup 14 to hold ceramic clay, providing a molding space for the ceramic blank, and it can be replaced to adapt to different shape requirements. The top of the support platform 7 is also equipped with an extraction component to extract and transport borosilicate glass powder, providing raw materials for pore formation. The extraction component includes a miniature unidirectional blowing pump 15 fixed to the top of the support platform 7. By adjusting the working time and output power, the amount of borosilicate glass powder delivered can be precisely controlled, providing power for porosity regulation. The input end of the miniature unidirectional blowing pump 15 is fixedly connected to a flexible hose 16, which facilitates the extraction of borosilicate glass powder from the sandbox 27 and allows for the extraction of additional raw materials, making operation convenient. The output end of the miniature unidirectional blowing pump 15 is fixedly connected to a delivery pipe 17, which transports the borosilicate glass powder extracted by the miniature unidirectional blowing pump 15 to the internal cavity of the mounting platform 18.

[0040] One end of the extraction component is fixedly connected to the mounting platform 18, which connects the extraction component and the outer tube 19, providing an intermediate carrier for powder transfer and component installation; the outer side of the conveying pipe 17 is fixedly connected to the inner wall of the mounting platform 18, fixing the conveying pipe 17 and ensuring the stability of the powder transfer channel. The top of the mounting platform 18 is threadedly connected to an outer tube 19, which, together with the inner tube 22, forms an annular gap to guide the transport of borosilicate glass powder. It is also connected to the mounting platform 18 via a threaded ring 21, facilitating the disassembly and replacement of the mold cup 14. The bottom of the outer tube 19 is fixedly connected to a threaded ring 21, achieving a threaded connection between the outer tube 19 and the mounting platform 18, ensuring stable installation and easy disassembly. The inner wall of the threaded ring 21 is threadedly connected to the top of the mounting platform 18, enabling detachable fixing of the outer tube 19 to the mounting platform 18. A rubber gasket 20 is fixedly connected to the bottom of the outer tube 19, enhancing the sealing at the connection between the outer tube 19 and the mounting platform 18 and preventing borosilicate glass powder leakage. The outer surface of the rubber gasket 20 is in close contact with the inner wall of the top of the mounting platform 18, further improving the sealing effect at the connection and preventing powder leakage.

[0041] An inner tube 22 is slidably connected to the inner wall of the outer tube 19, forming an annular gap with the outer tube 19. Borosilicate glass powder is guided through surface grooves to flow evenly from the holes in the top plate 24, and can slide along the inner wall of the outer tube 19, adapting to the extrusion process. The inner diameter of the inner tube 22 is smaller than that of the outer tube 19, forming an annular gap and providing a channel for the transport of borosilicate glass powder. Multiple grooves are formed on the surface of the inner tube 22 to allow the borosilicate glass powder to flow in, and then flow out from the holes around the top plate 24 into the ceramic... Inside the ceramic clay, the powder is evenly dispersed. The inner tube 22 is fixedly connected to a sealing gasket 23 that slides on the inner wall of the outer tube 19, forming a sealed structure to prevent borosilicate glass powder from leaking from the gap between the inner tube 22 and the outer tube 19, ensuring accurate powder delivery. The top of the inner tube 22 is fixedly connected to a top plate 24 that can fit tightly against the inner wall of the top of the mounting platform 18. This plate can fit tightly against the inner wall of the top of the mounting platform 18 during the final compaction stage to enhance the sealing effect, while ensuring that no marks are left on the bottom of the formed ceramic.

[0042] The top of the mounting platform 18 is fixedly connected with multiple inserts 25, which are inserted into the inner wall of the bottom of the mold cup 14 to accurately position the mold cup 14 and prevent it from shifting during compression. The outer side of the inserts 25 is in close contact with the inner wall of the mold cup 14 to enhance the positioning effect of the mold cup 14 and improve the installation stability. Multiple air grooves 26 are opened on the surface of the inserts 25 to expel the air in the mold cup 14 in time, ensuring smooth installation of the mold cup 14 and improving installation stability.

[0043] A sand box 27 is fixedly connected to the top of the machine body 1 to store borosilicate glass powder and provide raw material storage space for powder extraction; a guide block 28 is fixedly connected to the inner wall of the sand box 27 to guide the powder to gather at the bottom of the hose 16, so as to avoid the powder accumulating in the corner of the sand box 27 and causing waste; one end of the hose 16 is inserted into the inner wall of the sand box 27 to extract the borosilicate glass sand, accurately extracting the borosilicate glass powder in the sand box 27 to provide raw materials for pore formation.

[0044] Working principle: Before use, borosilicate glass powder is loaded into the sand box 27. The guide block 28 inside can guide the powder to gather at the bottom of the hose 16, avoiding the powder from accumulating in the corner of the sand box 27 and causing waste. When the powder in the sand box 27 is insufficient, the hose 16 is made of flexible material, so the hose 16 can be directly pulled out to replenish the raw material through the hole at the top of the sand box 27, which is convenient to operate. The mold cup 14 containing ceramic clay is then placed between clamping plates 8 and 9 on the support platform 7. The rotating rod 10 is turned, causing the threaded rod 11, which is fixedly connected to it, to rotate. Since the threaded rod 11 is threadedly engaged with clamping plate 9, and clamping plate 9 is slidably connected to the top of the support platform 7, the rotation of the rotating rod 10 pushes clamping plate 9 closer to clamping plate 8, thus clamping and fixing the mold cup 14. The anti-detachment ring 12 on the outside of the rotating rod 10 ensures that the rotating rod 10 only rotates and does not axially displace or detach. The limiting piece 13 on the right side of the threaded rod 11 prevents clamping plate 9 from excessively sliding off the threaded rod 11, ensuring the stability of the clamping structure. Simultaneously, the insert 25 on the top of the mounting platform 18 is inserted into the inner wall of the bottom of the mold cup 14 to further position the mold cup 14, preventing it from shifting during the pressing process. The air groove 26 on the surface of the insert 25 can expel air from inside the mold cup 14, ensuring a smooth installation process.

[0045] After the raw materials and mold cup 14 are ready, the extraction and extrusion components work together: the micro unidirectional blowing pump 15 is powered on and runs. This pump draws borosilicate glass powder from the sand box 27 through the hose 16, and then transports the powder to the internal cavity of the mounting platform 18 through the delivery pipe 17. According to the required porosity of the ceramic blank, the amount of borosilicate glass powder delivered can be precisely controlled by adjusting the working time and output power of the micro unidirectional blowing pump 15, thereby achieving flexible control of porosity. After the borosilicate glass powder enters the mounting platform 18, it is further transported to the inside of the outer tube 19. Since the inner tube 22 slides against the inner wall of the outer tube 19 through the sealing gasket 23, the accumulation of powder will push the inner tube 22 to slide upward. At this time, the sealing gasket 23 can form a sealing structure to prevent powder leakage. The outer tube 19 is threadedly connected to the mounting platform 18 through the threaded ring 21 at the bottom, and the rubber gasket 20 at the bottom of the outer tube 19 is in close contact with the inner wall of the top of the mounting platform 18, further enhancing the sealing of the connection and avoiding powder leakage that could lead to waste or porosity control errors.

[0046] The extrusion assembly is then activated to extrude and shape the ceramic clay. Multiple limiting posts 2 at the top of the machine body 1 guide the lifting and lowering of the mounting plate 5. Upon activation, its output pushes the mounting plate 5 downwards smoothly along the limiting posts 2, causing the pressure mold 6 at the bottom of the mounting plate 5 to approach and apply pressure to the ceramic clay within the mold cup 14. Under pressure, the ceramic clay deforms and penetrates downwards. The extrusion top plate 24 drives the inner tube 22 to slide downwards along the inner wall of the outer tube 19. Since the inner diameter of the outer tube 19 is larger than that of the inner tube 22, an annular gap is formed between them. Multiple slots are opened on the surface of the inner tube 22, allowing borosilicate glass powder from the outer tube 19 to enter the inner tube 22 through this annular gap and flow out from the slots around the top plate 24, dispersing evenly and being enveloped by the ceramic clay. As the pushing cylinder 3 continues to apply pressure, the ceramic clay is gradually spread out, and the borosilicate glass powder is evenly distributed inside the ceramic clay, ultimately forming a dense ceramic blank with uniformly distributed borosilicate glass powder.

[0047] To prepare ceramic blanks of different shapes, the threaded ring 21 at the bottom of the outer tube 19 can be unscrewed, the outer tube 19 can be disassembled, and a mold cup 14 of the appropriate shape can be replaced. Then, the outer tube 19 can be reinstalled and positioned by the insert post 25 and clamped by the clamping plate assembly to meet the forming requirements of multiple specifications of blanks. After forming, the clamping assembly can be disassembled and the ceramic blank can be taken out. During subsequent high-temperature firing, the borosilicate glass powder will melt and fuse with the ceramic matrix in a range lower than the ceramic sintering temperature, ultimately forming the preset pores inside the ceramic.
