[0002] With the widespread use of metal-based ceramic composites, their preparation technology has developed rapidly in recent years. Currently, the most mature method is vacuum pressure infiltration. This method primarily uses gas pressure to infiltrate molten metal into the gaps between ceramics, where it subsequently solidifies into a metal-based ceramic composite. However, this method has specific requirements for the sequence of vacuuming, metal melting, and infiltration. The workpiece is placed in a basket, which is then lowered into a sealed barrel using a crane to achieve the infiltration process.

[0003] During loading and unloading, the basket is placed inside the sealed barrel and comes into contact with the impregnation liquid inside. At this time, the impregnation process begins. When the seal is completed by closing the lid and vacuuming, part of the workpiece surface has been impregnated. This results in different quality of the same batch of parts during impregnation and the inability to control the consistency of the material. Utility Model Content

[0022] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0023] Please refer to Figure 1 and Figure 2 As shown, a metal-based ceramic composite material infiltration tooling includes a support platform 1 and a basket 8. A barrel body 2 is installed on the top of the support platform 1. The barrel body 2 is hollow inside and has an open top. A sealing cover 3 is installed on the rear side of the top of the barrel body 2. The sealing cover 3 is controlled by a hydraulic mechanism to realize whether the top of the barrel body 2 is sealed to ensure that a sealed space is formed in the barrel body 2 during operation. The sealing cover 3 is adapted to the size of the opening at the top of the barrel body 2. Cavities 6 are symmetrically arranged on the lower sides of the inner wall of the support platform 1. A lifting rod 7 is vertically slidably installed on the top of the cavity 6. The lifting rod 7 can slide in the vertical direction. A fixing bolt 71 is provided on the top of the lifting rod 7. The basket 8 is placed on the inner side of the barrel body 2. The top of the basket 8 is open. Extension plates 81 are symmetrically arranged on both sides of the top of the basket 8. A through hole adapted to the fixing bolt 71 is opened on the surface of the extension plate 81 to ensure the stability of the installation of the basket 8 and the top of the two lifting rods 7 through the cooperation of the two.

[0024] Please refer to Figure 2 and Figure 3 As shown, a piston head 72 is provided at the bottom of the lifting rod 7, and the piston head 72 slides on the inside of the cavity 6. A spring 9 is provided on the inside of the cavity 6. The top of the spring 9 is provided to contact the lower surface of the piston head 72. The piston head 72 is pushed by the spring 9 so that the piston head 72 is placed at the top when not subject to external force, so as to facilitate the installation of the basket 8 from above. Air outlet holes 10 are symmetrically opened on the lower sides of the barrel body 2. The air outlet holes 10 are connected with the bottom of the cavity 6 and are placed on the lower surface of the support platform 1 so that the cavity 6 is connected with the external air.

[0025] Among them, a sliding plug 11 slides through the inside of the air outlet 10, and an I-head A13 is provided at the end of the sliding plug 11. The I-head A13 is placed on the outside of the barrel body 2. The I-head A13 facilitates the control of the sliding plug 11. A connecting hole 12 is provided at the end of the sliding plug 11 away from the I-head A13. The connecting hole 12 is L-shaped. The L-shaped structure can control whether the cavity 6 is connected to the outside by sliding the sliding plug 11, and the small-sized connecting hole 12 can reduce the flow speed of the air, so that the process of moving downward in the basket 8 is slow, forming a damping effect.

[0026] Please refer to Figure 4 and Figure 5 As shown, movable rods 14 are symmetrically provided on both sides of the lower surface of the support platform 1 through a pin axis, and U-shaped fork rods 15 are provided at both ends of the movable rod 14. The rear end U-shaped fork rod 15 is stuck on the surface of the I-head A13. The lateral position of the sliding plug 11 can be controlled by rotating the movable rod 14, and then whether the connecting hole 12 is ventilated can be controlled. Bumps 16 are symmetrically provided on the front side of the lower surface of the support platform 1, and a sliding rod 17 slides through the inner side of the bump 16. An I-head B171 is provided at one end of the two sliding rods 17 facing away from each other, and the front end U-shaped fork rod 15 is stuck on the I-head B171. The angle of the movable rod 14 is controlled by the sliding rod 17. When the two sliding rods 17 approach each other, the two sliding plugs 11 can be driven to slide outward at the same time.

[0027] Among them, an adjusting bolt 18 is vertically screwed through the front side of the support platform 1, and an extrusion cone head 19 is provided at the bottom of the adjusting bolt 18. The two sides of the extrusion cone head 19 are respectively in contact with the end of the slide rod 17. By rotating the adjusting bolt 18 to control the downward movement of the extrusion cone head 19, the two slide rods 17 are separated, and then the slide plug 11 is pushed out of the air hole 10 and kept fixed.

[0028] Please refer to Figure 1 As shown, an observation window 4 is provided on the front side of the barrel body 2 for easy observation of the interior. An air pressure detection gauge 5 is installed on the surface of the barrel body 2.

[0029] The working principle of the present invention is as follows: rotating the adjustment bolt 18 can control the height of the extrusion cone 19, and then control the extrusion of the slide bars 17 on both sides, and synchronously adjust the angles of the movable bars 14 on both sides to control the sliding distance of the I-head A13 and the sliding plug 11. Before placing the basket 8, the sliding plug 11 can be controlled to move outward, and the end of the communicating hole 12 is ventilated to the outside. At this time, the internal pressure of the cavity 6 is equal to that of the outside. The elastic force of the spring 9 is used to place the lifting rod 7 at the top of the stroke, and then the sliding plug 11 is slid inward to seal the communicating hole 12. At this time, the internal stroke of the cavity 6 is a closed space, and then the basket 8 is installed on the top of the two lifting rods 7. The height of the basket 8 can be guaranteed by the fixing bolt 71. Since the gas inside the cavity 6 cannot flow out and the elastic force of the spring 9 is added, the upper part of the barrel body 2 of the basket 8 will not be soaked with liquid. Contact, then close the sealing cover 3, so that the interior of the barrel body 2 is sealed and vacuumed. When the internal pressure is reached, the limit of the sliding plugs 11 on both sides is released at the same time, so that the end of the connecting hole 12 is connected to the outside. At this time, the gas inside the cavity 6 can be slowly discharged through the connecting hole 12, and the basket 8 is used to slowly fall, so that the composite material is immersed in the liquid. After the impregnation is completed, the sealing cover 3 is opened, and because of its basket 8, unloading is achieved. Since the end of the connecting hole 12 is ventilated, the spring 9 is used to move the lifting rod 7 back to its position. Before the next loading, the sliding plug 11 is slid inward and sealed. When it is necessary to deflate, the extrusion cone 19 is moved up so that it no longer squeezes the sliding rod 17. At this time, the pressure inside the cavity 6 can be used to push the sliding plug 11 out. During debugging, the lifting rod 7 can be manually pressed down to achieve the ejection of the sliding plug 11.

It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention.
