Description

Technical Field

[0001] The utility model relates to the technical field of vacuum sintering furnaces, in particular to a vacuum sintering furnace for liquid-cooled connector parts. Background Art

[0002] The pitch of the microchannel teeth of the liquid cooling plate is on the order of 0.1mm (the air cooling is at the millimeter level), and the design and processing need to consider the flow channel and flow resistance more accurately; the water cooling plate and the fixed plate are integrated to ensure that there is no leakage. Each liquid-cooled server has a water inlet pipe and a water outlet pipe, and is equipped with at least four plugs, which are high-precision quick-connect plug components. In the processing of the components of the liquid cooling connector, each processing step must be strictly controlled. After injection molding and heating, sintering is completed in a vacuum environment to avoid oxidation, reduce impurities, and ensure the thermal conductivity, sealing and dimensional accuracy of the components.

[0003] The existing patent announcement number CN223192084U discloses a powder vacuum sintering furnace, which includes a vacuum sintering furnace body, a temperature control mechanism, a heat dissipation mechanism and a sealing cover. The vacuum sintering furnace body and the temperature control mechanism are connected by a pipeline. The heat dissipation mechanism is provided on the vacuum sintering furnace body. The sealing cover is rotatably connected to the vacuum sintering furnace body. The vacuum sintering furnace body is fixedly connected to a sintering bracket. The sintering bracket is fixedly provided with a magnet bar. Heating rings are evenly arranged on the inner wall of the vacuum sintering furnace body. Grooves and exhaust holes corresponding to the sealing mechanism of the sealing cover are provided at the joints between the two ends of the sintering furnace body and the sealing cover to realize the adsorption of the magnetic block and the magnetic strip when the sealing cover is closed, drive the extension of the telescopic rod, and engage the rubber strip and the protrusion into the rubber groove and the exhaust hole accordingly to complete the sealing of the entire furnace body.

[0004] When opening the sealed cover of the aforementioned vacuum sintering furnace, operators must overcome the strong magnetic attraction to separate the magnetic block from the magnet bar. In a vacuum environment, the strong negative pressure within the furnace further amplifies this resistance. Furthermore, high temperatures can further deteriorate the magnetic and rubber properties, making opening more difficult or even causing seal failure after long-term use. To address these issues, a liquid-cooled vacuum sintering furnace for connector components was proposed. Utility Model Content

[0034] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediate medium; internal communication between two components, or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See also Figures 1-8 In this embodiment, a vacuum sintering furnace for liquid-cooled connector parts includes:

[0037] The vacuum sintering furnace body 1 comprises a furnace body 11 and a docking ring 12 connected to one end of the furnace body 11;

[0038] The furnace cover 2 includes a cover body 21, a plurality of docking blocks 22 connected to the outer ring of the cover body 21, and a sealing ring 24 connected to one side of the cover body 21; the sealing ring 24 is in close contact with the docking ring 12; the sealing ring 24 can be made of fluororubber; when the sealing ring 24 and the docking ring 12 are assembled, the protrusion on one side of the docking ring 12 (the docking ring 12 is an existing vacuum sintering furnace structure, and the protrusion is annular) is placed in the inner wall of the sealing ring 24. In actual production, the sealing ring 24 is integrally formed according to the design requirements. The structure of the sealing ring 24 can refer to Figure 8 , the size and structure will be adjusted according to actual production;

[0039] The docking ring 12 is an existing vacuum sintering furnace structure. Figure 4 and Figure 5 The detailed structure is not shown, which does not affect the integrity of the scheme;

[0040] The rotating structure 3 includes a rotating base 31 connected to the outer wall of the furnace body 11, a rotating column 32 rotatably connected to the rotating base 31, and a connecting plate 33 fixedly connected to one side of the rotating column 32. The end of the connecting plate 33 is connected to the cover body 21 via a floating member 34. A stopper 35 is installed on the rotating base 31 for fixing the position of the connecting plate 33 when the cover body 21 is opened;

[0041] The locking structure 4 includes a rotating ring 41 rotatably connected to the docking ring 12, a positioning block 42 connected to the inner ring of the rotating ring 41, and an adjusting member 43 for adjusting the rotation of the rotating ring 41. The docking block 22 is provided with an inclined surface 221 and a pressing surface 222 on the side away from the docking ring 12, which contact the positioning block 42. The positioning block 42 of the locking structure 4 cooperates with the inclined surface 221 and pressing surface 222 of the docking block 22. Through the angled design, the rotational force is converted into axial pressure, and combined with the sealing ring 24, a tight seal is achieved.

[0042] During docking, the sealing ring 24 contacts the docking ring 12. After the furnace cover 2 is further pressed inward, the sealing ring 24 is partially deformed and compressed. The assembly compression rate is designed to be 15% to 25%.

[0043] See also Figure 2 The thickness of the inclined surface 221 at one end away from the pressing surface 222 is smaller than that at the pressing surface 222, and the angle between the inclined surface 221 and the pressing surface 222 is 10° to 15°; when the positioning block 42 moves to the side of the docking block 22, the pressure of the positioning block 42 is transmitted through the inclined surface, so that the cover body 21 fits tightly toward the docking ring 12, and cooperates with the sealing ring 24 to achieve stable sealing.

[0044] When the rotating ring 41 starts to rotate and the positioning block 42 enters the area of ​​the docking block 22, it will first encounter the inclined surface 221 with a smaller radial dimension. The positioning block 42 will not touch the pressing surface 222, but will naturally be placed on one side of the end of the inclined surface 221 and will first contact the inclined surface 221. As the rotating ring 41 continues to rotate, the positioning block 42 is forced to slide along the surface of the inclined surface 221. During the sliding process, the rotational motion is converted into an axial clamping force. When the positioning block 42 slides over the inclined surface 221 and finally reaches the pressing surface 222 with the largest radial dimension, the sliding process ends and is clamped through surface contact.

[0045] See also Figure 3 The floating member 34 includes two sets of guide bars 341 fixedly connected to one side of the cover 21. The end of the connecting plate 33 is connected to the positioning rod 342. The guide bars 341 are provided with strip holes 343 for the positioning rod 342 to slide horizontally. The top and bottom of the connecting plate 33 near the positioning rod 342 are connected to limit plates 344, which are slidably connected to one side of the guide bars 341. Specifically, when the cover 21 moves toward the docking ring 12, the end of the positioning rod 342 slides within the strip holes 343, and the limit plates 344 slide against both sides of the guide bars 341 to ensure movement stability. The limit plates 344 of the floating member 34 limit the relative movement range between the cover 21 and the connecting plate 33, preventing the components from disengaging.

[0046] See also Figure 6The limiting member 35 includes a cylinder 351 connected to the top and bottom of the rotating base 31. The power output end of the cylinder 351 near one end of the connecting plate 33 is connected to a plug rod 352. The connecting plate 33 is connected to a socket for inserting the plug rod 352 at both the top and bottom. A contact switch 353 is provided on one side of the rotating base 31, which can contact the connecting plate 33. The rotating base 31 is mounted with a controller 354 for controlling the operation of the cylinder 351. Specifically, the contact switch 353 senses the position of the connecting plate 33, and the controller 354 controls the cylinder 351 to push the plug rod 352 into the socket of the connecting plate 33, thereby fixing the cover 21 in the open state. The cylinder 351 and plug rod 352 of the limiting member 35 automatically fix the cover 21 in the open state, preventing accidental closure and improving operational safety.

[0047] See also Figure 5 The adjusting member 43 includes an electric telescopic rod 431, and the outer wall of the furnace body 11 is connected to a fixed block 432 rotatably connected to one end of the electric telescopic rod 431, and one side of the rotating ring 41 is connected to a fixed column 433 rotatably connected to the other end of the electric telescopic rod 431; specifically, the rotating ring 41 can be adjusted to rotate through the electric telescopic rod 431, and the fixed block 432 can correspond to the docking block 22.

[0048] See also Figure 1 The cover 21 is connected to a handle 23 on the side away from the docking ring 12, and the handle 23 is used to facilitate opening the cover 21. The rotating structure 3 realizes the flip opening and closing of the cover 21 through the rotating column 32 and the connecting plate 33, and cooperates with the handle 23 to reduce the operating intensity.

[0049] Furthermore, the bottom of the furnace body 11 is connected to support legs 13. The support legs 13 enhance the support stability of the furnace body 11 and ensure sintering accuracy.

[0050] Furthermore, a liquid-cooling connector component placement cavity 14 is provided inside the furnace body 11 , and the liquid-cooling connector component is placed in the liquid-cooling connector component placement cavity 14 inside the furnace body 11 .

[0051] The working principle of the present invention is as follows: the operator pulls the cover 21 through the handle 23, and under the action of the rotating structure 3, the rotating column 32 rotates around the rotating connection with the rotating seat 31, driving the connecting plate 33 and the cover 21 to flip open. At this time, the contact switch 353 in the limiter 35 senses the position of the connecting plate 33, and the controller 354 controls the cylinder 351 to push the insertion rod 352 into the insertion hole of the connecting plate 33, fixing the open state of the cover 21, and facilitating the placement of the liquid-cooling connector components into the liquid-cooling connector component placement cavity 14 inside the furnace body 11;

[0052] After the loading is completed, the controller 354 controls the cylinder 351 to retract the insertion rod 352, releasing the limit, and the operator pushes the cover body 21, and the cover body 21 is covered on the docking ring 12 by the rotating structure 3. The sealing ring 24 on one side of the cover body 21 fits with the docking ring 12, and a preliminary seal is formed;

[0053] The adjusting member 43 drives the rotating ring 41 to rotate, causing the positioning block 42 on the inner ring of the rotating ring 41 to contact and slide with the inclined surface 221 of the docking block 22, and finally move to the pressing surface 222, pressing the docking block 22. Since the inclined surface 221 and the pressing surface 222 are at an angle of 10°-15°, the pressure of the positioning block 42 is transmitted through the inclined surface, causing the cover body 21 to fit tightly toward the docking ring 12, and cooperate with the sealing ring 24 to achieve a stable seal.

[0054] The guide strips 341, positioning rods 342, and strip-shaped holes 343 allow for fine-tuning of the cover 21 laterally to avoid poor sealing due to rigid contact. The stopper plates 344 prevent the cover 21 from separating from the connecting plate 33, ensuring movement stability.

[0055] After the furnace body 11 is closed, the external vacuum system is started. The vacuum system is a conventional configuration and will not be described in detail in this application. Then, sintering and heating are carried out. The legs 13 at the bottom of the furnace body 11 ensure the overall stability of the equipment.

[0056] After sintering is completed, the adjusting member 43 drives the rotating ring 41 to rotate in the opposite direction, the positioning block 42 disengages from the docking block 22, and the lock is released. The operator opens the cover 21 through the handle 23, and the limit member 35 fixes the position of the cover again, making it easy to remove parts.

[0057] The controller 354 is used to receive the signal of the contact switch 353 and output the control signal to drive the cylinder 351 to move. The controller 354 can be a Siemens series product, which can be selected according to actual needs; the cylinder can be a SMCCDJ2B series small cylinder; the contact switch can be an Omron D4V series travel switch.

[0058] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
